湿式石灰石-石膏烟气脱硫系统的工艺控制

Process Control of Wet Limestone-gypsum Flue Gas Desulfurization System

通过实践提出湿法脱硫系统运行时工艺参数的优化值,重点讨论了浆液pH、石膏相对过饱和度的控制,以实例说明烟气负荷变化时设备运行方式的改变和参数的调整手段。

The optimum running values of wet limestone-gypsum flue gas desulfurization (FGD) system were proposed via practical experience, with focus on pH value of the slurry and relative supersaturation of gypsum crystallization. An example was given to illustrate how to change running mode of equipment and adjust process parameters with alteration in flue gas load.
