摘　　要：针对冶金液压润滑站设计一种高效污静电净油装置。本文首先基于液压油净化系统的静电净油机理,分析污染物颗粒在外加电场强度的液压油中的受力情况,并基于此分析外加电场强度、集尘体结构、油液流量、净化时间对于净油效率的影响;进一步发明可以净化一定含水量的高纳污静电净油装置,并完成其工业样机制作。完成了可净化一定含水量、高纳污静电净油系统的设计,整体设计中加入了吸油过滤器,油水分离器,预过滤器,污染度传感器及闭环控制模块,同时设计了一种新型的集尘体结构。静电净油过程中要求施加的电场具有一定强度和梯度,但外加的电场强度不能过大;线-筒电极配合紧密卷筒形集尘体结构产生的电场梯度较大,且该结构纳污能力强;流量不能过大;净化时间必须小于电泳力抵消静电斥力的时间。Objective:To design a high-efficiency dirty electrostatic oil cleaning device for metallurgical hydraulic lubrication station.Method:This paper first analyzes the force distribution of pollutant particles in hydraulic oil with external electric field strength based on the electrostatic oil purification mechanism of the hydraulic oil purification system.Based on this analysis,the influence of external electric field strength,dust collector structure,oil flow rate,and purification time on the oil purification efficiency is analyzed;Further simulate the field strength and oil purification process generated by different electrode combinations through software;Further invention of a high nanoparticle electrostatic oil purification device capable of purifying a certain water content,and completion of its industrial prototype production.Result:The design of a high capacity electrostatic oil purification system that can purify a certain water content has been completed.The overall design includes an oil suction filter,oil-water separator,pre filter,pollution level sensor,and closed-loop control module.At the same time,a new type of dust collection structure has been designed.Conclusion:The electrostatic oil purification process requires the applied electric field to have a certain strength and gradient,but the applied electric field strength cannot be too large;The electric field gradient generated by the tightly packed drum shaped dust collector structure with wire tube electrodes is relatively large,and this structure has strong pollution carrying capacity;The flow rate should not be too large;The purification time must be less than the time required for electrophoretic force to counteract electrostatic repulsion.
