Electrostatic spraying and dust-removing system

The invention relates to an electrostatic spraying and dust-removing system. One end of a shell is an inlet of a dust-removing system while the other end of the shell is an outlet of the dust-removing system; an air flow distributor, an electrostatic spraying device, a filtering dust-collecting and washing device and a water separator are arranged in the shell orderly from the inlet to the outlet; at least one atomizing nozzle is connected to a water supply pipe in the electrostatic spraying device, a high pressure static ring is arranged in front of each atomizing nozzle; the high pressure static ring is connected with a high pressure static generator at the outer part of the system through a lead; a filler is arranged in the filtering dust-collecting and washing device, and the upper part of the filler is provided with a water pouring distributor; the water pouring distributor is connected with a system external water supply pipe through a water pipe; and the bottom part of the filler is provided with a water collecting disk, and the water collecting disk is provided with a water draining pipe. The system can satisfy the dust removing requirement of grains in different sizes in air, and has a relatively good effect to filter the powder dust with the grain diameter being more than 0.1 micro meters.
