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。

ABSTRACT
The purpose of this report is to absorb SO2 from tail gas. It is well known that SO2 is an important factor causing air pollution. It can form acid rain, cause corrosion to open-air objects such as buildings, and seriously endanger people's personal safety and cause serious economic losses to society. Therefore, it is very important to design tower equipment for absorbing SO2. Bulk packing tower is widely used because of its high efficiency, low power and better economy.
This report is mainly divided into four parts: the main structure design, internal structure design, additional device design, and strength check. Among them, the main structure design is mainly for the tower body and the head, mainly for the calculation of its thickness and the selection of manufacturing materials; the internal design is mainly for the design of packing support devices, liquid distribution devices, etc., mainly for the selection of some devices that meet the design standards; the design of additional devices is for the selection of manhole and hand holes, the selection of flanges; the most important part of this report is the design. That is to check the strength, the stress of the tower and its stability.
This report upholds the principle of improving efficiency and reducing energy consumption cost. Through consulting a large number of data, conservative estimation of data is made in a rigorous manner. Through the design improvement of tower equipment, the efficiency of SO2 absorption is greatly improved and energy consumption is saved.
