摘要
随着环保意识的增强,燃煤电厂汞污染越来越受到人们的关注,对燃煤电厂烟气汞污染的控制也逐渐成为热点。介绍了燃煤电厂烟气中汞的排放形态及特性,分析了燃煤电厂烟气汞形态转化的影响因素,综述了有关燃煤电厂烟气中汞污染控制技术及研究进展,讨论了燃烧前脱汞、燃烧中脱汞和燃烧后脱汞技术,特别分析了利用现有烟气脱硫设备吸收法脱汞、吸附法脱汞、催化氧化脱汞的技术,并对燃煤电厂烟气脱汞技术的前景进行了展望,提出结合现有烟气净化设备同时脱汞的设想。
Mercury pollution control from coal - fired power plants receives people＇s attention as the awareness of environmen- tal protection increases. The morphology and characteristics of mercury emission are introduced. The factors of mercury transfor- mation are analyzed. Mercury removal technology and its research progress are summarized. Pre - combustion mercury, combus- tion and post - combustion mercury removal technology are discussed. Absorption demercuration technology using existing flue gas desulfurization equipment, adsorption demercuration technology, catalytic oxidation technology are particularly analyzed. The out- look of the technology of coal - fired plant flue gas demercuration are put forward, as well as the idea of the combining with the ex- isting flue gas purification equipment to remove mercury.
