 The present invention relates to a continuous pyrolysis method and apparatus for waste containing organic matter and an i-cracking gasification system. More specifically, the present invention relates to a sealed chamber in which a pyrolysis heating section is formed so as not to always exceed atmospheric pressure.

 : The critical oxygen concentration is the minimum oxygen concentration required to continuously burn or explode combustible materials. If the oxygen level is less than this value, the combustion or combustion explosion of combustible materials does not occur as in the case of the oxygen-free state. Therefore, in the present invention, the state below this limit oxygen concentration is called the oxygen-free state.

 As it is clear from the following known examples, “thermal solution” means that when a combustible is normally heated at about 5 0 0 to 6 0 0 ° p with outside air blocked, the thermal decomposition reaction is promoted, It can be made into pyrolysis gas and residue without burning or burning. It is a so-called steamed and burned state of combustible material. Pyrolysis reaction, the heat furnace is heated using a method such as heating the outer jacket of a kiln or other furnace with a gas burner or the like, or delivering high-temperature air to the outer circumference. Heat itself and heat the furnace in the out-of-air condition. It can be realized by heating to about C. In addition, ripening using electromagnetic induction is called induction heating or electromagnetic induction heating. The principle is> When an alternating current is passed through a conductor, magnetic lines of force are generated around it. An eddy current flows through a conductive material such as a metal that is coiled along a center line, and Joule heat is generated by the electrical resistance of the conductive material, which heats the metal itself. There is also a method of adopting this principle to form a heat-heating part made of a conductive material, in which a combustible material is thermally decomposed in an oxygen-free state.

Municipal waste, industrial waste, especially medical waste, etc. contain organic materials. Combustion in an incinerator or the like can generate chlorine gas and unacceptable dioxin. Incineration of 1 9 9 4 牟 H¾ Ash special management waste designation and environment such as 1 9 9 7 secondary dioxin control guidelines 30. With increasing regulations on pollution, for example, In a medical institution The current situation is that the incinerator is closed or discarded, and the plastic container containing the medical waste is collected and processed by the medical waste disposal contractor. For this reason, a technique and a system or the like for pulverizing a plastic container and performing sterilization treatment by high-frequency heating or the like to perform landfill or compression decomposition after compression packaging have been put into practical use.

