Abstract

The invention discloses a low-temperature plasma waste gas purification device and purification method. The purification device comprises a barrel body with a purification cavity body, a filter layer, a first photocatalytic oxidation mechanism, a low-temperature plasma reactor and a second photocatalytic oxidation mechanism, wherein the filter layer, the first photocatalytic oxidation mechanism, the low-temperature plasma reactor and the second photocatalytic oxidation mechanism are sequentially arranged in the purification cavity body in the paint spraying waste gas flowing direction. The first photocatalytic oxidation mechanism comprises a first ultraviolet lamp layer and a first photocatalyst layer which are sequentially arranged; the second photocatalytic oxidation mechanism comprises a second ultraviolet lamp layer, a second photocatalyst layer and a third ultraviolet lamp layer which are sequentially arranged. The low-temperature plasma waste gas purification device can sequentially perform filtration treatment, photocatalytic pretreatment, oxidative degradation treatment and photocatalytic deep treatment on paint spraying water gas. According to the low-temperature plasma waste gas purification device, on one hand, photocatalysis and a low-temperature plasma technology are combined to improve efficiency of purifying paint spraying waste gas; on the other hand, ultraviolet lamp and photocatalyst sequences are set in the photocatalytic pretreatment and deep treatment to be matched with the low-temperature plasma reactor; thus, paint spraying waste gas treatment efficiency is further improved.

Description

technical field [0001] The invention relates to waste gas purification technology, in particular to a low-temperature plasma waste gas purification device and a purification method. Background technique [0002] In the spraying industry, the "wet production process" is generally adopted, that is, the resin is formulated into a glue with an organic solvent, and then the paint is evenly covered on the surface of the workpiece through the spray gun by the oil supply system, and then leveled and dried. Because the organic solvent in the paint contains a large amount of volatile organic gases with benzene, toluene, xylene, etc. as the main components. In the process of leveling and drying, a large amount of volatile organic gases will be volatilized. If the volatilized volatile organic gases are directly discharged from the spray booth, they will mix with the air and quickly spread to the surrounding environment of the production operation site middle. [0003] Since the main c...
