[0002] It is a device that uses thermal energy to heat and evaporate seawater, and then condenses the steam to obtain fresh water. It is mainly used on ships to solve the problem of fresh water supply during ocean voyages, and removes salt and impurities from seawater through the distillation process.

[0003] In existing technologies, seawater is heated by heating elements. Seawater has an extremely complex composition, containing a large amount of salt and various impurities. During the evaporation of seawater, since the salt and impurities do not evaporate with the water vapor, they gradually deposit and adhere to the surface of the heating element. Over time, if these salt and impurities attached to the surface of the heating element are not cleaned in time, a thick layer of dirt will form on the surface of the heating element. This layer of dirt has poor thermal conductivity, which will greatly hinder the transfer of heat and seriously affect the heating performance of the heating element. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] Please see Figure 1 - Figure 5 This utility model provides an embodiment: a marine seawater purification device, including a treatment tank 1, a drain outlet 5 and a water inlet 6 installed on the side of the treatment tank 1, a sewage outlet 7 installed at the bottom of the treatment tank 1, a sealing cover 8 installed on the top of the treatment tank 1, a pressure relief valve 9 installed on the sealing cover 8, and a support leg 10 installed on the treatment tank 1. It also includes a mounting plate 21 installed on the treatment tank 1, a heating element 22 mounted on the mounting plate 21 for heating seawater, a scraper 23 slidably connected to the heating element 22, an adjustment assembly installed between the mounting plate 21 and the scraper 23, and a condensation assembly installed inside the treatment tank 1. The adjustment assembly drives the scraper 23 to slide and scrape away impurities from the surface of the heating element 22. The heating element 22 heats the seawater to evaporate, and the condensation assembly condenses the vapor into liquid. The seawater to be treated is added into the treatment tank 1 through the water inlet 6, and the heating element 22 heats the seawater to make it... Boiling water turns into steam and rises. Then, the steam is converted into liquid by the condenser and stored in the upper layer of the treatment tank 1. The upper layer is the gap between the partition plate 42 and the treatment tank 1. The liquid can then be discharged through the drain port 5. The drain port 5, the inlet port 6, and the drain port 7 are all equipped with flanges, which can be connected to pipes to transport and extract liquid into the treatment tank 1. Impurities at the bottom can be discharged through the drain port 7. The pressure relief valve 9 can relieve the pressure inside the treatment tank 1 to prevent excessive internal pressure. The scraper 23 can be driven to slide by the adjusting component to scrape off impurities on the surface of the heating element 22, preventing impurities from accumulating on the heating element 22 and ensuring the performance of the heating element 22. The heating element 22 can be an industrial-grade metal heater, made of thick-walled, high-hardness, corrosion-resistant alloys such as Hastelloy or Inconel, in a tubular shape.

[0022] Please see Figure 2 A further solution based on this embodiment is as follows: the treatment tank 1 has an installation groove at the corresponding position of the installation plate 21, and the heating element 22 passes through the installation groove and is installed on the installation groove through the installation plate 21, so that the installation plate 21 can be quickly installed and removed from the treatment tank 1, and the matching installation groove can make the installation of the installation plate 21 more precise, and a sealing ring is provided between the installation plate 21 and the treatment tank 1 to prevent seawater from flowing out from the gap of the installation groove.

[0023] Please see Figure 2 - Figure 3 A further solution based on this embodiment is as follows: three heating elements 22 are provided, and the three heating elements 22 are symmetrically arranged on the mounting plate 21, and the scraper 23 is slidably connected to the three heating elements 22. By the uniform distribution of the three heating elements 22, seawater can be heated quickly, thereby improving work efficiency.

[0024] Please see Figure 3 - Figure 4 A further solution based on this embodiment is as follows: The adjustment component includes a limiting cylinder 31 fixedly connected to the mounting plate 21, an external hexagonal rotating block 32 rotatably connected to the limiting cylinder 31, a threaded rod 33 fixedly connected to one end of the external hexagonal rotating block 32, and a threaded cylinder 34 threadedly connected to the threaded rod 33. The threaded cylinder 34 is slidably connected inside the limiting cylinder 31 and is fixedly connected to the scraper 23. By rotating the limiting cylinder 31, the threaded cylinder 34 can be pushed to slide through the threaded pair. The threaded cylinder 34 can drive the scraper 23 to avoid moving on the heating element 22. The scraper 23 does not directly scrape the surface of the heating element 22, but slides on the surface of the heating element 22. When impurities are attached to the surface of the heating element 22, the position of the impurities will conflict with the position of the scraper 23, so the scraper 23 can move to remove the impurities.

[0025] Please see Figure 4 A further solution based on this embodiment is: the limiting cylinder 31 has a groove at the corresponding position of the threaded cylinder 34, and the threaded cylinder 34 slides inside the groove. The groove can prevent the threaded cylinder 34 from rotating, so that when the threaded rod 33 rotates, the threaded cylinder 34 slides and will not rotate with the threaded rod 33.

[0026] Please see Figure 2 , Figure 5 A further embodiment of this solution is as follows: The condensation assembly includes a condenser pipe 41 installed on the processing tank 1, a partition plate 42 fixedly connected inside the processing tank 1, a mounting bracket 43 fixedly connected to the partition plate 42, and a guide plate 44 fixedly connected to the mounting bracket 43. The guide plate 44 guides the condensed liquid to the gap between the partition plate 42 and the processing tank 1. The condenser pipe 41 condenses the vapor into liquid, thereby processing the dust removal liquid of the processing tank 1 in conjunction with the partition plate 42 which is isolated from the lower heating section.

[0027] Please see Figure 5 A further solution based on this embodiment is: a number of through slots are provided on the guide plate 44, and the through slots are evenly distributed from top to bottom. If the evenly distributed through slots allow the vapor to pass through evenly, the condensed liquid cannot pass through the guide plate 44.

[0028] Working principle: Seawater is transported to the inside of the treatment tank 1 through an external pipe connected to the inlet 6, so that the added seawater comes into contact with the heating element 22. The heating element 22 then heats the seawater. The water vapor generated by heating rises through the partition plate 42 and the guide plate 44, and condenses into liquid upon contact with the condenser tube 41. The liquid is then guided by the guide plate 44, so that the condensed liquid is stored between the partition plate 42 and the treatment tank 1 and can be discharged through the drain port 5. The mounting plate 21 is removable. After a certain period of use, the mounting plate 21 can be removed to thoroughly clean the heating element 22. The external hexagonal rotating block 32 is turned by using a wrench or other tools. The external hexagonal rotating block 32 drives the threaded rod 33 to rotate. The threaded rod 33 drives the threaded cylinder 34, which pushes the scraper 23. The scraper 23 slides on the surface of the heating element 22, thereby scraping off larger impurities on the surface of the heating element 22.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
