This application relates to a seawater temperature difference energy (TEE) water generation device, specifically in the field of freshwater collection. It includes an insulated tank, a pumping insulated pipe connected to the inlet end of the insulated tank and extending into seawater, a conveying insulated pipe connected to the outlet end of the insulated tank, a condenser pipe connected to the end of the conveying insulated pipe furthest from the insulated tank, and a return pipe connected to the end of the condenser pipe furthest from the conveying insulated pipe. A pump is installed on the conveying insulated pipe, and a collection tank for collecting condensate is located below the condenser pipe. This application uses a pump to sequentially pass seawater through the pumping insulated pipe, the insulated tank, and the conveying insulated pipe to the condenser pipe.

Description

Technical Field

[0001] This application relates to the field of freshwater collection, and in particular to seawater thermal energy conversion devices. Background Technology

[0002] Freshwater is defined as water with a salinity of less than 0.5 g / L. The total amount of water on Earth is 1.4 billion cubic kilometers. While there is a vast amount of water on Earth, freshwater reserves account for only 2.53% of the global total. Humans typically drink freshwater. Currently, humans can directly utilize only groundwater, lake freshwater, and river water, which together account for approximately 0.77% of the Earth's total water.

[0003] Chinese Patent CN207361823U discloses a seawater desalination device, including a shell and a jet pump. The shell contains a condensation chamber and an evaporation chamber. The condensation chamber contains a condenser and is equipped with a water supply pipe, a condensate pipe, and a vacuum pipe. The vacuum pipe is connected to the jet pump, and the water supply pipe is connected to the evaporation chamber. The evaporation chamber contains an evaporator with a cylinder liner water inlet, a cylinder liner water outlet, and a concentrated seawater pipe, which is connected to the jet pump. This invention is rationally designed, using a jet pump for water and air extraction. This fully utilizes the kinetic energy of seawater, significantly improving the pump's suction capacity and reducing pressure, thereby lowering the seawater's boiling point and increasing the freshwater yield.

[0004] Regarding the aforementioned technologies, the inventors believe that existing seawater desalination devices use evaporators, which require a significant amount of electrical energy to operate and consume a large amount of power. Summary of the Invention

[0005] In order to collect fresh water while reducing the use of electricity, this application provides a seawater temperature difference energy water generation device.

[0006] This application provides a seawater temperature difference energy water production device, which adopts the following technical solution: A seawater temperature difference energy water generation device includes an insulated box, a pumping insulated pipe connected to the water inlet of the insulated box and extending into the seawater, a conveying insulated pipe connected to the water outlet of the insulated box, a condenser pipe connected to the end of the conveying insulated pipe away from the insulated box, and a return water pipe connected to the end of the condenser pipe away from the conveying insulated pipe. A water pump is installed on the conveying insulated pipe, and a water collection tank for collecting condensate is installed below the condenser pipe.

[0007] By adopting the above technical solution, the water pump allows seawater to pass through the pumping insulation pipe, the insulation box, and the conveying insulation pipe in sequence, and reach the condenser pipe. When the seawater passes through the condenser pipe, the seawater temperature inside the condenser pipe is low, allowing the seawater inside the condenser pipe to exchange heat with the air outside the condenser pipe. This causes water vapor around the condenser pipe to condense on the outside of the condenser pipe, and the water vapor condenses into water droplets that drip into the water collection tank, thus completing the collection of fresh water. This application only requires the power of the water pump, and its energy consumption is low.

[0008] Optionally, the condenser tube is a serpentine condenser tube, which is vertically arranged. The water collection tank is provided with a converging mechanism, which includes a converging motor mounted on the water collection tank, a vertical shaft mounted on the output end of the converging motor, a lower blade mounted on the vertical shaft and located at the lower end of the condenser tube, and an upper blade mounted on the vertical shaft and located at the upper end of the condenser tube. When the lower blade rotates, it blows air into the water collection tank. A gap is provided between adjacent turns of the condenser tube to allow air to pass through.

