According to the dust bag filter bag filter bag filter selection method is the correct choice of filter cloth another important factor that must be considered, that is, different cleaning methods of bag filter cleaning ash energy, filtration Bag-shaped deformation of the different, should use different structures, varieties of filter cloth.
One-compartment anti-blowing cleaning method Branch-cleaning cleaning bag filter is the use of sub-chamber structure, the valve switch from room to room, forming a reverse air flow, forcing the bag shrinkage or bulging and cleaning. This cleaning method also belongs to the low kinetic energy cleaning, with the help of the working pressure of the bag filter as the cleaning power, repacking the airflow force in special occasions. Chamber bled cleaning dust bag filter requires the use of soft texture, easy deformation and stable size of the thin filter cloth, because the bag filter with the filter outside the filter points, so the choice of filter cloth slightly different .
Second vibration backflushing and cleaning with the way of cleaning the backflush cleaning and cleaning with the bag-type dust bag means both vibration and counter-flow double cleaning bag filter, the vibration of the dust loosening, the anti-air flow so that Dust off. Two ways to cooperate with each other, so that the cleaning effect can be improved, especially for fine particles of viscous dust filter. Such bags of dust filter cloth selection, in principle, with the sub-room cleaning bag cleaning dust the same way.
Three mechanical vibration cleaning method Mechanical vibration cleaning bag filter is the use of mechanical devices (including manual, electromagnetic vibration and pneumatic) so that the filter bag to produce vibration, vibration frequency from several times per second to hundreds of times. In addition to this type of bag filter mixers outside the small, mostly used within the filter round bag form. It is characterized by less kinetic energy applied to the dust layer and a greater number of actions, requiring the filter cloth thin and smooth, soft texture, is conducive to the transmission of vibration waves in order to form enough in all the filter surface vibration force.
