Current Solving Method&Major Problem for Compressed Air Impurities
First, Filtration Processing method Compressed air will be initially treated by filtering particles and impurities, oil droplet, part of liquid water through filter. for traditional cartridge whose bottom is sealed, impurities will be gathered into internal filter. after penetrating into the bottom of filter chamber, impurities are drained out. Main problem Solid particles can not penetrated from the filter cartridge, it can be attached to inner wall of filter element, which will increase air resistance, at the same time penetrating water droplet and oil droplet may be taken away by compressed air again. Second, refrigeration Processing method Mainly use refrigerated dryer to cool the air, then decrease temperature of water content saturation from hot to cold. some water will be condensed into liquid water , and then drained out. Main problem The refrigerant evaporation temperature shouldn't be less than 2℃ due to the limit of refrigerated dryer's working...
