聚合反应釜的结构设计 摘要 目前，随着我国工业的快速发展，各行各业对压力容器的使用越来越广泛，涉及的领域包括化工、橡胶、食品、医药、石油等方面，尤其是我国对橡胶产品的需求量越来越大，聚合反应釜是橡胶生产过程必不可少的反应容器，现在国内主要的反应釜的容积为30m生产效率低，成本高，已经不能满足橡胶生产需求，更大容积的反应釜的设计刻不容缓。 故本次设计的反应釜容积为60m，实现了大容积化设备，提高了其生产效率，釜内的反应温度为150℃，采用从底部进行通入蒸汽进行加热，采用蒸汽加热能使釜内受热均匀，使物料受热更均匀，反应更彻底，相比之前夹套加热传热效率更高。本次设计为反应釜釜体的设计，搅拌装置的选型与尺寸设计（其中搅拌叶选用的是平直桨叶，直叶桨搅拌速度相对于其他搅拌桨速度快，搅拌效率高），人孔的开孔及补强计算，传动装置，反应釜的轴封装置选用，支座的选型，选用焊接类型，同时绘制了零件图、反应釜釜体体图以及反应釜的装配图等。设计方法采用压力容器常规设计的方法，遵循《化工设备》要求，按照GB150-98《钢制压力容器》等技术法规执行。 关键词：压力容器；搅拌器；聚合反应釜 ABSTRACT At prese
