Abstract

This invention provides a waste heat-driven adsorption-condensation coupled air-to-water system, comprising a photovoltaic panel, a microchannel phase change heat pipe array, a multi-module adsorption mechanism, a radiant cooling plate, and a water storage tank. The multi-module adsorption mechanism includes a support rod, an electric turntable, a rotating column, a first adsorption layer, a second adsorption layer, a metal pendant plate, an L-shaped magnetic plate, a horizontal rod, a vertical rod, a first electric actuator, and a main control unit. The waste heat generated by the photovoltaic panel can be transferred by the microchannel phase change heat pipe array to the first or second adsorption layer for desorption.

Description

Technical Field

[0001] This invention relates to the field of air water extraction technology, and in particular to a waste heat-driven adsorption-condensation coupled air water extraction system. Background Technology

[0002] With the continuous growth of the population, the global water shortage problem is becoming increasingly severe. Air-based water extraction technology has become a research hotspot due to its environmental adaptability. Current air-based water extraction methods include condensation, membrane separation, and adsorption. Condensation uses refrigeration equipment such as semiconductor cooling chips and compressors to cool the air below the dew point to achieve water vapor condensation. However, in low-humidity environments, the lower dew point leads to a sharp increase in energy consumption and a significant decrease in efficiency, making it difficult to meet the needs of arid regions. Membrane separation utilizes the preferential adsorption characteristics of selectively permeable membranes to achieve separation. Although there is no phase change energy consumption, the membrane materials are expensive and susceptible to dust contamination. The current adsorption method, which uses adsorbents (such as silica gel, zeolite, and metal-organic frameworks, MOFs) to adsorb moisture from the air at low temperatures, and then releases high-concentration water vapor through heating and desorption, which is then condensed into water, is more efficient and cheaper than condensation and membrane separation. However, most current adsorption methods use a single adsorbent material for adsorption and desorption, which cannot adapt to different environments. Furthermore, desorption often requires an additional heat source, failing to effectively combine with the waste heat generated during photovoltaic power generation to achieve efficient resource utilization.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] ① The waste heat generated during photovoltaic power generation can be transferred through a microchannel phase change heat pipe array. The waste heat can desorb the first or second adsorption layer, releasing water vapor into the air. A radiant cooling plate is set at the bottom of the first and second adsorption layers. The surface temperature is reduced through radiation. When the water vapor comes into contact with the bottom surface of the radiant cooling plate, it will condense into liquid water and flow into the water storage tank for collection along the biomimetic spider silk guide channel. This realizes the rational utilization of photovoltaic waste heat and improves resource utilization.

[0017] ② The desorption temperatures of the first and second adsorption layers are different. The electric turntable can rotate the different adsorption layers to the bottom of the photovoltaic panel through the rotating column to adapt to different temperature environments. When the adsorption layer is moved to the bottom, the first electric push rod can drive the L-shaped magnetic plate to move horizontally through the vertical and horizontal rods and move it to the bottom of the rotating column. The L-shaped magnetic plate and the metal pendant plate can seal the lower adsorption layer to prevent water vapor in the air from being adsorbed by the lower adsorption layer and affecting the normal water intake process.

[0025] To better understand the technical content of this invention, a specific embodiment is provided below, and the invention will be further described in conjunction with the accompanying drawings.

