DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microbial deodorizer with a dust separator for separating dust and the like in exhaust gas and decomposing odorous components with microorganisms.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 8, this type of deodorizing apparatus a contains dust and odor components under a deodorizing layer c in which activated carbon is filled as a deodorizing agent in a tower body b. The exhaust gas g is supplied, and the treated water w of the water storage section d provided at the lower part in the tower body b and appropriately replenished is discharged to the exhaust gas g by the water supply system wr.
After removing dust and water-soluble odor components from the exhaust gas g by showering, the primary-treated exhaust gas g is passed through a deodorizing layer c to be deodorized.

However, the deodorizer a has a drawback that a driving source p is required in the water supply system wr in order to shower the treated water w in the form of droplets with respect to the exhaust gas g. . Further, in the conventional deodorizer a, the exhaust gas g
The water-soluble odor component contained in the deodorant layer c is merely removed by showering with treated water w, and the non-water-soluble odor component that cannot be removed rises and reaches the activated carbon of the deodorizing layer c. The water-insoluble odor component is adsorbed in the pores of the activated carbon, and the exhaust gas g is deodorized and released to the atmosphere, while the innumerable pores of the activated carbon are clogged by the adsorption of the water-insoluble odor component, Adsorption and deodorization ability was reduced, and it had the fault which required periodic exchange of activated carbon.

[0004] Activated carbon has a large adsorptivity and retention of sulfur compounds such as methyl mercaptan and methyl sulfide, alcohols, fatty acids, halogenated hydrocarbons, aliphatic hydrocarbons, aromatic hydrocarbons and esters. Formula 1 formic acid, formaldehyde, methyl alcohol, propane,
Methyl chloride and the like hardly adsorb, and ammonia, hydrogen sulfide and the like have only a small adsorptive power. As a result, even if a part of the odor component can be adsorbed, it is difficult to adsorb a part of the odor component, and for exhaust gas g containing various odor components,
There was a disadvantage that sufficient deodorization could not be performed.

[0005]

SUMMARY OF THE INVENTION The present invention eliminates dust and the like without requiring power, prevents a decrease in the adsorbing power of a deodorant due to clogging, maintains the deodorizing ability, and maintains various odors. Provided is a microorganism deodorizing apparatus equipped with a dust separator that enables sufficient deodorization of components.

[0006]

SUMMARY OF THE INVENTION The present invention is based on the above-mentioned prior art, and requires the power to remove dust, the clogging of the deodorant, the reduction of the deodorizing ability, and the reduction of some types of odor components. In consideration of the difficulty of removal, deodorization chambers and dust collection chambers are provided above and below the tower body, and an air supply device is installed between the downstream deodorization chamber and the upstream dust collection chamber. By filling the adsorbent carrying microorganisms in the dust collection chamber and providing an exhaust gas inflow duct in the dust collection chamber, dust and the like are separated from the exhaust gas in the dust collection chamber, and the odor components are adsorbed by the adsorbent and microorganisms in the deodorization chamber. After that, it is decomposed and deodorized.
Further, the present invention provides a microbial deodorizing apparatus with a dust separator, wherein a flow path other than a straight line is formed as a flow path of exhaust gas in a dust collection chamber, and dust and the like are separated from the exhaust gas by its inertia.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. A deodorizing device 1 according to the present invention is shown in FIG.
As shown in FIGS. 2 and 4, the deodorizing device 1 is connected to an exhaust gas generation source 2 and includes a tower body 4 mounted on a base 3 and an air supply device 5. Further, a deodorizing chamber 6 on the downstream side and a dust collecting chamber 7 on the upstream side are respectively provided above and below the tower main body 4, and an air supply device 5 is interposed between the deodorizing chamber 6 and the dust collecting chamber 7.

[0008] As an example of the exhaust gas generation source 2,
There is a fermentation treatment device that recycles organic waste. Such a fermentation treatment device performs biofermentation treatment of organic waste such as garbage, sludge, animal residue, and the like, and organic fertilizer, soil conditioner, etc. As resources.

As shown in FIGS. 1 to 4, a horizontal partition 8 is provided in the internal space of the tower body 4 formed into a bottomed cylindrical body standing upright on the base 3, and Are divided into a deodorizing chamber 6 and a dust collecting chamber 7.

