Description

Technical Field

[0001] This invention relates to the field of converter valve hall technology, and in particular to a converter valve hall cooling and dehumidification system. Background Technology

[0002] The main function of the converter valve hall in a converter station is to house the converter valves and related equipment. During operation, the converter valves generate a large amount of heat. Generally, a portion of the heat is dissipated by heat exchange between the cooling medium and the converter valve. The cooling equipment outside the valve requires a lot of energy to dissipate the heat from the cooled medium after heat exchange. The remaining heat is dissipated into the air inside the converter valve hall, and the air conditioning system is used to cool the hot air inside the converter valve hall.

[0003] In air conditioning systems, fresh air needs to be introduced to maintain a slightly positive pressure environment. After the fresh air and return air are mixed, they need to be dehumidified before being sent into the valve hall. The air conditioning system simultaneously bears the indoor heat load and humidity load. However, in order to meet the dehumidification requirements of the fresh air, the temperature of the chilled water needs to be set lower than the dew point temperature of the mixed fresh air and return air. But if the chilled water temperature is too low, it will affect the energy efficiency of the chiller unit of the air conditioning system. Moreover, the temperature reduction will cause the relative humidity of the treated air to approach saturation, so the air needs to be heated to reduce the relative humidity before being sent into the room. The air is cooled and then heated again, which requires a lot of energy. Summary of the Invention

[0006] Optionally, the dehumidification module is connected to one side of the heating module along the vertical direction; The switching module includes a rotating wheel made of a moisture-absorbing material. A portion of the rotating wheel is located inside the dehumidification chamber, and another portion is located inside the heating chamber. The rotating wheel rotates about an axis extending in a horizontal direction.

[0007] Optionally, a heat-conducting element is provided inside the heating chamber. The heat-conducting element is located near the second air inlet. The heat-conducting element has an inner cavity. The medium inlet passes through the heating chamber and communicates with the inner cavity. The heat-conducting element is made of a heat-conducting material.

[0008] Optionally, a heater is also provided inside the heating chamber.

[0009] Optionally, the system also includes a controller, wherein the medium conduit is provided with a first temperature sensor, and the controller is electrically connected to the first temperature sensor and the heater.

[0010] Optionally, the dehumidification chamber is equipped with a pre-cooling device, which is located near the first air inlet and is used to cool the humid fresh air input from the first air inlet.

[0011] Optionally, the heating module further includes a medium outlet communicating with the heating chamber; The cooling module also includes a cooling pipe and a cooling device, with the two ends of the cooling pipe connected to the medium outlet and the cooling device, respectively.

[0012] Optionally, the medium pipeline includes a first medium branch pipe and a second medium branch pipe, one end of the first medium branch pipe is used to connect to the converter valve and input the cooling medium after heat exchange with the converter valve, and one end of the second medium branch pipe is connected to the medium inlet; The cooling pipe includes a first cooling branch pipe and a second cooling branch pipe. The two ends of the first cooling branch pipe are respectively connected to the medium outlet and the second cooling branch pipe, and one end of the second cooling branch pipe is connected to the cooling equipment. The cooling module also includes a first three-way valve, the three valve ports of which are respectively connected to the other end of the second cooling branch pipe, the other end of the first medium branch pipe, and the other end of the second medium branch pipe.

[0013] Optionally, the cooling module further includes a return pipe, one end of which is connected to the cooling equipment and the other end of which is connected to the exchange valve.

[0014] Optionally, the second cooling branch pipe includes a first branch pipe and a second branch pipe, one end of the first branch pipe is connected to the valve port of the first three-way valve, the first cooling branch pipe is connected to the first branch pipe, and one end of the second branch pipe is connected to the cooling equipment.

