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.
