Description
Technical Field
[0001] This invention relates to the field of air moisture capture, and in particular to a solar-powered continuous air moisture capture device. Background Technology
[0002] Water resources are the material basis for all production and life in human society.
[0003] Water is the most abundant resource in the natural environment, and the total water storage on Earth is approximately 1.386 × 10¹⁸ m³. 3 However, freshwater resources available for direct human use are very limited, accounting for only 0.36% of total water resources. This portion of water resources mainly exists underground, on the surface, and in the air. The atmosphere is rich in freshwater and is not limited by geographical location, especially in areas near lakes and coastal regions where air humidity is high. It is estimated that the entire atmosphere contains approximately 1.4 × 10⁻⁶ freshwater. 7 m 3 The water vapor in it is about 12 times the total amount of surface freshwater.
[0004] Air-based water extraction technology is one of the effective methods to solve the problem of freshwater scarcity, and can meet human needs for freshwater resources under certain specific conditions. Currently, air-based water extraction technology is a hot research topic for many scholars both domestically and internationally. Solar-driven interfacial water evaporation technology has also gradually attracted widespread attention in the academic community. Adsorption-based air-based water extraction technology is divided into traditional adsorption-based air-based water extraction technology and continuous air-based water extraction technology. Traditional adsorption-based air-based water extraction is an intermittent system that adsorbs at night and desorbs during the day, while continuous air-based water extraction is a continuous system that adsorbs at night and adsorbs and desorbs during the day. However, neither traditional adsorption-based nor continuous air-based water extraction technology can desorb at night; under harsh climatic conditions, existing air-based water extraction devices are difficult to complete the water extraction task. Summary of the Invention
[0005] This invention provides a solar-powered continuous air moisture capture device that uses a combination of light and electric heating to complete the desorption process during the day and night, solving the problem of continuously collecting moisture from the air for use.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a solar-powered continuous air moisture capture device, including a water storage tank connected to the outside, a sealed chamber above the water storage tank, a water collection tank inside the sealed chamber, and a cylindrical three-dimensional water-absorbing core. The lower end of the cylindrical three-dimensional water-absorbing core is located in the water storage tank near the bottom, and a cylindrical interface evaporator is located at the upper end of the cylindrical three-dimensional water-absorbing core. The cylindrical interface evaporator is located in the sealed chamber. A desiccant is provided in the water storage tank and the cylindrical three-dimensional water-absorbing core. A condenser plate is provided in the water collection tank near the top of the cylindrical interface evaporator. A solar photovoltaic power generation panel and a battery are also provided. An electric heating device is provided in the cylindrical interface evaporator, and the solar photovoltaic power generation panel and the battery are electrically connected to the electric heating device.
[0007] In the preferred embodiment, the upper end of the cylindrical interface evaporator is provided with a photothermal material, which is a porous, dark-colored heat-absorbing material.
[0008] In the preferred embodiment, a temperature sensor and a sunlight sensor are provided at the photothermal material.
[0009] In the preferred embodiment, the outer side of the cylindrical three-dimensional water-absorbing core is provided with multiple water-collecting cores along the circumferential direction. The water-collecting cores are inserted into the water storage tank. The water-collecting cores include multiple concentric and spaced water-collecting cylindrical surfaces. Each water-collecting cylindrical surface is provided with a breathable groove. The sidewalls and lower ends of the water-collecting cylindrical surfaces are porous. The water-collecting cylindrical surfaces are provided with a hollow inner cavity. The hollow inner cavity of the water-collecting cylindrical surfaces is provided with a desiccant.
[0010] In the preferred embodiment, the water collecting core is inserted into the water storage tank from the upper end face of the water storage tank. The water collecting core includes a core seat, which is detachably connected to the upper end face of the water storage tank. Thin film rings are provided on the inner and outer sides of the lower end of each water collecting column, and a bundle-gathering device is provided at the lower end of the thin film rings.
[0011] In a preferred embodiment, the bundling device includes a porous seat with a hollow tube at its center. Multiple hollow tubes are arranged circumferentially on the outer side of the central hollow tube, and the hollow tubes penetrate the porous seat. Multiple deformable pieces are arranged circumferentially on the outer side of the porous seat, and a locking ring is provided on the outer side of the deformable pieces. The locking ring is threadedly connected to the deformable pieces. The deformable pieces have an outer wedge-shaped surface, and the locking ring has an inner wedge-shaped surface. The locking ring rotates to compress and tighten the deformable pieces.
