摘要：低溫液體儲罐是一種專門貯存和供應(yīng)低溫液化氣體的夾套式真空絕熱壓力容器。在工業(yè)生產(chǎn)和日常生活中，已被廣泛應(yīng)用。本文旨在對低溫液體儲罐設(shè)計進(jìn)行研究，以21立方米液態(tài)乙烯儲罐的設(shè)計為例，具體分析了低溫儲罐的現(xiàn)狀及發(fā)展前景。并探討了低溫存儲設(shè)備的設(shè)計選材，其中主要包括筒體、封頭以及保溫層材料的選擇等。接著研究了儲罐的結(jié)構(gòu)設(shè)計,其中包括容器的總體形狀、內(nèi)外筒體封頭的選擇等。最后，按照工藝設(shè)計、設(shè)備結(jié)構(gòu)設(shè)計、強(qiáng)度計算與校核的順序，分別對儲罐的筒體、封頭、吊帶、安全閥、開孔補(bǔ)強(qiáng)等進(jìn)行了分析計算。低溫工作中的安全問題是非常重要的，本文對設(shè)備的安裝使用及維護(hù)也做了詳細(xì)介紹。 設(shè)計結(jié)果滿足工廠要求，安全性、經(jīng)濟(jì)型及環(huán)保要求均合格。 關(guān)鍵詞： 低溫儲罐 結(jié)構(gòu)設(shè)計 開孔 強(qiáng)度計
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
