Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for appropriately treating a combustion product generated when a product is burned while preventing or suppressing the generation of pollution. The invention therefore belongs to the technical field for treating combustion products. The present invention is also a pollution control technology.

[0002]

2. Description of the Related Art In recent years, environmental problems (eg, air pollution, traffic problems caused by garbage trucks, odor pollution, generation of pests, etc.) in areas that have garbage disposal sites, and disposal sites (disposal sites) caused by location problems A variety of waste-related issues are occurring simultaneously, such as an absolute shortage, garbage acceptance limits, and rising disposal costs. This has already been pointed out as a social problem.

[0003] Looking at the construction work of buildings and the like from this viewpoint, wood pieces, corrugated cardboard, paper, cloth, plastics (resin tile, vinyl, foamed styrene, etc.), electric wires, new building materials, and other construction waste materials are considered to be skeleton works. Since then, a large amount has been generated until completion. Moreover, in a construction site where the number of workers is more than 100, the amount of lunch shell alone becomes enormous. These solid wastes are almost difficult to dispose in large quantities because of their great impact on the environment around the site. This is especially the case in urban areas. Therefore, many solid wastes generated in large quantities from construction sites are handled by contractors, who transport them to treatment sites (disposal sites) and treat them here. However, such waste treatment has been pointed out as described above.

[0004] Under such circumstances, there is an urgent need to take effective waste treatment measures even in the construction industry where a large amount of solid waste is generated. "Reuse" as part of that
The company has implemented measures to reduce the amount of waste generated, such as "recycling (separation)" and "elimination of excess packaging." The "volume reduction" that is pushing this further is also being promoted. This volume reduction is a coined word meaning that the volume of solid waste is reduced by a method such as compression, crushing, cutting, or incineration. Incidentally, assuming that the volume of solid waste before volume reduction is V ₁ and the volume of solid waste after volume reduction is product V ₂ , the volume reduction rate V (%) of solid waste is V (%) = (V ₂
÷ V ₁ ) × 100. Reducing the volume of waste reduces the cost of processing and transporting waste, and also extends the life of a disposal site (disposal site). By the way, at civil engineering work sites and building demolition work sites, concrete shells are shattered and reduced in volume to be reused as substitutes for gravel. It is practiced to reuse the fertilizer for organic fertilizer.

[0005]

The above-mentioned reuse, recycling, abolition and volume reduction of excess packaging reduce the amount of solid waste generated and reduce the volume of generated solid waste. The above is valid. However, construction sites in congested areas such as urban areas cannot be reduced in volume due to lack of space, pollution, and other restrictions. So, what is the current situation? Since only volume reduction of “garbage burning” using a small-scale combustion furnace has been carried out, the volume reduction effect cannot be greatly expected. Even if pollution problems are cleared by established means, there are still many issues to be solved, such as space saving, resource saving, automation (reduction of personnel), and reduction of processing costs.

On the other hand, the waste incineration method, which is widely used as a classical means for reducing the volume of the waste, is considered to emit harmful substances represented by dioxin and the like into the atmosphere at a level higher than the standard value. It is a big social problem. This has forced many of the existing facilities to suspend their use, forcing new measures to be taken. But there are huge costs to take new measures. This puts economic pressure on cleaning authorities and private processors,
It has made garbage disposal even more difficult.

[Object of the Invention] The present invention has been made to solve such technical problems. In other words, the present invention relates to the technology of burning objects and the technology of treating the combustion products generated at that time, which suppresses or prevents the occurrence of pollution, saves space, saves resources, automates, reduces processing costs,
An object of the present invention is to provide a method and an apparatus capable of satisfying valuable waste treatment of solid waste and large volume reduction of solid waste.

According to a ninth aspect of the present invention, there is provided an apparatus for treating combustion products according to the eighth aspect, wherein a vertical cylindrical casing and a vertical casing disposed at a central portion in the casing are provided. The crusher is characterized by comprising a rotating shaft and a plurality of articulated strips radially attached at one or more stages around the rotating shaft.

