Description

Technical Field

[0001] The invention belongs to the field of thermal power generation, and in particular relates to a highly efficient and energy-saving generator cooling system. Background Art

[0002] Steam turbine generators generate a lot of energy loss during operation, mainly eddy current loss, etc. These power losses are converted into heat inside the motor, causing the generator rotor and stator coil to heat up. In order to protect the insulation material of the generator from reducing the insulation strength due to excessive temperature, and to avoid insulation loss and safety accidents, the heat generated by the loss must be continuously discharged to cool the generator; Existing steam turbine generator cooling is usually carried out by water-hydrogen-hydrogen cooling. However, when the steam turbine generator is cooled by water-hydrogen-hydrogen cooling, the water body that exchanges heat with hydrogen and cooling water usually has scaling, which requires frequent descaling and cleaning of the cooling system. There is a lack of effective descaling measures. At the same time, the hydrogen cooling in the water-hydrogen-hydrogen cooling causes water and hydrogen leakage in the hydrogen heat exchange mechanism due to the vibration of the generator.

In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0018] The present invention provides the following embodiments Example 1 The embodiment of the present invention provides a high-efficiency and energy-saving generator cooling system, such as Figure 1-5 As shown, it comprises: a generator 1, to which a water cooling tube group 2 and a hydrogen cooling tube group 6 are respectively connected, a filter assembly 3 is provided on the water cooling tube group 2, and the filter assembly 3 descales the cooling water through a pre-filter structure 5, and a hydrogen heat exchange assembly 7 is provided on the hydrogen cooling tube group 6, and the hydrogen heat exchange assembly 7 realizes shock absorption of the structure through a floating tube sheet; It also includes a water body monitoring component, which is used to monitor the degree of microbial contamination in circulating water and hot water.

[0019] The working principle and beneficial effects of the above technical solution are as follows: when the generator 1 is cooled, the stator winding of the generator 1 is circulated and cooled by the cooling water in the water cooling tube group 2, and the cooling water removes impurities and scale in the water body when passing through the filter component 3. At the same time, the rotor winding and the stator end of the generator 1 are circulated and cooled by the hydrogen in the hydrogen cooling tube group 6, and the hydrogen in the hydrogen cooling tube group 6 is heat exchanged through the hydrogen heat exchange component 7. The water monitoring component is used to monitor and kill microorganisms in the water body; The present invention utilizes the water-cooling tube group 2 and the hydrogen-cooling tube group 6 to cool the stator winding and the rotor winding of the generator 1. This design can achieve the maximum efficiency of cooling the generator 1 by cooling the rotor winding and the stator winding respectively. At the same time, the design of the filter component 3 can not only filter the impurities and descale the cooling water in the water-cooling tube group 2, but also filter and descale the hot water in the cooling water heat exchanger 24 and the hydrogen heat exchange component 7, thereby avoiding the need for frequent cleaning of the heat exchange structure during long-term operation. In addition, the hydrogen heat exchange component 7 adopts a floating design, which can effectively reduce the impact of the vibration of the generator 1 on the hydrogen heat exchange component 7, and avoid water leakage and hydrogen leakage of the hydrogen heat exchange component 7 due to vibration. At the same time, the design of the water body monitoring component can effectively ensure that the circulation pipeline of the generator 1 is not contaminated or blocked by microorganisms and their secretions, reduce the burden of the filter component 3, and reduce the waste and abuse of reagents.

[0020] Example 2 On the basis of Example 1, the water-cooling pipe group 2 includes an inlet pipe 21 and a return pipe 22, both of which are connected to the top of the generator 1, and the other end of the return pipe 22 is flange-connected to the cooling water storage tank 23, the input end of the inlet pipe 21 is flange-connected to the output end of the cooling water heat exchanger 24, the input end of the cooling water heat exchanger 24 is flange-connected to the output end of the filter assembly 3, the input end of the filter assembly 3 is connected to the output end of the cooling water pump 25 through a pipeline, and the input end of the cooling water pump 25 is connected to the cooling water storage tank 23 through a pipeline.

[0021] The working principle and beneficial effects of the above technical solution are as follows: when the stator of the generator 1 is cooled, the cooling water is pumped out from the cooling water storage tank 23 through the cooling water pump 25, and then input into the filter assembly 3 for filtration and descaling. The purified cooling water enters the cooling water heat exchanger 24 for heat exchange, so that the cooling water is kept at a low temperature and then enters the stator winding of the generator 1 for heat exchange. The cooling water after heat exchange re-enters the cooling water storage tank 23. The present invention realizes a closed circulation of cooling water through the water-cooling pipe group 2. This design can effectively avoid the evaporation loss of cooling water, ensure that the cooling water is not polluted by the external environment, and avoid the circulation water path inside the generator 1 from being blocked. At the same time, the design of the cooling water heat exchanger 24 and the filter assembly 3 can ensure effective cooling of the generator 1.