[0009] By adopting the above technical solution, the converging motor drives the upper and lower blades to rotate through the vertical shaft, so that the lower blades fan air towards the water collection tank and the upper blades fan air towards the inner ring of the condenser tube, which can improve the air circulation around the condenser tube and allow the outside air to come into contact with the outside of the condenser tube more quickly.

[0010] Optionally, the inner ring of the condenser tube is provided with a fixing plate, the top of the fixing plate is provided with a fixing sleeve, the fixing sleeve is sleeved on the outside of the vertical shaft, the outside of the fixing sleeve is rotatably connected to a rotating sleeve, a linkage component for linkage is provided between the vertical shaft and the rotating sleeve, a plurality of spirally arranged wipers are provided on the outside of the rotating sleeve, and a wiper sponge for scraping off the condensate on the inner ring of the condenser tube is provided on the outside of the wipers.

[0011] By adopting the above technical solution, when the vertical shaft rotates, the rotating sleeve is driven to rotate through the linkage component, which in turn drives the wiper component to rotate, so that the wiper sponge can continuously scrape down the water droplets condensed in the inner ring of the condenser tube.

[0012] Optionally, the sweeping area of ​​the lower blade is larger than that of the upper blade.

[0013] By adopting the above technical solution, a negative pressure will appear in the inner ring of the condenser tube, which will allow the air around the condenser tube to enter the inner ring of the condenser tube through the gap between two adjacent rings of the condenser tube.

[0014] Optionally, the water pumping insulation pipe is connected to a cooling pipe, and a valve is provided at the end of the cooling pipe away from the water pumping insulation pipe. The cooling pipe is spirally wound around the outside of the insulation box.

[0015] By adopting the above technical solution, since the cooling pipe is filled with seawater at a temperature lower than that of the outside air, the energy of heat radiation generated by the outside air on the seawater inside the vacuum water tank can be reduced, thereby further improving the heat preservation capacity of the insulated box.

[0016] Optionally, a protective box is provided on the outside of the insulation box. The end of the cooling pipe away from the water-pumping insulation pipe is open. Several pre-cooling pipes are provided inside the protective box near the upper blade. Both ends of the pre-cooling pipes are open. The air inlet of the pre-cooling pipes is connected to the outside. The air outlets of the several pre-cooling pipes are connected to the same pre-cooling cover. The pre-cooling cover is placed on the outside of the upper blade. The water inside the protective box submerges the pre-cooling pipes located inside the protective box.

[0017] By adopting the above technical solution, when the upper blade rotates, a negative pressure will be generated inside the pre-cooling cover, allowing outside air to enter the pre-cooling cover through the pre-cooling pipe. When the outside air passes through the pre-cooling pipe, the air inside the pre-cooling pipe can exchange heat with the seawater at the bottom of the protective box.

[0018] Optionally, the linkage assembly includes a sun gear disposed on the outside of the vertical shaft, a plurality of planetary gears rotatably disposed on the bottom of the fixed sleeve and meshing with the sun gear, and an internal gear ring disposed on the bottom of the rotating sleeve and meshing with the plurality of planetary gears, wherein the internal gear ring is rotatably connected to the fixed plate.

[0019] By adopting the above technical solution, when the vertical shaft drives the sun gear to rotate, the sun gear drives the three planetary gears to rotate in the same direction, the three planetary gears drive the internal gear ring to rotate, and the internal gear ring can thus drive the rotating sleeve to rotate.

[0020] Optionally, the bottom of the rotating sleeve is provided with a flow guide ring plate, which gradually slopes downward away from the vertical axis. The top of the flow guide ring plate is connected to a flow pipe protruding from the surface of the flow guide ring plate, and the flow pipe has several flow holes for air to pass through.

[0021] By adopting the above technical solution, the water droplets scraped off by the squeegee sponge from the inner ring of the condenser tube can flow along the inner wall of the squeegee's thread to the guide ring plate, and then flow along the inclined guide ring plate into the water collection tank, while the air in the inner ring of the condenser tube enters the flow pipe through the flow hole.

[0022] Optionally, both the pumping insulation pipe and the conveying insulation pipe are made of several layers of rubber mesh pipe.

[0023] By adopting the above technical solution, the rubber mesh pipe has a high thermal insulation coefficient, which can reduce the temperature change of seawater in the pumping and conveying insulation pipes.

