The processing body 10 is installed, for example, on a plate 3 placed on the ground. The processing main body 10 is a thermal decomposition furnace that thermally decomposes the processed material. Here, pyrolysis is different from the state in which the processed material burns by raising a flame, and the processed material is smoked while supplying a small amount of air (magnetized air), or the amount of heat originally possessed by the processed material as a steamed state. The processed product is decomposed by heat while using the above. Further, the magnetized air is air magnetized by passing through a region where a magnetic field is generated. Magnetized air is a gas that has the property of activating oxygen by magnetic force to generate a large amount of negative ions, and has the property of acting on carbon molecules of organic substances to cause a thermal decomposition reaction with organic substances. Are known.

More specifically, the processing body 10 magnetizes the outside air to generate magnetized air, and exposes the magnetized air to the processed object to thermally decompose the processed object. The processing main body 10 has, for example, a total height of about 255 cm, and is provided with a deck and stairs around it so that an operator can perform work of loading or maintaining a processed object. The size of the bottom surface of the processing body 10 is about 304 cm × 280 cm. However, the size of the processing body 10 is not limited. For example, the processing body 10 may be designed to be larger.

The electric heater 11 is a ceramic heater that generates a high temperature. The electric heater 11 further thermally decomposes the residue contained in the gas generated by the thermal decomposition in the processing main body 10. The electric heater 11 is installed on the installation table 11a.

The recirculation portion 12 is composed of a pipe connecting the processing main body 10 and the electric heater 11. The recirculation section 12 recirculates the gas generated by the thermal decomposition of the processed material in the processing main body 10 between the processing main body 10 and the electric heater 11, and discharges the gas in which the residue is thermally decomposed.

[Processing body]
The detailed configuration of the processing body 10 will be described. As shown in FIGS. 3, 4 and 5, the processing main body 10 includes a charging unit 20, a thermal decomposition unit 21, and a discharging unit 22. The material of the processing main body 10 is preferably a heat-resistant metal such as a mixture of stainless steel, iron, and 蹉 跌, an aluminum alloy, a magnesium alloy, and duralumin. The outer circumference of the processing main body 10 is covered with the heat insulating material 2.

The charging unit 20 is arranged above the processing body 10. The processed material is charged into the charging unit 20.

The thermal decomposition unit 21 is arranged at the lower part of the processing main body 10. The processed material charged into the charging unit 20 falls on the thermal decomposition unit 21. The thermal decomposition unit 21 thermally decomposes the processed material that has fallen from the charging unit 20.

The discharge unit 22 is arranged in the upper part of the processing main body 10. The discharge portion 22 is connected to the recirculation portion 12. The discharge unit 22 discharges the gas generated by the thermal decomposition of the processed material in the thermal decomposition unit 21 to the recirculation unit 12.

A wall 24 partitions the input unit 20 and the discharge unit 22. Further, the charging section 20 and the thermal decomposition section 21 are shielded by a holding section 30, which will be described later. Therefore, the gas generated by the thermal decomposition of the processed product in the thermal decomposition section 21 is discharged from the discharge section 22 to the recirculation section 12.

[Input section]
The detailed configuration of the input unit 20 will be described. As shown in FIG. 3, the input portion 20 forms an internal space 20a. The insertion section 20 is provided with a door 23. The door 23 communicates with the internal space 20a, and the processed material is thrown into the internal space 20a from the outside through the door 23.

A holding portion 30 and a weight portion 31 are provided in the internal space 20a of the charging portion 20. The holding unit 30 holds the processed material input from the outside through the door 23. Weight portion 31, the holding portion 30 and the weight of the workpiece to be held is equal to or greater than the threshold value by the holding portion 30 rotates about the rotation shaft 32, dropping the treated product to the thermal decomposition section 21.

[Pyrolysis part]
Next, the configuration of the thermal decomposition unit 21 will be described. The thermal decomposition section 21 includes a decomposition chamber 40, a partition section 41, and a magnetized air supply section 42.

