Description

Technical Field

[0001] The utility model relates to the field of wind power, in particular to a wind turbine gear oil purification and regeneration device. Background Art

[0002] The gearbox is an important component of the doubly-fed wind turbine, which plays a dual role in speed increase and power transmission. Gear oil is the lubricating medium in the gearbox, which plays a role in lubrication and cooling, and can effectively reduce gearbox wear, reduce heat, and extend the service life of the gearbox. However, particles such as iron filings introduced by gearbox wear during operation and high temperatures during operation will cause the gear oil to oxidize and deteriorate, resulting in reduced gear oil viscosity, increased particle size, antioxidant consumption, etc., and further reduce the service life of the oil.

[0003] The gearbox is located at the top of the wind turbine, and it is difficult to take samples or change oil separately, especially for offshore wind farms. Sampling and changing oil are very difficult, and a regular unified oil change strategy is usually adopted to reduce the operation and maintenance burden. However, the operating conditions of each wind turbine are different. When implementing a unified oil change plan, it will be found that some wind turbine oils are seriously aged, while others are of good quality. This not only poses a safety hazard, but also easily causes waste and increases operation and maintenance costs.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to ordinary technicians in this field.

[0008] When the utility model is used, the treatment method can be selected according to the quality of the unit gear oil; when the unit gear oil quality is good, there is no need to regenerate the gear oil online, and it only needs to be put into the online purification circuit. The gear oil flows from the gear oil tank through the oil inlet pipeline assembly, passes through the filter module to complete the coarse filtration and the coalescence dehydration module to complete the fine filtration, and finally the filtered oil is collected into the gear oil tank through the return oil pipeline assembly by the first oil pump.

[0042] It should be noted that the electrical system 23 can control all electric valves in the device, connect all sensors, flow meters and pressure gauges, and control the valve opening according to the received flow and pressure data.

[0043] The filter module 3 includes a first flow meter 31, a first pressure gauge 32, and a magnetic filter 33. The gear oil entering the device through the first electric valve 22 enters the magnetic filter 33 after being detected by the first flow meter 31 and the first pressure gauge 32. The first flow meter 31 and the first pressure gauge 32 can monitor the oil inlet flow and pressure online and transmit the data back to the electrical system 23. The magnetic filter 33 can remove magnetic particles such as iron filings and larger non-magnetic particles in the gear oil, with an average filtration accuracy of 5-80μm.

[0044] The gear oil flowing in from the gear oil tank 1 through the oil inlet pipe 21 is first monitored for flow and pressure by the first flow meter 31 and the first pressure gauge 32 in sequence, and then the magnetic filter 33 removes magnetic metal particles such as iron filings in the gear oil. At the same time, the filter membrane in the magnetic filter 33 intercepts non-magnetic particles with larger particle sizes and impurities such as sludge. The gear oil after coarse filtration by the magnetic filter 33 flows out from the lower end of the magnetic filter 33. The magnetic filter 33 is provided with a pressure sensor and a weight sensor to automatically monitor the pressure at the filter membrane outlet and the weight of the magnetic rod to evaluate the blockage degree of the magnetic filter. In addition, the wear of the gear box can also be judged according to the change trend of the weight of the magnetic rod.

[0045] In this embodiment, the filter module 3 uses a magnetic filter 33 to remove magnetic particles such as iron filings and larger non-magnetic particles in the gear oil according to the characteristics of the pollutants contained in the fan gear oil.

[0046] The coalescing and dehydrating module 4 includes a first pipeline 41, a second electric valve 42, a second flowmeter 43, a second pressure gauge 44, a coalescing filter 45, and a drain valve 46 at the bottom of the coalescing filter 45.

The two ends of the first pipeline 41 are respectively connected to the magnetic filter 33 and the coalescing filter 45. The second flowmeter 43 and the second pressure gauge 44 are connected to the first pipeline 41. The second flowmeter 43 and the second pressure gauge 44 can monitor the inlet flow and pressure online, and the opening of the second electric valve 42 is controlled by the electrical system 23.

The average filtration accuracy is 1-100μm, and the outlet moisture content is less than 15mg / L. The removed moisture is temporarily stored in the water storage chamber of the filter and discharged by the drain valve 46 during maintenance.

