燃煤烟尘细颗粒物排放控制技术及其研究现状

Research Status of Emission Control Technology of Fine Particulate in Coal Combustion

阐述了我国燃煤污染物的排放现状,并指出细颗粒物的脱除是亟待解决的重要问题。综述了国内外燃煤烟尘控制技术的研究进展,介绍了各种烟尘控制技术的原理、特点及其研究情况。结果表明,低低温电除尘技术、团聚技术及协同脱除技术已成为细颗粒物排放控制技术的热点,具有良好的应用前景。此外,分析并指出了除尘技术面临的难点和发展方向,为实现烟气中细颗粒物的脱除、达到超低排放标准提供了参考和借鉴。

This paper described the emission situation of pollutants from coal combustion in China,and it was pointed out that the removal technology of fine particulate matter was an important goal to be solved urgently.The research progress of soot control technology for coal burning at home and abroad was reviewed,and the principle,characteristics and research progress of the smoke and dust control technology were introduced.The results show that low-low temperature electric dust removal technology,agglomeration technology and synergistic removal technology have become the hot spots of fine particulate emission control technology and have a good application prospect.In addition,the analysis points out the difficulties faced by each part and the development direction,and provides reference for the removal of fine particulate matter from smoke and dust to meet the requirement of ultra-low emission standard.