The decomposition chamber 40 has a side wall 50. The side wall 50 forms a rectangular parallelepiped internal space 21a in the decomposition chamber 40. The internal space 21a communicates with the internal space 20a of the charging unit 20.

The partition portion 41 is arranged in the decomposition chamber 40. Partition part 41 has the shape of a chevron plate member is folded mountain (inverted V shape). The partition portion 41, which partitions the decomposition chamber 40 so as to face the pair of side walls 50 which is the inner wall of the decomposition chamber 40 two small rooms 40a, to 40b. The partition portion 41 is arranged in a chevron shape along the X-axis direction, and the slope formed by the plate-shaped member faces the side wall 50 in the X-axis direction of the decomposition chamber 40.

The partition portion 41 is further provided with a horizontal plate 41b. The horizontal plate 41b shields the space surrounded by the chevron-shaped member of the partition portion 41 into the upper space and the lower space. The upper space constitutes a part of the decomposition chamber 40, and the lower space communicates with the outside. A blower (not shown) that takes in outside air is provided in the space below this.

As shown in FIG. 4, a grate (expanded metal) 51 is placed in each of the two small chambers 40a and 40b. The small chambers 40a and 40b are further divided into upper and lower parts by the grate 51. The processed material that has fallen from the charging unit 20 is held on the grate 51. An electric heater (not shown) is installed on the grate 51. This electric heater serves as a source of thermal decomposition of the processed material. The processed material ashed by thermal decomposition falls under the grate 51. An ash outlet 40c is provided in the room below the grate 51. Further, in the room above the small rooms 40a and 40b, a confirmation door 40d for confirming the state of the processed material from the outside is provided.

Magnetized air supply units 42 are arranged at both ends of the decomposition chamber 40 in the X-axis direction. The magnetized air supply unit 42 supplies the magnetized air to the small chambers 40a and 40b of the decomposition chamber 40. The magnetized air supply unit 42 forms an internal space 42a partitioned from the outside air. The internal space 42a is in contact with the side wall 50 of the decomposition chamber 40. The magnetized air supply unit 42 has a plurality of first supply pipes 43 penetrating the side wall 50 that abuts on the internal space 42a.

As shown in FIGS. 3, 4 and 5, the discharge ports of the first supply pipe 43 to the small chambers 40a and 40b are two-dimensionally arranged on each of the pair of side walls 50 arranged in the X-axis direction.

The first supply pipe 43 supplies the magnetized air to the decomposition chamber 40. Specifically, the first supply pipe 43 includes a pipe portion 43a through which air passes and a magnetic field generator 43b. The pipe portion 43a communicates the internal space 42a with the decomposition chamber 40. The magnetic field generator 43b is arranged on the internal space 42a side. In the magnetic field generator 43b, a permanent magnet is housed in an annular magnet storage housing attached to the tube portion 43a. Permanent magnets are arranged at positions where different poles (N pole and S pole) or the same poles (S pole and S pole, N pole and N pole) face each other, and the magnetic field is perpendicular to the air flow. To generate. As a result, the air passing through the tube portion 43a of the first supply tube 43 is actively magnetized by the negative ionization of the magnetic field generator 43b molecules, and becomes magnetized air.

A blower 60 is provided in the magnetized air supply unit 42. The blower 60 is driven by an inverter circuit and takes in outside air into the internal space 42a. By driving the blower 60, the air sent into the internal space 42a is further sent into the first supply pipe 43.

The magnetized air supply unit 42 includes a plurality of second supply pipes 44. The second supply pipe 44 is installed in the partition portion 41. The second supply pipe 44 includes a pipe portion 44a and a magnetic field generator 44b, similarly to the first supply pipe 43. As shown in FIGS. 3, 4 and 5, the second supply pipe 44 is a discharge port for discharging magnetized air to the small chambers 40a and 40b, and is a slope of a partition 41 facing each of the pair of side walls 50. It is arranged two-dimensionally in.

