[0046] The utility model will be described in further detail below in connection with the drawings and embodiments. It is particularly pointed out that the following embodiments are only used for illustrating the utility model, but do not limit the scope of the utility model. Similarly, the following embodiments are only part of the embodiments of the utility model rather than all the embodiments, and all other embodiments obtained by the ordinary skilled in the art without making creative efforts belong to the scope of the utility model protection.

[0047] Please refer to Figures 1 to 5 The embodiment provides a seawater desalination collection device based on evaporation effect, which comprises a first box body 1, a liquid collecting assembly 2 and a guide assembly 3, the first box body 1 comprises a first containing cavity 11, a first air inlet and a first liquid outlet, the first containing cavity 11 is communicated with the first air inlet and the first liquid outlet, the first air inlet is used for inputting water vapor, and the first liquid outlet is used for outputting condensed water; the liquid collecting assembly 2 comprises a bottom plate and a plurality of liquid collecting cones, the plurality of liquid collecting cones are distributed on the bottom plate in a preset mode, the bottom plate is arranged on the inner side of the first containing cavity 11, and the liquid collecting cones are used for collecting water vapor and condensing the water vapor into water droplets; the guide assembly 3 comprises a first guide plate 31 and a second guide plate 32, the first guide plate 31 is arranged in the first containing cavity 11 in a first included angle, the second guide plate 32 is arranged in the first containing cavity 11 in a second included angle, and the first guide plate 31 and the second guide plate 32 are oppositely arranged below the liquid collecting assembly 2, the first guide plate 31 and the second guide plate 32 divide the first containing cavity 11 into a first upper cavity and a first lower cavity, the first upper cavity contains water vapor, the first lower cavity is used for containing condensed water of the water vapor, the first guide plate 31 has a first guide-out end, the second guide plate 32 has a second guide-out end, the first guide-out end and the second guide-out end are oppositely arranged to form a guide-out gap 35, and the guide-out gap 35 is used for guiding the condensed water droplets to flow from the first upper cavity into the first lower cavity.

[0048] In the embodiment, the first box body 1 is used for containing water vapor and water droplets condensed from the water vapor. The first containing cavity 11 is arranged in the first box body 1, the first air inlet is arranged at the upper portion of the first box body 1, the first liquid outlet is arranged at the bottom of the first box body 1, the first liquid outlet can guide the condensed fresh water in the first containing cavity 11, and the first air inlet is used for inputting water vapor.

[0049] The liquid collecting assembly 2 comprises a bottom plate and a liquid collecting cone in a conical structure. The material of the liquid collecting cone can be the same as that of the bottom plate, and the liquid collecting cone can be integrally formed with the bottom plate. The liquid collecting assembly 2 is arranged in the first accommodating cavity 11. It should be noted that the liquid collecting assembly 2 can be arranged above the first accommodating cavity 11 or on the side wall of the first accommodating cavity 11. According to the Laplace differential pressure, the pressure difference of liquid or gas on a curved surface is proportional to the curvature of the surface and the surface tension of the liquid or gas. Therefore, according to the Laplace differential pressure, when the curvature radius of the liquid drop or the bubble decreases, the pressure difference increases; and when the surface tension of the liquid drop or the bubble increases, the pressure difference also increases. This means that the liquid drop or the bubble will generate a larger pressure difference at a smaller curvature radius, thereby making it easier to break or merge. The liquid collecting cone utilizes this principle of Laplace differential pressure. A plurality of conical bodies are arranged on the inner wall of the first cabinet 1, which can accelerate the condensation efficiency of water vapor around the liquid collecting cone. This method is different from the existing principle of reducing temperature to condense water vapor. When the inner wall of the first cabinet 1 is covered with the liquid collecting cone, the condensation efficiency of water vapor will be significantly improved compared with the smooth side wall. At the same time, the conical structure can guide the water droplets after condensation, so that the water droplets condensed from water vapor condense into water droplets at the tip of the cone, as shown in Figure 4 .