[0026] See Figures 1 to 5This invention provides a waste heat-driven adsorption-condensation coupled air-water collection system, comprising a photovoltaic panel 1, a microchannel phase change heat pipe array 2, a multi-module adsorption mechanism, a radiant cooling plate 3, and a water storage tank 4. The microchannel phase change heat pipe array 2 is disposed on the bottom surface of the photovoltaic panel 1. The multi-module adsorption mechanism is located below the microchannel phase change heat pipe array 2. The radiant cooling plate 3 is disposed below the multi-module adsorption mechanism, and its top surface is coated with a hydrophobic coating and a cooling coating. The bottom surface of the radiant cooling plate 3 is provided with a biomimetic spider silk guide groove 5. The water storage tank 4 is located below the radiant cooling plate 3. The multi-module adsorption mechanism includes support rods 6, an electric turntable 7, a rotating column 8, a first adsorption layer 9, a second adsorption layer 10, a metal pendant plate 11, an L-shaped magnetic plate 12, a horizontal rod 13, a vertical rod 14, a first electric actuator 15, and a main control unit 16. The support rods 6 are arranged opposite each other. The electric turntable 7 is symmetrically arranged on the side walls of the support rod 6. The rotating column 8 is located between the electric turntables 7, and its two ends are connected to the rotating surface of the electric turntable 7. The first adsorption layer 9 and the second adsorption layer 10 are respectively arranged on the top and bottom surfaces of the rotating column 8, and the desorption temperatures of the first adsorption layer 9 and the second adsorption layer 10 are different. The metal pendant plate 11 is rotatably arranged on the side wall of the rotating column 8. The side wall of the support rod 6 is provided with a through-hole 17. The L-shaped magnetic plate 12 passes through the through-hole 17. The horizontal rod 13 connects the L-shaped magnetic plate 12 and the side wall of the vertical rod 14. The first electric push rod 15 is arranged on the side wall of the support rod 6, and its output shaft is connected to the outer wall of the vertical rod 14. The metal pendant plate 11 is located above the moving path of the L-shaped magnetic plate 12. The main control unit 16 is arranged on the outer wall of the support rod 6 and is electrically connected to the electric turntable 7 and the first electric push rod 15 respectively.

[0027] Photovoltaic panel 1 is used to convert solar energy into electrical energy to power electrical equipment. During the photovoltaic conversion process, photovoltaic panel 1 generates a large amount of waste heat. A microchannel phase change heat pipe array 2 is installed on the back of photovoltaic panel 1. The microchannel phase change heat pipe array 2 uses a nanofluid working fluid, such as graphene-acetone composite material, which can not only transfer waste heat but also reduce the temperature of photovoltaic panel 1, improving its power generation efficiency. Below the microchannel phase change heat pipe array 2 is a first adsorption layer 9 or a second adsorption layer 10. The waste heat transferred by the microchannel phase change heat pipe array 2 can desorb water vapor from the first adsorption layer 9 or the second adsorption layer 10, releasing water vapor into the air environment. Below the second adsorption layer 10 is the radiative cooling plate 3. Combined with radiative cooling technology, efficient condensation can be achieved without an additional cold source. When water vapor comes into contact with the bottom surface of the radiative cooling plate 3, it can be cooled into liquid water. The bottom surface of the radiative cooling plate 3 is a biomimetic spider silk guide channel 5, which can guide water droplets to flow along a preset path through the surface tension gradient, improving the collection efficiency by 30%. The hydrophobic coating and cooling coating on its top surface can reflect sunlight and dissipate heat through infrared radiation, reducing the temperature and improving the condensation efficiency. Finally, the condensed water will drip into the water storage tank 4 for collection, realizing air water collection. This not only makes reasonable use of photovoltaic waste heat, but also does not require an additional cold source in the cooling process, improving the efficiency of air water collection.

[0028] The first adsorption layer 9 and the second adsorption layer 10 use different adsorption materials and have different desorption temperatures. The first adsorption layer 9 and the second adsorption layer 10 are respectively placed on the upper and lower surfaces of the rotating column 8. The rotating column 8 can be rotated by the electric turntable 7 on the support rod 6, thereby rotating either the first adsorption layer 9 or the second adsorption layer 10 below the microchannel phase change heat pipe array 2. This allows for desorption based on different temperatures, adapting to different environments. To prevent the lower adsorption layer from adsorbing water vapor during desorption of the upper adsorption layer, a metal drooping plate 11 is provided on the side wall of the rotating column 8. When the adsorption layer 9 or the second adsorption layer 10 is on top, the metal pendant plate 11 always remains in a pendant state. The main control unit 16 can drive the first electric push rod 15 to move the vertical rod 14. The vertical rod 14 drives the L-shaped magnetic plate 12 to move along the passage 17 through the horizontal rod 13. During the movement, the L-shaped magnetic plate 12 can contact the bottom surface of the metal pendant plate 11 and move along the bottom surface of the metal pendant plate 11. Finally, the L-shaped magnetic plate 12 and the metal pendant plate 11 are magnetically attracted, and the lower adsorption layer is covered inside. This can prevent water vapor from being adsorbed by the lower adsorption layer, thereby ensuring the normal operation of air water intake.

