Abstract

The invention belongs to the field of waste rubber and plastic thermal cracking treatment, particularly relates to a waste tire whole tire continuous thermal cracking system and method, and solves thetechnical problems that equipment investment and operation cost are increased due to the fact that the waste tires need to be crushed into blocks in a mechanical mode before thermal cracking in orderto achieve continuous thermal cracking of the waste tires in the prior art, and popularization and application of the thermal cracking technology of the waste tires are limited, the system sequentially comprises a U-shaped preheating box, a thermal cracking reactor and a condensing system which are connected in a ring manner, wherein the continuous thermal cracking system and method for the wholewaste tire achieve the continuous thermal cracking of the whole waste tire without crushing the waste tire into blocks, the production cost is reduced, the waste tires are preheated by using the heating tail gas and the heat of heavy oil, the heat source is recycled, the energy consumption is reduced, the heavy oil is used as a heating medium, the secondary cracking of the heavy oil and conversion of the heavy oil into the light oil with higher economic value are achieved, and the technical popularization adaptability is improved.

Description

technical field [0001] The invention belongs to the field of pyrolysis treatment of waste rubber and plastics, and in particular relates to a continuous pyrolysis system and method for whole waste tires. Background technique [0002] With the rapid development of the automobile industry, the storage of waste tires in my country is increasing, and the huge amount of waste tires is putting more and more pressure on the environment. Waste tires are difficult to degrade due to their strong heat resistance and mechanical resistance. Direct stacking not only takes up land, but also is prone to fire. How to recycle, reduce, and harmless waste tires to prevent environmental pollution is not only a worldwide problem, but also with the shortage of raw material petroleum and natural rubber resources in the tire industry, the recycling and utilization of waste tires is also related to the sustainable development of the world It is also a new issue in the utilization of renewable resourc...
