Problems solved by technology

However, the purity of the product obtained by treating waste plastics in this way needs to be improved; the heating device used in the system is an induction variable frequency heater, that is, a thyristor is used to generate intermediate frequency for heating, so this system is in use. There are problems of high energy consumption and high noise during its operation

Abstract

The invention relates to a reduction method and a reduction system for processing waste plastics. The method and the system take an IGBT heating module as the core, and can save over 40 percent of energy compared with the prior vacuum tube high-frequency equipment and the prior thyristor induction heating equipment. The method and the system adopt the novel catalytic pyrolysis method, namely the prior mode of directly placing catalyst zeolite into the waste plastics is changed and the waste plastics are gasified into oil gas and then degraded by Y-shaped molecular sieves. Therefore, the pyrolysis effect of the method and the system is more obvious; the quality of liquid fuel gasoline and diesel fuel produced is better; and the gasoline and the diesel fuel produced reach or exceed the national standards of No.70 gasoline SHO 42-92 and No. 0 diesel fuel GB 252-94. Moreover, No. 90 to No. 93 unleaded gasoline can be modulated by utilization of the gasoline.

Description

technical field [0001] The invention relates to a reduction method and system for treating waste plastics. Background technique [0002] With the development of society, plastics and their products occupy an extremely important position in the national economy. Whether it is in the defense industry, transportation, machinery manufacturing, agricultural medicine and health, or in people's daily life, it has a wide range of uses. It is estimated that plastic products based on petroleum, coal and natural gas will account for 70% of the world's petrochemical products in this century. With the development of these industries and the huge increase in output, the pollution of their wastes to the environment has gradually become a major public hazard to the human living environment. At present, the pollution caused by plastic waste in major and medium cities in the world is very serious. Due to the use of ground film in farmland, it also causes pollution to farmland. Governments...
