Description

A new type of UV waste gas treatment device for paint spraying room

technical field

The utility model relates to a waste gas treatment device, in particular to a novel UV waste gas treatment device for a paint spray booth.

Background technique

The painting process is widely used in containers, machinery manufacturing, electrical equipment, home appliances, automobiles, ships, furniture and other industries. The exhaust gas produced by spray painting is mainly composed of volatile solvents, thinner molecules and non-volatile paint mist molecules. At present, most of the exhaust gas treatment in the paint spray booth uses the adsorption method. The most widely used adsorption method is activated carbon as the adsorbent, which has a large surface area and is a better choice for purifying organic waste gas. However, there are problems when using activated carbon to treat spray paint exhaust gas: the paint mist particles contained in spray paint exhaust gas are small, high viscosity, and easy to adhere to the surface of the material. When activated carbon is used to absorb and recover organic solvents, the paint mist particles can easily block the pores of activated carbon. It affects the adsorption efficiency and service life of activated carbon, so UV photo-oxygen catalysis for waste gas treatment has become the mainstream, but the existing UV waste gas treatment device does not pretreat the waste gas, especially the waste gas generated by the paint spray room contains a large amount of paint mist After the particles are removed, UV photolysis can be performed, which can improve the treatment efficiency of waste gas, reduce waste gas emissions, and reduce environmental pollution.