[0022] Example 3 On the basis of Example 1, the filter assembly 3 includes a filter tank 31, and the two filter tanks 31 are symmetrically installed on the tank rack 32. The output ends of the two filter tanks 31 are flange-connected with the cooling water heat exchanger 24 and the water collecting pipe 33 respectively. The water collecting pipe 33 is flange-connected with the heat exchange input end of the cooling water heat exchanger 24 and the hot water exchange water input end of the hydrogen heat exchange assembly 7 respectively. The input ends of the two filter tanks 31 are flange-connected with the output end of the cooling water pump 25 and the hot water exchange water supply pipe through the pre-filter structure 5. A partition 34 is installed in the two filter tanks 31, and a plurality of connecting ports 35 are penetrated and installed on the partition 34. A plurality of filter core ports 36 are provided on the top of the two filter tanks 31, and a plurality of filter core columns 37 are slidably connected in the filter core ports 36. The two ends of the filter core column 37 are threadedly connected with the filter core port 36 and the connecting port 35 respectively, and a sewage discharge structure 4 is installed on the partition 34.

[0023] The sewage discharge structure 4 includes a sewage outlet pipe 41, one end of which passes through and is fixed at the center of the partition 34, and the other end of the sewage outlet pipe 41 passes through and is fixedly connected to the side of the filter tank 31. A sewage valve 42 is installed at the outlet end of the sewage outlet pipe 41. The bottoms of the two filter tanks 31 are penetrated and rotatably connected with an electric shaft 43, and the working end of the electric shaft 43 is connected to a transfer pipe 44. The top of the transfer pipe 44 is rotatably connected to the sewage outlet pipe 41, and the side of the transfer pipe 44 passes through and is connected with a sewage inlet pipe 45. A sliding sealing port 46 is installed on the sewage inlet pipe 45, and the sliding sealing port 46 is slidably connected to the bottom of the partition 34.

[0024] The pre-filter structure 5 includes an electromagnetic coil 51, which is wound around a pre-filter tube 52. The electromagnetic coil 51 is electrically connected to an electromagnetic control box 53, and the electromagnetic control box 53 is connected to a power source. The pre-filter tube 52 is flange-connected to the filter tank 31 via a pre-filter valve 54.

[0025] The beneficial effects of the above technical solution are as follows: when the filter assembly 3 filters the cooling water and the hot water, the cooling water and the hot water enter the pre-filter tube 52 respectively, and under the control of the electromagnetic control box 53, the electromagnetic coil 51 generates a changing magnetic field acting on the water body, the water body resonates with the magnetic field, and the calcium and magnesium ions and carbonate ions in the water body collide and combine to form crystals. The crystals continue to move along the water body to the pre-filter valve 54 for preliminary filtration, and then the water body enters the filter tank 31 respectively. The water body enters from the bottom of the filter tank 31, and then enters the filter element column 37 from the connection port 35 on the partition 34. After the impurities and fine scale in the water body adhere to the inner surface of the filter element column 37, the water body seeps out from the outside of the filter element column 37, and finally the water body passes through the filter tank 31. The water flows out from the output end. When the impurities and scale on the inner surface of the filter column 37 accumulate to a certain extent, a pressure difference is generated between the inner and outer surfaces of the filter column 37. Then, the electric shaft 43 starts to drive the transfer pipe 44 to rotate. The sewage inlet pipe 45 rotates along with the transfer pipe 44. The sliding seal port 46 gradually overlaps with the connecting port 35. Under the action of the external pressure difference of the filter column 37, the water body flows back into the filter column 37, and carries the impurities and scale into the sewage inlet pipe 45, so as to realize the backwashing of the filter column 37. The water body carries the impurities and scale through the transfer pipe 44 and the sewage outlet pipe 41, and flows out through the sewage valve 42. Then, under the action of the electric shaft 43, the sliding seal port 46 overlaps with each connecting port 35, so as to realize the backwashing of all the filter columns 37. The present invention utilizes the connection port 35 and the filter element port 36 to install the filter element column 37 on the partition 34. This design can facilitate the quick replacement of the filter element column 37. After the filter element column 37 is blocked, it can also be cleaned manually. The design of the two groups of filter tanks 31 can separate the cooling water and the hot water exchange water from each other and maintain the closedness of their respective pipelines. The design of the transfer pipe 44 with two ends respectively connected to the sewage inlet pipe 45 and the sewage outlet pipe 41 for rotation can ensure that each filter element column 37 can be backwashed by rotation in the sewage pipeline, and the independence and sealing of the sewage pipeline can be guaranteed. The design of the sliding sealing port 46 ensures that the filter element column 37 is automatically backwashed under the action of the pressure difference. At the same time, the design of the pre-filter pipe 52 and the electromagnetic coil 51 can effectively precipitate the scale in the water body and filter it after precipitation, avoiding the accumulation of scale in the dead corner of the pipeline due to the excessive length of the pipeline.

