摘　　要：介绍了偏钒酸铵制备粉状五氧化二钒的制备工艺,对传统设备与新型回转炉设备的运行参数进行了优劣对比,并对进料系统、炉管、原料回收及尾气处理系统的优化设计及连续化生产应用进行阐述。片状五氧化二钒为生产钒合金的原料,而粉状五氧化二钒则是片状五氧化二钒的直接原料,间接影响钒合金的性能。目前批量生产方式较为落后,其整体生产效率低、自动化水平低,导致运营成本居高不下。连续制备粉状五氧化二钒的回转炉装备主要优点在于:物料破碎充分,螺旋进料顺畅;设备连续批量产出高质量粉状五氧化二钒,产量达到340 kg/h以上;尾气中回收物料可再次作为原料进行利用,尾气处理后达到国家排放标准。连续式回转炉可实现粉钒连续化制备,对钒氮行业具有积极意义。It summarizes the preparation process of powdered vanadium pentoxide by using ammonium metavanadate,compares the operation parameters of traditional equipment and new rotary furnace,and elaborates the optimal design and continuous production application of feeding system,furnace tube,raw material recovery and tail gas treatment system.The Flake Divanadium pentaoxide is the raw material of vanadium alloy,and the powder divanadium pentaoxide is the direct raw material of the divanadium pentaoxide,which affects the properties of vanadium alloy indirectly.The current batch mode of production is relatively backward,with low overall production efficiency and low levels of automation,leading to high operating costs.The main advantages of the rotary divanadium pentaoxide equipment for continuous powder divanadium pentaoxide are:the material is fully broken and the spiral feed is smooth;The recovered material in tail gas can be used as raw material again and the tail gas can meet the national emission standard after treatment.Continuous rotary furnace can realize the continuous preparation of vanadium powder,which has a positive significance for vanadium and nitrogen industry.