As shown in FIGS. 1 and 4 to 7, the exhaust gas generating source 2 is disposed above the cylindrical dust collecting chamber 7 in the lower part of the tower main body 4 and on the upstream side. And an exhaust gas intake duct 11 connected to the suction side of the air supply device 5, respectively. In the mounting state of the exhaust gas introduction duct 10 with respect to the dust collection chamber 7, the exhaust gas introduction duct 10 is mounted horizontally on the peripheral surface of the dust collection chamber 7 at a position deviated from the center of the dust collection chamber 7. The tip of the exhaust gas introduction duct 10 attached to the wall of the dust collection chamber 7 is extended to the vicinity of the opposed inner wall inside the dust collection chamber 7,
The opening surface of the outlet 12 at the tip is formed so as to be substantially parallel to the inner wall surface. That is, the exhaust gas G sucked in from the outlet 12 of the exhaust gas introduction duct 10 has a flow path in a direction not directed to the center of the dust collection chamber 7, so that the exhaust gas G flowing from the exhaust gas introduction duct 10 The swirling flow is drawn along the inner wall surface of the chamber 7.

The exhaust gas introduction duct 10 for the dust collection chamber 7
Is not limited to the above, and may be any mounting state as long as the exhaust gas G draws a swirling flow. For example, the exhaust gas introduction duct 10 is tangentially mounted on the wall surface of the dust collection chamber 7 and the exhaust gas The outlet 12 of the introduction duct 10 may be opened along the wall surface of the dust collection chamber 7. That is, the outlet 12 of the exhaust gas introduction duct 10 is opened at a position along the inner wall surface or the outer wall surface of the dust collection chamber 7 to generate a swirling flow, and a flow path of the exhaust gas G other than a linear flow is formed. ing. The dust collection method in the dust collection chamber 7 can be variously changed, such as a baffle plate method, in addition to a separation method based on inertia of dust and the like described later.

When the exhaust gas suction duct 11 installed in the dust collection chamber 7 and connected to the air supply device 5 is mounted, the exhaust gas introduction duct 10 is displaced by 180 degrees from the mounting position of the exhaust gas introduction duct 10. The exhaust gas suction duct 11 in a horizontal state extends into the dust collection chamber 7 and is bent toward the center of the dust collection chamber 7 so that the suction port 13 is formed substantially at the center of the dust collection chamber 7. It is open. Although not shown, the suction port 13 is opened in the horizontal direction substantially at the center of the dust collection chamber 7. The intake port 13 may be opened downward by bending.

As shown in FIGS. 1 and 4 to 7, mixed treated water W 2 Z (treated water W 2, makeup water W 1
In addition to the treatment water storage unit 15 for the mixed water of D to be the discharge water W3), the treatment water storage unit 15 is provided with an overflow pipe 16 of the discharge system WY. Also, the bottom wall 17 of the treatment water storage section 15
As shown in FIGS. 5 and 7, by tilting so that one direction or the center is high and the periphery is low, all liquid (discharge water W3) can be discharged when operation is stopped. ing.

In the air supply device 5, FIGS.
As shown in FIG. 2, a blower 19 is mounted on a box 18 provided on the base 3 separately from the tower body 4, and the suction port of the blower 19 is attached to the dust collection chamber 7 at the other end of the exhaust gas suction duct 11. And a discharge port of the blower 19 is attached to an exhaust gas supply duct 20 attached to the deodorizing chamber 6. With this configuration, the exhaust gas G in the dust collection chamber 7 is
The exhaust gas G is sucked from the exhaust gas generation source 2 through the exhaust gas introduction duct 10 by supplying the air to the deodorizing chamber 6 by the action of 19 and by creating a negative pressure in the dust collecting chamber 7. Has formed.

