Further, on the exhaust side of the reaction tower f, a filter h equipped with a screw conveyor g at the bottom is connected. To the rear of the filter h, an exhaust fan i and bacon j for exhausting the processing gas are connected through a duct. On the one hand, on the discharge side of the screw conveyor g, a ash removal conveying means consisting of a sliding pipe k, a conveying conveyor m, a bucket elevator η, and the like is connected. -4- The paper standard applies to the Chinese National Standard (CNS) Α4 Specification (210X 297 mm) 496762 A7 B7 V. Description of the invention $), and the ash removal by the filter h will be transported to the chute p provided on the upper part of the combustion furnace a through this ash removal transportation means . (Please read the precautions on the reverse side before filling out this page.) In the waste incineration facility constructed above, remove the soot, acidic and harmful gases, and organochlorine compounds from the following exhaust gases. The fly ash formed by the incombustibles and unburned materials produced by the combustion furnace a, the acidic and harmful gases, and the exhaust gas containing dioxin at about 80 ° C are reburned in the gas mixing chamber b to burn the unburned materials. The fuel is then combusted, and the exhaust gas is introduced into the boiler c. The high-temperature dust collector d in a high temperature zone above 400 ° C is used to filter and remove the fly ash contained in this exhaust gas, and the trace organochlorine compounds attached to the fly ash, most of which will generate dioxin The class was previously thermally decomposed. Next, the above-mentioned exhaust gas that has been treated once is introduced into the reaction tower f, and an alkali agent such as slaked lime slurry sprayed from the sprayer e is used to neutralize the acidic and harmful gas contained therein.

The eighth figure is the same as that shown in FIG. 7 for the device disclosed in Japanese Patent Application Laid-Open No. 10-2 1649, and the same reference numerals are attached, and detailed description is omitted. In FIG. 8, the gas discharged from the incinerator not shown in the figure introduced into the boiler c is cooled in the desuperheating tower u to a temperature suitable for the filter h, and due to the slaked lime on the surface of the filter h described later and The adsorbent is filtered, neutralized, and adsorbed into a tritium gas, and is discharged into the atmosphere from the chimney j. Here, the slaked lime transported from the slaked lime storage chamber v and the sorbent transported from the sorbent storage chamber w are respectively transported by a predetermined amount, and then air-transported by a blower y in the powder mixing device X. And mixed into a mixed powder with a predetermined ratio. This mixed powder will be attached to the filter cloth in the filter h with the exhaust gas blown in. In addition, the exhaust ash swept from the filter h formed by the captured soot and krypton reaction and unreacted powder is usually discharged without treatment together with expensive activated carbon that does not adsorb dioxin. [Problems to be Solved by the Invention] In the conventional waste incineration facility of the former, in the reaction tower f, calcium chloride, which is a reaction product generated by spray, and unreacted slaked lime, are captured by the filter h and returned to The gas mixing chamber b is thermally decomposed in a high tropical zone above 800 ° C, thereby changing into quicklime.

Description of the Invention 4) Residual quicklime reacted with chloride in the body will still be discharged from the recovery ports Q and r to the facility In addition, it reacts with the moisture in the surrounding or ambient gas, creating the danger of high heat. In addition, not only can not save the amount of lime used, but also the dangerous ash removal (discharge of ash) containing heavy metals can not be reduced, that is, the method can save post-processing costs. In the gas mixing chamber b, the organochlorine compound that has been completely thermally decomposed is then re-synthesized between the reaction tower f and the filter h into dioxins, and only neutralizers such as slaked lime are used to respond. Dioxin classes are very limited. Therefore, even if the method of taking out the ash removal to another device for heating is not only expensive in terms of equipment and heating costs, but also because of the unstable temperature, it is difficult to heat the entire ash removal. On the contrary, it has the disadvantage of reducing the dioxin removal rate. . Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs as shown by the two-dotted dotted line, the adsorbent t such as activated carbon is supplied to the upstream side of the filter h, and the dioxin is adsorbed, and the captured by the filter h The entire amount of ash is returned to the gas mixing chamber b for recombustion of unburned materials and thermal decomposition of dioxins. It is also the same as the above, leaving the heat reaction of quicklime, and the amount of medicament and post-discharge treatment. Cost and other issues. If this problem is dealt with, a new problem of complex equipment will arise. On the one hand, in the conventional waste incineration facility of the latter, the exhaust ash formed by the captured soot, plutonium reaction and unreacted neutralizing agent and adsorbent is usually not together with expensive activated carbon that does not adsorb dioxin. The addition and separation are discharged to the outside, which increases the cost of the medicine. At the same time, as the amount of discharged ash is increased, the cost of post-processing is also further increased. Furthermore, not only the heat reduction is increased, but the color of the discharged ash is blackened. The paper size of the combustion confusion applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) 496762 A 7 B7 Printed by the Intellectual Property of the Ministry of Economic Affairs and the Consumer Cooperatives of the Employees 5.