Regarding the prior art, Japanese Patent Publication No. 7-3 2 3 2 70 discloses that the opening is material-sealed by pyrolyzate, and the heating envelope that follows the hermetic pyrolyzed soot. The gas burner is equipped with a device that heats the pyrolysis soot to 2500-500 ° C and pyrolyzes the waste inside. Similarly, the device described in Japanese Patent No. 3 3 7 7 3 9 supplies hot air generated by an air heater in a combustion melting furnace provided on the downstream side of a laterally-oriented ripening drum to the outer periphery of the heating drum. '' Pyrolyzes the combustibles in the ram, and has the feature that the heated drum is held near the atmospheric pressure in a low oxygen state by the introduction of an inert gas instead of air. . Next, regarding the pyrolysis method and equipment for waste by electromagnetic induction heating, the publication of Japanese Patent Laid-Open No. 10-4 3 7 1 4 discloses that each container is filled with waste. It is inserted into an electromagnetic induction heating source to completely block out the outside air and make the waste steamed, so that the chlorine component in the waste can be extracted effectively. Yes. Japanese Laid-Open Patent Publication No. 20.3-1 4 2 16 relates to an electromagnetic induction heating drum for a heat reaction caused by electromagnetic induction heating. It is described that the air is evacuated by the suction of the evacuation pump, is brought into a nearly vacuum state (oxygen-free atmosphere), and the waste is pyrolyzed with a drum Λ heated with juicy heat. Specifically, heating '. The drum is provided with a sealable shutter at each of the waste intake and exhaust, the outlet, and the pyrolysis gas exhaust hole to prevent inflow of air from outside the drum. The inside of the drum is kept in a gas state, and the waste product that has been input is transported by a screw conveyor and can undergo a thermal decomposition reaction in an oxygen-free state. A double shutter device that can be opened and closed alternately, and an air vent for lowering the internal pressure are provided separately. Patent documents of the same series include Japanese Patent Application Laid-Open No. 2 0 0 5-1 2 7 6 8 0, Japanese Patent Application Laid-Open No. 2 0 0 5-1 2 7 6 8 2, and Japanese Patent Application Laid-Open No. 2 0 0 4-2 9. 3 3 9 publication. The electromagnetic induction heating device disclosed in these licensed documents has a structure in which a crushing / drying unit, a heating unit, and a cooling unit are arranged in front and behind a single drum-shaped combustion chamber, or each unit One of the structures is a structure in which a plurality of horizontally-facing drum combustion chambers having intakes and discharge ports are provided in the front, and the discharge ports of the front combustion chamber and the intake ports of the rear combustion chamber are detachable. In the latter case, any structure can be used as long as the preheating process and the postprocessing cooling process are used to carry in and discharge the combustibles into the induction heating unit. at least The electromagnetic induction heating unit has an outer wall covered with a heat insulating material and Z or a water jacket, and the surrounding wall is coiled with a conducting wire through which an alternating current flows. It is a horizontal drum-shaped combustion chamber structure made of a conductive material provided at least at the end, and can be freely rotated around an axis as necessary. In addition, a screw conveyor can be used to enhance the stirring function of the combusted material in the combustion chamber, and a stirring battle can be arranged on the rotating shaft, or a cork screw blade can be arranged on the inner wall of the drum.

Next, there is a method and apparatus for replacing inert gas (or fluid) in a heating ram and maintaining airtightness described in 'JP 2 085-8 3 7 1.8'. As can be seen, the burned material is placed in a heating cylinder arranged in a sealed chamber having an openable / closable sealing lid that completely shuts off the atmosphere as described in JP-A-10-4 3 7 1 3 above. Dispose of the combusted material that has been treated as chlorine or a chlorine compound without gasifying the chlorine component contained in the combusted material by steaming the combusted material by electromagnetic induction heating in the heating cylinder. ¾ Similar to the method, the top cover and bottom cover are alternately used in place of the openable / closable sealing lid so that the batch processing by electromagnetic induction heating of the combusted material can be performed efficiently while blocking the atmosphere. An open hopper for combustibles with a double shutter that can be opened and closed freely, and for burning combustibles So as not to burn or combustion explosion Nau combustible gas, a method of replacing the 'inside of the input hopper and dense closed from the inert gas atmosphere is disclosed. The disclosed equipment has an injection hopper, a sealed chamber, and heating cylinders arranged in the sealed chamber arranged in a vertical shape. Valves are connected to each other by pipes from an inert gas storage tank provided outside them. It is possible to adjust the 'active flow rate' through the. Physically, the inert gas is communicated from the inert gas storage tank through the valve to the charging hopper and the sealed chamber. The gas generated from the combustible gas in the charging hopper and closed chamber communicates with the exhaust gas treatment facility via each valve and is discharged. At that time, flammable gas is generated, so an oxygen concentration sensor is placed in advance in the charging hopper and the sealed chamber, and the replacement state of oxygen (atmosphere) and inert gas such as nitrogen (N ₂ ) is always maintained. It can be monitored. Furthermore, in this document, the amount of generated gas increases as the combustion temperature of the combusted material increases, but it is not possible to keep the sealed chamber at a pressure slightly higher than the atmospheric pressure in order to suppress the inflow of air into the sealed chamber. It is also disclosed that the flow rate of the active gas is increased at the initial stage so that the flow rate can be met with a small flow rate as the amount of generated gas increases. However, such treatment in the sealed room must be released and set repeatedly each time. By the way, various methods and apparatuses have been proposed in addition to this for the formation of a combustion environment of waste by an inert gas. For example, as described in JP-A-6-2 8 1 3 6 2, heat treatment such as reflow in semiconductor manufacturing is .

