Description

A pulse bag filter

technical field

The invention relates to the technical field of bag dust collectors, in particular to a pulse bag dust collector.

Background technique

Due to the advanced dust removal technology and the greatly improved air-to-cloth ratio, the pulse bag filter has the characteristics of large air volume, small footprint, high purification efficiency, reliable operation, simple structure, and small maintenance. The dust removal efficiency can reach more than 99%;

The invention patent with the publication number CN108465306A discloses a bag-type dust collector, which is provided with a partition between the dust removal chamber and the ash hopper. After the dust-laden airflow enters the dust removal chamber, it will not affect the ash hopper, and will not cause "secondary dust" to the dust originally deposited in the ash hopper. It also reduces the height of the dust removal chamber, saving manufacturing costs and installation space. In addition, each tube is evenly opened with ventilation holes intuitively, so that the dusty air can enter the straight tube evenly, the filter bag can be fully utilized, and the dust removal effect is improved;

The structure of this invention still has deficiencies in the actual use process. Although secondary dust is avoided, the treatment of dust does not have cooling treatment. It is inconvenient to effectively recover and process flammable and explosive dust impurities. After a period of operation, the device needs to suspend dust intake for bag dust removal treatment, resulting in low dust removal efficiency.
