DETAILED DESCRIPTION

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0036] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so as to describe the embodiments of the present invention described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0037] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0038] See also Figures 1 to 10 As shown, according to an embodiment of the present application, a water vapor recovery device is provided, comprising an induced draft unit 10, a condensation mechanism and a dry cold air guiding unit 50. The induced draft unit 10 is connected to a predetermined wet cooling device to extract water vapor generated by the predetermined wet cooling device. The condensation mechanism comprises a water vapor precooling unit 20, a condensation unit 30, and a condensed water collecting unit 40; wherein the water vapor precooling unit 20 is connected to the induced draft unit 10 to cool the water vapor extracted by the induced draft unit 10, the condensation unit 30 is connected to the water vapor precooling unit 20 to condense the cooled water vapor to obtain condensed water, and the condensed water collecting unit 40 is respectively connected to the induced draft unit 10, the water vapor precooling unit 20 and the condensation unit 30; the dry cold air guiding unit 50 is connected to the condensation unit 30 to guide the dry cold air obtained after condensation by the condensation unit 30 to the predetermined wet cooling device.

[0039] Specifically, the predetermined wet cooling equipment of this embodiment includes but is not limited to wet cooling equipment such as a wet cooling tower. The water vapor generated by the wet cooling equipment can be effectively extracted through the induced draft unit 10, and converted into condensed water by the condensation mechanism. The obtained condensed water can be directly used as water replenishment for the predetermined wet cooling equipment, thereby reducing dependence on external water sources, realizing the recycling of water resources, and improving the efficiency of water resource utilization. While condensing the water vapor by the condensation mechanism to obtain condensed water, dry cold air can also be obtained. The temperature and humidity of the obtained dry cold air are much lower than the ambient temperature and humidity in spring, summer and autumn. The obtained dry cold air is guided and back-blown into the wet cooling equipment through the dry cold air guiding unit 50 of the condensation mechanism, which can improve the refrigeration efficiency of the wet cooling equipment and reduce the demand for fresh dry cold air of the wet cooling equipment, thereby reducing the overall energy consumption and carbon emissions of the wet cooling equipment. The water vapor precooling unit 20 of the condensation mechanism performs preliminary cooling on the extracted water vapor, which helps the condensation unit to perform the condensation operation more efficiently, thereby improving the condensation efficiency and the quality of the condensed water. In addition to being used as make-up water for wet cooling equipment, the recovered condensed water can also be used in other occasions according to actual needs, increasing the versatility and application range of the water vapor recovery device.

[0040] Furthermore, the induced draft unit 10 includes an induced draft channel 11 and an induced draft fan 12. The induced draft channel 11 is provided with an air inlet 111 and an air outlet 112. The air inlet 111 is connected to the exhaust port of the predetermined wet cooling device. The addition of the induced draft fan 12 provides power for the water vapor recovery process. The induced draft fan 12 is arranged at the air outlet 112 of the induced draft channel 11, so that the water vapor generated by the predetermined wet cooling device during refrigeration can enter the induced draft channel 11 through the air inlet 111, and then enter other units from the air outlet 112, ensuring that the water vapor can be efficiently and stably extracted from the exhaust port of the predetermined wet cooling device. In addition, the induced draft fan 12 is arranged at the air outlet 112 to achieve a pre-filtration effect of the water vapor. The water vapor has been decelerated and stabilized to a certain extent before reaching the induced draft fan 12, which helps to reduce the shear force and turbulence effect generated by the high-speed rotation of the induced draft fan 12, thereby further reducing the loss of water vapor.

