Description

Technical Field

[0001] The invention relates to the technical field of anti-emulsification devices, in particular to an anti-emulsification device for a steam turbine oil tank. Background Art

[0002] Steam turbines are core power equipment that converts steam or gas thermal energy into mechanical energy. They are widely used in power generation, shipbuilding and industrial fields. The oil tank serves as a closed container to store lubricating oil and provide clean lubrication for key components such as bearings and gears. Anti-emulsification is a process of using technical means to prevent lubricating oil from mixing with water to form an unstable emulsion. When the steam turbine is running, steam leakage or condensate intrusion may cause oil-water contact, forming an emulsion under the shear force of high-speed rotating parts. After emulsification, the viscosity of the lubricating oil increases sharply, the lubrication performance decreases and affects heat dissipation, causing metal corrosion, oil film rupture and other problems, which seriously threaten equipment safety; at the same time, the emulsion accelerates oil deterioration and shortens the maintenance cycle. Therefore, oil tank anti-emulsification is one of the core technical requirements to ensure the long-term and stable operation of the steam turbine.

[0003] An existing steam turbine oil water ingress prevention device (Announcement No.: CN219197409U) has at least the following drawbacks:

[0004] In the aforementioned patent, sealant is applied to the contact surface between the air baffle and the turbine oil seal to achieve a preliminary seal, preventing steam from entering the bearing housing through the oil seal, thereby preventing lubricating oil from emulsifying. However, this solution has significant drawbacks in actual operation: the gap between the sealant and the oil seal is susceptible to cyclical stress under high-speed bearing rotation, causing the sealant to distort and form a steam permeation channel, making it difficult to ensure a sealing effect and prevent oil emulsification. Therefore, it is necessary to propose a turbine oil tank anti-emulsification device to address this problem. Summary of the Invention

[0025] It should be noted that, through the support base 1, when the user needs to perform anti-emulsification treatment on the turbine oil to remove moisture, the oil inlet pipe 26 and the oil outlet pipe 27 are connected to the valve and connected to the preset oil inlet pipe and oil outlet pipe, so as to transport the oil to the inside of the dewatering bin 4, and then the valve is closed, and the inside of the dewatering bin 4 is evacuated through the vacuum pump 11 and the connecting pipe 10 to reduce the internal air pressure to increase the evaporation rate of moisture, and then the semiconductor refrigeration plate 7 is started to cool the heat conductor 6, and the heat is conducted through the heat conductor 6 and the radiator 8 is used for heat conduction, and the cooling fan 9 is started to dissipate heat to the radiator 8, and the air flow is discharged through the exhaust hole on the top of the top cover 30.

The electric heating wire 13 is electrically connected to the PLC controller.

[0027] It should be noted that the dewatering tank 4 and the engine oil are heated (below 60 degrees) by the electric heating wire 13, and at the same time, the drive motor 22 is started to drive the rotating frame 21 to rotate. The rotating rotating frame 21 drives the multiple second magnets 25 to rotate. Due to the magnetic attraction between the second magnets 25 and the first magnets 24, the stirring frame 20 is linked to rotate under the support of the fixed tube 29 and the support plate 28, stirring the engine oil, making it evenly heated and accelerating the evaporation of water. In order to control the heating effect, a temperature detector can be installed on the outer wall of the dewatering tank 4, and an air pressure sensor can be installed.

A third circular through hole is provided on the outer circular wall of the dewatering bin 4, and an oil inlet pipe 26 and an oil drain pipe 27 are fixedly connected to the inner circular walls of the third circular through hole at the top and bottom respectively.

[0029] It should be noted that the protective baffle 23 is set up to effectively block the rotating frame 21 to avoid damage caused by accidental touch. At the same time, the aesthetics of the device is improved. Air is taken into the top bin 2 through several air inlet holes 31 and water is drained through the valve 18.

[0030] It should be noted that when the present invention is in use, through the support base 1, when the user needs to perform anti-emulsification treatment on the turbine oil to remove moisture, the oil inlet pipe 26 and the oil outlet pipe 27 are connected to the valve and connected to the preset oil inlet pipe and oil outlet pipe, so that the oil is transported to the inside of the dewatering tank 4, and then the valve is closed, and the inside of the dewatering tank 4 is evacuated through the vacuum pump 11 and the connecting pipe 10 to reduce the internal air pressure to increase the evaporation rate of moisture, and the dewatering tank 4 and the oil are heated (below 60 degrees) by the electric heating wire 13, and at the same time, the drive motor 22 is started to drive the rotating frame 21 to rotate, and the rotating frame 21 rotates. The rack 21 drives the plurality of second magnets 25 to rotate. Due to the magnetic attraction between the second magnets 25 and the first magnets 24, the stirring rack 20 is linked to rotate under the support of the fixed tube 29 and the support plate 28, stirring the engine oil, making it evenly heated and accelerating the evaporation of water.

It should be noted that the stirring frame 20 weighs about 50g, and the magnetic torque can meet its acceleration requirements. The output speed of the drive motor 22 is controlled at 30-50rpm (to avoid high-frequency vibration). The magnet adopts neodymium iron boron permanent magnet (N52 grade), and the surface magnetic field strength is about 1.4 Tesla. The cross-sectional size of the magnet installed in the rectangular groove is 20mm×10mm×5mm (length×width×height). The rectangular groove of the rotating frame 21 is installed with the second magnet 25 (N pole facing outward), and the rectangular groove of the stirring frame 20 is installed with the first magnet 24 (S pole facing outward), forming an attraction of opposite magnetic poles. During production, The gap between the magnets should be minimized. In order to control the heating effect, a temperature detector can be installed on the outer wall of the water removal tank 4, and an air pressure sensor can be installed. The installation method is the existing technology and will not be repeated here. In summary, the device stirs the engine oil through the rotating stirring rack 20, so that the water at the bottom of the engine oil is stirred and quickly vaporized, which improves the dehydration efficiency and shortens the maintenance cycle. Combined with the heating of the electric heating wire 13 and the negative pressure environment, the engine oil dehydration efficiency is significantly improved; at the same time, the rapid liquefaction and collection of water droplets are achieved through components such as the heat conductor 6, the semiconductor refrigeration plate 7, the radiator 8 and the temporary storage tank 17, effectively avoiding the emulsification of the engine oil.
