Description

Organic matter processing equipment with steam generation function

The present invention relates to an organic substance processing apparatus that thermally decomposes an organic substance such as a synthetic resin material so that it can be disposed of as ash and gas, and newly has an organic substance processing apparatus having a steam generating function.

By heating the organic matter put into the treatment tank that shuts off the outside air and supplying magnetized air (magnetized air) to the treatment tank in a suppressive manner, the organic matter is kept at a relatively low temperature without generating harmful substances such as dioxins. A processing technique for thermal decomposition is known.
Since magnetized air activates oxygen by magnetic force to generate a large amount of negative ions, it has the property of causing a violent pyrolysis reaction with carbon molecules of organic matter. As a result, the organic matter is oxidatively decomposed into water, ash (inorganic matter, carbon, etc.) and gas (carbon dioxide, hydrocarbon, etc.).

As a device for processing an organic substance by suppressing the magnetized air in this way, for example, Patent Document 1 states that the magnetized air is supplied to the lower part of a processing tank in which the outside air is blocked and the charged organic substance is heated. A supply mechanism is attached, and when the temperature sensor detects that the inside of the processing tank has exceeded a certain temperature, the amount of magnetized air supplied by the magnetized air supply mechanism is adjusted for the magnetized air in the magnetized air supply mechanism. It is described that the electromagnetic valve is operated by the controller so as to reduce the supply amount.
Then, when the temperature inside the treatment tank becomes an environment suitable for thermally decomposing organic matter, the supply of magnetized air is automatically reduced by the cooperation of the solenoid valve, temperature sensor, and controller, and the organic matter burns at a high temperature. It can be prevented from becoming a state.
However, even with this device, the temperature inside the processing tank is not always uniform, and even if multiple temperature sensors are installed, it is difficult to accurately grasp the temperature inside the processing tank. There is a problem that the timing of operating the valve becomes inaccurate, and it is not possible to surely realize an environment suitable for thermally decomposing organic substances.

On the other hand, the present inventor has invented the processing apparatus described in Patent Document 2 in advance, and has been able to reliably realize an environment suitable for thermally decomposing organic substances by supplying magnetized air.
However, even with this device, although organic matter is effectively pyrolyzed by magnetized air, it does not become harmless to the organic matter generated by thermal decomposition, and gases such as hydrocarbons are released into the atmosphere without being treated. There was a risk of
In addition, since the water vapor generated in the process of treatment is released as it is, there remains a problem that useful water vapor is not utilized.

Further, in this processing tank A, a heat exchanger C having a drum-shaped main body 141 is attached to the upper portion thereof, and the gas containing thermally decomposed hydrocarbons and the like is cooled in the main body 141. It becomes liquid, and when the liquid gradually accumulates on the bottom of the dome shape, the processing becomes troublesome.

It is characterized in that a gas guide wall having a wide gap is erected near the center of the cylinder.

The invention of claim 4 is characterized in that, in the above invention, the water level sensors of the water level holding portion are arranged at at least two or more positions above and below.

In the invention of claim 5, in the above invention, an introduction pipe is vertically provided so as to face the bottom of the main body of the heat exchanger C, and an introduction path in which a trap pipe is arranged is provided at the end of the introduction pipe. Under the pipe, a heating plate for vaporizing the dropped liquefied gas, an air supply port for sending the vaporized gas to a duct connected to the combustion processing mechanism B, and a vaporization chamber having an air supply pipe are formed, and the periphery of the vaporization chamber is formed.

Then, the dried hydrocarbons and the like supplied from the heat exchanger into the high-temperature processing furnace rise in the heating element group that radiates far infrared rays heated from the lower part of the high-temperature processing furnace by the heating unit. At that time, the temperature rises due to the heat generated by the heating element, and the hydrocarbons and the like reach the high temperature treatment space and are treated into harmless gas at a high temperature of 800 ° C. or higher. For example, the hydrocarbons and the like are treated at high temperatures to become harmless substances of carbon dioxide and water (water vapor).
The temperature inside the high-temperature processing furnace is heated by the burner to a high temperature state set while detecting the temperature inside the furnace with a temperature sensor, and is controlled by the high-temperature holding unit to a high temperature of 800 ° C. or higher.

Then, the harmless gas cooled to a low temperature is released into the atmosphere by the gas delivery unit.

