Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a cyclone air intake type water filter dust collector. Background Art

[0002] As the environmental protection standards of industry become higher and higher, the requirements for the treatment of dusty flue gas generated in industrial production are also getting higher and higher. The existing dusty flue gas treatment equipment is roughly divided into two types: dry type and wet type. The wet dust collector can also be called a water filter dust collector. The wet type mainly uses water to absorb dust particles in the gas. The dust-containing gas is sent to the inside of the dust collector filled with water. The gas impacts the water surface to make the dust particles separate from the gas and be absorbed by the water. However, the existing water filter dust collector always has the following problems in use:

[0003] The existing water filter dust collector uses the method of dust-containing flue gas impacting the water surface and using inertia to separate the dust particles. However, this method cannot drive the water to flow effectively, so that the dust particles in the dust-containing flue gas accumulate more and more on the water surface over time. The inability of water to flow effectively will cause the dust particles to form a dust film on the water surface, which makes it impossible for water to adsorb dust, thereby affecting the dust removal effect.

[0004] Chinese patent application number 2021108239735 discloses a reflux water filter dust collector, which uses the dust reflux separated by cyclone to impact and disturb the water body to prevent the formation of dust film on the water surface. However, its disturbing effect on the water body is limited. Utility Model Content
