Bag filter is introduced

Bag filter is a kind of dry dust filtering device. Filter material to use after a period of time, due to the screen, collision, stranding, diffusion, electrostatic effect, such as a layer of dust accumulation on the surface of filter bag, at the beginning of the dust layer is called layer, after the movement process, early become the main filter to filter material layer, depending on the role of the first layer, large mesh filter material can also get higher filtration efficiency. As in the accumulation of dust on the surface of the filter material, filter efficiency and resistance are corresponding increase, when the pressure difference on both sides of the filter material is very big, can put some tiny dust particles are attached to the filter material has been squeezed in the past, the dust collector efficiency decline. In addition, the resistance is too high will make the system of dust control of air volume dropped significantly. Therefore, filter resistance after reaching a certain value, the soot cleaning in time. Soot cleaning could not be broken when the first layer, in order to avoid efficiency decline.

The working principle of the bag filter

Filter separator is protecting air hole through filter layer, the dust particles in the air is filter layer intercept capture down, so as to realize the gas-solid separation device.

Filter type dust removal device including bag-type duster and granule layer dust remover, the former usually use organic or inorganic fiber fabric made of filter bag filter layer, while the latter is more than the filtration layer of the adoption of different size particles, such as quartz sand, river sand, ceramsite, slag, etc.

With powder repeat attached to the filter bag surface, the powder layer thickening and flow resistance value also increase; Pulse valve diaphragm issue instructions, around submerged pulse valve opens, the high pressure gas compressed air through the package, if there is no dust or small to certain degree, mechanical soot cleaning work will stop working.
