Embodiment Construction

[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] The ozone generator is a device used to produce ozone gas. According to the way of generating ozone, the ozone generator is mainly divided into three types: high-voltage discharge type ozone generator, ultraviolet irradiation type ozone generator and electrolytic type ozone generator. It should be noted that the ozone generators involved in the embodiments of the present invention are all high-voltage discharge ozone generators.

[0034] For the ozone generator involved in the embodiment of the present invention, its core component is a discharge chamber, and the discharge chamber is used to generate ozone according to an applied voltage. It should be noted that wh...

Abstract

The invention provides a resonant frequency tracking method and device for an ozone generator power supply. The method comprises acquiring an acoustic wave signal in a discharge chamber of an ozone generator and working frequency of an ozone generator power supply so that the resonant frequency of the discharge chamber and the working frequency of the ozone generator power supply are monitored, and if the working frequency of the ozone generator power supply and the resonant frequency of the discharge chamber are different, adjusting the working frequency of the ozone generator power supply sothat the working frequency of the ozone generator power supply is the same to the resonant frequency of the discharge chamber. The method and device can determine if the discharge chamber is in a resonant state through the acoustic wave signal in the discharge chamber and the working frequency of the ozone generator power supply, and if the discharge chamber is in a resonant state, the working frequency of the ozone generator power supply is adjusted so that the working frequency of the ozone generator power supply is the same to the resonant frequency of the discharge chamber. The method anddevice are simple, safe and efficient and realize the maximum ozone yield in a complicated and changeable environment.

Description

technical field [0001] The invention relates to the technical field of ozone preparation, and more specifically, to a method and device for tracking the resonant frequency of an ozone generator power supply. Background technique [0002] Dielectric barrier discharge (DBD) is a mainstream method for producing ozone with high efficiency and environmental protection. The key to the generation of ozone in DBD lies in the realization of the AC-DC-AC of industrial frequency power supply through the dedicated high-frequency power supply composed of analog and digital circuits. A series of transformations generate the resonant frequency voltage signal required by the DBD discharge chamber, thereby maximizing the production of ozone. However, the resonant frequency of the discharge chamber is seriously affected by factors such as the pressure of the discharge chamber and the temperature of the discharge chamber, so frequency tracking technology is required to keep the operating frequ...