[Action] As is obvious, when combustibles are burning in the combustion furnace, combustion products such as smoke gas and ash are generated in the combustion furnace. The smoke gas at that time contains soot and fly ash. Some or all of these combustion products are harmful and cannot be released directly to the outside.

In the method for treating a combustion product according to the first aspect of the present invention, the combustion product in the combustion furnace is poured into a merging pipe where a liquid jet (jet) is generated. In such a case, the smoke gas or ash collides with the liquid having high flow energy.
Smoke fine particles having strong water repellency, such as carbon, soot, and fly ash, contained in the smoky gas are adsorbed by the jet while being struck by the jet with increased affinity for the liquid. Ash with high water repellency also has an increased affinity and is adsorbed by the liquid. In addition, dioxins, heavy metals and other harmful components are also washed away from the smoke gas. The advantage of the treatment using the liquid jet is that a high adsorption treatment effect and a high cleaning treatment effect are obtained, which is also desirable in that it also serves as a means for transferring smoke gas and ash. In the confluence pipe in this case, an adsorbed liquid such as mud in which the jet liquid and various kinds of fine particles are mixed is generated, and the gas in the smoke gas is mixed therein. When these adsorbing liquids and gases flow into the precipitation tank from the merging pipe, fine particles in the adsorption liquid precipitate in the precipitation tank or gas is discharged out of the precipitation tank. The gas discharged to the outside from the settling tank contains almost no harmful components even if it is after the jet washing. Therefore, no pollution such as air pollution is caused by the exhaust gas from the precipitation tank. On the other hand, the fine particles in the adsorbent sediment in the water due to the difference in specific gravity from the sedimentation tank water, and accumulate as mud on the bottom in the sedimentation tank. By the way, when bulky solid waste is incinerated and treated like this method, it can be taken out as mud whose volume is greatly reduced. The volume reduction rate (%) of the solid waste in this case is approximately 0.2 to 0.6%.
It is about.

In the method for treating combustion products according to the second aspect of the present invention, when the combustion products are treated as described above, a jet (water jet) of water is generated in the junction pipe. Therefore, also in this case, the combustion products are treated in the same manner as described above. According to a second aspect of the present invention, the solidifying material is added to the fine particles or stirred in the process of transferring the fine particles settled in the sedimentation tank to the solidification vessel by the discharge pipe system. In addition, the fine particles containing the solidified material injected into the solidification container through the discharge pipe system may be solidified in the solidification container. Through these treatments, the mud-like fine particles deposited in the sedimentation tank become a block-like mass capable of maintaining its own form. Therefore,
This reduced volume facilitates subsequent handling. In addition, the reduced volume can be used for construction, construction, and other materials. This leads to solid waste becoming valuable. Of course, in the treatment method of claim 2 as well, no harmful components are released into the air, on the ground, under the ground, in public waters, and the like in various treatment steps, so there is no possibility of causing pollution.

In the method for treating a combustion product according to the third aspect of the present invention, a jet of liquid ceramic is generated in the junction pipe. Therefore, when the combustion product collides with the liquid ceramic in the merging pipe, the fine particles in the combustion product are adsorbed (trapped) by the liquid ceramic, so that a paste-like mixture of jet liquid and various fine particles is obtained. Adsorbed liquid is formed. Thereafter, when the adsorbent and the gas mixed therein flow into the sedimentation tank from the junction pipe, the fine particles captured by the adsorbent precipitate in the sedimentation tank or the gas is discharged out of the sedimentation tank. The gas exhausted here does not contain any harmful components, as described above, and even the odor components have been removed. Therefore, also in this case, no exhaust pollution is caused. According to a third aspect of the present invention, the fine particles in the precipitation tank are fed into a heating furnace and sintered. The fine particles to be sintered are already captured by the liquid ceramic. Therefore, when this is heated at a high temperature, the liquid ceramic is melted into a frit shape, and the periphery of the fine particles is covered with an enamel film. This means that the liquid ceramic capturing the fine particles is converted into a ceramic by the sintering process. When the fine particles are sealed in the ceramic in this way, the harmful components contained in the fine particles are also eluted and become non-volatile. Therefore, such a sintered product is almost harmless and safe. In addition, this sintered material becomes a valuable material for building and construction.

