The boiling point difference between water and oil is large. Under the condition of high vacuum, the boiling point of water drops a lot and the oil is heated so that the water can escape quickly from the oil. Finally the oil will start refined filtration
, to make it qualified oil.
Under the action of vacuum, the original oil will be pulled in from the inlet . And then start primary filtration & heating . The hot oil will become vaporous by injection pipe, and gradually distributed in the reflecting ring, forming three-dimensional multifaceted evaporation . If the vacuum degree is 0.09 MPa in this moment, the boiling point of water will be only 50 ℃, and the oil has been heated and stabilized at 70 ℃, so the water in the oil will escape, oil-water separation.Most of the water vapor enters the condenser and condenses into water droplets.The rest water vapor will be evacuated by a vacuum pump along with the harmful gas in the oil. Then oil will be pumped out , removing particulates and impurities by refined filtration, finally finishing a working cycle. After 2-3 times cycle, water, gas and impurities in the oil will be removed thoroughly , reaching the standard of new oil.
