[0030] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Accordingly, other examples of the exemplary embodiments may have different values.

[0031] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0032] AsFigure 1 As shown, in the prior-art photovoltaic wet thermal cycle system, solution and water are simultaneously introduced into the reaction tank body. The solution refers to heated high-temperature water, and the water refers to normal-temperature water. The waste liquid discharged from the reaction tank body is directly discharged.

[0033] The photovoltaic wet thermal cycle system 100 according to an embodiment of the present invention will be specifically described below with reference to the accompanying drawings.

[0034] As Figures 1 to 4 shown, the photovoltaic wet thermal cycle system 100 according to an embodiment of the present invention includes: a regenerative device 10 and a reaction tank body 20.

[0035] Specifically, the regenerative device 10 has a first water inlet 11, a first water outlet 12, a second water inlet 13, and a second water outlet 14. A first flow path is provided between the first water inlet 11 and the first water outlet 12, and a second flow path is provided between the second water inlet 13 and the second water outlet 14. The first water inlet 11 is communicated with a water source, and the liquid in the first flow path can exchange heat with the liquid in the second flow path. The reaction tank body 20 has a third water inlet 21 and a third water outlet 22. The third water inlet 21 is communicated with the first water outlet 12, and the third water outlet 22 is communicated with the second water inlet 13, so that the waste liquid discharged from the reaction tank body 20 exchanges heat with the liquid provided by the water source in the regenerative device 10.

[0036] In other words, the photovoltaic wet thermal cycle system 100 according to an embodiment of the present invention is mainly composed of a regenerative device 10 and a reaction tank body 20. The silicon wafer can be processed by a wet process in the reaction tank body 20, and the wet process requires a hot water solvent for the reaction.

[0037] A first flow path and a second flow path may be provided in the regenerative device 10. One end of the first flow path is the first water inlet 11, and the other end of the first flow path is the first water outlet 12. One end of the second flow path is the second water inlet 13, and the other end of the second flow path is the second water outlet 14. At least a third water inlet 21 and a third water outlet 22 are provided on the reaction tank body 20.

[0038] The first water inlet 11 can be connected to a water source that can supply cold water, and the cold water here can be normal temperature water. The first water outlet can be connected to the third water inlet 21. Therefore, after the cold water is heated by the heat recovery device 10, it can be introduced into the reaction tank body 20. The second water inlet 13 can be connected to the third water outlet 22, and the solution in the reaction tank body 20 can be discharged through the third water outlet 22. Since the solvent for the wet reaction is hot water, the solution discharged from the reaction tank body 20 still has residual heat. Therefore, the temperature of the solution discharged from the reaction tank body 20 is higher than the temperature of the cold water provided by the water source. By introducing the liquid discharged from the reaction tank body 20 into the heat recovery device 10 through the third water outlet 22 and the second water inlet 13, the liquid discharged from the reaction tank body 20 and the cold water provided by the water source can exchange heat through the first flow path and the second flow path, increasing the temperature of the cold water provided by the water source, so that warm water is discharged from the first water outlet 12.

[0039] In addition, high-temperature water can also be introduced into the reaction tank body 20. Since the temperature of the high-temperature water is difficult to accurately control, in the prior art, cold water is introduced into the reaction tank body 20, and the temperature of the solution in the reaction tank body 20 is controlled by controlling the amount of cold water.

[0040] Thus, for the photovoltaic wet thermal cycle system 100 according to the embodiment of the present invention, the cold water from the water source and the liquid discharged from the reaction tank body 20 are respectively introduced into the heat recovery device 10, and the residual heat of the liquid discharged from the reaction tank body 20 is used to heat the cold water originally introduced into the reaction tank body 20. The heated warm water can still be used to adjust the temperature of the solution in the reaction tank body 20. Since the reaction temperature in the reaction tank body 20 needs to be kept constant, the inflow of warm water can reduce the temperature requirement of the reaction tank body 20 for high-temperature water, thereby realizing the recovery and utilization of heat, with high energy utilization rate and being beneficial to reducing energy consumption.

