摘要/Abstract

摘要： 基于50 000 m³/h实际烟气中试试验系统，采用常规采样枪+玻纤滤筒和一体化采样头+石英滤膜测定总尘，采用ELPI测定PM_2.5，采用自制的控制冷凝+异丙醇吸收系统测定SO₃，采用BDL型飞灰工况比电阻测试仪测定飞灰工况比电阻。试验结果表明，130℃、90℃、80℃时电除尘器出口烟尘浓度分别为11.7mg/m³、9.7 mg/m³、5.4 mg/m³，PM_2.5浓度分别为0.8 mg/m³、0.4 mg/m³、0.2 mg/m³，总尘及PM_2.5减排效果显著；电除尘器出口SO₃浓度分别为1.25 mg/m³、0.10 mg/m³、0.14 mg/m³，对应低低温电除尘系统的SO₃脱除效率分别为22.84%、96.15%、96.61%，低低温电除尘系统可脱除烟气中绝大部分SO₃；电除尘器入口飞灰工况比电阻分别为3.02×10¹³ Ω·cm、6.15×10¹² Ω·cm、5.24×10¹¹ Ω·cm。

Abstract: Based on the 50 000 m³/h actual flue gas pilot test system, the total particle matters (TSP) are measured by using the conventional sampling gun plus glass fiber filter tube together with the integrated sampling head plus quartz filter membrane. In addition, PM_2.5 is measured by ELPI while SO₃ is measured by the independent R&D SO₃ sampling system, and specific resistance of fly ash is measured by using BDL type fly ash operating condition specific resistance tester. The test results show that the TSP concentration of ESP outlet are 11.6, 9.0 and 5.4 mg/m³ at the temperature of 130℃, 90℃, 80℃ respectively and the concentration of PM_2.5 are 0.8, 0.4 and 0.2 mg/m³, such that significant emission reduction of TSP and PM_2.5 is observed. The SO₃ concentration of ESP outlet are 1.25, 0.10 and 0.14 mg/m³, respectively, with the corresponding removal efficiency of the ESP system as 22.84%, 96.15% and 96.61% respectively, which means the low-low temperature ESP system is capable of removing the majority of SO₃ from flue gas. The ash condition resistivity of ESP inlet are 3.02×10¹³, 6.15×10¹² and 5.24×10¹¹ Ω·cm respectively.

Key words: coal-fired power plant, low-low temperature electrostatic precipitator, TSP, PM_2.5, SO₃, ash condition resistivity
