Description

Technical Field

[0002] Industrial waste oil refers to motor oil that has been mixed with impurities such as water, dust, other miscellaneous oils, and metal powders produced by wear and tear of machine parts during use; secondly, it refers to motor oil that has gradually deteriorated and generated organic acids, colloids, and asphalt-like substances. The regeneration of waste motor oil is to remove impurities in the motor oil through sedimentation, distillation, acid washing, alkaline washing, filtration and other steps. In the distillation step, the waste oil that has been treated with sedimentation to remove the sediment is introduced into a distillation device and heated for atmospheric distillation. Gasoline is distilled at 180°C, diesel is distilled at 180-360°C, and what is left is motor oil. If it is known that there are no impurities such as gasoline and diesel in the waste motor oil, this step can be omitted.

[0003] In the prior art, a water pump drives the water in the water tank to flow through a cooling water pipe and then flows back to the water tank for natural cooling and then is circulated for use, and the heat energy of this part of the hot water is wasted.

[0004] For example, a distillation device for recovering industrial waste oil disclosed in Chinese patent CN215427371U utilizes a waste oil sedimentation container as a condensation device, thereby eliminating a special water tank and a special heating device for the waste oil sedimentation container, and achieving good energy-saving effect.

[0005] However, during the process of distilling waste oil, coking will occur on the inner wall of the still, which makes it inconvenient to clean the still.
