本申请属于海上风能利用及海洋锂资源开发领域，具体涉及一种利用海上风电海水提锂的系统及工作方法。
在全球能源低碳转型日益升级的大环境下，风力发电作为可再生能源电力，已成为全球的开发热点，而全球约70％的面积是海洋，海上风能资源十分丰富，尤其在深海区域，风速更大，风力更稳定，更有利于海上风电的发展。
海上风电机组作为一个发电系统，主要由风电机组、塔架和下部结构三部分组成。其中，下部结构分为固定式和漂浮式两种平台结构。目前，近海区域风电场一般采用各种固定于海底的贯穿桩传统结构，但随着水深的增加，采用传统的固定式结构将大幅增加风电场的建设成本，因此在，从投资建设经济性的角度，在深远海域要发展基于漂浮式平台的风电机组。总体来看，风电建设的发展趋势必然是“由陆地向海洋、由浅海到深海、由固定式平台向漂浮式平台”。
锂金属及其化合物广泛应用于各个领域，作为一种重要的战略资源，其需求与日俱增。而全球陆地蕴藏的锂有限，海水中却有丰富的锂，海水提锂是海洋资源化利用的重要组成部分，其技术研究受到国内外很多学者的关注。其中，电化学提锂技术是可充电锂离子电池技术的拓展，利用电极选择性吸附技术，实现了锂离子在海水中的富集。其工艺简单、回收率高、选择性好， 特别适合从低品位的海水中提锂，被认为是很有前途的海水提锂方法。电化学提锂装置主要由吸附装置、回收装置、分离沉淀装置及相关辅助设备组成。工作原理是：海水流经吸附组件时，其中锂离子和氯离子在两端板电驱动作用下分别跨越阳离子、阴离子交换膜运输，由于活性颗粒结构具有很强的锂选择插入特性，迁移后的锂离子会嵌入活性电极颗粒中，随流电极流动，实现锂离子的提取，同时迁移后的氯离子吸附到另一侧流电极的活性炭颗粒上。流电极承载锂离子和氯离子泵入至回收组件在反向的电场作用下将锂离子和氯离子脱出跨膜运输到回收溶液中，在流电极的循环吸附和脱出中，实现氯化锂在海水中的提取和回收溶液中的连续富集。通过分离沉淀装置将高纯氯化锂溶液转化得到碳酸锂粉末。