[0041] According to an embodiment of the present invention, the heat recovery device 10 includes a box body 15 and a heat exchange tube 16. The box body 15 is provided with a first water inlet 11, a first water outlet 12, a second water inlet 13 and a second water outlet 14. A receiving space 151 is defined inside the box body 15. The heat exchange tube 16 is arranged in the receiving space 151, and a liquid passage is formed inside the heat exchange tube 16. One of the receiving space 151 and the liquid passage forms a first flow path, and the other of the receiving space 151 and the liquid passage forms a second flow path.

[0042] In other words, the heat recovery device 10 of this embodiment can mainly be composed of the box body 15 and the heat exchange tube 16. The first water inlet 11, the first water outlet 12, the second water inlet 13 and the second water outlet 14 are all arranged on the box body 15, and the heat exchange tube 16 is accommodated in the receiving space 151 of the box body 15.

[0043] Specifically, the settings of the first water inlet 11, the first water outlet 12, the second water inlet 13, the second water outlet 14, the box body 15, and the heat exchange tube 16 may include but are not limited to the following situations:

[0044] In the first situation, the first water inlet 11 and the first water outlet 12 are communicated with the accommodation space 151 in the box body 15, the second water inlet 13 and the second water outlet 14 are communicated with the heat exchange tube 16, the accommodation space 151 in the box body 15 forms a first flow path, the liquid channel in the heat exchange tube 16 forms a second flow path, cold water is introduced into the box body 15, and waste liquid is introduced into the heat exchange tube 16.

[0045] In the second situation, the first water inlet 11 and the first water outlet 12 are communicated with the heat exchange tube 16, the second water inlet 13 and the second water outlet 14 are communicated with the accommodation space 151 in the box body 15. The liquid channel in the heat exchange tube 16 forms a first flow path, and the accommodation space 151 in the box body 15 forms a second flow path. Cold water is introduced into the heat exchange tube 16, and waste liquid is introduced into the box body 15.

[0046] In the above several situations, heat exchange can be performed between cold water and waste liquid in the heat recovery device 10 to utilize the residual temperature of the waste liquid to heat the cold water.

[0047] In addition, the volume of the accommodation space 151 in the box body 15 is larger than the volume of the liquid channel in the heat exchange tube 16. For the reaction tank body 20, the amount of hot water flowing in + the amount of medium-temperature water = the amount of waste liquid. That is to say, the discharge amount of waste liquid is greater than the amount of medium-temperature water introduced into the reaction tank.

[0048] In the first situation, the flow rate of cold water is greater than the flow rate of waste liquid. Multiple reaction tank bodies 20 can be connected to one heat recovery device 10 to increase the total amount of medium-temperature water required to be provided by the heat recovery device 10, which is beneficial to reducing the number of heat recovery devices.

[0049] In the second situation, the flow rate of cold water is less than the flow rate of waste liquid. Each heat recovery device 10 can better meet the requirements of the corresponding reaction tank body 20. Moreover, since cold water flows in the heat exchange tube 16, it is beneficial to increase the heating time of cold water in the heat recovery device 10, improve the liquid temperature at the first water outlet 12, and improve the energy utilization rate.

[0050] According to some other embodiments of the present invention, the accommodation space 151 is communicated with the first water inlet 11 and the first water outlet 12, and the heat exchange tube 16 is communicated with the second water inlet 13 and the second water outlet 14.

[0051] Specifically, as Figure 4As shown, the first water inlet 11 and the first water outlet 12 can communicate with the accommodation space 151 of the box body 15, cold water can be introduced into the accommodation space 151, the second water inlet 13 and the second water outlet 14 can communicate with the heat exchange tube 16, waste liquid can be introduced into the heat exchange tube 16, and the waste liquid can exchange heat with the cold water through the tube wall of the heat exchange tube 16.

