<p>Provided is an apparatus for controlling static electricity. The apparatus uses ultra-fine particles with positive polarity and utra-fine particles with negative polarity. The apparatus comprises one or more capillary for spraying liquid supplied from a liquid supply. A high voltage generator with positive polarity and a high voltage generator with negative polarity are connected to the capillary. Also, a ground electrode is spaced apart from the capillary to form an electric field in cooperation with the high voltage generators. The static electricity is easily controlled by the ultra-fine particles with positive polarity and the ultr-fine particles with negative polarity.</p> |
