Abstract:
An ozone generating apparatus is provided, which comprises an ozone generating unit including tow electrodes (2, 31) mutually opposed to generate discharge in response to high voltage applied therebetween, a dielectric (4) interposed between the electrodes and a gas supply mechanism to supply an oxygen-rich gas between the electrodes (2, 31) so as to generate ozone by the discharge. The discharge space (5) has a gas pressure of 101325 Pa (1 atm) or more and a discharge gap length of 0,4 mm or less. Further the product of the gas pressure and the discharge gap length is about 4000 Pa · cm (30 Torr · cm) or less.
Abstract:
La présente invention se rapporte à un appareil générateur d'ozone pour la stérilisation ou la désinfection dans lequel l'ozone est généré sous forme gazeuse par décharge corona dans un générateur haute tension à partir d'air, caractérisé en ce qu'il comprend des moyens pour réchauffer et propulser un gaz inerte initialement sous forme liquide et le mélanger à l'ozone produit, de sorte que le gaz inerte constitue un gaz porteur de l'ozone sortant de l'appareil sous forme d'un mélange à une pression totale comprise entre 2 et 10 bar et à une température inférieure d'au moins 10°C à la température ambiante.

Abstract:
An ozone generating apparatus comprises at least one ozone generating unit which includes:
two electrodes mutually (2, 31) which are opposed to generate a discharge in response to high voltage applied therebetween; at least one dielectric (4) interposed between the electrodes to provide insulation between the electrodes; and a gas supply mechanism to supply an oxygen-containing gas between the electrodes so as to generate ozone by the discharge. In this unit a spacer (61) is inserted into a discharge space (5) causing the discharge to ensure a predetermined distance or more between the electrodes of the ozone generating unit, and the spacer forms a non-discharge portion where no discharge occurs.
