Description

Technical Field

[0001] This disclosure relates to the field of seawater desalination technology, and in particular to an all-weather intelligent desalination device. Background Technology

[0002] With population growth and increasing environmental pollution, the shortage of freshwater resources has become one of the major threats to sustainable social development. Today, about 1.1 billion people worldwide are affected by severe freshwater shortages, making the development of efficient water purification technologies an urgent need. In the past few decades, people have tried various methods to obtain freshwater from seawater, collectively known as seawater desalination technology.

[0003] Currently, the mainstream seawater desalination equipment is based on reverse osmosis. Seawater passes through a pretreatment system, a reverse osmosis system, and a post-treatment system sequentially from the inlet to the outlet. Water transport consumes a significant amount of energy; components such as the suction pump and high-pressure pump require electricity, typically powered by burning fossil fuels, causing environmental pollution. The pretreatment system consists of multiple filters of varying precision to initially filter the incoming seawater, preventing damage to the reverse osmosis membrane from impurities. The reverse osmosis system includes a high-pressure pump, reverse osmosis membrane, and energy recovery device. The high-pressure pump provides high pressure to the seawater, helping it pass against its concentration gradient through the reverse osmosis membrane. The energy recovery device recovers energy from the high-pressure seawater for reuse. The post-treatment system includes water quality testing, pH adjustment, and disinfection devices. It tests the water quality after passing through the reverse osmosis membrane, adjusts the pH with reagents, and disinfects to meet drinking water standards. Some equipment is based on distillation, such as multi-stage flash distillation and multi-effect distillation technologies, which use solar energy to heat seawater for evaporation, and then condense the evaporated water to obtain freshwater.

[0004] Large-scale reverse osmosis systems require significant energy to transport water. Pumps, high-pressure pumps, and other water transport components all require electricity, typically generated from burning fossil fuels, leading to environmental pollution. Some smaller reverse osmosis units have built-in batteries and can be connected to external solar panels for photovoltaic power generation, but this is only suitable for daytime conditions with ample solar energy; it is ineffective at night or on cloudy days. Systems based on solar thermal distillation, such as traditional solar stills, multi-stage flash distillation, and multi-effect distillation, rely solely on solar energy. Even with the introduction of interfacial evaporation technology, insufficient solar energy means they cannot sustain continuous water evaporation. Summary of the Invention

[0005] In view of this, the present disclosure provides an all-weather intelligent desalination device, which at least partially solves the problems of the prior art that cannot meet the requirements of high-efficiency seawater desalination in all weather conditions and low desalination efficiency when solar energy is insufficient.

[0006] In a first aspect, embodiments of this disclosure provide an all-weather intelligent desalination device, comprising:

[0007] High-transparency top cover;

[0008] Solar energy storage devices;

[0009] The housing includes a first chamber and a second chamber for collecting fresh water.

[0010] The first chamber is equipped with several photothermal devices, and the several photothermal devices are respectively connected to the box body through several rotating shaft devices;

[0011] A raw water storage chamber is formed between several of the aforementioned photothermal devices and the bottom of the housing; an evaporation and condensation chamber is formed between several of the aforementioned photothermal devices and the high-permeability top cover;

[0012] The photothermal device includes a photothermal structure and a hydrophobic layer, a first hydrophilic layer, a second hydrophilic layer, and a third hydrophilic layer disposed on the outside of the photothermal structure. The first hydrophilic layer surrounds the periphery of the hydrophobic layer to form a first planar structure. The second hydrophilic layer is disposed perpendicular to the first planar structure. The third hydrophilic layer is connected to the second hydrophilic layer and forms a second planar structure.

[0013] Optionally, the solar energy storage device includes a solar panel, an energy storage component, and an electric heating component, with the solar panel covering the side of the housing;

[0014] The energy storage component is connected to the solar panel;

[0015] The electric heating component is disposed in the raw water storage chamber.

[0016] Optionally, the rotating shaft device includes a first connecting shaft, a second connecting shaft, and a drive motor, wherein the drive motor is mounted on the housing; one end of the first connecting shaft is fixedly connected to the power output end of the drive motor, and the other end is fixedly connected to one end of the photothermal device.

[0017] One end of the second connecting shaft is fixedly connected to the other end of the photothermal device, and the other end is connected to the housing.

