1400立方米天然氣儲罐設(shè)計（全套CAD圖+說明書+開題報告+翻譯）,立方米,天然氣,設(shè)計,全套,cad,說明書,仿單,開題,報告,講演,呈文,翻譯 1400m3天然氣儲罐設(shè)計 摘要：隨著我國的工業(yè)高速發(fā)展，天然氣已成為石油化工、冶金、城市燃氣等方面的重要原料或燃料，天然氣球罐作為存儲設(shè)備在我國已得到廣泛使用。球形儲罐是一種常見的、基礎(chǔ)簡單、設(shè)計方便、應(yīng)用廣泛的有壓存儲容器。此次天然氣球罐的總體設(shè)計分為設(shè)計選材和結(jié)構(gòu)設(shè)計。球罐殼體材料選用國產(chǎn)16MnR，它具有良好的焊接性能,能較好的保證球罐的焊接質(zhì)量；球罐的結(jié)構(gòu)設(shè)計包含了球殼的設(shè)計、支柱與拉桿的設(shè)計以及球罐附件的設(shè)計。 計算部分是本次天然氣球罐設(shè)計中的重點，也是難點，它分為球罐結(jié)構(gòu)排板計算和強度計算。球罐采用混合式結(jié)構(gòu)，排板計算出各板塊的尺寸是對球罐結(jié)構(gòu)的具體確定；強度計算中需要對球罐進行校核，校核包括支柱穩(wěn)定性校核、支柱與球殼連接校核；設(shè)計中各部分校核都必須合格，從而保障設(shè)計的科學(xué)合理性。 完成了球罐各部分的計算之后，參照相關(guān)的標準對球罐附件進行選用和設(shè)置。待球罐各組成部分都確定了，最后，制定球罐的焊接及制造工藝，對各部件進行焊接組裝。 本次設(shè)計的天然氣球罐，由于天然氣是一種易燃易爆的氣體，其儲存容器必須是無滲漏。因而，在設(shè)計中還必須嚴格對球罐進行壓力試驗和氣密性試驗。試驗都必須合格，這樣，設(shè)計的球罐猜符合要求，才能保證球罐的使用安全。 關(guān)鍵詞：天然氣球罐；材料選用；結(jié)構(gòu)設(shè)計；強度計算；校核 1400 m3 of liquefied natural gas spherical tank design Abstract: With the rapid development of China's industry, natural gas has become the petrochemical industry, metallurgy, city gas, etc. to the important raw material or fuel, natural gas storage tank, as has been widely used in China. Spherical tank is a common and simple, convenient and widely design pressure storage containers. The overall design of the gas discharge into the selection and design of structure design. Spherical shell material, it has good 16MnR homebred the welding performance, can better ensure welding quality of spherical, Structure design of spherical shell contains the ball with the design and the design and spherical tension. Design of attachment Part of this gas discharge is calculated in the design emphasis and difficulty, it is divided into spherical plate structure strength calculation and row. Using hybrid structure, row spherical plate is calculated for each plate size is specific and affirmatory; the structure of spherical Strength calculation of spherical, need checking including pillar stability checking, pillar connecting check with spherical shell, Design of every part of checking must be qualified to guarantee the design of scientific rationality. Complete all parts of the spherical calculation, by referring to the relevant standards for discharge attachments for selection and Settings. For each component is quenched, finally, make sure the sphere of welding and manufacturing process, welding assembly of parts. The design of the gas discharge due to natural gas is a kind of inflammable and explosive gas, its storage containers must be no leakage. Therefore, in the design of spherical must strictly gas-tight test and stress test. Test must be qualified, so, the design of spherical guess accords with a requirement, to ensure the safe use of quenched.
