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, which uses special materials to coalesce the water in the oil into large water droplets to settle The disadvantage of separating water is that it cannot filter emulsified water and micro-water; the other is the vacuum dehydration method using a vacuum pump, which uses a vacuum pump to keep the vacuum tank in a certain vacuum state, so that the water in the oil is continuously vaporized and evaporated. Then it is cooled into water by the condenser and discharged. The disadvantage of this dehydration method is that the performance of the vacuum pump will decrease after working for a period of time, making it difficult to maintain a high working vacuum. In addition, the condensation of steam needs to be condensed by means of a condenser, so the dehydration effect is affected by the condensed water. Effect of Temperature Change

Embodiment 1

[0018] Contaminated oil passes through the one-stage or two-stage turbulence generator in sequence, and at the same time, air is introduced at the air distribution hole of the turbulence generator to form a multi-phase flow oil-water separation system. The detailed description is as follows: the polluted oil is drawn out 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°C through a heating device, and the oil that meets a certain temperature requirement enters the first-stage turbulence generator Mixing with inhaled air; contaminated oil has the property of incompressibility, while air has the property of compressibility. During the mixing process of contaminated oil and air, due to the compressibility of air, compression and expansion will occur In this way, the gas and oil mixture can be fully mixed in a turbulent state, and the rapid phase change of water in oil from liquid to vapor is promoted at a...

Embodiment 2

[0022] In Example 1, due to the introduction of air, the gas content in the oil will increase, which will affect the normal operation of the transformer. At the same time, the air contains a certain humidity, and the residual moisture after filtering is difficult to be lower than 20 ml / kg. Therefore, in order to meet the requirements of transformer oil Oil-water separation, remove the turbulence generator air distribution hole and not introduce air.

[0023] When the first-stage air with orifice plate and the second-stage air with orifice plate of the high-efficiency turbulent-flow phase-change oil-water separation device are removed, although there is no introduction of air, the water vapor and oil flow precipitated by the first-stage turbulent flow generator also form two phases Flow, at the outlet of the first-stage turbulence generator and the second-stage turbulence generator, there will be an expansion and compression pulsation cycle, which will increase the contact area ...

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...
