Scope

Scope: This document specifies the terms and definitions, as well as technical requirements, for the design of high-efficiency reactors that utilize thermal pyrolysis to achieve the recycling and recovery of solid waste from discarded tires. This document applies to the design and optimization of rotary kiln reactors for the efficient pyrolysis of solid waste such as crushed waste tires. Main technical content: 3.1 Waste tires are tires that have lost their original use value and cannot be repaired for continued use. 3.2 Waste tire pyrolysis is the process of pyrolyzing waste tires in an oxygen-free or inert gas environment to produce regenerated oil, pyrolyzed carbon black, and recovered steel wire from waste tires, as well as non-condensable combustible gases. 3.3 Pyrolyzed carbon black is the carbon-rich solid product generated during the pyrolysis of waste tires. 3.4 Design criteria for continuous rotary kiln waste tire pyrolysis reactors refer to the general term for the design and optimization of rotary kiln reactors for the efficient pyrolysis of waste tires. 3.5 Effective aspect ratio is the ratio of the effective length to the effective diameter of a rotary kiln pyrolysis reactor. 4 Technical requirements Reactor main body effective aspect ratio design calculation (1) Analysis of waste tire pyrolysis degree The pyrolysis conversion rate of waste tires refers to the ratio of the mass of waste tires that undergo decomposition reactions due to heating to the mass of the material before the reaction. Since the changes occur due to the decomposition reaction of waste tires, the pyrolysis conversion rate is mainly related to factors closely related to the decomposition reaction, such as pyrolysis temperature and reaction time. Due to the differences in the rubber composition of different types of waste tires, it is necessary to select the optimal pyrolysis temperature for the decomposition of waste tires. The selection of the optimal pyrolysis temperature can be
