摘要
换热器是一种十分重要的节能设备,能够大幅提高能源使用效率,广泛应用于石油、化工、动力、冶金等各个领域,在国民经济生产中占据着特别重要的位置,尤其是在走可持续发展路线的今天,节能环保成为工业发展的一个主旋律。换热器在缓解能源紧缺的应用中显得尤为重要,国内外各研究机构、高等院校对换热器的研究一直非常重视。
根据任务书要求,本设计设计对象为F280填料函式换热器,主要为换热器的工艺计算、换热器的结构以及强度的设计。此次设计的主要过程分三个部分,一是工艺计算部分,主要是由给定的换热面积以及其他参数,进行换热器的选型、校核传热系数、计算出所需要的管壳程的各部分结构,并初步选定结构的各部分参数,如材料尺寸等;第二部分是关于结构以及强度的设计校核,主要是对选定的各部件的设计进行应力计算;第三部分是对换热器的制造安装,防腐以及后期的维护保养做出说明。
经过反复的修改结构设计参数,以及图纸的绘画,完成了填料函式换热器的设计。
关键词:填料函强度焊接防腐