[0018] Optionally, the longitudinal axis of the first connecting shaft and the longitudinal axis of the second connecting shaft are aligned with the longitudinal center axis of the photothermal device.

[0019] The longitudinal central axis of the photothermal device is perpendicular to the longitudinal axis of the housing.

[0020] Optionally, there are two second chambers, which are respectively located on both sides of the first chamber.

[0021] Optionally, the high-transparency top cover is sealed to the housing;

[0022] The high-transparency top cover includes a first inclined plate, a second inclined plate, and two parallel side plates, with the connection between the first inclined plate and the second inclined plate located above the first chamber;

[0023] The bottoms of the first inclined plate and the second inclined plate are respectively connected to the side walls of the two second chambers;

[0024] The periphery of the side plate is connected to the first inclined plate, the second inclined plate, and the box body, respectively.

[0025] Optionally, the width of the second chamber is smaller than the width of the first chamber.

[0026] Optionally, several of the aforementioned photothermal devices are arranged in parallel at equal intervals.

[0027] Optionally, the bottom of the housing is provided with multiple supports, which are evenly distributed.

[0028] Optionally, it also includes a central control center and a light intensity detection device, wherein the light intensity detection device and the rotating shaft device are both signal-connected to the central control center;

[0029] The light intensity detection device is used to detect the intensity of sunlight in real time;

[0030] The central control center controls the rotating shaft device to flip the first planar structure downwards based on the first range of light intensity detected by the light intensity detection device.

[0031] The central control center controls the rotating shaft device to flip the first planar structure upwards based on the second range of light intensity detected by the light intensity detection device.

[0032] The light intensity in the second range is greater than that in the first range.

[0033] The all-weather intelligent desalination device disclosed in this application, through the setting of the photothermal device, can be rotated and adjusted according to different light intensities to achieve faster evaporation efficiency. When there is sufficient sunlight during the day, the second plane structure of the photothermal device is oriented downwards (i.e., the hydrophobic layer is oriented upwards) via the rotating shaft device. Through the connection of the third hydrophilic layer, the second hydrophilic layer, and the first hydrophilic layer, a faster and stronger water absorption effect is formed, thus achieving rapid raw water transfer. During periods of insufficient sunlight during the day, the first plane structure of the photothermal device is oriented downwards (i.e., the hydrophobic layer is oriented downwards) via the rotating shaft device, which can maximize the concentration of heat in the thinner water layer on the upper surface, suppressing heat conduction loss to the water body below and promoting water evaporation. Alternatively, during periods of insufficient sunlight during the day, in addition to oriented the first plane structure of the photothermal device downwards (i.e., the hydrophobic layer is oriented downwards), stored electrical energy can be used to supply electric heat through an electric heating component to provide sufficient temperature for the photothermal structure, ensuring continuous and efficient water evaporation and greatly improving the desalination rate.

[0034] The all-weather intelligent desalination device disclosed in this application, during the day when there is sufficient sunlight, relies on interfacial evaporation technology to efficiently produce fresh water through the photothermal effect of water evaporation and condensation. The photovoltaic effect of the solar panels charges the storage battery. Simultaneously, the solar panels generate waste heat when exposed to sunlight, which can be recovered and reused to heat the water in the first chamber, promoting evaporation and improving desalination efficiency. At night when there is insufficient sunlight or on cloudy or rainy days, the electrical energy stored in the storage battery during the day is used to heat the water through the electrothermal effect of the electric heating components to continue water evaporation. It possesses all-weather water evaporation capability, high photothermal conversion efficiency, and water evaporation efficiency, enabling water evaporation under various weather conditions and achieving all-weather seawater desalination.

Detailed Implementation

[0042] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0043] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0045] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0046] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0047] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0048] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0049] Reference Figures 1 to 3This application discloses an all-weather intelligent desalination device, including a housing 300, a high-transparency top cover 100 installed on top of it, and multiple supports 600 installed at the bottom of the housing 300. The housing 300 is open, and the high-transparency top cover 100 and the housing 300 form a sealed space. The transparency of the high-transparency top cover 100 can minimize the reflectivity of sunlight and ensure that as much sunlight as possible enters the housing 300 so that the solar thermal device 400 can fully absorb the heat of solar energy.

