[0002] Water is the source of life. With the dramatic changes in the earth's environment, many areas have experienced severe desertification. About two-thirds of the world's population suffers from freshwater shortages in a year, and about 500 million people face serious water shortages throughout the year, which not only affects the lives and livelihoods of the population, but is also extremely detrimental to the growth of plants and animals. Therefore, it is imperative to develop new sustainable water extraction technologies.

[0003] Metal organic framework (MOF) is a common hygroscopic material that captures moisture from the air through its strong adsorption capacity. After adsorption saturation, the moisture adsorbed by MOF is released and collected by heating or decompression, which can effectively solve the current problem of lack of fresh water resources. However, studies have shown that there are few existing technologies for using MOF as a water-absorbing material in the field of water extraction equipment. The adsorption and desorption cycles are long, the efficiency of collecting moisture is low, and it cannot work for a long time in harsh environments, making it difficult to promote and apply.

[0047] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, rather than all the embodiments.

[0048] Reference Figure 1-12 , automatic water collection device equipped with MOF porous carrier, reference Figure 1-12 As shown, in some embodiments, an automatic water collection device equipped with a MOF porous carrier is mainly composed of a photovoltaic system 1, a buffer system 2, a temperature control system 3, and a water collection system 7.

[0049] Photovoltaic system 1

[0050] The photovoltaic system 1 is composed of solar panels and batteries. The batteries and the control panel 41 are assembled into a temperature controller, which converts light energy into electrical energy and stores it inside the battery to provide power supply for the temperature control system 3.

[0051] Specifically, refer to Figure 1 As shown, the battery is stored in the temperature control system 3. By always placing one side of the solar panel facing the sun, light energy is converted into electrical energy, providing a continuous supply of power support for the temperature control system 3.

[0052] Buffer system 2

[0053] refer to Figure 1-3As shown, the buffer system 2 is mainly composed of a buffer box 37 and a heat sink 5. The interior of the buffer box 37 is designed as an arc-shaped water collection buffer tank 9, and three groups of air vents 10 are opened at the bottom. Each group of air vents 10 is provided with a cross ring 8, which is fixed above the air vent 10 by screws 38; wherein, the heat sink 5 adopts an insert-type heat sink, which is fixed above the water collection buffer tank 9 by a shielded and embedded manner, and is further locked by a fixing pin 34.

[0054] During the specific implementation process, the tube sleeve 39 is put on the end of the semiconductor hot and cold tube 13, and the cross ring 8 is fixed on the vent 10 by the screw 38 to fix the position of the MOF water collecting tube 6; the tooth thickness of the heat sink 5 is 1mm, the tooth pitch is 5mm, and the material is selected from copper. It is fixed on the top of the buffer box in a shielded embedded manner to avoid direct sunlight exposure. It will form a three-dimensional cooling space with the buffer tank 9, the inner wall of the buffer box 37 and the vent 10, and establish mutual connection with the water collection system 7; the cooling space collects the water molecules desorbed from the MOF porous carrier 40, and dissipates part of the heat of the gaseous water molecules to the surrounding environment through the heat sink 5, so that the cooled water molecules converge to the refrigeration surface 45 of the condenser 27, thereby assisting the water molecules to complete the steps of nucleation, growth, aggregation and gravity dehydration.

[0055] Temperature control system 3

[0056] refer to Figure 1 , 7 As shown in Figures 8, 9 and 10, the temperature control system 3 is mainly composed of a control panel 41, a first temperature sensor 31, a second temperature sensor 32 and a semiconductor cold and hot tube 13, and is powered by the photovoltaic system 1; the first temperature sensor 31 and the second temperature sensor 32 use thermocouple sensors, and the probes are pre-buried in the heating surface 28 and the cooling surface 45 of the semiconductor cold and hot tube 13, respectively.

[0057] In some embodiments, the control panel 41 uses the temperature information fed back by the first temperature sensor 31 and the second temperature sensor 32 to monitor the ambient temperature of the MOF water collection tube 6 in real time, and at the same time, the control panel 41 intermittently provides power to the semiconductor cold and hot pipe 13 to realize the automatic adjustment of the internal environment of the MOF water collection tube 6, improve the efficiency of water vapor liquefaction inside the round insulating thermal conductive ceramic condenser 27, and at the same time, the round insulating thermal conductive ceramic heating pipe 30 can assist the MOF porous carrier 40 in absorbing and releasing water at ambient temperature. Among them, the intermittent working cycle of the semiconductor cold and hot pipe 13 is 2 hours / time, which not only prolongs the service life of the semiconductor material, but also further improves the water collection efficiency.

[0058] In the specific implementation process, the cooling power of the semiconductor hot and cold tube 13 is 80W, the rated voltage is 10V, and the assembly pressure is 80N / cm 2, the working environment temperature is -55-100℃. Among them, the semiconductor cold and hot tube 13 uses a copper conductive sheet 29 with high thermal conductivity to connect the N-type semiconductor 42 and the P-type semiconductor 43 into a tube body, and at the same time, one end of the N-type semiconductor 42 and the P-type semiconductor 43 are respectively connected to the positive and negative poles of the DC power supply of the temperature control system 3 to form an electric couple. Using the Peltier effect, when electrons flow from the low-energy P-type semiconductor 43 to the high-energy N-type semiconductor 42, the electrons will jump from the low energy level to the high energy level, which is manifested as electrons absorbing heat, forming a round insulated thermal conductive ceramic condenser 27, which can further increase the liquefaction rate of water vapor, and converge into the water collection bottle 36 through the guide tube 19 to complete the water collection work. On the contrary, when electrons flow from the high-energy N-type semiconductor 42 to the low-energy P-type semiconductor 43, the electrons will jump from the high energy level to the low energy level, which is manifested as electron heat release, forming a round insulated thermal conductive ceramic heating tube 30, which can assist the MOF water collection tube 6 in intermittently heating and desorbing water molecules in the low temperature environment of the desert at night.

