Welding fume purification scheme
In order to improve the welding work environment and prevent air pollution, it is necessary to collect the dust generated during the welding process, not to spread to the workshop:
Point to point: point to point is directly from the welding arc welding accessories include: large volume of flue gas out of the low pressure system, small volume and high pressure system of mobile welding fume purification system, on-site welding gas absorption after cleaning the direct discharge of mobile welding fume purification system, the purification effect is obvious, the use of low cost, flexibility strong, has the advantages of convenient operation etc..
Local ventilation: a fixed welding side or top of the working point set using exhaust hood, fan power, place the dust away, to achieve the purpose of improving the indoor environment, so the exhaust volume is greater than point to point, mainly for the local exhaust station is relatively fixed, and the welding point of a small range of mobile welding operation. This method saves air, the effect is good, save energy
Overall ventilation: most of the situation is moving station, the workpiece does not move, the changing point of dust production, can not use local exhaust hood to collect the smoke, then in order to make the workshop room to maintain a certain degree of cleanliness, need to use comprehensive ventilation measures, workshop ventilation frequency according to relevant regulations. In general the workshop on the height. Is considered to be the most dense smoke poly area, set the overall ventilation hood; also the side blowing smoke way, so as to form an air curtain above a certain height on the workshop, the flue gas lock up, and rushed to the exhaust hood, to remove flue gas. Compared with the overall ventilation, local ventilation by a large amount of exhaust effect is poor, high energy consumption, especially in the winter heating area, in order to increase the heat loss, need to consume a lot of energy, so the overall ventilation should be according to the specific After the analysis of the situation.
Filtration principle
The welding fume hood absorption through the suction arm into the filter unit, the first collision shunting plate, changing the direction of flow, the flow of gas flow, it can avoid the direct impact of the filter, has been circulating, dust particles were collected before filter cartridge separated fine particles after filtration cartridge filter with PTFE film separation of filtered clean air through the muffler into the outside world, complete the whole process of filtration. Dust particles separated from the filter cylinder with a PTFE film, the dust falls into the dust container under the action of the pulse back blowing.
Welding dust catcher, filter material with high precision PTFE membrane filter, this filter can ensure the cleaning effect of the cartridge and long service life, high performance filter barrel type filter to achieve the state of indoor 6mg emission standards, is a kind of new purification equipment. The utility model relates to a welding fume purifier, which is an environmental protection device for purifying the smoke and dust in the workshop.
Technical specification for welding dust remover
1) equipment shell bending processing, welding using CO2 gas shielded arc welding, welding intermittent internal, external continuous welding, testing according to the national standard; gas protection welding stability, welding heat deformation zone is small, the welding stress is small, no welding slag, no
The oxide skin, ensure dust body welding residual stress, welding quality, effectively prevent the equipment used in the process due to the stress caused by the release of body deformation and cracking, improve equipment reliability, ensure the tightness of welding.
2) before the equipment inside and outside surface grinding smooth, spray treatment.
3) the filter material is made of flame retardant paper material, which has excellent filtering performance and is easy to clean.
Product features:
1, electronic pulse rotating back blowing device, all directions, no dead corner ash removal, dust removal effect is good, extend the filter life.
2, the filter tube coated polyester fiber filter material, so that the filter cartridge long life, more thorough cleaning, increase the filter area, improve ventilation efficiency.
3, the use of laser cutting material production product incision smooth, in order to ensure the sealing of the equipment, through the design of noise reduction makes the noise to a minimum.
4, equipped with a flexible arm, to absorb all kinds of smoke and dust, the flexible arm can rotate 360 degrees hovering at any position, can be moved to the mouth of the dust hood you need, to absorb the pollution from the source, to avoid the pollutants to diffuse and improve the indoor environment.
5, drawer type recycling material box design, convenient for daily maintenance, and material recycling.
Electric welding machine welding smoke purifier principle: smoke exhaust fan by negative pressure suction duct through the exhaust suction cleaner (filter) inside the box body by gravity settling chamber, and the upward airflow, coarse dust landed at the bottom of dust collector, dust particles coated by the filter trapping on the outer surface, clean gas after decomposing and purifying multi filter after being discharged from the air outlet
