| 摘 要： | 燃煤烟气中汞污染的控制是目前重要的环保课题之一,燃煤电厂利用现有的脱硝、脱硫、除尘设备去除汞,文章分析燃煤电厂烟气净化设备超低排放改造后汞的排放水平,说明现有废气处理设施超低排放改造,既能有效降低烟尘、二氧化硫、氮氧化物排放浓度,也有利于汞的去除,燃煤机组超低排放改造后汞的排放浓度远低于现行0.03 mg/m3的限值;通过分析燃煤电厂现有烟气净化设备对汞的协同去除效果和脱除汞的原理,提出了未来燃煤烟气汞污染控制措施的建议.

| Abstract: | Mercury pollution in coal-fired flue gas is one of the most important environmental issues. Mercury was removed in coal-fired power plants by using the existing denitration and desulfurization and dedusting. Mercury emission level was ana-lyzed after the ultra-low emission transformation of flue gas purification equipment in coal-fired power plants. The existing gas processing facilities could not only effectively reduce soot and sulfur dioxide and the concentration of nitrogen oxide emissions, but also suitable to the removal of mercury. Mercury emission concentration was far lower than the current 0. 03 mg/m3 limit value af-ter ultra-low emission transformation of coal-fired units. Based on mechanism of mercury synergy removal in existing flue gas purification equipment of coal-fired power plant, future coal-fired flue gas mercury pollution control measures were proposed. |