In the deodorizing chamber 6, as shown in FIGS. 1 to 4, an exhaust port 21 is mounted on the upper part of the deodorizing chamber 6, and an adsorbing property is provided in a lower part of the middle of the deodorizing chamber 6. In order to fill with a substance having the following properties, for example, a filler M made of an adsorbent, a partition plate 22 having air permeability and water permeability such as a punching plate or the like is used.
And the filler M is filled on the partition plate 22. Then, in the deodorizing chamber 6, the dust collecting chamber 7 is located below the partition plate 22.
The area above the horizontal partition 8 that is divided into upper and lower portions constitutes an upper water receiving portion 23 of the treated water W2. Further, an upper water receiving portion 23 provided between the horizontal partition 8 and the upper water receiving portion 23 in the deodorizing chamber 6 is provided.
The exhaust gas supply duct 20 connected to the air supply device 5 is opened by penetrating the wall surface of the (deodorizing chamber 6), and this region forms an exhaust gas G inflow space 24. Further, a spray head 25 for spraying the make-up water W1U downward, that is, spraying the filler M in the form of a mist, is disposed in the upper part of the deodorizing chamber 6.

A mist remover (not shown) is provided in an exhaust port 21 provided at the upper end of the tower body 4. As an example of the mist remover, a structure in which fine meshes such as a wire mesh are stacked in layers is used to complicate the flow path of the passing gas. The effect of such a mist remover is that gas easily passes through the space of the net by wiping the wire, whereas mist that is heavier than gas does not change its flow path freely due to inertial force. The mist that comes off the road and contacts the wire, and the mist that contacts the wire adheres to the wire due to its surface tension, collects and coarsens, descends along the wire, and finally overcomes the rising airflow and surface tension. It grows into droplets and falls into the filler M below.

Further, although not shown, a deodorizer containing activated carbon in an air-permeable state may be connected to the exhaust port 21 containing the mist remover. With such a configuration, the exhaust gas G deodorized by the deodorizing action described later is finally discharged to the atmosphere after passing through the deodorizer. In addition, activated carbon has a tendency that its adsorbing ability tends to decrease when adsorbing mist (moisture).

As shown in FIGS. 1, 3, and 4, a horizontal partition 8 that divides the deodorizing chamber 6 and the dust collecting chamber 7 is made to pass therethrough.
A drain pipe 26 that opens to the lower upper water receiving section 23 is vertically provided, and the lower end of the drain pipe 26 is connected to the treatment water storage section 15 of the dust collection chamber 7.
I am immersed in. With this configuration, the makeup water W1U sprinkled by the spray head 25 in the deodorization chamber 6 cleans the filler M, passes through the partition plate 22 having ventilation and water permeability, and descends to reach the upper stage water receiving portion 23. W2 passes through the drain pipe 26 and descends, and flows into the treated water storage unit 15.

The downstream end of the drain pipe 26 for dropping the treated water W2 after the cleaning of the filler M from the upper water receiving part 23 of the deodorizing chamber 6 is opened into the mixed treated water W2Z of the treated water storage part 15. Is better. The reason is that the exhaust gas G forced from the exhaust gas generation source 2 into the deodorization chamber 6 via the air supply device 5 is in a pressure-applied state in the inflow space 24 (upper water receiving portion 23) in the deodorization chamber 6. Further, since the replenishing water W1U to the filler M is not sprayed at all times, the inside of the drain pipe 26 is not watertight due to the treated water W2 falling through the upper water receiving part 23 and the drain pipe 26, and the deodorizing chamber 6 (inflow space) This is because there is a danger that the exhaust gas G in 24) will flow out of the drain pipe 26 to the outside.

The filler M made of an adsorbent to be filled in the deodorizing chamber 6 is selected from two kinds or mixed. As the first type of filler M,
A mixture of soil such as andosol, earth and sand powder, and volcanic ash deposited on the upper part of the weathered sedimentary layer of volcanic eruption products, and granulated solidified by adding glue by mixing rice husks with steamed kun charcoal . Kun charcoal is a substance in an intermediate state between activated carbon and natural organic matter, is a porous substance having adsorptive properties, and has an active ingredient serving as a nutrient source for microorganisms.

Further, as the second type of filler M,
Mainly composed of cristobalite, a kind of silicic anhydride,
In addition, it is a porous material fired and formed using a small amount of quartz, scale silica, chlorite, illite, montmorillonite, etc., and has a large average pore diameter of about 100 mm. It has a property that it is easy to hold, that is, has high supportability.

The packing material M in the deodorizing chamber 6 carries activated sludge bacteria or microorganisms such as photosynthetic bacteria that reduce aerobic and high-load BOD (biochemical oxygen demand).

