石化反应器吊装方法与技术

Hoisting Methods of Petrochemical Reactor

通过对几个不同质量的反应器采用不同吊装设备吊装的实例,总结出反应器吊装时使用的不同器具、不同吊装方法与技术。文章阐述了单桅杆吊装甲醇合成反应器、双桅杆吊装加氢裂化反应器的方法;介绍了单吊车作主吊的"吊车抬吊法"、双吊车作主吊的"吊车滑移法"吊装反应器的方法;同时也介绍了其他的吊装方法,如环梁吊等;还对采用顶板式吊耳和力矩分配器进行起吊,而用双机作主吊的吊车的安全余度进行了探讨。

In terms of several hoisting cases in which the reactors have different masses and the different equipment is used for the hoisting operations, this paper summarizes reactor hoisting methods. It illustrates the method using single mast to hoist methanol synthesis reactor and dual masts to hoist hydrocracking reactor, the uplifting-hoisting method using single crane as a master crane and the slipping method using dual cranes as master cranes, and other methods such as using ring beam. The paper also discusses the crane safety margin when dual cranes used as master cranes together with top-board type liftinglug and moment distributor.
