摘要
随着我国环保政策的日益收紧,SO2的有效治理至关重要。综述了水泥行业典型的湿法、干法和半干法脱硫技术中的石灰石石膏法、双碱法、氨法脱硫、热生料喷注法、干反应剂喷注法、喷雾干燥法、循环流化床法等的原理和优缺点,提出我国未来烟气脱硫技术发展方向。
With the increasingly tightening of environmental protection policy in China,the control of SO2 emission is very crucial.In this paper,wet flue gas desulfurization technology,semi dry flue gas desulfurization technology and dry flue gas desulfurization technology are summarized,including limestone gypsum method,double alkali method,ammonia desulphurization method,hot raw material injection method,dry reaction agent injection method,spray drying method and circulating fluidized bed method.The future development of flue gas desulfurization technology in China is also prospected.
