 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a longitudinal sectional view of the incinerator apparatus according to the present invention, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. 3 is a left side of the incinerator apparatus of the present invention. FIG.

In FIG. 1 and FIG. 2, a combustion furnace apparatus 1 includes a dry distillation chamber 4 having an inlet 3 into which a waste or garbage is thrown into a furnace body 2, and a lid for closing the inlet. A combustion chamber 6 for completely combusting the carbonization gas generated in the carbonization chamber 4, and a carbonization gas passage 7 communicating the carbonization chamber 4 with the combustion chamber 6. Is equipped with a ceramic filter. A plurality of outside air introduction pipes 8 for introducing outside air from the outside of the furnace main body 2 are connected to the combustion chamber 6, and the plurality of outside air introduction pipes 8 adjust the amount of outside air introduced. Adjustment valves 9 are provided respectively.

The carbonization chamber 4 includes a side wall 4a and a bottom plate 4b. Near the outside of the side wall 4a and the bottom plate 4b, a first electric heater 14 for raising the temperature of the carbonization chamber 4 is provided. A carbonization chamber temperature sensor 16 for measuring the internal temperature of the carbonization chamber 4 is also provided. Also, the bottom plate 4b of the carbonization chamber 4 is formed to have a substantially W-shape, the central portion 4c is formed in a convex shape upward, and both sides thereof are formed in a concave shape, and the inside of the carbonization chamber 4 is heated to a high temperature. When the bottom plate 4b rises, even if the inner surface of the bottom plate 4b expands, the bottom plate 4b becomes substantially horizontal and does not contact the first electric heater 14 near the bottom plate. A discharge passage 10 for discharging combustion gas from the combustion chamber 6 is connected to the combustion chamber 6, and the discharge passage 10 has an exhaust port 11 for discharging exhaust gas to the atmosphere. An outside air supply pipe 12 for forcibly supplying outside air is provided in the discharge passage 10. A blower 13 is provided in the outside air supply pipe 12, and the blower 13 is provided with an adjusting mechanism for adjusting a supply amount of the supply outside air.

In the furnace body 2, a second electric heater 15 for raising the temperature of the combustion chamber 6 to a high temperature is disposed near the combustion chamber 6, and a combustion chamber for measuring the internal temperature of the combustion chamber 6 is provided. A temperature sensor 17 is provided. The first electric heater 14 is ON / OFF controlled at 200 ° C. to 500 ° C. based on temperature detection in the carbonization chamber by the carbonization chamber temperature sensor 16, and the second electric heater 15 is provided with a combustion chamber temperature sensor 17. ON-OFF control is performed from 800 ° C. to 1000 ° C. based on the detection of the temperature in the combustion chamber.

As shown in FIG. 3, the discharge passage 10 is formed by a discharge passage expansion chamber 10 a, a discharge outlet passage 11 a having a narrowed upper portion, and a discharge port 11 for discharging exhaust gas to the outside. It is configured. The length of the discharge passage in the up-down direction is about 50 cm to 60 cm, and the entire discharge passage is configured to have a length of about 1 m.

Next, a method for incineration of waste and the like in the incinerator apparatus according to the present invention will be described. First, an input material such as waste is injected into the dry distillation chamber 4 from the input port 3, and the dry distillation chamber 4 is held in a closed state by the lid 5, and then the first electric heater 14 and the aforementioned By heating the carbonization chamber 4 and the combustion chamber 6 by the second electric heater 15, respectively, a carbonization gas is generated from the charge in the carbonization chamber 4, but outside air is supplied into the carbonization chamber 4. Therefore, combustion in the carbonization chamber 4 does not occur. At this time, since the blower 13 for supplying outside air has not been operated yet, combustion does not occur because there is no introduction of outside air into the combustion chamber 6.

After that, when the temperature in the combustion chamber 6 is increased to 800 ° C. or higher by the second electric heater 15, the operation of the blower 13 is started. Then, the air supplied from the blower 13 is supplied to the discharge passage expansion chamber 10 a and discharged from the discharge port 11. The flow of the air causes the combustion chamber 6 to enter the carbonized gas from the carbonized gas passage 7 through the carbonized gas passage 7. When the outside air is introduced from the outside air introduction pipe 8, the combustion of the carbonized gas occurs in the ceramic filter in the combustion chamber 6. Thereafter, the temperature in the combustion chamber 6 further rises due to the combustion of the carbonization gas, and complete combustion is maintained.

However, the outside air supply amount adjustment mechanism of the blower 13 and the outside air adjustment valve 9 of the outside air introduction pipe 8 are provided in advance in the combustion chamber 6 for each type of waste and trash by preliminary experiments. The opening is adjusted so that a predetermined outside air amount is introduced so that combustion is completely burned and no combustion occurs in the discharge passage 10.

Next, the exhaust gas discharged from the combustion chamber 6 is rapidly cooled by stirring and mixing with the outside air supplied from the blower 13 in the discharge passage expansion chamber 10a, and is cooled to 100 ° C. or less. Is discharged from the outlet 11 as low-temperature exhaust gas.

In the above embodiment, the embodiment as an incinerator apparatus has been described. However, by changing the control temperature of the carbonization chamber and the control temperature of the combustion chamber, the same configuration as the present invention can be used as a deodorization apparatus. It is also possible. Further, although the description has been given of the example in which the electric heater is used as the first electric heater and the second electric heater, the heating device is not limited to the electric heater as long as the heating device can heat the carbonization chamber and the combustion chamber to a predetermined temperature. Of course, a gas heater may be used.

[0017]

[Effect of the invention]

 In the incinerator device of the present invention, a blower for forcibly supplying outside air to the discharge expansion chamber formed in the discharge passage is provided, and the outside air is forcibly supplied from the blower. The exhaust gas discharged from the exhaust port can be completely cooled in the combustion chamber while being cooled rapidly by mixing the exhaust gas with the outside air. Can be a low-temperature exhaust gas of 100 ° C. or less. This has the effect that the length of the discharge passage can be made as short as 1 m or less, and the vertical height of the discharge expansion chamber and the discharge port can be made as short as about 60 cm. Further, by providing an adjusting mechanism for adjusting the amount of outside air supplied to the blower and an adjusting device for adjusting the amount of intake air in the introduction passage for introducing air into the combustion chamber, smokeless, flameless, and odorless can be further achieved. It has the effect of minimizing the generation of dust, carbon monoxide (CO), dioxin, and other harmful gases. Furthermore, the input of waste and garbage into the carbonization chamber generates carbonization gas and carbonizes in a state where oxygen is not supplied, so that the generation of carbon dioxide (CO2) is minimized. This has the effect that it can be suppressed and the residual carbide can be reused as fuel.
