The invention relates to the field of a spraying device, and aims at providing a multifunctional electrostatic water mist spraying machine for controlling atmospheric pollution. The multifunctional electrostatic water mist spraying machine for controlling the atmospheric pollution comprises a spray rod, a spray nozzle, an electrostatic generator, a liquid pump, a motor, an automatic control device and a water pipe, wherein the motor is connected with the liquid pump, the liquid pump is used for pumping and conveying external liquid to the electrostatic generator through the water pipe, the electrostatic generator is used for charging the liquid, the spraying rod is connected with the electrostatic generator through the water pipe, and the spray nozzle is arranged on the spray rod. The multifunctional electrostatic water mist spraying machine for controlling the atmospheric pollution has the advantages that the water mist charges can be better combined with contaminants in the air, so that the atmospheric pollution in the ambient environment is eliminated; in addition, the spraying device can automatically rotate, meanwhile, the spraying at any angle around the axis can be realized through regulating the transverse and longitudinal directions, the high-space spraying operation can be completed, in addition, the spraying is uniform, the atomization is thorough, small water drops are prevented from being formed around the spray nozzle, the spraying dust removal from top to bottom is realized, and greater space is influenced in once spraying.
