Abstract

ABSTRACT The oxidation of ozone is very strong, and the products of oxidative decomposition will not cause secondary pollution, so the ozone has become widely used. Dielectric barrier discharge (DBD) is the main method of ozone generation. In recent years, the addition of outfield in the DBD is used to improve ozone generation. In this paper, a needle-plate DBD ozone generator with magnetic field enhanced was designed and manufactured. The authors found the magnetic field could significantly increase the number and amplitude of current pulses, discharge current and the discharge power. The magnetic field did not change the initial discharge voltage. With the discharge voltage increased, the enhancement of magnetic field on ozone concentration was more obvious while on ozone yield was very small. The maximum increment of ozone concentration was 35.4%. With the discharge frequency increased, the magnetic field had a more positive impact on the ozone concentration. And with the same gas flow rate increased, the ozone concentration was increased by the magnetic field. Keeping the SIE constant, the ozone concentration and ozone yield at higher discharge frequency was lower than those at lower discharge frequency. With the increase of SIE, the enhancement effect of magnetic field on ozone concentration would increase.

磁场对针板式DBD臭氧发生器多参数的影响

臭氧的氧化性很强，氧化分解后的产物不会造成二次污染，因此臭氧得到了广泛的应用。介质阻挡放电(DBD)是臭氧生成的主要方法。近年来，在DBD中增加外场是为了改善臭氧的产生。本文设计并制造了一种磁场增强针板式DBD臭氧发生器。研究发现，磁场能显著增加电流脉冲数和幅值，增加放电电流和放电功率。磁场没有改变初始放电电压。随着放电电压的增加，磁场对臭氧浓度的增强更明显，而对臭氧产率的影响很小。臭氧浓度最大增幅为35.4%。随着放电频率的增加，磁场对臭氧浓度的影响越显著。在相同气体流速增大的情况下，磁场对臭氧浓度的影响增大。在SIE一定的条件下，高频率放电时臭氧浓度和臭氧产率均低于低频率放电时。随着SIE的增大，磁场对臭氧浓度的增强作用增强。
