Description

Technical Field

[0001] The utility model relates to the technical field of bag filters, in particular to a stainless steel bag filter. Background Art

[0002] Bag filter is a common industrial filtration equipment used to remove solid particles or suspended matter from fluids. The bag can be made of fiber material or other filter materials. The working principle is to pass the fluid to be filtered through the bag filter, the solid particles are filtered out, and the clean fluid flows out through the pores of the bag. Bag filters are widely used in chemical, food processing, pharmaceutical, automotive, electronics and other fields to treat solid particles in wastewater, waste gas, liquid processing, as well as dust and pollutants in the air.
