中文摘要：

电源频率和放电管长度是介质阻挡放电（DBD）臭氧产生的两个重要影响因素，针对目前臭氧产生能耗偏高的情况。采用合适的高频高压电源和放电管长度进行实验研究。实验研究了氧气源放电电压、气体流量和相对湿度对臭氧产生的影响。并对系统进行了优化。研究结果表明：臭氧浓度随放电电压增大而增大。随气体流量增大而减少；当流量为200Uh、放电电压为2843V时。臭氧浓度与臭氧产率同时达到相对较高值，臭氧浓度为50．9g／m3时。臭氧产率为102．36g／kWh.

英文摘要：

The power frequency and the length of discharge tube are two important factors for achieving high-efficiency ozone generation. In order to reduce energy consumption in a dielectric barrier discharge reactor, an appropriate power supply and discharge tube length were adopted in the study. Experiments were carded out to investigate the effects of discharge voltage, gas flow rate and relative humidity on ozone concentration, and then optimize it as well. The results show that ozone concentration increases with increasing discharge voltage, and decreases with increasing gas flow rate. The relatively higher ozone concentration and ozone production efficiency are 50.9 g/m3 and 102.36 g/kWh, respectively, at gas flow rate of 200 L/h and discharge voltage of 2 843 V.
