Description

Background Art

[0002] As the water shortage problem caused by global climate change and population growth becomes increasingly serious, finding new water sources has become one of the key ways to solve this problem. Atmospheric Water Generation (AWG) technology, as an innovative means of obtaining water resources, has attracted widespread attention because it can provide drinking water without relying on surface or groundwater. Among them, adsorption-based air water generation is a technology that extracts water vapor from the atmosphere through highly efficient water-absorbing materials and converts it into usable fresh water.

[0003] However, the related technology of using solar radiation energy as a driving force for adsorption-type air water extraction often has the following technical problems: although the adsorption material can achieve the adsorption of water vapor, the adsorption efficiency is poor; at the same time, the efficient use of solar energy is not fully considered, resulting in low energy conversion efficiency.

[0037] With global climate change and population growth, water shortage is becoming more and more serious, and finding new water sources has become an urgent problem to be solved. Among the many means of obtaining water resources, atmospheric water generation (AWG) technology has gradually attracted attention due to its unique advantages. This technology can extract water vapor from the atmosphere and convert it into fresh water without relying on surface or groundwater, providing a new idea for solving the problem of water shortage.

[0038] Adsorption air water extraction technology is a type of AWG technology, which mainly uses high-efficiency water-absorbing materials to capture and convert water vapor in the atmosphere. However, the related adsorption air water extraction technology has the following problems in its application: although the existing adsorption materials can achieve the adsorption of water vapor, their adsorption efficiency is generally low, resulting in poor overall water extraction efficiency; in the adsorption air water extraction process, solar radiation energy is used as the driving force, but the related technology fails to fully consider the efficient use of solar energy, resulting in low energy conversion efficiency.

[0039] In order to solve all or part of the technical problems in the above-mentioned related technologies, in an exemplary embodiment of the present disclosure, firstly, an adsorption-type air water extraction system driven by solar energy is provided. Figure 1 The schematic diagram of the structure of a solar-driven adsorption air water extraction system according to some embodiments of the present disclosure is shown. Figure 1 As shown, the solar-driven adsorption air water extraction system may include a solar module 1, a battery 2, an adsorption bed 3, an electric heater 4, a condensation chamber 5, a semiconductor refrigerator 6, a water collector 7 and a humidity sensor 8. The battery is used to store the electric energy generated by the solar module; the adsorption bed includes an adsorption material, which is used to absorb moisture from the air and store the moisture in the adsorption material; the electric heater is electrically connected to the battery and is used to heat the adsorption bed to obtain water vapor; the condensation chamber includes an air inlet end, and the condensation chamber is used to condense the water vapor to convert the water vapor into liquid water; the semiconductor refrigerator is electrically connected to the battery and is used to condense the air in the condensation chamber to obtain liquid water; the water collector is used to collect liquid water; the humidity sensor is arranged on the delivery pipeline between the adsorption bed and the condenser, and is used to detect the humidity of the gas in the delivery pipeline; when the humidity of the gas in the delivery pipeline is less than the preset humidity threshold, the battery stops supplying power to the electric heater.

[0040] The solar module may refer to a device for directly converting solar radiation into electrical energy, such as a photovoltaic panel or a solar thermal panel. The storage battery may be used to store the electrical energy generated by the solar module, thereby continuously supplying power to the water intake system. For example, the storage battery may be a lithium-ion battery, a lead-acid battery, a nickel-cadmium battery, etc.

[0041] The adsorption bed refers to a device that can absorb moisture from the air. Exemplarily, the adsorption bed can be composed of an adsorption material, a container, an air inlet and an exhaust port, a distributor, and an insulation layer. Among them, the adsorption material is the core component of the adsorption bed, and its main function is to absorb moisture from the air. The adsorption material can be silica gel, molecular sieves (such as zeolite), activated carbon, metal organic framework materials (MOFs), etc. The container is used to load the adsorption material and provide a channel for air circulation. The two ends are provided with an air inlet and an exhaust port, which can be made of stainless steel, plastic or other corrosion-resistant materials. The air inlet is used to introduce outside air, and the exhaust port is used to discharge air that has been treated by the adsorption bed. In addition, the air inlet and the exhaust port can be equipped with valves and filters to prevent external impurities from entering the interior of the adsorption bed while ensuring smooth air flow. The distributor is used to evenly distribute the air entering the adsorption bed to ensure that the air is fully in contact with the adsorption material. Exemplarily, the distributor can be a porous plate structure, a grid structure or other suitable distributor structure. The insulation layer is used to reduce the heat loss of the adsorption bed during the heating process and improve the thermal efficiency of the system. It is wrapped around the outer wall of the adsorption bed and can be composed of insulation materials such as rock wool and polyurethane foam.

