凝结水处理中汽轮机油对阴树脂的污染及复苏工艺

汽轮机油泄漏进入凝结水系统会对精处理混床树脂造成污染,对此,给出汽轮机油对阴树脂的污染与复苏系列试验结果.试验内容包括：在20,30,40℃条件下,分别用不同浓度汽轮机油（30,50,100,300,500,1 000,2 000,5 000,10 000 mg/L）浸泡阴树脂,检测其工作交换容量变化情况;在相同的条件下进行复苏处理,比较再生后的复苏效果.在浸泡时间（6,12,24 h）、浸泡温度及浸泡液pH值（7,8,9）变化时考察阴树脂的污染与复苏情况,比较使用不同复苏液时的复苏效果.结果表明：随着油浓度增大、溶液pH值降低及浸泡时间加长,使得阴树脂污染加重、复苏程度降低.复苏液10%NaCl＋2%NaOH＋3%Na3PO4＋0.2%OP-10具有较好复苏效果.

Anion exchange resin pollution by tuebine oil and it's recovery in condensate water treatment system

The anion exchange resin in condensate polishing equipment is polluted by the turbine oil leaked into the condensate water treatment system. Experimental results for the pollution and its recovery are presented in this paper. The work exchange capacity variety of the polluted and recovered anion exchange resin is investigated at different temperature （20,30,40 ℃ ） and different oil concentration （ 30, 50,100,300,500,1 000,2 000,5 000 , 10 000 mg/L） respectively. The pollution and recovery degree is evaluated at different immersed time （6,12,24 h） and different solution pH value （7, 8, 9）respectively. The comparison tests for different recovery solution the anion exchange resin pollution will increase and the are also carried out. Experiment results show that recovery degree will decrease with the turbine oil concentration increasing, the immersed time extending and the solution pH value decreasing. The recovery solution with 10% NaCl＋2% NaOH＋3% Na3PO4＋ 0.2% OP-10 has good regeneration efficiency.
