And a cylindrical end cover 7 that shields the supply port 6, a discharge-side cylindrical end cover 9 that shields the discharge port 8 that is the other end (the right end in FIG. 1), and the supply port 6 side. And a carbonaceous material supply section 10 that extends through the end cover 7 of the above into the drum 5. The both end covers 7 and 9 are respectively fixed to the ends of the drum 5 in the non-rotating state by the outer ends of the drum 5 in the X-axis direction, and the drum 5 has the plurality of rollers 4 and 4 shown in the drawing. It is driven to rotate around the drum axis X by being driven to rotate by a motor. Further, the supply unit 10 is configured to supply carbonaceous material to the supply port 6 from a hopper or the like (not shown). The carbonized material obtained by carbonizing the carbonaceous material is stored in the end cover 9 on the discharge port 8 side. It is designed to be discharged from a discharge part (not shown) connected below. Further, a smoke exhaust lead-out pipe 11 is connected to the top of the exhaust port side end cover 9, and the smoke exhaust in the drum 5 is led to the smoke exhaust treatment device 12 to be separated into gas and liquid, which is useful for wood vinegar or the like. It is designed to recover the components.

The incinerator 2 is provided with an incinerator body 13 arranged adjacent to the carbonization furnace 1 and an introduction part 14 for introducing waste for incineration into the incinerator body 13. The wastes such as old tires, wood chips, and garbage carried in by the introduction section 14 are incinerated in the incinerator body 13. That is, as shown in detail in FIG. 2, an example of the introduction unit 14 is a storage unit 16 for storing the waste 15 carried in by a dump truck or the like, and the waste 15 from the storage unit 16 to the incinerator. It is equipped with an overhead crane 17 having a bucket for transporting it into the main body 13, and the incinerator main body 13 incinerates the waste that has been carried in in response to the carbonization treatment in the carbonization furnace 1. ing.

Further, in the combustion gas introduction pipe 3, the upstream end 3 a penetrates the upper end of the incinerator body 13, and the downstream end 3 b penetrates the supply port side end cover 7 of the carbonization furnace 1 to form the supply port 6. They are communicated with the inside of the drum 5 via the respective vias. The carbonization furnace 1 is positioned higher than the upper end of the incinerator body 13, and the combustion gas is flown through the combustion gas introduction pipe 3 by the ascending flow of the combustion gas in the incinerator body 13.
