摘　　要：煤矿瓦斯发电时,瓦斯中的H_(2)S气体会对瓦斯输送管道、设备及瓦斯发电机组造成酸性腐蚀,需在瓦斯发电前将其脱除。简介了常用的三种脱硫方法及瓦斯发电装置对脱硫系统的要求,分析确定了煤矿瓦斯发电选用湿法脱硫技术。介绍了络合铁湿式氧化法脱硫的原理和工艺流程,基于某煤矿瓦斯发电站开展了络合铁湿式氧化脱硫系统设计,现场运行结果表明:脱硫后瓦斯中H_(2)S体积分数维持在190×10-6左右,达到设计要求;检验瓦斯发电机组,未发现因H_(2)S造成的腐蚀,发电机组运行良好。During coal mine gas power generation,H_(2)S gas in it caused acidic corrosion to gas transmission pipelines,equipment,and gas generator units.It was necessary to remove the H_(2)S from the gas before using it for power generation.Three commonly used desulfurization methods and the requirements of gas power generation unit for desulfurization system were introduced,and the wet desulfurization technology selected for coal mine gas power generation was determined by the analysis.The principle and process flow of chelated iron wet oxidation desulfurization were introduced.A chelated iron wet oxidation desulfurization system was designed based on a coal mine gas power station.The on-site operation results showed that the volume fraction of H_(2)S in the gas was kept at about 190×10-6 after the desulfurization,meeting the design requirements.During the inspection of the gas generator set,no corrosion caused by H_(2)S was found,and the generator set was operating well.