Next, in the deodorizing chamber 6 and the dust collecting chamber 7 in the tower body 4, the filler M and the mixed treated water W in the treated water storage section 15 are collected.
A configuration for supplying neutral replenishing water W1U and W1D to 2Z will be described. That is, as shown in FIGS. 1, 2, and 4, a water supply pipe WA is configured by connecting a water supply pipe directly connected to a water pipe of a water supply source PW, and the water supply system WA is branched to form a watering system WU and a dilution system. It constitutes a water system WC. A valve 27 is interposed in the dilution water system WC, and a discharge port of the dilution water system WC is connected to the dust collection chamber 7 above the treatment water storage unit 15.
To the side wall of the sprinkler, while the valve 27a
And the downstream end of the watering system WU is connected to the deodorizing chamber 6.
Is connected to a spray head 25 provided at the upper part of the.

The basic operation of opening and closing the valves 27 and 27a attached to the dilution water system WC and the watering system WU is as follows. It is designed to be opened only for a short time in accordance with the status of pollution or periodically. On the other hand, treated water storage unit 15
In the dilution water system WC for supplying the makeup water W1D to the mixed treatment water W2Z, the dilution water system WC is basically always open, and stops when the watering system WU is operated or the inflow amount of the exhaust gas G decreases. Sometimes closed. These are opened and closed by a timer, a control device, a measuring device, or the like, or by a remote manual operation.

As shown in FIGS. 3 and 7, in addition to providing an overflow pipe 16 in the treatment water storage section 15, a vertically permeable measuring pipe is attached outside the dust collecting chamber 7, and upper and lower ends of the measuring pipe are provided. To the mixed treated water W2Z (the treated water W2 and the makeup water W
Opening connections are made above and below the assumed water level of 1D and a mist mixture described later) to form a liquid level gauge 28.

As shown in FIGS. 1 and 4, in the treated water storage section 15 of the deodorizing apparatus 1, the mixed treated water W2
A drainage system WZ is connected to the treatment water storage unit 15 to drain Z as wastewater to the outside. In addition, each of the deodorizing rooms is provided with a window for lighting and an openable door for work, and a makeup water W1U,
In order to prevent freezing of W1D, mixed treatment water W2Z, etc.,
Heaters and thermistors (thermocouples) are installed in various places, and heat insulation materials are used to control cold areas without reducing the activity of microorganisms. The tower body 4 and the like are used to prevent corrosion due to exhaust gas G. Using materials.

Next, the operation of the microorganism deodorizing apparatus with a dust separator according to the present invention will be described. During the initial operation of the deodorizing apparatus 1 of the present invention, supplementary water containing microorganisms is sprinkled on the filler M, and the microorganisms are adsorbed, adhered, propagated and carried on the filler M.

The exhaust gas G sucked into the dust collection chamber 7 from the exhaust gas source 2 connected to the exhaust gas introduction duct 10 of the tower body 4 by the operation of the air supply device 5 is converted into a gas containing an odor component, dust, and the like. And mist, they are separated and removed by collision, contact, adhesion, dropping, etc. on the inner wall surface of the dust collection chamber 7 (details will be described later). Then, the deodorizing chamber 6 is connected to the dust collecting chamber 7 via the exhaust gas suction duct 11, the intermediate blower 19, and the exhaust gas air duct 20 connected to the deodorizing chamber 6 by the air supply device 5.
The exhaust gas G fed to the inflow space 24 of the air rises by the air pressure, passes through the partition plate 22, is fed into the deodorizing chamber 6, and passes through the filled filler M. In the passage process, the odor component in the exhaust gas G is removed by simultaneous progress of the adsorption by the filler M (adsorbent) and the decomposition by the microorganisms carried (adsorbed and adhered and held) by the filler M.

The water-soluble odor component having a hydrophilic acidic group such as ammonia, amine, hydrogen sulfide, formaldehyde, and lower organic acids in the exhaust gas is adsorbed by the filler M and sprinkled. Is dissolved and absorbed in the makeup water W1U contained in the water, and the microorganisms decompose and remove the water-soluble odor component.

The odorless exhaust gas G is removed from the mist when passing through the mist remover at the exhaust port 21, and is finally discharged to the outside air from the exhaust port 21. When a deodorizer containing activated carbon is connected to the exhaust port 21, the exhaust gas G from which the mist has been removed is further deodorized.

