In order to improve the concentration and output of ozone produced by dielectric barrier discharge, the characteristics of ozone produced by dielectric barrier discharge under different square wave pulse modes are studied in this study. The discharge characteristics of the system are analyzed, the discharge power of the system is calculated, and the concentration and output of ozone produced under different polarity, frequency and pulse width are studied. The results are analyzed and discussed. The results show that the ozone concentration is the highest (8.8 g·Nm-3) when positive and negative square wave pulses are applied, while the ozone yield is the highest (55 g·kWh-1) when positive square wave pulses are applied. With the increase of the frequency, the ozone concentration and production show a trend of first increasing and then decreasing. When the discharge frequency is 1 kHz, the ozone concentration is the highest, and when the discharge frequency is 1.5 kHz, the ozone production is the highest. Under the condition that other parameters are fixed, the ozone concentration increases slowly with the increase of pulse width, and the output of ozone basically remains unchanged.

Key words: dielectric barrier discharge, low temperature plasma, square wave pulse, different pulse modes, discharge characteristics, accumulated charge, ozone concentration, ozone yield
