摘　　要：以某发电厂330 MW机组石灰石-石膏湿法烟气脱硫系统新改造完成的串联吸收塔为研究对象,在满负荷工况下,针对不同入口SO_2浓度,试验研究了串联吸收塔浆液pH值、吸收塔液位、浆液循环泵分级控制对脱硫效率、SO_2排放特性以及脱硫能耗的影响。通过试验得出了满负荷工况下不同入口SO_2浓度区间时的最佳系统运行控制方式,为串联吸收塔脱硫系统的实际优化运行控制提供了依据和参考。The influence of Series -connected absorption tower slurry pH value,tower slurry level and hierarchical control to desulfurization efficiency, SO2 emission characteristics and energy consumption were researched for different inlet SO2 concentration in full load condition on series -connected absorption tower of limestone -gypsum wet flue gas desulfurization system which transformed completion recently. It is concluded that the best way to system operation control mode under different inlet SO2 concentration range in full load condition, which provided a basis and reference to the actual optimal operation control on series -connected absorption tower.