The method for treating combustion products according to claim 4 of the present invention is a specific embodiment of each of the above methods (claims 1 to 3). That is, according to the treatment method of claim 4, the solid waste on each floor of the building is thrown into the crusher through the dump passage and crushed, or the crushed waste in the crusher is thrown into the combustion furnace through the communication duct. This is to burn it. The details after the combustion furnace are as described above. In this case, the building may be under construction or after completion, but is generally under construction. According to the treatment method of the fourth aspect, these are continuous as in each floor of the building → crusher → combustion furnace → sedimentation tank.
Therefore, it is not necessary to transfer waste to each step. When this is combined with the above series of steps, automation can be easily achieved.

The apparatus for treating each combustion product according to claims 5 to 9 of the present invention has the following features.
Means for carrying out each of the methods of claims 1 to 4 are provided. Therefore, the apparatus for treating combustion products described in each of the above items is useful for implementing the method for treating each combustion product according to claims 1 to 4 of the present invention.

Also, a pipe end of the discharge pipe system 100 (discharge port).
Is led to the upper surface of the solidification vessel 69 installed on the combustion furnace 61. In the discharge pipe system 100, the pump 102 is a well-known Mohno pump. The solidifying material adding machine 103 injects the solidifying material into the mud introduced into the device. As a solidifying material in this case,
A material that completely solidifies a mud such as cement or a synthetic resin adhesive, or a material that is easily decomposed such as starch paste is used. Cement kneaded by adding water corresponds to a type of liquid ceramic described below. Stirrer 1
The reference numeral 04 comprises, for example, a well-known static mixer.

When treating solid waste using the apparatus illustrated in FIGS. 1 to 4, the following is an example.

When the building 10 enters the frame construction stage, the building 1
Each floor of No. 0 has various solid wastes 1 as construction waste.
Occurs. These solid wastes 1 are stored on the second floor of the building 12-
Each hopper member 22 on the fifth floor 15 of the building is dropped to the feeder 30 through the dump passage 20.

Since the dumping passage 20 is provided with an object detector (falling object detector), the fact that such waste has been input is electrically notified to, for example, the feeder 30. The feeder 30 receiving this operates for a predetermined time,
The solid waste 1 is quantitatively supplied to the crusher 40.

When the solid waste 1 is supplied in a fixed amount from the feeder 30, the crusher 40 interlocking with the feeder 30 rotates the rotary shaft 50 at a high speed so that the solid waste 1
And pulverized waste 2 into pulverized waste 2. This is because each articulated strip 52 colliding with the solid waste 1 while rotating at a high speed gives a shocking destructive force to the solid waste 1. In addition, with respect to the solid solid waste 1 which is not broken even by such a destructive force, each of the articulating strips 52 having flexibility is bent to absorb and reduce the impact with the solid waste 1. In other words, this means that each articulation strip 52 self-avoids an unexpected situation such as breakage. Since the crushed waste 2 generated in this way is scraped off by the impeller 54 in the casing 41, these paths such as the outlet 45 of the casing 41 → the communication ducts 46 and 67 → the inlet 66 of the furnace shell 62. Through the combustion chamber 6 of the combustion furnace 61
Enter 4

The combustion furnace 61 has a standby state for incineration of the waste in advance, or enters an incineration state at the same time as receiving the pulverized waste 2. Therefore, grinding waste 2
Is incinerated in the combustion furnace 61 to become ash. This means that the solid waste 1 is greatly reduced in volume by going through processes such as pulverization and incineration, and eventually becomes incinerated ash 3.