This is a treatment in an inert gas atmosphere furnace, and a method is adopted in which a gas film containing an inert gas is formed at the inlet and outlet of the workpiece to completely block the atmosphere inside and outside the furnace. Among them are those described in Japanese Patent No. 2 6 3 5 4 5 9 that include a double gate that forms an inert gas film at a certain distance at each of the entrances and exits. . In addition to the above, as a proposal regarding an apparatus that always encloses with an inert gas in an incineration processing apparatus for an explosive or flammable processing object, the above-mentioned Japanese Patent No. 3 3 7 7 3 59 and Japanese Patent Laid-Open No. 20-320 No. 5-2 0 7 6 8 4 can be mentioned. In particular, the latter includes treatment of medical waste that is very difficult to handle, for example, so that the waste is not exposed to the atmosphere or the worker is not likely to come into contact with it.

 In addition, as a proposal for a pretreatment method and apparatus for burned flames disclosed as a medical waste treatment method and an optoelectronic device, Japanese Patent Publication No. 20.2-5. 1 6. 7 20 It is a medical waste treatment in a fully equipped laboratory where the entrance / exit is completely shut off from the atmosphere by using multiple airlocks, even with prior powder and Z or heat treatment. Also. The document also discloses a large fan device equipped with an air filter that keeps the processing chamber in a negative pressure state so that the polluted air generated by the heat treatment does not leak and Z ′ or backflow.

(Patent Document 1 2) Special Table 2 0 0 2 1 5 1 6 7 2 0 Publication When organic waste is burned and heated in an incinerator, the generation of toxic gases such as pollutants and dioxin is avoided. Absent. To remove pollutants and control toxic gas emissions One of the solutions is the development of a method and apparatus that enables thermal decomposition in the absence of oxygen. As a result, generation of toxic gases including carbon monoxide and dioxin can be suppressed, and at the same time, contaminants such as viruses and pathogenic bacteria can be removed. However, the formation of anoxic conditions is not easy. It has been proposed to form a heat chamber for waste containing organic matter in a vacuum or almost vacuum state by venting, or to introduce an inert gas or the like into the formed vacuum or almost vacuum state. The technical challenge of creating a pyrolysis chamber for organic-containing wastes in a vacuum or almost vacuum is to put the processing chamber in a negative pressure environment. A complete shielding means must be adopted at the point of contact with the atmosphere such as the exhaust vent. .

The inside of the heating device must be completely isolated from the atmosphere by means such as mechanical shutter, air lock or air shutter, material sealing, and replacement with inert gas such as nitrogen (N ₂ ). Is extremely difficult and more complete. If you want something, you have to be expensive. Therefore, as a next best measure, in mechanical and pneumatic means ... Double inert, simply inert that does not include the fact that the inside of the inner gas has a gradient of inert gas higher than atmospheric pressure. Examples thereof include a gas atmosphere forming method. .

 A further technical challenge is to prevent leakage and / or backflow of pyrolysis gas generated by pyrolysis. Leakage of pyrolysis gas generated from the pyrolysis reaction of waste containing organic substances and prevention of Z or backflow are considered from the viewpoint of contamination from organic substance-containing waste management methods or leakage of poisonous gas from the treatment room. It is one of the important technical issues. For this reason, most of the conventional technologies usually create a negative pressure in the room while maintaining the sealing of the entrance and exhaust holes! Thus, this technical challenge has been overcome. However, the formation of such a chamber in a negative pressure state has the problem that it becomes difficult to completely block the inflow of air by placing the pyrolysis chamber of organic-containing waste in a negative pressure state as described above. Will also face. It is necessary to solve these two issues in a trade-off relationship at the same time.

