Description

Technical Field

[0001] The present application relates to the field of dust removal equipment, and in particular to a dust collecting device of a pulse bag dust collector. Background Art

[0002] Bag filter is a dry dust filtering device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter dust-containing gas. When the dust-containing 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. When the gas containing finer dust passes through the filter bag, the dust is retained, so that the gas is purified. After using the bag filter for a period of time, it is necessary to clean the dust in time. At present, the airflow is often used to reversely flush the filter bag to achieve the purpose of dust removal. However, the airflow pressure should not be too large during cleaning. Excessive pressure will damage the filter bag. Therefore, the airflow cleaning effect has certain limitations. For this reason, a dust collection device for a pulse bag filter is proposed.
