摘要: 凝结水精处理系统离子交换树脂受到油污染后通常出现抱团、树脂漂浮和混床制水量下降等现象,给机组运行带来极大安全隐患。针对某电厂出现的凝结水精处理系统树脂油污染问题,通过对离子交换树脂的性能及污染状况进行分析,研究出经济可行的复苏方法。工程实践表明,某电厂油污染树脂采用该复苏方法进行处理后,树脂无抱团、悬浮现象,混床阴阳树脂分离效果良好,投运后出水水质满足GB/T 12145—2008《火力发电机组及蒸汽动力设备水汽质量》的要求,且恢复至未受污染时的水平。

Abstract: Generally, resin particle aggregation, resin floating and the reduction of cycling water production often occur when the ion exchange resin is contaminated by the oil in the condensate polishing system, which endangers the safe operation of the units. In this paper, aiming at these problems, through the analysis of the performance and status of the contaminated resin, the economic and feasible recovery method is developed. The practice shows that no aggregation or floating is observed in the oil contaminated resin after the treatment with the new recovery method. The resin separation is effective and the water quality is recovered to the pre-contaminated level, meeting GB/T 12145-2008 requirements.