The next technical problem is to prevent the deterioration of the equipment function due to melting and Z or viscous adhesion temporarily generated during the heat treatment process of organic material-containing waste containing polymer materials. For example, in the case of thermal decomposition or combustion treatment that includes a pre-process of crushing plastic containers filled with organic matter-containing waste such as medical waste treatment, combustibles containing large amounts of polymer materials are exposed to high temperatures. Because it is transported through the horizontal drum-shaped heating chamber to the discharge port in a state of containing the molten high-viscosity polymer material, the viscous polymer material melted on the screw conveyor that is normally adopted as the transport means It is inevitable that adhesion accumulates. This avoids degradation of device functions -If you try to do so, you have to stop the entire system quite often and disassemble and clean the combustion chamber and the screw conveyor itself.

 The question is how to maintain the continuity of the thermal reaction of organic waste. In particular, when an inert gas atmosphere is formed and a large amount of waste containing organic substances is to be processed, continuous processing must be assumed during normal operation except during startup. However, no means has been proposed to realize continuous processing during normal operation while solving the technical problems as described above, and such proposals could be awaited. + '■' .. Disclosure of the Invention '.

 The solution to the above-mentioned problem is thermal decomposition in which organic-containing waste introduced from the upper side is thermally decomposed, pyrolysis gas generated from the downstream side is exhausted, and residual carbides are discharged. Use an inert gas injection means to feed the inert gas into the sealed chamber where the heating section is formed between the upstream side and the downstream side. And the outside air is shut off to make the sealed chamber oxygen-free, and the inert gas flows from the upstream side to the downstream side of the sealed chamber so as to exceed the gas pressure of the generated pyrolysis gas. Forming a pressure gradient and causing the pyrolysis gas to flow backward from the downstream side to the upstream side: The organic waste containing the waste is continuously pyrolyzed so as to be exhausted from the sealed chamber. It can be achieved by the present invention. .

 In other words, a positive pressure state with an inert gas is formed in the sealed chamber, which prevents the atmosphere from entering the sealed chamber in an oxygen-free state, and makes the sealed chamber inactive. The gas pressure of the gas always exceeds the gas pressure of the pyrolysis gas generated by pyrolysis,

P _N > P _G ≥ P _H > P ₀ ... (2).

That is, the gas pressure P of the inert gas upstream of the closed, closed chamber P: _N and the mixture of inert gas and pyrolysis gas in the pyrolysis heating part ^ S pressure P _G and mainly the pyrolysis gas downstream.

As the atmospheric pressure always exceeds the atmospheric pressure, the outside air is shut off and the sealed chamber becomes oxygen-free, and the gas pressure of the generated pyrolysis gas is also exceeded from the upstream side to the downstream side of the sealed chamber. A pressure gradient is formed, and the heat component gas is recovered from the sealed chamber without flowing backward from the downstream side to the upstream side. In addition to the features of the invention described in claim 29, the invention described in claim 30 includes a conductive material in which a pyrolysis heating portion is wound by an electromagnetic induction coil, and an outer wall ^ It is characterized by having a heat insulation structure and covering with a water jacket through which the refrigerant circulates.

(1) In the method and apparatus and the pyrolysis gasification system that enable continuous pyrolysis of organic-containing waste such as medical waste, the sealed chamber having the pyrolysis heating section is not evacuated. An inert gas is sent at a pressure always higher than the atmospheric pressure, and an inert gas pressure gradient is formed from upstream to downstream of the sealed chamber, so that an oxygen-free state in the sealed chamber can be easily formed. That is.

(2) This prevents the outside air from flowing into the sealed chamber having the pyrolysis heating section and induces combustion or combustion explosion, and uses the pressure gradient of the inert gas to perform pyrolysis. This ensures that the pyrolysis gas generated in this way can be reliably exhausted from the downstream exhaust hole without backflow. . (3) In addition, by using a pusher plate with a shape that roughly matches the cross-sectional shape of the sealed chamber, the organic material-containing waste is pyrolyzed in the sealed chamber ^ This is to prevent the deterioration of the apparatus performance due to melting and Z or viscous adhesion temporarily generated during the waste treatment process.

