改性活性焦材料的制备方法及在烟气脱硫工程中的应用
|
摘要
活性焦烟气脱硫是一种目前较为先进的干法脱硫技术,它克服了传统的石灰石/石膏湿法脱硫技术存在的二次污染严重、耗水量大等缺点,同时又可以脱除多种污染物以及回收硫资源,对于我国煤炭资源丰富而水资源极度匮乏的西部地区有非常好的适用性。文章主要在总结概括了一些国内外相关文献的基础上介绍了一种用于烟气脱硫的环境合成材料,即活性焦。同时介绍了改性活性焦材料的制备方法以及在烟气脱硫工程中的应用。
Activated coke flue gas desulfurization is a relatively advanced dry process desulphurization technology at present, it overcomes the traditional limestone/gypsum wet desulfuration technology of secondary pollution, high water consumption, such as faults, can be removed at the same time a variety of pollutants and the recovery of sulfur resources, for my country is rich in coal resources and water resources are scarce in the western region has a very good applicability.In this paper, a kind of environmental synthetic material for ?ue gas desulfurization(FGD), namely active coke, is introduced on the basis of summarizing some related literatures at home and abroad.The preparation method of modi?ed active coke and its application in flue gas desulfurization project are also introduced.
