Abstract
The invention relates to a waste oil regeneration production process, which comprises: filtering to remove metal impurities, filtering to remove large impurities, reducing pressure and dewatering, carrying out molecular distillation purifying, and filtering and polishing. According to the present invention, the pure physical separation is used, the product quality is stable, no secondary pollution is generated, the separation effect is good, the product purity is high, and various finished product lubricating oils for industrial equipment, transportation vehicles and the like can be blended by adding various additive to the product.
Description
Technical field
Present invention relates to a kind of waste oil regeneration production process, belong to waste oil regeneration production process field.
Background technology
At present, most of waste oil is purchased with waste oil regeneration production process processing of poor quality inferior mixing petrol and diesel oil or the oil that makes a fire by little oil plant, these illegally little oil plant be the illegal enterprise that country prohibites, and sternly controlled.The oil quality of the regeneration that existing waste oil regeneration production process has is not good, some complex process, and production cost is high.
Content of the invention
The oil quality that the purpose of the present invention is aiming at the regeneration that existing waste oil regeneration production process has at present is not good, some complex process, and equipment investment is big, the deficiency of production cost height, and provides a kind of oil quality of regeneration measured waste oil regeneration production process.
Its production craft step is:
1) cross and filter metal impurities: by waste oil under conditions of pressure 0.1-0.5mpa, so that waste oil is filtered by magnetic filter, the metal impurities in waste oil are removed；
2) cross filter miscellaneous greatly: the waste oil of metal impurities will be removed under conditions of pressure 0.1-0.5mpa, and make the waste oil of removing metal impurities pass through blue formula filter, the large granular impurity in waste oil is removed；
3) blood pressure lowering dehydration: with pump, the waste oil of above-mentioned removing large granular impurity is delivered to preheater and be preheated to after 100-120 DEG C, be re-fed in membrane evaporator, after processing through membrane evaporator；
Lower boiling water therein, gasoline, diesel oil enter in light component pans after plate-type condenser condensation, when the liquid level of light component pans reaches high level, by being pumped into oil water separator, remove moisture therein, reclaim gasoline therein, diesel oil, the material not evaporated therein then enters in heavy constituent tank；
4) molecular distillation purification:
Material in heavy constituent tank is delivered to reheater and is heated up to after 300-320 DEG C, send into first order molecular distillator, after processing through first order molecular distillator, the base oil that wherein can be utilized enters light component pans, heavy constituent entrance heavy constituent pans through built-in condenser after condense.
5) filter polishing:
The base oil of above-mentioned light component pans is sent into polishing filter, is filtrated to get that colourity is relatively low, clear lube base oil.
The invention has the advantage that this technique adopts pure physical separation, product quality is stable, non-secondary pollution；Good separating effect, product purity is high；Product can be mixed into the various finished lube such as industrial equipment, vehicular traffic through adding various additives.
Specific embodiment
A kind of waste oil regeneration production process is it is characterised in that its production craft step is:
1) cross and filter metal impurities: by waste oil under conditions of pressure 0.1-0.5mpa, so that waste oil is filtered by magnetic filter, the metal impurities in waste oil are removed；
2) cross filter miscellaneous greatly: will remove metal impurities waste oil under conditions of pressure 0.1-0.5mpa, make removing metal impurities waste oil pass through basket filter, by waste oil large granular impurity remove；
3) blood pressure lowering dehydration: with pump, the waste oil of above-mentioned removing large granular impurity is delivered to preheater and be preheated to after 100-120 DEG C, be re-fed in membrane evaporator, after processing through membrane evaporator；
Lower boiling water therein, gasoline, diesel oil enter in light component pans after plate-type condenser condensation, when the liquid level of light component pans reaches high level, by being pumped into oil water separator, remove moisture therein, reclaim gasoline therein, diesel oil,
The material not evaporated therein then enters in heavy constituent tank；
Purpose is to remove lower boiling for moisture in used oil etc. material and diesel oil, and raw material is carried out with the flash-point being dehydrated pretreatment and improving base oil.
4) molecular distillation purification:
Material in heavy constituent tank is delivered to reheater be heated up to after 300-320 DEG C, sends into first order molecular distillator, after processing through first order molecular distillator.The base oil wherein being utilized enters light component pans after condensing through built-in condenser, and heavy constituent enters heavy constituent pans.Purpose is to separate the base oil in material.
5) filter polishing:
The base oil of above-mentioned light component pans is sent into polishing filter, is filtrated to get that colourity is relatively low, clear lube base oil.
