Vanadium slag treatment and vanadium liquid preparation device

Abstract

The invention provides a vanadium slag treatment and vanadium liquid preparation device, which belongs to the technical field of vanadium liquid preparation and comprises a kettle body, a heating jacket, a material bin and an inner container. The heating sleeve is used for heating liquid and making the liquid generate steam. The material bin is limited in the kettle body, a preparation cavity used for containing vanadium slag is formed in the material bin, and a filtering hole and an exhaust hole which are communicated with the preparation cavity are formed in the bottom and the top of the material bin respectively. The inner container is arranged in the kettle body; the top of the inner container penetrates through the material bin and is communicated with the preparation cavity; a circulation cavity is defined by the outer wall of the material bin, the inner wall of the kettle body and the inner container. The heating sleeve is used for increasing the pressure in the circulation cavity through generated steam and making liquid flow into the liquid inlet, and the inner container drains the liquid to the preparation cavity so that the liquid can make contact with vanadium slag and produce vanadium liquid. According to the vanadium slag treatment and vanadium liquid preparation device, through the components such as the inner container, the kettle body and the heating sleeve, high-temperature liquid continuously flows through the vanadium slag, continuous leaching of vanadium is guaranteed, and the leaching efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of vanadium liquid preparation, and more particularly relates to a vanadium slag treatment and vanadium liquid preparation device. Background technique [0002] Vanadium pentoxide is an indispensable raw material for modern industry. Vanadium metal or vanadium compound is widely used in high-end fields such as steel industry, chemical industry, aerospace and large-scale energy storage. Vanadium-containing solution is the raw material for producing vanadium pentoxide. At present, most of the processes used in the vanadium chemical industry at home and abroad include the steps of leaching, filtration, purification, vanadium precipitation and calcination. [0003] In the traditional vanadium extraction process, vanadium slag needs to be leached, in order to obtain a higher concentration and pure vanadium-containing solution, and then the slurry is filtered. However, due to the slow filtration speed and other r...
