Abstract
Description
Technical Field
[0001] This utility model relates to the field of bag filter technology, specifically to a jet cleaning device for reducing bag breakage in an electrostatic precipitator-bag filter composite dust collector. Background Technology
[0002] Currently, most baghouse dust collectors in China use either horizontal or vertical spraying for cleaning. The disadvantages of horizontal spraying are that it requires a large area and consumes a lot of air. Vertical spraying, on the other hand, requires a smaller area and consumes less air, but the airflow distribution in the vertical spraying chamber is uneven, resulting in a poorer cleaning effect.
[0003] A novel bag filter jet cleaning device (CN202122626241.5) uses a jet cleaning system where airflow from a storage tank is ejected through branch pipes and nozzles to clean the filter bags. The diameter of the branch pipes in the same group decreases sequentially along the airflow direction, ensuring equal flow rate and velocity from each nozzle. This results in uniform airflow acting on the same group of filter bags, improving cleaning efficiency and practicality. However, this device has shortcomings: poor jet cleaning effect, inadequate dust collection, and inconvenient filter bag replacement. Therefore, a jet cleaning device is needed to reduce filter bag damage in an electrostatic precipitator / bag filter composite dust collector to address these issues. Utility Model Content

Then, the gas storage... The tank 7 performs pulse jet spraying, and then diffuses the dust through the annular through-hole on the outer wall of the nozzle 8 to remove the dust. The dust then falls into the dust collection hopper 21 for collection. When dust needs to be treated, the dust collected in the dust collection hopper 21 can be transported to the dust storage silo through the configured dust conveying system for centralized treatment.