[0050] Specifically, the high-transparency top cover 100 is sealed to the housing 300. The high-transparency top cover 100 includes a first inclined plate 110, a second inclined plate 120, and two parallel side plates 130. The connection between the first inclined plate 110 and the second inclined plate 120 is located above the first chamber 10.

[0051] The housing 300 includes a first chamber 10 for containing raw water and a second chamber 20 for collecting fresh water. There are two second chambers 20, which are respectively located on both sides of the first chamber 10, and the width of the second chamber 20 is smaller than the width of the first chamber 10.

[0052] The bottoms of the first inclined plate 110 and the second inclined plate 120 are respectively connected to the side walls of the two second chambers 20; the periphery of the side plate 130 is respectively connected to the first inclined plate 110, the second inclined plate 120, and the box body 300.

[0053] A solar energy storage device 200 is installed on the side of the housing 300 to absorb solar energy and convert thermal energy into electrical energy for storage.

[0054] The solar energy storage device 200 includes a solar panel, an energy storage component, and an electric heating component. The solar panel is installed on the side of the housing 300. The energy storage component is connected to the solar panel to store electrical energy and to supply electric heat to the electric heating component.

[0055] The electric heating component is located in the first chamber 10, specifically, 1 / 5 of it is exposed above the water surface and 4 / 5 is immersed in the water.

[0056] Preferably, the energy storage component is a battery.

[0057] The first chamber 10 is equipped with several photothermal devices 400. The several photothermal devices 400 are connected to the housing 300 through several rotating shaft devices, and the several photothermal devices 400 are set independently.

[0058] The rotating shaft device includes a first connecting shaft 510, a second connecting shaft 520, and a drive motor (not shown in the figure). The drive motor is mounted on the housing 300. One end of the first connecting shaft 510 is fixedly connected to the power output end of the drive motor, and the other end is fixedly connected to one end of the photothermal device 400. One end of the second connecting shaft 520 is fixedly connected to the other end of the photothermal device 400, and the other end is rotatably connected to the housing 300.

[0059] The photothermal device 400 includes a photothermal structure and a hydrophobic layer 410, a first hydrophilic layer 420, a second hydrophilic layer 430 and a third hydrophilic layer 440 disposed on the outside of the photothermal structure. The first hydrophilic layer 420 surrounds the periphery of the hydrophobic layer 410 to form a first planar structure.

[0060] The second hydrophilic layer 430 is disposed perpendicular to the first planar structure; the third hydrophilic layer 440 is connected to the second hydrophilic layer 430 and forms the second planar structure. That is, in this embodiment, the first hydrophilic layer 420, the second hydrophilic layer 430 and the third hydrophilic layer 440 form a covering arrangement for the hydrophobic layer 410.

[0061] A raw water storage chamber is formed between several photothermal devices 400 and the bottom of the box 300 for storing a large amount of raw water; an evaporation and condensation chamber is formed between several photothermal devices 400 and the high-permeability top cover 100 for water vapor to float. Since the temperature of the high-permeability top cover 100 is much lower than the temperature of water vapor, it will condense into fresh water droplets on the inner wall of the high-permeability top cover 100. After a certain amount of accumulation on the inner wall, it will flow along the inclined surface under the action of gravity to the top of the second chamber 20 and fall into the second chamber 20 for storage.

[0062] During the day, sunlight shines through the high-transparency top cover 100 onto the photothermal structure, generating heat through the photothermal effect and concentrating the heat at the evaporation interface to efficiently produce water vapor. The water vapor then condenses into distilled water on the high-transparency top cover 100 and slides down the cover to the second chambers 20 on both sides for storage. At the same time, the solar panels also generate waste heat when exposed to sunlight, which can be recycled to heat the raw water in the first chamber and promote evaporation.

[0063] When there is sufficient sunlight during the day, the main limitation on water evaporation is the water transport rate. At this time, the second planar structure of the photothermal device 400 is oriented downwards by the rotating shaft device, that is, the hydrophobic layer 410 is oriented upwards. Through the connection of the third hydrophilic layer 440, the second hydrophilic layer 430 and the first hydrophilic layer 420, a faster and stronger water absorption effect is formed, that is, the rapid supply and transport of water is achieved, and the water vapor evaporation efficiency is improved.

