Abstract

The invention relates to a vanadium sodium separation device and method, which is beneficial to solving the problems that the process flow is long, the energy consumption is high and the vanadium recovery rate is low in the existing vanadium sodium separation process, beneficial to obtaining optimal vanadium sodium separation effect and improving vanadium recovery rate with simple process and low energy consumption, thus conforming to national policy of energy conservation and emission reduction. The invention is characterized in that the vanadium sodium separation device comprises a nanofiltration membrane separation system, the raw liquor inlet of the nanofiltration membrane is connected with a raw liquor pipeline by virtue of a pressure pump, the sodium permeate outlet of the nanofiltration separation system is connected with a sodium permeate pipeline, and the vanadium strong liquor recycling port of the nanofiltration separation system is connected with a vanadium strong liquor recycling pipeline.

Description

technical field [0001] The invention relates to vanadium-sodium separation technology in vanadium-sodium solution, such as vanadium-sodium separation in wet vanadium extraction process, vanadium-sodium separation in water treatment process, etc., especially a vanadium-sodium separation device and method. Background technique [0002] Vanadium is an important strategic resource, widely used in steel, alloy, chemical industry, vanadium battery and other industries. Vanadium is widely distributed in nature, accounting for about 0.02% of the mass of the earth's crust, but its distribution is very scattered, mainly in association with metal ores such as iron, titanium, uranium, molybdenum, copper, lead, zinc, aluminum, etc., or with carbonaceous Coexistence of ore and phosphate rock. Therefore, how to separate vanadium from other elements is the key to realize the application value of vanadium. [0003] Due to the different composition and structure of various minerals, the met...
