Abstract

This study developed an ozone generator of a double co-axial cylindrical dielectric barrier discharge system with air, argon, and oxygen as the working gases. The discharge was produced by using a high voltage power supply of 0 - 18 kV and a line frequency of 50 Hz. The flow rate of air, argon, and oxygen was varied from 1 to 6 L/min. A comparison of O₃ generation in air, argon, and oxygen using brass as a central electrode was conducted and it was found that O₃ concentration was higher in the case of oxygen than in the air and in argon gases environment for given fixed discharge time, applied voltage, and diameter of the brass electrode. This study revealed that the concentration of ozone increased along with the increase in the applied voltage for constant discharge time and gas flow rate. The O₃ concentration also increased with the increase in the discharge time at fixed applied voltage and gas flow rate; however, the concentration decreased with the increase in the gas flow rate at fixed discharge time, applied voltage, and diameter of the electrode. A small reactor with a large inner electrode generated a high concentration of O₃. Yet, a reactor with a small diameter, there seemed to have an optimum inner electrode diameter. The glass tube reactor of the internal diameter of 18 mm and the brass electrode of diameter 8 mm were utilized in this study. The ozone concentration was higher for oxygen as feed gas than both in the air and in argon and the O₃ concentration was also higher in the air than in argon at fixed discharge time, applied voltage, and diameter of ozone generator.

HIGHLIGHTS

Ozone concentration increases with increasing applied voltage and discharge time but concentration decreases with increasing gas flow rates
Low cost ozone can be produced in DBD reactor at atmospheric pressure
Oxygen can be used as feed gas to generate high concentration of ozone than other gases inside DBD generator
Optimization of central electrode diameter and gap space inside DBD reactor can help to increase ozone concentration, yield, and efficiency
Proper choice of central high voltage electrode also can play the important role for the generation of ozone in DBD chamber
