<p>PURPOSE:To constitute a dust collection part at low cost and to omit labor hour of cleaning by constituting the dust collection part of adsorptive liquid which consists of water or a mixed liquid of water and a surfactant and is brought into contact with charged particles. CONSTITUTION:The air sucked into a box body 21 is passed through a charged part 1 impressed with DC high voltage and dust particles contained in the air are electrified and these particles are attracted on a dust collection part impressed with negative voltage. In this case, the dust collection part is constituted of adsorptive liquid 10 which consists of water or a mixed liquid of water and a surfactant and is brought into contact with the above-mentioned charged particles. As a result, the dust collection part is constituted at low cost and also labor hour of cleaning is omitted.</p> |