-(4) Furthermore, by controlling the amount of inert gas fed in while monitoring the inert gas pressure in the sealed chamber, it has become possible to perform continuous pyrolysis treatment of a large amount of organic waste.

 (5) Furthermore, the pyrolysis gas and residual carbides produced by the continuous pyrolysis of waste containing organic matter can be recovered and recycled without 'polluting'. . 'Simple drawing | ¾description';. ■, '.

Therefore, if necessary, it is possible to attach a detachable scraping claw 5 1 2 that scrapes off deposits on the inner wall of the sealed chamber 3.

The above-described inert gas injection device 6 is a tank that stores a gas such as nitrogen (N ₂ ) or argon (A r). 'With the pipe having the valve, the inert gas is fed through the inert gas inlet 61 on the uppermost stream side of the sealed chamber 3 and the pipe having the pulp also in the transfer chamber 42 described above. It is also possible to send an inert gas through the inert gas inlet 6 2. : When the inert gas is fed into the sealed chamber 3, the reciprocating motion of the pusher plate 51 also causes a communication device 5.2 comprising the communication hole 5 1.1 provided in the pusher plate 51 to Thus, an inert gas can flow in and out, and an inert gas pool or an inert gas atmosphere 63 can be formed and maintained in the sealed chamber 3.

Normally, a shutter device for preventing the inflow of outside air is appropriately provided in the vicinity of the exhaust hole 71 and the exhaust outlet 8.1. As will be described later, one of the features of the present invention is as follows. Such a device is not necessarily required.

The pyrolysis heating unit 31 by electromagnetic induction is formed between the upstream side and the downstream side of the sealed chamber 3. As shown in Fig. 3, the pyrolysis heating unit 3 1 consists of a cylindrical container ³ 1 1 made of a conductive material that generates heat by electromagnetic induction heating, and its outer periphery is covered with a heat insulating material 3 1 '2. The coil support members 3 1 4 provided on both ends of the outer periphery of the cylindrical container 3 1 1 can support the electromagnetic induction heating coil 3 1 3 wound around the outer periphery of the heat insulating material 3 1 2 . In addition, a cooling pipe in which coolant such as cooling water circulates on the electromagnetic induction heating unit 3 1 3 (referred to as “water jacket”) 3 '1 5 is wound, and the cooled cooling pipe 3 .1 A support member 3 1 6 is provided to support 5 in the longitudinal direction of the cylindrical container 3 1 1. Although not shown, ^ ^retirement: cooling Bruno drive 3 1 5 'to the supply pump device and providing the high frequency power source for supplying a current to the electromagnetic induction coil 3 1 3 course water. 3. The high frequency power supply connection terminal position 3 17 shown in FIG. 3 is the terminal position with the electromagnetic induction coil 3 13. In addition, as is apparent from FIG. 3, the cylindrical container 3 1 1 is connected to the electromagnetic induction coil 3 for cleaning the inside of the sealed chamber 3 by releasing the coil support members 3 1 and '3.16. It is also possible to design it so that it can be divided into 1 and 3 in two. Mounting bolt position 3 1 8 is the joint between the cylindrical vessel 3 1 1 and the upstream side of the sealed chamber 3, and mounting bolt position 3 1 9 is the joint between the cylindrical vessel 3 1 1 and the downstream side of the sealed nitrogen 3. Although these are the parts, these may be integrally formed in a sealed chamber. In order to adjust the internal temperature of the cylindrical container 3 1 .1 by measuring the temperature of the cylindrical volume ³ 1 1 by electromagnetic induction heating and controlling the voltage to the high frequency power supply of the electromagnetic induction coil 3 1 3 A thermocouple temperature sensor 3 2 0 penetrating the material 3 1 2 can be appropriately provided in the cylindrical container 3 1 1. The pyrolysis heating unit 3 1 is composed of a cylindrical container 3 1 1, a heat insulating material 3 1 2 and a water jacket 3 1 5, so that the cylindrical container 3 1 1 is electromagnetically induced from 5 0 0 to 1 0 0 0 Even when heated to ° C, the outer peripheral temperature of the pyrolysis heating unit 31 can be kept at about 40 ° C, so combustion or even combustion explosion due to inflow of outside air into the cylindrical container If it can be controlled, there will be no operational safety or fire hazard.