In this way, the first supply pipe 43 introduces the magnetized outside air through the pair of side walls 50 of the decomposition chamber 40. Further, the second supply pipe 44 introduces the magnetized outside air through the bottom surface of the decomposition chamber 40.

Further, the first supply pipe 43 extends from the internal space 42a to the side wall 50 of the decomposition chamber 40, and its discharge port is cut obliquely so that magnetized air can be discharged downward. The same applies to the second supply pipe 44.

A hot water pipe 55 is installed inside the decomposition chamber 40. The hot water pipe 55 is designed to pass near the discharge port of the second supply pipe 44. Tap water or the like passes through the hot water pipe 55. Since the hot water pipe 55 can exchange heat with the outside, tap water becomes hot water due to the heat generated by the thermal decomposition of the processed material in the decomposition chamber 40 and is output from the decomposition chamber 40. ..

[Discharge section]
When the holding section 30 does not hold the processed material, the holding section 30 shields the charging section 20 from the thermal decomposition section 21. Therefore, the gas generated by the thermal decomposition of the processed product in the thermal decomposition section 21 flows toward the discharge section 22 and is discharged to the recirculation section 12.

[Electric heater]
As shown in FIG. 1, the electric heater 11 exposes the gas sent through the recirculation portion 12 to a high temperature of 700 ° C. or higher. As a result, residues and odorous components contained in the gas such as nitrogen oxide NOx, sulfur oxide SOx, and dioxins contained in the gas are decomposed. The electric heater 11 may also be covered with the heat insulating material 2.

[Gyre part]
As shown in FIG. 1, the circulation portion 12 includes an outward pipe 12a and a return pipe 12b.
The outbound pipe 12a sends the gas output from the processing main body 10 to the electric heater 11. The return pipe 12b returns the gas discharged from the electric heater 11 to the processing main body 10.

The return pipe 12b is further branched into a first branch pipe 12b1 and a second branch pipe 12b2. The first branch pipe 12b1 returns the gas output from the electric heater 11 to the decomposition chamber 40 of the processing main body 10. The second branch pipe 12b2 returns the gas output from the electric heater 11 to the electric heater 11. In addition, each pipe of the circulation portion 12 may also be covered with a heat insulating material.

Next, a processing procedure for operating the thermal decomposition processing apparatus 1 according to the present embodiment will be described.

As shown in FIG. 6, first, a preparatory process is performed (step S1). The power of the electric heater 11 is turned on, and the power of the electric heater 11 in the thermal decomposition unit 21 of the processing main body 10 is turned on. Further, the blower 60 is started to be driven, the outside air is taken in, and the magnetized air is supplied to the decomposition chamber 40. This is to prevent the gas from leaking to the outside without decomposing the residue by first thermally decomposing the processed material in the processing main body 10 before heating the electric heater 11 or the like.

Returning to FIG. 6, when the processed product can be processed by heating the electric heater 11 or the like, the processed product C is charged into the charging unit 20 as shown in FIG. 7 (A) (step S2). As shown in FIG. 7B, when the weight of the processed object C held by the holding portion 30 exceeds the threshold value, the rotating shaft 32 rotates and the processed object C of the holding portion 30 falls into the disassembly chamber 40. To do. At this time, as shown in FIG. 8, the processed material C is distributed into the small chambers 40a and 40b by the chevron top of the partition portion 41.

When the fall of the processed object C is completed, the rotation direction of the rotating shaft 32 is changed, and the holding portion 30 returns to the original position as shown in FIG. 7 (C). As a result, the charging unit 20 and the thermal decomposition unit 21 are in a state of being shielded from each other.

Returning to FIG. 6, when the processed object C falls on the grate 51 of the small chambers 40a and 40b, the processed object C is heated by the electric heater 11 and thermal decomposition is started (step S3). As shown in FIG. 8, the magnetized air supplied from the magnetized air supply unit 42 to the decomposition chamber 40 promotes thermal decomposition of the processed product C.

