摘要: 法兰连接结构火炬塔架安装一般采用散件组装或分节吊装,由于施工条件苛刻本文提出一种法兰连接式火炬塔架一次性整体吊装技术方法的创新。使用CATIA有限元分析模拟火炬塔架整体吊装时的水平和竖直两个极限状态工况受力,对吊装时塔架的强度和稳定性进行校核计算,查找出危险点及提出薄弱结构的加固处理措施,为吊装工艺设计提供依据。

Abstract: Knocked down assembly or segmentation hoisting is generally used for flare stack with flange connection structure. This paper presents a novel technology of integral hoisting of flare stack with flange connection structure. In the paper, CATIA finite-element-analysis is used to build the model of flare stack and to simulate working condition in both horizontal and vertical limit states during integral hoisting of flare stack. The strength and stability of flare stack during hoisting is checked and calculated. The dangerous points and weak structures are conducted through the reinforcement treatment to provide evidence for hoisting procedure design and formulation of hoisting plan.
