In above scheme, preheater is equipped between dehydrating tower and dry deodorizing tower.
Further, the gas outlet at the top of rectifying column connects two-stage condensation device, and light diesel fuel is condensed into liquid through two-stage condensation device
Enter light diesel fuel storage tank after body.
Further, the solid residue that secondary molecules destilling tower is discharged enters in residue storage tank.
Further, the distillation in first order molecular destilling tower and secondary molecules destilling tower is all made of conduction oil electric heating,
Oil temperature is heated to 320 DEG C by 260 DEG C.
Further, first order molecular destilling tower and the temperature of molecular distillation in secondary molecules destilling tower control positive and negative deviation not
More than 2 DEG C.
Further, the water content in raw material is down to 2% or less under negative pressure state by dehydrating tower.
The utility model has the following beneficial effects: the system processing temperature is lower than 300 DEG C, raw material heated time is only tens
Second.It is few to crack composition, it is of light color, all kinds of impurity in waste lubricating oil are disposed, while having carried out decolorization, be can be obtained excellent
Matter lubricating oil, remaining is for petrol and diesel oil, pitch, gear oil etc., and the effective product of gained accounts for the 97.5% of total raw material quality, high income,
Energy conservation and environmental protection.And the subsequent purification of this system is simple, does not have to pickling, production process environmental protection belongs to friendly process.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model；
Attached drawing 2 is the process flow chart of the utility model.
Specific embodiment:
It please refers to shown in Fig. 1, Fig. 2, is the structural schematic diagram of the preferred embodiment for the utility model, the utility model is
A kind of abandoned mine oil recovery system, main includes the centrifugal separator 1 set gradually, Liquid liquid Separation device 2, dehydrating tower 3, dry deodorization
Tower 4, rectifying column 5, first order molecular destilling tower 6, secondary molecules destilling tower 7, wherein be equipped between dehydrating tower 3 and dry deodorizing tower 4
Preheater 34；The gas outlet at the top of rectifying column 5 connects two-stage condensation device 51, and it is laggard that light diesel fuel through two-stage condensation device is condensed into liquid
Enter light diesel fuel storage tank 52.First order molecular destilling tower 6 is separately connected corresponding bleacher 8, bleacher 8 with secondary molecules destilling tower 7
In be respectively arranged with atlapulgite, and the dormant oil that flows out of bleacher 8 enters in finished pot 10 after accurate filter 9 and collects, and two
The solid residue that grade molecule destilling tower 7 is discharged enters in residue storage tank 71.
Abandoned mine oil recovery system of the invention, process flow are broadly divided into four units.
First unit: filtering, dewatering unit
Main purpose is to slough the water of the overwhelming majority in raw material abandoned mine oil, general suspended machine
Tool impurity and with the mechanical admixture of colloidal state stable dispersion, to obtain cleaner useless lubrication
Oily raw material.Detailed process is: mechanical admixture being removed by abandoned mine oil by centrifugal separator 1, then passes through liquid liquid
Most moisture content is separated off by separator 2, then passes through dehydrating tower 3 under certain negative pressure state for the water content in raw material
It is down to 2% and enters next unit hereinafter, the cleaner raw material obtained in this way is squeezed into storage tank and waited.
Second unit: dry, deodorization unit
Main purpose is to completely remove moisture and light component micro in raw material, while removing raw material
In stink.Detailed process is: inherent filtration in future, dewatered abandoned mine oil are increased to certain temperature by preheater 34
Degree, subsequently into dry deodorizing tower 4, since high-performance filler being distributed in tower and there are high vacuum, moisture and light
Component is easy to be removed, and the molten low-boiling point material for having peculiar smell in the feed, the steam being passed into are taken away, tower bottom must
Clean material has been arrived, next unit is prepared to enter into.
Third unit: rectifying and molecular distillation unit
Main purpose, which is precisely separated out, influences the key indexes such as lubricating oil viscosity index, flash-point
Light diesel fuel ingredient, and effective component is divided into the thick lubricating oil family of two kinds of different stages.Tool
Body process is: be pumped in the rectifying column 5 of built-in high separability energy filler by dry, deodorization waste oil, compared with
Under high vacuum state, light diesel fuel component is accurately cut completely from tower top and is separated, and is condensed into liquid by two-stage condensation device 51
Enter light diesel fuel storage tank 52 after body；The material of removal light diesel fuel flows back to tower bottom, subsequently into first order molecular destilling tower 6, due to dividing
Sub- destilling tower works under a high vacuum, therefore the low viscosity ingredient of material is just distilled off at a lower temperature, inside
It sets under condenser effect, gas phase conversion is got off for liquid phase condensate, it will enter storage tank as light lubricating oil；It is not distilled out
More highly viscous material be pumped directly secondary molecules destilling tower 7 again, in the case where temperature higher compared with previous stage, effectively
, the ingredient of viscosity higher distilled again as heavy grease, into storage tank.The material that can not be distilled out is as residue
(main component is: additive, pitch etc.) is discharged into residue storage tank 71.First order molecular destilling tower 6 and secondary molecules destilling tower 7
In distillation be all made of conduction oil electric heating, oil temperature is heated to 320 DEG C by 260 DEG C.And the temperature control precision of molecular distillation
More demanding, positive and negative deviation is no more than 2 DEG C.
Unit the 4th: clay-filtered unit
Main purpose is to improve the lustre index of lubricating oil.Detailed process is: light, heavy lubricating oil
The bleacher 8 equipped with atlapulgite is respectively enterd, bleacher can operate in parallel or series, and bleacher 8 itself needs
Be preheating to certain temperature in advance, a small amount of tiny carclazyte particle may be carried in the lubricating oil after bleacher 8 secretly, enter at
It must be removed by accurate filter 9 before product tank, then enter finished pot 10 by the lubricating oil of accurate filter 9 and receive
Collection.
For embodiment, gained lubricating oil quality is detected, such as the following table 1:
Table 1
Certainly, illustrated above is only the preferred embodiment of the utility model, and the use of the utility model is not limited with this
Range, therefore, it is all made in the utility model principle it is equivalent change should be included in the protection scope of the utility model.