The detailed operation of the adsorption, decomposition, and removal of the exhaust gas G by the adsorbent and the microorganisms in the deodorizing chamber 6 is as follows. First, when only the porous material is used as the filler M, the exhaust gas G rises from the inflow space 24 in a pressure-applied state, and rises while passing through the filler M (adsorbent) with a pressure loss. Odor components are adsorbed and attached to the pores and surfaces of the adsorbent. In addition, since the microorganisms are carried in the pores of the filler M, the odor components adsorbed in the pores of the adsorbent are decomposed by the microorganisms.

When the filler M has a nutrient source of microorganisms, the filler M in the deodorizing chamber 6 may be used.
During the passage of the (adsorbent), the odor component is adsorbed and attached to the pores and the surface of the adsorbent. Also, in the pores of the filler M, etc.,
Since the microorganisms grown in the sprinkling of the makeup water W1U are carried, the odor components adsorbed on the pores of the adsorbent are decomposed by the microorganisms.

Although the basic operation of the processing in the deodorizing chamber 6 is substantially the same as described above, the difference between the two types of adsorbents will be described. The adsorbent made of only porous material is different in that the filler M containing a nutrient source has a high decomposing ability, as compared with the high porosity and high adsorbing ability.

The mechanism of deodorization by the two kinds of fillers M will be described in detail while further comparing such actions. On the other hand, the porous only filler M has a high adsorption capacity of the adsorbent, and the odor component is first adsorbed and held by the adsorbent.
Degraded by microorganisms. The other nutrient-containing filler M is
Although the adsorptive capacity is lower than that of the porous filler M, the nutrient-containing filler M is composed of various substances. It is adsorbed in the gap or adheres to the surface of the substance, and is separated and adsorbed from the exhaust gas G. In addition, since the nutrient-containing filler M has water retention and a nutrient source, bacteria and microorganisms are highly proliferative, and the number of bacteria falling due to water sprinkling is small. Due to the large number, the ability to decompose odor components (deodorizing ability) is high, and adsorption and decomposition proceed simultaneously.

[0035] For example, since the organic waste supplied to the exhaust gas generation source 2 is not the same, or is input in large quantities at one time interval, the deodorizing device 1 The intensity of the odor of the exhaust gas G sent to the fluctuates. Then, the exhaust gas G having a strong odor is supplied to the deodorizing chamber 6.
Although the odor is stronger than that in the steady state, the temporary increase in the odor component is dealt with by the high adsorptivity of the porous filler M alone.

Since the nutrients such as microorganisms and bacteria during the steady operation are odor components, when the odor of the exhaust gas G increases and the odor component increases, the number of bacteria temporarily increases and the odor component increases. Due to the decrease in the number of bacteria, the decomposition of the odor component proceeds and the adsorption capacity is restored, and the number of bacteria decreases with a delay.

As a criterion for selecting the filler M, as described above, those having a nutrient source have a high deodorizing ability, and those having only a porous material are more excellent in odor intensity fluctuation. Is used as a main criterion, and a filler M suitable for the type of the exhaust gas G is used alone or in combination. In addition, the filler M containing a nutrient source is formed into a granulated solid by bonding various components with an adhesive. However, since the adhesive is weak to heat, it is necessary to consider the selection of the filler M. In addition, since the filling material M also includes soil mainly composed of volcanic ash, if the filling material M loses its shape, the soil will flow out, water retention will be reduced, and bacterial reproduction will be reduced.

When the treatment is performed in the deodorizing chamber 6, a microbial membrane layer mainly composed of sulfides and dead bodies of microorganisms adheres to the surface and pores of the adsorbent, and the adsorption / decomposition ability is reduced. Sulfate ions create an acidic atmosphere that lowers the pH and inhibits the activation of microorganisms. Therefore, the neutral replenishing water W1U supplied from the water supply source PW is periodically sprayed and sprayed on the filler M from the spray head 25 provided in the deodorizing chamber 6. By this watering, the microbial membrane layer is washed and dropped from the filler M,
Recover the closed pores and regenerate the adsorption capacity of the adsorbent. At the time of this washing, a small amount of microorganisms also fall, but the microorganisms proliferate while decomposing odor components.

