[0002] Biomass thermal cracking (also known as pyrolysis or cracking) usually refers to the process in which biomass is heated in an oxygen-free or low-oxygen environment to cause molecular decomposition to produce coke, condensable liquids and gaseous products. It is an important form of biomass energy utilization;

[0003] The composition and content of domestic waste are also tending towards urbanization. At the same time, the amount of domestic waste generated in rural areas is also increasing year by year. In the face of rural domestic waste treatment, it is now popular to use anaerobic pyrolysis treatment devices for treatment. Among them, the pyrolysis technology under high temperature and anaerobic environment is a new type of domestic waste treatment method proposed to address the defects of "incineration power generation" and the requirement of "maximizing resource utilization". For example, the application number is: CN202021256552.6, and the name is: an anaerobic pyrolysis treatment device for domestic waste, comprising a feeding system for pre-treating the raw materials and dividing them into a first material and a second material; a carbonization pyrolysis system for pyrolyzing the raw materials transported by the feeding system; the carbonization pyrolysis system comprises a carbonization furnace and a pyrolysis furnace, the carbonization furnace comprises a carbonization part and a carbonization heating jacket, and the pyrolysis furnace comprises a pyrolysis part and a pyrolysis heating jacket; a pyrolysis gas purification system for purifying the gases generated by the carbonization furnace and the pyrolysis furnace; and a combustion system for using the gas purified by the pyrolysis gas purification system to provide the heat required for the reaction of the carbonization furnace and the pyrolysis furnace.
