Effect of the Change in Electrode Construction for the Improvement of Ozone Characteristic of a Superposed Discharge Type Ozonizer

다국어 초록 (Multilingual Abstract)

In this paper a new discharge type ozonizer comprising the superpose operation of silent and surface discharge is presented. The ozonizer consists of two concentric glass tubes with three types of discharge electrodes : the external electrode(EE), the internal electrode(IE) and the central electrode(CE). By varying the structure of IE and materials of CE, we analyzed the characteristics of ozone related different parameters including O<SUB>3con</SUB>, O<SUB>3g</SUB>, and O<SUB>3Y</SUB>. Using Cu made CE it was found that O<SUB>3con</SUB> is higher with Cu tape than that with Cu coil wound IE. At Q = 1[l/min] the values of O<SUB>3con</SUB> were found as 3000[ppm] with Cu tape wound IE and 1898[ppm] with Cu coil wound IE. Then using SUS wire made CE with Cu tape wound IE at Q=1[l/min] the maximum value of O<SUB>3con</SUB> was found as 5632[ppm]. It was observed that both O<SUB>3con</SUB> and O<SUB>3Y</SUB> are higher with SUS made CE than that with Cu made CE. The maximum values of O<SUB>3Y</SUB> were found as 79[g/kWh] with Cu made CE and 170[g/kWh] with SUS wire made CE.