By configuring the sealed chamber 3 as described above, the gas pressure of the inert gas sent using the inert gas injection device 6 is set to exceed at least atmospheric pressure, the outside air is shut off, and the sealed chamber 3 is Anoxia can be achieved. Furthermore, it is generated by thermal decomposition in the sealed chamber 3 and gradually increases. The gas pressure of the pyrolysis gas and the gas pressure of the inert gas sent from the upstream side of the sealed chamber 3 are balanced from the upstream side of the sealed chamber 3 so that they are balanced at least downstream of the sealed chamber 3. A pressure gradient of the inert gas to the side is formed, and the pyrolysis gas is exhausted from the sealed chamber 3 without backflowing from the lower side to the upper side. The amount of feed can be controlled. More specifically, the continuous pyrolysis of the organic matter-containing waste 1 put into the sealed chamber 3 and sequentially sent to the pyrolysis heating unit 3 1 is performed by the inert gas injection device 6 inside the sealed chamber 3. Gas pressure of inert gas sent to the tank: P always exceeds the atmospheric pressure P ₀ , '..'.

P〉 P (1). '--In other words, a positive pressure state due to the inert gas is formed in the sealed chamber 3, thereby blocking the inflow of air to the sealed chamber and making it non-acidic. The gas pressure of the inert gas in the sealed chamber always exceeds the gas pressure of the pyrolysis gas generated by pyrolysis,

P _N > P _G ≥P _H > P o '' (2),

 'In other words, the gas pressure PN of the inert gas upstream of the sealed chamber 3 PN and the mixed gas pressure of the inert gas and pyrolysis gas of the pyrolysis heating unit 3 PG and mainly the pyrolysis gas downstream , Gas pressure P.H, but atmospheric pressure P.H. This creates a pressure gradient of inert gas that exceeds the flow rate, which prevents the backflow of pyrolysis gas from the downstream side to the upstream side in the sealed chamber. The exhaust can be recovered. ^.

Next, the generated pyrolysis gas is recovered by the exhaust recovery device 7 through the exhaust hole 71. More specifically, the air is turned ι. The heat generated by the gas pressure of the inert gas in the sealed chamber 3 ^{1. The} decomposed gas passes through the exhaust hole 71 and the gas induction pipe 72 and is cooled by cooling water at the outer periphery. It is sent to the oil and water device 7 4 via the cooling device 7 3. 'Here it is separated into oil and water, then by the exhaust fan 7 6', the residual pyrolysis gas is sucked from the oil / water separator 7 4 to the mist separator 7 '5 and then washed here Exhausted outside. The liquefied product separated by the oil / water separator 74 and recovered by the recovery device has a calorific value similar to that of heavy oil, and can be reused as fuel for the drying device described above, for example.

The residual carbides from the pyrolysis reaction are recovered by the discharge device 8 via the discharge port 8 1. The discharge device 8 includes a horizontal cylindrical cooling device 8 2 and a container type recovery device 8 3. Cylindrical cooling device 8 2 has an upstream side that is connected to discharge port 8 1 of sealed chamber 3. It is designed to be discharged from the discharge port 8 2 2 provided on the side to the container type recovery device 8 3. Residual carbides are scattered .

