How to deal with welding fumes?

After the fume and exhaust gas generated by welding is captured and collected by the Flexible Suction Arm, it enters the high-efficiency filter cartridge Dust Collector through the main pipe with a gradual diameter type (the purpose is to balance the wind speed and air volume at the end of the pipeline). The inside is blocked and purified by the high-efficiency purification filter. Part of the large particle dust falls into the ash hopper at the lower part of the dust collector due to the action of gravity, and the other part of the small particle dust adheres to the outside of the filter element under the action of the negative pressure of the fan. The pulse valve is under the control of the controller. , At regular intervals, the filter parts of the system are automatically backflushed from the inside to the outside to clean the dust. During the backflushing process, the small particles of dust fall into the ash hopper for collection. After a certain amount of dust is accumulated in the ash hopper, it needs to be transported out for processing. The clean gas passes through the filter element, enters the exhaust port, and is discharged into the atmosphere from the chimney at a high altitude under the action of the centrifugal fan.

Capture and collection device
The arm is light and flexible, can be stretched arbitrarily, hovered arbitrarily, 360 degrees of free rotation, accurate positioning without offset. The hood is available in the form of a cast iron top hat or a horseshoe flare. Its good stretching and hovering characteristics can not only be used with various types of welding fume purifiers and dust collectors, but also can be directly installed on walls or systems with pipelines for fume and gas emission. The hood is made of high temperature, corrosion resistant and anti-aging materials. The inner wall and bracket are made of stainless steel, which will never rust. Corrosion resistance, acid and alkali resistance, high temperature resistance, light weight, high strength, with power assist device, and labor-saving operation. , Hover freely. The suction arm is widely used in metal processing, welding fume, workpiece grinding, thermal processing oil mist treatment, odor removal, dust removal and other industries.

The filter element used in the welding fume collection and treatment system is a polytetrafluoroethylene (PTFE)-coated polyester filter material. This filter material is a high-tech product. Its microporous structure can be obtained by mechanical stretching under special conditions. It has not changed its original characteristics at all. The pore size of the microporous filtration membrane can be controlled at 0.2-0.3 μm, and the filtration method belongs to the membrane surface filtration. The surface of the membrane is smooth and has excellent chemical stability, corrosion resistance, acid and alkali resistance, no aging and hydrophobicity. The dust trapped on the membrane surface is easily peeled off during filtration, and its ventilation rate can be maintained at the same level for a long time. Since the film-coated filter material uses its smooth and non-stick surface to retain dust, this feature can not only save the compressed air volume of the pulse cleaning system, but also avoid the wear of the film base cloth by the smoke and dust, prolonging the use of the filter cartridge. longevity while providing the lowest and smoothest pressure drop across the equipment. The film-coated filter cartridge has a large area and a small volume, which reduces energy loss, increases its flow rate, and prolongs maintenance-free time. The high-efficiency film-coated polyester filter cartridge is the best choice for welding fume collection systems.
