The waste plastic raw material is characterized by solid property, low density, low garbage classification popularization rate, small number of single sources, complex sources and relatively dispersed geographical range, so that the form of a chemical recovery plant can be a large plant with annual output of hundreds of thousands of tons, and a small plant with several tens of thousands of tons, the product of the large plant is usually olefin monomer or polymer, and the product of the small plant is usually pyrolysis oil or wax oil, and the plastic pollution problem can be better solved.
The chemical recovery of waste plastics is a process of generating intermediate chemicals such as oil, gas, carbon and the like by a series of chemical reactions on plastic wastes, and the chemical recovery method of the thermal cracking method of the waste plastics is a chemical method of finally generating combustible gas, liquid oil and solid carbon by heating and decomposing solid organic matters under the condition of isolating oxygen; the waste plastic catalytic cracking method is to add a catalyst based on the thermal cracking method, and the chemical process is to combine thermal cracking and catalytic cracking, so that the reaction rate is high, the time is short, more isomerization and aromatization products are produced in oil products, the oil quality is high, and compared with the thermal cracking of waste plastic, the catalytic cracking method has the obvious advantages of high reaction rate, low reaction condition, high product value and the like. Under the condition of reaching the same conversion rate, the reaction temperature can be obviously reduced by adding the catalyst, and the reaction temperature can be further reduced along with the increase of the catalyst-oil ratio; the shape-selective action of the cracking catalyst can also improve the product distribution, so as to obtain a product with shorter carbon chain; the catalytic cracking reaction speed is also much faster than the thermal cracking reaction.
The centrifugal scraper film-forming thermal cracking reaction device has strong adaptability, can completely crack polymers such as gas oil, oil residue, waste plastics and the like, has no discharge of thick oily matters and wax-like coke residues in the cracking process, does not cause carbon formation in equipment, is fast in heat transfer, and has no secondary pollution, and the end product is dry chemical products, namely carbon black powder. The cracking of waste plastics is especially characterized by high oil conversion rate, 100% conversion into gasoline, diesel oil, paraffin wax and carbon black, more outstanding performance, and solves the problems of long reaction period, incomplete cracking reaction, serious carbon formation, sticky coking of end products, secondary pollution caused by difficult cleaning and the like of the existing domestic and foreign waste plastic treatment equipment, and the worldwide problem of harmless treatment of the waste plastics.
The thermal cracking equipment in the oil refining system for recycling waste plastics through catalytic cracking is generally vertical thermal cracking equipment, the rotary scraping plate in the vertical thermal cracking equipment scrapes waste plastics heated into paste into films on the inner side wall of the vertical thermal cracking equipment, so that the heating element on the outer side wall of the vertical thermal cracking equipment is convenient for carrying out thermal cracking on the waste plastics films, the situation that the waste plastics films attached to the inner side wall of the vertical thermal cracking equipment are thin upwards and thick downwards can occur due to the action of gravity, the situation that the lower films are insufficient in thermal cracking when the thermal cracking of the films on the upper part of the vertical thermal cracking equipment is completed can be caused when the thermal cracking is carried out, the situation that glue is formed on the lower part of the inner side wall of the vertical thermal cracking equipment can occur after a long time, and carbon powder after the inner side wall of the vertical thermal cracking equipment is difficult to clean, and the production efficiency is further influenced; and the reforming reaction equipment in the existing waste plastic catalytic cracking recovery oil refining system is usually arranged as a catalytic reforming path, and when overhauling, the whole production line is stopped for overhauling, so that the production progress is influenced, and the production efficiency is reduced.