[0042] The electric heater can be used to heat the adsorbent material in the adsorption bed, thereby prompting the adsorbent material to release the adsorbed moisture. Exemplarily, the electric heater can be composed of a heating element, an insulating material, a housing, an electrical connector and a temperature control device. Among them, the heating element is used to convert electrical energy into thermal energy, which can be a resistance wire (such as a nickel-chromium alloy wire), a heating tube, a heating belt, a heating plate, etc. The insulating material is used to protect the heating element, prevent current leakage, and ensure that the temperature around the heating element can reach the required level. The housing is used to protect the heating element and the insulating material, and provide an installation location. The electrical connector is used to connect the heating element to a power source. The temperature control device is used to monitor the operating temperature of the heating element and cut off the power supply when necessary to prevent overheating.

[0043] The condensation chamber refers to a component for cooling the water vapor released after heating by the electric heater into liquid water. Exemplarily, the condensation chamber can be composed of a shell, a heat exchanger, an air inlet and a water outlet. Among them, the heat exchanger is a key component for exchanging heat in the condensation chamber, and the water vapor is cooled into liquid water by heat exchange with the air. The air inlet is used to introduce gas containing water vapor emitted from the adsorption bed. The water outlet is used to discharge the condensed liquid water.

[0044] Semiconductor refrigerators may refer to devices that use the Peltier Effect for cooling. In air water extraction systems, semiconductor refrigerators may be used to reduce the temperature in the condensation chamber and accelerate the condensation process of water vapor. Water collectors may refer to devices for collecting and storing liquid water. Humidity sensors may refer to components for detecting the humidity of gas in the transport pipeline between the adsorption bed and the condenser.

[0045] In actual operation, at night, the adsorption bed is responsible for absorbing water, and the adsorption material of the adsorption bed absorbs the water in the air and stores it inside. During the day, the solar panel is responsible for converting solar energy into electrical energy, and storing the electrical energy generated by the solar panel through the battery. When it is necessary to desorb the water in the adsorption bed, the electric heater heats the adsorption bed with the electric energy provided by the battery, so that the water in the adsorption material evaporates into water vapor. After the water vapor enters the condensation chamber, it is cooled to below the condensation point through heat exchange with the cooling medium and converted into liquid water. In order to accelerate the condensation process, the semiconductor refrigerator provides additional cooling effect to reduce the temperature in the condensation chamber, thereby improving the condensation efficiency. The condensed liquid water is collected at the bottom of the condensation chamber and flows into the water collector through the pipe for storage. In addition, the humidity sensor is installed on the transmission pipeline between the adsorption bed and the condensation chamber to monitor the gas humidity in real time. When the humidity is lower than the preset threshold, the humidity sensor sends a signal to the control system, which then stops the operation of the electric heater to save energy.

[0046] Specifically, in order to improve the water extraction efficiency of the solar-driven adsorption air water extraction system, the condensation air water extraction method can be combined with the adsorption-desorption air water extraction method. At night, because the adsorption bed needs to absorb water and the solar energy component cannot convert electricity, the energy consumption of the electric heating component is also high, so only the adsorption-desorption air water extraction is performed. During the day, the condensation air water extraction method and the adsorption-desorption air water extraction method are combined to improve the water extraction efficiency.

[0047] Furthermore, at night, the adsorbent material in the adsorption bed begins to adsorb water vapor from the air. In this stage, no adsorption-desorption air water extraction is performed, but water is accumulated for the subsequent desorption process. At the same time, the semiconductor refrigerator is running, and by adjusting the refrigeration temperature to a temperature lower than the condensation temperature of water, the water vapor in the air can be condensed to obtain liquid water. In addition, the current flowing through the semiconductor refrigerator can be adjusted based on the current air humidity, so that the semiconductor cooling sheet is in the best working state and energy saving is achieved.

