摘要：

为提高介质阻挡放电产生臭氧的浓度和产量,文中研究了不同方波脉冲模式下介质阻挡放电产生臭氧的特性。文中对系统放电特性进行分析,计算系统放电功率,研究其在不同极性、不同频率和不同脉宽下产生臭氧的浓度和产量,并对其产生的结果进行了分析和讨论。研究结果表明,在施加正负极性方波脉冲时,臭氧浓度最高,为8.8 g·Nm^-3;在施加正极性方波脉冲时,臭氧产量最高,为55 g·kWh^-1。随着频率的增加,臭氧浓度和产量均呈现先增加后下降趋势。在放电频率为1 kHz时,臭氧浓度最大;在放电频率为1.5 kHz时,臭氧产量最高。在其它参数一定的情况下,随着脉宽的增加,臭氧浓度缓慢增加,臭氧的产量基本无变化。

Abstract:

In order to improve the concentration and output of ozone produced by dielectric barrier discharge, the characteristics of ozone produced by dielectric barrier discharge under different square wave pulse modes are studied in this study. The discharge characteristics of the system are analyzed, the discharge power of the system is calculated, and the concentration and output of ozone produced under different polarity, frequency and pulse width are studied. The results are analyzed and discussed. The results show that the ozone concentration is the highest (8.8 g·Nm^-3) when positive and negative square wave pulses are applied, while the ozone yield is the highest (55 g·kWh^-1) when positive square wave pulses are applied. With the increase of the frequency, the ozone concentration and production show a trend of first increasing and then decreasing. When the discharge frequency is 1 kHz, the ozone concentration is the highest, and when the discharge frequency is 1.5 kHz, the ozone production is the highest. Under the condition that other parameters are fixed, the ozone concentration increases slowly with the increase of pulse width, and the output of ozone basically remains unchanged.

Key words: dielectric barrier discharge, low temperature plasma, square wave pulse, different pulse modes, discharge characteristics, accumulated charge, ozone concentration, ozone yield
