[0059] S2: when the dust sensor 52 monitors that the dust concentration in the tunnel reaches a certain concentration, the air suction pump 51 will convey external high-concentration dust gas into the first cavity 11 of the water tank 1, and spray clean water through the nozzle 311 to spray and remove dust, so as to realize timely response of the spray dust removal work;

When the dust sensor 52 monitors that the dust concentration in the tunnel reaches a processing threshold, the controller 53 controls the suction pump 51 to start, so that external dust gas is sucked and delivered into the first cavity 11. At the same time that the suction pump 51 sucks and delivers the dust gas, the controller 53 controls the water pump 32 to start, so that the clean water in the second cavity 12 is delivered into the spray pipe 31 and sprayed out of the spray head 311, forming a spray water curtain in the first cavity 11, which performs spray dust removal on the dust gas delivered into the first cavity 11.
