Description
Technical field
Present 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 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 measured waste oil of the oil quality of regeneration
Regenerate production technology.
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 filter out it is big miscellaneous：By the waste oil for removing metal impurities under conditions of pressure 0.1-0. 4Mpa, make removing metal impurities
Waste oil 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, first order molecular distiller is sent into, through one-level
After molecular still processing, wherein enter light component pans after the base oil that can be utilized condenser condensation built in, weight
Component enters 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, lubrication of clear
Oil 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：
！）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 filter out it is big miscellaneous：By the waste oil for removing metal impurities under conditions of pressure 0.1-0. 4Mpa, make removing metal impurities
Waste oil by basket 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 enters in heavy constituent tank；
Purpose is by the lower boiling material such as the moisture in used oil and diesel oil removing, and raw material is carried out to be dehydrated pretreatment and raising
The flash-point of base oil.
4）Molecular distillation purifies：
Material in heavy constituent tank is delivered to after reheater is heated up to 280-320 DEG C, first order molecular distiller is sent into, through one-level
After molecular still processing.The base oil that can be wherein utilized enters light component pans after the condenser condensation built in, weight
Component enters heavy constituent pans.Purpose is to separate the base oil in material.
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, lubrication of clear
Oil base oil.