Then, in the apparatus of the present invention, a storage space capable of storing a certain volume of steam is formed above the cooling tanks connected to the high-temperature processing furnace. Then, in the process in which the high-temperature gas sent from the high-temperature processing furnace from 800 ° C. to 1200 ° C. passes through the communication cylinder, the heat exchanged there produces steam, which rises as bubbles, and the above It is stored in the storage space. At this time, since a plurality of fins are arranged in the communication cylinder, heat exchange is efficiently performed between the water in the cooling tank and the hot air passing through the communication cylinder through the fins, and a large amount of water vapor is generated.
At this time, since the water level sensor provided in the water level holding unit catches the water level and keeps the water level within a certain range, the water vapor storage space can hold a certain volume and surely stores a certain amount of water vapor. Can be done.

The whole is directly heated by hot air from the bottom to the top to generate heat, and the heating element group in the upper stage receives heat from the heating element in the lower stage heated by the heating unit and generates heat to a temperature of 800 ° C. or higher. Then, the high temperature treatment space above it can be stably maintained at a high temperature of 800 ° C. or higher.
Then, it becomes possible to surely change hydrocarbons and the like into harmless gas in the stable high temperature.

The invention of claim 3 is provided in a large-diameter cylindrical portion when a communication cylinder arranged in the cooling treatment tank meanders in water from side to side and moves high-temperature gas from the top to the bottom of the water tank. The gas guide wall guides the gas in the cylinder so as to pass through the gap with the peripheral wall surface, so that the high temperature gas is positively brought close to the water having a low temperature, so that the heat exchange efficiency can be improved.
As a result, it becomes possible to efficiently cool the high-temperature gas.

In the invention of claim 4, by arranging the water level sensors of the water level holding unit at at least two or more positions above and below, the upper and lower water levels are captured and the water level is kept within the range. It can be maintained at the volume specified by the lower limit.

As shown in FIGS. 5 and 6, the liquefied gas treatment mechanism D first forms a main body introduction path 143 in the lower part of the main body 141. Specifically, the introduction pipe faces the main body 141. 143a is arranged, and a trap pipe 143b for storing the liquefied gas L in which hydrocarbons and the like are liquefied is connected to the arrangement thereof, and the tip portion thereof faces the vaporization chamber 145. The vaporization chamber 145 heats the liquefied gas L to vaporize it.

As shown in FIG. 1, the combustion treatment mechanism B connected to the heat exchanger C detoxifies and odorless gas G containing hydrocarbons and the like produced by thermal decomposition of the organic substance P in the treatment tank A at a high temperature. It is provided with a high-temperature processing furnace X for converting the heat, and a cooling treatment tank Y for cooling the gas G having a high temperature in the high-temperature processing furnace X with water W.
The high temperature processing furnace X is installed in the vicinity of the processing tank A, and the cooling treatment tank Y is installed in the vicinity of the high temperature processing furnace X.
Then, a duct 11 for moving the gas G is provided between the heat exchanger C at the upper part of the processing tank A and the high temperature processing furnace X by connecting to the lower part of the high temperature processing furnace X. A duct 12 for moving the gas G is provided between the cooling treatment tank Y and the upper part of the high temperature treatment furnace X and the upper part of the cooling treatment tank Y.

The high temperature processing furnace X is formed in a size having a volume capable of accommodating a heat generating portion 4 having a large number of exothermic materials 41 inside, and as shown in FIG. 2, the circumference of the furnace is 1300 ° C. or higher. The inside of the furnace is enclosed in a sealed state by using the heat-resistant material 31 that can withstand the high temperature of the above.
FIG. 2 shows an embodiment in which three layers of heat-resistant material 31 formed in a thick plate shape are laminated and bonded to improve the heat-resistant performance in response to a high temperature of 1300 ° C. or higher.

From the lower part to the middle part inside the high temperature treatment furnace X, the heat generating part 4 forms a gap through which gas can pass through the ceramic heating element 41 having a heat storage property and having a far infrared radiation function. The structure is such that many are installed.
The heating element 41 is made of a ceramic material that emits far infrared rays, has excellent heat storage properties, stores the heat when heated to a high temperature, and uses a material that generates heat by itself.
For example, a ceramic having silicon carbide as a main component and containing aluminum oxide, silicon dioxide and the like is formed in a tube and sintered.
The heating element 41 shows a form in which a tubular heating element 41 is used in FIG. 2, but in addition to this, a heating element in which ceramic is formed in a rod shape, a plate shape, a block shape, or the like can also be used.

