| titleOfInvention | System and method for purifying vanadium pentoxide |
| abstract | The invention relates to the field of engineering and materials. The invention specifically discloses a system and a method for purifying vanadium pentoxide. According to the invention, industrial-grade vanadium pentoxide is converted into vanadium oxytrichloride through liquidized low-temperature chlorination; chlorination gas preheating is realized through heat exchange between fluidized gas and chlorination flue gas; a proper amount of air is added, such that part of carbon powder is combusted, and balanced heat supply during a chlorination process is realized, therefore chlorination efficiency is improved, and good selectivity of low-temperature chlorination is ensured; vanadium oxytrichloride is subjected to rectification purification, and is oxidized with plasma, such that a high-purity vanadium pentoxide product and chlorine gas are obtained; and the chlorine gas is reused for low-temperature chlorination. The system and method provided by the invention have the advantages of high raw material adaptability, no polluting wastewater discharge, low production energy consumption, low chlorine gas consumption, stable product quality, and the like. The system and the method are suitable for the purification production of 4N and higher high-purity vanadium pentoxide powder, and have good economic efficiency. |
