pH值对湿式石灰石烟气脱硫传质反应特性的影响

Effects of pH value on SO_2 removal and mass transfer performance in wet limestone FGD

在处理烟气量为1500m3/h的实验室试验装置上,进行了非稳态闭式循环脱硫试验,测定了脱硫率和吸收液pH值随时间的变化,分析了湿式石灰石烟气脱硫工艺中pH值对塔内传质反应的影响。

A set of wet limestone FGD facility with flue gas treatment of 1 500 m3/h was constructed. Unstable closed-circulated desulfurization test was conducted to investigate the effect of pH value on SO2 removal efficiency and mass transfer coefficient.
