1、 1500m 3 丙烯球罐设计 摘要 本文首先对球形储罐的特点、发展概况和结构形式进行了简单的介绍，然后 对目前国内外对球形储罐的研究水平进行了研究， 发现目前国内的研究水平和国 外相比还是有一定的差距。对球形储罐设计的意义在于：通常球罐作为大容量、 有压存储容器，在各工业部门中作为液化石油气（LPG） 、液化天然气（LNG） 、液 氨、液氧、液氢、液氮及其他中间介质的贮存,也作为压缩空气、压缩气体（氧 气、氮气、城市煤气）的贮存；在原子能工业中球罐还作为安全壳（分割辐 射和无辐射去的大型球壳）使用，总之随着工业的发展，球罐的使用范围也越来 越广泛。但是目前限制球罐向大型化发展的主要因素有：设

2、计制造规范、球罐用 钢、球罐现场组装和焊接问题、球罐现场热处理、球壳板尺寸精度，因此对球罐 的结构和材料的选用提出了新的要求。 本文主要针对球罐的上支柱连接结构进行 了相应的改进，把 U 形柱结构型式支柱改为长圆形结构型式支柱，在球罐施焊过 程中和球罐受力方面到得了优化。 关键词关键词：球形储罐 应用范围 大型化 支柱结构 Design of 1500m3 Propylene Spherical Tank Abstract First, the characteristics, development of the survey and structural of the Spherical

3、Tank are introduced in this paper. Then the Level of research for Spherical tank at home and abroad were studied. Study found that the level of development, or has a gap compared domestic to foreign. The significance of the spherical tank design are as follows: Usually as a large spherical tank capa

4、city, pressure storage containers, In the industrial sector as liquefied petroleum gas (LPG), liquefied natural gas (LNG), liquid ammonia, liquid oxygen, liquid hydrogen, liquid nitrogen, and other storage media center, also as compressed air, compressed gases (oxygen, nitrogen, city gas . .) of the

5、 storage; In the atomic energy industry, also serves as the containment sphere (division of radiation and no radiation to the large spherical shell), In short With industrial development, the use of spherical tanks are increasingly being used. But the current restrictions on development to large sph

6、erical main factors: design and manufacturing specifications, spherical steel, spherical field assembly and welding problems, spherical tanks on-site heat treatment, dimensional accuracy of shell plates. Therefore, the structure of spherical tank and material selection were proposed new requirements. This paper corresponding improves on the pillar of the main connection for the spherical structure, changing the U-shaped column structure type pillar into pillar oblong
