Description

The present invention relates to an organic matter thermal decomposition treatment system.

In recent years, processing technology for thermally decomposing organic matter at relatively low temperatures has been developed, and it has become possible to dispose of organic waste without generating harmful substances such as dioxins.

As this treatment technique, for example, a method is known in which organic matter is put into a treatment tank that is shut off from outside air, the organic matter is heated, and magnetized air (magnetized air) is supplied in a suppressed manner to the treatment tank.

Here, since magnetized air activates oxygen by magnetic force and generates a large amount of negative ions, it has the property of causing a violent thermal decomposition reaction with carbon molecules of organic matter.
As a result, the organic matter is oxidized and decomposed into water, ash (inorganic matter, carbon, etc.), and gas (carbon dioxide, hydrocarbon, etc.).

The technology that uses the above technology includes a treatment tank that heats the input organic matter while the outside air is shut off, a magnetized air supply mechanism that is attached to the bottom of the treatment tank and supplies magnetized air into the treatment tank, and a magnetized air supply mechanism. A solenoid valve that adjusts the supply amount of magnetized air, a temperature sensor that detects the temperature inside the processing tank, and a temperature sensor that is connected to the solenoid valve and temperature sensor and indicates that the temperature inside the processing tank has exceeded a certain temperature. In an organic matter processing device, the controller is configured to operate a solenoid valve to reduce the supply amount of magnetized air in the magnetized air supply mechanism when detection is detected. A gas flow mechanism is provided that causes the gas to flow from above to below. An organic matter processing device including a blower that causes the organic matter to be processed is disclosed (see, for example, Patent Document 1).

JP2013-215655A

However, in the organic substance processing apparatus using magnetized air described in Patent Document 1, when the temperature sensor detects that the temperature inside the processing tank exceeds a certain temperature by connecting to a temperature sensor, the magnetized air in the magnetized air supply mechanism This requires complex control such as operating a solenoid valve to reduce the amount of gas supplied.

Furthermore, although the organic matter treatment device using magnetized air described in Patent Document 1 is a suitable technology for use in large-scale furnaces, it is not suitable for inexpensive, small-scale, and medium-sized furnaces, which are in increasing demand these days.

Note that the detailed configuration of the treated water purification device 300 will be described later.

<Configuration of pyrolysis treatment apparatus 100>
As shown in FIG. 2, the pyrolysis treatment apparatus 100 according to the present embodiment includes a pyrolysis furnace 110, a burner 120, a combustion treatment mechanism 130, a suction nozzle 140, an electromagnetic valve 150, a temperature sensor 160, and a controller. 170 and a gas flow mechanism 180.

The thermal decomposition furnace 110 thermally decomposes the organic matter P in a state where outside air is shut off.
The pyrolysis furnace 110 is formed of a wall material consisting of an upper surface, a lower surface, and a side surface with a heat insulating material interposed therein to prevent the temperature of the outside surroundings from rising, and is installed so that the axis center is vertical. .

An input port 111 into which organic matter P is input is provided on the upper surface of the pyrolysis furnace 110.
The input port 111 of this pyrolysis furnace 110 has a double door structure in which an upper door and a lower door are selectively opened and closed.
For example, the input port 111 has a double structure in which the upper door has a hatch structure and the lower door has a slide hatch structure.
Specifically, as shown in FIG. 4, when the upper door of the input port 111 is opened, a temporary storage area for organic matter P with the lower door as the bottom surface is exposed.
At this time, the lower door is supported by a closing damper.
When organic matter P is put into the temporary storage area of the input port 111 and the upper door is closed, the lower door is opened by moving the closing damper that supported the lower door upward, as shown in Fig. 5. The organic matter P is then charged into the pyrolysis furnace 110.
Note that an article whose raw material is an organic substance P whose moisture content is within a predetermined range is inputted into the input port 111 through pretreatment.
In addition, the processing method in the pyrolysis treatment apparatus 100 is such that when the amount of residual organic matter in the pyrolysis furnace 110 reaches a first predetermined volume with respect to the volume of the pyrolysis furnace 110, a new amount of a second predetermined volume is generated. The method is such that the organic matter P is charged through the input port 111 of the pyrolysis furnace 110.
Here, as the first predetermined volume, for example, the capacity of the organic matter P in the pyrolysis furnace 110 is about 1/5, and as the second predetermined volume, for example, 2/3 of the volume in the pyrolysis furnace 110. can be exemplified.

