摘　　要：湿式石灰石石膏法烟气脱硫技术是当前运行最稳定,应用最广泛的烟气脱硫技术。随着SO2排放标准日益严格,原有脱硫设备难以达标,使用脱硫增效剂较之脱硫系统改造费用低、见效快。文章从加快CaCO3溶解、促进SO2吸收、平衡浆液pH、提高固硫效果,提高氧化速率、提高产物结晶速率、提高分散性方面分析了增效剂的提效降耗机理。此分析可为增效剂的开发及应用提供参考,带来环境效益和经济效益。Gypsum wet limestone FGD technology is currently running the most stable, the most widely used FGD technology. With increasingly stringent emission standards for SO2, the original standard desulfurization equipment is difficult to use than the desulfurization desulfurization system transformation synergist low cost, quick. This paper analyzes the efficiency improving and consumption reducting mechanism of synergist base on accelerating the dissolution of CaCO3, promoting SO2 absorption, balancing slurry pH, increasing the oxidation rate, improving product crystallization rate and improving dispersibility. The analysis provides for the development and application of synergist reference, bring environmental and economic benefits.
