摘　　要：通过单组分有机酸添加剂的筛选、多组分有机酸添加剂组合优化和脱硫效率验证实验，最后优选出脱硫效果佳、对运行参数具有良好适应性和稳定性的高效复配脱硫添加剂。结果表明，当进口 SO2浓度为4500 mg/m 3时，复配添加剂可使系统脱硫效率达99％以上，比相同条件下脱硫效果最好的单组分添加剂提高0．4％～0．7％，比无添加剂时提高5％～8％。Based on the single-component organic acid screening step, the combinatorial optimization of multi -compo-nent organic acids and the SO 2 removal efficiency validation experiment , a composite additive was finally selected which has high SO2 removal efficiency and good adaptability and stability for the various operating conditions of WFGD sys -tem.The experimental results indicated when inlet SO 2 concentration was 4500 mg/m 3 , the SO2 removal efficiency was over 99% with the use of compound additive , which was 0.4% ~0.7% and 5% ~8% higher than the case of with the use of single-component additive and without additive , respectively.
