摘要
造粒—干燥机是重过磷酸钙装置的核心设备。分析了造粒—干燥系统的工艺流程、物料平衡和热量平衡,对其主要技术参数(如直径、长度、转速和功率等)进行了设计计算,并为了提高其性能、解决设备的磷酸腐蚀问题,进行了结构优化。生产实践证明,该设备的设计选型是合理的。
The granulation-dryer is the core equipment of the triple superphophate( abbreviated to TSP) plant. The process flow,material balance and heat balance of the granulation-drying system are analyzed. The main technical parameters,such as diameter,length,speed and power,are designed and calculated,and to improve the performance of the equipment and to address the phosphoric acid corrosion issue of the equipment,structural optimization is carried out. Production practice has proved that the design of the equipment is reasonable.