[0012] In the preferred embodiment, the side wall of the water storage tank is provided with an inward bend near the top, and a baffle is provided at the top of the inside of the water storage tank near the side wall, with a gap between the baffle and the side wall of the water storage tank.
[0013] In the preferred embodiment, the side wall of the sealed chamber is provided with a light-transmitting window, and multiple reflectors are provided on the outer side of the sealed chamber along the circumference. Light is reflected by the reflectors and shines onto the photothermal material through the light-transmitting window.

[0015] In the preferred embodiment, water storage tanks are provided on both sides of the water storage tank, and water supply pipes are also provided. The water collection tank is connected to the water storage tank through the water supply pipes.
[0016] The beneficial effects of this invention are as follows: It collects moisture from the air using a desiccant, and the cylindrical interface evaporator is heated by sunlight to evaporate the moisture, thus purifying the water while collecting airborne moisture, resulting in cleanliness and energy saving. The device is low-cost, stable, reliable, and sustainable, requiring minimal manual operation. It employs a conveniently installed and disassembled water collection core, filled with desiccant for continuous moisture collection. The large contact area with the air ensures a wide collection range. The water collection core hangs above the water tank, absorbing moisture and relying on gravity to form water droplets. The desiccant at the top remains unsaturated, allowing for continuous use without replacement, thus improving the utilization rate of the desiccant. Simultaneously, the lower end of the water collection core avoids contact with the water surface to prevent reduced collection efficiency. The lower end of the water collection core uses a thin-film bundle design, which accelerates the formation of water droplets, ensuring a stable flow rate. Attached Figure Description

Detailed Implementation
[0030] Example 1:
[0031] like Figure 1-11 A solar-powered continuous air moisture capture device includes a water storage tank 15, which is connected to the outside. A sealed chamber 24 is provided above the water storage tank 15, and a water collection tank 19 is provided inside the sealed chamber 24. A cylindrical three-dimensional water absorption core 21 is also provided. The lower end of the cylindrical three-dimensional water absorption core 21 is located inside the water storage tank 15 near the bottom. A cylindrical interface evaporator 17 is provided at the upper end of the cylindrical three-dimensional water absorption core 21. The cylindrical interface evaporator 17 is located inside the sealed chamber 24. A desiccant is provided in the water storage tank 15 and the cylindrical three-dimensional water absorption core 21. A condenser plate 23 is provided inside the water collection tank 19 near the top of the cylindrical interface evaporator 17.
[0032] The water tank 15 can be filled with desiccant to enhance its ability to capture moisture.
[0033] It is also equipped with a solar photovoltaic panel 1 and a storage battery 6. The cylindrical interface evaporator 17 is equipped with an electric heating device, and the solar photovoltaic panel 1 and the storage battery 6 are electrically connected to the electric heating device.
[0034] In a preferred embodiment, the upper end of the cylindrical interface evaporator 17 is provided with a photothermal material 16, which is a porous, dark-colored heat-absorbing material.
[0035] The electric heating device is located on the lower side of the photothermal material 16.
[0036] On sunny days, the solar photovoltaic panel 1 absorbs solar energy and stores it in the battery 6. Sunlight shines on the photothermal material 16. Because the photothermal material 16 is dark in color and has a strong heat absorption capacity, its temperature rises rapidly. The water in the cylindrical three-dimensional water-absorbing core 21 rises to the photothermal material 16 through capillary action, seeps out from the pores, and is heated and evaporated. When it encounters the cooler condensing plate 23, it condenses into water droplets and flows from the lower sides, finally falling into the water collection tank 19. A water baffle is set on the outside of the cylindrical interface evaporator 17 to separate it. On cloudy days or at night, the electric heating device on the lower side of the photothermal material 16 is turned on to actively heat it, increase the evaporation rate, and ensure continuous water collection day and night.
[0037] The plate at the junction of the upper end face of the water storage tank 15 and the lower end face of the sealing chamber 24 is made of heat insulation material. The contact surface between the lower end face of the columnar interface evaporator 17 and the lower end face of the sealing chamber 24 is provided with a water-permeable heat insulation layer 18. The water-permeable heat insulation layer 18 is porous and made of heat insulation material.
[0038] The condenser plate 23 is equipped with a cooling device 22, i.e. a cooling chip. The cooling device 22 is electrically connected to the solar photovoltaic panel 1 and can generate electricity through solar power to cool down the condenser plate 23.
