| 摘 要： | 以发射光谱法为基础,检测了常压状态线-板式脉冲电晕放电过程OH自由基在反应器内的空间分布;研究了线电极直径,线线间距以及线板间距对生成OH自由基的影响;从而明确脉冲电晕放电反应器的性能。结果显示:OH自由基浓度沿线电极X轴方向逐渐降低,活化区域半径20mm左右,沿Y轴方向先升高后降低,活化区域半径大于30mm;线电极的直径小于2mm时,OH自由基的光谱强度基本不变,线电极直径继续增大,发射光谱强度随之迅速下降。线线间距逐渐增大,OH自由基的发射光谱强度随之增强。OH自由基的发射光谱强度随着线板间距的增大而降低。

| Abstract: | In order to get extensive knowledge of wire-to-plate pulsed corona discharge reactor,the influences of different diameters of wire electrode,different wire-to-plate and wire-to-wire spacing on OH radical generation were experimentally investigated under atmospheric pressure based on emission spectrum,and the spatial distribution of OH radicals in the electric field was also discussed in detail.The results showed that OH radicals decrease along the X-axis,and the activation radius is approximately 20 mm;show... |
