Technical Field
[0001] The utility model relates to the technical field of detection, in particular to a composite filter material air permeability detection device. Background Art
[0002] The filter bag is the heart of the bag filter during operation. Usually, the cylindrical pulse filter bag is vertically suspended in the dust collector. The dust-containing gas enters the dust collector from the air inlet, passes through the guide plate of the ash hopper, and some large dust particles in the gas are separated by inertia and fall directly into the ash hopper. The dust-containing gas enters the filter area of the filter bag of the box body. Most of the dust is captured on the outer surface of the filter bag, and the clean gas enters the filter bag through the filter material. The purified gas enters the upper box through the filter bag port and is discharged from the air outlet. The cage inside the filter bag is used to support the filter bag to prevent the filter bag from collapsing. At the same time, it helps to remove and redistribute the dust cake.
