摘要：针对变压器油真空滤油工艺的诸多不足,探索将常温常压固定床吸附技术用于变压器油脱水的可行性,并考察了改性树脂、5A分子筛、活性炭、硅胶等吸附材料的性能。结果表明:在考察的吸附材料中,改性树脂脱水剂的性能最优,无水氯化钙次之,硅胶和5A分子筛的性能最差;当原料变压器油水质量分数为33μg/g时,在质量空速30 h^(-1)条件下进行固定床吸附脱水后,变压器油初期水质量分数达10μg/g以下;以固定床出口变压器油水质量分数大于20μg/g为脱水剂失活标准,新鲜改性树脂脱水剂的吸附容量为96.03 mg/g;吸水改性树脂可多次再生循环利用,再生后改性树脂脱水剂的吸附容量轻微下降。
In view of the many shortcomings of the vacuum filtering technology for transformer oil,the feasibility of applying the fixed bed adsorption process at room temperature and normal pressure to the dehydration of transformer oil was explored,the performance of different materials such as modified resin,5A zeolite,activated carbon,and silica gel was investigated.The results showed that the performance of modified resin dehydrating agent was the best,followed by the anhydrous calcium chloride,the silica gel and 5A zeolite.When the water content of the feed oil was 33μg/g,the initial water content at the outlet was less than 10μg/g after fixed bed adsorption dehydration at WHSV of 30 h^(-1).If taking the water content higher than 20μg/g as the deactivation standard,the adsorption capacity of fresh modified resin was 96.03 mg/g.The modified resin could be used for many times,but the adsorption capacity would be lightly decreased after regeneration.
