Description

Technical Field

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

[0002] As people's desire for improving the environment increases, the environmental pressure faced by enterprises is becoming increasingly severe. In the field of chemical production technology, a large amount of industrial waste gas is generally generated in the production workshop. This waste gas comes from the volatilization of raw materials, semi-finished products and finished products. If the waste gas is directly discharged to the outdoors, it may cause serious pollution to the atmosphere.

[0003] When treating exhaust gas, a filter should be used to filter out impurities and dust in the exhaust gas. After long-term use, impurities and dust accumulate on the filter surface, causing clogging of the filter mesh. The existing treatment method is usually to clean it after disassembly, which has a lag, affecting the filtration efficiency before disassembly and increasing the workload of operators. In addition, the existing exhaust gas often contains toxic substances and odors, and the existing devices are unable to deal with these toxic substances and odors, reducing the applicability of the device. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content
