The working process of waste engine oil refining machine

1. Heat the heat conduction oil with the heat conduction oil furnace;


2. The heat conducting oil flows into the coil in the distillation reactor and heats the waste engine oil in the distillation reactor;


3. When the waste engine oil is heated to a certain temperature, the reactor is directly heated with fuel. As the temperature increases, the waste engine oil produces oil and flows into the buffer tank. The odorous light components in the waste engine oil can be distilled and collected into the distillation tank.


4. The oil gas from the buffer tank enters the catalytic tower. In the catalytic tower the macromolecular oil gas are broken down into smaller molecules .


5. Oil gas of small molecules enter the cooling system through the catalytic tower and are cooled into liquid oil;

6. After the oil gas steam out, the distillation reactor memory has plenty of hot asphalt, which can be extracted by the asphalt pump.

Two products can be obtained from the waste engine oil refining machine, 80%-85% diesel, 15%-25% asphalt. For the 80-85% diesel oil, you can used it into heavy machinery, gernerator, and boiler. For the 15%-25% asphalt, could be used for paving, or directly sold to asphalt refineries for further refining.



The unique advantages of DOING waste engine oil refining machine

Safety is the most important factor in the whole process. We had successfully researched some safety devices which ensure waste engine oil refining machine work safely.
1. Safety valves, alarming device and the pressure gauge etc.
2. We also have oil-water separator which can stop the oil gas recycle to the reactor, which could avoid the accident.
3. High degree of automation: feed the waste oil, crude oil automatically, to pump oil automatically.

Energy saving:
1. Well sealing for heating system, no gas leak and saving fuel.
2. Continuous feeding with automatic feeder, no gas leak.
3. Recycling of exhaust gas and scientific fire channel design can save energy and thereby reducing costs.


Environmental friendly:
1. The whole process is all sealed, won't release any gas harmful to human and environment.
2. Well water dedusting system can avoid black smoke.
