Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a pulse dust collector which is easy to clean. Background Art

[0002] Pulse dust collectors are widely used in various industrial fields, such as steel metallurgy, cement manufacturing, chemical industry, food and medicine, to deal with dust pollution. The core components of pulse dust collectors include filter bags and injection systems. When working, dust-laden gas enters the dust collector through the air inlet, and is filtered by the filter bag. The dust is retained on the outer surface of the filter bag, and the purified gas is discharged through the air outlet. When the dust accumulates to a certain extent, the injection system automatically triggers the cleaning program, and sprays compressed air to the filter bag through the nozzle, generating a strong airflow, vibrating the dust on the surface of the filter bag and causing it to fall into the ash hopper;

[0003] For example, the Chinese utility model patent disclosed by the existing publication number CN219376421U: a pulse dust collector that is easy to clean later. The application provides a pulse dust collector body, a motor, a U-shaped frame, a rotating shaft, a collection rod, and a dust outlet pipe, so that it has a rotating collection function. The motor drives the two collection rods to rotate, and pushes the dust that falls on the bottom of the pulse dust collector body into the dust outlet pipe, which makes it more convenient to collect dust and reduces the accumulation of residual dust. However, the bottom of the existing pulse dust collector is generally conical, and the dust in the dust collector can be effectively discharged with the dust discharge valve. At the same time, when the humidity of the gas introduced into the pulse dust collector from the outside is high, after the dust in the gas is intercepted and filtered, some dust will adhere to the inner wall of the dust collector, so that when the pulse spray system is used for cleaning later, only the bag can be cleaned, and the inner wall of the dust collector still needs to be cleaned by entering the dust collector manually when the equipment stops running, which increases the difficulty of personnel cleaning the pulse dust collector, and thus cannot effectively improve the cleaning efficiency of the dust adhering to the inner wall of the pulse dust collector.
