Abstract
Ozone generation of micro plasma is investigated which is occurred with a pair of electrodes covered with dielectric barrier. The discharge gap of micro plasma is in the order of micro meters, which is very small compared to other discharge methods. Since the discharge gap is very narrow, non-thermal plasma is occurred around 1 kV, which also produces high electric field between the electrodes. By using micro plasma, pollutant gas control is possible with a very small power source and system. In this paper, electrical characteristics of micro plasma, practical discharge power, and the effect of number of electrodes are experimentally investigated. Also, treatment of low concentration of hazardous gases, such as cigarette smoke, nitric oxide is carried out by using micro plasma. Byproducts are confirmed by FT-IR and Fragrance & Flavor Analyzer.
