中文摘要	在中温(400℃~800℃)干法循环流化床烟气脱硫工艺中,由于反应产物CaSO4的比摩尔容积大于脱硫剂CaO的比摩尔容积,进而使得SO2气体在脱硫剂颗粒内的扩散变得非常困难,从而影响了脱硫反应的进行和脱硫剂的利用率。为了提高钙利用率,采用中高温(800℃)硫化、低温(150℃)蒸汽活化的方法来处理乏脱硫剂。在文中提出了移动床式蒸汽活化器和流动床式蒸汽活化器两种方案,并进行了计算和分析。; In the technology of Medium Temperature Dry Regime Circulating Fluidized Bed Flue Gas Desulfurization(CFBFGD),since the specific mole volume of reactive product CaSO_4 is much greater than that of CaO,it is difficult for SO_2 to diffuse into the sorbent particles,so that the process of the desulfurization reaction and the usage of the sorbent are influenced.In order to improve the sorbent's usage,the used sorbent is reacted at high temperature and activated at low temperature by steam.Two schemes were put forward in the paper:movable bed type steam activation device and fluidized bed type steam activation device,and calculation and analysis were conducted respectively.
