Positive pressure film air separation oxygen-enriched calcination application system for cement clinker production line
The invention discloses a positive pressure film air separation oxygen-enriched calcination application system for a cement clinker production line, the system adopts a positive pressure film air separation technology to generate oxygen-enriched gas and nitrogen-enriched gas, the oxygen-enriched gas is used for calcining clinker of a cement rotary kiln, and the nitrogen-enriched gas is recycled in a compressed air pipeline system of a cement production line system; the system comprises a positive pressure membrane nitrogen-oxygen separation assembly integration unit, an air compressor air supplement unit, a source gas treatment unit, an oxygen collection and utilization unit and a nitrogen collection and utilization unit. Through oxygen-enriched calcination, the combustion efficiency of pulverized coal can be improved, unit coal consumption of clinker is reduced, the operation condition of the cement kiln is stabilized, the yield of the cement kiln is improved, and emission of waste gas is reduced; meanwhile, compressed air used in a cement production line is utilized, so that the installed energy of an oxygen generation system is greatly reduced, investment is saved, waste of air is reduced due to recycling of nitrogen, and the oxygen generation cost is reduced.
本发明公开了一种用于水泥熟料生产线的正压膜空分富氧煅烧应用系统，该系统采用正压膜空分技术产生富氧气体和富氮气体，富氧气体用于水泥回转窑熟料的煅烧，富氮气体回收利用于水泥生产线系统的压缩空气管道系统中；该系统包括正压膜氮氧分离组件集成单元、空压机补风单元、源气处理单元、氧气收集利用单元和氮气收集利用单元。本发明通过富氧煅烧可以提高煤粉燃烧的效率，降低熟料单位煤耗，稳定水泥窑的运行状况，提高水泥窑产量，减少废气的排放；同时利用水泥生产线在用的压缩空气极大地降低了制氧系统的装机能量，节约了投资，氮气的回收再利用减少了空气的浪费，降低了制氧成本。
