Abstract

An ozone generating apparatus including a discharge assembly having a common earth electrode (2) and high-voltage electrodes (3) disposed in opposition to each other with disk-like dielectric members (300) being interposed therebetween for generating electric discharge by applying a high voltage across the electrodes. A gas containing oxygen is supplied to discharge spaces (5) defined between the electrodes for generating ozone under the action of electric discharge. The discharge assembly includes a plurality of discharge cells (10a, 10b, 10c) constituted by disposing at least one of the dielectric member and the high-voltage electrode in a corresponding number relative to the earth electrode in common. A plurality of discharge assemblies are stacked and secured together to constitute a block. A plurality of blocks are stacked and secured together to constitute a module. An ozone generating apparatus of a large capacity easy to effectuate assembling and maintenance is realized in a compact structure.
