Efficient plastic melting cracking flue gas desorption separation purification system

Abstract

The present invention discloses an efficient plastic melting cracking flue gas desorption separation purification system, which comprises a flue gas, dust and tar water-washing removal section, a gas decomposition purification section, an oil-water separation section capable of collecting and separating oil-water debris, and an oil-water debris discharge pipeline, wherein the left end and the right end of the oil-water debris discharge pipeline are respectively connected with the flue gas, dust and tar water-washing removal section and the oil-water separation section, and the upper portion of the flue gas, dust and tar water-washing removal section is connected with the gas decomposition purification section through a flue gas pipeline. With the efficient plastic melting cracking flue gas desorption separation purification system, the problem that the existing waste plastic recovery process can produce harmful gas so as to pollute the environment can be solved. The efficient plastic melting cracking flue gas desorption separation purification system has characteristics of simple structure, low energy consumption, complete separation effect, low discharged flue gas temperature, no harmful gas production, and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and in particular relates to a high-efficiency plastic melting and cracking flue gas analysis, separation and purification system. Background technique [0002] With the continuous strengthening of people's awareness of environmental protection, waste plastics have been well recycled. At present, the recovered waste plastics are generally washed with water first, dried after cleaning, and finally heated and melted. The melted waste plastics are extruded through a plastic extruder, and then traction granulated. This treatment method will produce a large amount of high-temperature flue gas that pollutes the environment during the melting process. It is the main source of air pollution in plastic waste recycling factories, and it is also one of the biggest obstacles for such factories to obtain environmental assessment from the environmental protection department. ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a high-efficiency plastic melting and cracking flue gas analysis, separation and purification system, which aims to solve the problem that the harmful gas generated in the waste plastic recycling process will pollute the environment. The high-efficiency plastic melting and cracking flue gas analysis, separation and purification system has a simple structure. Low energy consumption, complete separation effect, reduced waste gas treatment cost, enhanced environmental protection effect, and the temperature of the discharged flue gas is low, no harmful gas will be produced, and it is more environmentally friendly
