System for separating high-temperature oil gas and carbon black obtained after thermal pyrolysis of waste rubber and plastic

Abstract

The invention belongs to the field of waste rubber and plastic pyrolysis treatment, and relates to a system for separating high-temperature oil gas and carbon black obtained after thermal pyrolysis ofwaste rubber and plastic. By means of the system for separating the high-temperature oil gas and the carbon black obtained after thermal pyrolysis of the waste rubber and plastic, the technical problems that in the outputting process of the high-temperature oil gas, the carbon black is mixed in the high-temperature oil gas, and an oil gas conveying pipeline is blocked as the carbon black is accumulated for a long time are solved. The system comprises an oil spraying tower, a primary settling tank, a secondary settling tank, a circulating oil pump and a cooling tank, all of which are sequentially connected annularly. The input end of the oil spraying tower is connected with a wall scraping screw for conveying the high-temperature oil gas in a thermal pyrolysis device, the primary settlingtank and the secondary settling tank are connected with two primary carbon black storage tanks through a primary settling carbon black outlet and a secondary settling carbon black outlet respectively,and a secondary settling oil outlet of the secondary settling tank is connected with an oil drainage pump. By means of the system, no carbon black is deposited in a whole process channel of the high-temperature oil gas, and blockage is avoided; the carbon black and the high-temperature oil gas are separated, the solid carbon black and the pure high-temperature oil gas are obtained, and meanwhilespraying oil is recycled.

Description

technical field [0001] The invention belongs to the field of pyrolysis treatment of waste rubber and plastics, in particular to a high-temperature oil gas and carbon black separation system of waste rubber and plastics. Background technique [0002] With the development of the automobile industry, the demand for rubber and plastic products such as tires is increasing day by day. At the same time, the number of waste tires has also increased sharply, which has brought environmental problems. At present, there are mainly the following methods for the treatment of waste tires: landfill method, incineration method, recycling and cracking method, etc. Among them, the pyrolysis of waste tires is to crack the high polymer in waste tires at an appropriate temperature into heat Decomposition gas, pyrolysis oil, pyrolysis charcoal-based storage energy and incomplete pyrolysis process of raw materials. [0003] Thermal cracking of waste rubber and plastics is the most effective treatm...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a waste rubber and plastic high-temperature oil gas and carbon black separation system, which solves the problem that high-temperature oil and gas are inevitably mixed with a certain amount of carbon black during the output process, thereby affecting the quality of the produced oil, and the accumulation of carbon black for a long time is also difficult. It will cause blockage of oil and gas transmission pipelines, resulting in shutdown and even dangerous technical problems of leakage