[0026] Example 4 On the basis of Example 1, the hydrogen cooling pipe group 6 includes an air intake pipe 61 and an air return pipe 62, both of which are connected to the side of the hydrogen heat exchange component 7, the air return pipe 62 is connected to the input end of the hydrogen purifier 63, the hydrogen purifier 63 is flange-connected to the hydrogen storage tank 64 through the pipe, the air intake pipe 61 is connected to the output end of the hydrogen pump 65, the input end of the hydrogen pump 65 is flange-connected to the hydrogen storage tank 64 through the air pipe, the hydrogen heat exchange component 7 is symmetrically installed on the top of the generator 1, the hydrogen heat exchange component 7 is flange-connected with a cooling water inlet pipe 66 and a cooling water return pipe 67, the other end of the cooling water inlet pipe 66 is flange-connected to the water collecting pipe 33, and the cooling water return pipe 67 is connected to the heat exchange water source.

[0027] The beneficial effects of the above technical solution are as follows: when the rotor and stator ends of the generator 1 are cooled, the hydrogen pump 65 pumps the hydrogen out of the hydrogen storage tank 64, and then enters the hydrogen heat exchange component 7 through the air intake pipe 61. Subsequently, the hydrogen flows into the hydrogen heat exchange component 7 through the inside of the generator 1 for heat exchange. The hot water is filtered by the filter component 3 and then flows into the hydrogen heat exchange component 7 for heat exchange with the hydrogen. The re-cooled hydrogen is again heat exchanged inside the generator 1, and the cycle is repeated until hydrogen needs to be replenished, and it is replenished through the air intake pipe 61. When the hydrogen needs to be discharged, the hydrogen enters the hydrogen purifier 63 through the air return pipe 62 for purification and then flows back into the hydrogen storage tank 64. The present invention uses the air intake pipe 61 and the air return pipe 62 to form a complete hydrogen circuit. This design can ensure the sealing of the hydrogen when entering and exiting the generator 1, and ensure the safe operation of the generator 1.

[0028] Example 5 On the basis of Example 1, the hydrogen heat exchange assembly 7 includes a tube shell 71, a fixed tube sheet 72 is fixedly installed at one end of the tube shell 71, a water exchange pipe head 73 is bolted to the side of the tube shell 71 close to the fixed tube sheet 72, a partition plate 74 is fixedly connected to the water exchange pipe head 73, and the water exchange pipe head 73 is provided with a water inlet 75 and a water outlet 76 on the upper and lower sides of the partition plate 74. The partition plate 74 cooperates with the fixed tube sheet 72. The other end of the tube shell 71 is bolted to an outer head cover 77, a heat exchange component 8 is provided in the tube shell 71, and the tube shell 71 is slidably connected in a cooling box 78, and the cooling box 78 is bolted to the top of the generator 1.

[0029] The heat exchange component 8 includes a plurality of water inlet heat exchange tubes 81 and water outlet heat exchange tubes 82, which are symmetrically arranged in the tube shell 71 from top to bottom. One ends of the plurality of water inlet heat exchange tubes 81 and water outlet heat exchange tubes 82 pass through and are fixed on the fixed tube sheet 72, and the other ends of the plurality of water inlet heat exchange tubes 81 and water outlet heat exchange tubes 82 pass through and are fixed on the floating tube sheet 83. The plurality of water inlet heat exchange tubes 81 and water outlet heat exchange tubes 82 are provided with a plurality of fins 84, and a hoop 85 is nested and connected to the side of the floating tube sheet 83, and a floating head 86 is bolted to the hoop 85.

