摘要
煤的燃烧会释放大量的SO2和NOx,它们是导致酸雨和光化学烟雾等污染现象的主要污染物。燃煤电厂是我国煤消耗的主要场所,因此,控制硫、氮的排放应从燃煤电厂烟气脱硫脱硝的研究开始。对目前存在的几种烟气同时脱硫脱硝工艺进行了简要概述,主要包括等离子体法、氧化法、吸收及吸附法三类,并为脱硫脱硝工艺未来的发展提出了几点建议,以期为相关研究提供参考。
SO2 and NOx, products of the coal combustion, are the main wastes which lead to acid rain and photo-chemical smog. Coal-fired power plants are the principal places of China＇s coal consumption, therefore, study on desulfurization and denitrification of coal-fired power plant flue gas is the key to control sulfur and nitrogen emission. In this paper, several simultaneous denitrification and desulfiarization processes of flue gas were introduced, such as plasma method, oxidation method, and adsorption method. Finally, some suggestions on the future development of simultaneous desulfurization and denitrification process were put forward in order to provide reference for the related researches.
