摘要
燃煤烟气排放的大量气态污染物危害严重,分级治理系统庞大、投资昂贵。湿式脱硫法目前应用广泛,在此基础上加以改进开发同时脱硫脱硝脱汞技术具有必要性和可行性。扼要总结了国内外湿式氧化法在烟气中SO2、NO和Hg0脱除方面的研究概况,包括次氯酸盐氧化法、过硫酸氧化法、H2O2氧化法。介绍了各方法的研究现状、特点、存在问题等,为该方法实现更高效的烟气净化效率提供参考。
The gaseous pollutants exhausted from coal combustion have brought serious harm. The system is bulky and the cost is expensive when treated individually. From the basis of wet fuel gas desulphurization,which applies extensively in our country,there will be a great necessity and feasibility in developing the corresponding way of simultaneous removal in wet process. The paper mainly describes several typical oxidation processes for simultaneous removal of SO2,NO and Hg0 in wet process. It includes pypocholoride,persulfate and H2O2. Also,the research status and characteristics of each method are summarized. The existing problems are analyzed. More work need to be done in realizing higher purification efficiency.
