Title:
SYSTEM FOR EXTRACTING LITHIUM FROM SEAWATER BY USING OFFSHORE WIND POWER AND WORKING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/185097
Kind Code:
A1
Abstract:
Disclosed in the present invention are a system for extracting lithium from seawater by using offshore wind power and a working method. According to the present invention, lithium ions and chloride ions in the seawater are respectively adsorbed on a positive electrode plate and a negative electrode plate by means of a lithium adsorption device, and a flow electrode bearing the lithium ions and the chloride ions in the lithium adsorption device enters a lithium recovery device; and under the action of a reverse electric field, the lithium ions and the chloride ions are separated and transported into a recovery solution in a transmembrane manner to form a lithium chloride solution, such that the extraction of lithium chloride in the seawater and the continuous enrichment of lithium chloride in the recovery solution are realized. According to the present invention, offshore wind power and a seawater lithium extraction system are coupled together, abundant offshore resources are fully utilized, electric energy generated by a seawater wind power generator set is used to carry out electrochemical lithium extraction on the seawater, and the lithium extraction system is driven to continuously and normally operate, such that lithium carbonate is continuously generated, lithium metal is extracted from the seawater, and comprehensive resource utilization of the ocean is assisted.
