| titleOfInvention | TECHNOLOGICAL LIMIT FOR PRODUCING PANAOXIDE OF VANADIUM |
| abstract | The proposed utility model relates to the field of metallurgy and chemical technology and can be used at chemical and metallurgical enterprises to obtain commercial vanadium pentoxide from vanadium-containing raw materials, in particular from technical vanadium oxytrichloride (30-90% VOCL 3 + 10-70% TiCL 4 ), formed in titanium production during the purification of technical titanium tetrachloride (TiCl 4 ) from vanadium compounds. The objective of the proposed utility model is the creation of a new technological redistribution, the combination of equipment of which makes it possible to obtain commercial vanadium pentoxide from technical vanadium oxytrichloride. The technical result that can be obtained by implementing the proposed utility model is the separation of vanadium from related impurities - titanium compounds, the content of which in the feedstock - technical VOCl 3 can range from 10 to 70%. The problem is solved with the achievement of the above technical result by the proposed utility model - "Technological redistribution for the production of vanadium pentoxide", including a reactor with a stirrer for alkaline treatment of vanadium oxytrichloride, hermetically connected to the transported capacity of the original vanadium oxytrichloride and connected in series with the dispenser and the tank for preparation and supply sodium hydroxide solution, the ammonia metavanadate crystallizer tank is connected to an ammonium chloride dispenser and a tank for rigotovleniya ammonium chloride solution, the filter 1 to isolate the ammonium metavanadate precipitate from the slurry and washing tank repulpator precipitate ammonium metavanadate, coupled with the filter 1, calcining furnace, a holding tankn n n uterine solutions and ammonium metavanadate feed, vanadium-containing wastewater neutralization reactor - mother liquors and ammonium metavanadate feed connected through a batcher to a collection tank of iron (II) -containing solutions, a batcher and a tank for preparing and supplying sodium hydroxide solution, a filter -2 for precipitation of iron (II and III) oxyhydrates from the pulp with vanadium impurities. New in the proposed technical solution is that the lower discharge pipe of the reactor for alkaline treatment of vanadium oxytrichloride is directed through the pump and shut-off and control valves to filter-3, the trough of which is connected to a collector of titanium cake - a precipitate of titanium oxyhydrate through the discharge-distributing device. which is directed into a heated tank with a stirrer for repulping titanium cake, on the tank lid there is a pipe for connecting a sodium hydroxide solution to the dispenser, draining the pulp from this tank through the pump it is directed to filter-3, the output of the sodium metavanadate solution purified from the solid phase from the filter-3 is directed to a prefabricated-averaging tank connected to the ammonia metavanadate crystallizer tank. |
