Problems solved by technology

Waste engine oil, waste lubricating oil and all kinds of waste oil, tire oil, rubber oil crude oil are distilled by single kettle or soil method, and the diesel oil obtained by refining with acid and alkali in the later stage contains sulfides, nitrogen compounds, organic acids and asphalt to varying degrees Colloids, olefins, dienes, etc., resulting in diesel oil with dark color, strong smell, unstable quality, and will deteriorate quickly after a little storage

Embodiment 1

[0017] Metal removal machine and impurities system: The metal mechanical impurities in the B-type waste oil after the sedimentation treatment are removed through a magnetic filter and a centrifugal oil purifier. 2) Weak negative pressure distillation system (vacuum is 2000Pa): the oil product after the removal of impurities is pumped to the preheater and the preheated material enters the middle of the distillation tower, and is heated to 120℃ in the reboiler (Working temperature) The water and gasoline in the waste oil are steamed from the top of the tower into the condenser for condensation, and then separated into the oil-water separator and discharged. The lubricating oil and high-boiling parts in the materials are separated at the bottom of the distillation tower. The materials from which water and gasoline are removed are sent from the bottom of the distillation to the thin-film evaporator through a transfer pump (the working vacuum is 200Pa, and the working temperature is:...

Embodiment 2

[0019] The other steps are the same, and the changes are as follows: the vacuum degree of the weak negative pressure distillation system is 4000 Pa, and the working temperature is 80°C; the working vacuum degree of the thin film evaporation system is 400 Pa, and the working temperature is 190 ℃. The working vacuum degree of the short-path distillation system is 10 Pa, and the working temperature is 250°C.

Embodiment 3

[0021] The other steps are the same, and the changes are: the vacuum degree of the weak negative pressure distillation system is 6000 Pa, and the working temperature is 100°C; the working vacuum degree of the thin film evaporation system is 600 Pa, and the working temperature is 200 ℃. The working vacuum degree of the short-path distillation system is 20 Pa, and the working temperature is 300°C.

Abstract

The invention discloses an industrial waste lubricating oil regeneration process which comprises a metal mechanical impurity removing system, a weal negative pressure distilling system, a decompression evaporating system and a short-range distilling system. The technical scheme of the invention has the advantages of ensuring the normal running of equipment, prolonging the service life of the equipment, saving lubricating oil materials, saving energy and improving economic benefits and social benefits.

Description

Technical field [0001] The invention relates to an industrial waste lubricating oil regeneration process, belonging to the technical field of waste oil recovery. Background technique [0002] The waste lubricating oil replaced from various machinery, vehicles, and ships is discarded due to the large amount of colloid and oxide produced by external pollution during use, which reduces or even loses its due effect. Although the output is huge, It is famous, but because of its abnormally low economic value, it has always been in the status of "waste". In order to dispose of it every year, it is discarded or incinerated regardless of the consequences. This is not only a problem of large-scale environmental pollution, but more importantly, it involves the energy crisis that is constantly arousing in our country. According to forecasts, the global petrochemical energy sources are 39 years for oil, 60 years for natural gas, and 211 years for coal, and they are mainly distributed in the ...
