摘要
中国二氧化硫和氮氧化物的排放所引起的污染越来越严重,国家治理大气污染的力度逐步加大。现阶段单独脱硫脱硝的技术已经很成熟,考虑到经济高效的问题,烟气同时脱硫脱硝技术是当前烟气净化技术研究的热点之一。研究开发经济、高效、简单的烟气脱硫脱硝一体化技术十分必要和紧迫。本文介绍了几种典型烟气同时脱硫脱硝技术原理及其研究现状,分析了其原理及优缺点,对几种工艺进行了技术和经济分析。最后对脱硫脱硝一体化技术的发展前景作了展望。
The pollution caused by sulfur dioxide and nitrogen in our country is becoming more and more pressing. The inten-sity of national control of air pollution has gradually increased. Simultaneous desulfurization and denitrification technique is the de-veloping trend and hotspot for flue gas purification in China. Hence it is quite necessary and urgent to develop a new economical, efficient and simple way to carry it out. In this paper, principles and present situations are introduced of several typical techniques of simultaneous desulfurization and denitrification for coal-fired power plant flue gas. The main advantages and disadvantages are discussed, and technical and economic analyses are presented. In the end, the development prospect of the integrated technology of desulfurization and denitrification is prospected.
