摘　　要：合成氨工业的快速发展导致其核心设备氨合成塔的容器直径、壁厚及重量不断增加,本文针对现有的几种设备筒体结构(筒节锻焊式、厚板卷焊式、层板包扎式、热套式和扁平绕带式)进行设计对比分析得出:扁平绕带式筒体结构更适合容器大型化发展要求。Large-sized ammonia synthetic tower is inexorable trend of industrial development.In this arti-cle,the author gives comprehensive comparison among the main existing constructions of tower,such as concentric wrapped shell,shrink fit shell,monobloc welding shell,monobloc forge welding shell and flat steel ribbon wound cylindrical shell.The results show that the flat steel ribbon wound shell is more suit-able to be large-sized for its simplicity in manufacturing and safety in designing.
