Abstract

The invention relates to a structure and method for preventing and removing inner wall coking. The following equipment is used: the equipment comprises a cracking reaction kettle,; a first intermediate shaft and a second intermediate shaft are rotatably installed in the cracking reaction kettle; a first helical blade is arranged at the periphery of the first intermediate shaft; a second helical blade is arranged at the periphery of the second intermediate shaft; a solid heat conduction ball is arranged in the cracking reaction kettle; a high-temperature gas inlet, a feeding hole, a discharginghole and a high-temperature gas outlet are formed in the cracking reaction kettle; the rotating directions of the first spiral blade and the second spiral blade are opposite. The structure is simple,high in practicability, low in manufacturing cost, beneficial to cost saving and capable of achieving a good removing effect on coking on the inner wall of the reaction kettle, and thereby increasingthe utilization rate of raw materials.

Description

technical field [0001] The invention belongs to the technical field of rubber cracking, and relates to a structure and a method for preventing and removing inner wall coking. Background technique [0002] The rapid increase in the number of automobiles and the vigorous development of the rubber industry have brought about a huge amount of waste tires. Improper disposal will cause serious pollution to the environment and threaten the survival of human beings. The waste rubber can be completely decomposed by the cracking method, and the products such as fuel oil, gas, carbon black, steel wire, etc. can be used, which not only realizes the regeneration of resources, but also solves the pollution problem. Therefore, pyrolysis technology is an important method and direction of waste rubber recycling. Catalytic cracking technology is widely used in industrial continuous production because of its low cracking temperature, low impurity content in cracked products, low energy consum...