[0047] The gear oil after coarse filtration by the magnetic filter 33 enters the coalescence and dehydration module through the second electric valve 42, and is first monitored for flow and pressure by the second flow meter 43 and the second pressure gauge 44, and then enters the coalescence filter for dehydration and filtration. In the coalescence filter, the gear oil is removed from residual particulate matter and other impurities in the first-stage coalescence filter element, and at the same time, the water vapor in the oil coalesces into larger water droplets. The filtered oil flow enters the second-stage separation filter element. During the flow of the oil, the larger water droplets directly enter the separator water storage chamber under the action of gravity, and the remaining water droplets and impurities are finely filtered and removed in the separation filter element. The coalescence filter 45 outlet is provided with a pressure sensor to monitor the outlet pressure of the filter membrane, and a sewage valve 46 is provided at the bottom to facilitate the evaluation of the blockage degree and maintenance of the coalescence filter.

[0048] The first oil pump 5 is installed behind the coalescing and dehydrating module 4 and is connected to the oil return pipeline assembly 6 and the gear oil regeneration module 7, so as to pump the filtered oil back to the gear oil tank or the regeneration circuit.

[0049] The oil return pipeline assembly 6 includes an oil return pipe 61, a fifth electric valve 62, a second sampling pipe 63, and a second sampling valve 64. One end of the oil return pipe 61 is connected to the first oil pump 5, and the other end is connected to the gear oil tank 1. The fifth electric valve 62 is connected to the oil return pipe 61. The second sampling pipe 63 is connected to the oil return pipe 61, and the second sampling valve 64 is connected to the second sampling pipe 63. When the regeneration circuit is not connected, the opening of the fifth electric valve 62 can be regulated by the electrical system 23, and the second sampling valve 64 can be used for sampling and detection.

[0050] The gear oil regeneration module 7 includes a third pipeline 71, a third electric valve 72, a third flow meter 73, a third pressure gauge 74, a regeneration oil tank 75, and a second oil pump 76. One end of the third pipeline 71 is connected to the return oil pipe 61, and the other end is connected to the regeneration oil tank 75. The third electric valve 72, the third flow meter 73, and the third pressure gauge 74 are connected to the third pipeline 71 in sequence. The regeneration oil tank 75 is connected to the second oil pump 76 through a fourth pipeline, and the second oil pump 76 is connected to the regeneration pipeline assembly 8.

[0051] The oil flowing into the regeneration circuit enters the gear oil regeneration module 7 through the third electric valve 72, and enters the regeneration oil tank 75 after the flow and pressure are monitored online by the third flow meter 73 and the third pressure gauge 74. The regeneration oil tank 75 is filled with an adsorbent filler, which can adsorb aging products such as carboxylic acid and sludge in the gear oil to achieve the regeneration of the gear oil. The regenerated gear oil is sent to the regeneration pipeline 81 by the second oil pump 76.

[0052] The regeneration pipeline assembly 8 includes a regeneration pipeline 81, a fourth electric valve 82, a first sampling pipeline 83, and a first sampling valve 84. One end of the regeneration pipeline 81 is connected to the second oil pump 76, and the other end is connected to the gear oil tank 1. The fourth electric valve 82 is connected to the regeneration pipeline 81. The first sampling pipeline 83 is connected to the regeneration pipeline 81, and the first sampling valve 84 is connected to the first sampling pipeline 83. When the regeneration circuit is connected, the gear oil quality can be sampled at the first sampling port.

[0053] In this embodiment, the treatment method can be selected according to the quality of the unit gear oil; when the unit gear oil quality is good, there is no need to regenerate the gear oil online, and it only needs to be put into the online purification circuit. The gear oil flows from the gear oil tank 1 through the oil inlet pipeline assembly 2, and then flows through the filter module 3 to complete the coarse filtration and the coalescence dehydration module 4 to complete the fine filtration. Finally, the filtered oil is collected into the gear oil tank 1 through the return oil pipeline assembly 6 by the first oil pump 5. When the oil quality is poor and needs to be connected to the online regeneration circuit, the return oil pipeline assembly 6 is disconnected, and the gear oil is pressurized by the first oil pump 5 to enter the gear oil regeneration module 7 for regeneration. After regeneration, it is collected into the gear oil tank 1 through the regeneration pipeline assembly 8. The aging products contained in the regeneration process are removed.