[0024] Optionally, a filter screen is provided at the end of the water pumping and heat preservation pipe away from the heat preservation box.

[0025] By adopting the above technical solution, the filter screen can filter out impurities in seawater and reduce the phenomenon of blockage in the pumping and insulation pipe.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The water pump causes seawater to pass through the pumping insulation pipe, the insulation box, and the conveying insulation pipe before reaching the condenser pipe. When the seawater passes through the condenser pipe, the seawater temperature inside the condenser pipe is lower, allowing the seawater inside the condenser pipe to exchange heat with the air outside the condenser pipe. This causes water vapor around the condenser pipe to condense on the outside of the condenser pipe, and the water vapor condenses into water droplets that drip into the water collection tank, thus completing the collection of fresh water. 2. The converging motor drives the upper and lower blades to rotate via the vertical shaft, causing the lower blades to fan air towards the water collection tank and the upper blades to fan air towards the inner ring of the condenser tube. This improves the air circulation around the condenser tube and allows outside air to come into contact with the outside of the condenser tube more quickly. 3. Because the air around the condenser tube can enter the inner ring of the condenser tube through the gap between two adjacent rings, during this process, the air can blow the small water droplets that have just condensed on the outside of the condenser tube and slowly blow the small water droplets toward the inner ring of the condenser tube, making it easier for the squeegee to scrape the water droplets off the inner ring of the condenser tube.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a seawater temperature difference energy-based water generation device. (Refer to...) Figure 1 and Figure 2 The seawater thermal energy conversion device includes an insulated tank 1, a pumping insulated pipe 2, a conveying insulated pipe 3, a condenser pipe 4, and a return water pipe 5. A protective box 6 is fixedly installed on the outside of the insulated tank 1, covering the insulated tank 1. The protective box 6 is installed near the coast. The pumping insulated pipe 2 is connected to the top of the insulated tank 1, passes through and extends out of the protective box 6, with the end of the pumping insulated pipe 2 away from the insulated tank 1 extending into the seawater. The conveying insulated pipe 3 is connected to the bottom of the insulated tank 1, with the end of the conveying insulated pipe 3 away from the insulated tank 1 passing through and extending out of the protective box 6. A water pump 7 is installed on the conveying insulated pipe 3.

[0031] The condenser pipe 4 is connected to the end of the conveying insulation pipe 3 away from the insulation box 1. A water collection tank 8 is installed directly below the condenser pipe 4. The return water pipe 5 is connected to the end of the condenser pipe 4 away from the conveying insulation pipe 3. The end of the return water pipe 5 away from the condenser pipe 4 extends into the seawater.

[0032] Before using the device, fill the insulation box 1 with water. After starting the water pump 7, the water pump 7 pumps the water in the insulation box 1 into the delivery insulation pipe 3, creating a negative pressure in the water pumping insulation pipe 2. The negative pressure then draws seawater into the water pumping insulation pipe 2, allowing the seawater to pass through the water pumping insulation pipe 2, the insulation box 1, and the delivery insulation pipe 3 in sequence, reaching the condenser pipe 4. When the seawater passes through the condenser pipe 4, the lower temperature of the seawater inside allows it to exchange heat with the air outside the condenser pipe 4. This causes water vapor around the condenser pipe 4 to condense on the outside of the condenser pipe 4, forming water droplets that drip into the water collection tank 8, thus completing the collection of fresh water. After the heat exchange is complete, the seawater is injected into the sea through the return water pipe 5.

[0033] In this embodiment, both the pumping insulation pipe 2 and the conveying insulation pipe 3 are made of several layers of rubber mesh pipe, specifically seven layers of rubber mesh pipe. The rubber mesh pipe has a high thermal insulation coefficient, which can reduce the temperature change of seawater in the pumping insulation pipe 2 and the conveying insulation pipe 3. In addition, this arrangement can also improve the corrosion resistance of the pumping insulation pipe 2 and the conveying insulation pipe 3.

