A dust collector or dust collector equipment is a device that separates dust from flue gas. A bag dust collector, also known as a filter dust collector, is a type of dry dust collector that uses woven fabric bag filter elements to capture solid particles in dusty gas. Its working principle is that dust particles are intercepted by colliding with the fibers as they pass through the filter fabric due to the effect of inertial force.

In pulse and box-type pulse dust collectors, dust adheres to the outer surface of the filter bags. As the dust-laden gas passes through the collector, the dust is captured on the outer surface of the filter bags, while the clean gas passes through the filter material into the interior of the bags. The cage inside the filter bags supports them to prevent collapse, and it also aids in the removal and redistribution of the dust cake.

The fabric and design of dust collector bags should strive for effective filtration, easy dust shedding, and durability. The selection of dust collector bags is crucial, as it directly affects the dust removal efficiency of the dust collector. When choosing dust collector bags, consider factors such as gas temperature, humidity, chemical properties, particle size, dust concentration, filtration air velocity, and dust cleaning methods.
