Classification of Dust Filter Bags According To Temperature and Materials

The dust removal bags of the bag type dust collector are classified according to the temperature and material:

1. Normal temperature cloth filter bag: the normal temperature cloth bag is mainly made of polyester, polypropylene, acrylic and other fibers through non-woven and textile processes. It has good air permeability, smooth surface, good dimensional stability, easy to peel off dust and other excellent properties. It is mainly used for dust removal and normal temperature flue gas treatment in industries with dust pollution in general industrial enterprises;

2. Medium temperature cloth filter bag: with the improvement of China’s attention to environmental protection, especially the rapid development of bag type dust removal technology industry in recent years, China has begun to use synthetic fiber to develop high-performance filter materials that can adapt to severe working conditions and have long service life. At present, the common medium temperature filter materials include aramid fiber and PPS series fiber, which are treated by dipping, waterproof, oil-proof and corrosion-proof processes, so as to achieve ideal results;

3. High temperature cloth filter bag: the high temperature cloth bag is mainly made of P84, expanded glass fiber, fine glass fiber and other high temperature resistant fibers through textile and non-woven processes. It has the characteristics of good thermal stability, high filtration efficiency and long service life. It is mainly used for dust removal under various high-temperature flue gas conditions.