[0029] Preferably, the first adsorption layer 9 is filled with lithium chloride modified hydrogel, and the second adsorption layer 10 is filled with MOF material.

[0030] The desorption temperature of lithium chloride modified hydrogel is 50-60℃, while that of MOF is 40-50℃. During daylight, the first adsorption layer 9 is on top, and the desorption of lithium chloride modified hydrogel can be achieved through waste heat. When the light is insufficient, the second adsorption layer 10 is on top, and the desorption of MOF can be achieved through residual heat.

[0031] Preferably, the multi-module adsorption mechanism includes a sleeve 18, a rotating shaft 19, and a connecting rod 20. The sleeve 18 is disposed on the side wall of the rotating column 8 and has an arc-shaped groove 21. The rotating shaft 19 is located inside the sleeve 18. The top end of the connecting rod 20 extends into the sleeve 18 through the arc-shaped groove 21 and connects to the outer wall of the rotating shaft 19. Its bottom end is connected to the top surface of the metal pendant plate 11.

[0032] When the rotating column 8 rotates, it will cause the first adsorption layer 9 or the second adsorption layer 10 to face upwards. During the rotation, the metal drooping plate 11 will be driven by gravity to rotate the rotating shaft 19 inside the sleeve 18 through the connecting rod 20. The connecting rod 20 will rotate along the arc groove 21, so that the metal drooping plate 11 always maintains a drooping posture.

[0033] Preferably, the upper surface of the L-shaped magnetic plate 12 is provided with a groove 22, and the bottom surface of the metal pendant plate 11 is located on the moving path of the groove 22.

[0034] To ensure accurate alignment between the L-shaped magnetic plate 12 and the metal pendant plate 11, a groove 22 is provided on the upper surface of the L-shaped magnetic plate 12. When the L-shaped magnetic plate 12 moves, the bottom surface of the metal pendant plate 11 will be engaged in the groove 22, ensuring the stability of the movement of the L-shaped magnetic plate 12.

[0035] Preferably, it also includes a mounting rod 23, one end of which is connected to the side wall of the metal drooping plate 11, and the other end is connected to the support rod 6.

[0036] The mounting rod 23 can be used to fix the radiant cooling plate 3, ensuring that the radiant cooling plate 3 can be stably positioned below the rotating column 8.

[0037] Preferably, a self-testing mechanism is also included. The first adsorption layer 9 and the second adsorption layer 10 are composed of several adsorption modules 24. The self-testing mechanism includes a pressure sensor 25, a force spring 26, a water pump 27, a corrugated pipe 28, a water supply pipe 29, and an atomizing nozzle 30. The pressure sensor 25 is disposed on the top and bottom surfaces of the rotating column 8. The force spring 26 connects the pressure sensor 25 and the adsorption modules 24. The water pump 27 is disposed on the horizontal rod 13. The corrugated pipe 28 connects the water inlet of the water pump 27 and the side wall of the water storage tank 4. One end of the water supply pipe 29 is connected to the water outlet of the water pump 27, and the other end passes through the interior of the L-shaped magnetic plate 12. The atomizing nozzle 30 is embedded in the upper surface of the L-shaped magnetic plate 12 and connected to the water supply pipe 29. The rotating column 8 is located above the moving path of the atomizing nozzle 30. The main control unit 16 is electrically connected to the pressure sensor 25, the water pump 27, and the atomizing nozzle 30.

[0038] After the adsorption layer has desorbed and rotated downwards, the L-shaped magnetic plate 12 can move to the bottom and sides of the metal hanging plate 11 to seal the adsorption layer. At this time, the adsorption capacity of the adsorption module 24 can be tested. The water pump 27 can draw water from the water storage tank 4 upwards through the corrugated pipe 28 and deliver it to the water supply pipe 29. The atomizing nozzle 30 can spray water mist upwards, and the adsorption module 24 can adsorb the water mist. When adsorbing water mist, the weight of the adsorption module 24 will increase, thereby stretching the force spring 26 and increasing the data collected by the pressure sensor 25. The main control unit 16 can determine the adsorption capacity of each adsorption module 24 based on the data collected by the pressure sensor 25. When the adsorption capacity is poor, the staff can be notified in time to take appropriate measures.

