Description

technical field [0001] The invention belongs to the field of environmental protection chemical industry, and specifically relates to a high-temperature pyrolysis reactor and a system and method for producing oil and carbon black by pyrolyzing waste tires. Background technique [0002] At present, the pyrolysis treatment process of waste tires mainly includes catalytic pyrolysis, vacuum pyrolysis, hydrogenation pyrolysis and autothermal pyrolysis, etc., and the reactor forms adopted include moving bed, fixed bed, fluidized bed, rotary kiln, etc. Various processes have strict requirements on raw material pretreatment and particle size, and the obtained products are also different. [0003] The moving bed pyrolysis process is most representative of the vacuum moving bed of Laval University in Canada. After the waste tires are pretreated, they enter the moving bed under vacuum conditions and transfer heat through the outer wall of the moving bed. The decomposed steam captures o...
