摘要
针对脉冲电压Up沿放电线传播发生流光电晕放电,脉冲能量注入反应器内产生活性自由基进行烟气脱硫脱硝过程中,沿线Up波形的变形及脉冲能量的衰减会影响活性自由基产生的问题,为给设计工业应用反应器的几何尺寸提供依据,研究了Up及脉冲能量沿放电线变形、衰减的特性,且研究了电压、脉冲成形电容Cp、线径d及线长l等因素对能量传输、衰减的影响。实验结果表明脉冲电压沿放电线传输时,电压波形发生衰减,随着传输距离的增大,电压波形变形严重;电压、Cp、d和l对能量衰减有一定的影响,增大电压、Cp和d,沿线脉冲能量的衰减速度增大;l越短,能量衰减越快。实验得出最佳l≤10 m。
In this paper the characteristics of pulse voltage the discharge wire in a wire-plate pulsed corona discharge cost and improving the removal efficiency of SO2 and NOx waveform distortion, and pulse energy attenuation along reactor have been investigated for decreasing the energy from flue gas. The influences of voltage, pulse-forming capacitance, wire diameter and length on pulse energy transmission and attenuation have also been studied. The results show that the pulse voltage produces distortion. Pulse length and front rise time increases with increase of transmission distance. The peak of pulse voltage decreases sharply at first, and then decreases slowly, but at last it increases at the tail of the discharge wire. Increasing voltage, pulse-forming capacitance and discharge wire diameter can improve the attenuation rate of pulse energy. The length of discharge wire has great influences on energy attenuation, and energy attenuation becomes quicker as discharge wire is shorter. The results reveal that the optimal discharge wire length should be chosen less than 10m in practical design for improving the efficiency energy of discharge wire in reactor.
