Welding fume purification processing technology flywheel and gear surface, so a large amount of welding fume will be formed during the electric welding operation. The welding fume is generally separated by gas-solid two-phase flow to carry out purification. The methods to separate the gas-solid two-phase flow specifically include mechanical equipment foundation settlement dust removal, wet test dust removal, pure-air laser fume extractor and electrostatic adsorption dust removal. The foundation settlement dust removal and wet test dust removal of mechanical equipment can purify fine particles with a particle size of more than 10um and 5um respectively. Both foot filter dust removal and electrostatic adsorption dust removal can purify fine particles above 0.1um in size.

The particle size of welding fume is between 0.1um-5um, so both the foot-operated filter dust removal and electrostatic adsorption dust removal can meet the purification requirements. The area in the workshop is narrow, and there is no indoor space for the purifier. A steel structure platform must be built on the safe passage of freight, and the purifier must be assembled on the network platform. Because electrostatic adsorption dust removal must clean up the electrostatic induction activated carbon fiber every month, the maintenance amount is relatively large, so the machine pure-air co2 hepa carbon filter for laser cutter is used to collect the smoke and dust for purification.

Welding fume is rich in harmful particles, and immediate contact with the filter cartridge will cause the filter cartridge to be blocked quickly, which cannot be eliminated by single pulse ash removal. Therefore, a pre-painting equipment is upgraded in the dust removal system software. The pre-painting equipment sprays the light calcium powder evenly to form a powder layer on the surface of the filter cylinder. The dust adheres to the powder layer produced by the light calcium powder, which is very easy to be single pulsed. The removal of the ash removal system software can reasonably increase the service life of the smoke filter cartridge type.
