Description

Technical Field

[0001] This utility model relates to the field of seawater desalination technology, and in particular to a seawater desalination tower with air-cooled condensation and salt carving. Background Technology

[0002] Among various desalination technologies, distillation is widely used due to its strong adaptability to high-salinity seawater and high-quality produced water. Combining the desalination process with the resource utilization of by-products (such as sea salt), for example, to prepare raw materials for salt sculpture art, is an important development direction for improving the economic and environmental benefits of this technology.

[0003] Currently, some small, simple seawater desalination devices on the market, especially those based on the evaporation-condensation principle, typically have relatively simple structures. These devices mainly consist of an evaporation chamber for containing and heating seawater and a condensation surface. Their working principle is as follows: the seawater in the evaporation chamber is heated by solar radiation or simple electric heating to produce water vapor; the water vapor rises and contacts the relatively cooler inner wall or top cover of the device (i.e., the condensation surface); the water vapor releases heat and condenses on the condensation surface, forming freshwater droplets that, under gravity, collect along the inclined surface into a collection tank and are finally discharged.

[0004] However, the aforementioned simple distillation apparatus relying on natural cooling suffers from a fundamental efficiency bottleneck: its extremely low condensation rate. The core problem lies in the fact that the condensation process depends entirely on passive, natural heat exchange between the condensing surface and the surrounding air. This heat dissipation method is inefficient, resulting in the condensing surface temperature not being rapidly reduced, maintaining a small temperature difference with the internal water vapor. According to the principles of heat transfer, a small temperature difference translates to an extremely slow condensation rate. Especially under conditions of high ambient temperature or windless weather, the heat dissipation effect worsens further, directly causing a large amount of water vapor to escape from the exhaust port before it has fully condensed, resulting in low water production and significant energy waste, making it difficult to meet the practically applicable water production requirements. Therefore, a wind-cooled condensation salt-carved seawater desalination tower is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this invention provides a wind-cooled condensation salt-carved seawater desalination tower, aiming to improve the problems of simple distillation devices that rely on passive natural cooling, resulting in low heat dissipation efficiency, small temperature difference between the condensing surface and water vapor, and slow condensation rate. This causes a large amount of steam to escape without condensation, resulting in low water production and serious energy waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind-cooled condensation salt-carved seawater desalination tower, comprising a tower body, a heating wire fixedly connected to the lower side of the tower body, a stirring mechanism installed on the upper surface of the tower body, multiple connecting blocks fixedly connected to the upper side of the inner wall of the tower body, a conical hopper fixedly connected to one side of the outer wall of the multiple connecting blocks, an L-shaped annular channel fixedly connected to the lower side of the inner wall of the tower body near the connecting blocks, a transmission pipe fixedly connected to the outer wall of the tower body, and a condensation mechanism installed at one end of the transmission pipe; The condensation mechanism includes a cooling box, which is fixedly connected to one end of a transmission pipe. A partition is fixedly connected to the side wall of the cooling box. A cooling plate is fixedly connected to one side of the outer wall of the partition. Multiple cooling rods are fixedly connected to the other side of the outer wall of the partition. A protective cover is fixedly connected to one side of the outer wall of the cooling box. A connecting plate is fixedly connected inside the protective cover. A fan is fixedly connected inside the connecting plate. A dust cover is provided on the outer wall of the fan.

[0007] As a further description of the above technical solution: The stirring mechanism includes a motor, the lower surface of which is fixedly connected to the upper surface of the tower body. The output end of the motor is fixedly connected to a transmission shaft that penetrates the interior of the tower body. A stirring blade is fixedly connected to the outer wall of the transmission shaft, and an L-shaped scraper is fixedly connected to the lower end of the transmission shaft.

[0008] As a further description of the above technical solution: A condensate scraper is fixedly connected to the outer wall of the transmission shaft, and a scraper strip is fixedly connected to the lower surface of the condensate scraper.

[0009] As a further description of the above technical solution: The outer wall of the condensate scraper is fixedly connected with a symmetrical guide channel one, and the outer wall of the scraper is fixedly connected with a symmetrical guide channel two.

[0010] As a further description of the above technical solution: The lower surface of the condensate scraper is slidably connected to the upper surface of the conical hopper, and the upper surface of the scraper bar is slidably connected to the lower surface of the conical hopper.

[0011] As a further description of the above technical solution: A discharge pipe is fixedly connected to the lower side of the outer wall of the tower body, and an air outlet pipe is fixedly connected to the upper surface of the tower body.

[0012] As a further description of the above technical solution: The protective cover is installed on the outside of the cooling rod, and a water outlet pipe is fixedly connected to one side of the outer wall of the cooling box.

