Description

Technical Field

[0001] The utility model relates to the technical field of VOCs waste gas collection and treatment, in particular to a VOCs organic waste gas collection and treatment device for aluminum single plate painting. Background Art

[0002] The collection and treatment of VOCs (volatile organic compounds) is an important task in the field of environmental protection. It involves removing VOCs from waste gases generated in many industries such as industrial production, coating, printing and chemical industry.

[0003] The VOCs organic waste gas from common aluminum veneer painting generally needs to be filtered when it is discharged. By installing ultraviolet lamps in the exhaust duct, the VOCs organic waste gas is treated by photocatalytic oxidation, and activated carbon is installed at the outlet to treat the VOCs organic waste gas by activated carbon adsorption. However, since the VOCs organic waste gas is only photocatalytically oxidized in the pipeline, and the flow rate of the VOCs organic waste gas in the pipeline is relatively fast, the ultraviolet irradiation time of the VOCs organic waste gas is relatively short, making it difficult to catalytically treat the VOCs organic waste gas. At the same time, due to the long-term adsorption of VOCs organic waste gas by activated carbon, a large amount of organic matter will remain on the surface of the activated carbon, and the activated carbon needs to be replaced. When it is replaced, the treatment of the VOCs organic waste gas needs to be stopped, which takes up the time for the treatment of the VOCs organic waste gas and reduces the speed of the treatment of the VOCs organic waste gas.
