The impeller 6 automatically rotates under the flushing of the cleaning water, and the cleaning water enters the impeller cavity from the second nozzles 11 on both sides of the impeller 6 to flush the impeller 6. The rebounded cleaning water moistens and flushes the shell surface of the impeller 6. At this time, the first damper 4 and the second damper 8 are in a closed state, which can prevent water droplets and water stains after flushing from entering the connected dehumidifying pipe. The sewage after flushing enters the drainage trough 16 along the sewage pipe 23. During cleaning, the liquid level detector 13 detects the liquid level inside the impeller cavity.

When the liquid level detector 13 detects that the water level has dropped, it is cleaned again with cleaning water. The liquid level detector 13 is connected to the steam-water cleaning pipe 24 and the air-pressure cleaning pipe 25 through the fifth angle valve 17 and other valves. During the cleaning process, the fifth angle valve 17 is opened, and the steam-water cleaning pipe 24 and the air-pressure cleaning pipe 25 clean and purge the liquid level detector 13. After cleaning is completed, it is cleaned again. When the cleaning and blowing are completed, the first damper 4 and the second damper 8 are opened, and the motor on the dehumidification fan is also turned on, the fourth angle valve 15 is opened, and the other valves are closed, and the remaining water stains are removed for the next step of dehumidification. When the inspection finds that the scale is large and hard, the first regulating valve 1 is opened, steam enters the first proportional control valve 2, and the cleaning water enters from the third regulating valve 22 and merges and mixes in the first proportional control valve 2, passes through various valves, enters the annular pipe 7, and is sprayed from the second nozzle 11 on the annular pipe 7 to clean the impeller 6 and the impeller cavity. After cleaning, compressed air is used for cleaning and relevant extraction work is carried out in a timely manner.

[0041] When the dehumidifying fan is to be in the cleaning mode, the second angle valve 21 is opened, and at the same time the fourth angle valve 15, the fifth angle valve 17, the seventh angle valve 19, the sixth angle valve 18, and the eighth angle valve 20 are in the open state, and the other valves are in the closed state, and the compressed air blows the impeller 6 and the impeller cavity.