[0039] In the preferred embodiment, a temperature sensor 25 and a sunlight sensor 26 are provided at the photothermal material 16.
[0040] The solar sensor 26 detects the intensity of sunlight, and the temperature sensor 25 monitors whether the temperature of the photothermal material 16 has reached the set standard. If either the light intensity or the temperature does not reach the set value, the electric heating device can be turned on to heat the material.
[0041] While filling the water tank 15 with desiccant can increase the amount of water absorbed, the desiccant in the inner layer has difficulty coming into contact with the air, resulting in low utilization. Furthermore, since the desiccant is soaked in water and remains saturated, it cannot continue to come into contact with the air, which inadvertently limits its ability to absorb moisture.
[0042] Therefore, in the preferred embodiment, the outer side of the cylindrical three-dimensional water-absorbing core 21 is provided with a plurality of water-collecting cores 28 along the circumferential direction. The water-collecting cores 28 are inserted into the water storage tank 15. The water-collecting cores 28 include a plurality of concentric and spaced water-collecting cylindrical surfaces 2801. Each water-collecting cylindrical surface 2801 is provided with a breathable groove 2802. The sidewalls and lower ends of the water-collecting cylindrical surface 2801 are porous. The water-collecting cylindrical surface 2801 is provided with a hollow inner cavity. The hollow inner cavity of the water-collecting cylindrical surface 2801 is provided with a desiccant.
[0043] Because multiple water collecting columns 2801 are arranged concentrically, the total contact area between the water collecting core 28 and the air is large. The side walls of the water collecting columns 2801 are breathable. When the desiccant reaches saturation, due to gravity, the water at the bottom of the water collecting core 28 begins to condense into water droplets and drips continuously into the water storage tank 15.
[0044] The bottom of the water storage tank 15 adopts a sloping structure 1501, with a low columnar three-dimensional water absorption core 21 in the middle and a high water collection core 28 on the outside, to prevent the lower end of the water collection core 28 from being submerged, thus reducing the ability to collect and drip water.
[0045] In the preferred embodiment, the water collecting core 28 is inserted into the water storage tank 15 from the upper end face of the water storage tank 15. The water collecting core 28 includes a core seat 2805, which is detachably connected to the upper end face of the water storage tank 15. Each water collecting column surface 2801 has a thin film ring 2804 on its inner and outer sides at the lower end, and a bundled device 2803 is provided at the lower end of the thin film ring 2804.
[0046] The upper end of the thin film ring 2804 is tightly attached to and connected to the side wall of the water collecting column 2801. The lower end of the thin film ring 2804 is constrained into a thin bundle by the bundling device 2803. Taking three water collecting columns 2801 as an example, six thin film rings 2804 are used to divide the lower end of the water collecting core 28 into eleven gradually narrowing collecting ring cavities. After the desiccant in the water collecting column 2801 is saturated, it gathers downward under the action of gravity, dripping from the bottom of the water collecting column 2801 or flowing down along the thin film ring 2804 to the narrowing point. Due to the intermolecular forces, it is easier to gather into large water droplets at the narrowing point. Since the thin film ring 2804 is generally made of plastic, many irregular wrinkles will be generated when it is bundled. As long as the bundling device 2803 is not tied too tightly, the wrinkles will naturally create pores, allowing water droplets to drain out and drip into the water storage tank 15.
[0047] In a preferred embodiment, the clustering device 2803 includes a porous seat 2806, with a hollow tube 2807 at its center. Multiple hollow tubes 2807 are arranged circumferentially around the central hollow tube 2807. The hollow tubes 2807 penetrate the porous seat 2806. Multiple deformable pieces 2808 are arranged circumferentially around the outer side of the porous seat 2806. A locking ring 2809 is provided on the outer side of each deformable piece 2808. The locking ring 2809 is threadedly connected to the deformable piece 2808. The deformable piece 2808 has an outer wedge-shaped surface, and the locking ring 2809 has an inner wedge-shaped surface. The locking ring 2809 rotates to compress and tighten the deformable piece 2808.