[0039] Preferably, the self-testing mechanism includes a limiting cylinder 31 and a telescopic rod 32. The limiting cylinder 31 is disposed on the top and bottom surfaces of the rotating column 8. The pressure sensor 25 is located in the limiting cylinder 31. The force spring 26 is located in the limiting cylinder 31 and connected to the pressure sensor 25. One end of the telescopic rod 32 extends into the limiting cylinder 31 and is connected to the force spring 26, and the other end is connected to the adsorption module 24.

[0040] To ensure the accuracy of the data collected by the pressure sensor 25, the force spring 26 is placed in the limiting cylinder 31. When the adsorption module 24 adsorbs water mist, the gravity increases and pulls the force spring 26 through the telescopic rod 32. The limiting cylinder 31 can limit the movement of the telescopic rod 32 to avoid deviation and ensure the accuracy of data collection.

[0041] Preferably, the self-testing mechanism further includes a vertical electric slide 33, a horizontal electric slide 34, a second electric push rod 35, a lifting plate 36, and a strain gauge 37. The vertical electric slide 33 is disposed on the upper surface of the L-shaped magnetic plate 12, and its top surface of the mover is connected to the bottom surface of the horizontal electric slide 34. The second electric push rod 35 is disposed on the top surface of the mover of the horizontal electric slide 34, and its output shaft is connected to the bottom surface of the lifting plate 36. The strain gauge 37 is disposed on the top surface of the lifting plate 36. The main control unit 16 is electrically connected to the vertical electric slide 33, the horizontal electric slide 34, the second electric push rod 35, and the strain gauge 37.

[0042] In addition to adsorbing the adsorption capacity of the adsorption module 24, this invention can also determine whether hot spots have formed on the photovoltaic panel 1. When there is shading or failure on the photovoltaic panel 1, hot spots will form, causing abnormal desorption temperature of the adsorption layer in the corresponding area. Because the desorption effect of the adsorption module 24 is different in different areas, when the adsorption layer desorbs to a certain extent, the adsorption layer can be rotated downwards, and then the bottom surface and both sides of the metal pendant plate 11 are sealed by the L-shaped magnetic plate 12. At this time, the vertical electric slide 33 and the horizontal electric slide 34 can be driven to move, so that the first The second electric actuator 35 moves the lifting plate 36 and strain gauge 37 to different adsorption modules 24. The second electric actuator 35 drives the lifting plate 36 to rise, so that the strain gauge 37 contacts the bottom surface of the adsorption module 24 and pushes the adsorption module 24 to rise. The adsorption modules 24 with different desorption degrees have different volumes and thicknesses. The difference in data generated by the strain gauge 37 can be used to determine the degree of desorption of the adsorption modules 24 at different positions, thereby assessing whether there is a shaded area in the photovoltaic panel 1, so as to remove the shaded area in time and improve the photoelectric conversion efficiency of the photovoltaic panel 1.

[0043] Preferably, the multi-module adsorption mechanism further includes a hydraulic rod 38, which is disposed on both sides of the water storage tank 4, and its output shaft is connected to the bottom end of the support rod 6. The main control unit 16 is electrically connected to the hydraulic rod 38.

[0044] The hydraulic rod 38 is used to raise and lower the support rod 6 and adjust the position of the rotating column 8 so as to replace the position of the first adsorption layer 9 and the second adsorption layer 10.

[0045] Preferably, the multi-module adsorption mechanism further includes a wireless transmission module 39, which is disposed on the outer wall of the support rod 6, and the main control unit 16 is connected to the wireless transmission module 39 for data transmission.

[0046] The wireless transmission module 39 can send information to staff at a distance to indicate whether the adsorption module 24 has decreased adsorption capacity and whether the photovoltaic panel 1 is obstructed, so that timely handling can be carried out.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
