| titleOfInvention | TECHNOLOGICAL SITE FOR THE PRODUCTION OF PANAOXIDE VANADIUM |
| abstract | The proposed utility model relates to the field of metallurgy, and, in particular, to technological and production sites, departments, complexes for producing commercial vanadium pentoxide from vanadium-containing raw materials - technical vanadium oxytrichloride. The developed technical solution can be used at chemical and metallurgical enterprises. The objective of the proposed utility model is the development of a new technological area for the production of commercial vanadium pentoxide of their technical vanadium oxytrichloride containing 30-90% VOCl 3 , 10-70% TiCl 4 and impurities of chlorides and oxychlorides of other metals. The technical result that can be obtained by implementing the proposed utility model consists in the selective extraction of vanadium compounds from the initial vanadium-containing raw materials and in the process of obtaining liquid marketable products from the generated production wastes that are in demand among consumers - granular vanadium-containing catalysts for fine organic synthesis. The problem is solved with the achievement of the above technical result by the proposed utility model - "Technological site for the production of vanadium pentoxide", which includes the following main technological equipment: a reactor with a stirrer for alkaline treatment of vanadium oxytrichloride, which has a sealed connection with a transported container with vanadium oxytrichloride, vanadium oxytrichloride exit from transported tank to the reactor for alkaline treatment through shut-off and control valves directed to a distribution device located in the reactor below the level of the stirrer; on the lid of the reactor for alkaline treatment of vanadium oxytrichloride there is a nozzle for connecting to a sequentially installed batcher and a stirrer tank for the preparation of sodium hydroxide solution; the ammonium metavanadate crystallizer tank, on the lid of which there are nozzles, one of which has a connection to the collection tank of the sodium metavanadate solution, and the other pipe is connected to a dispenser of ammonium chloride, the pipe for lower discharge of the suspension from the tank the crystallizer is connected to filter-1 for separating and washing the ammonium metavanadate precipitate; after filter-1, a ammonium metavanadate precipitating tank is installed, connected through nozzles installed on the tank lid with a demineralized water distribution line and an ammonium chloride dispenser, and the suspension is drained through lower discharge nozzles the crystallizer tank is directed to filter-1, which is technologically connected to the calcining furnace, after filter-1, a collection tank for the mother liquors and an ammonium metavanadate feed, and a neutralization reactor are installed vanadium-containing solutions and wastewater, connected to a solution dispenser containing iron (II) salts and sodium hydroxide solution, filter-2 for separating iron oxyhydrate with impurities of vanadium compounds from the pulp, characterized in that after the reactor for alkaline treatment of technical vanadium oxytrichloride is installed filter-3 for separating titanium oxyhydrate precipitate from the resulting pulp and washing it, the output from filter-3 of a solution of sodium metavanadate, purified from the solid phase, is sent to a collection container connected with a crystallizer tank, the filter trough 3 has a discharge hatch equipped with a shut-off and dispenser that directs the wet sediment of titanium oxyhydrate to the collector and to a heated reactor-repulpator with a stirrer connected to a sodium hydroxide solution dispenser and filter-3 equipped with a discharge unit having a connection with a screw mixer, to which a Portland cement dispenser is connected, the inlet to the dispenser is directed from the portland cement consumable hopper, the composite mixture exit from the screw mixer is directed to a granulator made in the form of an extruder, after which a belt conveyor, classifier, hopper-collector of finished commodity products, a collector of small (substandard) non-commercial fractions technologically connected to a screw mixer, the hopper-collector of finished commodity products has a connection through the discharge hatch and a shut-off and regulating fittings with a device for packing. |
