Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a VOC waste gas emission filter. Background Art

[0002] VOC is the abbreviation of volatile organic compounds, which is a general term for volatile organic compounds. Many manufacturing companies today produce VOC waste gas, such as ink from printing plants, waste gas from paint spraying rooms, waste gas from rubber factories, or waste gas from pharmaceutical factories, etc., which have a huge impact on human health. The current methods of purifying VOC waste gas mainly include combustion, catalytic incineration, activated carbon adsorption, wet scrubbing, condensation, photooxidation and biological treatment.

[0003] When treating VOC waste gas, an alkaline solution is usually used to pass the gas into the alkaline solution to neutralize the waste gas. However, when treating the waste gas, a large amount of impurities are easily accumulated inside the alkaline solution, which makes it inconvenient for subsequent staff to clean up the impurities inside the alkaline solution. For this reason, we have proposed a VOC waste gas emission filter. Utility Model Content
