Embodiment Construction

[0026] Implementation of this technique involves two new components: a condenser 5 (usually containing a drain 7 ) installed in the gas phase space of the vacuum tank, and a draining vacuum pump 22 .

[0027] The condenser used in this technology should have the following properties: 1. The temperature of the condenser should be lower than the temperature of the oil. The greater the temperature difference, the better the dehydration effect, but if it freezes, it needs to be defrosted and drained intermittently; 2. Condensate down 3. The drainage device with the condenser can drain the water out of the vacuum tank; 4. It is best to have a fan to promote the rapid flow of water vapor and other gases to the cooling surface of the condenser to improve dehydration Speed; 5. The condensing part is suitable for working in a vacuum environment in a vacuum tank. In order to meet the above conditions, one or more combinations of cold water cooling, compressor refrigeration, semiconducto...

Abstract

The technology and equipment disclosed by the invention are suitable for vacuum dehydration of low-volatile liquid, especially lubricants such as steam turbine oil, gear oil, hydraulic oil, and the like. The conventional liquid vacuum hydration technology is improved by the following steps: using a liquid-discharge vacuum pump that is capable of pumping liquid and gas at the same time, simultaneously exhausting the gas and liquid in the bottom or mid-lower part of a vacuum tank, arranging a condenser on the upper part of the vacuum tank to condense the water steam into water or ice, and finally discharging the water out of the vacuum tank by a water-discharging device.

Description

technical field [0001] The application of the present invention belongs to the technical field of dehydration, degassing and purification of liquids, and specifically relates to a vacuum dehydration method and device for low-volatility liquids, especially suitable for vacuum dehydration of lubricating oils such as steam turbine oil, gear oil, and hydraulic oil Vacuum dehydration compared to other similar low volatility liquids. Background technique [0002] The low-volatility liquid mentioned in this article means that under normal vacuum dehydration working conditions, the water in the liquid can evaporate more into water vapor, while the liquid that needs vacuum dehydration evaporates less, which can be ignored in terms of practicality. The case where the liquid is volatile. [0003] Existing vacuum dehydration methods for low-volatile liquids such as figure 1 As shown, the liquid is generally introduced into a vacuum tank 1 from the liquid inlet 2. Under vacuum conditio...
