Description

Technical Field

[0001] The utility model relates to the field technology of paint spraying waste gas treatment device, in particular to a paint spraying waste gas treatment device which is easy to transport and assemble. Background Art

[0002] When repainting is carried out in the paint room of an automobile factory, harmful gases including volatile organic compounds (dichloromethane, carbon tetrachloride, n-hexane, ethylene, trichloroethylene, ethanol, methyl mercaptan, methyl sulfide, formaldehyde, benzene, toluene, ethylbenzene, xylene, phenol, etc.) and paint mist can be produced. These harmful gases must be fully filtered and treated to meet emission standards before they can be discharged into the atmosphere.

[0003] Generally, enterprises have closed spray painting rooms with dedicated exhaust ducts. In order to prevent the waste gas generated by the product spray painting process from polluting the environment, the waste gas in the spray painting room is generally discharged into the atmosphere after passing through the waste gas treatment equipment;

[0004] However, the waste gas treatment equipment in the existing spray booths is assembled into a whole product after welding various parts, and then transported. After the customer receives the whole product, he will place it. This welding and assembly method has poor structural design, troublesome assembly, and inconvenient subsequent maintenance. The product transportation occupies a large space, is inconvenient for transportation, and has a high cost.

[0005] Secondly, the filter on this type of exhaust gas treatment equipment is composed of a frame, a protective net inside the frame, and an activated carbon filter body. The traditional filter frame is usually made as a whole and cannot be disassembled. After the filter has been used for a period of time, a large amount of dust and particles have accumulated on the activated carbon filter body that plays an adsorption role. The activated carbon filter body has basically lost its filtering function after a long period of weathering and erosion. At this time, the activated carbon filter body needs to be replaced. Since this type of filter cannot be disassembled, the frame, the activated carbon filter body and the protective net need to be discarded together, causing great waste.

[0006] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