[0048] During the day, the adsorption bed is heated to desorb water vapor from the adsorption material. The desorbed water vapor passes through the condensation chamber and is condensed into liquid water using a semiconductor refrigeration system. By adjusting the current flowing through the semiconductor, the condensation temperature is kept within a suitable range to improve water extraction efficiency. The humidity sensor monitors the air humidity at the outlet of the adsorption bed in real time. When the humidity is lower than a preset threshold (e.g., 20% relative humidity), the control system will stop the power supply to the electric heater to save energy.

[0049] In the example embodiment of the present disclosure, the adsorption-type air water extraction system based on solar energy drive can realize condensation-type air water extraction by using semiconductor refrigerators, and can realize adsorption-desorption-type air water extraction by using adsorption beds and electric heaters. Combining the two can improve the practicality and stability of the air water extraction system; on the other hand, when the humidity of the gas in the transmission pipeline is less than the preset humidity threshold, it means that the water vapor content in the adsorption bed is low. If the adsorption-desorption-type air water extraction is continued, the water extraction efficiency is poor and the energy consumption is high. Therefore, it is necessary to stop supplying power to the electric heater and only use the semiconductor refrigerator for condensation-type air water extraction to improve the water extraction efficiency and reduce energy consumption; on the other hand, by combining the adsorption-desorption technology and the condensation-type water extraction technology, the system can maintain a high water extraction efficiency under different climatic conditions. In an environment with high humidity, the adsorption material can effectively capture moisture; and in the case of low humidity, water can be directly condensed from the air by the semiconductor refrigerator to ensure that sufficient liquid water can be obtained under various weather conditions. Even when the solar energy is not enough to support the operation of the electric heater, the system can still operate independently through the semiconductor refrigerator to ensure a stable water supply on cloudy days and other bad weather. Thereby, the efficiency and stability of the solar-driven adsorption air water extraction process are improved to a certain extent.

[0050] Next, the solar-driven adsorption air water extraction system in the above exemplary embodiment will be further described.

[0051] In some embodiments, the semiconductor refrigerator includes: a cooling end; a heat release end; and a plurality of thermocouple pairs, wherein the thermocouple pairs include an N-type semiconductor and a P-type semiconductor, and the N-type semiconductor and the P-type semiconductor are disposed between the cooling end and the heat release end.

[0052] Among them, the semiconductor refrigerator can be referred to as a device that uses the Peltier effect for cooling. The semiconductor refrigerator does not require a refrigerant and has the advantages of light weight, low noise, and high temperature control accuracy. It can include multiple thermocouple pairs, and the thermocouple pairs are composed of N-type semiconductors and P-type semiconductors. When the semiconductor refrigerator is powered on, the current flows from the N-type semiconductor to the P-type semiconductor joint to absorb heat, forming a cooling end 61, and the current flows from the P-type semiconductor to the N-type semiconductor joint to release heat, forming a heat release end 62. The degree of heat absorption and heat release depends on the size of the current and the number of pairs of N-type and P-type semiconductor elements. The Peltier effect of the semiconductor refrigerator can be as follows Figure 2 shown.

[0053] In some embodiments, the semiconductor refrigerator further includes: a heat dissipation component for cooling the heat release end.

[0054] Specifically, the heat dissipation component can refer to a device for removing heat from the heat release end. Exemplarily, the heat dissipation component can be an air-cooled heat dissipation component, which can be composed of a heat sink, a fan and a heat pipe. The heat generated at the heat release end is transferred to the heat sink through the heat pipe. The fan forces the air to flow and takes the heat away from the heat sink, thereby achieving cooling of the heat release end. The heat dissipation component can be a water-cooled heat dissipation component, which can be composed of a water circulation pipeline, a water pump and a heat exchanger. The circulating water is pushed by the water pump and flows in the water circulation pipeline. The heat generated at the heat release end is transferred to the circulating water through the heat exchanger. The output end of the water circulation pipeline is connected to the water collector, and the heat is taken away by the liquid water in the water collector. Of course, in other embodiments of the present disclosure, the heat dissipation component can also be a structure of other forms.