[0013] As a further description of the above technical solution: The conical bucket, guide channel one, and guide channel two are all located on the upper side of the L-shaped annular channel, and one end of the transmission pipe is connected to one side of the L-shaped annular channel.

[0014] This utility model has the following beneficial effects: 1. In this utility model, seawater is continuously heated by heating wires, causing steam to condense on the inner wall of the tower and collect in the upper conical bucket. The condensate is then transported to the inner side of the L-shaped annular channel through the conical bucket, and then transported to the inside of the cooling box through the transmission pipe. At the same time, the external condensation mechanism uses large-surface-area cooling plates and cooling rods, and is forced by a fan for air cooling, which greatly enhances the heat dissipation effect and improves the condensation rate.

[0015] 2. In this invention, the motor-driven stirring mechanism not only ensures uniform heating of seawater through the stirring blades, but its L-shaped scraper at the bottom, rotating with the transmission shaft, continuously scrapes and organizes the salt that precipitates and deposits at the bottom of the tower due to water evaporation. This prevents the salt from forming hard scale in the heating area, ensuring long-term heat exchange efficiency. Simultaneously, it continuously gathers loose salt crystals. The linked condensate scraper and scraper blades rotate synchronously with the transmission shaft, continuously scraping the surface of the conical hopper. Through precise flow guidance in the guide channel, the scraped freshwater is forcibly collected into the L-shaped annular channel and discharged through the transmission pipe, thereby improving the practicality of the device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 - Figure 5 This utility model provides an embodiment of a seawater desalination tower with air-cooled condensation salt carving, comprising a tower body 1 as the main frame and reaction vessel, a heating wire 2 as a heat source fixedly connected to the lower inner side of the tower body 1, which provides continuous and stable heat energy for seawater evaporation, a stirring mechanism for stirring the internal liquid and processing by-products installed on the upper surface of the tower body 1, a plurality of connecting blocks 8 for structural support fixedly connected to the upper inner wall of the tower body 1, a conical hopper 7 for preliminary collection of condensate fixedly connected to one side of the outer wall of the plurality of connecting blocks 8, an L-shaped annular channel 9 for collecting and guiding condensate fixedly connected to the lower inner wall of the tower body 1 near the connecting blocks 8, and a transmission pipe 10 for exporting the collected freshwater fixedly connected to the outer wall of the tower body 1, with a condensation mechanism for rapidly cooling the freshwater installed at one end of the transmission pipe 10; The condensation mechanism includes a cooling box 11 as the main cooling unit. The interior of the cooling box 11 is fixedly connected to one end of the transmission pipe 10 to receive fresh water. A partition 12 for fixing the internal structure is fixedly connected to the side wall of the cooling box 11. A large-area cooling plate 13 is fixedly connected to one side of the outer wall of the partition 12, while multiple cooling rods 14 for significantly increasing the heat dissipation surface area are fixedly connected to the other side of the outer wall of the partition 12. A protective cover 15 for safety protection and airflow guidance is fixedly connected to one side of the outer wall of the cooling box 11. A connecting plate 16 for installing a fan 17 is fixedly connected inside the protective cover 15. A fan 17 for providing forced convection air for efficient heat dissipation is fixedly connected inside the connecting plate 16. A dust cover 18 for preventing the inhalation of debris is provided on the outer wall of the fan 17. The stirring mechanism includes a motor 3 as a power source. The lower surface of the motor 3 is fixedly connected to the upper surface of the tower body 1. The output end of the motor 3 extends into the interior of the tower body 1 and is fixedly connected to a transmission shaft 4 for transmitting power. The outer wall of the transmission shaft 4 is fixedly connected to a stirring blade 5 for stirring the seawater to make it heat evenly. The lower end of the transmission shaft 4 is fixedly connected to an L-shaped scraper 6 for scraping and collecting the precipitated salt.

[0020] Specifically, during operation, motor 3 drives transmission shaft 4 to rotate, and the stirring blades 5 on it continuously agitate the seawater heated by heating wire 2 to accelerate and equalize heat transfer, thereby improving evaporation efficiency. Simultaneously, water vapor condenses inside the tower and is collected by conical hopper 7 and L-shaped annular channel 9, and then sent to an external high-efficiency condensation mechanism via transmission pipe 10. This mechanism uses fan 17 to force-cool the large-surface-area cooling plates 13 and cooling rods 14, greatly improving the condensation rate and freshwater production efficiency. Furthermore, the L-shaped scraper 6 at the lower end of transmission shaft 4 simultaneously scrapes and organizes the salt deposited after evaporation, effectively preventing scale formation, ensuring long-term heating efficiency, and enabling the resource utilization of by-product salt directly as raw material for salt carving.

