1. and (5) a shutdown mode. The water pump 37 and all control valves are in a closed state and the dust removal water supply is not started.

2. And a static pressure box direct injection mode. The control device 5 sends out a signal to open the water inlet control valve 311 and the water discharge control valve 321 by selecting the hydrostatic tank direct injection mode by the direct injection mode selecting part 51, and the rest control valves are kept closed. The dust removing water directly enters the spraying device 14, is sprayed into the static pressure tank 10 through the spraying device 14, sprays and falls dust, and is discharged out of the system from the first water outlet 12.

The control device 5 sends out a signal to turn on the water pump 37, the bypass control valve 361, the second circulation control valve 341 and the drain control valve 321, and the circulation tank 20 drains water through the bypass line 360, the second circulation line 340 and the drain line 320, so that after a period of time, the operation is put into a stop mode.

Whether the dedusting water supply system is in a static pressure tank direct injection mode, a static pressure tank circulation mode, a circulation water tank water supplementing mode or a circulation water tank water draining mode, once the water level of the static pressure tank 10 exceeds a third monitoring water level, the control device 5 sends out a signal to close the water inlet control valve 311 and the first circulation control valve 331, so that continuous water inlet in the static pressure tank 10 is avoided, and alarm information is generated.
