Spraying device and process for building construction flying dust control

The invention relates to the technical field of spraying equipment, and particularly discloses a spraying device and process for building construction flying dust control. The spraying device comprises a plurality of bases, electric push rods are connected to the bases, connecting blocks are fixedly connected to the tops of the electric push rods, mounting blocks are arranged above the connecting blocks, and the mounting blocks are detachably connected with the connecting blocks; water pipes are fixedly connected to the mounting blocks, atomizing nozzles are mounted on the water pipes, a plurality of rollers are mounted at the bottom of the base, a plurality of inserting rods are further fixedly connected to the bottom of the base, and a hose is connected between every two adjacent water pipes. When the construction position changes, the base is moved to be close to the construction position by moving the base, the electric push rod and the water pipe, targeted dust falling can be conducted on the constructio
