Organic waste gas recovery and treatment system and method

Abstract

An organic waste gas recovery and treatment system includes a filter box, an adsorption device and a catalytic oxidation device. After organic waste gas passes through the filter box, particles and dust are removed, and then the waste gas enters an adsorption device and is adsorbed and purified by activated carbon filled on both sides; the adsorbed gas can be directly up to the standard and is discharged; after the adsorption of activated carbon is saturated, organic waste gas is desorbed and regenerated by hot air, and the desorbed high-concentration organic waste gas enters a catalytic oxidation device and is subjected to catalytic oxidation treatment. With filtration, activated carbon adsorption and catalytic oxidation devices, the waste gas treatment can be safe and reliable, the treatment efficiency is high, and no production of secondary pollution exists. In addition, honeycomb activated carbon usually needs to be replaced 8000 h later, and the system has low use cost and maintenance cost.

Description

technical field [0001] The invention belongs to the field of waste gas treatment, and in particular relates to a paint spraying waste gas recovery and treatment system and method. Background technique [0002] A certain amount of organic waste gas is produced during painting. If these organic waste gases are not treated and discharged directly, they will pollute the environment, pollute the outdoor atmosphere, and affect people's health. Therefore, the emitted waste gases must be collected and properly treated, and then discharged at high altitudes after being harmless. [0003] There are many kinds of organic waste gas pollutants with different characteristics, so the corresponding treatment methods are also different. Commonly used are: condensation method, absorption method, adsorption method, biological method, catalytic oxidation method, etc.; in recent years, foreign countries have also developed Some new technologies: biological method, low-temperature plasma method,...

Problems solved by technology

If these organic waste gases are not treated and discharged directly, they will pollute the environment, pollute the outdoor atmosphere, and affect people's health. Therefore, the emitted waste gases must be collected and properly treated, and discharged at high altitudes after being harmless.

[0003] There are many kinds of organic waste gas pollutants with different characteristics, so the corresponding treatment methods are also different. Commonly used are: condensation method, absorption method, adsorption method, biological method, catalytic oxidation method, etc.; in recent years, foreign countries have also developed Some new technologies: biological method, low-temperature plasma method, etc., all of the above methods have certain limitations when used alone
