Abstract :
Experiments were carried out to study the effects of peak voltage and gap width on ozone generated by proper high frequency and high voltage power supply. The results show that the corona inception voltage are 4100 V, 6500 V and 8040 V when the gap width are 1 mm, 2 mm and 3 mm, respectively. The highest volume fraction and production efficiency of ozone are 24.55×10-3 and 134 g/kWh with a gap width of 1 mm. The volume fraction of ozone generated is twice than an ozone generator (famous brand in China), while the production efficiency is equal to it. The simultaneous removal of NOx/SO2 by O3 oxidation was investigated by experiment. In the assistance of wet scrubber, the SO2 removal efficiency is nearly 100% and the NOx reduction efficiency is 86.27% at [O3]/[NO]=0.9.
