Abstract
An ozone generator for generating ozone by applying a specified process to oxygen by discharge includes a first raw material gas supply unit for supplying the oxygen as a first raw material gas, and a second raw material gas supply unit for supplying an oxide compound gas as a second raw material gas, in which, by excited light, excited and generated by a discharge in the oxygen and the oxide compound gas, the oxide compound gas is dissociated, or the oxide compound gas is excited accelerating dissociation of the oxygen, and ozone is generated. In this way, ozone generation efficiency is raised.
Claims7
An ozone generator comprising:
- a first electrode;
- a second electrode facing the first electrode and defining a discharge area;
- a first raw material gas supply unit for supplying oxygen as a first raw material gas;
- a photocatalytic material on a dielectric substrate located in the discharge area or on the first electrode and absorbing light in a specified wavelength range, or a material transformed into a photocatalyst by a discharge;
- a second raw material gas supply unit for supplying a second raw material gas as an oxide compound gas or generating an oxide compound gas in response to the discharge;
- and
- a third raw material gas supply unit for supplying a third raw material gas which is excited by the discharge and generates excited light to excite the photocatalytic material and the oxide compound gas to generate an oxygen atom, wherein an AC voltage is applied between the first electrode and the second electrode from a power supply to supply discharge power to the discharge area, quantities of the raw material gases are supplied by the first, second, and third raw material gas supply units to a space where the discharge is generated in the discharge area, and ozone is generated.