[0055] Furthermore, the temperature of the cooling end needs to be controlled during the operation of the semiconductor refrigerator, and there is usually no specific requirement for the temperature of the heat release end. However, when the semiconductor refrigerator is in operation, the temperature of the cooling end is much lower than that of the heat release end, and heat conduction will cause the heat of the heat release end to be transferred to the cooling end, thereby affecting the refrigeration performance. In order to ensure that the semiconductor refrigerator maintains a low temperature at the cooling end during long-term operation and to keep the semiconductor refrigerator in the best working state, it is necessary to ensure that the heat release end has a good heat dissipation environment and continuously dissipates the heat from the cooling end to the outside world. Therefore, in addition to the performance of the semiconductor refrigerator itself, the heat dissipation effect of the heat release end is also the key to ensuring the efficient operation of the refrigeration plate. Taking effective heat dissipation measures at the heat release end is an important link in ensuring the optimal operating state of the semiconductor refrigerator.

[0056] In some embodiments, reference Figure 1 As shown, the heat dissipation component includes: a water circulation pipeline 63, the input end and the output end of the water circulation pipeline are connected to the water collector, and are used to cool the heat release end through the liquid water in the water collector.

[0057] Specifically, the liquid water in the water collector is introduced to the heat release end through the water circulation pipeline. The large heat capacity and good thermal conductivity of the liquid water can effectively absorb the heat generated by the heat release end and improve the refrigeration efficiency. The liquid water in the water collector is used for heat exchange, and water resources can be recycled to avoid the consumption of a large amount of water resources.

[0058] In some embodiments, reference Figure 2 As shown, the heat dissipation component also includes: an air box 64, the input end of which is connected to the condensation chamber, and is used to cool the heat release end using the cooling gas in the condensation chamber; wherein the output end of the air box is connected to the adsorption bed, and is used to input the heated cooling gas into the adsorption bed.

[0059] Specifically, the cooling gas in the condensation chamber is guided to the heat release end through the input end of the gas box, and the low temperature characteristics of the gas are used to absorb the heat at the heat release end, thereby improving the refrigeration efficiency. After the cooling gas absorbs heat at the heat release end, the temperature rises, and then it is transported to the adsorption bed through the output end of the gas box, thereby realizing the effective transfer of heat. After the cooling gas is cooled in the condensation chamber, it is transferred to the heat release end through the gas box to absorb heat, and then it is transported to the adsorption bed, thereby realizing the recycling of the cooling gas and reducing the need for additional cooling resources. Using the cooling gas inside the system for heat exchange can reduce the energy consumption of the system. The heated cooling gas is transported to the adsorption bed through the output end of the gas box, thereby providing an additional heat source for the heating process of the adsorption bed and optimizing the heating process of the adsorption bed.

[0060] In some embodiments, the above-mentioned solar-powered adsorption air water extraction system may also include: a liquid level sensor, arranged in the water collector, for measuring the liquid level of liquid water in the water collector; wherein, when the liquid level is lower than a preset liquid level threshold, the liquid water in the water collector does not flow into the water circulation pipeline.

[0061] Specifically, the water circulation pipeline needs enough water to effectively remove the heat from the hot end of the semiconductor. If the water volume is insufficient, the water circulation pipeline will not work properly, resulting in too high a temperature at the hot end of the semiconductor, affecting the cooling effect and water extraction efficiency. In addition, the water circulation pipeline uses water from the water collector. If the water circulation pipeline is started when there is insufficient water, it will lead to a waste of water resources. By detecting the water level with a liquid level sensor, it can be ensured that the water circulation pipeline is only started when there is sufficient water, thereby saving water resources. If the water circulation pipeline is started when there is insufficient water, the water pump may run idle and damage the water pump equipment.

[0062] In some embodiments, reference Figure 3 As shown, the adsorbent material may include a plurality of air channels 31, and the air channels run through the adsorbent material. The presence of the air channels can improve the distribution of the airflow in the adsorbent material, ensure that the air can pass through the adsorbent material evenly, and improve the adsorption efficiency. The air channels increase the contact area between the air and the adsorbent material, reduce the resistance to gas flow, and enable more moisture to be captured by the adsorbent material. The presence of the air channels helps to evenly distribute the heated air during the desorption process, ensuring that the moisture in the adsorbent material can be evenly heated and released.

