垃圾焚烧烟气汞的治理技术与评价
Control Technologies and Evaluation of Mercury in Flue Gas of Waste Incineration
Abstract
介绍了当前垃圾焚烧烟气中汞形态分布,对利用现有设备脱汞、nA2S喷射、吸附剂捕集等方法在烟气脱汞运用中的优缺点进行分析,建立实验室规模的活性炭吸附-脱附系统,对比氮气氛围不同活性炭对气态汞的吸附性能,以更好地控制垃圾焚烧烟气中气态汞的排放行为。 The mercury speciation distribution in flue gas of waste incineration was introduced.The advantages and disadvantages of different ways on mercury controlling were analyzed,including using the existing equipment,Na2S injection and sorbent trapping.A laboratory-scale activated carbon adsorption-desorption system was developed,and the adsorption properties of different activated carbon in nitrogen atmosphere were compared to control gaseous mercury in flue gas of waste incineration.