[0054] Specifically, the specific purification and regeneration process of this embodiment is as follows:

[0055] When the quality of the unit gear oil is good, such as after replacing new oil, there is no need to regenerate the gear oil online. When it is only put into the online purification circuit, the gear oil enters the purification and regeneration device through the lower oil inlet pipe 21 of the gear oil tank 1 through the first electric valve 22, and flows through the filter module 3 to complete the coarse filtration and the coalescing and dehydration module 4 to complete the fine filtration, and finally flows into the gear oil tank 1 through the return oil pipeline assembly 6.

[0056] Rough filtration process: The oil to be purified flows through the first flow meter 31 and the first pressure gauge 32 in turn. The first flow meter 31 and the first pressure gauge 32 can monitor the gear oil inlet flow and pressure in real time. Then the gear oil is roughly filtered through the magnetic filter 33. The magnetic filter 33 is equipped with a pressure sensor and a weight sensor to monitor the gear oil outlet pressure and the weight of the magnetic rod respectively. When the pressure difference between the outlet pressure and the inlet pressure is greater than 0.15MPa, the electrical system 23 determines that the filter membrane is blocked and prompts the maintenance personnel to perform maintenance through a signal. When the weight sensor indicates that the weight of the magnetic rod has increased abnormally or is overweight, the electrical system 23 determines that the gear box is abnormally worn or the filter is blocked, and prompts maintenance through a signal.

[0057] Fine filtration process: After the coarse filtration, the gear oil enters the coalescence and dehydration module 4 through the second electric valve 42, and the inlet flow and pressure of the filter are monitored in real time through the second flow meter 43 and the second pressure gauge 44. Then the gear oil passes through the coalescence filter 45 to complete the fine filtration to remove smaller particles and water. The coalescence filter 45 is equipped with a pressure sensor to monitor the outlet pressure of the gear oil. When the pressure difference is greater than 0.15MPa, the electrical system 23 determines that the filter membrane is blocked and prompts the maintenance personnel to perform maintenance through a signal.

[0058] When the oil quality is poor and needs to be connected to an online regeneration circuit, the fifth electric valve 62 is closed, the gear oil is pressurized by the first oil pump 5, connected to the gear oil regeneration module 7 through the third electric valve 72 for regeneration, and after regeneration, it is collected into the gear oil tank 1 through the regeneration pipeline assembly 8.

[0059] Regeneration process: The finely filtered gear oil enters the gear oil regeneration module 7 through the third electric valve 72, and the filter inlet flow and pressure are monitored in real time by the third flow meter 73 and the third pressure gauge 74. The gear oil is then sent to the regeneration oil tank 75 to remove the aging products contained therein.

[0060] This embodiment summarizes the characteristics of pollutants contained in the fan gear oil, and specifically uses the filter module 3 to complete the coarse filtration and the coalescing and dehydrating module 4 to complete the fine filtration, so as to achieve the simultaneous removal of particulate matter and water in the oil, and adds the gear oil regeneration module 7 to achieve the preliminary regeneration of the aged oil, which can effectively alleviate the aging problem of the fan gear oil and reduce the oil change cost. The device is connected in parallel to the outside of the gear oil tank 1, and the oil regeneration circuit is connected in parallel with the normal oil return pipeline, which can achieve online purification and regeneration, and is flexible to use and easy to operate.

[0061] Embodiment 2:

[0062] like Figure 1As shown, based on the first embodiment, the fan gear oil online purification and regeneration device in this embodiment also includes an oil leakage collecting tank 9, and the oil leakage collecting tank 9 is located below the gear oil tank 1 and the oil inlet pipeline assembly 2, the filter module 3, the coagulation and dehydration module 4, the first oil pump 5, the return oil pipeline assembly 6, the gear oil regeneration module 7, and the regeneration pipeline assembly 8.

[0063] An oil leakage sensor is arranged in the oil leakage receiving tank 9. When any valve or device leaks oil, the oil falls into the waste oil receiving tank, triggering the oil leakage alarm device, and the electrical system reminds the maintenance personnel through the sound and light alarm.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