A discharge port 112 is provided at the lower part of the side surface of the pyrolysis furnace 110 for discharging the ash produced by thermally decomposing the organic matter P.
In the lower part of the interior of the pyrolysis furnace 110, a rostol 113 is disposed horizontally, in which the organic matter P being pyrolyzed is deposited.

FIG. 3 is a cross-sectional view of the pyrolysis furnace 110.
As shown in FIG. 3, the pyrolysis furnace 110 has a rectangular shape including an outer steel plate 114, an inner steel plate 115, and a bottom steel plate 116, and at least the inner steel plate 115 and the bottom steel plate 116 are made of ductile cast iron. .
Further, the outer steel plate 114 and the inner steel plate 115 are formed with a gap, and this gap allows gas G generated in the pyrolysis furnace 110, for example, at a temperature of 530°C to 550°C, to be transferred to the pyrolysis furnace 110. A flow path is formed to supply the reaction area formed at the bottom of the chamber.
Furthermore, diffuser pipes 117A and 117B introduce air into the negatively ionized water (water substance, water molecules, spheres) supplied to the reaction area from a suction nozzle 140, which will be described later, and which has a discharge port protruding into the reaction area. is provided.

The air diffuser 117A is attached to the front and rear surfaces of the pyrolysis furnace 110 at a predetermined angle θ1.
The shape of the diffuser tube 117A is as shown in FIGS. 9 and 10, and the number or arrangement of the diffuser tubes 117A can be changed depending on the volume inside the furnace.
The tip of the air diffuser 117A is shaped in consideration of the influence of ash.

The diffuser pipe 117B is attached to the side surface of the pyrolysis furnace 110 at a predetermined angle θ2.
The shape of the diffuser tube 117B is as shown in FIGS. 10 and 11, and the number or arrangement of the diffuser tubes 117B can be changed depending on the volume inside the furnace.
The tip of the air diffuser 117B is shaped in consideration of the influence of ash.

The burner 120 heats the organic matter P whose moisture content is controlled, and uses gas or kerosene as fuel to ignite the organic matter P whose moisture content is controlled, and uses the combustion temperature of the organic matter P to heat the inside of the furnace. It raises the temperature.
Note that when the furnace temperature reaches the furnace temperature for normal operation using the combustion temperature of the organic matter P, the pyrolysis furnace 110 shifts to normal operation.
In this embodiment, the temperature inside the furnace during normal operation may be, for example, 530°C to 550°C.

The combustion treatment mechanism 130 renders gas G generated by thermal decomposition of organic matter P harmless and odorless through combustion treatment.
On the upper surface of the pyrolysis furnace 110, for example, a catalyst material is raised in the shape of a chimney, connected to communicate with the inside of the pyrolysis furnace 110, and surrounded by a refractory material inside a square combustion chamber. It is accommodated.
The combustion chamber is formed to have a certain volume so that it can accommodate a large amount of catalyst material.

The refractory material is made of, for example, a ceramic material that can withstand high temperatures of 1000°C or more and has heat insulation properties, and covers the entire inside surface except for a part of the upper and lower surfaces where the gas G in the combustion chamber rises. There is.
The catalyst material is, for example, sintered into a porous block body mainly composed of silicon carbide (SiC).
For this catalyst material, for example, aluminum oxide (Al203, 28% by weight or less) and silicon dioxide (SiO2, 10% by weight or more) are added to silicon carbide (60% by weight or more), which serves as a heating element, as a catalyst to assist in heat generation. It is preferable to form them into a plate shape and stack them so that the thickness direction coincides with the vertical direction of the combustion chamber.

Further, at the lower part of the combustion chamber, an outside air inlet is provided to introduce oxygen (outside air) as an auxiliary agent for combustion processing.
Further, a blower is provided near the combustion chamber to forcibly draw and introduce outside air into the outside air inlet.

