Abstract

An electric dust collector of a high dust collection rate is disclosed. A charging section of the electric dust collector includes a first grounding electrode brought into contact with a dust filter, and second grounding electrodes surrounding needle-like discharge electrodes and electrically connected to the first grounding electrode. This structure generates corona discharge between the discharge electrodes and the first grounding electrode as well as between the discharge electrodes and the second grounding electrodes. Thus a discharging area is expanded, and charged dust particles can be collected with a high degree of efficiency.
