An Experimental Study of Co-Axial Dielectric Barrier Discharge for Ozone Generation

Abstract

In this research work, co-axial cylindrical dielectric barrier discharge (CCDBD) system has been used as a ozone generator for ozone production with air as a working gas. The breakdown of air was generated inside the reactor by using low line frequency of 50 Hz and high AC voltage power supply system. The variation of air flow rate (Q) was taken from 10 to 16 l/min in this experiment. The O3 concentration denoted by C(O3) decreases with increasing the rate of flow of air at fixed discharge time and applied voltage. When discharge time (t) increases, C(O3) increases at fixed applied voltage. C(O3) also increases with increasing applied voltage (V) for constant discharge time. If the gap space between the electrodes increases then C(O3) increases. We have used glass tube reactor for this work having internal diameter of 18 mm and copper, brass and iron electrodes of diameter 8 mm. It was estimated that C(O3) found higher for copper electrode than both brass and iron electrode for certain discharge time, applied voltage and reactor diameter.

“…Ozone generated during the plasma discharge is directly affecting the microorganism which is responsible for destroying pathogens in the treated samples. is result is corelated with the result presented by Dyas et al [29][30][31].…”

Thin Film Deposition by Atmospheric Pressure Dielectric Barrier Discharges Containing Eugenol: Discharge and Coating Characterizations

“…Atmospheric dielectric barrier discharge (DBD) plasmas have drawn much attention due to low experimental cost, easy handling, and having no need for expensive vacuum systems [ 1 , 2 , 3 ]. DBD plasmas are the best choice for a variety of industrial applications, including large scale ozone generation, odor removal, and material processing [ 4 , 5 ]. In addition, the potential of non-thermal DBD plasma systems for various medical and biological applications including wound healing, tissue regeneration, blood coagulation, tooth bleaching, and cancer treatment has been demonstrated [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ].…”
