| titleOfInvention | A kind of system and method for the efficient chlorination vanadium extraction of vanadium slag |
| abstract | The invention belongs to chemical industry, field of metallurgy.Specifically, the invention discloses a kind of system and method for the efficient chlorination vanadium extraction of vanadium slag.Realize that chloridating gas are preheated by chloridating gas and chlorination flue gas heat exchange, it is appropriate part coke powder burning is realized that the heat balance of chlorination process is supplied with addition of air, improve vanadium slag chlorination efficiency and ensure the selectivity of chlorination, and recycling for chloride slag integrated treatment and chlorine is realized simultaneously by the high-temperature fluidizedization oxidation processes of chloride slag, and powdery vanadic anhydride product and hydrochloric acid byproduct are directly prepared by the vapor phase hydrolysis of chlorizate vanadium oxytrichloride, effectively improve chlorination reaction efficiency, reduce chlorine consumption, the ammonia and nitrogen pollution problem for eliminating chloride slag harm and avoiding traditional ammonium salt sealed Belt from.The present invention is applied to contain V 2 O 5 The chlorination of 10wt%~28wt% Vanadium in Vanadium Residue is extracted, and has the advantages that efficiency high, energy consumption be low, pollution-free and good economy performance. |
