HMC-type pulse jet bag warehouse roof precipitator 9 
 HMC-type pulse jet bag warehouse roof filter has a large gas processing capacity, good purification effect, convenient operation, maintenance of small, stable performance, reliable operation characteristics, and also has a small noise, long life filter bag, no mechanical moving wear. 
 Working principle: the air of dust into the dust box, the coarse particles of dust down the settlement rely on their own gravity and fall into the ash silo fine dust through a variety of effects are adsorbed on the dust of the bag by the dust collector at the bottom, with the the growth of time, the more the accumulation of thick dust collector resistance increased gradually declining amount of gas processed, in order to make the the precipitator often maintain an effective working condition, so that the pressure loss is kept within a certain range, you need to clear the adsorption of the bag wall outside of fouling. The cleaning process by the control device according to requirements issued a directive on electromagnetic pulse valve, so that the bag in an instant a sharp contraction to an expansion-contraction, dusty gas in the cleaning process, the pressure loss of the dust collector and processing is almost the same, this progressiveness one pulse bag filter. 
 Suitable arrangement in the top of the repository of a variety of powder, used to trap a variety of small and dry non-fibrous dust, is a simple library dust necessary equipment.
