摘　　要：结合国内钙法烟气脱硫技术的特点,阐述2种脱硫剂的来源和反应机理,并从脱硫剂的共性、脱硫产品的多样性及经济性、节约硫资源和脱磷石膏的环保性等5方面,分析使用磷矿石代替石灰石作为钙法烟气脱硫剂以脱除烟气中SO2气体,并生产湿法磷酸的可行性。Based on the characteristics of domestic Calciumbased flue gas desulfurization technology,the origin and reaction mechanism of the two kinds of desulfurizers were discussed,and the feasibility of using phosphate rock instead of limestone as calcium-based flue gas desulfurizer to remove SO_2 gas from flue gas and producing wet process phosphoric acid is analyzed from the following five aspects:the commonality of desulfurizer,the diversity and economy of desulfurization products,the saving of sulfur resources and the environmental protection of dephosphorized gypsum.
