Dust removal bag, dust collector bag, dust removal filter bag. The heart of a bag type dust collector during operation is usually a cylindrical pulse
Product details
PPSThe filter bag is the heart of the bag filter during operation. Typically, a cylindrical pulse filter bag is suspended vertically in the dust collector. The dusty gas enters the dust collector through the air inlet and passes through the guide plate of the ash hopper, causing some large particles of dust in the gas to be separated by inertial force and directly fall into the ash hopper The dusty gas enters the filter bag filtration area of the box, and the vast majority of the dust is trapped on the outer surface of the filter bag. The clean gas enters the inside of the filter bag through the filter material, and the purified gas enters the upper box through the filter bag mouth before being discharged through the air outlet The cage inside the filter bag is used to support the filter bag, prevent it from collapsing, and at the same time, it helps to redistribute the dust cake.
