| 摘 要： | 采用pH-stat方法，用盐酸中的H^＋模拟代替SO2与水结合形成H2SO3产生的H^＋，研究了添加有机酸对石灰石溶解速率的影响。结果表明：有机酸浓度、溶液pH值、有机酸种类对石灰石溶解速率影响最大。添加一定质量的有机酸，可以大大提高进入脱硫塔的石灰石的粒度，降低磨矿能耗，并在此基础上提出了有机酸提高石灰石溶解速率的机理。

| Abstract: | Effects of organic acids on limestone dissolution rate were investigated by pH-stat method. The results show that concentration of organic acid, acidity of limestone slurry and the kind of organic acid are the main factors to increase limestone dissolution rate. Using high concentration of organic acid, the granular limestone can be used as a desulfurizing reagent. Thus, the energy of the pulverizing limestone can be reduced. Furthermore, organic acid promoting limestone dissolution mechanism is suggested. |
