DN1200散装填料塔设计
摘要
本说明书设计的是散装填料塔,其设计的目的是吸收尾气中的S,众所周知,S是造成空气污染的重要因素,其可以形成酸雨,可对建筑等露天物体造成腐蚀,并且严重的危害了人民的人身安全,对社会造成严重的经济损失;因此,设计吸收S的塔设备至关重要;而其中散装填料塔因为其工作效率高,工作功率小,且具有更好的经济性,因此而得到了广泛的应用。
本设计主要分为四个部分,即:主体结构设计,内部结构设计,附加装置设计,以及强度校核。其中主体结构设计主要是对塔体,封头的设计,主要是对其厚度的计算以及选用制造材料;内部设计主要是设计填料支撑装置,液体分布装置等,主要是选用一些符合设计标准的装置;附加装置设计是对人孔手孔的选择,法兰的选用等;此报告中最主要的设计部分就是对强度的校核,校核塔体的应力以及其稳定性的校核。
本设计秉承提高效率,降低能耗成本的原则设计,通过查阅大量资料,以严谨的态度对数据进行保守估计,此报告通过对塔设备进行设计改进,大大提高了吸收S的效率,节约了工作时的能耗。
