摘要/Abstract

摘要： 对于固定污染源烟气中PM_2.5测试方法,目前国内尚未出台相应标准,燃煤电厂烟气中PM_2.5测试技术是目前国内研究的热点,尤其是湿式电除尘器（WESP）后这种低浓度、高湿度烟气环境条件下PM_2.5的测试是目前国内的工程测试难题。利用ELPI对国内首台新建“超低排放”燃煤机组配套WESP前后PM_2.5进行测试研究,采用高温一级稀释方案,并将采样枪和旋风加热保温,有效避免了水滴对测试结果的影响,测试结果可信度较高,得出WESP对PM_2.5的脱除效率为78.77%。

Abstract: So far there is no corresponding standard released for measuring PM_2.5 in the flue gas from regular emission sources yet in our country. However, the testing technology for PM_2.5 emissions from coal-fired power plants still remains a hot topic in the current research. Especially it is difficult to perform the post-WESP PM_2.5 testing under low concentration and high humidity gas environment in current domestic engineering applications. In this paper, the testing study on PM_2.5 emissions from the WESP inlet and outlet of the first new “ultra-clean emission” coal-fired unit is conducted. By using high temperature dilute solution, the sampling gun and cyclone heat insulation, the influences of water droplets on the testing results are effectively avoided. Therefore, the results are of high credibility. The testing shows that PM_2.5 removal efficiency by WESP can reach as much as 78.77%.