[0030] The beneficial effects of the above technical solution are as follows: when the hydrogen heat exchange assembly 7 exchanges heat with hydrogen, the hydrogen enters the cooling box 78 and passes through the side of the tube shell 71. At the same time, the hot water flows into the tube shell 71 through the water inlet 75 of the water exchange pipe head 73. Under the action of pressure, the hot water flows into the water inlet heat exchange pipe 81. After reaching the floating head 86, the hot water flows into the water outlet heat exchange pipe 82, and then reaches the water exchange pipe head 73 and flows out from the water outlet 76. When the hot water flows through the water inlet heat exchange pipe 81 and the water outlet heat exchange pipe 82, the fins 84 disturb the hydrogen flow, thereby improving the heat exchange efficiency of the hydrogen. The floating tube sheet 83 allows one end of the water inlet heat exchange pipe 81 and the water outlet heat exchange pipe 82 to move freely in the tube shell 71. The present invention utilizes the partition plate 74 of the water exchange tube head 73 and the fixed tube sheet 72 to divide the hot water into inlet water and return water. This design can ensure that the circulation loop of the hot water is realized in the tube shell 71, and reduce the volume of the tube shell 71. The design of the fin 84 can form turbulence when the hydrogen flows through the inlet heat exchange tube 81 and the outlet heat exchange tube 82 in the tube shell 71, thereby improving the heat exchange efficiency between hydrogen and the hot water. At the same time, the design of the floating tube sheet 83 can enable one end of the inlet heat exchange tube 81 and the outlet heat exchange tube 82 to move freely. This design makes the thermal deformation of the heat exchange tube bundle and the tube shell 71 independent of each other, reduces the vibration caused by thermal stress, and when the tube shell 71 is subjected to external vibration, the free movement of the floating head 86 can absorb part of the vibration energy, thereby protecting the heat exchange tube bundle and the tube shell 71 from damage.

[0031] Example 6 Based on Example 1, the water body monitoring component includes a control module, a data processing module, a detection module and an execution module, and the detection module includes: Pressure sensor: used to detect the pressure in the cooling circulating water and the heat exchange water, and is arranged in the water cooling tube group 2 and the heat exchange tube group; Flow rate sensor: used to detect the flow rate in the cooling circulating water and the heat exchange water, and is arranged in the water cooling tube group 2 and the heat exchange tube group; Temperature sensor: used to detect the temperature of cooling circulating water and heat exchange water, and is arranged in the water cooling tube group 2 and the heat exchange tube group; Oxygen content sensor: used to detect the oxygen content in the cooling circulating water and the heat exchange water, and is arranged in the water cooling tube group 2 and the heat exchange tube group; The first acquisition module is used to detect the organic matter content in the cooling circulating water and the heat exchange water, and is arranged in the water cooling tube group 2 and the heat exchange tube group; The second acquisition module is used to detect the inorganic content in the cooling circulating water and the heat exchange water, and is arranged in the water cooling tube group 2 and the heat exchange tube group; The third acquisition module is used to detect the microbial content in the cooling circulating water and the heat exchange water, and is arranged in the water cooling tube group 2 and the heat exchange tube group; The detection module is electrically connected to the data processing module, the control module is electrically connected to the data processing module and the execution module, and the control module controls the execution module to work based on the data results of the data processing module.

[0032] The control module controls the execution module based on the data results of the data processing module, including the following steps: Step 1: Calculate the water quality prediction coefficient based on the pressure sensor, flow rate sensor, temperature sensor, oxygen content sensor, first acquisition module, second acquisition module and third acquisition module : = ; (1) Among them: is the water quality prediction coefficient, is the pipe diameter of water cooling tube group 2 and heat exchange tube group, For the The third acquisition module's detection value, For the The detection value of the first acquisition module is For the The second acquisition module detects the value, is the compensation coefficient, For the The detection value of the secondary oxygen content sensor, For the The detection value of the secondary pressure sensor, is the fluid density, For the The detection value of the secondary flow rate sensor, For the The detection value of the secondary temperature sensor; Step 2: Based on water quality prediction coefficient Calculate the dosing coefficient of water cooling tube group 2 and heat exchange tube group : = (2); where is the dosage coefficient, is the drug diffusion coefficient, is the drug action coefficient; Step 3: Data processing module according to the dosage coefficient Send a signal to the control module, and the control module controls the execution module to release a specified amount of medicine according to the electrical signal of the data processing module.

[0033] The beneficial effects of the above technical solution are as follows: when the cooling system of the generator 1 is working, since water is used as the cooling and heat exchange medium, it meets the high temperature and high humidity living environment of microorganisms. Therefore, in the cooling system, if the water source itself contains more microorganisms, organic matter or inorganic salts, these substances will promote the reproduction of microorganisms during the circulation process, or the water that is used for a long time in circulation will cause water quality deterioration due to evaporation, concentration and accumulation of pollutants, further aggravating the reproduction of microorganisms. Therefore, it is necessary to monitor the microorganisms in the cooling system to ensure that they are at a low level and the reproduction of microorganisms is relatively rapid. Therefore, according to various monitoring data of the water body, the microorganisms are predicted. When it reaches the predicted threshold, an appropriate amount of agent is added to the cooling system for sterilization operation; The present invention utilizes a control module, a data processing module, a detection module and an execution module to monitor the microorganisms in the water quality of the cooling system, and timely administers medication according to the expected reproduction of the microorganisms. This design can ensure that the amount of microorganisms in the cooling system remains at a low level, avoiding blockage or pollution inside the generator 1, and the design can administer medication according to the amount of microorganisms, avoiding waste and abuse of medication in the water body.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