As shown in FIG. 6, the suction nozzle 140 has a container loaded with porous sintered ceramic balls shown in FIG. 8 installed inside a pipe.
The suction nozzle 140 introduces oxygen (outside air), and when the introduced oxygen (outside air) passes through a porous sintered ceramic ball, it causes an electrical reduction effect and negatively ionized water (water substance/water molecules/spheres) are charged into the furnace and reduced.
Thereby, the introduced oxygen (outside air) is turned into a low plasma state and a high energy state is maintained, thereby inducing a discharge state in the pyrolysis furnace 110.
Further, as shown in FIG. 7, the suction nozzle 140 is equipped with a lid, and the lid is configured to rotate clockwise, for example.
Further, the containers loaded with the porous sintered ceramic balls shown in FIG. 8 are stacked in 12 stages at the center of the piping of the suction nozzle 140, and mesh materials are provided above and below the containers.
Furthermore, the containers loaded with the porous sintered ceramic balls shown in FIG. 8 are stacked one on top of the other, rotating clockwise by, for example, 15 degrees, one on top of the other.

The electromagnetic valve 150 is used to adjust the amount of negatively ionized water (water substance, water molecules, spheres) introduced into the pyrolysis furnace 110 through the suction nozzle 140 .
The electromagnetic valve 150 is, for example, a flow rate adjustment valve type electromagnetic valve, and is attached near the base end of the electromagnetic valve 150.

The temperature sensor 160 detects the internal temperature of the pyrolysis furnace 110.
As the temperature sensor 160, for example, a temperature sensor having a thermocouple structure can be exemplified, and is installed at two locations, upper and lower, inside the pyrolysis furnace 110.
The temperature sensor 160 installed above the interior of the pyrolysis furnace 110 is placed close to the upper surface of the pyrolysis furnace 110, for example, and detects the temperature of the gas G generated by thermally decomposing the organic matter P.
On the other hand, the temperature sensor 160 installed in the lower part of the interior of the pyrolysis furnace 110 is located slightly above the temperature sensor 160 installed in the upper part of the interior of the pyrolysis furnace 110, and detects the organic matter P being pyrolyzed. Detect temperature.

The controller 170 executes, for example, opening/closing control of the electromagnetic valve 150 or cooperative control with the temperature sensor 160.
The controller 170 includes a microprocessor, and controls the opening/closing degree of the opening/closing control of the electromagnetic valve 150 when it is detected from the sensor information from the temperature sensor 160 that the inside of the pyrolysis furnace 110 exceeds a predetermined temperature. Execute processing.
In this embodiment, the controller 170 is provided in the pyrolysis treatment apparatus 100, but it controls the entire organic substance pyrolysis treatment system 1, including the processing of the following devices, etc., which will be described later. It may be integrated into one central control unit.

The gas flow mechanism 180 discharges the gas G generated by decomposing the organic matter P from above the thermal decomposition furnace 110 to a gas processing device 200 described below.
Note that the gas flow mechanism 180 may be provided with a duct (not shown) that prevents the flow of gas G from diffusing and regulates the flow direction.

<Configuration of gas treatment device 200>
As shown in FIG. 1, the gas treatment device 200 has a structure in which a plurality of scrubbers 210, 220, and 230 having a wet scrubber structure are connected together, and a blower 240 is connected to the end.

The scrubber 210 uses an alkaline solution containing caustic soda to process the oxidized and decomposed gas G into gas G within environmental standard values.
The scrubber 210 also includes a high-pressure shower 211, a filling storage section 212, and a high-pressure mist shower 213. J adsorbs smoke-containing particles and odor-bearing particles on its surface, and the high-pressure mist shower 213 cleans the adsorbed substances adsorbed on the surface of the packing J.
Note that the scrubbers 220 and 230 also have the same configuration as the scrubber 210.

The blower 240 discharges the gas G that has been treated within the environmental standard value in the scrubbers 210, 220, and 230 to the outside.
The blower 240 is, for example, a multi-blade blower (sirocco fan) to which a large number of blades are attached in the direction of rotation.
The blower 240 has vertically elongated plate-shaped blades attached in a cylindrical shape, and rotates the blades to suck in air and exhaust the air.
The blower 240, which is a multi-blade blower (sirocco fan), has the characteristics of being quiet, being less susceptible to the influence of outdoor wind, and being able to be installed anywhere.

