Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device used for coating preparation. Background Art

[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually a viscous liquid based on resin, oil or emulsion, with or without pigments, fillers, and corresponding additives, prepared with organic solvents or water. In the process of paint production, waste gas will be generated, so the waste gas needs to be treated. There are many ways to treat it, such as aeration, catalysts, activated carbon, purification towers, etc.

[0003] At present, most of the waste gas treatment devices used for paint preparation use activated carbon to treat the waste gas from paint production. The activated carbon is first filled inside the treatment box, and then the waste gas is transported to the purification box. The waste gas is treated by the adsorption effect of the activated carbon. However, in this process, the activated carbon filled and accumulated inside the purification box is prone to insufficient contact due to the excessively fast flow rate of the waste gas, resulting in low raw material utilization and inconvenience in achieving better treatment effects.

A connecting pipe 11 is fixedly connected to the top of the dust removal box 1, and the other end of the connecting pipe 11 is fixedly connected to the top of the purification box 2. By setting the spray heads 10, the sprayed water can be combined with the dust and water-soluble harmful substances in the exhaust gas for preliminary treatment. By setting multiple spray heads 10, the spray range can be increased to fully contact with the exhaust gas.

A filter screen 14 is inserted into the water tank 13. By setting the filter screen 14, impurities in the water can be filtered to prevent the sprinkler head 10 from being blocked when the water is recycled.
