ABSTRACT:
A thermal decomposition system is disclosed which can decompose wastes thermally in a continuous manner and which is therefore superior in its working efficiency. In the thermal decomposition system, wherein wastes to be treated are charged into a crucible and the crucible is heated while holding the interior thereof in vacuum to decompose the wastes thermally, both ends of a rotary furnace are supported rotatably by a frame, and drive units for rotating the rotary furnace are provided. The crucible, which is cylindrical, is installed in a central axis direction of the rotary furnace and a spiral groove is formed axially in an inner wall of the crucible. A heating device for heating the interior of the crucible is installed within the rotary furnace. Both opening ends of the crucible are connected to a feed box and a discharge box, respectively, which are supported by the frame. Shutter devices are installed in the feed box and the discharge box, respectively, to shut off the interior of the crucible from the exterior. The discharge box is connected to a suction device which evacuates the interior of the crucible and which causes gases produced during decomposition of the wastes to be discharged from the crucible by suction.
