乏风氧化及余热利用技术在山西潞安高河煤矿的应用

摘要

A large amount of coal mine ventilation air methane was directly exhausted into the atmosPhere,which not only intensified the greenhouse effect,but also caused the energy consumPtion,and if an aPProPriate technology was aPPlied to make full use of the mine ventilation air methane,huge benefits in energy saving and environmental Protection would be Produced. This PaPer described the mine ventilation air methane oxidation and the waste heat utilization technology in the home and abroad, emPhatically described the design and aPPlication of the Power generation Project with the mine ventilation methane oxidation in Lu’an Gaohe Mine in Shanxi Province,including the collecting and mixing system of the mine ventilation air methane,the safe delivery system of low-concentration gas,the oxidation system of the mine ventilation air methane,the utilization system of the waste heat and so on,and analyzed the significance of the successful construction of this Project.%大量煤矿乏风瓦斯的直接排空，在加剧温室效应的同时亦造成能源的浪费，而通过采用合适的技术对乏风瓦斯加以利用，将产生巨大的节能环保效益。介绍了国内外煤矿乏风瓦斯氧化及余热利用技术，重点介绍了山西潞安高河煤矿的乏风瓦斯氧化发电项目的设计及应用情况，包括乏风收集及掺混系统、低浓度瓦斯输送安全保障系统、乏风氧化系统、余热利用系统等，并分析了该项目建设成功的意义。