[0048] During installation, each diaphragm ring 2804 is inserted between the hollow tubes 2807. The deformation plate 2808 can elastically deform. When the inner wedge-shaped surface of the locking ring 2809 presses against the outer wedge-shaped surface of the deformation plate 2808, the deformation plate 2808 clamps the outermost diaphragm ring 2804. Compared to wrinkles, due to the presence of the hollow tubes 2807, a stable gap is generated between the diaphragm rings 2804, making the water passage smoother. Water can drip steadily from the hollow tubes 2807, ensuring the water flow rate.
[0049] In a preferred embodiment, the side wall of the water storage tank 15 is provided with an inner bend 1502 near the top, and the top of the inside of the water storage tank 15 is provided with a retaining edge 1504 near the side wall, with a gap between the retaining edge 1504 and the side wall of the water storage tank 15.
[0050] The concave inner bend 1502 creates a ventilation hole 1503, allowing the water tank 15 to connect with the outside, improving ventilation and preventing dust and debris from easily falling into the water tank 15. Water vapor that naturally evaporates inside the water tank 15 gathers and falls through the baffle 1504, which is spaced a certain distance from the inner bend 1502 to prevent water droplets from dripping out of the water tank 15.
[0051] In a preferred embodiment, the side wall of the sealed chamber 24 is provided with a light-transmitting window 2401, and a plurality of reflectors 27 are provided on the outer side of the sealed chamber 24 along the circumference. Light is reflected by the reflectors 27 and irradiated onto the photothermal material 16 through the light-transmitting window 2401.
[0052] Light should be directed away from the condenser plate 23 to prevent sunlight from heating it up. The angle of the reflector 27 can be adjusted according to the direction of the sun.
[0053] In the preferred embodiment, a water collection tank 12 is provided at the upper end of the sealed chamber 24, the upper end of the water collection tank 12 is open, water storage tanks 13 are provided on both sides of the water storage tank 15, and a water supply pipe 10 is also provided. The water collection tank 12 and the water storage tank 13 are connected through the water supply pipe 10, and a filter device is provided at the connection between the water collection tank 12 and the water supply pipe 10.
[0054] The water collection tank 12 collects rainwater from rainy days, allowing sedimentation to reduce impurities. A filter screen is installed at the connection between the water collection tank 12 and the water supply pipe 10 to transfer clean rainwater to the storage tank 13 for storage. Since the rainwater accumulates on the upper layer, closer to the condenser plate 23, it can also reduce the temperature of the condenser plate 23 to some extent.
[0055] In the preferred embodiment, water storage tanks 13 are provided on both sides of the water storage tank 15, and water supply pipes 10 are also provided. The water collection tank 19 is connected to the water storage tanks 13 through the water supply pipes 10.
[0056] The clean water that has been filtered through evaporation in the water collection tank 19 is transferred to the water storage tank 13 for storage.
[0057] Example 2:
[0058] A solar-powered interfacial evaporation sustainable water intake device, comprising a solar photovoltaic power generation system and an interfacial evaporation sustainable water intake system.
[0059] The solar photovoltaic power generation system mainly consists of a solar photovoltaic panel 1, a distribution box 5, a battery 6, a pulse width modulation photovoltaic controller 3, an inverter 9, and an FCS control system 7. The solar photovoltaic panel 1 is detachably connected to the support frame. The distribution box 5 is mechanically installed at 1 / 3 of the distance from the top of the support frame. A drainage component 2 is installed on the upper part of the distribution box 5. The transmission line 8 connects the solar photovoltaic panel 1 to the battery 6, the pulse width modulation photovoltaic controller 3, the inverter 9, and the FCS control system 7 installed in the distribution box 5.
[0060] The interface evaporation sustainable water intake system consists of a water collection tank 12, a sealed chamber 24, a water collection box 19, a condenser plate 23, a baffle plate 20, a water supply pipe 10, a photothermal material 16, a columnar interface evaporator 17, a columnar three-dimensional water-absorbing core 21, a water-permeable heat insulation layer 18, and a water storage tank 13. The upper surface of the condenser plate 23 is connected to the bottom of the water collection tank 12. The water collection tank 12 has water outlets at both ends, which are fixedly connected to the water storage tank 13 through the water supply pipe 10. The condenser plate 23 is arranged in a herringbone shape. The upper surface of the columnar interface evaporator 17 is connected to the lower surface of the photothermal material 16, and the lower surface is connected to the water-permeable heat insulation layer 18. The water-permeable heat insulation layer 18 is located about 1 / 3 away from the upper surface of the columnar three-dimensional water absorption core 21. The baffle plate 20 is fixedly connected to the bottom plate of the sealing chamber 24. The water collection tank 19 has water outlets at both ends, which are connected to the water outlet pipe 14. The water storage tank 15 is fixedly connected to the water storage tank 13. The water outlets at both ends of the water storage tank 13 are fixedly connected to the water outlet pipe 14.
