摘　　要：控制燃煤硫减排的重要途径是对烟气中SO2进行脱除。综述了国内外现存的烟气脱硫技术,分别介绍了氧化法脱硫、化合法脱硫和复分解法脱硫的脱除原理,并对其优缺点进行了讨论。指出在选取脱硫技术时,应从技术可行性、安全性及经济性等多角度进行分析,要根据资源现状和技术用途合理选择脱除技术。未来对烟气燃煤脱硫技术仍具有很广泛的需求,需要开发新技术以应对排放标准不断提高的要求。Removing sulfur dioxide from flue gas is an important way to control the reduction of coal-fired sulfur.In this paper,the existing coal-fired flue gas desulfurization technologies were reviewed.The principles of oxidation desulfurization,chemical combination desulfurization and double decomposition desulfurization were introduced individually and their advantages and disadvantages were analyzed.In desulfurization technology selection,the analysis starts from the perspectives of technical feasibility,safety and economy,ends at appropriate removal technology,which follows current resource status and technical use.In the future,there will be a wide range of demands for coal-fired flue gas desulfurization technologies,and it is urgent to develop new technologies to satisfy the increasingly strict emission standards.
