In the above configuration, when the dust collecting part DC high voltage application power supply 14 is in the off state, no electric field is generated in the dust collecting part 7,
Therefore, no Coulomb force is generated. In this state, when the charging unit DC high voltage application power source 6 is turned on, corona discharge occurs in the charging unit 3, and due to the discharge, ■ions are generated and flow into the dust collection unit 7, but the dust collection unit Since no electric field is applied to 7, it also reaches the surface of the insulating film 10 and neutralizes the opposite charge attached to the surface. After a certain period of time (approximately 1 minute), the B contact 21 of the timer 20 is restored by the action of the timer 20, and the DC high voltage application power source 14 of the second dust collection section is put into operation, thereby generating an electric field in the dust collection section 7. Since the opposite charges on the insulating film 10 covering the flat electrode 9 to which DC high voltage is applied have already been neutralized and removed,
By maintaining the Coulomb force without reducing the electric field strength, it is possible to maintain high efficiency without reducing the dust collection efficiency.

Conductive wave-shaped spacers 12 are formed on both sides of the flat plate, and the flat electrode 9 is opposed to the dust collecting electrode 11 with the spacer 12 and the insulating film 10 interposed therebetween. The thickness of the spacer 12 can be reduced by overlapping and forming insulating parts 16 at both ends of the dust collecting electrode 11 with small intervals, and by overlapping the two opposing electrodes and winding them in a spiral shape. In addition to achieving low pressure loss, spacer 1
By making 2 electrically conductive, it also serves as a dust collecting electrode, resulting in the effect of making it more compact.

である。Furthermore, at the start of operation, the timer 20 turns off the DC voltage application power supply 14 for the dust collection section for a certain period of time, and forms a power supply circuit that turns on only the charging section DC voltage application power supply 6, thereby applying high DC voltage. The opposite charge attached to the surface of the insulating film 10 covering the flat electrode 9 is
It can be neutralized at the initial stage of operation, and when the dust collector DC voltage application power supply 14 is turned on, the opposite charge on the surface of the insulating film 10 maintains the Coulomb force without weakening the electric field strength, thereby preventing a drop in dust collection efficiency. This results in a preventive effect.
