国内燃煤电厂污染物控制装置的脱汞特性

Mercury removal characteristics of domestic coal-fired power plant pollutant control device

选择国内3个典型的燃煤电厂,通过煤和烟气中的汞平衡分析,了解电厂的汞污染程度。评价了现有的脱硝、袋式除尘、静电除尘及湿法脱硫等设备对各种形态汞的脱除能力,为制定相应的汞污染控制措施提供理论依据。

Three typical domestic coal-fired power plants are chosen.Through mercury balance analysis in coal and flue gas,mercury pollution extend of power plants are understood,and the mercury removal ability of existing denitrification equipment,bag filter,electrostatic precipitator and wet desulfurization equipment are evaluated,which provides a theoretical basis for developing corresponding control measures of mercury pollution.