The high-pressure pump 88 of the merging transfer system 80 enters the operating state after a certain period of time has elapsed since the combustion furnace 61 started incineration of the crushed waste 2. After the operation starts, the high-pressure pump 88 sucks the water in the precipitation tank 70 from the suction pipe 89, sends the water under pressure from the discharge pipe 92 to the spray nozzle 85, and sprays it from the spray nozzle 85. Therefore, a water jet is generated in the merging pipe 87 receiving the high-speed fluidity from the injection nozzle 85 via the connecting pipe 86. The water jet generated in the confluence pipe 87 makes the two transfer pipes 82 and 84 a negative pressure to cause a suction action on these pipes. That is, due to the water jet generated in the merging pipe 87, the smoke gas in the combustion chamber 64 of the combustion furnace 61 and the incineration ash 3 in the ash fall space 65 of the combustion furnace 61 enter the merging pipe 87. That is to be sucked. The smoked gas and the incinerated ash 3 sucked in this way flow through the pipe 87 toward the precipitation tank 70 while being taken in the merge pipe 87. Confluence pipe 8 during this time
In 7, the smoke gas / incineration ash 3 collides with the jet water. Therefore, the carbon, soot,
Smoke dust particles with strong water repellency, such as fly ash, increase in hydrophilicity while being hit with jet water and are adsorbed by water, and incinerated ash 3 with strong water repellency also increases in hydrophilicity and adsorbs on water. And other harmful components are also washed out of the smoke gas. Thus, an adsorbing liquid (muddy water) such as mud in which jet water and various solid fine particles are mixed is generated in the merging pipe 87. This also includes gases in the smoke gas. The adsorbent mixed with the solid, liquid, and gas flows into the precipitation tank 70 through the junction pipe 87.

The adsorbed liquid that has reached the precipitation tank 70 is transferred to the precipitation tank 7.
The gas flows down into the cylindrical guide 72 on the inlet side of the tank 0 (the tank body 71), and the gas contained therein flows through the upper side (gas phase space) in the settling tank 70 and precipitates from the exhaust pipe 76. It is discharged out of the tank 70. The gas discharged from the precipitation tank 70 to the outside can be regarded as "no harmful component" because it is after the water jet cleaning. On the other hand, the fine particles in the adsorbing liquid settle in the water due to a difference in specific gravity from the water, and are deposited as mud-like fine particles 4 on the bottom in the settling tank 70.

The pump 102 of the discharge pipe system 100 is automatically turned on after a lapse of a predetermined time from the start of the waste treatment, or is automatically turned on when a detection signal from the sediment sensor is received. I do. That is, the pump 102
The operation state is set when the amount of the muddy fine particles 4 deposited on the bottom of the settling tank 70 reaches a predetermined level. Pump 1 after operation
02, the muddy fine particles 4 in the sedimentation tank 70 are sucked, and the muddy fine particles 4 are discharged through the pipe of the discharge pipe system 100 to the solidifying material adding machine 1.
03 → stirrer 104 → solidified container 69
When the muddy fine particles 4 reach here, the solidifying material adding machine 103 adds a predetermined solidifying material, and the stirrer 104 also stirs these when the solidifying material containing muddy fine particles 4 reach here. And the muddy fine particles 4 in which the solidified material is homogeneously mixed
Is discharged from the end of the discharge pipe system 100 into the solidification container 69. Since the solidification container 69 is in a high temperature state due to the waste heat of the combustion furnace 61, the mud-like fine particles 4 containing the solidification material are dried and solidified earlier to become the block-like solids 5 here.

The solid matter 5 thus obtained is used as a material for construction and construction when its harmful component is below the allowable value. The solid material 5 for such use can be handled as a valuable material.

In the above-described embodiment of the present invention, the solid waste 1 is put into the dump passage 20, and then the solid waste 1 is supplied quantitatively by the feeder 30 / pulverization treatment / combustion of the solid waste 1 by the pulverizer 40.

