Monofilament filter cloth and accessories selection

 Polyester based monofilament filter cloth filter cloth cleaning method used baghouse filter cloth cleaning method is the right choice another important factor that must be considered , that different ways of cleaning due to cleaning baghouse energy bag deformation characteristics, the structure should use different varieties of cloth .

     A sub-room cleaning type cleaning method sub-room cleaning type bag filter cleaning method is the use of sub- chamber structure , the valve chamber by switching the formation of reverse flow , forcing bag shrink or swell while cleaning . This cleaning method is also a low- momentum -type cleaning , by means of pressure of work as a baghouse cleaning power , only on special occasions reprovision blowback airflow power . Sub-room cleaning type bag filter requires cleaning methods use soft, easily deformed and dimensionally stable thin cloth , because of the baghouse filter with inner and outer filter of the points , so a slight difference in the selection of filter cloth .
    Two vibration -type cleaning method with Blowback Blowback vibration and with style baghouse cleaning method is both vibration and reverse flow dual role baghouse cleaning , the vibration loosening the dust cake , reverse airflow so dust off . With each other in two ways , so that the cleaning effect can be improved, especially suitable for fine particles of sticky dust filtration . Such dust bag monofilament polyester fabric selection, broadly in line with sub-room cleaning type bag filter cleaning the same way .
    Three mechanical vibration mode mechanical vibration cleaning bag filter cleaning method is the use of mechanical devices ( including manual , electromagnetic vibration and pneumatic ) of the bag to vibrate , the vibration frequencies from a few to hundreds of times per second . In addition to these small baghouse mixture mixing machines, mostly using the form inside the filter bags circle . Its characteristics are applied to the kinetic energy of less dust layer which acts more frequently , requiring cloth thin and smooth , soft texture , is conducive to transfer vibration wave in order to form a sufficient total filter surface rapping force .
    How to choose dust accessories ?
    The first is dustproof, non-powered dust . Such as loading and unloading , transport belt when you add a chute , you can greatly reduce the amount of dust, soot handling ; handling bulk material should be used locally confined, that the resulting dust, soot cycle in which the kinetic energy it consumes , the dust basically natural settling down. This mechanical dust dust accessories in a foreign country is called non-powered dust, in most places are suitable for non-powered dust ; Or first pretreated using unpowered dust , prevention is always better than treatment cost-effective.
    The second is the secondary use of spray , or foam dust . Spray directly on the one hand the flue gas temperature is relatively high , the direct evaporative spray cooling can be used to achieve a small amount of water to cool the flue gas , the volume shrinkage , speed reduction is also beneficial to remove dust. Other hand, can make the dust particles after wetting , mutual bonding , cohesion, grew up in the atmosphere and it is easy to separate ; Therefore, from conservation, and energy cost reduction point of view, we must first consider the non-powered dust and direct spray dust .
