Description

Technical Field

[0001] The present application relates to the technical field of seawater desalination, and in particular to a self-floating seawater desalination device that carries an interface evaporation material. Background Art

[0002] With the rapid development of the global economy and industrialization, human demand for water resources continues to increase. At the same time, the shortage and uneven distribution of global freshwater resources restrict the development of many countries.

[0003] The total volume of seawater in the world is about 13.7 billion cubic kilometers, and it is widely distributed. Therefore, in order to effectively solve the problem of water shortage, seawater desalination is a more feasible research direction. At present, the field of seawater desalination includes electrodialysis, distillation, reverse osmosis and ammonium carbonate ion exchange, but the common desalination methods currently consume a lot of energy.

[0004] Thermal interface evaporation desalination is a novel desalination technology that concentrates solar thermal energy at the evaporation interface. Its highly efficient energy conversion allows solar thermal energy to be concentrated efficiently at the gas-liquid interface, reducing heat loss and improving energy conversion efficiency. Furthermore, the interface evaporation material occupies a small footprint, making it easy to deploy and transport. It is suitable for use in remote areas or on isolated islands, where access to traditional energy systems is difficult. Furthermore, it offers a low cost, consumes no conventional energy, and produces no pollutants, making it an environmentally friendly solution. Therefore, it is considered a promising alternative to traditional evaporation technology, promoting its application and development in a wider range of fields.

[0005] However, existing interfacial evaporation technologies are mostly for land desalination, which requires pumping seawater into the desalination device and uses a single-sided inclined plate light-receiving structure with a fixed light-receiving angle, resulting in low evaporation efficiency.

[0006] Therefore, the present application provides a self-floating seawater desalination device carrying an interface evaporation material to solve the above-mentioned problems. Utility Model Content

[0007] The present application provides a self-floating seawater desalination device that carries an interface evaporation material, aiming to solve the problems raised in the background art, such as that the existing interface evaporation technology is mostly land-based desalination, seawater needs to be pumped into the desalination device, a single-sided inclined plate light-receiving structure is used, the light-receiving angle is fixed, and the evaporation efficiency is low.

[0008] To achieve the above objectives, the present application provides the following technical solution: a self-floating seawater desalination device carrying an interface evaporation material, comprising a floating mechanism, a carrying mechanism fixedly mounted on the floating mechanism for carrying the evaporation material, and a condensation mechanism fixedly mounted on the floating mechanism for receiving distilled water:

[0009] The floating mechanism includes a floating member that is annular and hollow inside, an evaporation chamber is defined on the floating member, an annular baffle is fixedly mounted on the floating member and is arranged concentrically with the floating member, an annular outer frame is fixedly mounted on the edge of the outer wall of the floating member and is arranged concentrically with the baffle, a water collection trough for collecting evaporated water is defined between the baffle and the outer frame, and a drain outlet is fixedly mounted on the outer frame and is connected to the water collection trough;

[0010] The carrying mechanism includes a connecting ring adapted to the evaporation chamber and threadedly connected to the floating member, the connecting ring is fixedly mounted with an interface evaporation material carrying platform, and the interface evaporation material carrying platform is provided with a seawater inlet connected to the evaporation chamber;

[0011] The condensation mechanism includes a transparent, hemispherical dome-shaped condenser bonded to an outer frame. A plurality of heat-conducting pipes are bonded to the condenser, evenly spaced around the circumference. To desalinate seawater, the interface evaporation material is mounted on a carrier platform. The carrier platform is then screwed to the bottom opening of the evaporation chamber on a floating member via a connecting ring. The floating member is then placed on the water surface. Seawater enters the evaporation chamber through the seawater inlet. Buoyancy forces the floating member to keep the device afloat. Sunlight is focused through the condenser onto the interface evaporation material, heating the seawater in the evaporation chamber. The heated seawater generates water vapor that rises until it contacts the inner surface of the condenser. The heat-conducting pipes cool the condenser surface, condensing the water vapor and flowing along the spherical surface of the condenser to a water collection tank. Distilled water is then removed through a drain pipe connected to the outlet. The device does not need to be installed on land, but directly contacts seawater for water. Furthermore, the hemispherical dome-shaped condenser receives light from a wider angle, thereby improving evaporation efficiency.

[0012] Preferably, in order to fix the condenser, the outer frame is provided with a supporting groove adapted to the outer wall of the condenser, and the condenser is snapped into the supporting groove to receive the evaporated water vapor and achieve a good sealing effect.

[0013] Preferably, in order to filter impurities, a filter tube is screwed into the seawater inlet and extends into the seawater. The filter tube is evenly provided with a plurality of circumferentially distributed filter grooves to reduce the impact on the internal interface evaporation material and improve evaporation efficiency.

[0014] Preferably, in order to focus the light beam, the focusing shield is a convex lens structure with a cross-sectional thickness gradually increasing from the edge to the center, thereby improving the heating efficiency and completing the evaporation of seawater more quickly.

[0015] Preferably, in order to fix the heat pipe, one end of the heat pipe is attached to the concentrator and the other end extends into the seawater, and a hoop is provided on the outer wall of the floating member to engage with the heat pipe, thereby quickly and efficiently cooling the water vapor on the inner wall of the concentrator.

