Abstract
The invention relates to a waste oil regeneration production technology. The technology comprises the following steps: filtering to remove metal impurities; filtering to remove large impurities; carrying out reduced pressure dewatering; carrying out molecular distilling purification; and filtering, and polishing. The technology adopting single physical separation has the advantages of stable quality of a product, no secondary pollution, good separation effect, and high purity of the product. Various additives can be added to the product to obtain various finished lubricating oils for industrial equipment, traffic vehicles and the like.
Description
Technical field
This invention relates to a kind of waste oil regeneration production process, belongs to waste oil regeneration production process field.
Background technology
At present, most of waste oil is by little refinery the purchase inferior mixed steam diesel oil of waste oil regeneration production process processing of poor quality or the oil that makes a fire, and these illegal little refinerys are illegal enterprises that country prohibites, and are subject to severe control.The oil quality of the regeneration that existing waste oil regeneration production process has is good not, and some complex process, production cost is high.
Summary of the invention
Object of the present invention is exactly that the oil quality of the regeneration had for current existing waste oil regeneration production process is good not, and some complex process, facility investment is large, 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) filtering metallic impurity are crossed: by waste oil under the condition of pressure 0.1-0. 4Mpa, waste oil is filtered by magnetic filter, by the metallic impurity removing in waste oil;
2) filtering is crossed assorted greatly: by the waste oil of removing metallic impurity under the condition of pressure 0.1-0. 4Mpa, make the waste oil of removing metallic impurity by blue formula strainer, by the large granular impurity removing in waste oil;
3) step-down dehydration: the waste oil of above-mentioned removing large granular impurity delivered to preheater preheats to after 100-120 DEG C with pump, then send in thin-film evaporator, after thin-film evaporator process;
Lower boiling water wherein, gasoline, diesel oil enter in light constituent receiving tank after plate-type condenser condensation, when the liquid level of light constituent receiving tank reaches high liquid level, by pump delivery to water-and-oil separator, removing moisture wherein, reclaim gasoline, diesel oil wherein, wherein then do not entered in heavy constituent tank by the material evaporated;
4) molecular distillation is purified:
Mass transport in heavy constituent tank to reheater is heated after 280-320 DEG C, send into first order molecular distiller, after the process of first order molecular distiller, the base oil that wherein can be utilized enters light constituent receiving tank after built-in condenser condenses, and heavy constituent enters heavy constituent receiving tank.
5) polishing is filtered:
The base oil of above-mentioned light constituent receiving tank is sent into polished filter, filters and obtain that colourity is lower, the lubricant base of clear.
Advantage of the present invention is: this technique adopts pure physical sepn, constant product quality, non-secondary pollution; Good separating effect, product purity is high; Product can be passed through the various additive of interpolation and is mixed into the various finished lube such as industrial equipments, vehicular traffic.
Embodiment
A kind of waste oil regeneration production process, is characterized in that its production craft step is:
! ) cross filtering metallic impurity: by waste oil under the condition of pressure 0.1-0. 4Mpa, waste oil is filtered by magnetic filter, by the metallic impurity removing in waste oil;
2) filtering is crossed assorted greatly: by the waste oil of removing metallic impurity under the condition of pressure 0.1-0. 4Mpa, make the waste oil of removing metallic impurity by basket filter, by the large granular impurity removing in waste oil;
3) step-down dehydration: the waste oil of above-mentioned removing large granular impurity delivered to preheater preheats to after 100-120 DEG C with pump, then send in thin-film evaporator, after thin-film evaporator process;
Lower boiling water wherein, gasoline, diesel oil enter in light constituent receiving tank after plate-type condenser condensation, and when the liquid level of light constituent receiving tank reaches high liquid level, by pump delivery to water-and-oil separator, removing moisture wherein, reclaims gasoline, diesel oil wherein,
Wherein then do not entered in heavy constituent tank by the material evaporated;
Object is by the lower boiling materials such as the moisture in used oil and diesel oil removing, carries out dehydration pre-treatment and improve basic oil flash to raw material.
4) molecular distillation is purified:
Mass transport in heavy constituent tank to reheater is heated after 280-320 DEG C, send into first order molecular distiller, after the process of first order molecular distiller.The base oil that wherein can be utilized enters light constituent receiving tank after built-in condenser condenses, and heavy constituent enters heavy constituent receiving tank.Object is separated by the base oil in material.
5) polishing is filtered:
The base oil of above-mentioned light constituent receiving tank is sent into polished filter, filters and obtain that colourity is lower, the lubricant base of clear.
