Jet plus bag filter is also named as pulsed-ejection bag filter that is one of bag filters. Bag filter is de-dusting equipment that adopts bag de-dusting technology (principle). Normally, bag de-dusting technology means filtering & de-dusting technology is realized with filter-bag. Material of filter-bag is natural fiber, chemical & synthetic fiber, glass fiber, metal wool or other fiber. Filtration fabric is made of above materials, which is stitched to filter-bag in various types, e.g. round-type and flat type etc. When filter-bag is used to filter and separate dust particle, the dust-contained gas can either go through filter-bag from exterior to interior, then dust can be separated on external surface of filter-bag, or the dust-contained gas can go through filter-bag from interior to exterior, then dust can be separated on inner surface of filter-bag. De-dusting process is fulfilled upon dust-contained gas is separated and filtered with filter-bag.
De-dusting process of bag filter is mainly fulfilled through filter-bag. Filtering mechanics is dependent of various filtering effects of filtering material and dust layer.