[0041] Furthermore, the air induced passage 11 is provided with two air outlets 112, and both air outlets 112 are connected to a condensing mechanism. Both air outlets 112 are provided with an air induced fan 12. That is to say, the gas flow in the air induced passage 11 of the present embodiment enters through the air inlet 111, and then is divided into two paths and respectively passes through the two air outlets 112 to enter the unit connected to the two air outlets 112, so as to realize the gas diversion treatment in the air induced passage 11, thereby increasing the recovery efficiency and capacity of the water vapor recovery device. Dividing the water vapor into two paths to enter the condensing mechanism helps to optimize the airflow distribution, reduce airflow congestion and dead corners, thereby improving the heat exchange efficiency, ensuring that each condensing mechanism can obtain a relatively uniform airflow, and helping to ensure the stability and efficiency of the condensation process.

[0042] Furthermore, both sides of the induced air passage 11 in the width direction are provided with a check valve 13, which has a closed state when the predetermined wet cooling device operates normally, and an open state when the water vapor recovery device fails or the induced air volume of the induced air fan 12 is less than the exhaust air volume of the predetermined wet cooling device. Figure 2 The non-return air valve 13 shown includes an air valve plate 131. The non-return air valve 13 can prevent the exhaust of the wet cooling device from being affected when the water vapor recovery device fails or the induced air volume of the induced draft fan 12 is less than the exhaust air volume of the predetermined wet cooling device. When the water vapor recovery device is operating normally, the non-return air valve 13 is closed to prevent the outside air or impurities from entering. When the water vapor recovery device fails or the induced air volume of the induced draft fan 12 is less than the exhaust air volume of the predetermined wet cooling device, the non-return air valve 13 is opened through the air valve plate 131 to prevent the predetermined wet cooling device from overheating or damage due to poor exhaust, thereby ensuring the safe operation of the system. At the same time, the non-return air valve 13 is configured as a mechanical structure with high mechanical reliability, and can be reliably opened in an emergency to provide a necessary exhaust channel.

[0043] Further, the water vapor precooling unit 20 includes a precooling channel 21, a cooling assembly 22 is arranged inside the precooling channel 21, a first heat dissipation assembly 23 and a refrigeration assembly 24 are arranged outside the precooling channel 21, and the refrigeration assembly 24 is respectively connected to the first heat dissipation assembly 23 and the cooling assembly 22. The precooling channel 21 is in communication with the air induction channel 11, and the water vapor enters the precooling channel 21 through the air induction channel 11. The cooling assembly 22 in the precooling channel 21 is connected to the refrigeration assembly 24 outside the precooling channel 21 to reduce its own temperature, so that the water vapor is precooled after passing through the cooling assembly 22, and the temperature of the water vapor is reduced by a certain value before entering the subsequent condensing unit 30, and the water vapor is cooled by the first heat dissipation assembly 23 arranged outside the precooling channel 21, thereby improving the condensation efficiency of the subsequent condensing unit 30, making it easier for the water vapor to be converted into commercial water, and reducing the condensation time and energy consumption.

[0044] Furthermore, the first heat dissipation component 23 includes a heat dissipation base 231 and a plurality of heat dissipation fins 232 integrally arranged with the heat dissipation base 231, the plurality of heat dissipation fins 232 are all located on the same side of the heat dissipation base 231 and are perpendicular to the heat dissipation base 231, and a heat dissipation gap 233 extending in the direction of the pre-cooling channel 21 is provided between the plurality of heat dissipation fins 232; the refrigeration component 24 includes a plurality of semiconductor refrigeration fins 241 arranged parallel to the heat dissipation fins 232, the semiconductor refrigeration fins 241 are connected to a side of the heat dissipation base 231 away from the heat dissipation fins 232, and the number of semiconductor refrigeration fins 241 is less than the number of heat dissipation fins 232; the cooling component 22 includes a cooling base 221 and a plurality of cooling fins 222 integrally arranged with the cooling base 221, the cooling base 221 is connected to the semiconductor refrigeration fins 241, the plurality of cooling fins 222 are all located on the same side of the cooling base 221 and are perpendicular to the cooling base 221, and a cooling gap 223 extending in the direction of the pre-cooling channel 21 is provided between the plurality of cooling fins 222.

