摘要：石油化工装置工艺设计中，对多余或紧急排放的可燃气体（如氢气、天然气等）集中焚烧排放是常见的工艺操作，但处于流程末端的高架放空火炬，往往因高度过高，成为工程安装施工、检修、维护的难点。其中，高架火炬火炬头的更换因施工难度大，风险高往往往成为装置停工大修的控制工程。 本文从火炬头更换吊装的吊装工艺设计；吊桅杆、缆绳、抱杆卷扬机、滑车组、钢丝绳的受力情况的核算，对火炬头吊装过程的风险进行全面控制，达到了安全、平稳吊装的目的，顺利的完成了火炬头的更换。

Abstract: In the process design of petrochemical plants, it is a common practice to centrally incinerate and discharge excess or emergency emissions of combustible gases (such as hydrogen, natural gas, etc.). However, the elevated flare at the end of the process often poses difficulties for engineering installation, construction, maintenance, and repair due to its high height. Among these, the replacement of the flare head of the elevated flare often becomes a control engineering task for plant shutdown and overhaul due to the high construction difficulty and risk.This article comprehensively controls the risks of the torch head lifting process through the design of the lifting process for replacing and lifting the torch head, as well as the calculation of the stress conditions of the lifting mast, cables, holding pole winch, pulley block, and steel wire rope, achieving the goal of safe and smooth lifting and successfully completing the replacement of the torch head.
Keywords : lifting；process design；stress calculation；smooth lifting
