氨与脉冲电晕等离子体脱除SO_2的协同效应

Synergic effect on SO 2 removal by pulsed corona with ammonia

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。

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.
