Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to waste gas treatment equipment for water-based paint production. Background Art

[0002] Any paint that uses water as a solvent or dispersion medium can be called a water-based paint. Water-based paints include water-soluble paints, water-dilutable paints, and water-dispersible paints (latex paints). In the production process of water-based paints, waste gas treatment equipment is required to purify the waste gas generated in the workshop.

[0003] During use, the existing water-based paint production waste gas treatment equipment uses a fan to draw the gas in the workshop into a treatment box, which is filtered through a filter and then sprayed with a liquid medicine to treat the waste gas. At the same time, in order to avoid clogging of the filter, a cleaning mechanism is usually equipped. When the cleaning mechanism cleans the filter, it is unable to collect the dust cleaned by the device, which causes the dust to diffuse in the treatment box and adhere to the filter after cleaning, resulting in poor cleaning effect, which affects the use effect of the device. Therefore, water-based paint production waste gas treatment equipment is urgently needed to solve the above problems. Utility Model Content
