| titleOfInvention | A kind of method of chlorination production high purity vanadic anhydride |
| abstract | The invention provides a kind of by chlorination to extracting and be converted into the novel method of high purity vanadic anhydride containing vanadium material.High purity vanadic anhydride technique of the present invention, its technical process comprises batching, chlorination, dedusting, condensation, rectifying, hydrolysis, filtration, oven dry and aftertreatment.Raw material composition is by containing vanadium material, carbon simple substance in mass ratio 1: (0.05-0.25) mixes drying and join in reactor, successively by high purity vanadic anhydride by the time after chlorination, rectifying, hydrolysis and aftertreatment.The invention provides the novel method that a kind of unorthodox method produces Vanadium Pentoxide in FLAKES, decrease in conventional wet metallurgical process the industrial harmful waste water formed, chlorine realizes recycle after treatment.Whole production process technology is simple, and basic no waste produces, and has certain economic benefit and social benefit.The powder vanadium pentoxide purity that this kind of method obtains is 99.5%-99.99%. |
