【摘要】：变压器油中含有的腐蚀性硫二苄基二硫醚对变压器的安全稳定运行带来严重威胁。吸附除硫技术可以脱除绝缘油中的腐蚀性硫,从源头上解决腐蚀性硫对铜导线的腐蚀问题,但是吸附除硫的效率有待提高。设计了一种吸附剂-氧化剂复合体系,通过优化吸附剂、氧化剂、吸附剂粒径和吸附时间提升吸附效率。同时对经优化后的吸附剂-氧化剂复合体系处理后的绝缘油进行腐蚀性试验。试验结果表明:13X分子筛相对于目前广泛使用的白土等吸附剂对二苄基二硫醚腐蚀性硫的吸附效率更高。同时高锰酸钾与13X分子筛的复合使用提高了腐蚀性硫的去除效率。13X分子筛的粒径对吸附效果影响明显,通过优化,13X分子筛对绝缘油中二苄基二硫醚的去除率得到提高。吸附剂-氧化剂复合体系的吸附平衡时间较短,吸附处理4 h即可达到吸附平衡。
[Abstract]:The safe and stable operation of corrosive sulfur two benzyl sulfide containing two transformer oil in the transformer pose a serious threat. The removal of sulfur removal technology can insulation of corrosive sulfur in oil, to solve the problem of corrosion of corrosive sulfur copper wire from the source, but the adsorption desulfurization efficiency needs to be improved. Design a adsorbent - oxidant compound system, by optimizing the adsorption agent, oxidizing agent, adsorbent particle size and adsorption time improve the adsorption efficiency. At the same time corrosion test of insulating oil by adsorption agent - optimized oxidant compound system after treatment. The experimental results show that 13X molecular sieve adsorption efficiency relative to the currently widely used the clay adsorbent of two two benzyl sulfide corrosive sulfur is higher. At the same time Potassium Permanganate and 13X composite molecular sieve is raised by the use of corrosive sulfur removal efficiency of.13X zeolite particle size on adsorption effect Obviously, through optimization, the removal rate of two benzyl two thioether in the insulating oil was improved by 13X zeolite. The adsorption equilibrium time of the adsorbent oxidant composite system was shorter, and the adsorption equilibrium could reach 4 h after adsorption treatment.
