Problems solved by technology

When the moisture in the oil reaches a certain level, it will deteriorate the quality of the oil and reduce the viscosity of the oil, thereby reducing the viscosity of the lubricating oil, reducing the thickness of the lubricating oil film, reducing the lubricating performance of the oil, and causing friction between metals; at the same time, water in the oil can also cause Metal corrosion of hydraulic components affects the normal operation of the system
Water and harmful gases in the transformer oil will reduce the insulation performance and affect the safe operation of the transformer.
[0003] At present, there are many kinds of traditional oil-water separation devices at home and abroad, and their working methods are divided into two categories: one is the coalescence dehydration method using water-collecting elements, wh

Example Embodiment

[0017] Example 1:

[0018] The contaminated oil passes through the one-stage or two-stage turbulence generator in turn, and at the same time introduces air into the air distribution hole of the turbulence generator, thereby forming a multi-working fluid, two-phase oil-water separation system. The detailed description is as follows: the contaminated oil is drawn from the oil tank through the oil pump, and the impurities are removed through the filter, and then the oil is heated to 50-60 ℃ through a heating device, and the oil that meets certain temperature requirements enters the first-stage turbulence generator Mixed with the inhaled air; contaminated oil has the property of incompressibility, while air has the property of compressibility. During the process of mixing the contaminated oil and air, compression and expansion will occur due to the compressibility of the air. In this way, the gas and oil mixture can be fully mixed in a turbulent state, which promotes the rapid phase c...

Example Embodiment

[0021] Example 2:

[0022] In Example 1, the introduction of air will increase the air content in the oil and affect the normal operation of the transformer. At the same time, the air contains a certain degree of humidity. The residual moisture after filtration is difficult to be less than 20 ml / kg. Therefore, in order to meet the requirements of transformer oil The oil and water are separated, the air distribution hole of the turbulence generator is removed and no air is introduced.

[0023] When removing the high-efficiency turbulence promoting phase change oil-water separation device, the primary air equipped with orifice plate and the secondary air equipped with orifice plate, although there is no introduction of air, the water vapor and oil flow from the primary turbulence generator also form two phases. Flow, the expansion and compression pulsation cycle will be generated at the outlet of the primary turbulence generator and the secondary turbulence generator, which increase...

Abstract

An efficient torretial flow prompted phase change method for separating the oil from water includes such steps as filtering the polluted industrial oil, heating to 40-70 deg.C, loading in torretial flow generator where water changes from liquid phase to vapour phase, and oil-water separating in the oil-water separator. Its advantages are high effect and speed, and low energy consumption and cost.

Description

Technical field: [0001] The invention belongs to the technical field of industrial oil and relates to an improvement of a method for purifying and separating industrial oil. Background technique: [0002] At present, in many rotating machines, lubricating oil is required to ensure the normal operation of the rotating parts, and the hydraulic system also needs industrial oil to work normally. It is inevitable to contact with water vapor during operation, which will cause water in the oil, and even cause serious emulsification of the oil. Transformer oil also inevitably contains micro-water and harmful gases during work. When the moisture in the oil reaches a certain level, it will deteriorate the quality of the oil and reduce the viscosity of the oil, thereby reducing the viscosity of the lubricating oil, reducing the thickness of the lubricating oil film, reducing the lubricating performance of the oil, and causing friction between metals; at the same time, water in the oil...