[0034] It should be noted that the end of the pumping and heat preservation pipe 2, which is away from the heat preservation box 1, extends into the seawater 300 meters below the sea level, and the temperature of the water pumped out is between 10-13℃. The end of the return water pipe 5, which is away from the heat preservation box 1, extends into the seawater 1 meter below the sea level.

[0035] Furthermore, a filter screen is installed at the end of the water pumping and insulation pipe 2 away from the insulation box 1. The filter screen can filter out impurities in the seawater and reduce the phenomenon of blockage in the water pumping and insulation pipe 2.

[0036] Preferably, the insulated box 1 is a vacuum water-absorbing tank, with a vacuum chamber inside the tank body, and the vacuum chamber is set to a vacuum. This setting can prevent heat conduction and heat convection between the seawater inside the vacuum water-absorbing tank and the outside air.

[0037] A cooling pipe 9 is connected to the water pumping insulation pipe 2. The cross-section of the insulation box 1 is circular. The cooling pipe 9 is spirally wound around the outside of the insulation box 1. The end of the cooling pipe 9 away from the water pumping insulation pipe 2 is open. A valve 10 is installed on the cooling pipe 9 away from the water pumping insulation pipe 2. In this embodiment, the valve 10 is a solenoid valve.

[0038] Open valve 10 to allow seawater in the pumping and insulation pipe 2 to flow into the cooling pipe 9. Once the cooling pipe 9 is full of seawater, close valve 10. Because the cooling pipe 9 is filled with seawater at a temperature lower than the outside air, the energy of heat radiation from the outside air to the seawater inside the vacuum pumping tank is reduced, further improving the insulation capacity of the insulation box 1. It should be noted that a drain pipe is fixedly connected to the bottom of the protective box 6, and a solenoid valve is installed on the drain pipe. When the temperature of the seawater at the bottom of the protective box 6 rises, the seawater in the protective box can be discharged through the drain pipe, ensuring that the temperature of the seawater at the bottom of the protective box 6 remains low.

[0039] Reference Figure 3 and Figure 4 Preferably, in this embodiment, the condenser tube 4 is a serpentine condenser tube, which is vertically arranged. A converging mechanism is installed on the top of the water collection tank 8. The converging mechanism includes a converging motor 11, a vertical shaft 12, a lower blade 13, and an upper blade 14. A mounting base is installed on the top of the water collection tank 8. The converging motor 11 is vertically fixed to the top of the mounting base. The vertical shaft 12 is fixed to the output end of the converging motor 11 and extends into the inner ring of the condenser tube 4. The lower blade 13 and the upper blade 14 are both fixedly sleeved on the outside of the vertical shaft 12. The upper blade 14 is located at the upper end of the condenser tube 4, and the lower blade 13 is located at the lower end of the condenser tube 4. It should be noted that when the vertical shaft 12 drives the lower blade 13 to rotate, the lower blade 13 blows air towards the water collection tank 8. When the vertical shaft 12 drives the upper blade 14 to rotate, the upper blade 14 blows air towards the inner ring of the condenser tube 4. In addition, a gap is reserved between adjacent rings of the condenser tube 4 to allow air to pass through.

[0040] The converging motor 11 drives the upper blade 14 and the lower blade 13 to rotate via the vertical shaft 12. The lower blade 13 blows air towards the water collection tank 8, and the upper blade 14 blows air towards the inner ring of the condenser tube 4. This can improve the air circulation around the condenser tube 4, allowing the outside air to come into contact with the outside of the condenser tube 4 more quickly, thereby increasing the speed at which water droplets are condensed from the condenser tube 4.

[0041] Furthermore, it should be noted that the sweeping area of ​​the lower blade 13 is larger than that of the upper blade 14, meaning that the area of ​​a single blade of the lower blade 13 is larger than that of a single blade of the upper blade 14. This design creates a negative pressure within the inner ring of the condenser tube 4, allowing air from around the condenser tube 4 to enter through the gaps between adjacent rings, further increasing the contact between outside air and the condenser tube 4, thereby increasing the velocity of condensation droplets within the condenser tube 4.