The basic purpose of water spray is to clean the adsorbent and adjust the pH. However, the deodorizing chamber 6 has the following purposes. That is, one filler M has a nutrient source, has a breeding environment for microorganisms, and has water retention. The watering of the makeup water W1U by the watering system WU is performed, and the water is contained in the filler M and the microorganisms are retained. The environment is being improved. In addition, as a washing action of the adsorbent, sulfate ions generated by a reaction mechanism at the time of deodorization of activated sludge accumulate in the adsorbent, and P
This prevents H from decreasing (acidifying) and inhibiting the microbial reaction relating to deodorization. In addition, since bacteria and the like are activated at a low temperature, an environment suitable for bacterial propagation (a state having a nutrient source) is formed in the deodorizing chamber 6 where the exhaust gas G is relatively cooled, and the deodorizing ability is maintained. We are trying to increase.

The washing of the filler M is periodically repeated, and the washing water (treated water W2) falls down the partition plate 22, and the treated water W2 passes through the upper water receiving section 23 and the drain pipe 26. hand,
Since the mixed treatment water W2Z in the treatment water storage unit 15 flows into the treatment water storage unit 15, the pH of the mixed treatment water W2Z decreases and is acidified. In addition, treatment water storage section
In 15, the above-mentioned treated water W2 flows down and the mist separated in the dust collection chamber 7 flows in, so that the decrease in PH value and concentration of the mixed treated water W2Z in which these are mixed are accelerated.

Therefore, in order to adjust the concentration and PH of the mixed treated water W2Z, the neutralized makeup water W1D is supplied from the dilution water system WC connected to the water supply source PW to dilute the mixed treated water W2Z. And discharge water W3. The replenishing time of the replenishing water W1D is set to all times other than the sprinkling system WU, or is appropriately performed according to the concentration of the discharge water W3.

The effluent W3 diluted by the make-up water W1D to such an extent that the mixed treated water W2Z clears the drainage standard value is discharged from the discharge system WY. At this time, the inlet of the drainage pipe of the discharge system WY is formed in the mixed treated water W2Z (discharged water W3), and the middle part of the overflow pipe 16 is arranged at a predetermined height (overflow method), so that the treated water storage section is formed. The water level of the effluent water W3 within 15 is above a certain level. Note that the dust collection chamber 7 provided with the treatment water storage section 15 is provided.
Is in a negative pressure state due to the action of the air supply device 5,
Although the water level of No. 3 tends to rise, the water level is measured by the liquid level gauge 28 and the overflow pipe 16 is formed to have a necessary diameter to cope with the problem.

Here, the operation of the dust collecting chamber 7 and the mist generated will be described. Since the exhaust gas G sucked from the exhaust gas generation source 2 contains moisture such as dust and water vapor, the exhaust gas G collides with the inner wall surface of the dust collection chamber 7 when flowing into the dust collection chamber 7 or The dust and the mist separate from the exhaust gas G by inertia force, and fall down along the inner wall surface of the dust collecting chamber 7 or fall in the air, and fall into the treatment water storage section 15 and flow. Also, when the intake port 13 of the exhaust gas intake duct 11 is downward, the flow path has a downward flow and an upward flow,
The efficiency of the above separating operation is improved. Also, as shown in FIGS. 1 to 4, by providing a flow control valve 29 for the exhaust gas G in the exhaust gas air duct 20, the amount of the exhaust gas G sucked into the dust collecting chamber 7 can be reduced and adjusted to an appropriate amount. In addition to optimizing the separating action of the deodorizing, the deodorizing chamber 6 is prevented from being insufficiently deodorized.

The types and functions of the deodorizing bacteria and microorganisms will be described below. In the above description, the photosynthetic bacteria and the activated sludge are carried on the filler M as the microorganisms and bacteria of the deodorizing device 1. However, the following operations also occur during the steady operation of the deodorizing device 1. . Microorganisms that decompose odor components and the like are mainly photosynthetic bacteria capable of BOD high-load operation and activated sludge bacteria suitable for environments with low pollutant concentrations. New microorganisms that are suitable for decomposing naturally occur.
In addition, the spontaneous generation of the microorganisms occurs normally in the natural world, and also occurs in the present invention by the same mechanism. Such naturally occurring microorganisms also contribute to the decomposition and deodorization of odor components. . In addition, there are various types of photosynthetic bacteria and activated sludge bacteria, and effective analysis of the exhaust gas G allows effective bacterial cells to be supported on the filler M during operation of the apparatus.