[0015] Compared with the prior art, the cooling and dehumidification system for a converter valve hall according to an embodiment of the present invention has the following advantages: Moist fresh air is introduced into the dehumidification chamber through the first air inlet. When the switching module is switched to the dehumidification chamber, the moisture-absorbing module absorbs water molecules from the moist fresh air in the chamber. The dried fresh air flows to the converter valve hall from the first air outlet, achieving effective dehumidification of the fresh air. Compared with existing technologies, this method does not require lowering the chilled water temperature of the air conditioning chiller unit, thus avoiding affecting the energy efficiency of the air conditioning. Consequently, it also eliminates the need to reheat the cooled air, resulting in lower energy consumption for fresh air dehumidification.

[0016] The cooling medium after heat exchange is fed into the medium pipeline after heat exchange valve, and flows into the heating chamber from the medium inlet. Fresh air entering the heating chamber from the second air inlet absorbs the heat of the cooling medium to form hot air. When the switching module switches to the heating chamber, the water molecules in the switching module absorb the heat of the hot air in the heating chamber and turn into water vapor. The water vapor is then discharged outdoors from the second air outlet.

[0017] This application utilizes the residual heat of the cooling medium after heat exchange to dehumidify the fresh air, and eliminates the need for a separate cooling device to dissipate heat from the cooling medium after heat exchange, thus reducing the energy consumption required by the system.

[0022] like Figure 1As shown, this embodiment of the invention provides a converter valve hall cooling and dehumidification system, including a dehumidification module 1, a heating module 2, a switching module 3, and a cooling module 4; Dehumidification module 1 is provided with a dehumidification chamber 101 and a first air inlet 102 and a first air outlet 103 connected to the dehumidification chamber 101. The first air inlet 102 is used to input humid fresh air, and the first air outlet 103 is used to connect to the converter valve hall. The heating module 2 is provided with a heating chamber 201 and a second air inlet 202, a medium inlet 204 and a second air outlet 203 connected to the heating chamber 201. The second air inlet 202 is used to input fresh air and the second air outlet 203 is connected to the outside. The switching module 3 has a moisture absorption function and can switch between being in the heating chamber 201 and the dehumidification chamber 101; The cooling module 4 includes a medium pipeline 41. One end of the medium pipeline 41 is used to connect to the converter valve and input the cooling medium after heat exchange with the converter valve. The other end of the medium pipeline 41 is connected to the medium inlet 204.

[0023] In this embodiment, humid fresh air is introduced into the dehumidification chamber 101 through the first air inlet 102. When the switching module 3 switches to the dehumidification chamber 101, the switching module 3 with moisture absorption function absorbs water molecules from the humid fresh air in the dehumidification chamber 101. The dried fresh air flows from the first air outlet 103 to the converter valve hall, achieving effective dehumidification of the fresh air. Compared with the prior art, it does not require lowering the chilled water temperature of the air conditioning chiller unit, thus avoiding affecting the energy efficiency of the air conditioning. Furthermore, it does not require reheating the cooled air, resulting in lower energy consumption for fresh air dehumidification.

[0024] The cooling medium after heat exchange is fed into the medium pipeline 41, and flows into the heating chamber 201 from the medium inlet 204. Fresh air entering the heating chamber 201 from the second air inlet 202 absorbs the heat of the cooling medium to form hot air. When the switching module 3 switches to the heating chamber 201, the water molecules in the switching module 3 absorb the heat of the hot air in the heating chamber 201 and turn into water vapor. The water vapor is then discharged outdoors from the second air outlet 203.

[0025] This embodiment utilizes the residual heat of the cooling medium after heat exchange to dehumidify the fresh air, and there is no need to install a separate cooling device to dissipate heat from the cooling medium after heat exchange, thus reducing the energy consumption required by the system.

[0026] like Figure 1 As shown, in this embodiment, the dehumidification module 1 is further connected to one side of the heating module 2 along the vertical direction; The switching module 3 includes a rotating wheel 31 made of a moisture-absorbing material. Part of the rotating wheel 31 is located in the dehumidification chamber 101 and another part is located in the heating chamber 201. The rotating wheel 31 rotates about an axis that extends in the horizontal direction.

