Description

Technical Field

[0001] The utility model relates to the technical field of tube bundle dust collectors, in particular to a tube-type cyclone tube bundle dust collector. Background Art

[0002] The tube bundle dust collector is used to remove and purify dust substances carried by the saturated clean flue gas in the wet desulfurization tower.

[0003] The tube bundle dust collector mainly relies on the characteristic that the low-temperature saturated clean flue gas at the top of the absorption tower contains a large number of fine droplets. It uses the high-speed movement of a large number of fine droplets to increase the probability of fly ash particles colliding with the droplets, and the droplets and fly ash particles condense to achieve the capture and removal of this part of extremely small fly ash dust and droplets.

[0004] For example, the utility model patent with publication number CN211987673U discloses a four-liquid collecting tube bundle dust collector, including a dust collector tube body, a main shaft is vertically inserted from top to bottom at the inner center of the dust collector tube body, two first annular reinforcement ribs are arranged on the outer wall of the dust collector tube body from top to bottom in sequence, and compression reinforcement ribs are vertically arranged one by one on the two first annular reinforcement ribs surrounding the outer wall of the dust collector tube body.

[0005] During use, the above-mentioned prior art can install water mist nozzles immediately at the through holes on each dust collector pipe body to merge the fly ash particles and water mist droplets in the flue gas, and then adsorb and filter the smoke through a microporous filter plate and an activated carbon filter chamber. However, multiple water mist nozzles are fixedly arranged on the dust collector pipe body to spray water mist toward the center of the pipe body. The area between the water mist nozzles will inevitably have spraying dead angles, which will affect the mixing effect of the flue gas and water mist. Utility Model Content