[0064] During periods of insufficient sunlight during the day, the main limitation on water evaporation is the insufficient heat generated by sunlight. At this time, by using the rotating shaft device to align the first planar structure of the photothermal device 400 downwards, i.e., the hydrophobic layer 410 downwards, the heat can be concentrated to the greatest extent in the thinner water layer on the upper surface, which suppresses the heat conduction loss to the water body below and promotes water evaporation.

[0065] Alternatively, during periods of insufficient sunlight during the day, not only can the first planar structure of the photothermal device 400 be positioned downwards, i.e., the hydrophobic layer 410 is positioned downwards, but stored electrical energy can also be used to supply electric heat through an electric heating component to provide sufficient temperature for the photothermal structure, ensuring continuous and efficient water evaporation and greatly improving the desalination rate.

[0066] At night, the electrical energy stored in the energy storage component powers the electric heating component to transfer heat to the raw water, continuing the evaporation of the water and achieving desalination around the clock.

[0067] The second chamber 20 is also equipped with a ramp, and an outlet is provided on the side of the second chamber 20, so that fresh water can be deposited on one side of the second chamber 20 and easily discharged from the outlet.

[0068] Preferably, the longitudinal axis of the first connecting shaft 510 and the longitudinal axis of the second connecting shaft 520 are aligned with the longitudinal center axis of the photothermal device 400 to improve the stability of the flipping.

[0069] In this embodiment, the longitudinal central axis of the photothermal device 400 is perpendicular to the longitudinal axis of the housing 300; three photothermal devices 400 are provided, and the three photothermal devices 400 are arranged in parallel and at equal intervals.

[0070] Three photothermal devices 400 form a photothermal conversion layer covering the first chamber 10. At the same time, the sum of the widths of the three photothermal devices 400 is less than the length of the first chamber 10, ensuring that the flipping of the three photothermal devices 400 does not interfere with each other.

[0071] Preferably, multiple supports 600 are evenly arranged to ensure stable support for the housing 300.

[0072] Furthermore, the all-weather intelligent desalination device also includes a central control center and a light intensity detection device. The light intensity detection device and the rotating shaft device are both connected to the central control center via signals. The light intensity detection device is used to detect the intensity of sunlight in real time.

[0073] During operation, the central control center controls the rotating shaft device based on the first range of light intensity detected by the light intensity detection device to flip the first planar structure to the bottom; the central control center controls the rotating shaft device based on the second range of light intensity detected by the light intensity detection device to flip the first planar structure to the top, and the light intensity of the second range is greater than that of the first range.

[0074] In low light conditions, the hydrophobic layer 410 of one or more photothermal devices 400 is automatically flipped downwards. To ensure high evaporation efficiency, a combination of photothermal and electrothermal methods is used. For electrothermal purposes, stored electrical energy is used to supply heat through an electric heating component, providing sufficient temperature for the photothermal structure and ensuring continuous and efficient water evaporation. In strong light conditions, the hydrophobic layer 410 is flipped upwards, and rapid water absorption is achieved through the large-area third hydrophilic layer 440 underneath, the surrounding second hydrophilic layer 430, and the enclosing first hydrophilic layer 420, ensuring a rapid supply of raw water and improving evaporation efficiency.

[0075] The all-weather intelligent desalination device disclosed in this application can efficiently produce fresh water during the day when there is sufficient sunlight by relying on interfacial evaporation technology and photothermal effect to evaporate and condense water. It can also charge the battery through the photovoltaic effect of the solar panel. At the same time, the solar panel will also generate waste heat when exposed to sunlight, which can be recycled to heat the water in the first chamber. During the night when there is insufficient sunlight and on cloudy or rainy days, it can continue to maintain water evaporation by relying on the electrical energy stored in the battery during the day and heating the water through the electrothermal effect of the electric heating component. It has all-weather water evaporation capability.

[0076] The device disclosed in this application is clean and environmentally friendly, has a simple structure, occupies a small area, and has high efficiency in photothermal conversion and water evaporation. It can maintain water evaporation under various weather conditions and achieve all-weather seawater desalination.

[0077] Reference Figure 4 In this embodiment, five photothermal devices 400 are provided, which are arranged in parallel and at equal intervals. The width of a single photothermal device 400 decreases as the number increases. The arrangement of multiple photothermal devices 400 allows for more precise rotation adjustment according to the light intensity, so as to ensure a continuously high evaporation efficiency.
