Description

Technical Field

[0001] This utility model relates to the field of heat exchange oil mist filter technology, and in particular to a heat exchange oil mist filter with oil-water separation function. Background Technology

[0002] During the operation of a centrifugal compressor, the movement of the meshing gears and the rotation of the large gear entrain air into the lubricating oil. When the air escapes from the oil, it forms an oil mist in the gearbox and oil tank. It is important for the gearbox and oil tank to expel air smoothly, but the escape of oil mist is not allowed (oil mist released into the atmosphere will cause pollution and also lead to lubricating oil waste).

[0003] However, when the lubricating oil system is running, it heats up and atomizes. At the same time, the oil mist comes into contact with the compressed air supplied to the oil mist filter, which will cause the oil mist to contain a certain amount of water. After the water vapor is intercepted by the oil mist filter element, it will enter the lubrication system in the form of liquid water. The water contained in the lubricating oil will have a great impact on the lubrication system: reduce the lubrication effect, affect the service life of the lubricating oil, and cause corrosion and rust of gears and lubricating oil tank.

[0004] Therefore, it is necessary to propose a heat exchange oil mist filter element with oil-water separation function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a heat exchange oil mist filter element with oil-water separation function to solve the problem that when the lubricating oil system heats up and atomizes after operation, the oil mist comes into contact with the compressed air supplied to the oil mist filter from the outside, which will cause the oil and gas to contain a certain amount of water. After being intercepted by the oil mist filter element, the water vapor will enter the lubrication system in the form of liquid water. The water contained in the lubricating oil will have a great impact on the lubrication system: reducing the lubrication effect, affecting the service life of the lubricating oil, and causing corrosion and rust of gears and lubricating oil tank.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heat exchange oil mist filter element with oil-water separation function, comprising a core body, wherein the core body includes an inner skeleton, and a filter assembly is disposed outside the inner skeleton;

[0007] The inner frame has through-holes in the sidewalls, and the through-holes are in the shape of an inverted triangle.

[0008] The inner side of the inner skeleton is integrally formed with a groove, which is inclined and extends through the upper and lower ends of the inner wall of the inner skeleton.

[0009] Preferably, the mesh has multiple openings.

[0010] Preferably, multiple grooves are provided, and the multiple grooves are evenly distributed.

[0011] Preferably, the filtration assembly includes an inner glass fiber filter membrane, a hydrophilic and oleophobic plant fiber filter membrane, and an outer glass fiber filter membrane, which are distributed sequentially from the inside to the outside.

[0012] Preferably, the thickness of the inner glass fiber filter membrane, the hydrophilic and oleophobic plant fiber filter membrane, and the outer glass fiber filter membrane decreases from coarse to fine.

[0013] Preferably, the outer glass fiber filter membrane is fitted with a sponge sleeve.

[0014] Preferably, the core is provided with a top sleeve at its top end and a bottom sleeve at its bottom end.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model, by setting up an internal skeleton, mesh and groove structure, the mesh structure supports oil mist to condense into liquid, and provides stable support for the oil mist filter element to prevent deformation and failure under pressure. At the same time, it facilitates the downward convergence of oil and its introduction into the groove, avoiding the oil mist from adhering to the mesh surface after condensation and forming resistance that reduces the filter element's throughput. It also helps the condensed oil to slide downward quickly into the recycling system, improving the efficiency of the heat exchange oil mist filter element.

[0017] 2. The grooved inner skeleton serves as the internal heat exchanger of the oil mist filter. The good thermal conductivity of the metal can quickly absorb the heat of the oil mist and conduct it to the outside of the filter through the circulating compressed air. This quickly dissipates the heat of the oil and reduces the operating temperature of the lubricating oil, which can not only improve the lubrication effect but also extend the service life of the lubricating oil.

[0018] 3. By setting up an internal skeleton, an inner glass fiber filter membrane, a hydrophilic and oleophobic plant fiber filter membrane, and an outer glass fiber filter membrane, the oil mist filter element can not only ensure the absolute and effective interception of oil mist and prevent oil mist from escaping, but also use the internal skeleton to form effective protection to prevent the interception surface from being damaged by the pressure of the filter medium, thus preventing filtration failure.

[0023] This utility model provides, for example Figures 1-3 The heat exchange oil mist filter element with oil-water separation function shown includes a core body 1, a top sleeve 2 at the top of the core body 1, and a bottom sleeve 3 at the bottom of the core body 1. The top sleeve 2 and the bottom sleeve 3 are made of stainless steel, and the bottom sleeve 3 is set as a mesh. The intercepted oil mist can pass through the bottom sleeve 3 and flow back for reuse. The top sleeve 2, the core body 1 and the bottom sleeve 3 form a stable structure.

