In the field of water treatment, \u0641\u0644\u062a\u0631 \u0643\u064a\u0633<\/strong> <\/a><\/span>has become a key equipment in the industrial, agricultural and municipal fields due to its high flow rate, low cost and high dirt-tolerant capacity. This article systematically analyzes the working principle, core advantages, selection strategy and industry applications of bag filter, and provides full-link solutions based on authoritative data and cases.<\/p>\n

I. What is a bag filter?<\/span><\/strong><\/h2>\n

Bag filter is a kind of physical filtration equipment that intercepts suspended particles in water through porous filter bag, and its core is composed of filter bag and shell. Filter bag materials include polyester (PE), polypropylene (PP), nylon (NMO) and polytetrafluoroethylene (PTFE), with a pore accuracy of 0.1 to 500 microns, which can be adapted to different particle retention needs. Compared with the traditional cartridge, bag filter unit area processing capacity increased by 5~10 times, and supports repeated cleaning and use, reducing the comprehensive cost by more than 30%.<\/p>\n

II.The working principle of bag filter<\/span><\/strong><\/h2>\n
    \n
  1. Physical retention mechanism: water enters the filter from the top or the side, and when it passes through the filter bag, the particles are blocked in the bag, and the clean liquid flows out from the outlet.<\/li>\n
  2. Multi-layer filtration design: the needle felt filter bag adopts a deep filtration structure, large particles are retained in the surface layer, and small particles are embedded in the fiber gap, which improves the dirt holding capacity.<\/li>\n
  3. Dynamic pressure resistance: Stainless steel support basket ensures that the filter bag does not collapse under high flow rate (up to 2400 gpm), avoiding the risk of bag bursting.<\/li>\n<\/ol>\n