[0045]

In short, according to the present invention, the internal space of the tower body 4 is divided into an upper deodorizing chamber 6 and a lower dust collecting chamber 7 by a horizontal partition 8, and the deodorizing chamber 6 and the dust collecting chamber 7 are supplied with air. Device 5

Then, the exhaust gas G is sent to the deodorization chamber 6 to perform deodorization processing, and the air is deodorized and exhausted from the exhaust port 21. Can be separated in advance to prevent a failure of the air supply device 5, prevent the dust from flowing into the deodorizing device 1, and prevent the filler M from being clogged by the dust. Further, since the filling material M having the adsorbing property of supporting the microorganisms is filled above the deodorizing chamber 6, the odor component in the exhaust gas G can be removed by the simultaneous progress of the adsorption and the microorganisms. Basically, odor components do not accumulate in the material, enabling continuous operation for a long period of time. Deodorizing room 6
Spray head for spraying make-up water W1U on top of filler M inside
Since 25 is provided, the microbial membrane layer and sulfate ions generated by the reaction mechanism at the time of deodorization can be washed and removed with the replenishing water W1U, and the deodorizing ability can be maintained by eliminating factors inhibiting the microbial reaction. Further, since the dust collecting chamber 7 is provided with a means for separating dust and mist in the exhaust gas G, the exhaust gas source 2
By separating dust and the like from the exhaust gas G sucked from and flowing into the dust collection chamber 7, the exhaust gas G can be purified only by connecting the deodorizing apparatus 1 of the present invention to the exhaust gas generation source 2. In addition, the lower part of the dust collecting chamber 7 is formed as a treatment water storage part 15,
The treated water W2 that has passed through the filling material M can flow freely into the treated water storage unit 15, and further into the treated water storage unit 15, a diluting water system WC for the makeup water W1D and a discharge system WY for the mixed treated water W2Z (discharge water W3). Is provided, the treated water W2 in which the filler M has been washed
Is diluted with make-up water W1D in accordance with the drainage standard and discharged, so that even if the deodorizing device 1 is operated for a long period of time, the pollution of the drainage can be prevented.

Further, a partition plate 22 having air permeability and water permeability is provided above the horizontal partition 8 and a filler M is filled on the partition plate 22 so that the upper partition of the treated water W 2 is filled on the horizontal partition 8. Department
23 and the inflow space 24 for exhaust gas G
Since a drain pipe 26 is provided for communicating the tank body 23 with the treatment water storage section 15, the tower body 4 is divided by the horizontal partition 8 and the partition plate 22 to form the deodorizing chamber 6 and the dust collecting chamber 7, so that the tower body 4 Can be made three-dimensional, and compactness and space saving can be easily achieved.

Further, since the drain pipe 26 is provided so as to penetrate the horizontal partition wall 8, the drain pipe 26 of the washing water (the treated water W2) of the filler M can be arranged in the tower main body 4 to make it compact. .

In the means for separating dust and mist in the dust collecting chamber 7, the exhaust gas G flowing into the dust collecting chamber 7 has a flow path other than a linear flow, and the exhaust gas G flows due to the inertia force of the dust and the mist. G is separated from the exhaust gas G, so that the means for separating dust and mist from the exhaust gas G does not require any driving source, power or special device because the property of the fluid is used. The mist can be semi-permanently separated by collecting the mist in the treatment water reservoir 15 in the dust collection chamber 7.

Further, the exhaust gas introducing duct 10 is installed in a direction above the dust collecting chamber 7 except for the center position and not directed to the center, and the outlet 12 of the exhaust gas introducing duct 10 is connected to the wall surface (inside surface) of the dust collecting chamber 7. (Or outer surface), so that the exhaust gas G can draw a rotating flow in the dust collection chamber 7,
The gas and the mist can be separated from the exhaust gas G by the inertial force, and the intake port 13 of the exhaust gas intake duct 11 is arranged at substantially the center of the upper part of the dust collecting chamber 7, so that the positions of the inlet and outlet are different. In addition, the flow distance of the exhaust gas G required for the separation operation can be secured.

