Problems solved by technology

Nearly a quarter of the upper part of the vacuum degassing tower with this structure is only used to distribute the oil flow, which is not fully utilized, and the flowing oil cannot form a uniform oil film on all the degassing rings, and it is often in the part of the oil near the center of the circle. There is more flow, so the degassing effect is average

Embodiment 1

[0032] exist figure 2 Among them, the vacuum degassing tower has a cylindrical structure, and the insulating oil is injected at a pressure of 0.2Mpa and atomized by the spray atomizer (1) to obtain tiny oil droplets with a diameter of less than 0.2mm. Multiple spray atomizers (1) Arranged in the upper part of the vacuum degassing tower in a ring shape, so as to make the tiny oil droplets fill the upper part of the vacuum degassing tower. The atomized oil droplets fall evenly under the action of gravity. After falling to the degassing ring layer (3), an oil film is formed on the surface of the degassing ring to realize the evaporation of water and gas in the oil. The evaporated water and gas are pumped out of the vacuum degassing tower by the vacuum system, and in the vacuum degassing tower There is an oil mist baffle (2) at the vacuum suction port to ensure that the atomized oil droplets gather and fall without being sucked out by the vacuum system.

Embodiment 2

[0034] exist figure 2 Among them, the vacuum degassing tower has a T-shaped structure, and the insulating oil is injected at a pressure of 0.2Mpa and atomized by the spray atomizer (1) to obtain tiny oil droplets with a diameter of less than 0.2mm. Multiple spray atomizers (1) Arranged in a straight line in the upper cavity of the T-shaped vacuum degassing tower, so that the tiny oil droplets fill the upper cavity of the vacuum degassing tower. The atomized oil droplets fall evenly under the action of gravity. Then converge to the degassing ring layer (3) in the lower cavity, and form an oil film on the surface of the degassing ring to realize the evaporation of water and gas in the oil. The evaporated water and gas are pumped out of the vacuum degassing tower by the vacuum system, There is an oil mist baffle (2) at the vacuum suction port of the vacuum degassing tower to ensure that the atomized oil droplets gather and fall down without being pumped out by the vacuum system...

Abstract

The invention relates to a combined type degassing technology for a vacuum oil filter. A method that atomized spray degassing and film degassing are combined is adopted to increase contact time of insulating oil and vacuum and improve the degassing efficiency.

Description

Technical field [0001] The invention relates to a combined degassing technology for a vacuum oil filter device. Background technique [0002] The vacuum degassing tower is the core equipment of the vacuum oil filter device. The principle of vacuum degassing is to use the different saturated vapor pressures of oil, water and gas under the same external conditions to realize the oil, water and gas in the vacuum chamber. separation. Under a certain vacuum condition, the gas and water with low saturated vapor pressure vaporize and evaporate quickly, and then the vacuum system pumps them out of the vacuum chamber, so as to achieve the purpose of removing water and gas. [0003] At present, the degassing technologies commonly used in vacuum degassing towers include spray atomization degassing and thin film evaporation degassing. Among them, spray atomization degassing is used, such as the vacuum degassing technology adopted by Mitsumi and Kato vacuum oil purifiers in Japan. Afte...