[0024] The core 1 includes an inner frame 4, which is made of stainless steel by stamping. The inner frame 4 is equipped with a filter assembly, which includes an inner glass fiber filter membrane 5, a hydrophilic and oleophobic plant fiber filter membrane 6, and an outer glass fiber filter membrane 7. The inner glass fiber filter membrane 5, the hydrophilic and oleophobic plant fiber filter membrane 6, and the outer glass fiber filter membrane 7 are distributed from the inside to the outside. The outer glass fiber filter membrane 7 is covered with a sponge sleeve 8.

[0025] Both the inner glass fiber filter membrane 5 and the outer glass fiber filter membrane 7 are made of glass fiber filter membrane material.

[0026] The thickness of the inner glass fiber filter membrane 5, the hydrophilic and oleophobic plant fiber filter membrane 6, and the outer glass fiber filter membrane 7 decreases from coarse to fine, and the oil mist gas flows outward from inside the inner skeleton 4 and through the filter assembly.

[0027] An inner glass fiber filter membrane 5 and an outer glass fiber filter membrane 7 are respectively distributed on the inner and outer sides of the hydrophilic and oleophobic plant fiber filter membrane 6. The inner glass fiber filter membrane 5 and the outer glass fiber filter membrane 7 can intercept oil mist but have no water adsorption capacity. The hydrophilic and oleophobic plant fiber filter membrane 6 has strong water absorption and oleophobicity. It can adsorb water vapor and liquid water in the oil mist and intercept liquid and gaseous oil. The water vapor adsorbed by the hydrophilic and oleophobic plant fiber filter membrane 6 gradually leaves the filtration system from the outside of the core 1 under the action of compressed air, preventing water vapor from flowing back into the lubrication system. At the same time, oil mist cannot pass through. The oil mist contained in the gas will be intercepted by the hydrophilic and oleophobic plant fiber filter membrane 6, gather and flow back to the bottom of the core 1 for recycling.

[0028] To change the current situation where conventional oil mist filters can only adsorb oil mist and collect it back, but cannot separate water vapor from the oil mist (the inner glass fiber filter membrane 5 and the outer glass fiber filter membrane 7 can only intercept oil mist, cannot absorb water, and cannot separate oil and water), a hydrophilic and oleophobic plant fiber filter membrane 6 is set in the filter component to adsorb the water vapor contained in the oil mist, and the water vapor adsorbed by the filter paper is discharged through the air discharged in the filter (similar to the principle of air drying clothes).

[0029] By employing multi-layer filtration, classified interception, and precise differentiation of adsorption, the oil mist filter element can efficiently and effectively intercept and return oil mist, adsorb and discharge water vapor, thereby maintaining the good physical and chemical properties of lubricating oil, maintaining good lubrication effect, maintaining the continuous stability of lubricating oil quality, extending the high-quality shelf life (service life) of lubricating oil, and reducing equipment operation and maintenance costs.

[0030] By setting up an inner skeleton 4, an inner glass fiber filter membrane 5, a hydrophilic and oleophobic plant fiber filter membrane 6, and an outer glass fiber filter membrane 7, the oil mist filter element can not only ensure the absolute and effective interception of oil mist and prevent oil mist from escaping, but also use the inner skeleton 4 to form effective protection to prevent the interception surface from being damaged by the pressure of the filter medium, thus preventing filtration failure.

[0031] The inner frame 4 has mesh holes 9 through it on its side wall. There are multiple mesh holes 9, and the mesh holes 9 are in the shape of an inverted triangle. When installing, the corners of the mesh holes 9 should face downwards (the installation direction is marked on the outside of the core 1 during production).

[0032] The inner side of the inner skeleton 4 is integrally formed with grooves 10. Multiple grooves 10 are provided and are evenly distributed. The grooves 10 are inclined and penetrate through the upper and lower ends of the inner wall of the inner skeleton 4, which helps the condensed oil to slide downward quickly into the recycling system.

[0033] An inner skeleton 4 with grooves 10 is added to the inside of the oil mist filter element. The mesh structure support not only helps the oil mist condense into liquid (the principle of spider web condensation), but also provides stable support for the oil mist filter element to prevent it from deforming and failing under pressure.

[0034] The mesh 9 is inverted triangular, which helps the oil to flow downwards and be guided into the groove 10, and prevents oil mist from condensing and adhering to the surface of the mesh 9, forming resistance and reducing the filter element throughput.

[0035] The groove 10 is inclined, which helps the condensed oil to slide downwards quickly into the recycling system.

[0036] The inner skeleton 4 with grooves 10 serves as the internal heat exchanger of the oil mist filter. The good thermal conductivity of the metal can quickly absorb the heat of the oil mist and conduct it to the outside of the filter through the circulating compressed air. This rapid dissipation of oil heat and reduction of lubricating oil operating temperature can not only improve the lubrication effect but also extend the service life of the lubricating oil.