[0061] The solar photovoltaic panel 1 can absorb solar energy and convert it into electrical energy, which is then stored in the battery 6 by the pulse width modulation photovoltaic controller 3. The pulse width modulation photovoltaic controller 3 tracks and transforms the electricity generated by the solar photovoltaic panel 1 and stores it in the battery 6. Its function is to protect the battery 6 and prevent it from being overcharged and over-discharged.
[0062] The inverter 9 is a converter that transforms the DC power released by the battery 6 into AC power (generally 220V, 50Hz sine wave) with fixed frequency and voltage or frequency and voltage regulation, to supply the normal operation of the FCS system control system 7, the condenser plate 23 and the cylindrical interface evaporator 17.
[0063] The FCS control system 7 mainly controls the normal operation of the heating wire in the cylindrical interface evaporator 17. The FCS control system 7 includes a solar sensor 26, a temperature sensor 25, three control switches, and the heating wire in the cylindrical interface evaporator 17; the solar sensor 26 is set on the upper surface of the photothermal material 16, and it can accurately identify day and night, various weather conditions, and the position of the sun.
[0064] The photothermal material 16 is a carbon-based porous material, which can achieve high photothermal conversion efficiency.
[0065] The permeable heat insulation layer 18 is permeable to water and isolates the heat generated by the heating wire in the cylindrical interface evaporator, preventing the generated heat from being transferred to the bottom of the cylindrical three-dimensional water-absorbing core 21.
[0066] The working process of the solar-powered interface evaporation sustainable water extraction device is as follows:
[0067] Adsorption process:
[0068] The solid or liquid adsorbent in the water storage tank 15 adsorbs water molecules in the air, and the water molecules are transferred to the top of the columnar three-dimensional water absorption core 21 through the columnar three-dimensional water absorption core 21.
[0069] Desorption process:
[0070] The solar photovoltaic panel 1 absorbs solar energy and converts it into electrical energy, which is then stored in the battery 6 via the pulse width modulation photovoltaic controller 3. The inverter 9 converts the DC power released from the battery 6 into AC power to supply the normal operation of the FCS control system 7, the cold electricity generation device 22 in the condenser plate 23, and the heating wire.
[0071] During the day, when the solar sensor 26 in the FCS control system 7 detects sunlight, the first control switch is turned on, and the temperature sensor 25 is activated to measure the temperature of the lower surface of the photothermal material 16. When the temperature of the lower surface of the photothermal material 16 is lower than the temperature value set by the temperature sensor 25, the sunlight intensity is weak, and the photothermal material 16 cannot operate normally. The second control switch is then turned on, and the heating wire in the cylindrical interface evaporator 17 is activated. When the temperature of the lower surface of the photothermal material 16 is higher than the temperature value set by the temperature sensor 25, the sunlight intensity is strong, and the photothermal material 16 can operate normally. The first control switch is then turned off, and the heating wire is deactivated.
[0072] At night, when the solar sensor 26 in the FCS control system 7 does not detect sunlight, the photothermal material 16 cannot operate normally. The first control switch and the second control switch are closed, the third control switch is turned on, and the heating wire in the cylindrical interface evaporator 17 is in working condition.
[0073] When the heating wire or photothermal material 16 in the interface evaporation device is in working condition, the water molecules in the cylindrical three-dimensional water-absorbing core 21 will evaporate and rise. The water vapor will condense into water droplets when it encounters the condensing plate 23. The condensed water droplets will flow along the condensing plate 23 to both sides and flow into the water collection tanks 19 on both sides. The water in the water collection tank 19 will be guided to the water storage tank 13 through the water supply pipe 10, and finally flow out of the water storage tank 13 from the water outlet pipes 14 at both ends of the water storage tank 13.
[0074] When it rains, the water collection tank 12 in the device can collect the rainwater, which flows into the water storage tank 13 through the water supply pipes 10 at both ends of the water collection tank 12, and flows out of the water storage tank 13 through the water outlet pipes 14 at both ends of the water storage tank 13. In addition, the device can continue to operate in adverse weather conditions such as cloudy days, heavy rain, strong winds, and dense fog.
