Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust removal equipment, in particular to a bag type dust removal device. BACKGROUND

[0002] In the process of production, enterprises will produce a lot of dust, which will cause damage to the environment and harm to human health if directly discharged. Therefore, the dust in the air needs to be filtered. The existing technology usually uses filter cartridges or filter bags to filter dust.

[0003] The existing dust removal methods mainly include dry dust removal and wet dust removal. Due to the defects of high energy consumption, large water consumption, and complex sewage treatment of wet dust removal, dry dust removal is more and more favored by everyone. In dry dust removal, the bag type dust removal device is widely used due to its high dust removal efficiency, low energy consumption, and long service life. However, after long-time continuous use of the traditional bag type dust removal device, dust will adhere to the outside of the bag. If these dusts are not cleaned in time, the inside of the device will be blocked, which will affect the dust cleaning effect and efficiency. The bag type dust removal device on the market usually uses high-frequency vibration or pulse blowing system to remove the dust deposited on the surface of the filter bag to restore its filtering capacity. However, high-frequency mechanical vibration not only easily leads to fatigue fracture of the filter bag fibers, but also produces strong vibration and noise. Pulse blowing not only needs to consume a large amount of clean gas, but also is difficult to ensure that the blowing gas flow fully and uniformly covers the surface of the filter bag, resulting in poor cleaning effect.

[0004] Chinese patent CN204768047U discloses a filter cartridge dust collector in the field of dust removal devices. The filter cartridge dust collector includes a dust removal box body, a dust collecting hopper is arranged on the lower side of the dust removal box body, a dust inlet is arranged on the lower end of the dust removal box body, an air outlet is arranged on the upper end of the dust removal box body, a partition plate is arranged inside the dust removal box body, a clean air chamber and a dust filtering chamber are formed above and below the partition plate, respectively, a filter cartridge is vertically arranged in the dust filtering chamber, the upper end of the filter cartridge is open and connected with the clean air chamber, a guide plate is arranged in the dust filtering chamber, a nozzle is arranged in the clean air chamber corresponding to each filter cartridge, the jet direction of the nozzle is arranged corresponding to the opening of the filter cartridge, the air inlet of the nozzle is connected with the air outlet of a spray rod, the air inlet of the spray rod is connected with a gas storage bag through an electromagnetic valve, the control interface of the electromagnetic valve is electrically connected with a pulse control instrument, the structure is compact and convenient to clean, the dust removal efficiency is high, the device is environmentally friendly and clean, and can be used for filtering and collecting dust in the process of grain conveying and processing.

[0005] The device realizes the cleaning of the dust on the bag by the way of multiple rows of nozzles, that is, by the nozzles above each bag to blow back the bag, but the air flow pressure of the nozzles gradually decreases from the center to the edge of the filter cartridge from top to bottom, which causes the dust at the bottom edge of the bag to be not completely cleaned, if the air flow pressure of the filter cartridge edge is increased by increasing the air flow pressure of the nozzles, the air flow impact overload at the bottom center of the bag will be caused to accelerate the wear of the bottom of the bag, in addition, the dust collector cannot work normally during the back blowing process, which greatly affects the production efficiency. SUMMARY
