[0002] Seawater desalination is one of the important means to solve the problem of freshwater shortage, especially for coastal areas or arid areas. However, traditional seawater desalination devices have some shortcomings:

[0003] High energy consumption: Traditional desalination plants usually rely on large amounts of energy, such as coal or electricity, to drive the evaporation and condensation processes, which results in high energy consumption and expensive operating costs.

[0004] Low efficiency: The design of some traditional seawater desalination devices does not fully consider the efficiency optimization of evaporation and condensation, resulting in low fresh water recovery rate and low energy utilization efficiency.

[0005] Dependence on external energy: Many traditional desalination devices require external energy supply. If they are located in remote areas or lack electricity supply, the operation of the device will face difficulties. Utility Model Content

[0042] See also Figure 1-3 A low-energy desalination device comprises a main body, which is a treatment tank 1, and the upper part of which is designed to be conical to optimize the collection and condensation of steam.

[0043] A light-transmitting glass 2 is installed on the conical upper half of the treatment tank 1. The glass not only allows sunlight to penetrate to promote evaporation, but is also designed to be parallel to the outer surface of the evaporation guide cover 42, which can ensure that sunlight can irradiate the evaporation guide cover 42 to the greatest extent, thereby increasing the evaporation area, prompting condensed water droplets to slide down the glass surface, preventing re-evaporation, and optimizing fresh water recovery.

[0044] Evaporation mechanism:

[0045] A seawater storage pool 3 is provided in the processing tank 1 , and the bottom is supported by a support 31 so that it is separated from the bottom of the processing tank 1 , ensuring that subsequent fresh water can be directed to the fresh water discharge valve pipe 12 .

[0046] An evaporation mechanism 4 is installed in the seawater storage pool 3, including a first liquid pump 41 located at the center of the pool bottom and a liquid outlet pipe 43 at the top, the top end of the liquid outlet pipe 43 is connected to the evaporation guide cover 42, serving as a supporting structure of the evaporation guide cover 42. The evaporation guide cover 42 is conical, and the top end of the liquid outlet pipe 43 is connected to the top of the evaporation guide cover 42, and the seawater can flow evenly on the evaporation guide cover 42. This design can maximize the evaporation area, and the surface color of the evaporation guide cover 42 is set to pure black, which further improves the heat absorption evaporation efficiency.

[0047] Energy configuration:

[0048] A solar panel 6 is installed on the top edge of the lower half of the treatment tank 1 to directly convert solar energy into electrical energy to provide power for the operation of the evaporation mechanism 4. This energy self-sufficient design allows the device to operate independently in remote areas lacking external power supply, reducing operating costs and environmental impact.

[0049] Seawater supply system:

[0050] Seawater is replenished through the seawater introduction mechanism 5 located on the right side of the treatment tank 1. The second liquid pump 52 draws seawater from a nearby seawater source, introduces it through the outside of the liquid pumping pipe 53, and sends it into the seawater storage tank 3 through the liquid inlet pipe 51. The system design takes into account the need for continuous operation to ensure a stable supply of seawater.

[0051] Freshwater Collection and Discharge:

[0052] After the fresh water condenses in the cone-shaped upper part, it flows to the bottom along the inner wall of the tank by gravity and is discharged through the fresh water discharge valve pipe 12 located in the center. This discharge system is designed to be easy to maintain and prevent clogging, ensuring smooth collection and output of fresh water.

[0053] Device support structure:

[0054] A support 11 is provided at the bottom of the outer side of the processing tank so that the entire device is stably supported on the ground.

[0055] How it works

[0056] Seawater introduction:

[0057] The seawater is pumped into the system through the seawater introduction mechanism 5 located on one side of the device. The second liquid pump 52 extracts seawater from a nearby sea source, and sends it into the liquid inlet pipe 51 through the liquid pumping pipe 53, and then enters the seawater storage tank 3.

[0058] Seawater evaporation:

[0059] The seawater is pumped out from the storage tank 3 by the first liquid pump 41 and sent to the evaporation guide cover 42. Here, the seawater is distributed through the top of the evaporation guide cover 42 and is guided from its top surface to the inside of the seawater storage tank 3. During this period, the light-transmitting glass 2 guides the external sunlight to the surface of the evaporation guide cover 42, thereby irradiating the seawater on the evaporation guide cover 42 to promote its evaporation.

[0060] Steam condensation:

[0061] The evaporated water vapor rises to the upper conical area of ​​the treatment tank 1. Due to the conical design, the downward transfer of heat from the steam during the condensation process is minimized, improving the condensation efficiency. The water droplets condense on the inner side of the light-transmitting glass to form fresh water.

[0062] Freshwater Collection and Discharge:

[0063] The condensed fresh water flows along the inner wall of the treatment tank 1 to the bottom, is collected through the fresh water discharge valve pipe 12 at the center of the bottom, and is discharged to an external water storage facility.

[0064] Energy Management:

[0065] During the whole process, the solar panel 6 captures sunlight and converts it into electrical energy, which supplies the power required by the liquid pump and other electrical equipment, ensuring the self-sufficiency and high efficiency of the system operation.
