| titleOfInvention | System and method for preparing high-purity vanadium electrolyte by efficient clean chlorination method |
| abstract | The invention belongs to the fields of chemical industry and energy, and provides a system and a method for preparing high-purity vanadium electrolyte by using an efficient clean chlorination method. Preparing high-purity low-valence vanadium oxide powder by adopting chlorination, dedusting leaching, purification, catalytic oxidation, fluidized reduction and fluidized bed dissolving processes, wherein the average valence state of vanadium is any value within the range of 3.0-4.0; ultrapure water and pure sulfuric acid are added into the liquid-solid fluidized bed to dissolve low-valence vanadium oxide at low temperature to obtain high-purity vanadium electrolyte which can be directly used for the all-vanadium flow battery. The invention realizes the regeneration of chlorine by introducing clean oxygen-enriched air into the catalytic oxidation fluidized bed, finally realizes the circulation of chlorine and reduces the production cost; the hydrochloric acid condensing and absorbing tower is used for recovering hydrogen chloride in the catalytic oxidation tail gas, the generation of vanadium-containing hydrochloric acid is eliminated, and the environmental protection cost is greatly reduced. The method has the advantages of strong raw material adaptability, low production energy consumption and operation cost, stable product quality and the like, and is suitable for large-scale industrial production of the high-purity vanadium electrolyte. |
