| 摘 要： | 对若干超低排放项目进行汞的多点同步测试,分析不同技术路线下的汞排放及分布特征,研究发现：湿法脱硫对汞的脱除效率为22.2%~80.35%,湿式电除尘器对汞的脱除效率为0%~71.4%;湿法脱硫对汞的脱除效率与脱硫系统入口汞形态分布及负荷、气液传质强度有关;湿式电除尘器在汞入口浓度较低时,脱汞效果不明显。

| Abstract: | The test on mercury emission and distribution is carried out synchronously at multi-points in some ultra-low pollutants emission power plants. It is discovered that the mercury removal efficiency by WFGD is about 22.2%~80.35% and that by WESP is about 0%~71.4%. The mercury removal efficiency by WFGD is correlative to the mercury morphology at the entrance of WFGD, the unit load and the gas-liquid mass. WESP shows limit effect on the mercury capture when the mercury concentration at the entrance of WESP is low. |
