Welding soot purifier

Abstract

The invention discloses a welding soot purifier. The welding soot purifier comprises a housing, an air inlet, an air outlet and a PLC control device which is arranged in the housing. A laminating filter cartridge and a negative in dedusting device are successively arranged along the flowing direction of gas, an induced draft fan is further arranged on an air flow channel, and the negative ion dedusting device and the induced draft fan are electrically connected to the PLC control device; welding soot can filter relatively large particles through the laminating filter cartridge and is ionized through the negative ion dedusting device and generates a lot of negative ions, so that the purifying effect is good and the purifying rate reaches 98% above, and the soot needs not to be discharged outward and can be directly used as an internal cycle of air in a working site, and meanwhile, the generated negative ions are conveyed to air to remove dust, sterilize and remove smells, so that the air quality of the working site is greatly improved; moreover, the purifier is precise in structure and small in noise, and is particularly suitable for working places generating flue gas, for example, handle welding, electric-arc welding, carbon-dioxide arc welding, MAG welding, carbon arc air gouging, gas fusion cutting, special welding and the like.

Description

technical field [0001] The invention belongs to the technical field of air purification and preparation, and relates to a welding fume purifier suitable for workplaces where fumes and dust are generated in processes such as welding, cutting and grinding, and is especially suitable for handle welding, arc welding, carbon dioxide shielded welding, MAG (melting electrode active gas shielded arc) welding, carbon arc gouging welding, gas fusion cutting, special welding and other workplaces that generate smoke. Background technique [0002] Workplaces such as cutting, grinding, polishing and welding will produce harmful gas and dust, especially welding, which will produce a large amount of harmful gas and dust, and the main harmful substance in welding fume is Fe 2 o 3 , SiO 2 , MnO, HF, etc., among which Fe is the most 2 o 3 , the main components of toxic and harmful gases in welding fume are CO, CO 2 , O 3 , NO X 、CH 4 Among them, CO accounts for the largest proportion, ...

AI Technical Summary

Problems solved by technology

[0004] The current welding fume purification equipment mainly includes filter cartridge dust removal, bag filter and oil fume purifier, etc., which can only solve the filtration of large oil mist and particles, and the purification efficiency is low; the electrostatic adsorption method is a physical and chemical method. Positive and negative ions are attached to the mist, welding smoke and exhaust gas particles or molecular clusters, so that the oil mist, welding smoke exhaust gas particles or molecular clusters are collected by the electrostatic field plate to realize the purification of oil mist exhaust gas, but the purification efficiency is reduced because the exhaust gas molecules cannot be cracked and It cannot remove peculiar smell; in addition, due to the low purification efficiency, the purified gas can only be discharged outside, and cannot be used for internal circulation of air in the workplace
