      超低排放下不同湿法脱硫技术脱除SO3效果测试与分析

      Test and Study on SO3 Removal Performance of Different Wet Flue Gas Desulfurization Technologies at Ultra-Low Pollutants Emission

      摘要:
      对5个实现超低排放电厂的炯气中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 causedby 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.