[0052] In this embodiment, introducing cold water into the accommodation space 151 through the first water inlet 11 can increase the inflow of cold water, enabling a single regenerative device 10 to meet the water supply requirements of multiple reaction tanks 20, which is conducive to reducing the number of regenerative devices 10 and lowering the cost of production equipment.

[0053] In some specific embodiments of the present utility model, the number of reaction tanks 20 is multiple, and the third water outlets 22 of the multiple reaction tanks 20 are all communicated with the second water inlet 13 of the regenerative device 10.

[0054] That is to say, a single regenerative device 10 can communicate with multiple reaction tanks 20 and simultaneously meet the requirements of the reaction tanks 20, which is conducive to reducing the number of regenerative devices 10 and lowering the cost of production equipment.

[0055] According to some alternative embodiments of the present utility model, the accommodation space 151 communicates with the second water inlet 13 and the second water outlet 14, and the heat exchange tube 16 communicates with the first water inlet 11 and the first water outlet 12.

[0056] Specifically, as Figure 3 shown, the first water inlet 11 and the first water outlet 12 can communicate with the heat exchange tube 16, waste liquid can be introduced into the accommodation space 151, the second water inlet 13 and the second water outlet 14 can communicate with the accommodation space 151 of the box body 15, cold water can be introduced into the heat exchange tube 16, and the cold water can exchange heat with the waste liquid through the tube wall of the heat exchange tube 16.

[0057] In this embodiment, introducing cold water into the heat exchange tube 16 through the second water inlet 13 can increase the path of the cold water in the regenerative device 10, increase the time the cold water passes through the regenerative device 10, thereby increasing the heat exchange time between the waste liquid and the cold water, making more full use of the heat in the waste liquid, increasing the liquid temperature at the first water outlet 12, and reducing energy consumption.

[0058] According to some other embodiments of the present utility model, the number of reaction tanks 20 and regenerative devices 10 are both multiple, and the multiple reaction tanks 20 and the multiple regenerative devices 10 are arranged in one-to-one correspondence. Therefore, it is conducive to precisely controlling the solution temperature in the corresponding reaction tanks 20 one by one through each heat exchange device, and is not limited by the number of reaction tanks 20, with a more flexible layout.

[0059] In some specific embodiments of the present utility model, the box body 15 extends along the first direction. In the first direction, the first water inlet 11 and the second water outlet 14 are located at one end of the box body 15, and the second water inlet 13 and the first water outlet 12 are located at the other end of the box body 15.

[0060] As Figure 3 and Figure 4 shown, in the first direction, the first water inlet 11 and the first water outlet 12 are distributed at both ends of the box body 15, and the second water inlet 13 and the second water outlet 14 are also distributed at both ends of the box body 15. Moreover, the first water inlet 11 and the second water outlet 14 are located at the same end of the box body 15, and the second water inlet 13 and the first water outlet 12 are located at the same end of the box body 15. Thus, it can be made that the cold water provided by the water source and the waste liquid discharged from the reaction tank body 20 flow in opposite directions within the heat recovery device 10. The low-temperature water and the low-temperature drainage solution are located at one end of the box body 15, and the high-temperature water and the high-temperature drainage solution are located at the other end of the box body 15. Since the smaller the temperature difference between the two heat exchange sides, the higher the heat transfer efficiency, therefore, the photovoltaic wet thermal cycle system 100 of this embodiment is beneficial to improving the heat transfer efficiency and further improving the energy utilization rate.

[0061] Specifically, the heat conduction amount is related to the temperature difference. The larger the temperature difference, the larger the heat conduction amount. The heat conduction Q = kA(dT / dx), where k is the thermal conductivity coefficient, which is a fixed value after the material is determined, A is the contact area of conduction, and dT / dx is the temperature gradient. The temperature gradient when the two liquids enter the liquid in opposite directions is greater than the temperature gradient when the two liquids enter the liquid in the same direction. Therefore, the photovoltaic wet thermal cycle system of this embodiment is beneficial to increasing the heat transfer amount per unit time, that is, improving the heat conduction efficiency, having a better heat conduction effect, and a higher energy utilization rate.

