Title:
SYSTEM AND PROCESS OF INDUSTRIAL CONTINUOUS CRACKING OF MIXED WASTE PLASTICS ACCORDING TO CLASS
Document Type and Number:
WIPO Patent Application WO/2022/067882
Kind Code:
A1
Abstract:
The present invention relates to a system and process of industrial continuous cracking of mixed waste plastics according to class, the system comprising: an extrusion dryer; first and second stage lifting screw conveyors; a catalytic mixing cylinder; a semi-plasticizing feeder; first, second and third stage cracking reaction furnaces; slag discharging first, second and third stage screws; a separator; a slag storage tank; first, second and third basket-type filters; first, second and third stage settling towers; air-cooling first, second and third heat exchangers; water-cooling first, second and third stage heat exchangers; first, second and third stage gas-liquid separation tanks; first, second and third oil tanks; a non-condensable combustible gas purifier; a tail gas treatment module; a combustion chamber; and a combustor. In the present invention, according to the characteristics of different types of plastic and different cracking temperatures, a method for cracking mixed plastics according to class is provided, and the economic value added of the product of cracking is increased by independently recycling a cracked oil product; in addition, energy consumption during the cracking process is reduced by means of the recycling combustion of non-condensable combustible gas and the recycling of high-temperature waste heat, and waste gas passes through multiple purification steps, thus preventing environmental pollution.
