Document Type and Number:
WIPO Patent Application WO/2022/156454
Kind Code:
A1
Abstract:
An apparatus for pyrolyzing and gasifying sludge-coupled biomass; the apparatus comprises a feeder (1), a screw motor (2), a furnace body motor (3), a pyrolysis and gasification cavity (4), a screw pusher (5), a combustion heat supply cavity (6), an induced draft fan (7), a carbon collection box (8) and a mesh-shaped discharge port (9); an outlet of the feeder (1) is located at an inlet of the front end of the screw pusher (5), and is connected to the pyrolysis and gasification cavity (4); the screw motor (2) is connected to the screw pusher (5); the furnace body motor (3) is connected to the furnace body of the pyrolysis and gasification cavity (4); the pyrolysis and gasification cavity (4) is in communication with the combustion heat supply cavity (6) by means of the mesh-shaped discharge port (9); several stable combustion nozzles (11) uniformly distributed are provided on the side face of the inner wall of the combustion heat supply cavity (6), several air holes (10) are provided on the inner wall of the top of the combustion heat supply cavity (6), and the outer wall of the top of the combustion heat supply cavity (6) is connected to the induced draft fan (7); the carbon collection box (8) is located below the combustion heat supply cavity (6), and is connected to the combustion heat supply cavity (6) by means of a sealing wall; and an opening is provided at the connection of the carbon collection box (8) and the bottom of the pyrolysis and gasification cavity (4). The apparatus can improve the quality of the generated carbon product, ensure the performance of the carbon product, enhance the solidification of the heavy metal, and greatly increase the resource utilization rate.
