The design task is mainly according to the known conditions to choose the design of fixed tube plate heat exchanger, the advantages of fixed tube plate heat exchanger is forging used less, low cost; heat transfer area ratio of floating head type for heat exchanger is 20% to 30% and a bypass flow small.</p><p>The heat exchanger is mainly completed is between water vapor and water heat exchange, first of all according to the given design temperature and pressure to determine structure of equipment and the shell side and tube side material, and then according to the nature of the material and the heat transfer area to determine the heat exchange tube materials, dimensions, number of roots. And design pressure for tube side 2.31MPa, shell 0.935MPa, the working temperature of the tube process 50 DEG C, 130 DEG C shell, design temperature tube process at a temperature of 80 DEG C, shell and 140 DEG C, heat transfer area for 256m2. The phi 25 x 2.5 x 3000 seamless steel pipe heat exchanger can be calculated 622 heat exchange tube, D=1200mm cylindrical root according to determine the root number of heat exchange tube heat exchanger tube arrangement and according to the arrangement and length of heat exchange tube to determine cylinder diameter and baffle the choice. Determine the thickness of the shell and the head and carry out the intensity verification by calculating the inner diameter and the internal pressure of the container. Then the strength design of components of the various components of the heat exchanger, flange design, selection and calculation and checking, hook and loop and floating head flange design calculation and checking of the pipe and pull off force calculation. Also includes a tube plate structure design, anti scour baffle, slideway structure design and the design of support. The standard parts in the structure design can be selected directly according to the national standards; the non standard parts must be checked for the corresponding stress after the design of the structure.</p><p>Tube plate and tube heat exchanger and the connection mode of welding, tube plate more stress, and the temperature inside and outside have certain difference. Therefore, on the tube sheet strength check is a key and a difficulties.</p><p>Keywords: &nbsp;heat exchanger； &nbsp;strength design； &nbsp;structure design</p><p>目 &nbsp;錄</p><p>第一章傳統(tǒng)工藝計算<span
