If the frame of the dust collector is the skeleton of the bag filter, then the dust bag is the heart of the bag filter. Many times people also call it a dust filter bag. ? The dust bag is a key part of the operation of the bag filter, usually cylindrical filter bag suspended vertically in the dust collector. A dust collector or a dust removal device is a device that separates dust from flue gas. The bag filter is also called a filter type dust collector and is a dry type high efficiency dust remover. It is a dust removal device that uses a bag filter element made of a fiber material to trap solid particles in a dust-containing gas. The principle of action is that the dust particles are intercepted by the collision of the fibers with the inertial force of the filter cloth fibers.
In pulse and air box type pulse dusters, dust is attached to the outer surface of the filter bag. When the dust gas passes through the dust collector, the dust is trapped on the outer surface of the filter bag, and the clean gas passes through the filter material into the filter bag interior. The cage inside the filter bag is used to support the filter bag to prevent the filter bag from collapsing, and it helps the removal and redistribution of the dust cake.
The fabric and design of the dust bag should strive for efficient filtration, easy removal of dust, and durability. The selection of dust bag is very important. It directly affects the dust removal effect of the dust collector. The dust bag is selected from the following aspects: gas temperature, humidity and chemical properties, particle size, dust concentration, filtration speed, clearance Dust and other factors.
