wasted oil purification system

The oil to be treated is from No.5 to No.1500 that is in high, mediate or low viscosity
in movement. This kind of machine is specially used to purify the oil from
cement, chemical and fertilizer production. Sometimes the oil to be treated has
as much as 70% impurities in it, such as aqueous acid, ammonia acid, carbon,
dust-sand-clay, moisture content, etc. The water separated form the oil treated
by this equipment has different colors: the water color can be milk white if the
aqueous acid in it is serious. The color can be blue if the ammonia acid in it
is very much. The color can be white if the oil has been seriously polluted by alkalis.
The waste water from the treated oil has much snow-like floating matter
on it. This equipment takes only the physical principle methods to treat the oil.
It takes no chemical agent for purification. Therefore, the oil treated remains
its original color.
The vacuum oil filter researched and developed by this Institute can treat low and
high viscosity lubricating oil in various kinds. It needs no special conditions
on environment except electricity and waste oil. The waste oil can be treated
everywhere and whenever. The operation is simple and easy. The maintenance for the
equipment is simple and easy, too. And the cost is very little. The electricity
consummation is only 50% of the whole machine in summer and 60% in winter.
When using this equipment to deal with any polluted oil, no chemical agent is needed.
It is purely mechanical and physical purifying methods. Thus, the oil treated
remains the same nature and function.
Wind cooling method is adopted. Therefore, the vapor separated from the polluted
oil can be condensed into liquid in only 2 seconds and discharged completely soon.
Thus, the water source is protected as the water cooling method consumers much
fresh water (it is special suitable for treating the high-viscosity oil and the
water-in-oil that is quite abnormal.)
