| 摘 要： | 对5个实现超低排放电厂的烟气中SO3实测结果进行了分析,发现超低排放湿法脱硫技术脱除SO3性能明显不同于国内外有关研究结果,空塔、海水、单托盘、双托盘、旋汇耦合等湿法脱硫技术脱除SO3效率依次从低到高,存在较大差异,分析认为是气液传质强化等原因形成的,表明超低排放脱硫技术革新也带来了SO3脱除性能的进步。

| Abstract: | The SO3 test results of five power plants with ultra-low pollutants emission are analyzed, The analysis shows that the SO3 removal performance of the wet flue gas desulfurization(WFGD) technologies used in ultra-low pollutants emission is obviously different from that in the domestic and foreign relevant research results. The SO3 removal efficiency of the WFGD technologies, in the order of empty tower, seawater, single-pallet, double-pallet and rotating coupling, is quite different, which is from low to high. It is considered to be caused by the enhancement of gas-liquid mass transfer. The study indicates that the innovation of WFGD technologies for ultra-low pollutants emission has brought the progress of SO3 removal performance. |
