Description

Technical Field

[0001] The invention relates to the technical field of seawater desalination, in particular to a self-supporting floating seawater desalination device. Background Art

[0002] Existing desalination plants, such as marine desalination plants, can produce several to tens of tons of fresh water for ocean-going ships every day through reverse osmosis membrane technology, with a desalination rate of up to 99.8%. These devices support customized design, are basically not affected by time, space and climatic conditions, and can continuously and stably produce freshwater resources with reliable quality. However, traditional technologies still have some bottlenecks, such as low photothermal conversion efficiency, insufficient desalination efficiency, and limited salt treatment capacity. Although new technologies such as reverse osmosis have optimized this field to a certain extent, there are still problems such as large equipment investment, high operating and maintenance costs, and the quality of fresh water is greatly affected by the quality of original seawater.

It has the advantages of transferring heat to the capillary material layer through the microporous tube to evaporate the seawater, and backwashing through the microporous tube; but this device requires multiple independent devices to work together, and the structure is complex, which increases the complexity of the device and the difficulty of operation. Summary of the invention

[0004] In order to overcome the above-mentioned defects in the prior art, a self-supporting floating seawater desalination device is provided.

[0005] The technical solution of the present invention is as follows: a self-supporting floating seawater desalination device, comprising an evaporator, a water storage assembly, a floating device and a water supply device; the evaporator is installed above the water storage assembly, and is used to receive and evaporate seawater stored in the water supply device; the water supply device is installed below the water storage assembly; the water storage assembly is installed between the water supply device and the evaporator, and is used to store fresh water; the floating device is installed on the outside of the water storage assembly.

[0006] Preferably, the evaporator comprises a first connecting ring, an arc-shaped cover and an evaporation material. The first connecting ring is assembled at the bottom of the arc-shaped cover for connecting the water storage assembly; the evaporation material is used to extract seawater stored in the water supply device into the evaporator.

[0007] Preferably, the water supply device includes a water supply base plate, a water supply shell and a water supply structure. The water supply structure is assembled in the water supply shell. The water supply base plate is used to support the water supply shell and the water supply structure.

[0008] Preferably, the water storage assembly comprises a second connecting ring and a water storage shell, the second connecting ring is assembled between the water supply shell and the water storage shell, and the water supply structure is connected to the evaporation material through the second connecting ring.

[0009] Preferably, a backflow prevention device is installed in the water storage assembly.

[0011] Preferably, the water storage housing and the water supply housing have the same diameter.

[0012] Preferably, an anti-backflow baffle is provided inside the anti-backflow member, and the anti-backflow member is a funnel-shaped structure, and the radius of the upper end of the funnel-shaped structure is greater than the radius of the lower end.

[0013] Preferably, the outer diameter of the fixing plate matches the inner diameter of the water storage shell.

[0014] Preferably, the floating devices are a plurality of hollow spheres evenly arranged on the side of the second connecting ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects: A self-supporting floating seawater desalination device realizes self-supporting floating and seawater desalination functions at sea through an evaporator, a water storage component, a floating device and a water supply device, and does not require an external fixing or supporting structure, thereby improving the flexibility and applicability of the device; the device has a simple structure and is easy to operate, and the water supply device can realize automatic water supply on the sea surface, thereby integrating automatic evaporation and automatic water storage functions, significantly improving the automation level and efficiency of the device; the anti-backflow device effectively reduces the loss of fresh water caused by factors such as strong winds or waves, and reduces resource waste.

[0016] Furthermore, the evaporator ensures that the evaporation material can stably receive and evaporate seawater from the water supply device through the combination of the first connecting ring and the arc cover. The arc cover allows the cooled fresh water to flow down along the arc cover, thereby improving the fresh water collection efficiency. The first connecting ring makes it easier to assemble the evaporator with other components.

[0017] Furthermore, the water supply device realizes the effective extraction and transportation of seawater through the combination of the water supply bottom plate, the water supply shell and the water supply structure. The water absorption holes arranged on the water supply bottom plate allow the seawater to smoothly enter the water supply structure, providing a continuous seawater supply for the evaporator.

[0018] Furthermore, the water storage assembly provides a safe storage space for desalinated fresh water through the assembly of the second connecting ring and the water storage shell. At the same time, the water supply structure is connected to the evaporation material through the second connecting ring, ensuring that fresh water can smoothly enter the water storage assembly from the evaporator. The second connecting ring is used to connect and install the water storage shell and the water supply shell, making the device installation more convenient.

[0019] Furthermore, a backflow prevention device is provided in the water storage assembly, and the backflow prevention device is used to prevent fresh water from flowing back into the evaporator, thereby improving the seawater desalination efficiency.

[0020] Furthermore, the backflow prevention device combines a fixed plate and a backflow prevention piece. The fixed plate improves the stability of the backflow prevention device, and the backflow prevention piece effectively prevents fresh water from re-entering the evaporator during storage, thereby preventing the fresh water from evaporating again and causing waste of resources.

[0021] Furthermore, the water storage shell and the water supply shell have the same diameter, making the water storage assembly and the water supply device more compact and coordinated in structure, improving the space utilization and aesthetics of the entire device, and allowing it to float on the sea without tipping over or capsizing.

