Evaporation liquid level on, wipe film gasification distillation heavy base oil ingredient；Fail a small amount of heavy base oil ingredient of distillation gasification and big
The liquid film of part residue fraction, into the evaporation liquid level of evaporator middle and lower part on carry out knifing distillation；
Step 4, tower fractionation segmentation: using structured packing fractionating column segmentation two base oil components of weight and a light oil
Component；
Step 5, multi-solvent extracting vacuum suction purification: it is Celsius that the extraction oil of above-mentioned steps with used oil is cooled to 100-150
Degree, then it is down to 60-80 degrees Celsius with water, using multi-solvent extracting, heated direct carclazyte supplements adsorption refining again, in purification
Meanwhile using the water vapour in boiler flue waste heat water- to-water heat exchanger, superheated steam is heated through heat carrier, into base oil refining kettle
Interior air lift light component.
As a further solution of the present invention: flocculant uses sodium hydroxide, and evaporator includes that chimney heat exchanger and heat carry
Body.
As a further solution of the present invention: filler fractionating column includes overhead extraction section, second line of distillation reflux section, second line of distillation extraction
Section, the line reflux section degree that subtracts three and the line extraction section that subtracts three, subtracting three, line extraction pars infrasegmentalis sets interior reflux washing section.
As a further solution of the present invention: the heat carrier in step 5 uses fused salt.
Compared with prior art, the beneficial effects of the present invention are: this method design rationally, technique and easy to operate, by flocculation,
Vacuum heating distillation, wipe film vacuum distillation and etc., used oil can be subjected to recycling and reusing, reach the mesh to economize on resources
, production process safety, there are no pollution to the environment for production technology, and using effect is good.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Embodiment 1
A kind of used oil recycling technique, the specific steps are as follows:
Step 1, vacuum heating flocculation neutralizes and plug: sodium hydrate aqueous solution and anti-scorch antisludging agent, hydrogen being added in used oil
Organic substance in aqueous solution of sodium oxide and in used oil, to reduce corrosion of equipment, anti-scorch antisludging agent can be wiped to avoid slope wall type
Form burnt dirt in film evaporator, used oil enters second line of distillation coil heat exchanger and second line of distillation flows back hot oil heat convection, then into
Enter boiler pipe heat exchanger and flue residue heat heat convection, used oil is warming up to 130-200 degrees Celsius, into decompression evaporator
Raw material water content in oil is extracted in interior flash distillation, gasification, and evaporator extracts gasoline, bavin by chimney heat exchanger and fused salt heat temperature raising, distillation
The components such as oil；
Step 2, vacuum heating distillation: lighter body grouping gasification, oil vapour are directly entered fractionating column and carry out fractionation segmentation；
Step 3, straight wall wipe film vacuum distillation: wiping film vacuum distillation technique using straight wall and the straight wall that matches is wiped film and steamed
Device is sent out, and by the gasification temperature of technique requirement and used oil different component, is steamed using two kinds of different temperatures and two kinds of wiping film differences
Gasification mode is evaporated, the first is the heavy basestock for failing gasification by step 1 and two, squeezes into straight wall using high temperature oil pump
It wipes in film evaporator, heavy basestock is evenly distributed to the evaporation liquid level of evaporator middle and upper part through the effect of evaporator distributor
On, wipe film gasification distillation heavy base oil ingredient；Second of a small amount of heavy base oil ingredient for being the failure to distill gasification and big portion
The liquid film of point residue fraction (colloid, asphalitine), into the evaporation liquid level of evaporator middle and lower part on carry out knifing distillation；
Step 4, tower fractionation segmentation: using structured packing fractionating column segmentation two base oil components of weight and a light oil
Component, filler fractionating column include overhead extraction section, second line of distillation reflux section, second line of distillation extraction section, the line reflux section degree that subtracts three and subtract three
Line produces section, and subtracting three, line extraction pars infrasegmentalis sets interior reflux washing section, washs entrained bubbles drop in the air-flow of rising；
Step 5, multi-solvent extracting vacuum suction purification: it is Celsius that the extraction oil of above-mentioned steps with used oil is cooled to 100-150
Degree, then it is down to 60-80 degrees Celsius with water, using multi-solvent extracting, heated direct carclazyte supplements adsorption refining again, in purification
Meanwhile using the water vapour in boiler flue waste heat water- to-water heat exchanger, superheated steam is heated through heat carrier, into base oil refining kettle
Interior air lift light component improves basic oil flash point and abjection bad smell, and steaming amount and steaming time are chemically examined with base oil reaches mark
Until standard, heating system uses molten heat transfer salt for each heating system heat supply, and heat transfer mitigates, and heating process safety can prevent
