What is the effect of a good brand of Linyi smoke purifier
Control measures of welding fume
Welding fume, also known as electric welding fume, is a kind of toxic substance which is often produced in welding operation. Such as: acetaldehyde, rosin acid, isocyanate, nitrogen oxides, sulfides, hydrocarbons, etc.. Welding fume is a very complex material, LANs has been found in the smoke of up to more than 20 kinds of elements, of which the most content is Fe, Ca, Na, followed by Si, Al, Mn, Ti, Cu, etc.. The main harmful substances in welding fume are Fe2O3, SiO2, MnO, HF and so on, the content of which is Fe2O3, which accounts for 35.56% of the total amount of smoke and dust, followed by SiO2, the content of which accounts for about 10 ~, MnO accounts for about 5 ~ 20%.
The welding fume treatment technology: the types of pollution produced in the welding process, the harm is great, will lead to a variety of occupation disease (such as silicosis, [1] welder manganese poisoning, electric ophthalmia etc.) occurred, has become a major environmental pollution. With the deep research of the relevant research and the improvement of the technology, the welding pollution has been controlled effectively. The welding process of the pollution is serious, cause great harm to the environment and the welder for smoke management, from 3 aspects of pollution sources, governance and personal protection to.
There are many aspects of the treatment of welding fume, which mainly has three aspects:
1, technical aspects
1, the use of no smoke and smoke less welding process
2) the development and use of low dust and low toxicity welding materials
3) improve the welding mechanization and automation
2, to take effective measures of ventilation and smoke purification
3, personal protection
To prevent the welding smoke harm to operators, prevent the flue gas directly inhaled into the lungs, a welder should wear masks, special welding station or in sealed places should also wear a gas mask. The workshop is equipped with welding auxiliary device occasions, to have the sense of self-protection, as far as possible the use of automatic welding process and mechanical equipment to complete the welding work, so that the operator away from the smoke area.
Hazard of welding production
With the continuous expansion of the scale of welding production, a large number of welding material consumption, labor hygiene and environmental protection of welding production is also on the agenda. In the past, our country has not paid enough attention to the environmental protection and sanitary problems of welding. Therefore, it is imperative to make the welding process from dirty, boring and dangerous work into green environmental protection.
SYD series electric welding machine welding fume purifier, welding fume dust remover product features:
1, the use of movable universal vacuum tube, can be up and down, around the location of the dust, from the source to effectively remove dust.
2, the integration of high efficiency polyester film coated filter element, sub micron dust filter, dust, dust (0.3-0.5 m) filtering efficiency of more than 99.5%, high filtration efficiency, long service life.
3, according to the nature of smoke and dust to choose the appropriate filter media, to meet the different nature of the dust purification treatment. Such as the chemical properties of the dust activated carbon filter, anti-static requirements of the use of electrostatic adsorption filtration.
