Industrial lubricating oil purification and repair process integration device

Abstract

The invention discloses an industrial lubricating oil purification and repair process integration device. The process comprises the steps of: preheating, high speed centrifugation, polymer organic membrane coalescence, dehydration and filtration, primary electrosorption separation, dispersive vacuum dehydration, secondary electrosorption separation and the like; the device comprises a primary heater, a feed oil pump, a centrifuge and a centrifuge receiving oil tank; an outlet end of the centrifuge receiving oil tank is connected with a polymer organic membrane coalescing and dehydrating filter, and the polymer organic membrane coalescing and dehydrating filter is connected with a first electric separation device; the first electric separation device is provided with an electrostatic generator and a controller, and the top of the first electric separation device is provided with a rebreather and a high and low liquid level controller. The industrial lubricating oil purification and repair process integration device has the advantages that by using a pure physical method for processing, functional additives of lubricating oil are not lost; by adopting a prying assembly combined integration way, the device is convenient for a user to use on customer sites with multiple points and wide areas, waste lubricating oil can be directly used after being subjected to purification, repair and life extension treatment, and the economic benefit is improved.

Description

technical field [0001] The invention relates to a process for treating industrially used lubricating oil, in particular to an assembly process and device for purifying and repairing industrially used waste lubricating oil, and belongs to the field of industrial waste lubricating oil treatment. Background technique [0002] The purification, repair and harmless treatment of industrial used lubricating oil has always been a hot research topic in the industry. Processes such as pressure distillation are mostly treatment methods involving strong acid and alkali and chemical solvents. These processes will not only produce secondary hazardous waste that is more difficult to handle. Moreover, it will inevitably cause the loss or even removal of functional additives in lubricating oil, so that lubricating oil products with specific functions will become lubricating oil base oils, leading to direct use after treatment with waste lubricating oils that are difficult to prolong their li...
