Novel organic waste thermal decomposition device and organic waste thermal decomposition method

The embodiment of the invention provides a novel organic waste thermal decomposition device. The novel organic waste thermal decomposition device comprises a thermal decomposition chamber, a central smoke chamber, an outer wall smoke chamber and a thermal insulation layer. The thermal decomposition chamber is cylindrical, the central smoke chamber is a hollow cylinder, is concentrically arranged in the thermal decomposition chamber and can rotate under driving of a motor driver, and a spiral blade is fixedly connected to the outer wall of the central smoke chamber. The outer wall smoke chamberis arranged around the outer wall of the thermal decomposition chamber. The thermal insulation layer wraps the outer side of the outer wall smoke chamber, and a central smoke outlet is connected witha wall surface smoke inlet through a smoke pipe. Waste materials are heated on the inner side and the outer side of the thermal decomposition chamber simultaneously through the two smoke chambers, the heating area of the wast
