摘要

本文主要从AlF3∙3H2O晶体脱水过程的物理和化学方面进行研究。首次提出了一种高效的AlF3∙3H2O晶体单段干燥焙烧新方法。该方法采用了原设计的逆流鼓式干燥-煅烧炉。该方法保证了高质量的产品(97%以上的AlF3具有高流动性)和低热损失，因为在一个干燥-煅烧炉中结合了干燥和煅烧过程。对该方法的经济因素进行了评价，并与现有方法进行了比较。

Improvements in Technology of AlF3 from FSA

In this paper we focus on physical & chemical aspects of AlF3∙3H2O crystals dehydration process. A new highly efficient single-stage method for drying and calcination of AlF3∙3H2O crystals is presented for the first time. In this method a countercurrent drum dryer-calciner of original design is used. The method ensures high quality product (more than 97 % of AlF3 with high flowability) and low heat loss due to combining both drying and calcination processes in one dryer-calciner. Economic factors of this method are assessed and compared with existent methods.
