碱式硫酸铬的造粒干燥装置—带附壁风的压力式喷雾干燥器

A granulating device for drying of chromic sulfate basic salt Carring adhesive wind and pneumatic-type spray dryer

通过对颗粒状碱式硫酸铬的热稳定性测定以及数据整理 ,并对原有干燥设备进行了原理分析 ,提出了一种新型塔结构设计及操作工艺条件 ,并在亭江化工厂进行了生产实践考核 ,该装置不仅能严格调整和控制排风温度 ,从而获得优质颗粒状碱式硫酸铬制品 ( dp=12 0 μm) ,同时可提高原有干燥设备之蒸发强度 ,达 12～ 16kg- H2 O/ m3h,实现了小设备大生产之效果。

A new tower structure and processing technology were described through the determination of heat stability on granular chromic sulfate basic salt and analysis of data. Application was carried in a chemical factory of Sichuan province. Yield a good results of a large scale production with a small scale equipment.
