[0002] A wet filtering dust removal fan refers to a fan that uses water and a filter layer to cooperate with dust collection to purify the airflow. When working, the dust-containing gas is brought into close contact with the liquid, and the inertial collision of water droplets and particles or the full mixing of water and dust and other effects are used to capture particles, or the particles are enlarged or retained in a fixed container to achieve the effect of separating water and dust.

[0003] At present, the existing wet dust removal fan is equipped with a multi-stage filtering structure to enhance the filtering efficiency. However, after working for a long time, the wastewater formed by the combination of dust in the air and water mist is easy to form sediment inside the casing and is not easy to discharge, which requires frequent cleaning and is relatively troublesome to use.

The sewage enters the sewage collection box 310 through the sewage trough 130, and the sediment and impurities in the sewage are filtered by the filter plate 320. The filter plate 320 is pulled out by pulling the handle 320a, so that the filter plate 320 can be cleaned regularly without frequent cleaning of the inside of the shell 100. Example 2

[0041] Based on Example 1, Figure 1-Figure 3An impurity filter screen 120a is provided on the outer wall of the mounting groove 120 to prevent impurities with larger diameters in the outside air from entering the shell 100. A water filter screen 150 is provided inside the shell 100 on the side of the atomizing nozzle 220 away from the dust filter screen 110 to prevent water mist from being discharged from the shell 100 through the flowing air, thereby causing a waste of water resources or causing humidity in the surrounding area. A water retaining ring is provided on the side wall of the water filter screen 150 to prevent sewage inside the shell 100 from flowing out through the opening at the end of the shell 100.