[0016] The desalination device installs an interface evaporation material on an interface evaporation material carrying platform, then screws the interface evaporation material carrying platform to the bottom cavity opening of an evaporation chamber on a floating member through a connecting ring, then places the floating member on the water surface, and seawater enters the evaporation chamber through a seawater inlet. The floating member floats the device on the water surface due to buoyancy, and sunlight is concentrated and irradiated on the interface evaporation material through a focusing shield, heating the seawater in the evaporation chamber. The heated seawater generates water vapor which floats up until it contacts the inner surface of the focusing shield, and a heat conducting pipe cools the surface of the focusing shield. The water vapor is condensed due to the cooling and flows along the spherical surface of the focusing shield to a water collecting tank, and distilled water is led away through a water extraction pipe connected to an external drain outlet. The device does not need to be set up on land and directly contacts the seawater for water use, and the hemispherical dome-shaped focusing shield can receive light at a wider angle, thereby improving evaporation efficiency.

[0017] The float of the desalination device utilizes its own sealing property to float on the water surface, and has a longer service life compared with foam-type floats. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] Example 1

[0026] This embodiment provides a self-floating seawater desalination device carrying interface evaporation materials, such as Figure 1-4 As shown, the desalination device includes a floating mechanism 1, a supporting mechanism 2 fixedly mounted on the floating mechanism 1 for supporting evaporation materials, and a condensing mechanism 3 fixedly mounted on the floating mechanism 1 for receiving distilled water:

[0027] The floating mechanism 1 includes a floating member 11 that is annular and hollow inside, an evaporation chamber 12 being defined on the floating member 11, a baffle 13 that is annular and concentric with the floating member 11 being fixedly mounted on the floating member 11, an outer frame 14 that is annular and concentric with the baffle 13 being fixedly mounted on the outer edge of the floating member 11, a water collection trough 15 for collecting evaporated water being defined between the baffle 13 and the outer frame 14, and a drain outlet 16 that is connected to the water collection trough 15 being fixedly mounted on the outer frame 14;

[0028] The supporting mechanism 2 includes a connecting ring 21 adapted to the evaporation chamber 12 and threadedly connected to the floating member 11. An interface evaporation material supporting platform 22 is fixedly mounted on the connecting ring 21. The interface evaporation material supporting platform 22 is provided with a seawater inlet 23 connected to the evaporation chamber 12.

[0029] The condensing mechanism 3 includes a hemispherical dome-shaped and transparent condenser 31 bonded to the outer frame 14 , and a plurality of heat-conducting pipes 32 uniformly arranged in a circumferential direction are bonded to the condenser 31 .

[0030] During use, the interface evaporation material is installed on the interface evaporation material carrying platform 22, and then the interface evaporation material carrying platform 22 is screwed to the bottom cavity of the evaporation chamber 12 on the floating member 11 through the connecting ring 21. Then the floating member 11 is placed on the water surface, and seawater enters the evaporation chamber 12 through the seawater inlet 23. The floating member 11 floats the device on the water surface by buoyancy, and sunlight is concentrated and irradiated on the interface evaporation material through the focusing cover 31, heating the seawater in the evaporation chamber 12. The seawater is heated to generate water vapor that floats until it contacts the inner surface of the focusing cover 31. The heat pipe 32 cools the surface of the focusing cover 31, and the water vapor is condensed by cooling and flows along the spherical surface of the focusing cover 31 to the water collection tank 15. The distilled water is led away through the external water extraction pipe of the drain outlet 16. The device does not need to be set up on land, and water is directly in contact with seawater. In addition, the hemispherical dome-shaped focusing cover 31 receives light at a wider angle, thereby improving the evaporation efficiency.

[0031] It should be noted that the interface evaporation material includes one or more of carbon black, carbon nanotubes, graphene, and graphene oxide, and the focus cover 31 uses high light-transmittance materials including one or more of glass and polyethylene sheet.

[0032] Specifically, the outer frame 14 is provided with a support groove 17 that matches the outer wall of the condenser 31. The condenser 31 is snapped into the support groove 17. During use, adhesive is evenly applied to the support groove 17, and then the condenser 31 is turned upside down in the support groove 17 to complete the fixation with the outer frame 14, thereby sealing the evaporation chamber 12 meters and receiving the evaporated water vapor, with a good sealing effect.

[0033] More specifically, a filter tube 24 is threadedly connected to the seawater inlet 23, extending into the seawater. Several circumferentially distributed filter grooves 25 are evenly distributed on the filter tube 24. During use, before the float 11 is placed in the seawater, the filter tube 24 is threadedly connected to the seawater inlet 23. After the float 11 is placed on the seawater surface, the filter tube 24 is extended into the seawater. Seawater enters the seawater inlet 23 through the filter grooves 25, filtering out large floating particles or plankton in the seawater, reducing the impact on the internal interface evaporation material and improving evaporation efficiency.

[0034] Furthermore, the concentrator 31 is a convex lens structure with a cross-sectional thickness gradually increasing from the edge to the center. When in use, after sunlight shines on the concentrator 31, the concentrator 31 uses the convex lens to concentrate the light beam on the interface evaporation material, improving the heating efficiency and thus completing the evaporation of seawater more quickly.

[0035] Furthermore, one end of the heat pipe 32 is attached to the concentrator 31, while the other end extends into the seawater. A collar 33 is mounted on the outer wall of the floating member 11, which engages with the heat pipe 32. During operation, after the heat pipes 32 are arranged one by one, the collar 33 is placed over the heat pipe 32 and fixed to the outer wall of the floating member 11. This conducts heat from the surface of the concentrator 31 into the cooler seawater for thermal conduction and cooling, effectively and efficiently cooling the water vapor on the inner wall of the concentrator 31.

[0036] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
