ENVIRONMENTALLY FRIENDLY WELDING FUME PURIFICATION DEVICE FOR ENVIRONMENTAL PROTECTION

摘要

Disclosed is an environmentally friendly welding fume purification device for environmental protection. The purification device comprises a positioning insertion ring (15), an activated carbon adsorption mesh (16), a photocatalysis plate (17), an air filter mesh (18), a tightening fixing plate (19), a clamping groove plate (191), a spring (20), a lamp tube power-on insertion sleeve (21), an ultraviolet lamp tube (22), and an insertion ring positioning support frame (23), wherein an air-gathering hood (3) is arranged at the top end of a settling box (4) in a supported and communicating manner, a purification box (2) is welded at the top end of the air-gathering hood (3) in a supported and communicating manner, and an axial flow fan (1) is arranged at the top end of the purification box (2) in a screw locking manner. Four bent supporting legs (8) are symmetrically supported and welded at the bottom of the left side wall and the right side wall of the settling box (4), two fire-retarding boxes (7) are respectively located between the left group of supporting legs (8) and the right group of supporting legs (8), and two rows of connecting support plates (13) are symmetrically welded between each fire-retarding box (7) and the two supporting legs on the left side and the right side of the fire-retarding box; the photocatalysis plate (17) is arranged, under triple filtering by the activated carbon adsorption mesh (16), the photocatalysis plate (17), and the air filter mesh (18), hazardous substances in welding fumes are almost completely decomposed and adsorbed, and therefore, the filtering effect of the device itself is effectively improved.
