PURPOSE:To prevent the lowering in dust collection capacity by always cleaning a discharge electrode to generate a proper corona current, by performing the hammering of the discharge electrode at the time of non-charge by simple sequence. CONSTITUTION:When the current of the discharge electrode of an electric dust collection apparatus is reduced to a set value (e.g., 80% of a start early stage) or less, charging to the discharge electrode is stopped to perform the hammering of the discharge electrode. Thereafter, simple sequence for again charging the aforementioned discharge electrode is repeated. By this method, dust is released from the discharge electrode and the corona current of the discharge electrode is always restored to the current at the time of cleaning.
