Abstract

The invention discloses a waste lubricating oil regeneration device and a regeneration technology thereof. The waste lubricating oil regeneration device comprises at least one heat exchanger, at least one cooler, a lubricating oil heating furnace and at least one distilling tower, wherein a pipeline containing waste lubricating oil is connected with an inlet of a shell pass of the heat exchanger; a pipeline is arranged at an outlet of the shell pass of the heat exchanger and is connected with a material inlet at the middle lower part of the lubricating oil heating furnace; a pipeline is arranged at a material outlet of the lubricating oil heating furnace and is connected with the middle upper part of the distilling tower; a pipeline is arranged on a tower kettle of the distilling tower and is connected with an inlet of a tube pass of the cooler; a finished lubricating oil pipeline and a pipeline for communicating with the waste lubricating oil pipeline are arranged at an outlet of the tube pass of the cooler. The waste lubricating oil regeneration device has the advantages that the to-be-treated waste lubricating oil in the pipeline exchanges heat with the raw material which does not enter the treatment process by the heat exchanger, so that the consumption of heat energy is reduced; the waste lubricating oil is heated to the required temperature by the lubricating oil heating furnace, and then is sent into the distilling tower, and multiple types of lubricating oil are separated out according to different fractions, so that the recycling rate is high.

Description

Technical field [0001] The invention relates to the field of lubricant production equipment, in particular to a waste lubricant regeneration device and a regeneration process thereof. Background technique [0002] Lubricating oil is a liquid lubricant used on all kinds of machinery to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Over time, these lubricating oils widely used in vehicles, ships, and machinery will be contaminated by air, water, dust, miscellaneous oil, and metal impurities generated by the wear of mechanical parts, and even deteriorate. Continued use can cause mechanical failure. Therefore, the lubricant must be replaced in time. [0003] Waste lubricating oil has the dual characteristics of pollution and resources: improper handling will cause serious environmental pollution, but reasonable recycling can become a valuable resource. On the one hand, man...
