摘　　要：35000 m3/h空分设备氮水预冷系统采用密闭式循环水系统,但由于采用了不饱和补充水,使循环水水质的pH值降低、铁离子含量增高。通过采取提高循环水的饱和性和碱度、更换输水管路材质、清除铁锈等措施,彻底解决了问题。In the nitrogen-water pre-cooling system of 35000 m^3/h system is an enclosed circulation water system. Use of unsaturated and increase of iron ion concentration of the circulation water increasing saturation and alkaline of the circulation water, removing rust. air separation plant, the circulation water replenishing water results in decrease of pH and the said problem is completely solved through replacing material for water conveyance pipelines, and removing rust.
