When the filter bag is in use, it is a key part of the operation of the bag filter, and usually a cylindrical filter bag is vertically suspended in the filter. The fabric and design of the filter bag should strive for efficient filtration, easy removal of dust, and durability.
In the bag-type pulse dust collector and pulse filter bag, the dust is attached to the outer surface of the filter bag. When the dust gas passes through the dust collector during use, the dust will be trapped in the filter bag. The outer surface, and clean gas through the filter into the filter bag inside. The cage inside the filter bag is used to support the filter bag to prevent the filter bag from collapsing, and it helps to remove and redistribute the dust cake.
The filter cloth of the filter bag is filtered by the thickness of the whole filter layer. When it is used, it belongs to deep filtration. The depth of the entire filter layer is formed by fibers to form a three-dimensional loose porous structure, from inside to outside from loose to dense, forming a gradient filter. High dirt capacity, long filtration life, low pressure drop.
Filter bag processing materials are PP (polypropylene), PE (polyester), PTFE (polytetrafluoroethylene), from the pre-filter layer, the main filter layer and screen cover three parts. It is designed to effectively absorb grease from liquids. The porosity of the filter material is as high as 80%, which greatly increases the service life of the product. The amount of oil absorbed is up to 12~20 times the weight of the filter bag itself (depending on the fluid and grease characteristics and flow rate).
The filter bag is hot melt-blown with pure polypropylene capillary fibers. The outer layer is a thick layer of deep-filtering material to provide layered filtration, and a large-diameter filter element is included to further enhance the overall deep-layer filtration effect and improve the ability to contain impurities. The average service life is more than five times that of ordinary polypropylene filter bags. The highest filtering accuracy is 3um. The collar is a plastic ring.