As the thermal decomposition of the processed material C progresses, gas G is generated from the processed material C as shown in FIG. This gas G is discharged from the discharge section 22 (see FIG. 3) to the circulation section 12. As shown in FIG. 9, the recirculation unit 12 sends the gas G discharged from the discharge unit 22 to the electric heater 11.

The electric heater 11 heats the gas G to about 700 degrees and decomposes the residue contained in the gas G. As shown in FIG. 9, the gas G in which the residue is decomposed by the electric heater 11 is discharged to the recirculation portion 12 again to the return pipe 12b. The gas G discharged to the recirculation portion 12 branches into two, a first branch pipe 12b1 and a second branch pipe 12b2, at the return pipe 12b. One of the gases G branched into the first branch pipe 12b1 is returned to the processing main body 10, and the heat is used as a heat source for the processing main body 10. In the first branch pipe 12b1, a part of the gas G is discharged to the outside through, for example, a deodorant and deodorant filter. The components of this gas G are CO ₂ and water vapor (H ₂ O).

Further, the other gas G branched to the second branch pipe 12b2 is returned to the middle of the outbound pipe 12a sent to the electric heater 11 and returns to the electric heater 11. The heat is used as a heat source for the electric heater 11, and the residue contained in the gas is decomposed again by the electric heater 11.

Next, the reinforcing structure of the processing main body 10 in the thermal decomposition processing apparatus 1 according to the present embodiment will be described.

As shown in FIG. 10, the processing main body 10 is basically composed of a metal plate, but the edges connecting the side walls 50, which are metal plates, are a square pipe 70 extending in the vertical direction and a square pipe extending in the horizontal direction. It is reinforced with 71. This makes it possible to improve the structural strength.

Further, in the processing main body 10, the upper portion and the lower portion are joined by screwing the angle members to each other. Therefore, the upper part and the lower part can be separated. As a result, the processing body 10 is easy to carry by disassembling the components. Therefore, the thermal decomposition treatment apparatus 1 according to the present embodiment can be carried by a truck and easily installed at an arbitrary location. A sheet member (not shown) is inserted between the angle members to prevent gas from leaking from the inside to the outside. The recirculation portion 12 can also be disassembled as needed.

The concentration of dioxins contained in the exhaust gas discharged from the thermal decomposition treatment apparatus 1 according to the present embodiment was measured. The treated product was chicken manure from chickens for egg collection. First, as a result of measuring the concentration of emitted dioxins by the method specified by the Minister of the Environment based on the provisions of Article 2, Paragraph 1, Item 4 of the Act on Special Measures concerning Countermeasures against Dioxins, the concentration was 0.0026 ng. It was -TEQ / ^{m 3.} Here, the dioxins are polychlorinated dibenzo-p-dioxane (PCDDs) and polychlorinated dibenzofurans (PCDFs).

Furthermore, the measured concentration of DL-PCBs, was 0.0021ng-TEQ / ^{m 3.} DL-PCBs refer to isomers of PCBs (polychlorinated biphenyls) that have the same toxicity as PCDDs and PCDFs. Concentration of total dioxins of the sum of dioxins and DL-PCBs was 0.0026ng-TEQ / ^{m 3.} The emission standard for dioxins in waste incinerators is 5 ng-TEC / m ³ as a reference value, and it was clarified that the measurement results were far below such emission standards.

Further, the concentrations of dust, nitrogen oxides (NOx), sulfur oxides (SOx), and hydrogen chloride (HCl) discharged from the pyrolysis treatment apparatus 1 were measured. First, when the concentration of dust was measured by the measuring method specified in JIS-Z-8808, the average concentration was 0.023 g / m ³ N. Further, when the concentration of nitrogen oxide was measured by the measuring method specified in JIS-K-0104, the average concentration was 170 ppm. Further, when the concentration of sulfur oxide was measured by the measuring method specified in JIS-K-0103, the average concentration was 44 ppm. Further, when the concentration of hydrogen chloride was measured by the measuring method specified in JIS-K-0107, the average concentration was 3.6 mg / m ³ N. All of these figures were well below the emission standards.

