Abstract

The invention discloses a rapid tire pyrolysis system and a rapid tire pyrolysis method. The system comprises a steel wire drawing machine, a grinder, a rapid pyrolysis reactor, a cyclone separator, a slag cooler and a spray tower, wherein the rapid pyrolysis reactor comprises a reactor body, a multi-layer heat storage type radiating tube, a rubber particle inlet, a distributor, a distribution gas inlet, a plurality of pyrolysis gas outlets and a carbon black outlet; the steel wire drawing machine is suitable for drawing a steel wire in a tire; the grinder is connected with the steel wire drawing machine; the cyclone separator is connected with the pyrolysis gas outlets; the slag cooler is connected with the cyclone separator; the spray tower is connected with the cyclone separator and is suitable for spraying purified pyrolysis gas by using cooling liquid in order to obtain pyrolysis oil and fuel gas. According to the system, the utilization value of a waste tire can be maximized, the particle size of an obtained carbon black product is smaller, and subsequent grinding is not needed.

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...
