Abstract
The invention provides an electrostatic precipitation circulating type water film dust removing device and method. The device and the method are characterized in that the top end of a negative electrode electric needle can perform corona discharge under the negative voltage effect to locally ionize air to generate an ionic field; an ionic field area generated by the corona discharge of the top end under the negative voltage effect contains a large number of negative ions which can perform directional movement in an electric field, thus generating ionic wind. According to the device and the method, the dust can be charged through the negative ions, and moreover, the negative ions can be accelerated to impact an electropositive water film under the combined action of coulomb force and the ionic wind; the running water forms a water film which can take away the dust; meanwhile, the negative ions can break protein structures of the surfaces of bacteria and virus, thus achieving the effect of eliminating bacteria and virus; a little ozone is generated inevitably during the corona discharge of the top end, and the solubility of ozone in water is several times that of oxygen, so that the ozone dissolved in the water film can continuously eliminate bacteria and virus in the water film.
