Description

technical field [0001] The invention belongs to the field of chemical industry, in particular, the invention relates to a tire fast pyrolysis system and method. 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 represented by 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 oil vapor through the washing tower, and the combustible gas is sent to the burner for combustion t...
