摘　　要：针对燃煤烟气汞污染问题,本文综述了国内外燃煤烟气脱汞技术的研究进展,并将其划分为除尘同时脱汞技术、常规湿法脱硫同时脱汞技术和新型湿法脱硫同时脱汞技术3大类。详细阐述了这3类脱汞技术的技术特点及目前存在的问题。除尘同时脱汞技术较为成熟,但脱汞性能较低;常规湿法脱硫同时脱汞技术脱汞效率高,但脱除汞进入脱硫副产物中,增加环保隐患;新型湿法脱硫同时脱汞技术脱汞效率较高,脱汞吸收剂络合脱硫系统中汞,避免汞进入脱硫副产物中,且可对汞回收利用。可见,新型湿法脱硫同时脱汞技术是最具前景的燃煤烟气脱汞技术。This paper reviews the research progress about mercury removal technology domestic and overseas. The mercury removal technology includes simultaneous dedusting and mercury removal technology, simultaneous wet desulphurization and mercury removal technology and novel simultaneous wet desulphurization and mercury removal technology. This paper expounds the technical characteristics and existing problems about these mercury removal technologies in detail, and points out that the novel simultaneous wet desulphurization and mercury removal technology is the most promising technology for mercury removal.
