Between control within 30s；
Reclaiming light components, the lubricating base oil light components that distillation evaporates after processing uses
Subzero 15 DEG C of chilled waters are anxious to be frozen and reclaims；
Purify, the lubricating base oil of recovery is sprayed on random packing through spray equipment, randomly
By vapours below filler, utilize that superheated steam takes away in lubricating base oil light components is different
Taste；
Cooling, the lubricating base oil after purification enters serpentine coil, makes to be cooled with circulating water；
Ultraviolet irradiates, and the lubricating base oil after cooling is passed through in storage tank and flows into described
The glass tubing that storage tank is connected, is filled with the noble gas of discord lubricating base oil reaction in storage tank,
Use the lubricating base oil that strong ultraviolet radiation is passed through in glass tubing；
Finished product storage tank, the lubricating base oil tinning in the glass tubing will crossed through strong ultraviolet radiation is deposited
Storage.
Preferably, in above-mentioned a kind of yellowing-resistant lubricating base oil processing method, also include step
Rapid:
Impurity screening, the lubricating base oil light components after recovery is through two-stage activated carbon adsorption
Filter, goes the removal of impurity.
Preferably, in above-mentioned a kind of yellowing-resistant lubricating base oil processing method, ultraviolet shines
Penetrating in step, noble gas is carbon dioxide.
Preferably, in above-mentioned a kind of yellowing-resistant lubricating base oil processing method, ultraviolet shines
Penetrating in step, glass tubing is U-shaped glass tubing.
Invention additionally discloses a kind of lubricating base oil making and processing in aforementioned manners, viscosity is low,
Colourless, free from extraneous odour, irradiates for a long time through ultraviolet simultaneously and also will not produce Yellowing, purity
Height and dependable performance.
Compared with prior art, the present invention has the following technical effect that
Using lubricating base oil prepared by technical solution of the present invention, viscosity is low, colourless, free from extraneous odour,
Irradiate for a long time through ultraviolet simultaneously and also will not produce Yellowing, purity height and dependable performance.
The present invention utilizes super critical point flash evaporation technology, enters lubricating base oil under conditions of end vacuum
Row distillation, protects the molecular structure of light components greatly.
Detailed description of the invention
Below the technical scheme in the embodiment of the present invention is clearly described.Obviously, retouched
The embodiment stated is only a part of embodiment of the present invention rather than whole embodiments.Based on
Embodiment in the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, broadly falls into the scope of protection of the invention.
As it is shown in figure 1, the open a kind of yellowing-resistant lubricating base oil processing method of the present invention, specifically
Comprise the steps:
Extract light components, choose hydrorefined 60N lubricating base oil, in residual voltage 20Pa,
Carrying out the flash distillation of very short time under super critical point condition of high vacuum degree environment, vapo(u)rizing temperature controls
165-170 DEG C, distillation time controls within 30s；
Reclaiming light components, the lubricating base oil light components that distillation evaporates after processing uses
Subzero 15 DEG C of chilled waters are anxious freezes and reclaims, it is to avoid after distillation, oil is lived again because of remaining temperature
Jump and aoxidize；
Impurity screening, the lubricating base oil light components after recovery is through two-stage activated carbon adsorption
Filter, goes the removal of impurity；
Purify, the lubricating base oil of recovery is sprayed on random packing through spray equipment, randomly
By vapours below filler, utilize that superheated steam takes away in lubricating base oil light components is different
Taste, the oil product colorless and odorless produced, purity reaches more than 99%；
Cooling, the lubricating base oil after purification enters serpentine coil, makes to be cooled with circulating water,
Ensure that oil product will not aoxidize because there being temperature；
Ultraviolet irradiates, and the lubricating base oil after cooling is passed through in storage tank and flows into described
The U-shaped glass tubing that storage tank is connected, uses strong ultraviolet radiation to be passed through the profit in U-shaped glass tubing
Sliding base oil；Filling CO 2 in storage tank, carbon dioxide is noble gas, will not be with oil product
Reacting, oil product in the absence of oxygen, through the irradiation of intensive ultraviolet, utilizes short
The energy of ripple ultraviolet, rearranges molecular structure of petroleum products.Wherein unsaturated structure is made to combine,
Level off to saturated.Rather than to being combined with oxygen below.
Finished product storage tank, the lubricating base oil dress in the U-shaped glass tubing will crossed through strong ultraviolet radiation
