Industrial vacuum cleaners
mainly separate solids and air through filter media. Common industrial vacuum cleaners on the market generally have one or two filtrations. For example, the wet and dry type is a single-weight filter with a filter material, and the dry-type industrial vacuum cleaner uses a filter. Double filtration system with filter bag. The general filtration accuracy of the filter element is about 10 microns. The precision can be less than 1 micron by coating or using special materials. The filter fabric often uses non-woven fabric or polyester needle felt. The process keeps the accuracy around 0.5 microns.
At present, some companies have improved the filtration accuracy and greatly improved the air purification through the transformation and increase of the number of filter media. Currently, more than two filtration methods are commonly used, three-stage filtration is used for dry powder, and wet and dry type are used. Adopting double filtering, the special vacuum cleaner for welding fume adopts the quadruple filtering method. Through the modification and upgrade of the filtering medium, such as the use of high-efficiency filter (HEPA), the use of industrial vacuum cleaners can be expanded and the use effect can be improved.
working principle The industrial vacuum cleaner
evacuates the inside of the barrel through multi-stage high-pressure fans, vortex fans, vortex air pumps and other equipment, so that its negative pressure quickly rises. The high negative pressure causes air to quickly flow into the barrel through the air inlet, and the barrel passes the suction brush. And the suction pipe, the flowing air carries the solid particles that need to be collected and processed into the barrel, the filter bag is connected to the air inlet, the solid is attached to the inner surface of the filter bag, the initially filtered air passes through the gap of the filter bag, and then passes through The secondary filtration of the filter element can make the air meet the discharge standard. The filtered air enters the exhaust duct through the exhaust port of the fan or air pump and is finally discharged back to the interior of the workshop to reduce energy, especially heat loss.
The higher the negative pressure, the stronger the suction, and the wider the diameter of the suction port, the flow rate will increase, and the corresponding negative pressure will become smaller, and the suction will become smaller. By selecting a suitable model, the negative pressure can be kept within a constant range. To adapt to the extraction and processing of different materials.