[0062] According to some alternative embodiments of the present utility model, the first water inlet 11 is higher than the first water outlet 12, and / or the second water inlet 13 is higher than the second water outlet 14. Therefore, whether it is the cold water provided by the water source or the waste liquid discharged from the reaction tank body 20, it can pass through the heat recovery device 10 under the action of gravity without the need for an additional water pump for driving, which is beneficial to simplifying the structure of the photovoltaic wet thermal cycle system 100 and reducing the cost of the photovoltaic wet thermal cycle system 100.

[0063] According to other some embodiments of the present utility model, the heat exchange tube 16 includes a plurality of tube segments 17, each tube segment 17 extends along the first direction, and the plurality of tube segments 17 are connected in sequence.

[0064] In other words, the heat exchange tube 16 can be arranged in an S-shaped coil. The heat exchange tube 16 is mainly formed by sequentially connecting a plurality of tube segments 17 end to end. Each tube segment 17 can extend in the first direction, and the plurality of tube segments 17 can be arranged at intervals in a direction perpendicular to the first direction. Thus, it is beneficial to increase the length of the heat exchange tube 16, increase the heat exchange time between the cold water and the waste water in the heat recovery device 10, and improve the energy utilization rate.

[0065] According to some alternative embodiments of the present invention, the reaction tank body 20 further has a fourth water inlet 23, and the photovoltaic wet thermal circulation system 100 further includes a heating device (not shown in the figure). The heating device is respectively connected to the water source and the fourth water inlet 23 and is used for heating the liquid.

[0066] Specifically, high-temperature water can also be introduced into the reaction tank body 20 through the fourth water inlet 23. The high-temperature water can be obtained by heating the cold water provided by the water source through the heating device. When using the heating device to heat the water provided by the water source, considering that the heat will gradually be lost during the transportation of the hot water, the temperature of the heated hot water is slightly higher than the temperature of the wet reaction. At this time, it is difficult to control the temperature of the hot water flowing into the reaction tank body 20 through the fourth water inlet 23. It is necessary to further use the medium-temperature water heated by the heat recovery device 10 in this embodiment for neutralization to control the temperature of the reaction tank body 20 within a suitable range.

[0067] In some specific embodiments of the present invention, the photovoltaic wet thermal circulation system 100 further includes a circulation heater 30. A circulation pipeline is provided between the circulation heater 30 and the reaction tank body 20 and is used for circulating and heating the liquid in the reaction tank body 20.

[0068] Specifically, as Figure 2 shown in the figure, the heater is the circulation heater 30. The reaction tank body 20 may further be provided with a fifth water inlet 24 and a fifth water outlet 25. The fifth water outlet 25 can discharge the aqueous solution to the circulation heater 30. After the aqueous solution is heated by the circulation heater 30, it then flows into the reaction tank body 20 through the fifth water inlet 24. Setting the circulation heater 30 is beneficial to maintaining the constant temperature of the liquid in the reaction tank body 20 and ensuring the normal progress of the wet reaction.

[0069] All in all, for the photovoltaic wet thermal circulation system 100 of the present invention, the cold water from the water source and the liquid discharged from the reaction tank body 20 are respectively introduced into the heat recovery device 10. The residual temperature of the liquid discharged from the reaction tank body 20 is used to heat the cold water originally introduced into the reaction tank body 20. The heated medium-temperature water can still be used to adjust the temperature of the solution in the reaction tank body 20. Since the reaction temperature in the reaction tank body 20 needs to be kept constant, the inflow of the medium-temperature water can reduce the temperature requirement of the reaction tank body 20 for the high-temperature water, thereby realizing the recovery and utilization of heat, with high energy utilization rate and being beneficial to reducing energy consumption.
