氨与脉冲电晕等离子体脱除SO2的协同效应
Synergic effect on SO 2 removal by pulsed corona with ammonia
【摘要】 为了揭示氨与等离子体脱除SO2的协同效应,对比了脉冲电晕等离子体在氨气注入前后SO2脱除率的变化。实验结果表明,脉冲电晕等离子体单独作用时,SO2脱除率仅为9%~15%,而氨与脉冲电晕等离子体共同作用时,SO2脱除率可达90%以上(f=1.0).并从化学热力学角度探讨了氨与脉冲电晕的协同效应能显著提高SO2脱除率的原因,还考察了氧含量、温度对协同效应的影响
【Abstract】 Under pulse corona discharge,SO 2 removal efficiencies in the presence and absence of ammonia were compared.Experimental results showed the SO 2removal efficiency of 9%~15% only by pulse corona,but higher than 90% by pulse corona with ammonia.Based upon chemical thermodynamics,synergic effect on SO 2 removal by pulse corona with ammonia was discussed.In addition,the influences of oxygen content and temperature on synergic effect were also examined.
