Bag type dust collector is a dry dust filter device. Filter used for a period of time, due to the sieve, collision, detention, diffusion and electrostatic effect, bag table area accumulate a layer of dust, this layer of dust known as the first layer, after that, the beginning level is the main filtering layer, relying on the role of initial layer, larger mesh filter can obtain a higher filtration efficiency. With the accumulation of dust on the surface of filter material, the efficiency and resistance of the filter are increased. When the pressure difference between the two sides of the filter media is very big, some of them have been attached to the filter material. In addition, the resistance of the dust collector will make a significant drop in the air quantity of the dust removal system. Therefore, the resistance of the dust collector to reach a certain value, it is time to clear the dust. Ash can not destroy the initial layer, so as to avoid the efficiency decline.
工作原理 WORKING PRINCIPLE
Filter type dust collector is a equipment when smoke air hole containing dust through filter layer, air dust particles are intercepted by filter layer, so as to realize the gassolid separation .
Filter dust removal device comprises a bag type dust collector and granular layer dust removal, the former usually use organic fiber and inorganic fiber fabric made ofbag filter layer, filter layer and the latter with different diameter particles, such as quartz sand, river sand, ceramsite, slag, etc. With powder repeated attached to theouter surface of the bag, powder layer continuous thickening, bag type dust collector resistance value increases; pulse valve diaphragm issued a directive, aroundsubmerged pulse valve is open, compressed air of high pressure gas package get through , if there is no dust or it is small to a certain extent , mechanical cleaning work will stop .
