摘要:低温液体储罐是一种专门贮存和供应低温液化气体的夹套式真空绝热压力容器。在工业生产和日常生活中,已被广泛应用。本文旨在对低温液体储罐设计进行研究,以21立方米液态乙烯储罐的设计为例,具体分析了低温储罐的现状及发展前景。并探讨了低温存储设备的设计选材,其中主要包括筒体、封头以及保温层材料的选择等。接着研究了储罐的结构设计,其中包括容器的总体形状、内外筒体封头的选择等。最后,按照工艺设计、设备结构设计、强度计算与校核的顺序,分别对储罐的筒体、封头、吊带、安全阀、开孔补强等进行了分析计算。低温工作中的安全问题是非常重要的,本文对设备的安装使用及维护也做了详细介绍。

设计结果满足工厂要求,安全性、经济型及环保要求均合格。

Abstract:Cryogenic liquid storage tank is a kind of special storage and supply of cryogenic liquefied gas jacketed vacuum insulated pressure vessel. In industrial production and daily life, it has been widely used. The aim of this paper is to carry out a research on the design of cryogenic liquid storage tank, take 21 stere liquid ethylene storage tank as an example, specific analysis of the current situation and development prospect of low-temperature storage tank. and discusses  material selection in the design of low temperature storage device,which mainly includes Cylinder, head,steel and insulation material selection. then studies the design of tank structure, which includes a container shape, cylinder head of inner / outer. Finally, according to the process of design, equipment structure of design, strength calculation and checking of the sequence, storage tank barrel body, head, harness, safety valve, opening reinforcement are designed. Low job security problem is very important, On equipment installation and maintenance this article are introduced in detail.

  The design results meet the factory requirements, safety, economy and environmental protection requirements are eligible.

Key words: Cryogenic liquid storage tank   structure design   opening   strength calculation
