Claims

A carbonizing furnace that pyrolyzes and wastes wastes,
A body for pyrolyzing the waste;
An exhaust unit for exhausting exhaust gas generated when the waste is pyrolyzed;
The body is
The pyrolysis furnace which is configured to be tapered toward the bottom as it goes downward,
An inlet provided at an upper end of the thermal decomposition furnace ;
A plurality of heat conduction heaters disposed in the lower part of the pyrolysis furnace;
An infrared layer formed in a layer in the thermal decomposition furnace and below the heat conduction heater;
An agitator disposed within the pyrolysis furnace and below the infrared layer;
And an ash outlet provided at the bottom of the main body,
The exhaust unit is
An upstream exhaust pipe as an upstream flow path,
A downstream exhaust pipe as a downstream flow path,
And an exhaust processor harmful substances to process the exhaust gas so as not to be exhausted,
The downstream exhaust pipe includes a lower flow passage which is a flow passage through which the exhaust gas flows downward, and an upper flow passage which is a flow passage through which the exhaust gas flows upward ,
The lower flow passage is disposed on the upstream side of the upper flow passage, and the exhaust processing unit is disposed in the middle of the lower flow passage,
The exhaust processing unit includes a plurality of electric heaters for processing the exhaust gas,
The upper flow path of the downstream exhaust pipe is longer than the lower flow path,
The lower end of the downstream exhaust pipe is located below the lower end of the thermal decomposition furnace,
The upper end portion of the downstream side exhaust pipe is located above the upper end of the thermal decomposition furnace.

An exhaust fan is disposed in the exhaust pipe and between an upper portion of the thermal decomposition furnace and the exhaust processing unit,
The exhaust fan is configured to exhaust the exhaust gas flowing from the thermal decomposition furnace into the upstream exhaust pipe of the exhaust unit to the outside through the downstream exhaust pipe and the upper flow path. The carbonization furnace according to claim 1, characterized in that

The heat conduction heater is controlled by the operation unit, and the surface of the heat conduction heater is configured to generate heat at 800 ° C.
The heat conduction heater is controlled such that the temperature of the exhaust gas flowing from the upper portion of the thermal decomposition furnace into the exhaust unit is 100 ° C. to 200 ° C. by heating the waste. The carbonization furnace according to claim 1 or 2.
