Abstract

PURPOSE:To prevent the generation of harmful NOx in an apparatus for forming corona discharge between a metallic rod and a metallic foil in a glass tube and discharging the produced ozone from the discharging port with a fan placed at the back of a casing, by feeding dehumidified air to the electrode. CONSTITUTION:The metallic rod 26 and the glass tube 28 of the O3 and air ion generation part 23 is placed in a sealed small casing 32 having tapered tip and furnished with the port 31 to discharge O3, etc., and the backside or the lateral side of the casing 32 is connected to the pipe 33 to introduce dehumidified dry air (having a dew point of <=-60 deg.C). When dehumidified dry air is introduced through the pipe 33 into the casing 32 under the corona discharge between the rod 26 and the metallic foil 27 in the tube 28, O3 and ion are generated between both electrodes and are discharged from the discharging port 31. At the same time, air is sucked from the room through the rear part of the casing 16 with the fan 19, and mixed with the generated O3 and ion in the discharging port 31 before discharge. The mixture having reduced O3 concentration is discharged and diffused from the discharging port 17 into the room.
