Abstract
The invention discloses a recovery process for lubricating oil. The recovery process comprises the following steps: S1, precipitation; S2, filtering; S3, de-watering; S4, adsorption with activated clay; and S5, filtering. Compared with newly-prepared lubricating oil, lubricating oil obtained after filtering has identical viscosity and calorific value except color. According to the invention, impurities in waste lubricating oil are removed through physical means, and additives are added; and since a simplest manner with lowest cost is employed for treatment of the waste lubricating oil, harm to environment and human health caused by recovery of lubricating oil with chemical approaches can be mitigated.
Description
Technical field
The present invention relates to a kind of recovery process of lubricating oil, more particularly to a kind of for during mechanical lubrication
The waste lubricating oil recovery process for changing.
Background technology
With modern industry development while the demand of lubricating oil is increasingly increased, while generating a large amount of
Waste lubricating oil, the waste lubricating oil for mainly changing during mechanical lubrication.These greasy dirts are frequently as nothing
Outwelled with waste or the nonoculture burning energy, not only the energy is caused greatly to waste, and environment is caused sternly
Heavily contaminated.Therefore carrying out regeneration to waste lubricating oil has highly important meaning：First it is energy saving, becomes
Waste be changed into values, is conducive to making full use of for petroleum resources；Next to that analyze from the degradation mechanism of lubricating oil, it is big absolutely
The so-called waste lubricating oil in part is not really scrapped, the rotten simply which part hydro carbons of oil product, accounts for
10～25%, remaining most of hydro carbons composition is still the main viscous carrier and active ingredient of lubricating oil, if logical
The method crossed physically or chemically removes the rotten dirt of waste lubricating oil and impurity, just waste lubricating oil can generated matter
It is real after measuring satisfactory base oil, then formulated doping, it is possible to obtain superior in quality lubricating oil
Now turn waste into wealth.
The content of the invention
In view of the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of lubrication
The recovery process of oil, is primarily directed to the recycling of waste lubricating oil changed during mechanical lubrication.
For achieving the above object, the invention provides a kind of recovery process of lubricating oil, comprises the steps：
S1, precipitation：Waste oil is utilized the difference of proportion in settling tank, the material that weight is larger passes through
Standing makes it be precipitated to bottom；
S2, filtration：By the waste oil after staticly settling in S1 using the gold in carry magnet filter coarse filtration waste oil
Category impurity；
S3, eliminating water：Lubricating oil after filtration is placed in reactor, heating is stopped after being warmed up to 70～80 DEG C,
Be allowed to settle 20-26 hours, then by after the waste oil collecting on top layer to waste oil pool eliminating water by the bright of waste oil surface
Water is drained, and is then slowly warmed up to 100-140 DEG C and is incubated 1～3 hour and (when oil temperature is close 100 DEG C,
Slowly heat, prevent oil to be boiling over), fall moisture evaporation and oil is not stirred, pasta emerges black oil gas i.e.
Can；
S4, atlapulgite absorption：Oil is warmed up to into 120～140 DEG C of insulations, atlapulgite is added while stirring,
Described atlapulgite usage amount is about the 6%-8% of oil mass, after adding atlapulgite, continues to stir 15～45
Minute, constant temperature stands 8～24 hours at 110～120 DEG C；
S5, filtration：Excessive fuel consumption after standing in S4 is carried out into smart filtration using plate frame filter while hot, is filtered
After obtain final product qualified base oil.
The invention has the beneficial effects as follows：Oil product after Jing filtrations process of the present invention, with new lubricating oil ratio is done
Compared with except color and luster, no matter viscosity or calorific value do not have other bad impacts, the present invention passes through physics
Means remove the impurity of waste lubricating oil, and add additive, are processed with the mode of most simple least cost
Waste lubricating oil, it is possible to reduce be good for the harm of environment and to human body when reclaiming lubricating oil using chemical method
Health.
