[0090] During the cleaning process, the cleaning liquid passes through the eleventh control valve 121 and the twelfth control valve 221, and is used to clean the first balance tank 100 and the second balance tank 200 through the first spraying mechanism 110 of the first balance tank 100 and the second spraying mechanism 210 of the second balance tank 200. During the circulation, the cleaning flow rate and the concentration of acid-base cleaning can be monitored in real time through the flow meter 450 and the conductivity meter 800 to determine whether the cleaning meets the standards.

[0091] (3) Cleaning other small functional devices 10 and the first balance tank 100 and the second balance tank 200 simultaneously: First, add a certain amount of water to the first balance tank 100 and the second balance tank 200 through the interface structure 410. Then, open the first chemical addition control valve 630 or the second chemical addition control valve 660 as required, add a certain amount of acid or alkali to the first balance tank 100, and close the acid-base valve and the pump.

[0092] Open the second control valve 320, the third control valve 330, the fourth control valve 340 and the fifth control valve 350, and start the first cleaning pump 370. At this time, the cleaning liquid is divided into two paths. One path of the cleaning liquid flows from the first balance tank 100 through the second control valve 320, the third control valve 330, the target functional device 10 to be cleaned, and the fourth control valve 340 and then enters the second balance tank 200, realizing the cleaning of other small functional devices 10. The other path of the cleaning liquid flows from the first balance tank 100 through the first control valve 310, the second control valve 320, the third control valve 330, the fourth control valve 340 and the fifth control valve 350 and then enters the second balance tank 200, realizing the cleaning of the first balance tank 100 and the second balance tank 200. Both paths of the cleaning liquid flow into the second balance tank 200 and return to the first balance tank 100 through the seventh control valve 420 at the outlet of the second balance tank 200 and the second cleaning pump 730 to realize cyclic cleaning. During the cyclic process, the cleaning flow rate and the concentration of acid and alkali cleaning are monitored in real time through the flow meter 450 and the conductivity meter 800 to determine whether the cleaning meets the standard.
