Abstract
The invention discloses a waste oil regeneration production process, which comprises the following production process steps: A, filtering to remove metal impurities; B, filtering to remove big impurities; C, dehydrating under reduced pressure; D, performing molecular distillation and purification; and E, filtering and polishing. The production process has the advantages that: the process adopts purely physical separation, the quality of the product is stable, and secondary pollution is prevented; 2, the separation effect is desirable, and the purity of the product is high; and 3, the product can be blended by adding various additives into finished lubricating oils for industrial equipment, transport vehicles and the like.
Description
Technical field
This invention relates to the waste oil regeneration production process field.
Background technology
At present, 90% waste oil is purchased with the inferior mixed steam diesel oil of waste oil regeneration production process processing of poor quality or the oil that makes a fire by little refinery, 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, the complex process that has, and production cost is high.
Summary of the invention
Purpose of the present invention is exactly that the oil quality of the regeneration that has for present existing waste oil regeneration production process is good not, the complex process that has, and facility investment is large, the deficiency of production cost height, and a kind of measured waste oil regeneration production process of oil quality of regeneration is provided.
Its production craft step is:
A, mistake filtering metallic impurity: under the condition of pressure 0.1-0.4Mpa, waste oil is filtered by magnetic filter waste oil, the metallic impurity in the waste oil are removed;
B, to cross filtering assorted greatly: will remove the waste oil of metallic impurity under the condition of pressure 0.1-0.4Mpa, and make the waste oil of removing metallic impurity by blue formula strainer, the large granular impurity in the waste oil is removed;
C, step-down dehydration: after will the above-mentioned waste oil of removing large granular impurity delivering to preheater and be preheated to 100-120 ℃ with pump, send into again in the thin-film evaporator, after the thin-film evaporator processing;
Lower boiling water wherein, gasoline, diesel oil enter after the plate-type condenser condensation in the light constituent receiving tank, when the liquid level of light constituent receiving tank reaches high liquid level,
Defeated by pumpDeliver to water-and-oil separator, remove moisture wherein, reclaim wherein gasoline, diesel oil,
The material that is not evaporated wherein then enters in the restructuring minute tank;
D, molecular distillation are purified:
Mass transport to reheater in the restructuring minute tank is heated after 280-320 ℃, send into the one-level molecular still, after the one-level molecular still was processed, the base oil that wherein can be utilized entered the light constituent receiving tank after built-in condenser condenses, recombinated to divide entering restructuring minute receiving tank.
E, filtration polishing:
The base oil of above-mentioned light constituent receiving tank is sent into the polishing filter, filter and to obtain that colourity is lower, the lubricant base of clear.
Advantage of the present invention is:
1, the pure physical sepn of this process using, constant product quality, non-secondary pollution.
2, good separating effect, product purity is high.
3, product can be mixed into the various finished lubes such as industrial equipments, vehicular traffic through adding various additives.

The material that is not evaporated wherein then enters in the restructuring minute tank;
Purpose is that the lower boiling materials such as the moisture in the used oil and diesel oil are removed, to dewater pre-treatment and improve basic oil flash of raw material.
D, molecular distillation are purified:
Mass transport to reheater in the restructuring minute tank is heated after 280-320 ℃, send into the one-level molecular still, after the one-level molecular still is processed.The base oil that wherein can be utilized enters the light constituent receiving tank after built-in condenser condenses, recombinate to divide entering restructuring minute receiving tank.Purpose is that the base oil in the material is separated.
E, filtration polishing:
The base oil of above-mentioned light constituent receiving tank is sent into the polishing filter, filter and to obtain that colourity is lower, the lubricant base of clear.
