The selection of dust filter bags should be based on the temperature, humidity and chemical characteristics of the gas; the size, weight, shape, abrasiveness of the particles, as well as the dust concentration, filtration speed, cleaning method, emission concentration and bag dust collector Work system and other factors should be considered comprehensively. Generally, pulse injection bag dust collectors use needle felt dust filter bags, and chamber backflush bag dust collectors or mechanical vibration bag dust collectors use woven fabrics.

The dust removal filter bag has the advantages of glass fiber fabric with high temperature resistance, corrosion resistance, dimensional stability, minimal elongation and contraction, and high strength. The felt layer fiber supports single fibers, has a three-dimensional microporous structure, high porosity, and has low resistance to gas filtration. , is a relatively high-speed, high-temperature filter material.

Dust removal bags can be widely used for high-temperature flue gas filtration in various industrial rice kilns such as chemical industry, steel, smelting, carbon black, power generation, cement, etc.