If the displacement of the blower 240 is set to 1.0 to 1.5 m ³ per minute, the amount of suction in the pyrolysis furnace 110 is determined based on the amount of air passing through the two suction nozzles shown in FIG. 3.
Furthermore, the speed of air passing through the magnetic porous ceramic ball is proportional to the suction amount of the multi-blade blower (sirocco fan).
The heated high-temperature gas sucked from the lower part of the pyrolysis furnace 110 via the diffuser pipes 117A and 117B is diffused into the pyrolysis furnace 110 at a low speed.
For example, if the capacity of the pyrolysis furnace 110 is set to 2.2 to 2.5 m ³ , control is required to maintain the temperature inside the furnace at a suction rate of 1.0 to 1.5 m 3 per minute.
Note that if oxygen is rapidly supplied, the degree of oxidation becomes severe, and the time required for reduction decreases, so care must be taken.

Further, the exhaust amount of the blower 240 needs to be controlled to a constant amount.
For this purpose, it is necessary to take into account and control the resistance (exhaust pressure resistance) of the three wet scrubbers 210, 220, and 230, the effects of organic matter P and bottom ash in the pyrolysis furnace 110, and piping resistance.
Further, it is also necessary to consider the resistance to simultaneously sucking the exhaust smoke and odor generated in the pyrolysis furnace 110 (inside the input port 111).

<Treatment water purification device 300>
As shown in FIG. 1, the treated water purification device 300 includes a circulation tank 310, an electrolyzer 320, a filter press 330, and a pump 340.

The circulation tank 310 is connected to the drainage ports of the scrubbers 210 , 220 , 230 of the gas treatment device 200 , and stores the waste water of the scrubbers 210 , 220 , 230 of the gas treatment device 200 .
The circulation tank 310 also stores water supplied from the outside or treated water that has been processed by a filter press 330, which will be described later.
The circulation tank 310 is also provided with a liquid level gauge for controlling the liquid level in the tank or a pH adjustment device for controlling the pH of the treated water stored in the tank.
In the present embodiment, the pH of the treated water stored in the circulation tank 310 can be adjusted to, for example, PH3.2 by controlling the amount of water supplied from the outside or the amount of treated water that has been processed by the filter press 330. It is managed so that the score is ~3.5.

The electrolyzer 320 includes an electric field bath, and performs processes including oxidation treatment, reduction treatment, coagulation treatment, decolorization treatment, and deodorization treatment of the treated water supplied from the circulation tank 310.

The filter press 330 separates the treated water drained from the electric field bath of the electrolyzer 320 into liquid and solid.

Pump 340 supplies a portion of the liquid separated in filter press 330 to circulation tank 310 .
Further, a portion of the liquid separated in the filter press 330 is drained to the outside.

<Processing of organic matter pyrolysis treatment system 1>
When the controller 170 detects that the organic substance P whose moisture content is controlled is input from the input port 111 provided on the upper surface of the pyrolysis furnace 110, the controller 170 operates the burner 120.

When the burner 120 is operated, the organic substance P whose moisture content is controlled is ignited and heated.
When the organic material P whose moisture content is controlled is ignited and heated, the combustion temperature of the organic material P is used to raise the temperature in the furnace.

The controller 170 operates the burner 120 and controls the electromagnetic valve 150 to open, thereby controlling negatively ionized water (water substances, water molecules, A sphere) is supplied.

The controller 170 determines whether the furnace temperature has reached the furnace temperature of normal operation based on the combustion temperature of the organic substance P, and determines whether the furnace temperature has reached the furnace temperature of normal operation. If it is determined that this is the case, the burner 120 is operated to shift the pyrolysis furnace 110 to normal operation.