[0021] Reference Figure 1 - Figure 5 A condensate scraper 21 for scraping condensate is fixedly connected to the outer wall of the transmission shaft 4. A scraper strip 23 for auxiliary scraping is fixedly connected to the lower surface of the condensate scraper 21. A guide channel 22 for guiding condensate is fixedly connected to the outer wall of the condensate scraper 21, which is symmetrically arranged on the left and right. A guide channel 24 is also fixedly connected to the outer wall of the scraper strip 23, which is symmetrically arranged on the left and right. To achieve the scraping action, the lower surface of the condensate scraper 21 is slidably connected to the upper surface of the conical hopper 7, while the upper surface of the scraper strip 23 is slidably connected to the lower surface of the conical hopper 7. The lower surface of the outer wall of the tower body 1 is... A discharge pipe 20 for discharging solid salts is fixedly connected to the side, and an outlet pipe 25 for discharging non-condensable gases is fixedly connected to the upper surface of the tower body 1; a protective cover 15 is installed on the outside of the cooling rod 14 to provide protection, and a water outlet pipe 19 for discharging finished fresh water is fixedly connected to one side of the outer wall of the cooling box 11; in terms of structural layout, the lower sides of the conical bucket 7, the first guide channel 22 and the second guide channel 24 are all set on the upper side of the L-shaped annular channel 9 to achieve gravity water collection, and one end of the transmission pipe 10 is connected to one side of the L-shaped annular channel 9 to form a complete liquid transmission path.

[0022] Specifically, as the transmission shaft 4 rotates, the condensate scraper 21 and scraper strip 23 fixed on it rotate synchronously, continuously scraping the inner and outer surfaces of the conical bucket 7, forcibly stripping away the condensate adhering to the surface. The scraped-off fresh water then flows accurately into the L-shaped annular channel 9 below, guided by guide channel one 22 and guide channel two 24. This active, forced collection method completely solves the problem of secondary evaporation caused by condensate retention due to surface tension or dripping into the regenerating brine, significantly improving the efficiency of net water production. Finally, the collected fresh water is discharged through the water outlet pipe 19, the precipitated salt is discharged through the discharge pipe 20, and the non-condensable gas is discharged through the gas outlet pipe 25, forming a complete material separation and collection path, greatly enhancing the practicality and output performance of the device.

[0023] Working principle: When the device is needed, the seawater to be treated is first injected into the tower body 1 through the inlet on the lower side of the transmission pipe 10. After the device is started, the control system connects the heating wire 2 located on the lower side of the tower body 1 to start heating the seawater. At the same time, the motor 3 installed on the upper surface of the tower body 1 is started, and the transmission shaft 4 is driven to rotate stably through its output end. The transmission shaft 4 drives the stirring blades 5 fixed on its outer wall to continuously and evenly stir the seawater in the tower body 1. This not only prevents local overheating and improves heat transfer efficiency, but also accelerates the evaporation process of the seawater, thereby generating a large amount of water vapor in the tower space. Secondly, the generated water vapor rises inside the tower body 1. When it comes into contact with the relatively cool surface of the conical bucket 7 fixed on the upper side of the inner wall of the tower body 1, condensation occurs, releasing heat and liquefying to form fresh water droplets. At the same time, with the synchronous rotation of the transmission shaft 4, the condensate scraper 21 fixed on its outer wall and the scraper 23 fixed on its lower surface will continuously and synchronously slide and scrape the upper and lower surfaces of the conical bucket 7. The condensed fresh water that is scraped down is collected and introduced into the L-shaped annular channel 9 below under the guiding action of the left and right symmetrical guide channel 1 22 and guide channel 2 24. Secondly, the fresh water collected in the L-shaped annular channel 9 is transported to the cooling box 11 through the transmission pipe 10 connected to it. At the same time, in the condensation mechanism, the fan 17 installed inside the protective cover 15 runs at high speed, generating a strong airflow to force-cool the large heat dissipation area cooling plate 13 and multiple cooling rods 14. Through efficient convection heat exchange, the heat of the system is quickly removed. Firstly, the fresh water is fully cooled in the cooling box 11 and discharged from the water outlet pipe 19. Secondly, the temperature of the entire condensation system is reduced, thereby greatly improving the condensation rate inside the tower body 1. Finally, as seawater evaporates and freshwater is collected, the salt that precipitates due to the decrease in water content will be deposited at the bottom of the tower 1. During the rotation of the L-shaped scraper 6 fixed at the lower end of the transmission shaft 4, the deposited salt is continuously scraped, broken, and aggregated. This effectively prevents the salt from forming hard scale on the surface of the heating wire 2, which would affect the heat exchange efficiency. It also organizes the loose salt crystals into raw materials suitable for salt sculpture creation. Finally, the salt can be discharged through the discharge pipe 20 on the lower side, while the non-condensable gas is discharged through the gas outlet pipe 25 on the upper surface.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