Further, the dust collection chamber 7 is penetrated through the wall of the dust collection chamber 7.
Since the exhaust gas introduction duct 10 is installed inside the exhaust gas introduction duct 10 and the outlet 12 of the exhaust gas introduction duct 10 is arranged at a position facing the inner wall surface of the dust collection chamber 7, the exhaust gas G collides with the inner wall surface of the dust collection chamber 7. Thereby, the separation action can be improved by adhesion to the inner wall surface. Further, since the suction port 13 of the exhaust gas suction duct 11 arranged substantially at the center of the dust collection chamber 7 is directed downward,
The exhaust gas G flowing from the exhaust gas introduction duct 10 and flowing out of the exhaust gas suction duct 11 draws a downward flow and an upward flow, so that it is possible to ensure that dust and mist contained in the exhaust gas G are dropped.

The valve 2 is connected to the water supply system WU from the water supply source PW to the spray head 25 and the water supply system WA to the treatment water storage unit 15.
Since 7 and 27a are provided, use a timer or control device, etc.
The necessary makeup water W1U, W1D can be automatically supplied.

Since a mist remover is provided in the exhaust port 21 of the tower body 4, fine particles of the makeup water W1U containing a water-soluble odor component are generated by the spray head 25 in the deodorizing chamber 6, and the deodorized exhaust gas G The mist, which is fine particles, is removed by a mist remover, and only the gas is passed therethrough, thereby preventing the make-up water W1U containing the water-soluble odor component from being released to the atmosphere. Further, since a deodorizer containing activated carbon is connected to the exhaust port 21, even if the deodorization by microorganisms and the like carried on the filler M is insufficient, the residual odor component from the exhaust gas G released to the atmosphere can be activated carbon. Can be deodorized by adsorption.

The drain pipe 26 provided in the upper stage water receiving portion 23
Outlet of the mixed treated water W2Z (discharged water W
3), the pressure inside the deodorizing chamber 6 is high, while the outlet side of the drain pipe 26 is pressurized by the discharge water W3, so that the exhaust gas in the deodorizing chamber 6 is open. G can be prevented from flowing back into the treatment reservoir 15 and other unexpected flow.

The discharge system WY of the mixed treated water W2Z (discharged water W3) in the treated water storage unit 15 has an overflow system in which the mixed treated water W2Z (discharged water W3) is discharged when the water level is equal to or higher than a predetermined water level. Effluent W3 in the treatment water storage unit 15
, The discharge water W3 can be discharged according to the drainage standard even if the mist and the treated water W2 are mixed or increased. Also, a liquid level gauge 28 capable of measuring the water level of the treatment water storage section 15
Was attached to the treatment water storage unit 15, and it was confirmed by the liquid level gauge 28 that the water level in the treatment water storage unit 15 had risen due to the negative pressure in the dust collection chamber 7,
An appropriate water level can be maintained by reducing the output of the air supply device 5 or by other means.

The adsorbent filler M filled in the deodorizing chamber 6 is a porous material having an average pore diameter of about 100 ° or more. Therefore, it is necessary to increase the ability to retain microorganisms as compared with activated carbon. And the adsorbent filler M filled in the deodorizing chamber 6 includes a porous substance, a substance having a nutrient source, and a nutrient source of microorganisms obtained by granulating and solidifying soil with an adhesive. As it contains the gap between various substances and the water-absorbing substance (soil mainly composed of volcanic ash, etc.), the retention of microorganisms,
It has good water retention and can maintain a growth environment for microorganisms. Activated carbon, which is a typical substance of the adsorbent, is completely carbonized and has a low water retention because its average pore diameter is as small as 10 to 20 mm, and it is difficult to carry microorganisms.
Furthermore, since there is no nutrient source of the retained microorganisms, the microorganisms are difficult to propagate naturally and the microorganisms cannot be sufficiently deodorized.

The filling material M is obtained by steaming an organic substance to form a porous material and soil by using an adhesive to granulate and solidify the substance. The filling substance M is obtained by steaming an organic substance to form a porous material. Because it is made of coal, the same substance as the nutrient source of the microorganisms and the same porous substance can be used to secure a large amount at low cost. Item 15. The filler M according to Item 14, and Claims 15, 16, and 1
Since the filler M of No. 7 is mixed, the practical effect is extremely large, for example, it is possible to select the most suitable filler M for deodorizing power or fluctuation of odor intensity.
