摘要
本文采用了流化床反应器代替传统的卧式氟化炉反应器制备氟化钕。在常温条件下,采用空气作为流体介质,考察了原料氧化钕在流化床反应器中不同气速下的流化状态和膨胀情况,从而确定流化介质的最佳速度及加料量。在冷模基础上进行热模实验,考察不同反应温度、反应时间等参数条件对稀土氟化反应的影响,为下一步的反应器的放大提供技术参数。
This paper designs and homemade reactor of fluidized bed replaces the traditional reactor of fluoride furnace for preparation the neodymium fluoride. Under normal temperature and different velocity, air was chosen as medium, compared the fluidized and inflated state in fluidized bed, confirm the best velocity and stuffing. Gone with hot-model experiment for confirming temperature and time on the basis of velocity and stuffing confirmed in the cold-model experiment, compared the fluorination rate of neodymium fluoride. Anything we have done for the reactor of fluidized bed can be enlarged.
