Distillation recovery device for waste lubricating oil regeneration

Abstract

The present invention relates to a distillation recovery device for waste lubricating oil regeneration. The device comprises a raw material tank, a dehydration tower, a heating furnace, a vacuum tower, a stripping tower and an oil-water separator, the raw material tank is connected with a plurality of secondary heat exchangers and a residual oil heat exchanger in series through a raw material oilpump, and the residual oil heat exchanger is connected with the middle of the dehydration tower; the bottom of the dehydration tower is connected with a dehydration bottom pump, the dehydration bottompump is connected with a plurality of primary heat exchangers in series, the primary heat exchangers are connected with the heating furnace, and the heating furnace is connected with the vacuum tower; a multi-line oil collecting tank in the vacuum tower is connected with a multi-line buffer tank in the stripping tower, the multi-line buffer tank is connected with a multi-line transfer pump, the multi-line transfer pump is coupled and connected with the primary heat exchangers and the secondary heat exchangers, the secondary heat exchangers are connected with a pressure reduction cooler, and the pressure reduction cooler is connected with a product tank. The distillation recovery device can achieve recovery of waste lubricating oil with complex components, is low in energy consumption, andis suitable for industrial large-batch treatment.

Description

technical field [0001] The invention relates to a distillation recovery device for regeneration of waste lubricating oil, which belongs to the technical field of separation. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is used in almost all mechanical equipment. Lubricating oil used for a long time often contains impurities such as moisture, mechanical residues, and carbon deposits, which will affect the use effect of the lubricating oil. [0003] At present, the devices used for waste lubricating oil recovery are often only for simple filtration or odor removal, which are not suitable for the recovery of complex waste lubricating oil, and are not suitable for industrialized treatment. In re...

Problems solved by technology

Lubricating oil is used in almost all mechanical equipment. Lubricating oil used for a long time often contains impurities such as moisture, mechanical residues, and carbon deposits, which will affect the use effect of the lubricating oil.

[0003] At present, the devices used for waste lubricating oil recovery are often only for simple filtration or odor removal, which are not suitable for the recovery of complex waste lubricating oil, and are not suitable for industrialized treatment

In reality, the waste lubricating oil often has complex impurity components, and because the lubricating oil used by different machines is often different, the waste lubricating oil is often a mixture of different types of lubricating oil. Distillation recovery device for waste lubricating oil regeneration, which has very important practical value
