摘要
高压窄脉冲流注电晕放电的非平衡等离子体脱硫脱硝是开发中先进的燃煤烟气净化技术.采用模拟烟气和自行研制的脉冲电源及反应器,研究脉冲电晕对SO_2、NO氧化脱除机理和规律.结果表明,正脉冲电晕将SO_2、NO氧化成相应的酸很有效,远优于负脉冲电晕;正脉冲电晕氧化SO_2、NO的能量利用率分别为64.3·SO_2/kwh和9.9g·NO/kwh;加入氨水能有效地改善脱硫脱硝效率和能量利用率;温度对SO_2、NO的电晕氧化有较大影响,从氧化脱除效率和能量利用率考虑,较低温度对SO_2、NO的电晕氧化有利.
De-SO2 and de-NOx from coal-burning flue gas by non-equilibrium plasma in high-voltage narrow pulsed streamer corona is an advanced technology under development. A research on the oxidation mechanism and laws of oxidation of SO2 and NO by pulse corona showed that positive pulse corona is far more efficient than negative pulse corona for oxidating SO2 and NO into their acidsj the energy yields of S02 and NO oxidation by positive pulse corona are 64.3gSO2/kwh and 9.9 gNO/kwh, respectively. Temperature has great influence on the corona oxidation of SO2, NO, in the terms of oxidating removal efficiency and energy yield, lower temperature is more favorable for corona oxidation of SO2 and NO.
