| 中文摘要 |
| 采用多针-板式电极,在70 m3/h烟气流量范围内,研究了水蒸气浓度、烟气流量、电场强度等因素对不饱和水蒸气正直流电晕放电烟气脱硫率的影响以及水蒸气电晕放电对脉冲放电烟气脱硫率的提高.研究结果表明,实验范围内,按照NH3∶SO2摩尔比为2∶1添加NH3的条件下,增加水蒸气流量、增强电场强度、减少烟气流量,烟气脱硫率能提高10%,达到60%左右.同时,水蒸气电晕放电能使脉冲放电的烟气脱硫率提高5%左右,达到90%以上. |
| 英文摘要 |
| The influence of several factors on removal rate of SO2 from flue gas in unsaturated water vapor DC corona discharge was researched.Furthermore, the experiments of the removal rate of SO2 in pulsed discharge increased by water vapor DC corona discharge plasma were conducted.The experiment system is supplied with multi-nozzle-plate electrodes and the flow of simulated flue gas is under 70(m3/h).The results show that removal rate of SO2 can be improved by increasing the concentration of water vapor,intensity of electric field or decreasing flow of simulated flue gas.In unsaturated water vapor DC corona discharge,removal rate of SO2 can be improved by 10%,when NH3 is added as NH3 and SO2 is in a mole ratio of two to one,it can reach 60%.The removal rate of SO2 can be increased by 5% in pulsed corona discharge and reach above 90%. |
