Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a bag dust removal device. Background Art

[0002] Bag dust collector is a common industrial dust removal equipment used to remove particulate matter from the air to maintain a clean environment and air quality. The working principle is to introduce a mixture of air and particulate matter into the equipment, and then separate the particulate matter through the process of filtering the bag. Letting clean air flow out can efficiently remove fine particulate matter and has a high dust removal efficiency. In addition, it can adapt to different working conditions and particle properties and has strong adaptability.

[0003] However, when using a bag filter for dust removal, the smoke is generally passed directly into the dust collector. The smoke generally contains some large particles, and direct introduction will accelerate the clogging of the filter bag. Therefore, it is necessary to frequently inject high-pressure gas for cleaning, which reduces the service life of the filter bag. Utility Model Content
