First, in the present invention, the heating burner 5 is stopped when the carbonization of the waste material F inside the inner container 1 is almost completed.

Since the amount of air introduced into the inner container 1 is only a small amount corresponding to the suction capacity of the suction means 9 as compared with the capacity of the inner container 1, it remains inside the container 1. Oxygen is insufficient in terms of the total amount of carbides, and as a result, the residual carbides do not start to burn at once. That is, inside the container 1, the lower part of the residual high-temperature carbide comes into contact with the outside air to be introduced and begins to partially burn, but the upper carbide does not burn due to lack of oxygen, and the lower carbide partially burns. Due to the heat generated by, the upper carbide is further thermally decomposed to generate a pyrolysis gas.

EFFECTS OF THE INVENTION The present invention is as described above. Conventionally, even if thermal decomposition treatment is performed in a closed container, it has been difficult to handle and treat residual carbonized carbide that remains as carbide in the container. At the stage when the waste material is carbonized, heating from the outside is stopped and air is sucked in from the outside by applying suction force to the processing tank, and at the same time the carbonized material is partially burned to reduce the volume. , The pyrolysis proceeds further to the unburned carbides by the heat of this partial combustion to generate a combustible gas, and the generated gas is guided to the outside by the suction force and is not collected or discharged to the outside. Since it can be smokeless and odorless treated by burning in a container, it is extremely economical as a method of treating waste material that can be carbonized by thermal decomposition, and the treatment mode is rational, so it is extremely useful in industry. That.
