浮头式换热器设计1zodvh.doc

AOS60?0型换热器?的机械设计?摘 要 本设计说明?书是关于A?OS600?型换热器的?设计，主要是进行?了换热器的?工艺计算、换热器的结?构和强度设?计。设计的前半?部分是工艺?计算部分，主要是根据?给定的设计?条件估算换?热面积，从而进行换?热器的选型?，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。设计的后半?部分则是关?于结构和强?度的设计，主要是根据?已经 选定的换热?器型式进行?设备内各零?部件（如接管、折流板、定距管、钩圈、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、管板厚度的?计算、浮头盖和浮?头法兰厚度?的计算、开孔补强计?算等。最后设计结?果可通过6?张图表现出?来。关于浮头式?换热器设计?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， 浮头式换热?器 ，管板 ，浮头盖 ，浮头法兰AOS60?0 Excha?nger Desig?nAbstr?act The desig?n manua?l is about? the AOS60?0 float?ing head heat excha?nger, which? inclu?ded techn?ology? calcu?late of heat excha?nger, the struc?ture and inten?sity of heat excha?nger. The first? part of desig?n is the techn?ology? calcu?latio?n proce?ss. Mainl?y, the proce?ss of techn?ology? calcu?late is accor?ding to the given? desig?n condi?tions? to estim?ate the heat excha?nger area, and then, selec?t a suita?ble heat excha?nger to check? heat trans?fer coeff?icien?t just for the actua?l heat trans?fer area .Meanw?hile the proce?ss above? still? inclu?de the press?ure drop and wall tempe?ratur?e calcu?latio?n . The secon?d half of the desig?n is about? the struc?ture and inten?sity of the desig?n. This part is just on the selec?ted type of heat excha?nger to desig?n the heat excha?ngers? compo?nents? and parts? ,such as vesti?ng baffl?ed plate?s, the dista?nce contr?ol tube, circl?e hook, tube boxes?. This part of desig?n mainl?y inclu?de：the choic?e of mater?ials ident?ify speci?fic size, ident?ify speci?fic locat?ion, the thick?ness calcu?latio?n of tube sheet?, the thick?ness calcu?latio?n of float?ing head plant?ing and float?ing head large?, the openi?ng reinf?orcem?ent calcu?latio?n etc. In the end, the final? desig?n resul?ts throu?gh six maps to displ?ay. The each aspec?ts of the float?ing head heat excha?nge has detai?led instr?uctio?ns in the desig?n manua?l. Key word: Shell?-Tube heat excha?nger, float?ing head heat excha?nger, tube sheet?, float?ing head plant?ing, float?ing head flang?e. 目录 TOC \o 1
