    (54) Electric precipitator


    (57) An electric precipitator comprising a plurality of discharge members (3) each having a plurality of spaced main discharge electrodes (3b) protruded from each longitudinal edge of the discharge member (3) and a plurality of spaced additional discharge electrodes (3c) protruded from each longitudinal edge of the discharge member (3) and arranged with the main discharge electrodes (3b) in an alternating manner, a plurality of charge members (4) each charge member having a plurality of spaced main charge electrodes (4a) formed at each longitudinal edge of the charge member (4) to have an arc groove shape and a plurality of spaced additional charge electrodes (4b) formed at each longitudinal edge of the charge member (4) to have an arc groove shape and arranged with the main charge electrodes (4a) in an alternating manner. Each additional discharge electrode (3c) has a length different from that of each main discharge electrode (3b). Each additional charge electrode (4b) has an arc length different from that of each main charge electrode (4a). An activated carbon filter is disposed to filter secondarily the charged dust particles and remove odor from the air.