The tubular heating element 41 is distributed in the high-temperature processing furnace X and fixed to the furnace wall of the heat-resistant material 31. For example, the tubular heating element 41 is mounted vertically in the lower stage region by inserting it into the bottom wall with a gap between them. However, in the middle region, a gap is provided between them and the wall is inserted horizontally into the side wall, and in the upper region, a gap is provided between the two and the side wall is inserted horizontally.
In the above-exemplified arrangement, a mode in which the heating element group in the lower region and the heating element group in the middle region are distributed with a space between them is shown.
Since the optimum size, number, mounting interval, arrangement, etc. of the heating element 41 are determined by the processing capacity and size of the furnace, the distribution of each stage is not limited to the above mode.

The upper part of the heating element 41 provided in the upper region of the furnace is hollow to provide a high temperature treatment space 30. A high temperature processing unit 3 is provided.
Further, in the lower part of the high temperature treatment furnace X, a gas receiving port 21 for supplying the gas G moved from the heat exchanger C into the furnace through the duct 11 is provided.
As shown in FIG. 2, the gas receiving port 21 may be opened at the lower part of the side surface, or may be opened at the bottom surface (not shown).

Further, a heating unit 4 is provided in the lower part outside the high temperature treatment furnace X.
The heating unit 4 has a burner 51 into which the nozzle 52 is inserted from the lower part to the upper part in the tank, and the burner 51 heats the heating element 41 group in the lower stage region, and the fuel is gas or oil. Can be used.
As shown in FIG. 2, the nozzle 52 of the burner 51 is provided on the bottom surface so that the gas G enters from below the heating element 41 group in the lower stage region, or the heating element 41 group in the lower stage region is not shown. It can also be provided at the bottom of the side so that gas can enter from the side of the.

Further, the high temperature treatment furnace X is provided with a high temperature holding portion 6 for controlling the temperature of the high temperature processing empty portion 3 and holding the temperature at a high temperature.
To control the temperature inside the furnace, a temperature sensor 61 is provided in the furnace toward the high temperature treatment space 30 in order to maintain the temperature of the high temperature treatment space 30 at a high temperature of, for example, at least 800 ° C. When the temperature sensor 61 detects that the temperature inside the temperature exceeds 900 ° C., the temperature controller 60 connected to the temperature sensor 61 stops the operation of the burner 51.
When the temperature sensor 61 detects that the temperature inside the furnace has dropped to 800 ° C. or lower, the temperature controller 60 operates the burner 51 to raise the temperature.
That is, the burner 51 is not always operated, but is operated when the temperature is low at the start of operation or when the temperature inside the furnace temporarily drops below 800 ° C. to raise the temperature to 800 ° C. or higher. It is for raising.

In the high temperature state in the high temperature processing space 30, the gas G itself burns to generate thermal energy.
Therefore, once the normal operating state is entered, the heat generated by the heat energy stored in the heating element 41 and the gas are generated in the high temperature processing space 30 at the high temperature of the surrounding heat resistant material 31 which is heated to a high temperature. A high temperature state of 800 ° C. to 1300 ° C. is maintained due to the addition of heat generated by combining G with oxygen.
Therefore, the operation of the burner 51 can be temporarily stopped while the temperature is maintained at a high temperature of 800 ° C. or higher. Therefore, fuel can be saved.
The high-temperature gas has a property of rising, and when the gas G entering from the gas receiving port 21 of the high-temperature processing furnace X rises between the heating elements 41 and passes through the gaps of the heating elements 41, the heating element 41 The temperature rises while increasing according to the temperature gradient, and reaches the high temperature processing space 30 to reach 800 ° C. to 1300 ° C.

Then, once the normal operating state is entered, the organic matter P is thermally decomposed by the magnetized air M in the processing tank A, and the gas G generated is dried in the heat exchanger C at a temperature of about 200 ° C. and treated at a high temperature. Enter the high temperature treatment furnace X from the gas receiving port 21 at the bottom of the furnace X.
In the high-temperature treatment furnace X, the gas G rises in the furnace while raising the temperature through the heating elements 41 that are heated and is in a heating state, and becomes a high-temperature treatment space 30 having a high temperature of 800 ° C. or higher. To reach.
In the high temperature treatment space 30, the gas G reacts with oxygen in a high temperature environment of 800 ° C. or higher, and changes into harmless carbon dioxide gas and water.
In the reaction, a part of oxygen in the magnetized air M supplied from the magnetized air supply mechanism 105 to the inside of the processing tank A is consumed in the processing tank A, but the remaining oxygen is consumed in the processing tank A. It is contained in the generated gas G, enters the high temperature treatment furnace X, and is consumed in a high temperature environment.

