摘要
通过文献调研分析了影响我国燃煤电厂除尘技术路线选择的主要问题,从煤质含硫量、粉尘比电阻、粉尘粒径分布三方面研究结果表明电除尘技术对我国煤种的适应性较差,无法满足严格的排放标准;另外,通过前人对比不同除尘方式协同脱汞效果和对下游设备保护作用的研究成果,结果表明袋式除尘器具有更好的协同脱汞作用,更高的除尘效率并赋予湿法脱硫设备长期可靠运行。
Through the literature research,some main problems of selecting dedusting technical paths in China’s coal-fired power plants were analyzed in this paper. The results show that ESP technology has poor adaptability to the coals in China from the sulfur content of coal,dust specific resistivity and dust particle size distribution. In addition,through the research results of the predecessors’ comparison of mercury removal and protection of wet desulphurization equipment,it has been found that bag filter has better efficiency of mercury removal; due to the higher dust removal efficiency,the wet desulphurization equipment would operate safely and reliably for a long time.