[0027] In this embodiment, the impeller 31 rotates about an axis extending in the horizontal direction. When a part of the impeller 31, which uses a moisture-absorbing material, rotates to the dehumidification chamber 101, it can absorb water molecules from the humid fresh air. When the part rotates to the heating chamber 201, the water molecules attached to the part absorb the heat of the hot air and turn into water vapor, and the impeller 31 is regenerated.

[0028] Therefore, as the rotor 31 rotates, each position of the rotor 31 can switch between being in the dehumidification chamber 101 and the heating chamber 201, thereby realizing the circulation of fresh air dehumidification and water evaporation by the rotor 31.

[0029] Furthermore, gas filters 5 are installed in both the dehumidification chamber 101 near the first air inlet 102 and near the first air outlet 103, and a gas filter 5 is installed in the heating chamber 201 near the second air inlet 202. A fan 6 is installed in the dehumidification chamber 101 with the gas filter 5 facing away from the first air outlet 103, and a fan 6 is installed in the heating chamber 201 near the second air outlet 203.

[0030] like Figure 1 As shown, in this embodiment, a heat-conducting element 21 is further provided inside the heating chamber 201. The heat-conducting element 21 is located near the second air inlet 202. The heat-conducting element 21 has an inner cavity. The medium inlet 204 penetrates into the heating chamber 201 and communicates with the inner cavity. The heat-conducting element 21 is made of a heat-conducting material.

[0031] In this embodiment, the cooling medium after heat exchange has a high heat value, which is input from the medium inlet 204 into the inner cavity of the heat conductor 21. The heat conductor 21 is made of a heat-conducting material and can conduct the heat in the inner cavity to the outside.

[0032] When fresh air enters the heating chamber 201 from the second air inlet 202, it can absorb the heat from the heat-conducting component 21 near the second air inlet 202 to form hot air. Then, when the hot air passes through the switching module 3 in the heating chamber 201, the water molecules in the switching module 3 can absorb the heat of the hot air and turn into water vapor. The water vapor is discharged outdoors from the second air outlet 203 along with the hot air.

[0033] The heat-conducting component 21 is a coil.

[0034] like Figure 1 As shown, in this embodiment, a heater 22 is further provided inside the heating chamber 201.

[0035] In this embodiment, a heater 22 is provided in the heating chamber 201, which can increase the temperature of the hot air in the heating chamber 201, increase the temperature difference between the hot air and water molecules, improve the heat transfer efficiency between the hot air and water molecules, and enable the water molecules of the switching module 3 to be converted into water vapor more quickly, thereby achieving rapid dehumidification.

[0036] like Figure 1 As shown, in this embodiment, a controller is further included. The medium pipeline 41 is provided with a first temperature sensor 42, and the controller is electrically connected to the first temperature sensor 42 and the heater 22.

[0037] In this embodiment, the first temperature sensor 42 detects the temperature of the cooling medium flowing in the medium pipe 41. When the detected temperature is lower than the preset value, the first temperature sensor 42 sends a signal to the controller, and the controller controls the heater 22 to start or increase its power.

[0038] Furthermore, the output end of the rotating shaft motor is connected to the shaft of the rotating wheel 31, and the controller is electrically connected to the rotating shaft motor. When a portion of the rotating wheel 31 absorbs water molecules to a saturated state, the rotating wheel 31 is driven to rotate, allowing that portion of the rotating wheel 31 to enter the heating chamber 201.

[0039] like Figure 1 As shown, in this embodiment, a pre-cooling device 12 is further provided in the dehumidification chamber 101. The pre-cooling device 12 is located near the first air inlet 102 and is used to cool down the humid fresh air input from the first air inlet 102.

[0040] In this embodiment, if the temperature of the fresh air entering the dehumidification chamber 101 from the first air inlet 102 is high, the pre-cooling device 12 is activated to cool the fresh air, increase the relative humidity of the fresh air, and improve the dehumidification efficiency.