[0045] In this embodiment, the heat dissipation base 231 and a plurality of heat sinks 232 are integrally arranged, and the heat sinks 232 are perpendicular to the heat dissipation base 231, and heat dissipation gaps 233 are formed between the heat sinks 232, which effectively increases the heat dissipation area, which is conducive to the rapid dissipation of heat. The extension direction of the heat dissipation gaps 233 is consistent with the direction of the precooling channel 21, which helps to effectively transfer heat along the airflow direction and improves the heat dissipation efficiency. The heat dissipation gaps 233 between the heat sinks 232 not only increase the heat dissipation area, but also form a good air convection channel, which helps to accelerate the dissipation of heat. At the same time, the heat dissipation gaps 233 also help to reduce the thermal interference between the heat sinks 232 and improve the heat dissipation performance.

[0046] The refrigeration component 24 uses a semiconductor refrigeration sheet 241 as a refrigeration element. The semiconductor refrigeration sheet 241 has the advantages of small size and high refrigeration efficiency. The semiconductor refrigeration sheet 241 does not require additional energy-consuming equipment such as a compressor or a circulation pump during the refrigeration process, which helps to reduce the energy consumption of the entire water vapor precooling unit 20 and the cost of the water vapor recovery device. In addition, the semiconductor refrigeration sheet 241 can achieve refrigeration through the Peltier effect, does not require a refrigerant, is environmentally friendly and easy to maintain. The cost of the semiconductor refrigeration sheet 241 is higher than that of the heat sink 232. While being able to achieve a precooling effect, the cost can be reduced by setting the number of semiconductor refrigeration sheets 241 to be less than the number of heat sinks 232.

[0047] The cooling base 221 of the cooling assembly 22 is integrally provided with the cooling fins 222, the cooling fins 222 are perpendicular to the cooling base 221, and cooling gaps 223 are formed between the cooling fins 222, which help to quickly transfer heat from the water vapor to the cooling assembly 22. The extension direction of the cooling gaps 223 is consistent with the precooling channel 21, which is conducive to the transfer of heat along the airflow direction and improves the heat transfer efficiency. The cooling gaps 223 between the cooling fins 222 not only increase the heat transfer area, but also help to form a uniform temperature distribution, help to optimize the precooling effect, and improve the precooling efficiency and stability of the water vapor.

[0048] Further, the condensing unit 30 includes a condensing channel 31, an evaporator 32 is arranged inside the condensing channel 31, and a condenser 33, a throttle 34 and a compressor 35 are arranged outside the condensing channel 31, and the condenser 33, the throttle 34, the evaporator 32 and the compressor 35 are arranged in the same circuit. The condensing unit 30 is based on the principle of the reverse Carnot cycle, which is mainly reflected in resisting the second law of thermodynamics and can stably and controllably provide a low-temperature environment. Based on the reverse Carnot cycle, this embodiment can ensure a higher degree of condensation of water vapor, so that the water vapor recovery efficiency and recovery rate are higher, and the temperature and humidity of the air finally obtained are lower. The specific condensation process is: start the compressor 35, the compressor 35 sucks in and compresses the low-temperature and low-pressure refrigerant in the refrigerant vapor state from the evaporator 32, and the temperature and pressure of the refrigerant vapor in the compression process are increased, and converted into a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant is then transported to the condenser 33, and the refrigerant in the high-pressure state is conducive to releasing heat in the condenser 33. In the condenser 33, the high-temperature and high-pressure gaseous refrigerant exchanges heat with the external air or water. The heat released by the refrigerant is absorbed by the external environment, causing the refrigerant to gradually cool and condense into a liquid state. During the condensation process of the condensing unit 30, the refrigerant changes from a gaseous state to a liquid state, and the temperature and pressure both decrease. After the liquid refrigerant leaves the condenser 33, it enters the throttle 34. The pressure and temperature of the refrigerant are reduced by the throttle 34 so that it reaches appropriate evaporation conditions before entering the evaporator 32. The throttle 34 achieves throttling and pressure reduction by reducing the flow cross-section of the refrigerant, and the refrigerant is cooled due to expansion. The low-temperature and low-pressure gaseous refrigerant flows out of the evaporator 32, reduces the temperature of the water vapor, absorbs heat, and returns to the suction end of the compressor 35 again, and the condensation cycle ends.