 Since it tends to become dusty, it is preferable to provide a confidential shutter at the outlet 8 22 or the inlet of the container-type collection device 8 3 in order to prevent such scattering. By the way, it should be pointed out that the recovered carbide has a calorific value similar to that of coal, and can be recycled as solid fuel.

The temperature of the pyrolysis heating unit 3 1 is set to 85 ° C., and as shown in FIG. The waste-containing waste 1 that has been transported is temporarily retained by reaching the transport chamber 4 '2 in which the upper shirt is open and the shutter is closed. An inert gas is sent through an inert gas inlet 62 connected to the transfer chamber 42. The inactive gas sent in passes through the upper shutter in the open state and flows into the sealed conveyance path 2.

 Similarly, the inert gas force S is sent to the sealed chamber 3 via the inert gas injection 61, and the sent inert gas is sealed by the communication device 5 2 consisting of the communication holes 5 1 1 to 15. It flows into the downstream side of the chamber 3 and expels the air in the sealed chamber, and an inert gas atmosphere is formed inside the sealed chamber. Next, the upper stage of the transfer chamber 4 2 is closed and the lower stage shutter is opened. T Inert gas sent from the inert gas inlet 6 2 flows into the sealed chamber 3 of the inert gas atmosphere. Inert gas'. A puddle is formed. The accumulated organic matter-containing waste 1 is put into the inert gas reservoir formed in this way. The introduced organic matter-containing waste 1 is sent to at least the pyrolysis heating section 31 by the forward stroke of the pusher plate 51 of the reciprocating device 5. .

Organic waste containing ^: sent to the pyrolysis heating section 31 of the sealed chamber 3 undergoes a pyrolysis reaction in the pyrolysis heating section at 85 ° C. Here, the plastic contained in the organic matter-containing waste 1 becomes pyrolysis gas, and paper and fibers become carbide. As shown in Fig. 2, the upper shutter of the transfer chamber 4 2 was closed and the lower shutter was opened in an inert gas pool or inert gas atmosphere in the sealed 25 chamber 3 until the thermal decomposition reaction occurred. At that time, the gas pressure of the inert gas in the transfer chamber 42 is sent via the inert gas inlet 61 by the inert gas sent via the inert gas inlet 62. The gas pressure in the closed chamber 3 of the inert gas atmosphere formed by the inert gas is exceeded. Gas pressure sensors 6 4 1 to 6 4 4 so that the pyrolysis reaction starts in the pyrolysis heating section 3 1 and always exceeds the gas pressure of the pyrolysis gas that is generated. ■

The gas pressure in the sealed chamber 3 is monitored using the, and in conjunction with each other, the inertness is controlled. The amount of inert gas delivered from the gas injection device 6 to the sealed chamber 3 is controlled. . This makes it possible to ensure that the gas pressure inside the sealed chamber 3 always exceeds the atmospheric pressure, and at the same time forms a pressure gradient of the inert gas from the upstream side to the downstream side of the sealed chamber. It's also possible.

 Organic matter-containing waste 1 sent via the closed transfer path 2 is partitioned by the two-stage shutter device 4 3. The transfer chamber 4 2 is put into the closed chamber 3 sequentially while staying temporarily, The organic material-containing wastes 1 that are sequentially fed are sequentially fed to the decomposition heating unit 31 of the sealed chamber 3 by the reciprocating motion of the pusher plate 51 of the reciprocating device 5. The generated pyrolysis gas is surely sent into the exhaust hole 71 due to the pressure gradient of the inert gas formed inside the sealed chamber 3. Residual carbides can also be discharged by extending the forward stroke of the pusher plate 52 to the vicinity of the discharge port 81, for example. In addition to this, it is also possible to provide a separate discharge device.

 According to the present invention, as apparent from the operation procedures shown in the embodiments and flowcharts, the above-described effects are exhibited. In addition, waste containing organic matter can be continuously thermally decomposed with almost no air pollutants, and the heating temperature can be adjusted according to the nature and type of treatment ^ ;. is there. : ■
