Abstract

The invention relates to the technical field of waste lubricating oil pretreatment, in particular to a pretreatment distillation device and method for continuous regeneration of waste lubricating oil, the pretreatment distillation device comprises a case, and a first-stage distillation retort, a second-stage distillation retort and a third-stage distillation retort are arranged in the case side by side; meanwhile, distillation mechanisms are arranged in the multiple stages of distillation retorts, vacuum distillation treatment is conducted on the waste lubricating oil in the first-stage distillation retort, the second-stage distillation retort and the third-stage distillation retort in sequence, gas is blown into the waste lubricating oil in the vacuum distillation process of the waste lubricating oil, bubbles are continuously blown out of the interior of the waste lubricating oil, and the waste lubricating oil is continuously discharged. According to the waste lubricating oil distillation device, on one hand, the distillation efficiency of waste lubricating oil can be improved, on the other hand, an oil film is prevented from being formed in the distillation process, meanwhile, coke on the inner wall of the distillation retort is cleaned through the scraping frame and the scraping plate in the distillation treatment process, and the continuous operation efficiency of the distillation device is improved while the fraction effect of the waste lubricating oil is guaranteed.

Description

technical field [0001] The invention relates to the technical field of waste lubricating oil pretreatment, in particular to a pretreatment distillation device and method for continuous regeneration of waste lubricating oil. Background technique [0002] Lubricating oil is one of the important means to control friction and reduce wear in mechanical devices. It is widely used in occasions requiring mechanical operation. It is called the blood of machinery. Lubricating oil is a product with high added value extracted from petroleum. It is composed of lubricating base oil and lubricating oil additives, among which the mass fraction of base oil is 70% to 98%. Unlike fuel oil, which has substantial loss during use, the physical and chemical properties are caused by the continuous increase of impurities. Change and can not continue to use, become waste lubricating oil; [0003] The invention patent with publication number CN108211406A discloses a vacuum distillation equipment for ...