[0049] The condenser 33 of this embodiment includes a condenser tube, the throttle 34 includes an expansion valve, and the evaporator 32 includes an evaporation tube, which is connected to the metal aluminum sheet 37, which can effectively improve the heat exchange efficiency and enhance the refrigeration performance of the condensation unit 30. Specifically, Fig. 9The figure shows the control circuit diagram of the condensing unit 30, which adopts a three-phase power supply of 380V, 50Hz, including a first phase line L1, a second phase line L2 and a third phase line L3, N represents the neutral line, and E represents the ground line. The display panel DP is used to display the operating status, fault alarm and other information of the condensing unit 30. The temperature sensor TS is used to detect the temperature of the condensing unit 30 to ensure that it operates within a safe range. The humidity sensor HS is used to detect the humidity of the environment to control the operation of the fan MF or perform other related controls. The pressure switch K1 is used to detect the pressure state of the system. When the pressure exceeds or falls below the set value, the corresponding control logic will be triggered. The drive board DB is the control center of the condensing unit 30. According to the input signal (such as the signal of the temperature sensor TS, the signal of the pressure switch K1, etc.) and the preset control logic, it outputs the corresponding control signal to control the relay, the fan MF and the compressor 35 (i.e. Fig. 9 The phase sequence protector SP is used to detect whether the phase sequence of the three-phase power supply is correct to prevent equipment damage or safety accidents caused by incorrect phase sequence. The first relay KM1 and the second relay KM2 are used to control the start and stop of high-power equipment such as the fan MF and the compressor 35. Among them, the first relay KM1 controls the operation of the fan MF, and the second relay KM2 controls the operation of the compressor 35. The first thermal relay FR1 and the second thermal relay FR2 are used to protect the motor and other equipment from overload, short circuit and other faults. When the motor current exceeds the set value, the first thermal relay FR1 and the second thermal relay FR2 will cut off the three-phase power supply to protect the equipment. The fan MF is used for heat dissipation or ventilation to ensure the normal operation of the condensing unit 30. According to the above control circuit diagram, the control logic of the condensing unit 30 of this embodiment is: when the water vapor recovery device is running, the current output by the three-phase power supply passes through the phase sequence protector SP and is supplied to the drive board DB. The drive board DB judges the operating state according to the input information such as the signal of the temperature sensor TS and the state of the pressure switch K1. When it is necessary to start the fan MF or the compressor 35, the driver board DB outputs a control signal to control the operation of the corresponding equipment through the first relay KM1 or the second relay KM2. During operation, the first thermal relay FR1 and the second thermal relay FR2 monitor the motor current to ensure that the equipment operates within a safe range. If an abnormal situation occurs (such as excessive temperature, abnormal pressure, etc.), the driver board DB will take corresponding protection measures (such as cutting off the power supply, issuing an alarm signal, etc.) according to the preset control logic.

