A distillation recovery device for regeneration of waste lubricating oil

Abstract

The invention relates to a distillation recovery device for regeneration of waste lubricating oil, which includes a raw material tank, a dehydration tower, a heating furnace, a decompression tower, a stripping tower and an oil-water separator. The raw material tank is connected in series by a raw material oil pump. A secondary heat exchanger and a residual oil heat exchanger, the residual oil heat exchanger is connected to the middle part of the dehydration tower; the bottom of the dehydration tower is connected with a dehydration bottom pump, and the dehydration bottom pump is connected in series with several primary heat exchangers Heater, the primary heat exchanger is connected to the heating furnace, and the heating furnace is connected to the decompression tower; the multi-line oil collection tank inside the decompression tower is connected to the multi-line buffer tank inside the stripping tower, The multi-line buffer tank is connected to a multi-line transfer pump, and the multi-line transfer pump is coupled to a primary heat exchanger and a secondary heat exchanger. The secondary heat exchanger is connected to a decompression cooler, and the decompression cooler is connected to a product tank. The distillation recovery device can realize the recovery of waste lubricating oil with complex components, has low energy consumption, and is suitable for industrialized mass processing.

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