The on / off valve 83 of the transfer pipe 82 is closed by opening the on / off valve 83 of No. 4 (cutoff of the transfer pipe 82).

As for the dump passage 20 of the building 10 having a ground floor and a basement floor, the ground side has dust chute equipment as shown in the figure and the basement side has lift equipment as described above. In addition, it is possible to cope with the solid waste 1 and the like generated on the first floor 11 of the building 10 in the illustrated example with the above-mentioned lift equipment. A space extending in the vertical direction for forming the dump passage 20 may be provided on the outer wall of the building or provided inside the building as a structure integrated with the building 10.

As a variation of the above-described embodiment according to the present invention, each unit at the subsequent stage of the dump passage 20 may be installed underground. In such a case, the upper end (tip) of the exhaust pipe 76 is pulled out to the ground or connected to a washing tank.

In the above embodiment of the present invention, when each means for waste disposal is used separately from the building 10, the dump passage 20 may be omitted or the feeder 30 may be omitted.
May be omitted. When the muddy fine particles 4 deposited in the sedimentation tank 70 are processed by a separate and independent solidification processing means, the discharge pipe system 100 and the solidification container 69 are omitted.

The piping structure of the embodiment illustrated in FIGS. 5 and 6 is as follows with reference to FIG.

First, the merge transfer system 8 will be described. One transfer pipe 82 has a base end connected to the cylinder 61 a of the combustion furnace 61 and communicates with the combustion chamber 64, and a distal end connected to the peripheral surface of the connection pipe 86 and communicates with the connection pipe 86. doing. The other end of the transfer pipe 84 is connected to the bottom of the furnace shell of the combustion furnace 61 and communicates with the ash falling space 65, and the distal end of the transfer pipe 84 is connected to the peripheral surface of the connection pipe 86 to form a connection with the connection pipe 86. Communicating. The merging pipe 87 is connected at its base end to the distal end of the connecting pipe 86 and communicates therewith, or has its distal end connected to the tank body upper wall of the sedimentation tank 70 and communicates with the tank body 71 of the sedimentation tank 70. doing. The overflow pipe 75 of the settling tank 70 is connected to the upper part of the water tank 120. The suction pipe 89 of the high-pressure pump 88 is inserted into the water tank 120, and the discharge pipe 92 of the high-pressure pump 88 is connected to the injection nozzle 85 on the connecting pipe 86 side. A water supply system 140 using a water supply or the like is connected to an upper part of the water tank 120. As is apparent from FIG. 5, the liquid supply system 141 includes a pump 142 and a suction pipe 143 and a discharge pipe 14 connected thereto.
And 4. Thus, the suction pipe 143 of the liquid supply system 141 is inserted into the liquid tank 130, and the discharge pipe 144 of the liquid supply system 141 is connected to the upper part of the water tank 120.

Next, the discharge pipe system 100 will be described.
The suction port of the pump 102 in the discharge pipe system 100 is connected to the bottom opening of the settling tank 70 (tank main body 71), and the pipe end (discharge port) of the discharge pipe system 100 is connected to the hopper 168 of the rotary kiln 152. It is led to the upper surface of. The upper surface of the hopper 168 is usually covered with a lid. Therefore, the pipe end (discharge port) of the discharge pipe system 100 is connected to such a hopper lid,
Or, it will be inserted into the hopper 168.

When the solid waste is treated using the apparatus illustrated in FIGS. 5 and 6, the following is an example.