[0063] In some embodiments, the input current of the semiconductor refrigerator can be adjusted according to the following formula to improve the cooling efficiency of the semiconductor refrigerator.

[0064] ; in, Represents the input current of the semiconductor cooler, Indicates the cooling end temperature of the bulk cooler, Indicates the temperature of the heat release end of the body cooler, represents the Seebeck coefficient, represents the resistance of the body cooler, Z represents a constant, Indicates the difference between the temperature at the heat release end and the temperature at the cooling end.

[0065] Specifically, the cooling efficiency of the semiconductor refrigerator is proportional to the DC current passing through it. When the current increases, the lowest cooling temperature that the semiconductor refrigerator can reach will also decrease accordingly. When the cooling temperature is higher than the dew point temperature, condensation will not occur; once the cooling temperature is lower than the dew point temperature, condensation will occur. If the working current of the semiconductor refrigerator is too high and the temperature at the cooling end drops below 0°C, ice crystals will form or even freeze. In this case, the condensed water cannot be collected and energy will be wasted. Therefore, it is necessary to adjust the input current of the semiconductor refrigerator to optimize the cooling efficiency of the semiconductor refrigerator.

[0066] In the above-mentioned embodiment, the adsorption air water extraction system based on solar energy drive can realize condensation air water extraction by using semiconductor refrigerators, and can realize adsorption desorption air water extraction by using adsorption beds and electric heaters. Combining the two can improve the practicality and stability of the air water extraction system; on the other hand, when the humidity of the gas in the transmission pipeline is less than the preset humidity threshold, it means that the water vapor content in the adsorption bed is low. If adsorption desorption air water extraction is continued, the water extraction efficiency is poor and the energy consumption is high. Therefore, it is necessary to stop supplying power to the electric heater and only use semiconductor refrigerators for condensation air water extraction to improve water extraction efficiency and reduce energy consumption; on the other hand, by combining adsorption desorption technology and condensation water extraction technology, the system can maintain a high water extraction efficiency under different climatic conditions. In an environment with high humidity, the adsorption material can effectively capture moisture; and in the case of low humidity, water can be condensed directly from the air through semiconductor refrigerators to ensure that sufficient liquid water can be obtained under various weather conditions. Even when solar energy is insufficient to support the operation of the electric heater, the system can still operate independently through semiconductor refrigerators, ensuring a stable water supply on cloudy days and other bad weather. Thereby, the efficiency and stability of the solar-driven adsorption air water extraction process are improved to a certain extent.

[0067] In addition, by using multiple thermocouple pairs, the semiconductor refrigerator can effectively transfer heat from the cooling end to the heat release end, thereby achieving efficient cooling. The heat dissipation component can effectively cool the heat release end to prevent the cooling efficiency from decreasing due to heat accumulation. By timely removing the heat from the heat release end, the heat dissipation component helps to maintain the thermal balance of the system and improve the stability and reliability of the system. The water circulation pipeline cools the heat release end through the liquid water in the water collector, realizing the recycling of heat energy and further improving the energy efficiency of the system. Using the collected liquid water as a cooling medium reduces the dependence on the external cooling system and reduces energy consumption. By guiding the cooling gas in the condensation chamber to the heat release end for cooling, and then returning the heated gas to the adsorption bed, not only the cooling capacity of the condensation chamber is improved, but also the heat required for the heating process is reduced, realizing the effective transfer of temperature. The liquid level sensor can monitor the liquid level in the water collector in real time. When the liquid level is lower than the preset threshold, it prevents liquid water from flowing into the water circulation pipeline, thereby avoiding the waste of water resources.

[0068] Next, in the embodiment of the present disclosure, an adsorption-type air water extraction method based on solar energy drive is also provided. Figure 4 The schematic diagram shows a process flow diagram of a solar-driven adsorption air water extraction method according to some embodiments of the present disclosure. Figure 4 As shown, the solar-driven adsorption air water extraction method may include the following steps: Step S410, determining the adsorption material in the adsorption bed based on simulation verification under multi-physical field coupling; Step S420, storing the electric energy generated by the solar panel in a storage battery, and supplying power to the electric heater and the semiconductor refrigerator through the storage battery; Step S430, when the humidity of the output gas of the adsorption bed is greater than a preset humidity threshold, the adsorption bed is heated by an electric heater to obtain water vapor, and the water vapor is condensed by a condensation chamber to convert the water vapor into liquid water; Step S440, using a semiconductor refrigerator to condense the air in the condensation chamber to obtain liquid water; Step S450, collecting liquid water.

