So the machine is suit for many lines, such as the mine, metallurgy, electric power, transportation, manufactures and so on. Series EFD Anti-Explosion Vacuum Heavy Fuel Oil Purifier is suitable for purifying of oil such as lubricating oil, Diesel oil, heavy fuel oil, turbine oil, hydraulic oil and refrigerator oil used in fields of petrochemical industry, petroleum industry, chemical industry, coal industry, metallurgical industry, power industry, etc. The explosion proof class are ExdBT4Features
1. The machine adopt deeply and precisely FH rectangular filtering system and highly polymeric and sulfur adsorbing material filter. So the machine have strong ability to filter the dirt particles completely and reduce the sulfur content.
2. We adopt the high quality filter materials, which has a good function in anti-corrosive, thermostable, mechanical strength. Especially, the precision of eliminates impurity is high and the service life is long. Also, it has a large volume for storing the impurities.
3. The combination of coalescing separation and vacuum dewatering effectively.
4. The unique degas and dewater system: Using the Stereo-Evaporation technical, which can separate the water and gas from the oil quickly by the Multi-level water-oil separation technology. It can remove the free and dissolved water from the oil thoroughly.
5. It has the back flush system, which can clear impurities automatically.
6. Strong capability of breaking emulsification.
7. Advanced dielectric condensation device
8. This machine installs the new pressure protector, which can control the temperature automatically; also it can drain water on line by the water-separator device. So it is easy to control this machine.
9. The all electric motor is Anti-explosion. The Explosion proof grade is DIIBT4.
10. Adopt Double-infrared fluid level auto-control systems which can control oil inlet and oil outlet automatic.
11. Adopt a trinity of interlocked preventive device.Working Principle
When it starts working, the used oil will be poured into the heater to heat under the vacuum pressure, then the heated oil enter into the primary filter which will eliminate the big impurities, then the oil enter into the vacuum separator, the oil will flow the special radiation device, which make the unit/volume oil to produce a large surface area, lets the pollution oil exposure in the low humidity atmosphere, thus the water, air and gas can be eliminated. The treated vapor and gas form the gaseous mixture becomes the liquid through the water tank and the chiller condensation, then the liquid enters water receiver together, the vacuum extracts the surplus gas.
The oil which is drained away water flow into precision strainer where can exhaust particulates (oil purification). According the quantity of the water content, a whole purification needs many times circulation to drain away the water.

Dehydration (Degas) System
The duplex-stereo vacuum evaporation vessel can enlarge evaporation area efficiently. The heater, being placed on the duplex-stereo vacuum evaporation vessel, becomes an evaporator. Thus the evaporation area of duplex-stereo vacuum evaporation vessel is three times more than that of the common vacuum vessel. This innovation can dehydrate and degas effectively and efficiently.
The optimal structure of the dehydration (degas) system enlarges the surface area of oil exposed to the vacuum system and extends the flowing distance of the oil in the vacuum system. Thus there has sufficient time to remove the moisture and gas from the oil by vaporization.
The filtering materials with variable apertures are made of specialized glass fiber. The sizes of the filtering fiber and aperture dwindle gradually in the different filtering stages. The impurities with different particulate sizes are filtered step by step. The capability of removing particulate matters and impurities is improved greatly by this method.
The filtering system has stable and perfect filtering fineness. The filtering fineness has several grades, including 1, 2,3,4,5,6,10 µm etc. Oil β≥1000 after filter.
The filtering system is equipped with reverse rinse and filth device. It improves the effectiveness of filtering and extends the lifetime of filter awfully.
Electrical Apparatus controlling System
The main components of the electrical apparatus made by Siemens Company ensure the safety of the controlling system. Having several protection systems which will avoid oil ejection, overload and over voltage etc.
Oil heating System
The unique heater structure heats the oil uniformly.
Oil Heater System assures less than 1.0 w/cm². During the heating process, the deterioration of the oil caused by overheating is avoided.
The oil temperature can be adjusted between 0ºC to 100ºC.The heater is controlled manually or automatically. The heater will stop automatically when the oil temperature reaches a certain degree.
Being installed with safety protection devices, the heating system is secure and reliable. The heater will stop operation automatically when the oil volume of inlet is too low to avoid the damages of the heater.
Oil-level Controlling System
The oil-level floating ball and infrared liquid level automatic controller system are installed in the vacuum vessel to control the oil level so as to avoid the oil leaking in the operation.
The new innovation of eliminating froth can avoid the oil ejecting and gushing during the process.
