| 摘要 |
A charging device for an electric dust collection of the present invention comprises: a first electrode unit (110) including a tubular member (111), which has a hollow tube shape with a hollow inside and to which one of a positive (+) electrode and a negative (-) electrode is applied; and a second electrode unit (120), which includes a protrusion (121) protruding toward the center of the tubular member (111) and to which the other of the electrodes is applied, so a corona discharge is further activated at the protrusion of the second electrode unit (120), thereby maximizing a charging effect and sufficiently ensuring a space in which air flows. |