[0059] Water collection system7

[0060] refer to Figure 1 , 4 As shown in FIGS. 5, 6, 7, 8, 9, 10, 11 and 12, the water collection system 7 is provided with 3 groups of MOF water collection cylinders 6 and 3 groups of water collection bottles 36, and each group of MOF water collection cylinders 6 is composed of a vacuum insulation double-walled glass tube 21 and a MOF water collection unit 11. Among them, the MOF water collection unit 11 is provided with a unit frame 14, a MOF water collection sheet 15 and a high thermal conductivity porous sheet 16.

[0061] In the specific implementation process, the MOF porous carrier 40 in the MOF water collection sheet 15 is prepared by the mixed solvent in-situ growth method of MIL-100 (Fe). The principle is to use transition metal ions as nodes and organic ligands as supports to extend into a 3D spatial network structure to form a microporous pore structure with strong adsorption force for water molecules. The preparation process is as follows:

[0062] First, weigh 3.39 g of FeCl2·4H2O and pour it into 145.8 g of deionized water. Use a glass rod to slowly stir for 30 min until it is completely dissolved to form solution a. Set aside.

[0063] Secondly, slowly pour 2.514g of trimesic acid into 34.14g of deionized water, and then slowly pour 1.437g of NaOH solution to adjust the pH value of the reaction system to further promote the reaction, and at the same time adjust the reaction rate and product distribution. Finally, slowly stir the mixture with a glass rod until it is completely dissolved to form solution b for later use;

[0064] Secondly, slowly pour solution a into solution b, put it into a magnetic stirring pot at a rate of 1200 rpm and stir until it is completely mixed and set aside;

[0065] Secondly, the mixed solution was transferred to a high-pressure reactor, and a clean surface honeycomb ceramic sheet with an outer diameter of 50 mm, an inner diameter of 20 mm, a thickness of 1 mm was placed at 60 degrees with the bottom of the bottle and completely immersed in the mixed solution, so that the solution in the later reaction could more easily grow the MOF porous carrier evenly in situ on the surface of the honeycomb ceramic sheet. After sealing, the high-pressure reactor was placed in an oven at 120°C for 24 hours of heating.

[0066] Once again, after the reaction is completed, the honeycomb ceramic sheet immersed in the mixed solution is taken out, immersed in 200 ml of deionized water for 12 hours, and then taken out and immersed in anhydrous ethanol for 12 hours to clean the excess impurities. After the reaction is completed, the cleaned modified honeycomb ceramic sheet is placed in an oven and dried for 24 hours, so that the purified MIL-100 (Fe) is activated, and the activated MOF water collection sheet 15 can be obtained.

[0067] In some embodiments, three rectangular guardrails are arranged around the unit frame 14, and the material is selected from PLA and is made by 3D printing; wherein, the high thermal conductivity porous sheet 16 is made of foam copper, with a thickness of 3mm, a porosity of 93%, a pore diameter of 1mm, a semi-outer diameter of 50mm, and an inner diameter of 20mm. In the specific operation process, refer to Figure 7 As shown, the MOF water collection sheet 15 and the high thermal conductivity porous sheet 16 are sequentially cross-crossed through the semiconductor cold and hot tubes 13 and stacked and fixed on the unit frame 14, which not only allows the external air to flow and diffuse along the high pore structure of the high thermal conductivity porous sheet 16, so that the surface of the MOF porous carrier 40 is completely exposed to the air and fully absorbs moisture, but also can use the high thermal conductivity performance of the high thermal conductivity porous sheet 16 as a heat conductor between the MOF porous carriers 40 under the sun to improve the desorption capacity of moisture. After the stacking is completed, the front protective cover 35 at the front end and the stopper 20 at the rear end are used to limit the position to form the MOF water collection unit 11, and the groove foot 18 is inserted into the groove eye 24 of the bell-shaped wind head 12, and then the vacuum insulation double-walled structure glass tube 21 is rotated and fixed along the thread 33 to form a heat preservation layer to prevent the heat loss to the environment under the sun, and promote the desorption of moisture by the MOF porous carrier 40.

[0068] Specifically, an air inlet 44 and an azimuth adjustment hole 23 are provided at the tail end of the trumpet-shaped wind head 12; the air inlet 44 draws the air from the surrounding environment into the interior of the MOF water collecting tube 6, and at the same time, the lighting angle of the MOF water collecting tube 6 can be adjusted through the azimuth adjustment hole 23, and the front and rear ends of the MOF water collecting tube 6 are aligned in the north-south direction, so that the surface of the MOF water collecting unit 11 always receives the light and heat from the sun rising in the east and setting in the west, and maximizes the use of the sun's projection area to complete the adsorption / desorption work.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
