Abstract

The invention discloses a separation device and method for removing impurities in waste lubricating oil, and relates to the technical field of separation of impurities in lubricating oil. The separation device cooperates with an alkali neutralization settling tank, a reverse osmosis membrane module, a hydrofining distillation tank and a decolorization refining tank It has the functions of alkali neutralization, sedimentation, water phase infiltration, removal of metal impurities and asphaltenes, hydrofining, stripping distillation, decolorization and refining of waste lubricating oil, and is suitable for high acid value and oxidative deterioration. , Waste lubricating oil with high content of metal asphaltene and complex composition can be separated to obtain lubricating oil base oil with high purity and low impurities. The regeneration recovery rate of waste lubricating oil is improved, the cost of water is reduced, the process setting of the impurity removal method is reasonable, the treatment steps are few, and the impurity removal effect is good.

Description

technical field [0001] The invention relates to the technical field of separation of impurities in lubricating oil, in particular to a separation device and method for removing impurities in waste lubricating oil. Background technique [0002] After a long time of use, the processing performance of lubricating oil decreases and the wear increases. Therefore, new oil should be replaced after a certain period of use. Since the amount of used lubricating oil replaced every year in the world is quite large, the treatment of waste lubricating oil has also attracted more and more attention; [0003] At present, there are roughly three methods for the regeneration of waste lubricating oil: (1) For waste lubricating oil that is not seriously deteriorated and mainly mixed with water and solid impurities, the repurification process is adopted; Waste lubricating oil with many oxidation products such as film is treated with chemical substances such as sulfuric acid and adsorbents such a...