Then, the gas G containing water vapor and carbon dioxide generated by detoxifying the gas G generated by the thermal decomposition of the organic matter in the high temperature treatment furnace X moves to the upper part of the next cooling treatment tank Y via the duct 12. Let me.

As shown in FIG. 1, in the cooling treatment tank Y, the outer periphery of the tank filled with water W and sealed all around is covered with a heat insulating material 79 such as glass wool, and gas is contained in a communication cylinder 71 meandering in water. Is provided from the top to the bottom to cool the gas by heat exchange between the gas and water.
The cooling unit 7 connects the upper end and the lower end of the communication cylinder 71 between the gas receiving unit 23 provided at the upper part of the tank and the gas delivery unit 24 provided at the bottom of the tank so as to communicate with the high temperature treatment furnace X. To do.
Then, a plurality of fins 78 for promoting more efficient heat exchange are arranged on the outer circumference of the communication cylinder 71 along the orbit around the communication cylinder 71.
Further, a blower 10 for forcibly moving the gas in the communication cylinder 71 from the upper part to the lower part of the tank is connected to the gas delivery unit 24.
The blower 10 is attached to the tip of the duct 13, and the gas G discharged from the communication cylinder 71 is discharged into the atmosphere from the discharge port 25 at the end of the duct 13.
The gas receiving unit 23 is communicably connected to the high temperature processing empty portion 3 of the high temperature processing furnace X via a duct 12.
Further, the gas delivery unit 24 is connected to the blower 10 for forcibly moving the gas in the communication cylinder 71 from the upper part to the lower part via the duct 13. Then, the gas G sucked from the communication cylinder 71 by the operation of the blower 10 is released into the atmosphere from the discharge port 25.
As described above, in the cooling treatment tank Y, the high temperature treatment furnace X raises the gas G into the furnace, whereas the high temperature gas G in the communication cylinder 71 resists the natural rising force. It is forcibly pulled down with a blower.

Then, a storage space 81 having a constant volume for storing water vapor is formed above the cooling unit 71 above the communication cylinder 71 of the cooling unit 7 of the cooling treatment tank Y, and water vapor is discharged from the storage space 81 to the outside of the system. A steam generating section 8 is provided in which a lead-out pipe 83 is provided with a discharge valve 82 for sending out the steam.
The steam generating unit 8 is intended to utilize the steam generated in the communication cylinder 71, secures a space having a constant volume according to the purpose, and tries to temporarily store the steam in the space.
Then, the lead-out pipe 83 guides it to a device outside the system, for example, a boiler for power generation, a heating device for a hospital, a building, or the like, and effectively utilizes the steam generated in the organic matter processing device. ..

Then, a water level holding portion 9 for holding the storage space 81 is provided, and in conjunction with this, a water supply portion 92 for supplying water into the tank and a drainage portion 93 for discharging excess water to the outside of the tank are provided at the bottom of the tank. Arrange in.
In the water level holding portion 9, an upper limit sensor 91a and a lower limit sensor 91b arranged at least in the vertical position are arranged in the upper part of the tank, and a standard sensor 91c is arranged in the middle as necessary. The upper limit sensor 91a and the lower limit sensor 91b set the upper limit and the lower limit of the water level in the tank, the upper limit sensor 91a secures the minimum volume of the storage space 81, and the lower limit sensor 91b secures the maximum volume of the storage space 81. The standard sensor 91b is set to an average volume.

The water supply unit 92 is provided with solenoid valves 92b and 93b of the water supply pipe 92a of the water supply unit 92 and the drainage pipe 93a of the drainage unit 93, and a water level controller that controls opening and closing based on the water level detected by the water level sensor 91. 90 is arranged.
Then, a high-pressure pump 92c for forcibly supplying water is added to the water supply pipe 92a so as to surely maintain the volume of the storage space 81 even when the pressure in the storage space 81 increases.

