Vacuum oil purifier

Abstract

The invention relates to a vacuum oil purifier, comprising an oil inlet valve, a coarse filter, an oil inlet pump, a heater, a vacuum cylinder, an oil discharging pump, a fine filter, a condenser and a vacuum pump, wherein the oil inlet valve is communicated with the coarse filter, the oil inlet pump, the heater and the vacuum cylinder in sequence; the upper part of the vacuum cylinder is connected with the condenser with the vacuum pump, and the lower part of the vacuum cylinder is connected with the fine filter; and an oil-water separating cylinder is arranged between the heater and the vacuum cylinder and is internally provided with a coalescent filter which is externally connected with a water storage tank with a water discharging electromagnetic valve. The vacuum oil purifier has the advantages that oil liquid containing steam and impurities is purified by adopting the combined action of the oil-water separator and the vacuum cylinder, water, gas and impurities in oil are removed quickly under the state of water cooling and high vacuum, and the demulsification degree is increased, so that the quality of the oil is comprehensively improved, the online operation can be realized, water discharge can be realized without stopping, and the waste oil can reach new-oil standard; and the operation is simple and convenient.

Description

technical field [0001] The invention relates to an oil-water separation device, specifically a vacuum oil purifier for separating moisture, gas and impurity particles in oil, mainly used for steam turbine turbine oil and water turbine turbine oil, and can also be used for Hydraulic oil, refrigeration oil and other lubricating oils that need to remove a large amount of water and achieve precise filtration of impurities. Background technique [0002] During the long-term operation of steam turbines in power plants and power stations, moisture, dust and solid particle impurities will inevitably be mixed into the turbine oil due to various complicated reasons, which will accelerate the oxidation of oil and promote the formation of foam, scale and sludge, causing oil The severe emulsification of the oil makes it difficult to separate oil and water, which reduces the performance of oil lubrication, anti-wear, heat dissipation, dispersion, and cooling. At the same time, it causes ...

Problems solved by technology

Existing vacuum oil purifiers, such as the high-precision vacuum oil purifier disclosed in CN201020510930.9, the oil liquid is directly sent into the vacuum container after passing through the heater, and the water vapor is extracted by the vacuum pump and the condenser, and the vacuum container is discharged. The oil dehydration effect is low, and the purification effect is not ideal, which affects the subsequent use of the oil
