| titleOfInvention | System and method for producing high-purity energy storage material for flow battery by using high-chromium vanadium slag |
| abstract | The invention discloses a system and a method for producing a high-purity energy storage material for a flow battery by using high-chromium vanadium slag. Vanadium, chromium and iron in the high-chromium type vanadium slag are converted into corresponding gaseous chlorides through selective chlorination by the circulating fluidized bed, most of impurities such as manganese, titanium, silicon and the like in the vanadium slag are left in chlorination residues, and separation of valuable elements and other impurities is realized. The gaseous chloride is subjected to high-temperature dust collection to separate crude chromium trichloride, medium-temperature dust collection to separate crude ferric trichloride and low-temperature leaching to separate crude vanadium oxychloride. Volatilizing and purifying the crude chromium trichloride to obtain high-purity chromium trichloride; volatilizing and purifying the crude ferric trichloride to obtain high-purity ferric trichloride; and rectifying, purifying and catalytically oxidizing the crude vanadium oxychloride to obtain high-purity vanadium pentoxide powder. The invention realizes high-valued comprehensive utilization of the high-chromium vanadium slag, and the high-purity energy storage material for the flow battery is produced and obtained by a one-step chlorination-multi-stage recovery method. |
