The filter bag has excellent drawing performance stability and heat resistance in the process of use. When used, the filter bag is mainly used to represent the highest performance in the filter material industry, and is also the most high-end product in all commonly used filter materials. The filtration efficiency and filtration accuracy have reached a high level.
The filter bag has a certain amount of chemical stability and heat resistance when used. The filter bag is a key part of the operation of the bag filter, and the cylindrical filter bag is usually suspended vertically in the dust collector. The fabric and design of the filter bag should strive for efficient filtration, easy removal of dust, and durability.
In the pulse and air box type pulse dust collector, the dust is mainly attached to the outer surface of the filter bag. When the dust gas passes through the dust collector, the dust will be trapped outside the filter bag. Through its 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 in the filter bag is filtered by the thickness of the entire filter layer, and is deep-seated when used. The depth direction of the entire filter layer is directly formed by the fiber to form a three-dimensional porous structure, from inside to outside, from loose to dense, Gradient filtration, high volumetric capacity, long filtration life, low pressure drop.
The filter bag is mainly composed of a screen cover, a filter layer, a main filter layer and the like during the manufacturing process. The filter bag is designed to effectively absorb the oil in the liquid when used, and the porosity in the filter material can be as high as possible. 80% greatly improves the service life of the product. Oil up to 12 to 20 times the weight of the bag itself.
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.
