燃煤烟气多污染物一体化控制技术研究进展

PROGRESS IN STUDY ON MULTI-POLLUTANT CONTROL TECHNOLOGY FOR COAL-FIRED FLUE GAS

燃煤烟气排放的污染物主要有烟尘、SO2、NOx、Hg及温室气体CO2等。为满足不断提高的环保要求及降低环保成本,国内外的研究开始转向在1个装置内同时脱除多种污染物。介绍近年来国内外烟气多污染物处理技术方面的试验研究,主要包括干式吸附法、脉冲电晕等离子体法、臭氧氧化法、湿法氧化法、循环还原法等。

The main pollutants of coal-fired flue gas are smoke dust,SO2,NOx,and Hg.In order to satisfy the unceasingly enhanced requirements for environment protection,and to decrease the cost in environment protection,the study at home and abroad has begun turn to remove simultaniously a variety of pollutants in one device.The test study in aspects of multi-pollutant treatment technologies for flue gas at home and abroad in recent years has been presented,including mainly the dry absorption method,the pulsed corona plasma method,the ozone oxidation method,the wet oxidation method,and teh cyclic reduction method etc..
