基于中试平台的低低温电除尘器深度试验研究
The In-Depth Experimental Study on the Low Low-Temperature Electrostatic Precipitator Based on Pilot Platform
摘要
Abstract
Based on the 50000 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, PM2.5 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 PM2.5 are 0.8, 0.4 and 0.2 mg/m3, such that significant emission reduction of TSP and PM2.5 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.关键词
