Refining slice vanadium Vanadium pentoxide dry calcination introduced: Using a dry, decompose, rapid melting technology equipment fabrication vanadium piece, is an internationally advanced level of process equipment. Traditional process method is one-step process, produced during the prophase of partial vanadium or more Vanadium acid ammonium water filter cake into reverberatory oxpatiation long finish drying, heat gradually took off Ammonia, melting process. The one-step simple process, the main problems of 1.the high energy consumption, energy utilization ratio less than 30%. 2. Low reclamation, currently can achieve recovery in 95% ~ 97% 3. Environmental pollution, melting vanadium generated in ammonia universal emissions into the air, cause air pollution 4. Working environment is poor, because sealing is bad, produce the dust and smoke affect the environment and workers' health My company design of preparing slice vanadium three-stage method to process Three-stage method to process, namely dry, take off ammonia, melt, divide three process finished 1. The first will vanadium bread by drying machine to dry powder 2 the take off ammonia equipment off ammonium 3. By melting furnace melting A, dry Using flash drying method, forthcoming vanadium bread by feeding into dry inside machine, heating of hot air into the dryer. In mechanical scattered, under the action of vanadium bread into powder, forming a rapid drying powder more vanadium acid amines. Second, take off ammonia Using flash perez DE stoves calcining stoves, will achieve rapid off ammonium dried powder vanadium continuous into off ammonium furnace, the heating of the heat air into the furnace, take off ammonium with into furnace in rapid mix, powdery vanadium continuous flow, achieve rapid decomposition by dozens of seconds after decomposed into V2O5 powder vanadium Three, melt In the melting process mainly adopts three-phase arc furnace, radiant tube melting furnace, flash melting furnaces. Radiant tube melting furnace, flash melting furnaces is rapidly melting vanadium piece of new furnace type, mainly by the flash melting chamber, heat preservation of molten pool constitutes. Three-stage method to new technology Adopt three-stage method to process can improve the efficiency of vanadium pieces produced using flash melting furnaces, the heat generated by the air can as dry heat, namely effective use hot and effective recovery in the air gasification ammonia, has remarkable economic benefits.
