Electric precipitation electric field structure and purifier

Abstract

The invention discloses an electric precipitation electric field structure which comprises a high-voltage electrostatic field which is a cellar structure and a low-voltage electrostatic field. The high-voltage electrostatic field comprises a plurality of cellar dust collecting electrodes and discharge electrodes arranged in the cellar dust collecting electrodes; the low-voltage electrostatic field is arranged behind the high-voltage electrostatic field in series and the low-voltage electrostatic field is a plate-plate type structure. The low-voltage electrostatic field comprises a plurality of dust collecting polar plates and discharge polar plates which are arranged at intervals. The electric precipitation electric field structure also discloses a purifier. The electric precipitation electric field structure not only can ensure charging and dust-collecting effects, but also can distribute the electric field more uniformly due to the high-voltage electrostatic field and the low-voltage electrostatic field which are connected in series front and back. The high-voltage electrostatic field and the low-voltage electrostatic field are designed, so that the energy consumption is low and the purifying effect is good; the dust collecting area, the charging and dust-collecting effects can be effectively enhanced, the treatment effect is improved, and lampblack particle charges are adsorbed to the dust collecting plate and are easily separated and collected, so that the cleaning period is prolonged and the cleaning frequency is reduced.