In addition, the operation status of the exhaust gas companion pre-coating method described later, even if the concentration of the acidic and harmful gas at the outlet of the filter device is “far below the specified threshold”, as long as the pressure difference of the filter device reaches the specified threshold, cleaning will be performed. Discharge many unreacted or non-adsorbed medicines. Not only the drug cost is unreasonable, but also the excessive supply of various medicines, which leads to an increase in the amount of discharged ash. 0 It is also due to the different proportions of activated carbon and slaked lime. The distribution of the medicament in the layer is not uniform, resulting in a decrease in the efficiency of the medicament. The present invention is an invention for solving the above-mentioned problems, and an object thereof is to provide a medicine which can suppress waste of medicines, save medicine costs, and can minimize the amount of discharged ash discharged to the outside, thereby saving post-processing costs, and at the same time improving the filtration device.

Description of the invention < 〇) In addition, the filter device 4 is used to capture the soot in the mixed gas 7 8 attached to the filter cloth 41, the carbon-based adsorbent 81 which adsorbs dioxin, and neutralizes the acidic and harmful gases. The neutralizing agent 82 is cleaned from the surface of the filter cloth 41 by the sweeping means 4 3 in the purge gas chamber 44, and becomes ash-removing 83. This ash removal 8 3 is discharged through the classification means 61 1 to remove the incombustible agent 8 4 on the switching conveyor 6 2, and the classified incombustible matter 8 5 is sent to the ash removal treatment means 6 3 (see Figure 1).

Ministry of Economic Affairs Smart Money / i ^ g (Printed by Industrial and Consumer Cooperatives-13-496762 A7 B7 V. Description of the invention) In the system for further reuse of lime, when the neutralization agent is excessive and the reaction efficiency is reduced, the above-mentioned ash removal 8 3 is not used for classification treatment by classification means 61, but is directly used for switching The conveyor 62 is discharged to the side of the ash removal processing means 63 and performs a process including dioxin. Next, the operation conditions of the precoat filter device will be described with reference to Figs. 3 to 6 while comparing the present method with the conventional method. Fig. 3 is a graph showing the pressure difference and the concentration of harmful gas when the filter bag is cleaned and each medicine is supplied when the method of the present case is used. Fig. 5 is a cross-sectional view showing the state of adhesion of various substances to the surface of the filter cloth when using the method of the present case, and Fig. 6 is a diagram showing the surface of the filter cloth when using the conventional method. Sectional view of the adhesion of each substance. First, in the conventional manner shown in FIG. 4, as long as the filtering pressure difference is close to the prescribed threshold, each unit's dust collection mechanism sequentially sweeps the attachments on the surface of the filter cloth, returns the pressure difference to the original point, and simultaneously cleans the filtered filter. On the cloth, the mixture of slaked lime, calcium carbonate, etc., which is accompanied by the exhaust gas, and the adsorbent and powdered activated carbon, etc., and a mixture of auxiliary agents are added in a sufficient amount (for example, all the unit dust collection units are 1 hour) Once supplied and a pre-coat layer is formed (see Fig. 6), the supply of the drug is stopped, and it is transferred to a normal filtration operation including a neutralization and an adsorption reaction. With the continuous accumulation of soot from this filtering operation, the pressure difference will gradually rise. When the specified threshold is reached, the above-mentioned cleaning operation will be returned. However, due to the large change in the concentration of harmful gases, too much attention is paid to reducing the maximum threshold. There is a tendency to oversupply the neutralizing agent. As a result, the differential pressure rises faster. This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm). -14-(Please read the precautions on the back before filling (This page) •• Order the Intellectual Property of the Ministry of Economics ¾ Printed by the Employee Consumer Cooperative 496762 A7 B7 Printed by the Intellectual Property of the Ministry of Economic Affairs Goubei Gong Consumer Cooperative V. Invention Description t2) Even if the concentration of harmful gas is far below the emission limit, except In addition to the pre-coated acidic and harmful gases, calcium chloride and tritium adsorbing dioxin-type activated carbon, unreacted slaked lime and activated carbon with excess adsorption capacity will also be swept away with the soot layer growing on the surface, making it expensive. The medicine was discharged without being used. In order to solve this problem, the method shown in Fig. 3 is to remove the necessary amount of carbon-based adsorbent 81 according to the past actual performance and experience of the plant and supply it to the exhaust gas together. On the filter cloth, next, check the concentration of the harmful gas at the outlet of the filtering device 4 to neutralize the medicament 8 2 to a degree of half, and also attach it to the carbon-based adsorbent 81 at one time with the exhaust gas to form a precoat layer ( All of the plural unit dust collection mechanisms are, for example, 40 to 50 minutes). Here, the specific gravity of the carbon-based adsorbent 81 is light, and the specific gravity of the neutralizing agent 82 is heavier. Compared with the mixed spraying method of the conventional method, each layer can be adhered uniformly. Next, transfer to the filtering operation through this pre-coating. As described above, the amount of the neutralizing agent 82 is small, and the thickness of the pre-coating is very thin. Although it has the advantages of light ventilation equipment load and slow rise of pressure difference, But harmful gas concentrations have risen quickly. Therefore, to grasp the degree of increase in the concentration of harmful gases, in contrast, the stored medicament 8 4 should be intermittently added to the recombustion chamber body 2 2 at appropriate intervals until the pressure difference limit is reached, thereby, The calcium chloride reacted by the radon in the agent 84 is converted into quicklime, and passed through the high-temperature flue 26, the medium-temperature flue 35, and the like, and sent to the filtering device 4 to form a layer of the agent 84 to maintain the neutralization performance.

