Dust bag refers to the bag in the bag filter, made of non-woven fabrics and woven fabrics. In the production process of thermal power generation, iron and steel, cement, chemical industry, etc., a large amount of dust and smoke will be generated, which will cause serious pollution to the atmosphere and human body. Therefore, the state sets strict requirements for the atmospheric emission of such enterprises. The bag dust removal is an ideal dust removal method widely used. The dust bag (dust filter bag) is called the heart of the bag filter, and plays a very important role in the dust removal effect.
The dust bag of the standard group can be operated continuously at a temperature of 204°C (instantaneous temperature 250°C) and can withstand the repeated fluctuation temperature of 250°C instantaneously, at the same time it has excellent dimensional stability performance, only less than 1 at a temperature of 250°C. % thermal shrinkage with excellent high temperature stability. Good chemical resistance will not affect the low concentration of acids and bases and most hydrocarbons. Even a small amount of fluoride will not significantly corrode it. High temperature dust bag filter material has been proven to be widely used in high temperature filtration, long-term use can maintain high strength and high wear resistance. Widely used in asphalt, cement, steel, non-ferrous metals, lime, dust, metallurgy, drying, broken stone, gypsum, plastic, carbon black, coke, shipbuilding, tobacco and other industries.