[0022] Furthermore, the backflow prevention member with a funnel-shaped structure can more effectively prevent the backflow of fresh water. At the same time, its gradually shrinking funnel shape reduces the loss of fresh water caused by factors such as strong winds or waves, thereby reducing waste of resources; the backflow prevention baffle further prevents losses caused by the backflow of fresh water.

[0023] Furthermore, the fixing plate enables the backflow prevention device to be stably assembled in the water storage shell, thereby preventing fresh water from flowing back into the evaporator and reducing resource waste.

[0024] Furthermore, the hollow spherical floating device not only has good buoyancy, but also can effectively disperse the weight of the device, improving the stability and floating performance of the device. The uniform arrangement of multiple floating devices further enhances the balance and wind and wave resistance of the entire device. The device can be thrown directly into the water, ensuring its stability on the sea surface and being able to effectively cope with general wave impacts. Due to its self-supporting and self-floating characteristics, the need for manual maintenance is reduced, thereby achieving long-term stable continuous evaporation.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings: like Figures 1 to 3 As shown, a self-supporting floating seawater desalination device includes an evaporator 1, a water storage component 2, a floating device 3 and a water supply device 4; the evaporator 1 is used to receive and evaporate seawater from the water supply device; the water storage component 2 is used to store fresh water obtained by condensation after evaporation; the floating device 3 ensures that the entire device can float on the sea surface; the water supply device 4 is used to store and provide seawater to the evaporator.

[0031] The evaporator 1 is mounted above the water storage assembly 2, and is used to receive and evaporate seawater stored in the water supply device 4; the water supply device 4 is mounted below the water storage assembly 2; the water storage assembly 2 is mounted between the water supply device 4 and the evaporator 1, and is used to store fresh water; the floating device 3 is mounted on the outside of the water storage assembly 2; and an anti-backflow device 5 is mounted inside the water storage assembly 2.

[0032] The evaporator 1 includes a first connecting ring 11, an arc cover 12 and an evaporation material 13. The first connecting ring 11 is assembled at the bottom of the arc cover 12 and is used to connect the water storage assembly 2. The evaporation material 13 is used to extract the seawater stored in the water supply device 4 into the evaporator 1. The arc cover 12 is made of transparent material. In the sunlight, the evaporation material 13 quickly converts light into heat energy and transfers it to the seawater. The seawater evaporates, and the water vapor condenses at the top of the arc cover 12 and flows into the water storage assembly 2.

[0033] Bamboo shoots were used as raw materials, and high-temperature carbonization and freeze-drying were used to prepare bamboo shoot porous biochar and porous structures as photothermal materials and porous substrates, respectively. A preliminary evaporation material 13 was prepared by simple coating, and then a high-temperature pyrolysis reduction strategy was used to prepare silver nanoparticle-doped bamboo shoot porous carbon as a photothermal material. The final evaporation material 13 was prepared by coating and placed on the seawater surface. This material significantly improves the photothermal conversion efficiency due to its large heating area, making the evaporation efficiency reach 2.68kg / ㎡·h.

[0034] The water supply device 4 includes a water supply bottom plate 41, a water supply shell 42 and a water supply structure 43. The water supply structure 43 is assembled in the water supply shell 42. The water supply bottom plate 41 is used to support the water supply shell 42 and the water supply structure 43. The water supply bottom plate 41 is provided with a water absorption hole 411 for the water supply structure 43 to pass through.

[0035] The water supply structure 43 is a water-absorbing sponge. Through the water-absorbing hole 411, the water supply structure 43 is directly in contact with the seawater. The water supply structure 43 is connected to the evaporation material 13 to evaporate and desalinate the seawater. The water-absorbing sponge enables the seawater desalination device to realize automatic water supply on the sea surface, thereby integrating the automatic evaporation and automatic water storage functions. The automation degree and efficiency of the seawater desalination device are improved.

[0036] The water storage assembly 2 includes a second connecting ring 21 and a water storage shell 22 .

The backflow prevention member 52 is provided with a backflow prevention baffle, and the backflow prevention member 52 is a funnel-shaped structure, and the radius of the upper end of the funnel-shaped structure is greater than the radius of the lower end. It effectively prevents seawater from flowing back into the evaporator 1 under the action of gravity, ensuring the purity and effective use of fresh water. At least two backflow prevention members 52 are provided, so that fresh water can be collected faster, and fresh water can be prevented from flowing back into the inner cavity of the evaporator 1 above the fixed plate 51 to evaporate again, affecting the efficiency of seawater desalination.

[0038] Furthermore, the outer diameter of the fixing plate 51 matches the inner diameter of the water storage housing 22 to prevent fresh water from flowing directly onto the fixing plate 51 without passing through the backflow prevention member 52 , thereby making the water storage area of ​​the water storage assembly 2 more sealed.

[0039] The water storage shell 22 and the water supply shell 42 have the same diameter. The main material of the water storage shell 22 and the water supply shell 42 is acrylic glass material, which reduces heat loss and is tightly sealed. The water storage shell 22 and the water supply shell 42 are made of acrylic glass material. In order to reduce heat loss, they are connected by the second connecting ring 21 and are tightly sealed.

[0040] The floating device 3 is a hollow spherical device, and is provided in multiple pieces, which are evenly arranged on the side of the second connecting ring 21. The floating device 3 ensures the stability of the entire device on the sea surface and can effectively cope with general wave impacts.