When the pyrolysis furnace 110 shifts to normal operation, the controller 170 introduces oxygen (outside air) from the suction nozzle 140, and when the introduced oxygen (outside air) passes through the porous sintered ceramic balls, electrical reduction occurs. This action causes negatively ionized water (water substances, water molecules, spheres) to be filled into the furnace and reduced.
Thereby, the introduced oxygen (outside air) is turned into a low plasma state and a high energy state is maintained, thereby inducing a discharge state in the pyrolysis furnace 110.
Under the above environment, the organic matter P is thermally decomposed into water, ash (inorganic matter, carbon, etc.), and gas (carbon dioxide, hydrocarbons, etc.).
Further, since the plurality of suction nozzles 140 are directed toward the reaction region located at the lower part of the pyrolysis furnace 110, the pyrolysis of the organic matter P progresses efficiently.

When the temperature sensor 160 detects that the temperature inside the pyrolysis furnace 110 exceeds a predetermined temperature as the thermal decomposition of the organic matter P progresses, and the controller 170 receives a sensor signal from the temperature sensor 160, the controller 170: The opening degree of the suction nozzle 140 is controlled to reduce the amount of negatively ionized water (water substances, water molecules, spheres) supplied into the pyrolysis furnace 110.
Therefore, the organic matter P does not become in a combustible state due to excessive supply of negatively ionized water (water substances, water molecules, spheres) inside the pyrolysis furnace 110, and the pyrolysis treatment of the organic matter P continues reliably. be done.

The gas flow mechanism 180 discharges the gas G containing moisture generated by decomposing the organic matter P from above the pyrolysis furnace 110 to the gas processing device 200 .

When the gas G containing moisture is sent to the gas treatment device 200, the scrubbers 210, 220, 230 and the high-pressure shower 211 of the gas treatment device 200 primarily cool the oxidized and decomposed gas G and send it to the filling storage section 212. The stored filling material J adsorbs smoke-containing particles and odor-bearing particles onto its surface, and the high-pressure mist shower 213 cleans the adsorbed substances adsorbed onto the surface of the filling material J.
The scrubbers 210, 220, and 230 discharge the gas G treated within environmental standard values to the blower 240 through piping.
Further, the scrubbers 210, 220, and 230 discharge treated water generated by the cleaning process to the treated water purification device 300 through piping.

The blower 240 discharges the gas G that has been treated within the environmental standard value in the scrubbers 210, 220, and 230 to the outside.

The treated water purification device 300 stores treated water from the scrubbers 210, 220, and 230 of the gas treatment device 200 in a circulation tank 310.
The circulation tank 310 is also provided with a liquid level gauge for controlling the liquid level in the tank or a pH adjustment device for controlling the pH of the treated water stored in the tank. The pH of the treated water is managed to be, for example, PH 3.2 to 3.5 by controlling the amount of water supplied from the outside or the amount of treated water that has been processed by the filter press 330.

The electrolyzer 320 includes an electric field bath, and performs processes including oxidation treatment, reduction treatment, coagulation treatment, decolorization treatment, and deodorization treatment of the treated water supplied from the circulation tank 310.

The filter press 330 separates the treated water drained from the electric field bath of the electrolyzer 320 into liquid and solid.

Pump 340 supplies a portion of the liquid separated in filter press 330 to circulation tank 310 .
Further, a portion of the liquid separated in the filter press 330 is drained to the outside.

In addition, even if the temperature inside the furnace temporarily drops when processing objects made from organic matter P are input, based on the knowledge obtained from many demonstration experiments, the moisture content of the articles made from organic matter P will be reduced. By limiting the temperature to the determined predetermined range, the time required for the furnace temperature to return to its original value can be shortened to within the margin of error.

When the volume is reached, a second predetermined volume of new organic matter P is charged from the input port 111 of the pyrolysis furnace 110.
That is, based on the knowledge obtained from many demonstration experiments, the first predetermined volume is, for example, about 1/5 of the capacity of the organic matter P in the pyrolysis furnace 110, and the second predetermined volume is, for example, the volume of the organic matter P in the pyrolysis furnace 110. It can be set to 2/3 of the internal volume.
Therefore, in the organic substance pyrolysis treatment system 1 according to the present embodiment, the pyrolysis treatment can be performed more efficiently than before.
In addition, by limiting the moisture content of products made from organic matter P to be input to a predetermined range found based on knowledge obtained from many demonstration experiments, and by setting the input conditions, organic matter P can be increased over a certain period of time.
