Onshore lithium-recovering apparatus for lithium ion adsorption and desorption process and lithium-recovering method using the same

An onshore lithium-recovering apparatus for a lithium ion adsorption and desorption process comprising:

• a supply unit for supplying lithium-containing water in which lithium is dissolved;
• a composite unit disposed on land, in which the lithium-containing water is introduced to adsorb the lithium dissolved in the lithium-containing water, and which desorbs the lithium again to discharge a lithium extract liquid;
• a washing unit disposed at one side of the composite unit, provided with a supply pipe to supply fresh water to the composite unit and to wash the composite unit;
• a desorbing liquid unit disposed at one side of the washing unit and which stores desorbing liquid or transfers the desorbing liquid through the supply pipe to supply the desorbing liquid to the composite unit;
• an extract liquid unit disposed at one side of the composite unit and which receives and stores the lithium extract liquid generated by passing the desorbing liquid supplied from the desorbing liquid unit through the composite unit;
• a pressure adjusting unit disposed at one side of the composite unit and which adjusts the flow of the lithium-containing water by adjusting a pressure in the composite unit;
• a discharge unit communicating with the pressure adjusting unit to discharge the lithium-containing water from which the lithium is recovered;
• and
• a control unit for controlling the flow of the lithium-containing water in the composite unit, the fresh water in the washing unit, and the desorbing liquid in the desorbing liquid unit.
