摘　　要：基于喷淋塔内脱硫过程中的流体力学数学模型,描述了湿式石灰石/石膏烟气脱硫法的脱硫效率与入口烟气SO2浓度、喷淋浆液中SO2浓度、烟气量、循环浆液量、钙硫摩尔比以及脱硫塔结构(截面积、吸收区高度等)的定量关系,重点分析了喷淋塔内液气比、烟气流速、吸收液的流量、喷嘴雾化性能、浆液pH值和烟气温度等参数,并阐述了这些因素对脱硫效率的影响。Based on the hydromechanics model of the process in the spray scrubber of wet flue gas desulphurization（FGD）, this paper gives the relationship of desulphurization efficiency with the concentration of SO2 in the inlet gas and inlet circulating slurry, L/G, Ca/S and the structure, namely, cross area and height of absorbing area, and mainly analyzes the influences of some parameters on the desulphurization efficiency, such as liquid-to-gas ratios, flue gas speed, the concentration of the inlet slurry, spraying characters, slurry pH values, temperature and so on.
