Description

Two-stage smoke dust purifier

Technical Field

Background

During the cutting, welding and polishing operations on mechanical workpieces, a large amount of smoke is generated, and at the moment, a smoke purifier is usually installed in an operating room to filter out smoke particles contained in air. A smoke purifier generally includes a fan for generating a negative pressure suction force and a membrane-coated filter cartridge, and first sucks air containing smoke dust, passes the air through the membrane-coated filter cartridge, and then discharges the purified air from an exhaust port. When smoke dust passes through the film-coated filter cylinder, smoke dust particles are attached to the surface of the filter cylinder, so that the filtering and purification of the smoke dust are realized. Because the particle diameter of the smoke dust has large and small sizes, the film-coated filter cylinder has good filtering effect on the smoke dust with the particle diameter of 0.1-1 micron.