[0041] The precooling device 12 is a coil connected to the air conditioning cold source.

[0042] like Figure 1 As shown, in this embodiment, the heating module 2 is further provided with a medium outlet 205 that communicates with the heating chamber 201; The cooling module 4 also includes a cooling pipe 43 and a cooling device 44, with the two ends of the cooling pipe 43 connected to the medium outlet 205 and the cooling device 44, respectively.

[0043] In this embodiment, if the cooling medium fails to exchange heat sufficiently in the heating chamber 201, the cooling medium can be discharged from the heating chamber 201 through the medium outlet 205 and flow into the cooling pipe 43, where it will be further cooled by the cooling device 44.

[0044] To prevent the cooling medium from accumulating in the heating chamber 201, a medium outlet 205 is provided to discharge the cooling medium from the heating chamber 201 in a timely manner.

[0045] The heat from the cooling medium after heat exchange with the heat exchange valve is first used to heat the fresh air, and then the cooling device 44 is used to dissipate heat. This can more fully remove the heat from the cooling medium and reduce the energy consumption required by the cooling device 44 compared to the prior art, thus reducing fresh water consumption and noise impact.

[0046] like Figure 1-2 As shown, in this embodiment, the medium pipeline 41 further includes a first medium branch pipe 411 and a second medium branch pipe 412. One end of the first medium branch pipe 411 is used to connect to the converter valve and input the cooling medium after heat exchange with the converter valve. One end of the second medium branch pipe 412 is connected to the medium inlet 204. The cooling pipe 43 includes a first cooling branch pipe 431 and a second cooling branch pipe 432. The two ends of the first cooling branch pipe 431 are respectively connected to the medium outlet 205 and the second cooling branch pipe 432, and one end of the second cooling branch pipe 432 is connected to the cooling equipment 44. The cooling module 4 also includes a first three-way valve 45, the three valve ports of which are respectively connected to the other end of the second cooling branch pipe 432, the other end of the first medium branch pipe 411, and the other end of the second medium branch pipe 412.

[0047] In this embodiment, by controlling the opening and closing of the three valve ports of the first three-way valve 45, the flow direction of the cooling medium can be changed, allowing the cooling medium to flow into the second medium branch pipe 412 and enter the heating chamber 201, or to flow into the second cooling branch pipe 432 and enter the cooling equipment 44, thus achieving the diversion of the cooling medium. Alternatively, the amount of cooling medium flowing into different pipes can be adjusted by adjusting the opening of the valve ports to meet the requirements.

[0048] Furthermore, the first medium branch pipe 411 is connected to a degassing device 7, which can release air bubbles after the cooling medium is processed by the degassing device.

[0049] Furthermore, the first medium branch pipe 411 is equipped with a circulation pump 10, which increases the pressure of the cooling medium in the pipe, which is conducive to the smooth flow of the cooling medium in the pipe.

[0050] Furthermore, the first cooling branch pipe 431 is equipped with a butterfly valve 11. When it is necessary to inspect or clean the heat-conducting component 21, the butterfly valve 11 can be closed without affecting the operation of the subsequent pipeline.

[0051] like Figure 1 As shown, in this embodiment, the cooling module 4 further includes a return pipe 50, one end of which is connected to the cooling device 44 and the other end is used to connect to the converter valve.

[0052] In this embodiment, the cooling medium, after being cooled by the cooling device 44, can be returned to the converter valve through the return pipe 50, and then exchange heat with the converter valve to realize the recycling of the cooling medium.

[0053] like Figure 1-2 As shown, in this embodiment, the second cooling branch pipe 432 further includes a first branch pipe 4321 and a second branch pipe 4322. One end of the first branch pipe 4321 is connected to the valve port of the first three-way valve 45, the first cooling branch pipe 431 is connected to the first branch pipe 4321, and one end of the second branch pipe 4322 is connected to the cooling device 44. The cooling module 4 also includes a diversion pipe 46 and a second three-way valve 47. The three valve ports of the second three-way valve 47 are respectively the other end of the first branch pipe 4321, the other end of the second branch pipe 4322, and one end of the diversion pipe 46. The other end of the diversion pipe 46 is connected to the return pipe 50.

