Complex Characterization of Gliding Arc Discharge for Advance oxidation Processes

摘要

Advanced oxidation processes were originally developed for low-temperature water cleaning processes. They are based on production of high oxidative radicals like atomic oxygen or OH groups, which destroy various organic pollutants. Atmospheric plasma discharges belong to high-effective sources of oxidizing radicals. Among various methods of plasma production at atmospheric pressure, the gliding arc belongs to sources with high industrial potential because of its high efficiency and simple construction. For proper and quick employment and particular process optimization detailed knowledge of plasma source parameters is of great importance. We will present results of complex investigation of an gliding arc discharge and optimization of an gliding arc head construction for industrial applications. Using proper diagnostic techniques optimal working conditions were set for different applications. Examples of particular applications of the gliding arc will be given.
