<p>PURPOSE:To remove aerosol particles efficiently by ionizing gas as a positive/ negative ion pair by irradiating an atmospheric gas with radiation, then allowing either of these ions to act on an aerosol to charge the aerosol particles electrically, and allowing the aerosol particles to deposit or to be captured. CONSTITUTION:An ion pair ionized by radiation is separated as a positive and a negative ion, then an aerosol is allowed to act on the separated and single polarized ion, and the aerosol is separated. Thus, the aerosol is removed efficiently by allowing it to deposit or be captured by a filter. That is, DOP (dioctyl phthalate) is stored in a dispensing syringe-type pump and then is supplied to an aerosol generator 6. In this case, large-size particles of sprayed aerosol are trapped and particles gasified to the size of 1mum or below generate. In addition, the electric charge of the particle is neutralized by allowing the aerosol to pass through an aerosol neutralizer 7 as the atomized aerosol may possibly be electrically charged, and further, the particles are allowed to pass through the single polarized cell 9 of an irradiation device 8.</p> |
