Efficient dust removal equipment for building construction site

The invention relates to the technical field of dust removal equipment, in particular to efficient dust removal equipment for a building construction site. The efficient dust removal equipment comprises a water tank, water outlet valves are fixedly connected to the inner walls of the two ends of the bottom of the water tank, and a rotating shaft seat is fixedly connected to the center of the bottom of the water tank; through the first water suction pump, the water conveying hose and the second water suction pump, a water source used for dust removal can be quickly conveyed to the spraying structure, the physical strength and time of workers can be saved, dust in air can be removed through mist water drops by arranging the spraying head, waste of the water source can be reduced, and the environment is protected. Meanwhile, the multiple sets of spraying heads are arranged, the dust removal range can be expanded, dust floating in the air can be absorbed and treated through the exhaust fan, and therefore the dust
