摘要
臭氧由于具有强氧化性,在众多领域已经得到了广泛的应用。本文通过试验研究了介质阻挡放电产生臭氧的特性。结果表明:外加电压增大时,臭氧浓度和产速都不断增大,臭氧产率则是先增长,达到最大值后又开始略微下降;气体流速增大时,臭氧浓度不断减小,而臭氧产速和产率都是先增长,达到最大值后又开始下降;电源频率在5.0～9.9kHz范围内改变时,臭氧浓度、产速和产率变化不明显;当电介质厚度不变时,在0.3～0.5mm范围内改变间隙厚度,小间隙厚度优势不明显。
Ozone has been widely used in many fields due to its strong oxidation ability. Under the condi- tions of experiments, the results shown are as follows： with an increasing applied voltage, both ozone con- centration and ozone generation rate increase, while ozone generation efficiency increases at first, reaching the peak value and then decreases slowly; with an increasing gas flow rate, ozone concentration decreases, while both ozone generation rate and ozone generation efficiency increase at first, reaching the peak value and then decrease;when power supply frequency is changed in the range from 5.0 kHz to 9.9 kHz,no ap- parent laws of ozone concentration, generation rate and generation efficiency are found; and when gap spac- ing is changed in the range from 0.3 mm to 0.5 mm and dielectric thickness is unchanged, shorter gap does not show better effect.
