Technical Field

[0001] The present application relates to a field, in particular, to a waste gas treatment device for a raw material workshop. Background Art

[0002] The metal raw material workshop is a factory area dedicated to storing, handling and processing metal raw materials. The raw material workshop can store various types and specifications of metal raw materials, such as steel, aluminum, copper, etc. These raw materials may be stored in the form of plates, pipes, bars, etc., and are classified and organized according to type and specification. Since some welding and cutting operations are performed when metal is processed in the raw material workshop, the metal as a whole will produce certain waste gas.

[0003] Existing raw material workshops are generally equipped with waste gas treatment equipment to absorb metal waste gas and purify it. However, there is some dust mixed in the waste gas in the air environment of the raw material workshop. The waste gas will pass through the filter to filter out the dust before purification. However, after the filter has been used for a certain period of time, a certain amount of dust will adhere to its inside, which will have a certain impact on the efficiency of the waste gas entering the treatment equipment. In addition, the dust attached to the filter is time-consuming and labor-intensive to clean, which reduces the overall utilization efficiency of the waste gas treatment equipment.

[0004] In view of the above-mentioned related technologies, the inventor believes that the dust filter in the waste gas treatment equipment has the defect that dust is attached and is difficult to clean. Therefore, an waste gas treatment equipment for a raw material workshop is proposed to solve the above problem. Utility Model Content