As for the water supply system 140 and the liquid supply system 141, the water supply system 140 supplies water into the water tank 120, and the liquid supply system 141 operates the pump 142 to transfer the liquid ceramics (raw liquid) in the liquid layer 130 to the water tank 120. Or to be supplied. In the water tank 120 supplied with an appropriate amount of liquid ceramics (stock solution) and an appropriate amount of water, the stirrer 121 stirs them uniformly, so that liquid ceramics having a predetermined concentration and uniformity are formed in the water tank 120. Even when the liquid ceramics in the water tank 120 is reduced to a predetermined level or less, the liquid ceramics (raw liquid) and water are detected by detecting the viscosity of the liquid in the tank.
Homogeneous liquid ceramic is supplied into the water tank 120 by being supplied into the water tank 20 or being stirred. On the other hand, the combustion furnace 61 prepares for standby for waste incineration or enters a combustion state at the same time as receiving combustibles (the crushed waste 2 and others). Thus, when the combustibles are burning, combustion products such as smoke gas and ash are generated in the combustion furnace 61.

The high-pressure pump 88 of the merging transfer system 80 enters the operating state after a certain period of time has elapsed after the start of the combustion. After the start of operation, the high-pressure pump 88 sucks the liquid ceramics in the water tank 120 with the suction pipe 89, sends it by pressure from the discharge pipe 92 to the injection nozzle 85, and injects the same from the injection nozzle 85. Therefore, the injection nozzle 85 is connected through the connecting pipe 86.
A liquid jet, that is, a jet of liquid ceramics, is generated in the merge pipe 87 receiving the high-speed fluidity from the liquid.
The liquid jet generated in the merging pipe 87 is supplied to both transfer pipes 82.
Apply a negative pressure to 84 to cause suction on these tubes. As a result, smoke gas in the combustion chamber 64 of the combustion furnace 61 and ash in the ash falling space 65 of the combustion furnace 61 are sucked into the merge pipe 87. The smoke gas and ash sucked in this way flow through the pipe 87 toward the precipitation tank 70 while being taken into the merge pipe 87. During this time, the flammable gas or ash collides with the liquid jet in the merging pipe 87. In this case, it is almost the same as above, and the affinity with the liquid ceramic is increased while the highly water-repellent dust particles such as carbon, soot and fly ash contained in the smoke gas are struck by the jet liquid. The ash with strong water repellency also increases the affinity and is adsorbed on the liquid ceramic, and other harmful components are also washed away from the smoke gas. In the merging pipe 87, a muddy and highly viscous adsorbent (muddy water) in which liquid ceramics and various fine particles (solids) are mixed is generated. This also includes gases in the smoke gas. The adsorbent mixed with the solid, liquid, and gas flows into the precipitation tank 70 through the junction pipe 87.

The adsorbed liquid reaching the precipitation tank 70 is supplied to the tank main body 7.
1, the gas contained therein flows through the upper side (gas phase space) in the precipitation tank 70 and is discharged from the exhaust pipe 76 to the outside of the precipitation tank 70. The gas discharged from the precipitation tank 70 to the outside can be regarded as "no harmful component" as in the previous example, since it is after the liquid jet cleaning. In addition, since the cleaning liquid at that time is liquid ceramics, the odor has almost disappeared. On the other hand, the fine particles in the adsorbing liquid settle in water while being adsorbed by the liquid ceramics, and are deposited as mud-like fine particles 4 on the bottom in the settling tank 70.

The pump 102 of the discharge system 100 is connected to the combustion furnace 6
It is automatically turned on after a lapse of a predetermined time from the start of combustion within 1. This means that the pump 102 is brought into the operating state at a time when the amount of the muddy fine particles 4 deposited on the bottom in the settling tank 70 reaches a predetermined level. After the start of the operation, the pump 102 sucks the mud-like fine particles 4 in the precipitation tank 70 and sends them out to the heating furnace 150 through the pipe of the discharge pipe system 100.

The heating furnace 150 is also automatically operated after a certain period of time has elapsed since the start of waste disposal,
Alternatively, the operation state is automatically set at the same time as the operation of the pump 102 or with a certain time delay from the operation of the pump 102. When the rotary kiln 152 on the gantry 151 starts operating due to the timely operation of the heating furnace 150, the conveyor 16
The third screw 166 is rotated by the motor 169,
Since this rotation is transmitted to the rotating cylinder 156 like the shaft 167 → the bearing 158 → the stay 159 → the rotating cylinder 156, the rotating cylinder 156 also rotates at the same time. In addition, the heater 170 also begins to blow hot air (flame) into the rotating cylinder 156.

