Description
Technical field
Present invention relates to a kind of waste oil regeneration production process, and the oil quality particularly regenerated is good, belongs to waste oil regeneration
Production technology field.
Background technology
At present, most of waste oil is purchased by small oil plant and processes inferior mixing with waste oil regeneration production process of poor quality
Petrol and diesel oil or the oil that makes a fire, these illegal small oil plants are the illegal enterprises that country prohibites, and are sternly controlled.It is existing
The oil quality for the regeneration that waste oil regeneration production process has is not good enough, some complex process, and production cost is high.
The content of the invention
The oil quality for the regeneration that the purpose of the present invention has aiming at current existing waste oil regeneration production process is inadequate
Good, some complex process, equipment investment is big, the deficiency of production cost height, and provides a kind of waste oil regeneration production process.
Its production craft step is：
1）Cross and filter out metal impurities：By waste oil under conditions of pressure 0.1-0. 4Mpa, waste oil is set to pass through magnetic filter mistake
Filter, the metal impurities in waste oil are removed；
2）Cross and filter out large granular impurity：By the waste oil for removing metal impurities under conditions of pressure 0.1-0. 4Mpa, make removing golden
Belong to the waste oil of impurity by blue formula filter, the large granular impurity in waste oil is removed；
3）Decompression dehydration：The waste oil of above-mentioned removing large granular impurity is delivered to after preheater is preheated to 100-120 DEG C with pump, then sent
Enter in thin film evaporator, after thin film evaporator is handled；
Lower boiling water therein, gasoline, diesel oil enter in light component pans after plate-type condenser condenses, when light component connects
When being reached high level by the liquid level of tank, by being pumped into oil water separator, moisture therein is removed, reclaims gasoline therein, bavin
Oil, the material therein not evaporated then enter in heavy constituent tank；
4）Molecular distillation purifies：Material in heavy constituent tank is delivered to after reheater is heated up to 280-320 DEG C, is sent into a fraction
Sub- distiller, after the processing of first order molecular distiller, wherein entering after the base oil that can be utilized condenser condensation built in
Light component pans, heavy constituent enter heavy constituent pans；
5）Filtering polishing：The base oils of above-mentioned light component pans is sent into polishing filter, is filtrated to get that colourity is relatively low, clarification
Transparent lube base oil.
It is an advantage of the invention that：This technique uses pure physical separation, and product quality is stable, non-secondary pollution；Separating effect
Good, product purity is high；Product can pass through addition various additives and be mixed into the various finished product lubrications such as industrial equipment, vehicular traffic
Oil.
Embodiment
A kind of waste oil regeneration production process, it is characterised in that its production craft step is：
1）Cross and filter out metal impurities：By waste oil under conditions of pressure 0.1-0. 4Mpa, waste oil is set to pass through magnetic filter mistake
Filter, the metal impurities in waste oil are removed；2）Cross and filter out large granular impurity：The waste oil of metal impurities will be removed in pressure 0.1-0.
Under conditions of 4Mpa, the waste oil of removing metal impurities is set to remove the large granular impurity in waste oil by basket filter；3）Drop
Press-dehydrating：The waste oil of above-mentioned removing large granular impurity is delivered to after preheater is preheated to 100-120 DEG C with pump, is re-fed into film steaming
Send out in device, after thin film evaporator is handled；Lower boiling water therein, gasoline, diesel oil enter light after plate-type condenser condenses
In component pans, when the liquid level of light component pans reaches high level, by being pumped into oil water separator, remove therein
Moisture, reclaims gasoline therein, diesel oil, and the material therein not evaporated then enters in heavy constituent tank；Purpose is by used oil
In the lower boiling material and diesel oil such as moisture remove, raw material is carried out being dehydrated pretreatment and improves the flash-point of base oil；4）Point
Sub- distilation：Material in heavy constituent tank is delivered to after reheater is heated up to 280-320 DEG C, is sent into first order molecular distillation
Device, after the processing of first order molecular distiller.The base oil that can be wherein utilized enters light component after the condenser condensation built in
Pans, heavy constituent enter heavy constituent pans.Purpose is to separate the base oil in material；5）Filtering polishing：Will be upper
The base oil for stating light component pans is sent into polishing filter, is filtrated to get that colourity is relatively low, lube base oil of clear.
