Abstract
Description
Technical Field

[0002] Bag dust collectors have been widely used in fields such as industrial production and environmental governance. During the operation of a bag dust collector, the sealing of the connection between the air inlet and outlet ducts and the dust collector body is crucial. Traditional bag dust collectors generally use flange connections for the air inlet and outlet ducts. The sealing gaskets between the flanges age and become damaged due to long-term use, which can easily lead to gaps between the flanges, resulting in air leakage. Air leakage in the air inlet and outlet ducts will affect the air volume balance of the dust collector, making it impossible for the dust-laden gas to be fully filtered through the bags. At the same time, the filtered clean gas will be re-mixed with the untreated dust-laden gas, which will also reduce the overall dust removal effect.