11 to 13 show a measurement result report of the dioxin concentration measurement of the thermal decomposition treatment apparatus 1. 14 to 17 show a measurement result report of exhaust gas measurement of the thermal decomposition treatment apparatus 1. 18 to 20 show the dioxin measurement and analysis work low temperature pyrolysis furnace exhaust gas report of the pyrolysis treatment apparatus 1.

As described in detail above , according to the thermal decomposition treatment apparatus 1 according to the present embodiment, the processing main body 10 exposes the magnetized air to promote the thermal decomposition of the processed product C, and the electric heater 11 is used. The residue contained in the gas G generated by the thermal decomposition of the processed product C is decomposed. The gas G circulates between the processing main body 10 and the electric heater 11, and the decomposition of the residue is repeated during that time. As a result, the residue contained in the gas can be reduced as much as possible to prevent harmful substances from being discharged to the outside. As a result, it is possible to prevent the generation of harmful substances and greenhouse gases.

In the present embodiment, the residue contained in the gas is decomposed by using the electric heater 11 instead of the heater using kerosene as a raw material. In this way, for example in kerosene heaters, 1 if it consumes months 4,320 liters per, because it is 1 liter = 2.51 kg in terms of CO _2, CO ₂ emissions reduction per year 130 tons, kerosene Since the amount of carbon dioxide used can be reduced by 4320 liters, the generation of greenhouse gases can be reduced accordingly.

The thermal decomposition treatment apparatus 1 according to the present embodiment has a structure in which the charging unit 20 into which the processed product C is charged and the thermal decomposition unit 21 are shielded during the thermal decomposition of the processed product C. This makes it possible to prevent the gas generated by the thermal decomposition from leaking from the charging unit 20.

Further, in the thermal decomposition treatment apparatus 1 according to the present embodiment, the processed material C dropped from the charging unit 20 is distributed to the two small chambers 40a and 40b, and the side walls 50 and the side wall 50 are assigned to the small chambers 40a and 40b. Magnetized air is discharged to the processed object C from the discharge ports two-dimensionally arranged on the slopes of the opposing partition portions 41. As a result, the magnetized air can be evenly exposed to the processed product C, so that the thermal decomposition of the processed product C can be further promoted. The outside air, which is the source of the magnetized air, can be widely taken in from the side surface and the bottom surface of the processing body 10.

Further, in the thermal decomposition treatment device 1 according to the present embodiment, the gas G in which the residue is decomposed by the electric heater 11 is circulated to the processing main body 10 and the electric heater 11. In this way, the heat generated by the electric heater 11 can be reused by the processing main body 10 and the electric heater 11, so that the thermal efficiency can be improved.

Further, in the thermal decomposition processing apparatus 1 according to the present embodiment, the processing main body 10 can be divided into upper and lower parts. As a result, it is possible to facilitate the transportation of the entire device and improve the degree of freedom in the installation location.

Further, in the thermal decomposition treatment apparatus 1 according to the present embodiment, the framework is reinforced with square pipes 70 and 71. Thereby, the mechanical strength of the device can be improved.

Further, in the thermal decomposition treatment apparatus 1 according to the present embodiment, the outer periphery of the treatment main body 10 is covered with the heat insulating material 2. As a result, the heat loss of the processing body 10 can be reduced.

Further, in the thermal decomposition treatment apparatus 1 according to the present embodiment, a hot water pipe 55 is piped in the decomposition chamber 40. As a result, the heat generated by the thermal decomposition of the processed product C in the decomposition chamber 40 converts the water flowing through the hot water pipe 55 into hot water. Hot water is used for various purposes.

If the total area of the grate 51 is 2 square meters or less, installation permission based on the standards of the Ministry of the Environment is not required.
