| 摘 要： | 对湿法脱硫石膏和干法脱硫石膏研究现状进行了总结和分析。湿法脱硫石膏可以代替天然石膏直接利用,研究比较成熟;干法脱硫石膏的应用受到亚硫酸钙含量的影响,附加值低,资源化利用受到限制,而目前的研究也仅停留在试验阶段,不能够规模化高附加值利用。目前急需加强对干法脱硫石膏的应用研究,针对性地根据脱硫石膏成分的变化拓展利用渠道,提高附加值,达到资源化利用的目的。

| Abstract: | Current situation of flue gas desulfurization（FGD） gypsum is summarized and analyzed. Wet FGD gypsum can replace natural gypsum in the utilization of cement, and the retarding effect of wet FGD gypsum is very well in cement; But the application of dry FGD gypsum is restricted by the effect of calcuim sulfite content, and its added value is low, it cannot be used widely, because the research of dry FGD gypsum only stays in theory. It is important to research how to apply dry FGD gypsum widely in practice,and expand fields of utilization according to the change in the composition, in order to improve the added value to recycle of purpose. |
