(8) purification evaporation: enter in evaporating column after purification heating and be evaporated in vacuo；
(9) refining filtering: it is cooled down after purification evaporation, filter is squeezed into, filters most carclazytes, pass through
Flame filter press carries out secondary filter；
(10) lubricating oil reuses: the lubricating oil after refining filtering be again introduced into equipment carry out using.
A kind of method for purifying and recovering of lubricating oil of the invention, the appropriate time in step (2) can be in 10-40min.
A kind of method for purifying and recovering of lubricating oil of the invention, the proper temperature in step (4) are 360-370 DEG C.
A kind of method for purifying and recovering of lubricating oil of the invention, proper temperature and pressure in step (5) are respectively to be higher than
420 DEG C and 2-8kPa of absolute pressure.
It, can be to money compared with prior art the invention has the benefit that being recycled by above-mentioned setting to lubricating oil
Source is saved, and the waste of resource is reduced, and in removal process, reduces the use of acid, sour gas is reduced in treatment process
Generation, reduce the generation of reluctant acid sludge and sour water, reduce the secondary pollution to environment, use more physics mode
Lubricating oil is recycled, health damage is reduced to operator, improves the safety of its work.
