脉冲流光放电反应器电极配置对脱硫效率的影响

The Influence of Electrode Configuration on SO_2 Removal Efficiency in a Pulsed Streamer Discharge Reactor

采用处理烟气量为200 Nm3／h的线-板式脉冲流光放电反应器进行了模拟烟气脱硫实验研究。在一定实 验条件下,研究了电压、脉冲成形电容及不同线-线间距与线-板间距的配置对反应器的脱硫效率及能量消耗的 影响．结果表明:随着电压、脉冲成形也容的增大,反应器脱硫效率升高,但反应器的能量消耗增大;在线-板 间距10 cm条件下,最佳线-线间距为6-10 cm时,反应器能量密度最大,脱硫效率最高,且能量消耗最低。在 最小能耗16．7 eV／mol下,脱硫效率达85％．

The effects of voltage, pulse-forming capacitance and electrode configuration on the SO2 removal efficiency and energy cost have been investigated in a wire-plate pulsed streamer discharge reactor with flow rate of 200Nm3/h. Increasing voltage and pulse-forming capacitance can increase the removal efficiency of SO2, but also increase energy cost. Under the optimal conditions of 6-10cm wire-to-wire spacing and 10cm wire-to-plate spacing, the highest removal efficiency of increases and more than 85 % and the lowest energy cost of 16.7 eV/mol sind obtained.
