Fiberglass Needle—Punched Filter Felt Bag

　　Fiberglass Needle—Punched Filter Felt Bag

　　It has the advantages of high temperature resistance, corrosion resistance, dimensional stability, minimal elongation and shrinkage, high strength. And the tapetum fiber bears single fiber, three—dimensional micro—porous structure, high porosity and low resistance to gas filtration. It is a kind of high—speed and high— efficiency high—temperature filtering material. It is widely used in high temperature flue gas filtration of industrial kilns such as chemical industry, iron and steel, smelting, carbon black, power generation, cement, etc.

　　The filter bag is the key component to determine the dust removal efficiency and working temperature of the bag dust collector, and the cost of replacing the filter bag is the main maintenance cost of the bag dust collector. Therefore, the working life of the filter bag is related to the operation state and cost of the dust collector, so it is particularly important to select the appropriate filter material and design the reasonable structure.

　　The selection of filter material should be considered according to the temperature, humidity and chemical characteristics of the gas, the size, weight, shape, ponderability of particles, dust concentration, filtration speed, ash cleaning mode, emission concentration and the working system of bag dust collector. In general, the pulse spray bag filter uses needle felt, the chamber back blowing bag dust collector or the mechanical vibration bag filter selects the woven cloth.
