摘要
陕西某电厂供热机组在供暖期内发生汽封漏气,导致汽轮机润滑油严重乳化,危害机组运行安全。为了不影响机组正常供暖,研究并验证了不同在线处理方法的处理效果。结果表明,采用极性诱导选择性吸附剂对运行油进行在线再生,可将油的破乳化度降至极限值,使乳化油在极短时间内破乳化,油与水在油箱中具有充足的分离时间,彻底解决了运行油乳化问题,为机组运行安全提供了保障。
The steam seal leakage occurs in the heating unit of a power plant in Shaanxi during the heating period,causing serious emulsification of the lubricating oil in the turbine and endangering the safety of the generator set operation.In order to avoid affecting the normal city heating,the effects of various online processing methods are studied and tested.The results show that the using of a polar selective adsorbent on the online regeneration of the oil is able to maximum the the demulsification reduction,making it demulsified in a very short time,and giving sufficient time for the separation of the oil and the water,This method completely solves the problem of the oil emulsification,which ensures the safe operation of the unit.
