BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, the present invention will be described with reference to the drawings for explaining a seawater desalination apparatus according to embodiments of the present invention.

2 is a view showing a seawater desalination / water intake apparatus according to an embodiment of the present invention.

The seawater desalination apparatus for seawater desalination according to an embodiment of the present invention may include a water intake unit 210 and a support unit 220.

The water intake part 210 introduces seawater in the seabed through the intake port 212 into the interior. A plurality of intake ports are formed along the circumference of the intake section. In FIG. 2, the water intake unit 210 has a circular cross-sectional shape. When the water intake unit 210 is formed in a circular shape, sea water can be introduced from all directions in the sea floor through a plurality of water intake holes 212 formed along the circumference . However, it is not limited to this, and it may be formed in a polygonal shape.

The water intake part 210 is supported by the support part 220 so as to be spaced apart from the seabed surface and is preferably formed at an appropriate depth to obtain a smooth water intake and good quality seawater.

For example, the water intake part 210 should be located at a predetermined distance from the sea surface (at least 4 m or more from the sea surface) so as not to be affected by the wave height, and the sand, foreign matter, And at least 2 m from the surface.

2, the water intake part 210 according to the present invention will be described in more detail. In the present invention, the water intake part 212 is inclined toward the center of the water intake part 210 toward the upper part thereof, And may be formed as a plurality of peripheries. The upper surface 214 forms an upper surface of the water intake portion 210 and the upper surface 214 may have a plurality of water intake holes 215 formed therein. In the case of aquatic organisms, it is known that there is no resistance to the turbulence in the depth direction. Therefore, the water intake hole 215 formed in the upper surface 214 may be formed as a hole having a small radius that does not allow entry of substances that affect aquatic organisms and other water quality.

The Environmental Impact Assessment (EIA) takes measures to avoid or reduce harmful environmental impact by pre-examining, predicting and evaluating the environmental impact of the implementation of environmental impact assessment projects stipulated in the Environmental Impact Assessment Act It is the evaluation procedure according to the law to be carried out. The present invention relates to a water resource development project and may be an object of environmental impact assessment, so that the present invention reduces the impact on the water ecological environment to a minimum, as described above.

The lower support member 216 has a hollow formed such that the area formed by the circumference is larger than the cross-sectional area of the upper surface 214 and the seawater flows into the interior.

Here, the cross-sectional area of the upper surface 214 does not mean the area of the upper surface 214 but means the maximum area formed by the circumference when the upper surface 214 is cut in the lateral direction. For example, as shown in FIGS. 5 and 6, when the top surface 214 is conical, the cross-sectional area of the top surface 214 refers to a surface formed by the bottom surface of the cone.

A plurality of partition members 218 are formed between the upper surface 214 and the lower support member 216 so that the partition member 218 is spaced apart from the upper surface 214 by a predetermined distance. A plurality of water intake ports 212 can be formed along the periphery of the water intake section 210. Although only the vertical partitioning member 218 is shown in the drawing, it is needless to say that the partitioning member may be additionally provided in the lateral direction to increase the structural rigidity.

The size of the water intake port 212 divided by the partition member 218 can be larger than the water intake hole 215 formed in the upper surface 214 described above because the aquatic organisms are known to be highly resistant to the horizontal turbulence.

Therefore, in the present invention, since the center of the lower support rod 216 and the upper surface 214 coincide and the area formed by the periphery of the lower support rod 216 is formed larger to accommodate the upper surface 214, 218 may be inclined toward the center of the water intake part 210 toward the upper part.

The support part 220 is formed in a columnar shape so as to support the water intake part 210 from the sea floor and the upper part is embedded in the sea bottom surface and the seawater introduced from the water intake port 212 of the water intake part 210, A hollow is formed so as to be moved downward. The support part 220 is connected to the water intake pipe 230 buried beneath the seabed so that the seawater moved below the seabed surface is transferred to the land or other places to be desalinated.

2, a water intake system for seawater desalination according to the present invention will be described in comparison with the conventional system shown in FIG. 1. When the water intake ports 212 are formed at the same height, in the present invention, The cross sectional area of the water intake port 212 can be widened and the inclined surface is directed upward. Therefore, the flow of seawater directed to the sea floor can be naturally induced, thereby improving the water intake efficiency. Also, as described above, in the present invention, seawater can be collected from the upper surface 214 through the water intake hole 215, thereby further improving the water intake efficiency.

Next, a seawater desalination apparatus for seawater desalination according to another embodiment of the present invention will be described with reference to FIGS. 3 and 4. FIG. FIG. 3 is a perspective view showing a seawater desalination / water intake apparatus according to another embodiment of the present invention, and FIG. 4 is a front view of FIG.

Hereinafter, the description of the present embodiment will be described focusing on the differences from the above-described description with reference to FIG.

Compared with FIG. 2, the top surface 214 is identical in appearance and the present embodiment has a lower side 219 instead of the lower support 216 in FIG.

3 and 4, in the present embodiment, the lower surface 219 is formed such that the area formed by the upper circumference is larger than the sectional area of the upper surface 214, and the area formed by the circumference becomes smaller An inclined surface is formed on the side surface. That is, the inclined surface is formed so as to be directed toward the center of the water intake part 210 toward the lower part. In this embodiment, a water intake hole 215 having a smaller cross-sectional area than the water intake hole 212 may be formed on the lower side surface for the same reason as that formed on the upper surface 214 as described above.

Below the lower side 219 a support 220 is connected which supports the intake 210 including the upper surface 214, the partition 218 and the lower side 219.

At this time, in this embodiment, the seawater flowing upward from the sea floor toward the water intake portion 210 can be introduced through the water intake hole 215 formed in the lower side surface 219, thereby further improving the water intake efficiency. In addition, as described above, the size of the water intake hole must be small so that aquatic organisms and pollutants do not flow through the water intake hole 215.

Next, a seawater desalination apparatus for seawater desalination according to another embodiment of the present invention will be described with reference to Figs. 5 and 6. Fig. FIG. 5 is a perspective view illustrating a seawater desalination / water intake apparatus according to another embodiment of the present invention, and FIG. 6 is a front view of FIG.

Hereinafter, the description of the present embodiment will be described focusing on the differences from the above-described description with reference to FIG. 3 and FIG.

In this embodiment, the shape of the upper surface 214 is different from that of FIGS. 3 and 4. 5 and 6, the shape of the top surface 214 may be conical. Although not shown, it may be in the form of a truncated cone, or a conical or truncated upper surface 214 may be formed in place of the embodiment of FIG.

When the top surface 214 is formed in the shape of a cone or truncated cone, the area formed by the top surface 214 can be further enlarged. Therefore, the amount of seawater flowing through the upper surface 214 can be further increased, and the water intake efficiency can be further improved.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
