The invention belongs to the technical field of high-purity vanadium pentoxide production, and specifically discloses a device for highly automated clean production of high-purity vanadium. The highly automated clean production of high-purity vanadium includes a crushing ball mill unit, a ball making unit, a roasting unit, a leaching unit, an ammonium metavanadate preparation unit, and a vanadium pentoxide calcination unit, and finally a vanadium pentoxide product with a purity of 99.9% can be obtained . The highly automated and clean production of high-purity vanadium provided by the present invention reduces the loss of vanadium and the entry of impurities through the mechanized and automatic control of the process, ensures the quality of high-purity vanadium, and realizes the clean and automatic production of high-purity vanadium.
Description
technical field [0001] The invention relates to the technical field of high-purity vanadium pentoxide production, in particular to a production device for highly automated clean production of high-purity vanadium. Background technique [0002] With the continuous expansion of vanadium in the field of scientific and technological applications, the requirements for the purity of vanadium products are getting higher and higher, and the requirements for product purity are more stringent for the automation level of the preparation process and equipment. [0003] The application number is CN201410172014.1 "A method for producing high-purity vanadium pentoxide by using vanadium-containing waste slag", in which the calcium slag in the prior art has a long filtration time and a large amount of washing water, low vanadium recovery rate, and high purity of vanadium pentoxide. For lower problems, use the vanadium-containing calcium slag discharged from the production process of sodium d...
