现有设备协同脱汞技术概述

介绍了燃煤电站汞的排放状况,并指出了汞危害性以及我国面临的脱汞压力,论述了烟气中汞存在形式以及影响其存在形式的因素.探讨了当前燃煤电站利用现有污染控制设备进行协同脱汞的研究进展,包括：燃烧器/反应器、选择性催化还原脱硝（SCR）、电除尘器（布袋除尘）（ESP/FF）、湿法烟气脱硫系统（WFGD）等设备.提出了脱汞吸附剂处理问题,并对今后烟气脱汞技术的研究趋势进行了展望.

Overview of existing equipment synergy to remove mercury technology

It introduces the mercury emissions in coal- fired power plants,and points out the dangers of mercury and China faces huge pressure to mercury removal. And the existence form of mercury in flue gas and the effects on its existing form factor are discussed. The plants use of existing pollution control equipment for collab- orative to the mercury removal research are described,including burner/reacftor,selective catalytic reduction, e- lectrostatic precipitator （bag dust removal） and wet flue gas desulfurization system,and other equipment. Final- ly, problem of how to deal with the adsorbent after the mercury removal is put forwanrd and the research tenden- cy of flue gas to the mercury removal technology in the future are forecasted.
