Through reasonable equipment selection and operation management, efficient purification of waste gas can be achieved, environmental protection requirements can be met, and the environment and human health can be protected.
[0003] The working principle of the bag filter is that when the dust-laden gas enters the bag filter, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. The gas containing finer dust passes through the filter bag, and the dust is retained on the outer surface of the filter bag, while the clean gas passes through the filter bag into the clean air chamber and is finally discharged from the air outlet.
