Pyrolysis equipment and pyrolysis method for organic waste

摘要

PROBLEM TO BE SOLVED: To provide a pyrolysis apparatus capable of suppressing oxidation of recovered carbides. SOLUTION: A pyrolysis device A has a cylindrical dry distillation tank 1 for carbonizing waste plastic WP as organic waste while moving it, a charging device 3 for charging waste plastic WP into the dry distillation tank 1, and a dry distillation tank 1. It is provided with a heating furnace 2 that covers the carbonization tank 1 and heats the carbonization tank 1 by combustion, and a recovery device 4 that recovers the carbonized material CB generated from the thermal decomposition of the waste plastic WP by heating. The charging device 3 includes a first screw pump 31, and in the first screw pump 31, the waste plastic WP pumped by the rotation of the screw 31b is degassed by the rotation pressure of the screw 31b, and air (oxygen) is removed. The pump is transferred into the outer cylinder 31c and charged into the dry retaining tank 1. [Selection diagram] Fig. 1
