Basic introduction: baghouse is a dry dust device. After the media for some time, due to sieving, collision, retention, diffusion, electrostatic and other effects, the bag surface layer of accumulated dust, this layer is called the primary layer of dust in the subsequent course of the campaign, became the primary layer filter the main filter layer, relying on the role of the primary layer, the larger mesh filter can be obtained a high filtration efficiency. With dust accumulated in the filter surface, filter efficiency and resistance increases correspondingly, when the pressure differential across the filter is large, will some tiny dust particles adhering on the filter in the squeeze past, precipitator efficiency. In addition, the resistance is too high dust significantly decreased the amount of wind dust removal system. Therefore, dust resistance reaches a certain value, to timely cleaning. When cleaning the primary layer can not be destroyed, so as not to decrease the efficiency. Baghouse structure is dominated by the upper part of the box, the middle box, lower box (hopper), cleaning systems and ash bodies and other components. Baghouse performance is good or bad, in addition to the correct choice of materials outside the bag, bag filter cleaning system plays a decisive role. To this end, the cleaning method is one of the distinguishing characteristics of baghouse, it is important also baghouse running ring.
