摘要：

This work studies the characteristics of electrical discharge, optical emission spectroscopy and ozone production of an air-fed dielectric barrier discharge reactor. In particular, the reactor utilizes water as the high voltage electrode and the grounding electrode. Results show that when the applied peak-to-peak voltage is increased from 16.8 kV to 26.8 kV at 10 kHz, the specific input energy is increased from 19.0 J/L to 664.9 J/L. The maximum ozone generation efficiency reaches about 155 g/kWh with an ozone concentration of around 1549 ppm. The results also show that at a peak-to-peak voltage of 24.0 kV, the typical rotational temperature is 306 +/- 5 K. In addition, during a 400 min stability test with ozone concentrations up to about 6000 ppm, the ozone generation efficiency is stabilized at around 106 g/kWh. The reactor can provide optimized control of the gas temperature and realizes energy-efficient ozone generation.
