CNMC countercurrent pulse cleaning bag type dust collector is the introduction of foreign new equipment, new technology, improved digestion by a new high-efficiency pulse jet bag filter. It has a handle large amount of wind, high purification efficiency, small footprint, small bag wear, long service life, replace the bag is simple, easy maintenance. Cleaning by pulse cleaning dust countercurrent, its electrical control sequence controller, reliable performance. Features: 1, the device uses pulse cleaning dust way, is the best kind of current cleaning effect on the device casing is divided into eighteen each other through a small chamber, and with a long venturi tube connected, use programmable pulse to achieve the purpose of cleaning, in the structure canceled the injection tube and the upper end of the small bag venturi, simple structure, easy operation and maintenance. 2, compared with other domestic dust, the device has a handle large amount of wind resistance characteristics of small systems, a wide range. (Room temperature, high temperature and dust concentration <60g / m3 mixed gas purification and recovery process) 3, the partition on the flower box board edge pressed into a certain tapered hole, brought into contact with the smooth surface of the bag forming, sealing, and reduce the hole edge with dust bag wear. 4, simple and reasonable structure, small footprint, can be installed indoors and outdoors. Users can according to their production process, the process air volume, choice of models or a combination of parallel and provide carbon steel or stainless steel filter as needed.
