Problems solved by technology

[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 strong alkali and chemical solvents. These processes will not only produce secondary hazardous waste that is more difficult to treat
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 life. cause huge economic losses

Embodiment 1

[0029] For example: No. 46 turbine oil in use: cleanliness greater than grade 12 (NAS-1638), moisture content 310mg / kg, acidity 0.08mgKOH / g, iron: greater than 6 mg / Kg. Including the following steps:

[0030] 1. Preheating: heat the raw materials to 58°C.

[0031] 2. High-speed centrifugal separation: The centrifuge speed is greater than 4500r / min, the separation factor Fr is greater than 3500, the centrifugal acceleration is greater than 3000g, and the particles with a particle size greater than 30μm are removed.

[0032] 3. Polymer organic membrane filtration: Polymer organic membrane coalescence dehydration filter is used to remove particle pollutants and part of the water with a particle size above 15 μm.

[0033] 4. First-level electroseparation: first-level electrosorption separation (voltage 1100V, current 12mA), focusing on the removal of metal debris particles.

[0034] 5. Distributed vacuum dehydration: reheat to 63°C in the second stage, enter the distributed vacu...

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...
