冷凝器设计说明书.doc

本科毕业设计 PAGE PAGE III 摘要 根据设计条件，依据GB151和GB150及相关规范，对卧式壳程冷凝器进行了工艺计算，结构计算和强度计算。 工艺计算部分主要是根据给定的设计条件估算换热面积，从而进行冷凝器的选型，校核传热系数，计算出实际的换热面积，最后进行压力降和壁温的计算。结构和强度的设计主要是根据已经选定的冷凝器型式进行设备内各零部件（如接管、折流板、定距管、管箱等）的设计，包括：材料的选择、具体尺寸确定、确定具体位置、管板的计算、法兰的计算、开孔补强计算等。最后设计结果再通过装配图零件图等表现出来。 关于卧式壳程冷凝器设计的各个环节，设计说明书中都有详细的说明。 关键词：管壳式换热器 卧式壳程冷凝器 管板 法兰 Abstract According to the design condition, GB151 and GB150 and related norms, design a horizontal shell condenser, which included technology calculate of condenser, the structure and intensity of condenser. The technology calculation process. Mainly, the process of technology calculate is according to the given design conditions to estimate the heat exchanger area, and then, select a suitable condenser to check heat transfer coefficient ,just for the actual heat transfer area .Meanwhile the process above still include the pressure drop and wall temperature calculation . The design is about the structure and intensity of the design. This part is just on the selected type of condenser to design the condenser’s components and parts ,such as vesting ,baffled plates, the distance control tube, tube boxes. This part of design mainly include：the choice of materials，identify specific size, identify specific location, the thickness calculation of tube sheet, the thickness calculation of flange, the opening reinforcement calculation etc. In the end, the final design results through HYPERLINK app:ds:assemblyassembly HYPERLINK app:ds:drawingdrawing and parts drawing to display. The each aspects of the horizontal shell condenser has detailed instructions in the design manual. Key word: Shell-Tube heat exchanger; Horizontal shell condenser; Tube sheet; Flange. 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc29603 摘要 PAGEREF _Toc29603 I HYPERLINK \l _Toc13412 Abstract PAGEREF _Toc13412 II HYPERLINK \l _Toc13637 第1章 绪论 PAGEREF _Toc13637 1 HYPERLINK \l _Toc3621 1.1 冷凝器概述 PAGEREF _Toc3621 1 HYPERLINK \l _Toc16943 1.2 冷凝器类型 PAGEREF _Toc16943 1 HYPERLINK \l
