Vacuum oil purifier's flashing,dehydrate under vacuum
The boiling point of water is proportional to the level of atmospheric pressure, that is, when the pressure increases, the boiling point of water also rises, and when the pressure decreases, the boiling point of water drops accordingly. Under vacuum, the air pressure decreases, so the boiling point of water decreases as the degree of vacuum decreases. Under the vacuum, there is no pressure, so as long as the water exists in the vacuum, it will immediately vaporize. In theory, there is no liquid in the air. But in real life, there is no complete vacuum, so in the vacuum, water will vaporize very quickly, but it is not non-existent. In reality, we can achieve the purpose of reducing the vacuum through the vacuum pump.
The vacuum oil purifier uses the principle of negative pressure flash evaporation. The heated oil is in the negative pressure true fast separator to reduce the boiling point of its moisture and enter the flash vacuum separation tank. At this time, the fluid temperature is higher than the boiling point under the vacuum. Moisture quickly boils and vaporizes in the flash tank and undergoes two-phase separation. The role of the flash tank is to provide space for rapid gasification and vapor-liquid separation of the fluid. Therefore, the vacuum separation of water is related to the temperature and the degree of vacuum, and the volume of the vacuum separator also determines the speed of the separation.
The following is the relationship table between the boiling point of water under vacuum and the degree of vacuum:
