脉冲电晕脱硫脱硝反应器电极配置研究

从放电极配置的角度研究了脉冲电晕法烟气脱硫脱硝的关键技术之一能量注入问题。在线板型反应器上实验得到以下主要结果：（１）脉冲成形电容决定了高压纳秒脉冲宽度，放电极邻距在一定范围内的变化对脉冲宽度及脉冲上升前沿的影响可以忽视。（２）放电极邻距在保证不产生火花放电的情况下可以加到最密；这样脉冲成形电容的值可调整范围大，可以通过调整脉冲宽度达到多注入反应器能量的目的。（３）放电极密的时间，同其他邻距形式对

Research on electrode configuration in pulsed corona reactor for SO 2 and NO 2 removal

? The paper researches into the electrode configuration in line plane pulsed corona reactor. The main results are as follows:(1)High voltage nanoseconds pulse duration is decided by pulse forming capacitor. The changes of adjacent distance between discharge electrode have no effective influence on pulse duration and rise time. (2)The adjacent distance can be adjusted to the nearest one before breakdown. In this case, the value of pulse forming capacitor can be increased and the inject energy can be enhanced. (3) When the adjacent distance is adjusted to the nearest one (in this experiment it is 50 mm), the plasma channel in reactor is more homogeneous than others. This will be beneficial to SO 2 and NO 2 removal.
