Abstract

In this paper, the discharge image of NO particles wire-cylinder type electrode in the discharge reactor where AC dielectric barrier type corona discharge occurred and horizontal and vertical signal intensity at each flourescence emission during discharge and the horizontal and vertical signal strength of NO particles at flourescence emission wavelength band[236[nm], 247[nm]], were measured were measured by ICCD Camera. In addition discharge images and signal intensities in accordance with discharge time were measured to figure out the discharge mechanism. It was found that the strongest horizontal and vertical signal intensity of NO particles were observed at 247[nm] band, but no big difference in the horizontal and vertical signal intensity in accordance with discharge time was seen. In particular, the phenomenon image occuring inside the discharge reactor and wavelength ware able to be carried based on the measured data.

본 연구에서는 교류유전체장벽형 코로나방전을 이용하여 선대원통형 전극구조의 방전리액터내의 NO입자의 방전 Image와 형광방출파장대역[236[nm], 247[nm], 259[nm]에서의 수평방향과 수직방향의 신호강도를 ICCD카메라를 이용하여 측정하였다. 또한 방전메카니즘을 알기 위해서 방전진전시간에 따른 방전 Image와 신호강도 측정을 행하였다. NO입자의 수평과 수직방향의 신호강도는247[nm]대역에서 가장 큰 것을 확인 할 수 있었으며, 방전진전시간에 따른 수평과 수직방향의 신호강도는 큰 변화가 없었다. 특히 측정된 데이터로부터 반응장치 내부에서 일어나는 현상의 Image와 형광방출파장의 신호강도를 비교할 수 있었다.
