[0003] For example, the utility model with patent number CN202021608622.X discloses a multi-stage purification device for exhaust gas in a spray paint booth, which has an air duct and a filter bag. The filter bag is an inner empty bag covered with filter material. The filter bag has at least two levels, and the filter bag of this level is in the filter bag of the next level. The first-level filter bag is connected to the air duct to introduce the exhaust gas of the spray paint booth for the first filtration and then enter the next-level filter bag for step-by-step filtration. The purified air is discharged from the last-level filter bag. The first-level filter bag is composed of a cage and filter material. The cage is connected and fixed to the air duct opening. The filter material is filter cotton, which is coated on the cage. The second-level and lower-level filter bags are box-type structures, and the roof and walls are supported by ribs.
