Introduction This product works using physical filtration, clean and efficient, easy to maintain, clean rate can reach more than 96%, reaching environmental acceptance criteria. Easy to use cleaner for mechanical processing, automobile assembly plants, maintenance of welding fume purification plants and other operations. Inhalation of welding fumes, purified directly discharged in the room can help maintain a closed room in winter kept at room temperature, easy operation. Monomer purification using movable type structure, use of the environment more adaptable. Worm fan with a high-performance, suction volume, low noise, excellent absorption stability. II. Welding smoke purifier role Sunyata environmental welding fume purifier is a purification device designed for industrial welding fumes and light particles and design, it is lightweight and flexible, easy to operate, it is also widely used in chemical, electronics, metal processing, tobacco, glass, pharmaceuticals, food processing, clean rooms, hospitals and other industries and other dust, smoke contaminated sites. III. Mechanism of welding fume dedusting exhaust gases are sucked fan vacuum cleaner, large particles of airborne dust and micro-level smoke exhaust filter into the high efficiency filter barrel. Clean air filtered by the fan discharge at the bottom of the device. IV. Application areas Arc welding, CO2 arc welding, MAG welding, special welding, gas cutting and other flue gas melt steel, stainless steel, aluminum and other metals produced during welding process. Welding fume, also known as welding fumes, refers to welding operations often produce some toxic substances. Such as: acetaldehyde, rosin acids, isocyanates, nitrogen oxides, sulfides, hydrocarbons. And flying in the air. Welding fume is a very complex matter, the elements have been found in smoke as many as 20 kinds, of which the most abundant is Fe, Ca, Na, etc., followed by Si, Al, Mn, Ti, Cu, etc. The main welding fume harmful substances as Fe2O3, SiO2, MnO, HF, etc., wherein the content of most of Fe2O3, generally accounting for 35.56 percent of total dust, followed by SiO2, in an amount of 10 ~ 20%, MnO accounts for 5 to 20 about%. Metal welding, laser cutting, when the grinding operation, a lot of dust suspended in the workshop, to be inhaled will seriously affect the health of the lungs, resulting in chronic manganese poisoning, welders pneumoconiosis and other serious diseases. Therefore, you must enter these harmful welding fume purification treatment prior to welding fumes breathing zone. Welding fume control technology: types of pollution generated by the welding process more harm large, will lead to a variety of occupational diseases (such as welders silicosis, manganese poisoning, electric ophthalmia, etc.) occurred, it has become a major environmental hazard. With deep research, governance technologies are maturing, welding pollution has been relatively effective control. Welding process serious pollution to the environment and cause great harm to the welder, for dust control, should be sources of pollution, management approach and personal protection three aspects.