[0050] In this embodiment, the guide assembly 3 comprises a first guide plate 31 and a second guide plate 32. The upper surfaces of the first guide plate 31 and the second guide plate 32 can be coated with a hydrophobic coating to facilitate the guidance of condensed water. In this embodiment, the first guide plate 31 is arranged in the first accommodating cavity 11 at a first inclination angle, and the second guide plate 32 is arranged in the first accommodating cavity 11 at a second inclination angle, as shown in Figure 1 . The first accommodating cavity 11 is divided into a first upper chamber and a first lower chamber. In the first upper chamber, water exists mainly in the form of water vapor, and in the first lower chamber, water exists in the form of liquid. The first guide plate 31 and the second guide plate 32 can form a V-shaped structure inclined towards the middle of the first cabinet 1, which facilitates the collection and guidance of the surrounding condensed water. At the same time, the arrangement of the first guide plate 31 and the second guide plate 32 can reduce the air space in the first lower chamber, further reducing the probability of secondary evaporation of liquid water.

[0051] This embodiment promotes scientific exploration in the field of seawater desalination by studying the combination of evaporation effect and conical array collection structure, providing a new perspective for understanding water vapor collection and droplet dynamics. The innovative liquid collection cone array structure design achieves efficient water vapor collection by utilizing Laplace pressure difference, which is a breakthrough in the field of seawater desalination. It not only improves the collection efficiency of water vapor, but also simplifies the system structure and reduces the cost, providing a new solution for the development of seawater desalination technology. This embodiment can be directly applied to coastal and island areas for freshwater supply, solving the problem of freshwater resource shortage caused by geographical location and climate conditions in these areas. In addition, its modular design makes the system highly flexible and expandable, which can be customized and adjusted according to different application scenarios and needs, such as sewage treatment, etc., improving the practicality and adaptability of the technology.

[0052] In some optional embodiments, the device can be obtained by the following steps:

[0053] (1) Theoretical simulation and optimization design: Based on the principle of Laplace pressure difference and fluid dynamics, the liquid collection assembly 2 and the first box 1 are optimized and designed through molecular dynamics simulation software LAMMPS and physical experiments, to determine the optimal cone angle, length and surface energy parameters, to realize the directional transport and efficient collection of water vapor.

[0054] (2) Material selection and preparation: According to the surface energy parameters of theoretical research, the contact angle of water droplets is obtained. According to the contact angle parameters, reasonable materials are selected. Finally, the liquid collection cone and the bottom plate are prepared through 3D printing and template method and other technologies.

[0055] (3) System integration and performance test: Select a solar light intensity, integrate the liquid collection assembly 2, the first box 1, the first box 1 described below and other components to build a complete seawater desalination collection system. The performance of the system is tested, including evaporation efficiency, desalination effect, power consumption and other indicators.

[0056] (4) Structure development and product manufacturing: According to the structure optimization size and physical experiment results, develop water collection membrane to realize industrialization.

[0057] The design steps of the seawater desalination system proposed by the above steps realize the revolutionary optimization of the seawater desalination process by integrating a unique liquid collection cone. Through accurate calculation and simulation, a series of conical collection plates are created, which are arranged at a specific angle and spacing to form an efficient vapor collection network. When seawater is heated and evaporated by solar energy or other heat sources, the liquid collection cone can use the Laplace pressure difference to make the small water vapor droplets on the collection plate gather into large droplets, and finally move downward and collect under the action of gravity. This process does not require additional external condensing systems, simplifying the system structure and reducing costs. The advantage of the self-driven mechanism of the collection device shown in the embodiment is that it can achieve efficient collection of water vapor without external energy input, greatly reducing the energy consumption of the system. At the same time, due to the removal of complex condensing equipment, the overall cost and maintenance difficulty of the system have been significantly reduced. The large surface area design of the liquid collection cone not only increases the contact probability of water vapor with the collection surface, but also improves the processing capacity of the system. Even in harsh environments with high temperature and strong sunlight, stable freshwater output can be maintained.