The mud-like fine particles 4 sent out from the settling tank 70 to the heating furnace 150 side are fed into the hopper 168 of the rotary kiln 152 from the discharge end of the discharge pipe system 100, and then into the hopper 168 → the inlet. 164 → the inside of the cylindrical body 163 of the conveyor 163 → the outlet 165 → the inside of the rotating cylinder 156. The muddy fine particles 4 in the rotating cylinder 156 move from left to right in FIG. 6 while being sent by the internal screw 161.
The hot air blown from zero flows inside the rotating cylinder 156 from right to left in FIG. This means that the muddy fine particles 4 and the hot air have a countercurrent relationship in the rotating cylinder 156. Therefore, the muddy fine particles 4 are sufficiently heated by the hot air from the heater 170 in such a relationship. The muddy fine particles 4 that roll or move forward by the internal screw 161 are pelletized in the rotating cylinder 156 and are sintered by receiving hot air from the heater 170. The particulate matter generated in this way enters between the outer peripheral surface of the rotating cylinder (156) and the inner peripheral surface of the outer cylinder (153) through the opening 157 on the right end side of the rotating cylinder 156, and is then moved by the external screw 160. The direction is changed and both cylinders 153
• Move between 156 from right to left in FIG. Between the inner and outer peripheral surfaces of the two cylinders, the inside of the rotating cylinder 156 is heated by the heating power from the heater 170 or the outer cylinder 153 is
1 is a high temperature region because it is heated by the hot air in 1. Therefore, the granular material that also passes through the high-temperature region is almost completely sintered from the opening 157 to the outlet 154, and is turned into a frit-like ceramic. Immediately after exiting from the outlet 154, the ceramic material falls into a container (not shown) immediately below the outlet (154). If the muddy fine particles 4 do not form uniform pellets in the rotary kiln 152, the discharge pipe system 1
00 and the hopper 168, between the hopper 168 and the conveyor 163, between the conveyor 163 and the rotating cylinder 15
A known or well-known granulator may be interposed between appropriate parts such as between the unit 6 and the like.

As shown in FIGS. 5 and 6, the liquid ceramic used for treating the combustion products is the same as the aforementioned silanol salt [H
_n Si (OH) _4-n ], that is, mud-like fine particles 4
Is a mixture of a combustion product and a silanol salt, it is sintered at 900 ° C or higher to form a frit-like ceramic, so that heavy metals contained in the combustion product hardly elute Things. It is considered that the reason is that at 900 ° C. or higher, the silanol loses the hydroxyl group, leaving only the oxygen bond and ionic bond with the heavy metal. Therefore, when a silanol salt is used as the liquid ceramic, Cu.Cr.As.P
It is effective for heavy metals such as bSe. On the other hand, silanol salts for dioxins make hydrochloric acid, which is the causative substance, non-volatile and does not decompose at low temperature, and eliminate incomplete combustion. Even if dioxin is mixed with the combustion products, it is considered that this will not be eluted after the formation of ceramics. The concentration of the liquid ceramic (concentration in the water tank 120) in this treatment is 10 to 20.
% Is sufficient, and the soil waste standard value (0.01
mg / l or less). This is effective not only for waste incineration ash but also for sludge incineration ash.
The ceramic material obtained after such treatment is almost harmless, and can be used as an aggregate in the civil engineering and construction fields, for example. Therefore, this ceramic material can be handled as a valuable material.

