摘要: 为较全面表征低低温电除尘系统(FGC+ESP)对SO₃减排特性，提出了一种低浓度SO3测试方法，即“2级控制冷凝+1级异丙醇吸收”采样法，可提高其测试数据的准确性。并基于此，测定中试平台低低温电除尘系统(ESP入口90℃)的SO₃脱除效率为96.15%。3个工程项目4组现场实测数据中，低低温电除尘系统对SO₃脱除效率在69.1%~96.6%，分析并验证了低低温工况条件下飞灰颗粒对SO₃的吸附、团聚机制。研究结果可为低低温电除尘技术的大规模推广应用及燃煤电厂SO₃减排提供借鉴。

Abstract：In order to fully characterize the emission reduction performance of SO₃ by low-low temperature electrostatic precipitator system (FGC+ESP), a method to test low-concentration SO₃was proposed in this paper, namely “two-stage controlled condensation + one-stage isopropanol absorption” sampling method, which can improve the accuracy of its test data. According to this method, in the pilot test, the SO₃removal efficiency of the low-low temperature electrostatic precipitator (LL-ESP) system (90 ℃ at ESP entrance) was 96.15%. In 4 groups of field measured data from 3 engineering projects, the SO₃removal efficiency of LL-ESP system was 69.1%-96.6%. The mechanism of SO₃ adsorption and agglomeration by fly ash particles under low-low temperature conditions was verified. The study results can provide reference for the large-scale promotion and application of LL-ESP technology and SO₃ emission reduction of coal-fired power plants.
