The dust filter bag is a key part of the bag filter. Generally, cylindrical filter bags are hung vertically in the dust collector.
Dust collector is equipment that separates dust from flue gas. The bag filter is also called filter dust collector. It is a dry high-efficiency dust collector. It is a dust removal device that uses bag filter elements made of fiber woven materials to trap solid particles in dust-containing gas. The principle of action is that dust particles are intercepted by collision with the fibers due to inertial force when they wind around the fiber of the filter cloth.
In the pulse and air box pulse dust collector, the dust adheres to the outer surface of the filter bag. When the dust-containing gas passes through the dust collector, the dust is trapped on the outer surface of the filter bag, and the clean gas enters the filter bag through the filter material. The cage inside the filter bag is used to support the filter bag and prevent the filter bag from collapsing. At the same time, it helps to remove and redistribute the dust cake.
The fabric and design of dust removal cloth bags should pursue high-efficiency filtration, easy dust stripping and durable effects. The selection of the dust filter bag is very important, it directly affects the dust removal effect of the dust collector. The selection of dust filter bag should be selected from the following aspects: gas temperature, humidity and chemistry, particle size, dust concentration, filter wind speed, dust cleaning method and other factors.
