The filter bag for the pulse precipitator can be woven material or needle felt. Needle punched felt is usually thicker and more free fibers. Needle-punched felt is a kind of felt in which staple yarns are punched into looser plain weave fabrics in a needle-punched pattern, or these staple yarns are directly needled together to form unsupported felt. These fibers interlock to achieve the ability to intercept dust. People are accustomed to call this filter material a common filter material. Because of the large pore size between the fibers, it is difficult to intercept fine dust. In order to achieve better filtering effect, a continuous uniform multi-microporous and extremely smooth ePTFE film was pressed on its surface to form a membrane-coated filter material. Because of its extremely dense and smooth micropores on the surface of the film, the dust interception effect is very good, but also to solve the problem of ordinary filter material ash removal.
