본 논문에서는 고농도$\cdot$고수율 오존발생기를 개발할 목적으로 망사형 내부전극과 무성방전의 중첩을 이용한 중첩방전형 오존발생기를 설계$\cdot$제작하였다. 중첩방전형 오존발생기는 방전공간에 3개의 전극(중심전극, 내부전극 및 외부전극)과 2개의 gap(중심전극과 내부전극 사이의 gap과 내부전극과 외부전극 사이의 gap)으로 구성되어있다. 중첩방전형 오존발생기의 중심전극을 공통접지하고 내부전극과 외부전극에 $180{[^\circ]}$의 위상차를 가진 역극성의 교류 고전압을 각각 인가하면 각각의 방전 gap에서 발생하는 무성방전이 중첩되면서 오존이 발생된다. 이때, 내부전극의 조밀도가 증가할수록 방전전극의 면적이 확대되고 방전공간의 전력밀도가 억제되어 오존생성특성이 상승하였다. 그 결과 최대 17,720[ppm], 5.4[g/h] 및 250[g/kwh]의 오존을 얻을 수 있었다.

A hybrid discharge type ozonizer, which is superposed silent and surface discharges, has been designed and manufactured to apply for Nitrogen Oxides(NO) gas removal. The ozonizer consists of three electrodes, and is classified three types of ozonizer by changing applied voltage. Investigation was carried out variance with the flow rate of supplied oxygen gas, discharge power and the sorts of superposed discharge type ozonizer. Moreover, $NO(1200[ppm])/N_2$ gas removal investigation was also conducted to apply for environment improvement field. Two kinds of NO gas removal investigations were conducted. It distinguishes the investigations into NO gas reaction method. According to these studies, maximum removal rate of 100[%] in NO gas was obtained, and 8334[ppm] and 3249[mg/h] of maximum ozone concentration and generation were also obtained respectively.

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 type 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 $O_{3con}$, $O_{3g}$, and $O_{3Y}$. Using Cu made CE it was found the O3con is higher with Cu tape than that with Cu coil wound IE. At Q = 1[l/ min] the values of O3con 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[ι/ min] the maximum value of O3con was found as 5632[ppm]. It was observed that both $O_{3con}$ and $O_{3y}$ are higher with SUS made CE than that with Cu made CE. The maximum values of $O_{3Y}$ were found as 79[g/kWh] with Cu made CE and 170[g/kWh] with SUS wire made CE.
