Description

technical field [0001] The invention belongs to the technical field of solid waste recycling. More specifically, it relates to a device for recycling waste toner cartridge toner, that is, a device for producing fuel oil and gas by pyrolyzing waste toner cartridge toner. Background technique [0002] With the accelerated development of electronic information, printers, copiers and fax machines are constantly updated. Toner cartridges are the most frequently replaced consumables, and the number of discarded toner cartridges reaches 75 million per year. The residual amount of toner in a used toner cartridge can reach 7.8%, so there is a large amount of residual toner to be disposed of. Carbon powder is a powder with a particle size of 5-12 μm, and its main components are polyacrylate-styrene, polyethylene / polypropylene paraffin, hydroxyaromatic acid derivatives, ferric oxide, silicon dioxide, etc. Among them, polyacrylate-styrene, polyethylene / polypropylene paraffin, and hydr...
