Advantages of Air permeability of filter bags:
High surface efficiency:
- Usually industrial uncoated dust bag filter material, is to rely on the filter surface to establish a dust layer for effective filtration, establish an effective filtration dust layer for a long time, large resistance, low efficiency. The interception is not complete, the loss is also large, the bag chamber back blowing pressure is high, the dust is frequently cleaned, the energy consumption is high, and the service life is short, the equipment covers a large area.
- The PTFE membrane filter bags whether the dust is coarse and fine, all are trapped in the filter bag filter material surface, dust can not enter the filter material internal structure, that is, by the aperture of the membrane dust interception, no initial filtration period, from the beginning can be filtered, save filtration time and improve efficiency.
Low pressure, high flux continuous work:
- The traditional filter material for deep filtration, once put into use, dust penetration, the establishment of a dust layer, dust bag filter material permeability will be rapidly reduced. When filtering, the internal accumulation of dust can cause blockage, which increases the resistance of the bag collector.
- For PTFE membrane filter bags, dust cannot penetrate, so dust trapped on the outside of the filter bag. When the dust deposition in the thin film on the surface of the filter material reaches a certain thickness, it will automatically fall off. The filtering pressure keeps a very low level, air flow always stay at a higher level, make the dust catcher can work continuously.
Easy to ash:
- The operating pressure loss of any kind of filter material directly depends on the amount of dust left or retained on the surface of the filter material after cleaning. Traditional dust removal filter bag is easy to retain dust, so the dust removal time is long!
- The membrane coated filter bag only takes a few seconds, has a very good and superior ash cleaning characteristics, each ash can remove the dust layer, the filter material inside will not cause blockage, will not change the porosity and mass density, can maintain the low pressure loss work.
