Embodiment Construction
[0021] Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. In addition, in each figure, elements having common functions are denoted by the same reference numerals, and descriptions of parts already explained are omitted.
[0022] figure 1 It is a schematic diagram for explaining the principle of this embodiment easily. The mechanical dust removal filter 1 (coarse filter) provided on the main body of the device blocks relatively large (for example, 500 μm or more) dust among the dust a floating in the air. Next, a corona discharge is generated between the positive (high voltage) side electrode 3 of the high voltage power supply 8 provided on the charge unit 6-1 and the negative (ground) side electrode 2-1 thereof, so that the dust b is positively charged, and the dust b is positively charged in the current collection. The positive electrode (high voltage) side electrode 4 of the high voltage power supply 9 and t...
