The dust removal bag can be called the heart of a bag filter, commonly referred to as a dust removal bag or filter bag. The dust removal bag is a key part of the operation process of a bag filter, and usually a cylindrical filter bag is vertically suspended in the dust collector. The fabric and design of dust removal bags should strive for high-quality filtration, easy dust removal, and durability. The selection of dust removal bags is crucial as it directly affects the dust removal effect of the dust collector. The selection of dust removal bags should be based on the following factors: gas temperature, humidity and chemical properties, particle size, dust concentration, filtration wind speed, dust removal method, and so on.
A dust collector or dust removal equipment is a device that separates dust from the flue gas. And the bag filter, also known as the filter type dust collector, is a dry high-quality dust collector. It is a dust removal device that uses bag filter elements made of fiber fabric to capture solid particles in dusty gases. The principle of its action is that dust particles are intercepted due to the impact of inertial force with the fibers when passing through the filter cloth fibers. [1]
In pulse and air box pulse dust collectors, dust is attached to the outer surface of the filter bag. When dusty gas passes through the dust collector, the dust is trapped on the outer surface of the filter bag, while clean gas enters the interior of the filter bag through the filter material. The cage frame inside the filter bag is used to support the filter bag, prevent it from collapsing, and at the same time, it helps to remove and redistribute dust cakes.
