Low-temperature industrial continuous catalytic cracking equipment for waste organic polymer materials

Abstract

The invention discloses low-temperature industrial continuous catalytic cracking equipment for waste organic polymer materials. The low-temperature industrial continuous catalytic cracking equipment comprises dehydration drying devices, a cracking device, a heat-conducting medium recovery device, a cracked carbon recovery device, a pyrolysis gas condensing device, a pyrolysis gas recycling combustion device, a flue gas circulating system and a flue gas treatment device which are connected in sequence. The dehydration drying devices comprise a dehydration drying device a and a dehydration drying device b. The cracking device is mainly composed of three stage of crackers, and each stage of cracker comprises a large spiral conveying mechanism, a heat supply mechanism, a heat preservation mechanism, a machine barrel, a sealing mechanism, a transmission mechanism and the like. Free conveying and cracking processes of a waste organic polymer material in cracking can be realized, and conveying of the material is forcibly realized among all stages of cracking reactors through conveyors. The equipment is reasonable in structural design, the production efficiency can be improved, dust pollution is isolated, and automatic production is achieved.

Description

technical field [0001] The invention belongs to the technical field of solid waste recycling, in particular waste rubber, waste plastics and other polymer compound wastes, and specifically relates to a low-temperature industrial continuous catalytic cracking method and equipment for waste organic polymer materials. Background technique [0002] At present, waste organic polymer materials refer to organic polymer materials such as waste plastics, waste rubber, oil sludge, coal tar, etc. With the rapid development of my country's economy, a large number of waste organic polymer materials are generated every year. Taking rubber and plastics as an example, according to statistics, the consumption of rubber and plastics in 2017 was about 13 million tons and 77 million tons respectively, and a large amount of waste rubber and plastics were produced at the same time. In 2017 alone, there were more than 300 million waste tires (12 million tons) and 25 million tons of waste plastics ...
