The present invention relates to an electric precipitator and an air cleaning system including the electric precipitator. An electric precipitator according to the present invention includes: a charge unit which charges dust particles in air going through the charge unit into a positive electric charge and a negative electric charge respectively by disposing a positive electrode to which a positive voltage is applied, a negative electrode to which a negative voltage is applied, and charge corresponding electrodes such that the charge corresponding electrodes cover an area of each of the electrodes, thereby forming a corona discharge between the electrodes and the charge corresponding electrodes; and a dust collecting unit including a negative electrode dust collecting plate and a positive electrode dust collecting plate which are applied with a negative electrode high voltage and a positive electrode high voltage respectively and are disposed such that the negative electrode dust collecting plate and the positive electrode dust collecting plate are crossed to collect the dust that are charged with a positive electric charge and a negative electric charge in the charge unit. Accordingly, an electric precipitator according to the present invention is capable of doubling an effective dust collecting area compared to a conventional electric precipitator, and is capable of preventing corrosion, ozone generation, electric shock and others by coupling non-conductive members to an outer circumferential surface of conductive members composing each of the dust collecting plates. |