[0069] Among them, multi-physics coupling can represent the interaction of multiple physical fields such as thermodynamics, fluid mechanics, and chemical adsorption. In actual operation, multi-physics simulation software (such as COMSOL Multiphysics, ANSYS Fluent, etc.) can be used to establish a mathematical model of the adsorption bed. The model can be established based on the physical properties of the adsorbent material (such as porosity, specific surface area, etc.), adsorption kinetics (adsorption rate, adsorption amount, etc.), thermodynamic behavior (adsorption heat, temperature effect, etc.) and fluid mechanics (gas flow, pressure drop, etc.). Specifically, the fluid mechanics simulation verifies the flow of the simulated gas in the adsorption bed, the thermodynamic simulation verifies the temperature change during the adsorption process, including heat release during adsorption and heat absorption during desorption, and the adsorption kinetics simulation verifies the interaction between the simulated adsorbent material and the gas molecules, including adsorption capacity, adsorption rate, etc. Different types of adsorbent materials (such as silica gel, molecular sieves, activated carbon, etc.) are simulated and tested. The performance of the adsorbent material under different environmental conditions (temperature, humidity, air flow velocity, etc.) is analyzed. The optimal adsorption material combination is determined through the simulation results to ensure the highest adsorption efficiency and stability in practical applications. Finally, the obtained optimal adsorption material combination is used as the adsorption material in the adsorption bed to improve the adsorption efficiency.

[0070] In actual operation, at night, the adsorption bed is responsible for absorbing moisture from the air, and the adsorption material in the adsorption bed captures the moisture in the air and stores it inside. During the day, the solar panel converts solar energy into electrical energy and stores the electrical energy generated by the solar panel through the battery. When it is necessary to desorb the moisture in the adsorption bed, the electric heater heats the adsorption bed with the electrical energy provided by the battery, so that the moisture in the adsorption material evaporates into water vapor. The water vapor then enters the condensation chamber and is cooled below its condensation point through heat exchange with the cooling medium, turning into liquid water. In order to accelerate the condensation process, the semiconductor refrigerator provides additional cooling effect to reduce the temperature in the condensation chamber, thereby improving the condensation efficiency. The condensed liquid water is collected at the bottom of the condensation chamber and flows into the water collector through the pipe for storage. In addition, the humidity sensor is installed on the transmission pipeline between the adsorption bed and the condensation chamber to monitor the gas humidity in real time. When the humidity is lower than the preset threshold, the humidity sensor sends a signal to the control system, which then stops the operation of the electric heater to save energy.

[0071] Next, the solar-driven adsorption air water extraction method in the above exemplary embodiment will be further described.

[0072] In some embodiments, the adsorption material in the adsorption bed is determined based on simulation verification under multi-physical field coupling, which specifically includes the following steps: determining the unit water absorption mass and water absorption rate corresponding to a plurality of candidate materials; determining the adsorption material from the candidate materials according to the unit water absorption mass and water absorption rate; performing fluid mechanics simulation verification, thermodynamic simulation verification and adsorption kinetics simulation verification on the adsorption material to obtain simulation verification results under multi-physical field coupling; and verifying the adsorption performance of the adsorption material according to the simulation verification results.

[0078] Then, fluid mechanics simulation software (such as ANSYS Fluent, CFD, etc.) is used to establish a gas flow model in the adsorption bed, considering the velocity distribution and pressure distribution of the gas, setting reasonable boundary conditions, simulating the gas flow in the actual working environment, analyzing the performance of different materials in the gas flow, and evaluating their fluid mechanics properties.

The simulation results of fluid mechanics, thermodynamics and adsorption kinetics are comprehensively analyzed to evaluate the comprehensive performance of different materials under the coupling of multiple physical fields. The performance of different materials in fluid mechanics, thermodynamics and adsorption kinetics is compared to determine the most suitable adsorption material for the adsorption bed.