[0050] Further, the condensing unit 30 also includes a second heat dissipation component 36, which is arranged on a side of the condenser 33 away from the condensing channel 31, and the second heat dissipation component 36 includes a heat dissipation fan 361 and a radiator 362. The heat dissipation performance of the condenser 33 is significantly enhanced by the second heat dissipation component 36 integrated with the heat dissipation fan 361 and the radiator 362 in the condensing unit 30. Not only the condensation efficiency is improved, the energy consumption is reduced, and the risk of failure caused by overheating is reduced. Further, the condensate collection unit 40 includes a condensate collection pipe 41, and the condensate collection pipe 41 includes a first water inlet end 411, a second water inlet end 412, a third water inlet end 413 and a water outlet end 414, the first water inlet end 411 is connected to the induced draft unit 10, the second water inlet end 412 is connected to the water vapor precooling unit 20, the third water inlet end 413 is connected to the condensing unit 30, and the water outlet end 414 is connected to a predetermined wet cooling device or a condensate recovery device. Before the water vapor is condensed through the condensation unit 30, a small amount of condensed water will be generated when passing through the induced draft unit 10 and the water vapor precooling unit 20. If the condensed water accumulated in the induced draft unit 10 and the water vapor precooling unit 20 is not discharged in time, it may corrode the inner wall or internal structure of the induced draft channel 11 and the water vapor precooling unit 20, thereby reducing the service life of the water vapor recovery device. By connecting the condensed water collection pipe 41 to the induced draft unit 10, the water vapor precooling unit 20 and the condensation unit 30 respectively, the condensed water in the entire water vapor recovery device can be fully collected, thereby improving the collection efficiency of the water vapor recovery device. When the water outlet 414 of the condensed water collection pipe 41 is connected to the predetermined wet cooling device, the collected condensed water is used for the refrigeration of the predetermined wet cooling device. When the water outlet 414 of the condensed water collection pipe 41 is connected to the condensed water recovery device, the collected condensed water can be used for other purposes, thereby improving the application range of the recovered condensed water.

[0051] Further, the condensed water collecting pipe 41 includes a square pipe or a round pipe. The structure of the square pipe or the round pipe can efficiently collect the condensed water generated from the induced draft unit 10, the water vapor precooling unit 20 and the condensing unit 30 through natural gravity drainage, and prevent the condensed water from flowing back into the induced draft unit 10, the water vapor precooling unit 20 and the condensing unit 30, thereby improving the overall operation efficiency and reliability.

[0052] Furthermore, if Fig.10 As shown, the dry cold air guiding unit 50 is an L-shaped structure. The L-shaped structure can effectively guide and adjust the airflow direction of the dry cold air. When the cold air flows in the channel, the L-shaped curved part can make the airflow produce a certain deflection and buffer, avoiding the airflow directly hitting the pipe wall or other obstacles to generate greater pressure and noise.

[0053] Furthermore, the water vapor recovery device of this embodiment also includes auxiliary equipment 60. If the wet cooling equipment is not sufficient to support the water vapor recovery device, the water vapor recovery device can be supported by the auxiliary equipment 60. The auxiliary equipment 60 adopts a steel frame structure and has a high supporting capacity.

[0054] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the water vapor generated by the predetermined wet cooling equipment (such as the wet cooling equipment) is effectively extracted through the induced draft unit, and the condensation mechanism is used to convert it into condensed water. The condensed water can be directly used as the water replenishment of the predetermined wet cooling equipment, reducing the dependence on external water sources, realizing the recycling of water resources, and improving the efficiency of water resource utilization. The dry cold air obtained during the condensation process has a temperature and humidity far lower than the ambient value. It is guided back to the wet cooling equipment, which can significantly improve the refrigeration efficiency and reduce the demand for fresh dry cold air, thereby reducing overall energy consumption and carbon emissions. The water vapor precooling unit performs preliminary cooling on the extracted water vapor, which helps the condensation unit to perform condensation operations more efficiently, improve the condensation efficiency and the quality of condensed water. At the same time, the condensation unit adopts the reverse Carnot cycle principle and combines efficient heat exchange components to further improve the condensation performance. The second heat dissipation component integrated in the condensation unit significantly enhances the heat dissipation performance of the condenser, improves the condensation efficiency, reduces energy consumption, and reduces the risk of failure caused by overheating. At the same time, the design of the induced draft channel and the water vapor precooling unit also helps to dissipate heat and stabilize the airflow. The condensed water collection unit can fully collect the condensed water in the entire water vapor recovery device, prevent the condensed water from corroding the internal structure of the device, and extend the service life. The L-shaped structure design of the dry cold air guide unit effectively guides and adjusts the airflow direction of the dry cold air, avoids direct impact of the airflow to generate pressure and noise, and improves the airflow utilization efficiency.
