Description
Technical field
The invention belongs to lubricant oil regeneration to utilize technical field, and in particular to one kind is purified using heavy-duty engine waste lubricating oil
The method for preparing anti-corrosive grease base oil.
Background technology
Lubricating oil year sales volume in China's has substantial amounts of waste lubricating oil to produce, at present these waste lubricating oils every year more than 4,000,000 tons
Fuel oil auxiliary material is often used as, is not fully used, causes the great wasting of resources, needs badly and seeks a waste oil time
Receive the approach and method utilized.
Anti-corrosive grease is to maintain the rustless high-end fine product in metal surface, and preparing anti-corrosive grease using waste lubricating oil is
The effective way that one waste lubricating oil efficiently utilizes, its have the advantage that for：In waste lubricating oil containing substantial amounts of anti-corrosive grease into
Point, the base oil of anti-corrosive grease is prepared using it, the cost of anti-corrosive grease can be substantially reduced, realizes the reasonable effective of waste lubricating oil
Utilize.
In locomotive operation process, lubricating oil is acted on by high temperature, air oxidation etc., and gradual aged deterioration produces pitch class
The impurity such as colloid, organic acidic substances, coke powder, simultaneously because also to produce metal dust etc. miscellaneous for the friction of metallic element
Matter, these impurity are all blended in waste lubricating oil.Chinese patent CN104498173A discloses a kind of waste lubricating oil containing glue again
Generation method, it uses concave convex rod concentrate adsorbent, high alumina concave convex rod concentrate adsorbent, siliceous sedimentary rock raw ore and siliceous volcano acid
Property lava raw ore mix molecular sieve etc. obtained by calcining and be used as adsorbent, point three steps adsorb the colloid in waste lubricating oil.This method
Most of colloid can be removed, but its adsorbent amount is big, cost of manufacture is high, and be stripped of in waste oil and be beneficial to prepare antirust oil
The composition of fat, the acid impurities contained by its waste oil, carbon, metal impurities are difficult to eliminate in addition.Chinese patent CN106833739A
A kind of used oil regenerated method is disclosed, in its step of modification sodium bentonite powder one absorption used oil using 200 mesh
Colloid, such as removing such as mor, metal impurities and carbon of other impurity is incomplete, and filter process resistance is big, obtains
Oil quality is poor.
The content of the invention
It is an object of the invention to overcome impurity present in existing Spent lube reclamation process to remove not thorough, adsorbent
The deficiencies of dosage is big, regeneration oil quality is poor, there is provided one kind prepares antirust oil aliphatic radical using heavy-duty engine waste lubricating oil purification
The method of plinth oil.This method is adsorbed to heavy asphalt colloid first, is then purified using alkali substance reaction and is removed acidity
Impurity, then adsorbed using magnetic particle and remove metal impurities, finally using active carbon layer adsorption bleaching, above-mentioned technique is effective
The active ingredient of anti-corrosive grease base oil is remained while removing various impurity.The anti-corrosive grease prepared using the inventive method
Adhesive force is strong, has good blending and confining force to corrosion inhibiter.
To achieve the above object, the technical solution adopted in the present invention is as follows：
A kind of method for preparing anti-corrosive grease base oil using heavy-duty engine waste lubricating oil purification, detailed process are as follows：Will
After waste lubricating oil heating, it is utilized respectively sticky particles, alkaline matter, magnetic particle, activated carbon and carries out adsorption filtration, finally obtain
Anti-corrosive grease base oil after purification.
In such scheme, filtered after waste lubricating oil is stood overnight first, be then heated to 50-80 DEG C.
In such scheme, according to the solid mass ratio of oil (the referred to as solid ratio of oil, similarly hereinafter) 1:0.1-0.3 is to the waste lubricating oil after heating
Middle addition sticky particles, filtered after quickly stirring 5-30min.
In such scheme, according to oil admittedly than 1:0.05-0.2 adds into the waste lubricating oil after sticky particles adsorption treatment
Alkaline matter calcium oxide or calcium hydroxide, quick centrifugal filtration after stirring 5-30min.
In such scheme, according to oil admittedly than 1:0.1 to useless after alkaline matter calcium oxide or calcium hydroxide adsorption treatment
Magnetic particle is added in lubricating oil, is filtered after quick stirring 5-30min with active carbon layer.
In such scheme, the sticky particles are selected from modified kaolin, modified magnesium alumino metasilicate salt mine soil, modified active oxidation
One kind in aluminium, the size controlling of sticky particles are controlled in 100-1000m in 60-100 mesh, specific surface area2/g。
In such scheme, the magnetic particle is selected from natural magnet (such as ferroso-ferric oxide), magnetic iron ore, neodymium-iron-boron
One kind in body, samarium-cobalt magnet, alnico magnet, the particle diameter of magnetic particle is 10-50 mesh, and the size of activated carbon granule is 1-10
μm or so.
In such scheme, the waste lubricating oil is discarded after heavy truck, ship, train, heavy tractor replacing
Lubricating oil.
Compared with prior art, the invention has the advantages that：(1) rate of recovery is high, cost is low, technique is simple, behaviour
The property made is strong；(2) targetedly progressively the crude asphalt colloid in adsorbing and removing waste lubricating oil, acid impurities (such as organic acid), gold
Belong to impurity (such as iron, nickel, cobalt), foreign pigment (such as carbon particulate), obtained anti-corrosive grease basis oil quality is preferable；(3) keep away
The distillation and solvent extraction operation in traditional Spent lube reclamation process are exempted from, energy-conserving and environment-protective, have avoided caused by traditional handicraft
Acid sludge, waste water etc. pollute；(4) C5-C7 asphalitines clearance reaches 60%-80% in the waste lubricating oil handled by the present invention, has
Machine acid matter clearance reaches 80%-90%, and for iron filings particulate removal rate up to more than 90%, lubricating oil colourity becomes shallow brown by aterrimus
Color；(5) the anti-corrosive grease adhesive force prepared using the inventive method is strong, has good blending and confining force to corrosion inhibiter.
