Description

[Technical Field]

[0001] The present invention relates to an apparatus that enables separation of salinity by stirring the salinity of seawater. [Background technology]

[0002] In recent years, areas suffering from water shortages and difficulties in water supply after disaster recovery have become an issue. In response, we wondered whether it would be possible to turn seawater from the ocean nearby into freshwater, and came up with this technology.

[0003] It will be possible to supply equipment at low cost, which is expected to help solve future water shortages. Currently, the mainstream technology for desalination of seawater is using reverse osmosis membrane equipment, but this is expensive and requires maintenance such as filter replacement, making it unsuitable for sudden water shortages or disasters.

[0004] For this reason, most reverse osmosis membrane devices today are large, stationary units that cannot be moved. Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above circumstances, the present invention aims to make it possible to produce a wide range of inexpensive and portable devices, from small to large, and also to simplify maintenance. [Means for solving the problem]

[0006] The seawater desalination apparatus according to the present invention, which achieves the above object, is characterized by separating salt contained in seawater.

[0007] Seawater is made up of water as a solvent and chlorine as a solute. All we need to do is separate the solvent and solute.

[0008] Generally, when seawater freezes, the frozen part is water, which is the solvent. Below the frozen part is seawater containing solutes with a high salt concentration.

[0009] This device is characterized by utilizing the temperature difference to separate the above properties into water as a solvent and seawater with a high salt concentration as a solute.

[0010] Let me explain how it works. The device has a container that holds seawater. This container has a layer with gaps, making it a two-layer container. This layer utilizes Peltier elements, with the upper layer being a cooling layer and the lower layer being a heating layer (see Figure 1).

[0011] [Overview of the present invention] The present invention moves salt from the upper side, which is the cooling layer, to the lower side, which is the heating layer.

[0012] The present invention solves the problem of heat diffusion in the aqueous solution due to temperature difference alone by creating a vortex in the lower heating layer, making it difficult for heat to be transferred to the upper cooling layer (see Figure 1).

[0013] The method of creating a vortex was first discovered by utilizing a whisk structure, which prevents heat diffusion (see Figure 1). [Brief explanation of the drawings]

Claims

1. A structure in which seawater is placed in a container with a cooling layer and a heating layer, with the purpose of separating the salinity.

2. A mechanism that agitates the seawater in the heating layer to prevent heat from being transferred to the cooling layer.

3. A mechanism designed to promote the movement of salt from the cooled layer to the heated layer.