By the way, in the present invention, the direction of arrangement of the communication cylinder 71 is not an upward direction but a downward direction, and a cooling means is taken according to a temperature gradient in which the temperature becomes lower toward the lower side.
That is, when the direction of arrangement of the communication cylinder 71 is downward, the water temperature in the cooling tank becomes a temperature gradient that becomes lower as it goes lower, and when the high temperature gas G enters there from the gas receiving unit 23. Initially, the high temperature gas G maintains a high temperature close to the temperature from the gas receiving portion 23, and heat is exchanged through the communication cylinder 71 and its fins 78 to generate a large amount of water vapor. Then, when going further downward, there is less vertical convection in the cooling tank as in the case of upward, and the temperature gradient that becomes lower as it goes downward is surely maintained. Therefore, the temperature of the high temperature gas G and the cooling tank A constant temperature difference is maintained between the temperature and the water temperature inside, and an effective heat exchange action works. When this effective heat exchange action extends over the entire length, the generation of water vapor generated from the heat exchange action also extends over the entire length.
Therefore, the most effective effect of water vapor generation can be obtained under this temperature gradient.

The movement of the gas G to be processed in the high temperature processing furnace X and the cooling processing tank Y is connected to the lower end of the communication cylinder 71 of the cooling processing tank Y because all the passages of the

ducts

11, 12, and 13 are communicated with each other. It is performed by operating the blower 10 provided in the duct 13, and the moving speed can be adjusted according to the amount of organic matter to be charged and the processing status of the gas G.

Then, the high-temperature gas G in the high-temperature processing space 30 of the high-temperature processing furnace X is sucked into the communication cylinder 71 by the operation of the blower 10, and water is bent left and right in the water W from the upper end of the communication cylinder 71. The water gradually cools in W according to the temperature gradient of the water and proceeds downward, and is forcibly discharged to the outside from the exhaust port 25 by the blower 10 through the duct 13 from the lower end of the communication cylinder 71.

Further, the communication cylinder 71 of the cooling unit 7 that communicates vertically in the water W in the cooling treatment tank Y needs to have a function of allowing gas G to pass through and efficiently exchanging heat with water. Various forms are possible.
For example, in the form shown in FIG. 3, the communication cylinder 71 has an upright large-diameter cylindrical portion 72 having a large diameter and a small-diameter cylindrical portion 75 having a height substantially equal to that of the large-diameter cylindrical portion 72 but a small diameter. Multiple connections are made alternately in different directions.
In this embodiment, the large-diameter cylindrical portion 72 includes an upper surface plate 72a covering the upper surface of the cylinder and a lower surface plate 72b covering the lower surface of the cylinder, and the upper surface plate 72a is provided with an eccentric upper communication port 73 and the lower surface plate 72b. Is provided with an eccentric lower communication port 74 on the opposite side of the upper communication port 73.
Then, the upper small-diameter cylindrical portion 75 is connected to the upper communication port 73, and the lower small-diameter cylindrical portion 75 is connected to the lower communication port 74, and this structure is repeatedly repeated up and down to form one single piece. The communicating cylinder 71 is formed.
At this time, a plurality of fins 78 for promoting the generation of steam may be arranged on the outer periphery of the communication cylinder 71, and the mode may be provided in the small-diameter cylindrical portion 75 or in other portions. It is possible, and by providing more, the contact area with water is increased, the heat exchange efficiency is increased, and more steam can be generated.

Further, a gas guide wall 76 is provided in the large-diameter cylindrical portion 72 so that the gas can be brought closer to the peripheral wall surface side and circulated.
The gas guide wall 76 is curved so as to surround the lower communication port 74 that has been offset to connect the lower small-diameter cylindrical portion 75, and both ends of the wall surface and the circumference of the large-diameter cylindrical portion 72. A gap 77 through which gas can flow is formed at a distance from the wall surface 72c. Then, the upper part of the wall surface is fixed to the upper surface plate 72a, and the lower part of the wall surface is fixed to the lower surface plate 72b.
In this embodiment, a gap 77 is provided between both ends of the gas guide wall 76 and the peripheral wall surface 72c of the cylinder to form a flow path through which the gas G flows, so that the gas is close to the cold water on the peripheral wall surface side. It is possible to efficiently cool the high temperature gas by passing through.

By the way, the steam sent out of the system through the discharge valve 82 and the outlet pipe 83 arranged in the storage space 81 of the steam generating section 8 is used for the operation of the steam turbine of the generator and the heater / water heater of the hospital or building. It can be used for heating and the like.

