Technical Field

[0001] The utility model relates to the technical field of dust collector environmental protection equipment, in particular to an air regulating valve for the air inlet pipeline of a double-row bag type dust collector. Background Technique

[0002] A bag type dust collector is a dry dust filtering device, suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the fibrous fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag type dust collector, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified. The structure of the bag type dust collector mainly consists of an upper box body, a middle box body, a lower box body (ash hopper), a dust cleaning system, a dust discharging mechanism and other parts.

[0003] During the actual operation of the existing bag type dust collector, there is a situation where the flue gas in the air inlet pipeline of the middle air duct causes uneven distribution of the air flow rate in each dust removal compartment, which will affect the service life and dust removal efficiency of the whole dust collector.

[0004] The publication number is: CN219355579U, and the name is: An air regulating valve for the air inlet of a bag type dust collector, including: a rotating shaft rotatably connected to the air inlet of the bag type dust collector; a valve plate assembly fixedly arranged on the rotating shaft for rotating with the rotating shaft and adjusting the flow path and flow rate of the air flow in the air inlet of the bag type dust collector during rotation; a limiting assembly fixedly arranged on the rotating shaft for limiting the rotation angle of the rotating shaft. The utility model is applied to the field of environmental protection equipment, has a guiding effect on the dust-containing gas entering the bag type dust collector, enables the dust-containing gas to be evenly filtered through the filter bag, greatly prolongs the service life of the filter bag, and improves the dust removal efficiency of the bag type dust collector.

[0005] The above-mentioned air regulating valve for the air inlet of the bag type dust collector can prolong the service life of the filter bag and improve the dust removal efficiency of the bag type dust collector, but it cannot completely solve the problem of uneven distribution of the air flow rate of the flue gas in the air inlet pipeline of the middle air duct in each dust removal compartment.
