烟道气脱硫脱硝一体化技术进展＊

烟道气中SO2、NOx往往同时存在,但是实际中脱SO2、脱NOx两个过程相互影响,妨碍了两种污染物质的脱除。联合脱硫脱硝技术是烟气治理的发展方向。系统介绍了利用催化剂、类水滑石复合氧化物、活性炭、固体废物、电子束、脉冲电晕等脱硫脱硝的一体化技术,分析了其脱除过程及相关反应原理。比较探讨了各种方法的特点、应用情况,并对各类技术的应用前景进行了展望。

Advance of Flu Gas Desulfurization & Denitrification Integrative Technique

SO2 and NOx were often found simultaneously in flue gas,but the desulfurization and denitrification of flue gas interacted with each other,which hold back the desulfurization and the denitrification. The integrative technique of desulfurization and denitrification were the developing direction of flu control including catalyst method,solid castoff method,active carbon method,solid rubbish method,electron beam method,pulse method and so on. The reaction process and principle were analyzed. The application characteristic and future of each method was also compared and discussed.
