Background art:
plastics are high molecular compounds (macromolecules) which are polymerized by addition polymerization or polycondensation reaction and are intermediate in deformation resistance between fibers and rubber, and are composed of synthetic resin, fillers, plasticizers, stabilizers, lubricants, pigments and other additives. The main component of the plastic is resin, the resin refers to a high molecular compound which is not mixed with various additives, and the resin accounts for about 40-100% of the total weight of the plastic. The basic properties of plastics are largely determined by the nature of the resin, but additives also play an important role. Some plastics consist essentially of synthetic resins, with no or little additives, such as plexiglas, polystyrene, etc. Plastics are widely used in various technical fields, particularly packaging, building construction, automobiles and electronic and electrical appliances, because of their excellent durability, corrosion resistance, easy plasticity, stability, and the like.
Plastics bring convenience to the human society and also cause many environmental problems, and the amount of plastic waste is increasing year by year. Plastics are one of the most difficult to degrade materials in nature, and more than 60% of waste plastics are eventually subject to landfill and incineration due to lack of suitable disposal means. However, plastic landfill occupies a large amount of limited cultivated land, which seriously wastes land resources, and causes the landfill to become a soft foundation which is difficult to recycle. The plastic garbage is difficult to decompose in a short time, and the harmful substances generated in the decomposition process can cause great pollution to soil and water resources. How to efficiently treat waste plastics without pollution and realize the recycling of resources has great significance for solving the problem of domestic waste plastic garbage treatment. The thermal cracking of waste plastics is carried out by heating the plastics to a certain temperature in the absence of air. During thermal cracking, plastic waste is converted into petrochemical feedstocks, such as naphtha, liquid and waxy hydrocarbons, and the like. The thermal cracking recovery method has higher requirements on raw materials and higher operation cost, and has advantages in secondary pollution control, landfill treatment and resource utilization rate.
Before the waste plastics are subjected to thermal cracking, a series of cleaning operations are required, so that useless impurities in the materials can be removed conveniently, the cleaned plastics contain a large amount of water, and if the waste plastics are subjected to direct thermal cracking treatment, a large amount of water is contained in a cracking product, so that the quality of the cracking product is reduced seriously. Therefore, the pretreatment operation for dehydration is particularly important for thermal cracking of waste plastics.
