Abstract

The invention provides a yield-constant and concentration-adjustable ozone generator. The ozone generator comprises a modulating high-voltage alternating current power supply and a discharge chamber, the modulated waveform of the modulating high-voltage alternating current power supply is the combination waveform of sine waves with the duration of TON and termination waves with the duration of TOFF, the frequency of the combination waveform is fM, the duty ratio D is changeable, the quantity of the sine waves in the TON is N, and the frequency of the sine waves is fAC. The yield-constant and concentration-adjustable ozone generator realizes the adjustment of the size of the duty ratio through adjusting one or more of the fAC, fM and N in order to change the concentration of high energy electrons in a discharge space and the existence time of the high energy electrons in a cycle period, so the concentration of ozone is adjusted without changing the yield of the ozone in order to reach the ozone concentration-adjustable and yield-constant effects.

Description

technical field [0001] The invention belongs to the technical field of ozone generators, and in particular relates to an ozone preparation method with constant yield and adjustable concentration. Background technique [0002] Ozone has strong oxidizing and disinfecting properties and does not produce secondary pollution, so it is widely used in urban and industrial water treatment, sewage and wastewater treatment, food processing and medical industries. In order to obtain a high concentration of ozone and an efficient ozone generator, domestic and foreign scholars have conducted extensive research on the ozone yield and the performance of the ozone generator based on different discharge systems. The research on ozone generators generally focuses on the improvement of ozone yield. At present, the highest ozone yield is 783g / kWh, which is obtained by Song under the condition of mixed discharge, and the ozone concentration is 36.78g / m 3 ; Secondly, the ozone production rate is...
