摘　　要：文章对动车组风源净化系统进行了优化设计,介绍了优化后风源净化系统的组成,并分别介绍除水、除油、除尘性能的优化设计方法。除水性能优化设计中,介绍了无热再生吸附式空气干燥器干燥、再生、均压的工作流程。通过理论分析,研究了进入空气干燥器压缩空气的温度与压力、空气干燥器再生耗气量和干燥时空气线速度对空气干燥器干燥能力的影响。经分析可知,增加空气压缩机到空气干燥器间的管路长度、提高风源系统最小压力阀设定值、在空气干燥器前设置除油装置等方法,可有效提升空气干燥器的干燥性能。同时介绍了压缩空气除油、除尘装置的设计。经优化,可保证动车组压缩空气的水、油、尘含量均达到运用要求。This paper optimizes the design of the air source purification system for EMUs,introduces the composition of the optimized air source purification system,and describes the optimization design methods of water removal,oil removal and dust removal performance respectively.In the optimization design of water removal performance,the working flow of drying,regeneration and pressure equalization of heatless regeneration adsorption air dryer is introduced.Through theoretical analysis,the influence of the temperature and pressure of compressed air entering the air dryer,air consumption for regeneration of the air dryer and air line speed during drying on the drying capacity of the air dryer are studied.Through analysis,it can be concluded that increasing the length of the pipeline between the air compressor and the air dryer,increasing the minimum pressure valve setting value of the air source system,and setting an oil removal device in front of the air dryer can effectively improve the drying performance of the air dryer.In addition,the design of compressed air oil and dust removal device is introduced.After optimization,it can ensure that the content of water,oil and dust in compressed air of EMUs can meet the application requirements.
