A. preparation before dust removal: keeping the second to fourth control valves in a closed state, opening the first control valve, injecting clean water into the water spraying bin through the water adding port, enabling the water to enter the dust removing bin through each atomizing nozzle, stopping injection until the liquid level of the water in the dust removing bin reaches the lower end of the dust blocking plate, and closing the first control valve;
B. dust removal work: opening a third control valve and starting a centrifugal impeller pump, wherein the impeller rotates to drive water in the dust removal bin to form a hydrodynamic vortex, and the water pump is led into a third pipeline, negative pressure is formed in the dust removal bin at the moment, so that dust-containing air around the dust removal box body enters the dust removal bin from the air suction port under the action of the negative pressure, and the sucked dust-containing air flow is blocked by a dust plate to prevent the dust from flowing downwards to contact with the water, so that the water adsorbs the dust; meanwhile, water entering the third pipeline is conveyed to the water spraying bin through the three-way joint and the first pipeline, and finally the water forms fog drops through the atomizing nozzle to enter the dust removing bin, the fog drops can adsorb dust particles suspended in the dust removing bin and settle into the water together with the dust particles, and the gas after dust removal is discharged out of the dust removing box body through the gas outlet, so that the circulation is continued, and the efficient dust removing process is realized;
C. dust and mud cleaning and water body recovery: after the dust removal work is finished, the third control valve is closed, the centrifugal impeller pump is stopped, the second control valve and the fifth control valve are opened, dust contained in the dust removal bin respectively enters the first dust and mud cleaning device and the second dust and mud cleaning device, after the dust removal bin is kept stand for a period of time, dust and mud formed by the dust are deposited to the bottoms of the first dust and mud cleaning device and the second dust and mud cleaning device, the first dust and mud cleaning port and the second dust and mud cleaning port are opened to discharge and collect the deposited dust and mud, and the water body is recovered; and after the completion, opening a third control valve and a fourth control valve to ensure that the residual water in the dust removal bin is discharged and recovered through a third pipeline and a second pipeline, and discharging and recovering the residual water in the first pipeline through the second pipeline.
