Description

technical field [0001] The invention relates to the technical field of pyrolysis of organic solid waste, in particular to a system for implementing the pyrolysis method of organic solid waste and the method. Background technique [0002] Thermochemical conversion (such as carbonization, pyrolysis, gasification) of organic solid waste and other viscous carbonaceous materials (such as oilfield oily sludge, mineral dust sludge, industrial sludge, hazardous waste liquid) can produce solid, liquid and gaseous states These products are made into recyclable, easy-to-use, easy-to-transport and easy-to-storage energy forms according to needs, which can be used for thermal power generation or as raw materials for chemical and other industries. Depending on the raw material and the purpose of heat treatment, carbonization, gasification, pyrolysis, liquefaction or other related thermochemical reactions and processes can be used. [0003] Pyrolysis uses many reactor forms, such as movin...

AI Technical Summary

Problems solved by technology

However, this method has the following technical problems: this process cannot deeply purify the pyrolysis gas, resulting in high impurities in the flue gas after pyrolysis gas combustion, which requires further purification, resulting in increased operating costs, and it is difficult to meet the requirements of the pyrolysis gas after amplification. The internal combustion engine requires gas quality, and the entire seal adopts a mechanical seal, which has a poor sealing effect and poses a safety hazard
