The invention relates to an electrostatic water washing dust removing apparatus, which comprises a housing, wherein the housing is provided with a gas inlet pipe and a gas exhaust pipe, a liquid phase labyrinth is arranged inside the housing, the gas inlet of the liquid phase labyrinth is communicated with the gas inlet pipe, the gas outlet is communicated with the gas exhaust pipe, at least the partial liquid phase labyrinth is immersed in a liquid, the liquid phase labyrinth is formed by straggeredly arranging a plurality of horizontally arranged separation plates, at least the facing-water surfaces of the separation plates are provided with a bristle layer, the upper portion of the liquid phase labyrinth gas inlet is provided with a negative ion device, the discharge electrode in the negative ion device is connected with the positive electrode of a power supply, and the liquid phase labyrinth is an electric conduction body and is connected with the negative electrode of the power supply or the ground. According to the present invention, the wet absorption way is used and the liquid phase labyrinth structure is matched, such that the dust in the air is effectively absorbed, and the indoor absorbable particles are reduced; and particularly the liquid phase labyrinth structure is used so as to prolong the contact time of the air and the liquid, and the negative ion device structure is matched so as to well adsorb the particles into the liquid, such that the dust removing effect is improved.