Description of the invention < 3) By repeating this additional supply, when the pressure difference rises to the specification Alas, it will return to the initial cleaning. (Please read the precautions on the back before filling this page.) The reason for this series of operations is because a simple device can continuously obtain the radon concentration of harmful gases. Based on this concentration, appropriate amounts of neutralizing agents 8 2 and 8 are supplied. 4, to prevent the discharge of unreacted slaked lime, but the analysis of dioxin concentration takes a long time and is not suitable as a control target parameter. Therefore, based on the past actual results and experience of the plant, the supply amount of carbon-based adsorbent 81 must be set first. Use the full supply as efficiently as possible, and then use the additional supply of combustion air 7 3 or the water spray device 1 4 to fine-tune the cooling in the furnace according to the C 0 concentration as the dioxin concentration reference 値 (see Figure 2) . In addition, although it has been explained that the supply of the neutralizing agent 82 is only in the initial stage when the precoat layer is formed, the agent 84 is supplied as an additional supply, but the order may be changed or the neutralizing agent 82 and the agent 84 may be sprayed simultaneously.

The treatment method is to make a predetermined amount after cleaning The carbon-based adsorbent adheres to the surface of the filter cloth in one fell swoop, and then sprays a smaller amount of a neutralizing agent onto the surface of the adsorbent layer at an initial stage, thereby forming a pre-coating layer. After that, it continues to run until Until the pressure difference reaches the specified threshold, at least a part of the freshly neutralized medicine or the ash removed will be thermally decomposed with recombustion equipment. One of the generated medicines is determined by the acidic and harmful gas concentration at the outlet of the filtering device. The determined quantity will continue to increase r supply, and the Chinese national standard (CNS) A4 specification (210X297 mm) will be applied to the paper size.

Body 'and the adsorbed dioxin harmless thermal decomposition, agents may also be recycled by thermal decomposition. In addition, carbon-based adsorbents that can effectively use up expensive activated carbon and the like are complementary to the reuse of supplying only a necessary amount of a neutralizing agent, thereby saving the cost of medicine. As a result, the amount of ash discharged to the outside is minimized, and post-processing costs can be saved. In addition, the carbon-based adsorbent with a light specific gravity can be attached in advance to make the thickness of the precoat layer uniform, thereby improving filtration, neutralization, and adsorption efficiency.