The high-temperature gas G generated by the thermal decomposition of the organic substance P and rising inside the treatment tank A enters the heat exchanger C, is cooled inside the heat exchanger C, and contains hydrocarbons together with the water contained in the gas G. The organic matter is liquefied to become a liquefied gas L, and the liquefied gas L is stored in the bottom of the main body 141 of the drain type heat exchanger C and is guided from the introduction pipe 143a facing the drain.
The liquefied gas L in which the hydrocarbon or the like is liquefied is temporarily stored in the trap pipe 143b, and eventually enters the vaporization chamber 145 as droplets from the tip end portion, and falls into the heating plate 145a at the bottom of the vaporization chamber 145 directly below.
A heating space 146 is formed around the outside of the vaporization chamber 145, and a warm air intake port 146a arranged on one side of the heating space 146 is connected to the cooling portion 7 of the cooling treatment tank Y via the connecting pipe 147a of the connecting path 147. Since it is connected to the disposed discharge port 25, the gas G exiting the discharge port 25 is introduced into the heating space 146.
Then, the temperature of the gas G reaching the discharge port 25 has decreased via the cooling treatment tank Y, but it is still in a state of retaining residual heat of about 140 to 160 ° C. Therefore, when the warm air retaining the residual heat is introduced into the heating space 146, it warms the heating dish 145a of the vaporization chamber 145 surrounding the outside and its surroundings, raises the temperature of the dropped liquefied gas L, and eventually vaporizes it. Acts like.
The gas circulating in the heating space 146 is discharged to the outside of the system in a detoxified form as it is from the exhaust port 146b connected to the duct 10 arranged on the other side of the heating space 146.

On the other hand, the gas body vaporized in the vaporization chamber 145 rises in the chamber to reach the air supply port 145b, and the heat exchanger C at the upper part of the treatment tank A and the high temperature treatment furnace X pass through the air supply pipe 145c. It is incorporated into the duct 11 in between.
Then, since the duct 11 guides the gas G to the gas receiving portion 21 at the lower part of the high temperature treatment furnace X, the gas incorporated therein is directly detoxified by the high temperature treatment furnace X and the cooling treatment tank Y. Will be received. That is, the liquefied gas L is treated as harmless by the detoxification action of the high temperature treatment furnace X and the cooling action of the cooling treatment tank Y, as in the organic matter treatment apparatus.

Further, in the duct introduction path 144 provided as another aspect of the introduction path, the introduction tube 144a is arranged so as to be connected to a part of the duct 11 so that the end thereof is located directly above the heating plate 145a. Since it is arranged, it is vaporized by heating in the same manner as the main body introduction path 143, and after vaporization, it is incorporated into the duct 11.

The present invention has the above configuration, and the organic substance P charged into the treatment tank A can be thermally decomposed, and the generated ash can be discharged and disposed of in a landfill or the like.
On the other hand, the gas G generated by the combustion of the organic substance P is detoxified in the high temperature treatment furnace X, further cooled in the cooling treatment tank Y, and released into the atmosphere.
Depending on the scale, it is possible to provide a plurality of high-temperature processing furnaces X and cooling processing tanks Y, and since the exhausted gas G is higher than room temperature, the heat can be effectively used in a dryer or the like. it can. The high temperature treatment furnace X and the cooling treatment tank Y are not installed on the treatment tank A according to the rising property of the high temperature gas, but the high temperature gas G is forcibly moved by a blower. It can be installed side by side on the installation surface at the same height as the processing tank A, and the whole can be made compact without being expensive and bulky.

Then, in addition to the treatment of the above organic matter, the apparatus of the present invention also serves as a steam generator, and the steam generated in the above process is used, for example, for the operation of the steam turbine of a generator, for hot water supply and heating of a building, and the like. It also has functions that can be used.

Further, if the liquefied gas treatment mechanism D is added, the liquefied gas L generated in the process of operating the organic matter treatment apparatus of the present invention, which is difficult to treat, can be treated, and the mechanism includes the treatment layer A, the high temperature treatment furnace X, and cooling. It is rational that the cooperation of the treatment tank Y can be utilized and the warm air including the residual heat of about 140 to 160 ° C. via the cooling treatment tank Y can be utilized as the heat source.

The present invention is widely used as equipment for treating waste in waste treatment facilities, factories where various organic substances are discharged, steam turbines of generators, boilers of various devices, heating / cooling devices, hot water supply devices, and the like. It is possible to use it.
