Description

Technical Field

[0001] The utility model belongs to the technical field of bag dust collectors, and particularly relates to a bag dust collector clamp for tail gas from solid waste incineration. Background Art

[0002] Waste incineration produces tail gas, which contains a lot of dust impurities. Bag dust collectors are often used for treatment. Bag dust collectors are a dry dust filtering device. They are suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt. The fiber fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the large particles and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.
