大型储罐已经成为石油化工装置和储运系统的重要组成部分,而储罐的安全在很大程度上又取决于储罐的设计。由于储罐的罐底承受着来自各方巨大的压力,因此,罐底的设计是大罐设计的重要部分。本文主要从罐底结构、设计参数的选取、罐底排版方式等方面来介绍大型立式储罐罐底的设计,对大罐设计、施工和维修都有着重要的意义。 Large tanks have become an important part of petrochemical plants and storage systems, and the safety of tanks depends to a great extent on tank design. As tank bottoms are subject to tremendous pressure from all parties, the design of tank bottoms is an important part of tank design. This article mainly introduces the design of large vertical tank bottom from the aspects of tank bottom structure, design parameter selection and tank bottom typesetting, which is of great significance to the design, construction and maintenance of large tanks.