[0054] In this embodiment, by controlling the opening and closing of the three valve ports of the second three-way valve 47, the flow direction of the cooling medium can be changed, allowing the cooling medium to flow into the second branch pipe 4322 and enter the cooling equipment 44 for cooling, or allowing the cooling medium to flow into the second cooling branch pipe 432 of the diversion pipe 46 and directly return to the converter valve without passing through the cooling equipment 44.

[0055] Furthermore, the return pipe 50 is equipped with a media filter 8, which can filter the cooling medium passing through the return pipe 50 to prevent impurities in the cooling medium from flowing back to the converter valve. The media filter 8 is located in a section after the return pipe is connected to the diversion pipe.

[0056] Furthermore, the return pipe 50 is connected to a comprehensive treatment device 9 before the media filter 8. The comprehensive treatment device 9 is connected to the section of the first media branch pipe 411 between the degassing device 7 and the circulating pump 10 via a pipe. The comprehensive treatment device 9 integrates three major functions: deionization, pressure regulation, and water replenishment. It can process the cooling medium and then circulate it back to the first media branch pipe 411.

[0057] Furthermore, the first branch pipe 4321 is equipped with a second temperature sensor 48, which is located on the section after the first branch pipe 4321 connects to the first cooling branch pipe 431. The controller is electrically connected to the second temperature sensor 48 and the second three-way valve 47. When the second temperature sensor 48 detects that the temperature of the cooling medium in the first branch pipe 4321 is lower than a preset value, it indicates that cooling equipment 44 is not needed for cooling. The controller controls the opening and closing of the three valves of the second three-way valve 47, allowing the cooling medium to flow directly into the branch pipe 46 and then into the return pipe 50 to return to the switching valve. Alternatively, the amount of cooling medium flowing into different pipes can be adjusted by adjusting the valve opening to meet the requirements.

[0058] Furthermore, the return pipe 50 is equipped with a third temperature sensor 49, which is located near the end of the return pipe 50 that connects to the converter valve. The controller is electrically connected to the third temperature sensor 49. The third temperature sensor 49 detects the temperature of the cooling medium in the return pipe and can determine whether the temperature of the cooling medium that is about to return to the converter valve has dropped to a preset value.

[0059] The working process of this invention is as follows: Moist fresh air is introduced into the dehumidification chamber 101 through the first air inlet 102. At this time, when the switching module 3 is switched to the dehumidification chamber 101, the switching module 3 with moisture absorption function absorbs water molecules from the moist fresh air in the dehumidification chamber 101. The dried fresh air flows from the first air outlet 103 to the converter valve hall, realizing effective dehumidification of the fresh air. Compared with the prior art, it is not necessary to lower the chilled water temperature of the air conditioning chiller unit, thus avoiding affecting the energy efficiency of the air conditioning. Furthermore, it is not necessary to reheat the cooled air, and the energy consumption required for fresh air dehumidification is lower.

[0060] The cooling medium after heat exchange is fed into the medium pipeline 41, and flows into the heating chamber 201 from the medium inlet 204. Fresh air entering the heating chamber 201 from the second air inlet 202 absorbs the heat of the cooling medium to form hot air. When the switching module 3 switches to the heating chamber 201, the water molecules in the switching module 3 absorb the heat of the hot air in the heating chamber 201 and turn into water vapor. The water vapor is then discharged outdoors from the second air outlet 203.

[0061] In summary, the embodiments of the present invention provide a converter valve hall cooling and dehumidification system that can achieve fresh air dehumidification and heat dissipation of the cooling medium after heat exchange, thereby reducing the energy consumption required by the system.

[0062] The above description is only an optional embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
