氨冷却器

艾草精油提取设备卡环弯制

摘要

本设计说明书是关于浮头式换热器蒸氨冷却器的结构设计与优化的设计。浮头式换热器是管壳式换热器系列中的一种，由于管束的膨胀不受壳体的约束，因此不会因管束之间的差胀而产生温差应力，另外浮头式换热器的优点还在于拆卸方便，易清洗。在化工工业中应用广泛。按照设计要求，设计的前半部分主要是根据给定的换热面积，从而选择换热管的规格和长度，进而计算筒体直径。后半部分主要是结构和强度设计。主要根据已选定的换热器形式进行设备内各零部件的设计，包括筒体、封头、换热管及管板强度设计、温差应力计算及校核、设置膨胀节计算及选型、开孔补强设计计算等。

Abstract

光学增强器守卫 The design specification is about handling hypoxia heat exchanger cooler ammonia evaporation of structural design and optimization design. Handling hypoxia heat exchanger tube heat exchanger is one of the series, due to the expansion of the vascular bundles from the constraints of the shell is, therefore, not for over the difference between from bilge temperature distribution, and the advantages of handling hypoxia heat exchanger is also remove the convenient, easy to clean. In the chemical industry is used widely. According to the design requirements, design of the first half is mainly according to the given heat transfer area, and select the specifications and the length of heat exchange tube, and then calculating tank diameter. Half of the main structure and strength design is. Mainly based on the selected heat exchanger form within the equipment parts design, including the cylinder body, the head of heat exchange tube and tube plate,
