Usage of high temperature fiberglass filter bags

Glass fiber is a high-temperature filter material that is commonly used in industrial dust removal applications. The glass fiber filter bag is specially woven and surface treated to create an ideal filter material that can withstand high temperatures, medium temperatures, low temperatures, and high humidity. It is particularly useful in copper smelting flue gas purification processes where it operates at high temperatures of 200-300 ℃ and is exposed to corrosive acidic flue gas.

The woven fiberglass high temperature bag filter is made from alkali-free glass fiber 80N 8.2 yarn that has been interwoven after being immersed in a graphite-teflon treatment solution. The fabric structure is 5/2 weft satin weft double tube organization. The filter bag has specific conditions of use, including a temperature range of 200-300℃, filtration speed less than 1 m/min, operating pressure difference of 400-600mm water column, and back blow air pressure of 4-6 kg. The smoke composition is also a consideration, with the dust particle size being below 5 microns, population dust containing 100-500 mg/m3, 50: Content of 3-5%, 50: content of 0.1-0.5%, single sulfur content of 1000mg/m3, and fluorine content of 0.4-0.6mg/m3.

The technical index requirements of glass fiber high temperature filter bags include a service life of more than three months, filtration efficiency of >95% (with the population containing 10 dust), and the outlet dust content being less than 5 mg/m3 when the dust particle size is below 10 milligrams of rice. Glass fiber high temperature filter bags are commonly used in valuable dust purification, environmental recycling, and industrial dust removal applications.
