湿法烟气脱硫系统协同脱汞研究进展及优化措施

Research and Optimization Measures on Synergistic Mercury Removal by Wet Flue Gas desulfurization System

近年来,燃煤电厂的汞污染排放问题引起了广泛关注,湿法烟气脱硫(WFGD)系统在去除二氧化硫的同时,对烟气中的汞也有明显的脱除效果,被认为是最适合我国国情的烟气脱汞方法。本文对近年WFGD系统协同脱汞的研究进展进行了总结,并针对其在应用中所存在的问题提出优化措施,以进一步提高其协同脱汞效果。

In recent years, the mercury pollution problem of coal-fired power plant has drawn great attention. Wet flue gas desulfurization （WFGD） system has obvious removal effect of mercury in flue gas while removing sulfur dioxide, and it has considered to be tile most suitable flue gas demercuration method for China＇s national conditions. In this paper, the recent research progress of synergistic mercury removal by WFGD system are summarized, and to further improve the synergistic removal effect of mercury, some optimization measures are put forward to solve the problems existing in the application.
