FILTER ELECTRIFICATION PROCESSOR AND FILTER ELECTRIFICATION PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a filter charging processor that can uniformly electrify a whole cubic filter by making charged particles reach a deep part of the filter.SOLUTION: The filter charging processor comprises a pair of electrodes, which form a drift electric field by impressing voltage across the electrodes and an electrified fine particle generating part that generates electrified fine particles having smaller specific charges than electrons and ions to feed them to the drift electric field, and irradiates a processing object filter installed between the electrodes with electrified fine particles drifted by the drift electric field.