[0042] Reference Figure 2 and Figure 3 Preferably, there is a certain distance between the bottom of the protective box 6 and the bottom of the insulation box 1. Several pre-cooling pipes 15 are installed at the bottom of the protective box 6. The pre-cooling pipes 15 are L-shaped and open at both ends. The air inlet of the pre-cooling pipes 15 is connected to the outside. The air outlets of the pre-cooling pipes 15 extend from the bottom of the protective box 6 and are connected to the same pre-cooling cover 16. The pre-cooling pipes 15 are arranged around the circumference of the protective box 6. In addition, the pre-cooling cover 16 is located above the upper blade 14 and covers the outside of the upper blade 14.

[0043] After the seawater in cooling pipe 9 has been used for a period of time, its temperature will rise. At this time, valve 10 is opened to allow the seawater in cooling pipe 9 to flow into the bottom of the protective box 6, allowing new seawater from the insulation pipe 3 to flow into cooling pipe 9, and immersing the pre-cooling pipe 15 located inside the protective box 6 in the seawater in the protective box 6. When the upper blade 14 rotates, it will create a negative pressure inside the pre-cooling cover 16, allowing outside air to enter the pre-cooling cover 16 through the pre-cooling pipe 15. When the outside air passes through the pre-cooling pipe 15, the air inside the pre-cooling pipe 15 can exchange heat with the seawater at the bottom of the protective box 6 to reduce the temperature of the air inside the pre-cooling pipe 15, thereby pre-cooling the air entering the inner ring of the condenser pipe 4 and increasing the speed at which water droplets condense from the condenser pipe 4.

[0044] Reference Figure 3 and Figure 4 Preferably, a fixing plate 17 is fixed to the bottom of the inner ring of the condenser tube 4 by several connecting brackets, and a fixing sleeve 18 is fixed to the top of the fixing plate 17 by several connecting rods. The vertical shaft 12 and the fixing sleeve 18 are rotatably connected by an axial bearing. A rotating sleeve 19 is rotatably sleeved on the outside of the fixing sleeve 18 by an axial bearing. A linkage assembly is installed between the vertical shaft 12 and the rotating sleeve 19, so that the vertical shaft 12 can drive the rotating sleeve 19 to rotate through the linkage assembly. Several wiper parts 20 are fixed on the outside of the rotating sleeve 19. The wiper parts 20 are arranged in a spiral. A wiper sponge 21 is glued to the outside of the wiper parts 20. The wiper sponge 21 contacts the inner ring of the condenser tube 4 with appropriate force.

[0045] When the vertical shaft 12 rotates, it drives the rotating sleeve 19 to rotate through the linkage component, which in turn drives the wiper 20 to rotate, so that the wiper sponge 21 can continuously scrape the water droplets condensed on the inner ring of the condenser tube 4 downwards, shortening the time that the water droplets stay on the inner ring of the condenser tube 4, reducing the time for heat exchange between the water droplets on the condenser tube 4 and the seawater in the condenser tube 4, and increasing the contact time between the outside air and the inner ring of the condenser tube 4.

[0046] Reference Figure 3 and Figure 5 Furthermore, the linkage assembly includes a sun gear 22, planetary gears 23, and an internal gear ring 24. The sun gear 22 is fixedly sleeved on the outside of the vertical shaft 12. The planetary gears 23 are rotatably connected to the bottom of the fixed sleeve 18. There are three planetary gears 23, which are arranged circumferentially on the bottom of the fixed sleeve 18. All three planetary gears 23 mesh with the sun gear 22. The internal gear ring 24 is fixedly connected to the bottom of the rotating sleeve 19, and all three planetary gears 23 mesh with the internal gear ring 24. In addition, a protruding ring 25 is fixed circumferentially on the outer side of the top of the fixed plate 17, and the protruding ring 25 on the top of the fixed plate 17 is rotatably connected to the outer side of the internal gear ring 24 through a bearing.

[0047] When the vertical shaft 12 drives the sun gear 22 to rotate, the sun gear 22 drives the three planetary gears 23 to rotate in the same direction. The three planetary gears 23 drive the internal gear ring 24 to rotate, and the internal gear ring 24 can thus drive the rotating sleeve 19 to rotate, so that the rotational speed of the rotating sleeve 19 is less than the rotational speed of the vertical shaft 12.

