[0024] A seawater dissolved resource adsorption device (1) is described with reference to Fig. 1.

[0025] FIG. 1 is a drawing showing a seawater dissolved resource adsorption device according to an embodiment of the present invention.

[0026] The seawater dissolved resource adsorption device (1) of the present invention includes an adsorption unit (10) and a fastening part (20).

[0027] The adsorption unit (10) will be explained in detail with reference to FIGS. 2 and FIGS. 3.

[0028] FIG. 2 is a drawing showing an adsorption unit according to an embodiment of the present invention, and FIG. 3 is a diagram illustrating the structure of an adsorption unit according to an embodiment of the present invention.

[0029] The adsorption unit (10) includes a support (110), an adsorption fiber (120), and a connecting part (130).

[0030] The support member (110) is made of a flexible material that can be bent according to the flow of ocean currents and is extended in one direction.

[0031] The adsorption fiber (120) is attached to the support (110) and is connected in a braid type, extending vertically along the longitudinal direction of the support (110).

[0032] As shown in FIG. 3, the area where the adsorption fiber (120) is located in the adsorption unit (10) is rectangular in shape, and the length of the long side / length of the short side may be 3 to 8, 4 to 7, 5 to 6, or 2 to 10.

[0033] In another embodiment of the present invention, the area where the adsorption fiber (120) is located may be elliptical rather than rectangular.

[0034] The connecting part (130) is connected to one end of the support (110) and may be a detachable ring type, but is not limited thereto.

[0035] In another embodiment of the present invention, the connecting part (130) may be magnetic, Velcro, or screw-type.

[0036] The other end of the connecting part (130) is connected to the coupling position of the connecting part (20) described later, so that the adsorption unit (10) is coupled to the connecting part (20).

[0037] The connection of the connecting part (130) and the fastening part (20) also moves in accordance with the flow of the ocean current.

[0038] Hereinafter, the fastening part (20) will be described in detail with reference to FIG. 4, which is a drawing showing a fastening part according to an embodiment of the present invention. FIG. 4 also shows an auxiliary part that will be described later.

[0039] The connecting part (20) provides a connecting position that is connected to the adsorption unit (10) and is fixed to the seabed.

[0040] The connecting part (20) includes a plurality of connecting rods, and the plurality of connecting rods intersect each other to form a grid structure or a matrix structure.

[0041] However, the shape of the fastening part (20) is not limited to this, and in other embodiments of the present invention, the shape of the fastening part (20) may be ladder-shaped.

[0042] Finally, with reference to FIGS. 5 and FIGS. 6, a method for adsorbing dissolved resources in seawater using the adsorption device of the present invention will be described in detail.

[0043] FIG. 5 is a flowchart showing a method for adsorbing dissolved resources in seawater according to an embodiment of the present invention, and FIG. 6 is a drawing showing an adsorption device installed on the seabed according to an embodiment of the present invention.

[0044] The method for adsorbing dissolved seawater resources according to the present embodiment includes an adsorption unit coupling step (S100), a fastening part installation step (S200), a seawater dissolved resource capture step (S300), and a fastening part recovery step (S400).

[0045] In the adsorption unit coupling step (S100), the adsorption unit (10) is coupled to the coupling position of the fastening part (20) outside the ocean, for example, on land or on a ship.

[0046] A plurality of adsorption units (10) are installed on a single fastening part (20) and are connected to the connecting rod of the fastening part (20) at a distance from each other.

[0047] A plurality of adsorption units (10) are combined in a matrix form with the fastening part (20).

[0048] However, this is not limited thereto, and in other embodiments of the present invention, a plurality of adsorption units (10) may be installed spaced apart in one direction of the fastening part (20).

[0049] Next, in the fastening unit installation step (S200), the fastening unit (20) combined with the adsorption unit (10) is introduced into the seabed.

[0050] At this time, the connecting part (20) is connected to the upper part of the connecting part (20) to insert the connecting part (20) into the ocean, and the connecting part (20) is fixed to a fixed part installed on the seabed.

[0051] As shown in FIG. 6, the auxiliary part may be in the shape of a chain that can be coupled to the fastening part (20).

[0052] The auxiliary unit can be connected to a crane installed on the ship.

[0053] The fixed part is installed in a vertical direction on the seabed and connected at both ends of the fastening part (20) to position the fastening part (20) in a vertical direction on the seabed.

[0054] However, the installation step is not limited to this, and the fastening part (20) can be fixed to the side rock wall or structure inside the seawater without a fixed part.

[0055] One or more fastening parts (20) combined with an adsorption unit (10) installed on the seabed may be installed.

[0056] As shown in FIG. 7, which illustrates a method for adsorbing dissolved resources in seawater according to another embodiment of the present invention, a plurality of adsorption devices (1) can be installed in parallel on the seabed and spaced apart from each other.

[0057] Next, in the seawater dissolved resource capture step (S300), the entire adsorption unit (10) moves according to the flow of the ocean current, and the seawater dissolved resources are adsorbed into the interior of the adsorption fiber (120).

[0058] For example, if the support (110) of the adsorption unit (10) floats parallel to the seabed in a streamlined shape due to the ocean current, the adsorption fiber (120) also floats in accordance with the bent shape of the support (110), and seawater dissolved resources can be adsorbed in a transverse direction parallel to the seabed.

[0059] Finally, in the connection part recovery step (S400), the connection part (20) connected to the adsorption fiber (120) that has captured the seawater dissolved resources is pulled up from the seabed.

[0060] At this time, after releasing the fixation of the fastening part (20) fixed to the fixed part, the seawater inner side rock wall or structure, the fastening part (20) is recovered from the ocean by connecting an auxiliary part to the top of the fastening part (20).

[0061] According to the present invention, a transverse adsorption method utilizing ocean current flow can be implemented, and it can be installed even in seabed locations where it is difficult to recover existing dissolved seawater resources.

[0062] By connecting braid-type fiber adsorbents in short lengths, entanglement can be prevented during adsorbent loading / retrieval, and the maximum utilization of seawater volume suitable for the environment can be achieved by adjusting the spacing between the connecting part (20) and the adsorption unit (10).

[0063] Foregoing, specific parts of the present invention have been described in detail. It will be apparent to those skilled in the art that such specific descriptions are merely preferred embodiments and do not limit the scope of the invention. Accordingly, the actual scope of the invention is defined by the appended claims and their equivalents.