There are many technically compatible parts between the embodiment described with reference to FIGS. 1 to 4 and the embodiment described with reference to FIGS. Therefore, applying the former technique to the latter technique and applying the latter technique to the former technique are optional matters. As an example of this case, the dust chute 20 and the feeder 3
FIG. 5 is in the vicinity of the building 10 with the crusher 40 and the like.
In some cases, the processing means shown in FIG. 6 is provided, and the end of the communication duct 67 is connected to the inlet 66 of the combustion furnace 61 shown in FIG. Also in the embodiment of FIGS. 1 to 4, the processing of the smoke gas and the processing of the ash can be performed in two stages. In such a case, the same on-off valve operation as in the previous example may be performed.
In addition, each means exemplified as an embodiment of the present invention can be applied not only to waste incineration but also to any case in which a substance burns to generate a combustion product.

[0070]

The method for treating combustion products and the apparatus for treating combustion products according to the present invention have the following effects.

[Pulverizing Effect, Incineration Effect, Volume Reduction Effect] Solid wastes are various in shape and properties and are difficult to handle mechanically. It becomes possible, and the subsequent incineration treatment also increases the combustion efficiency because only the inflammable waste is incinerated by pulverization. In addition, crushing or incineration of the solid waste greatly improves the volume reduction rate.

[Adsorption Treatment Effect] In the process of transferring the combustion products to the precipitation tank, the flammable gas or ash and the jet liquid collide in the merging pipe. In this case, fine particles with strong water repellency, such as carbon, soot, and fly ash, contained in the smoke gas increase their affinity with the jet liquid while being struck. Adsorbed to liquid. Ash with high water repellency also has an increased affinity and is adsorbed by the liquid. Other harmful components are also washed out of the smoke gas. Therefore, the effect of treating fine particles and harmful components is high, and the subsequent precipitation treatment is promoted. In the case of using a liquid jet, the above-described adsorption treatment can be performed simultaneously with the transfer of the ash or smoke gas. That is, since the transfer and the adsorption treatment can be performed by a single means, the intermediate treatment is rational.

[Effects of Precipitation Treatment] Solid fine particles are liable to be scattered and dusted, and gas with a bad smell is also easily dissipated. However, these are precipitated in water or washed off and trapped, so that final treatment is easy. .

[Suppression and Prevention of Pollution] Since various treatments are performed in a closed system, harmful components contained in solid waste are hardly released to the outside. The gas discharged from the precipitation tank to the outside also contains no harmful components since this is after the liquid jet cleaning. Therefore, it does not cause pollution such as air pollution, public water body pollution, and ground pollution. Especially when using liquid ceramics,
It has a high containment effect for solid harmful substances and a high trapping effect for gaseous harmful substances.

[Space-Saving, Resource-Saving, and Low-Cost Treatment] The means for performing each treatment can be concentrated and installed near the site where solid waste is generated. There is no need to transport the goods to the treatment plant. The place where the power source is consumed is limited to the area related to crushing and transfer, and in the case of burning incineration of waste, the fuel is often sufficient only at the beginning of combustion. Therefore, running costs are also reduced.

[Automation] Necessary processing means are connected in series and there is almost no dependence on human labor, so that the entire processing system can be automated.

[Effect of Treating Valuables] When solidifying mud-like fine particles, it is possible not only to facilitate the subsequent handling of reduced volume substances but also to treat them as valuables.
In particular, the incineration (combustion) of the waste is inexhaustible and the combustion products are inexhaustible, and it is valuable. Be able to cover.

[Effect of connection with building] When solid waste is put into the crusher from each floor of the building through the dump passage, the trouble of transporting the solid waste to the crusher is not required, and the processing system is not required. Automation is more perfect. Such a mode is particularly effective for a building in the middle of construction that discharges a large amount of construction waste.

[Other effects] Since the treatment means can be provided near the site where solid waste is generated, there is no need to transport the solid waste to a distant treatment site. That is, there is no room in this processing system to cause traffic problems caused by garbage trucks and the like. In addition, garbage disposal sites (disposal sites), for which the shortage of absolute numbers has been pointed out, can also contribute to resolving this.