[0048] Reference Figure 3 and Figure 4 A guide ring plate 26 is fixed at the bottom of the rotating sleeve 19. The guide ring plate 26 gradually slopes downward away from the vertical axis 12. Several flow pipes 27 are connected to the top of the guide ring plate 26. The flow pipes 27 are arranged circumferentially along the guide ring plate 26 and protrude from the surface of the guide ring plate 26. The flow pipes 27 are provided with several flow holes for air to pass through. With this configuration, the water droplets scraped off by the wiper sponge 21 from the inner ring of the condenser tube 4 can flow along the inner wall of the wiper 20 thread to the guide ring plate 26, and then flow along the inclined guide ring plate 26 into the water collection tank 8. Meanwhile, the air in the inner ring of the condenser tube 4 enters the flow pipe 27 through the flow holes and is blown towards the water collection tank 8 as the lower blade 13 rotates, making it difficult for water droplets to pass through the middle of the guide ring plate 26, thus protecting the lower blade 13 and the converging motor 11.

[0049] It should be noted that, since the air around the condenser tube 4 can enter the inner ring of the condenser tube 4 through the gap between two adjacent rings of the condenser tube 4, during this process, the air can blow the small water droplets that have just condensed on the outside of the condenser tube 4 and slowly blow the small water droplets toward the inner ring of the condenser tube 4, so that the scraper 20 can scrape off the water droplets on the inner ring of the condenser tube 4.

[0050] Preferably, a water guide ring plate 28 is circumferentially fixed at the bottom of the condenser tube 4, covering the lower blade 13 inside. The water guide ring plate 28 is inclined downward along the direction close to the lower blade 13, and a space is reserved between the lower end of the water guide ring plate 28 and the outer side of the lower blade 13 for water droplets to flow down. This arrangement allows the air in the inner ring of the condenser tube 4 to be smoothly drawn to the outside through the lower blade 13, and the water droplets flow through the guide ring plate 26 to the water guide ring plate 28, and then smoothly flow along the inclined inner wall into the water collection tank 8, realizing the collection of fresh water.

[0051] The implementation principle of the seawater temperature difference energy water generation device in this application embodiment is as follows: The end of the pumping and insulation pipe 2 furthest from the insulation box 1 is extended into seawater 300 meters below sea level. Before using the device, the insulation box 1 is filled with water. After starting the pumping pump 7, the pumping pump 7 draws the water from the insulation box 1 into the conveying and insulation pipe 3, creating a negative pressure inside the pumping and insulation pipe 2. This negative pressure draws seawater into the pumping and insulation pipe 2, allowing the seawater to pass through the pumping and insulation pipe 2, the insulation box 1, and the conveying and insulation pipe 3 sequentially, reaching the condenser pipe 4. When the seawater passes through the condenser pipe 4, due to the lower temperature of the seawater inside the condenser pipe 4, the seawater inside the condenser pipe 4 can exchange heat with the air outside the condenser pipe 4, causing water vapor around the condenser pipe 4 to condense on its outside. On the side, water vapor condenses into water droplets and drips into the water collection tank 8; the converging motor 11 drives the upper blade 14 and the lower blade 13 to rotate through the vertical shaft 12, so that the lower blade 13 blows air towards the water collection tank 8 and the upper blade 14 blows air towards the inner ring of the condenser tube 4, so that the air around the condenser tube 4 can enter the inner ring of the condenser tube 4 through the gap between the two adjacent rings of the condenser tube 4. When the vertical shaft 12 rotates, it drives the rotating sleeve 19 to rotate through the linkage component, so that the scraper 20 rotates, so that the scraper sponge 21 can continuously scrape down the water droplets condensed in the inner ring of the condenser tube 4. The water droplets flow through the guide ring plate 26 to the water guide ring plate 28, and flow smoothly along the inclined inner wall into the water collection tank 8, realizing the collection of fresh water. This application only needs to provide the power of the water pump 7, which has low energy consumption.

[0052] This completes the collection of fresh water, while the seawater, after heat exchange, is injected into the ocean through a return pipe.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
