<p>PURPOSE:To enhance ozone removal efficiency by reducing the area of ozone removing activated carbon in a rear part, by arranging an ozone adsorbent or an ozone decomposing catalyst on an ionization electrode or between said ionization electrode and the opposed earth electrode. CONSTITUTION:High voltage is applied not only between ionization electrodes 11, 11'... and opposed earth electrodes 12, 12'... but also between high voltage electrodes 13, 13'... and opposed earth electrodes 12, 12'... and, when a corona current is flowed to the ionization electrodes 11, 11'... and the opposed earth electrodes 12, 12'..., ion wind is generated herein. At this time, air generates dielectric breakdown by the strong electric fields on the surfaces of the ionization electrodes 11, 11'... and a large amount of ozone is generated. In this case, for example, if activated carbons 18, 18'... are wound around the ionization electrodes 11, 11'... or said electrodes 11, 11'... are covered by a catalyst such as platinum, high conc. ozone can be quickly adsorbed and the flow of ozone to air pervious activated carbon 14 in a rear part is reduced.</p> |
