Abstract

The invention belongs to the field of salt lake lithium-extraction equipment, and particularly relates to an ion concentration polarization effect based salt lake lithium-extraction device. The ion concentration polarization effect based salt lake lithium-extraction device comprises a main channel, wherein a first buffer solution tube, a brine tube for introducing an extracting stock solution intothe main channel, a lithium-rich solution cavity tube and a second buffer solution tube are sequentially arranged on the main channel; the two ends of the main channel are separately equipped with afirst outlet and a second outlet; and a first negative ion selective block with a plurality of channels and a second negative ion selective block with a plurality of channels are arranged inside the main channel. Locally reinforced electric fields, caused by ion concentration polarization effect, in the channel are utilized to realize lithium iron enrichment and lithium-magnesium separation; and the solution is driven to flow through pressure intensity at the inlet and outlets, and a lithium solution with high concentration is collected by an opening in a pipeline. For different direct parallel layout of micron-level channels, a great number of micron-level channels are processed on an ion selecting material, so that large-scale parallel layout of the micro channels is realized.

Description

technical field [0001] The invention belongs to the field of salt lake lithium extraction equipment, and in particular relates to a salt lake lithium extraction device based on ion concentration polarization effect. Background technique [0002] Lithium battery is a high-quality energy source developed in the 1930s and 1940s. It has been widely used in various fields due to its high open circuit voltage, high specific energy, wide operating temperature range, balanced discharge, and self-discharging electrons. It is a promising power battery. [0003] There are many salt lakes in my country, all types, rich resources, and rich in rare elements. The lithium salt reserves of salt lakes account for more than 80% of the total lithium resources in my country and 1 / 3 of the world's total lithium reserves in salt lakes. At present, the proven global lithium reserves have reached 14 million tons. my country's lithium reserves are 3.2 million tons, ranking second in the world after...
