  • 摘要: 为了解电袋复合除尘器协同脱除燃煤烟气中的气态Hg、颗粒Hg和SO3的效果，在4个电厂选择4台采用电袋复合除尘器进行烟气除尘的燃煤机组，在电袋复合除尘器的进口和出口分别对烟气中的气态Hg、颗粒Hg和SO3浓度进行了实测，计算出电袋复合除尘器的协同脱除效率。结果表明：不同火电厂烟气中Hg的形态分布不同；在本实验工况条件下，电袋复合除尘器对总Hg的协同脱除效率为47.55%~93.88%，对气态Hg的协同脱除效率达18.80%~83.46%；电袋复合除尘器对SO3的协同脱除效率为74.31%~85.91%；由于SO3与气态Hg产生竞争吸附现象，导致电袋复合除尘器对气态Hg的协同脱除效率随入口处烟气中SO3浓度的提高而下降。
    Abstract: In order to understand the synergetic removal effect of gaseous Hg, particulate Hg and SO3 in flue gas from Electrostatic-Fabric Integrated Precipitator (EFIP), 4 coal-fired units equipped with EFIP were selected,and the concentrations of gaseous Hg, particulate Hg and SO3 in flue gas were measured at the inlets and outlets of EFIP, respectively. The synergetic removal efficiency of EFIP was calculated, showing that the flue gas from different power plants have varied partitioning of mercury. Under the experimental conditions, removal efficiency of total Hg by EFIP was 47.55% to 93.88%, while the removal of gaseous Hg was 18.80% to 83.46%, and removal efficiency of SO3 was 74.31% to 85.91%. There was a competitive adsorption between SO3 and gaseous Hg, and removal efficiency of gaseous Hg decreased with the increase of SO3 concentration in flue gas.
