2、径为mmmm5.225的碳素钢管、确定使用传热管总计 228 根 和壳体内径为 600mm。然后进行换热器核算，最终验证了传热系数、有效平均温差 39.09、流体流动阻力、面积裕度 19.0%和压降等都在合理范围内。通过计算可得出本 设计的正确性后，进行筒体、管箱、管板、法兰、折流板及其它设备进行计算和选型， 并进行必要的校核。最后运用 CAD 制图软件进行装配图和工艺流程图的绘制。 关键词：关键词：固定管板式；面积裕度；压降 银川能源学院化工原理课程设计说明书 Abstract This topic is the design of the handling capacity of 1510
3、4 t/a of kerosene cooler, kerosene entrance temperature of 140 degrees centigrade, the outlet temperature is 40 degrees centigrade; cooling water entrance temperature of 30 degrees centigrade, the outlet temperature is 40 degree Celsius. Two fluid temperature difference, to achieve energy-saving hea
4、t transfer between the materials. So the selection of the fixed tube plate heat exchanger. And the double, single shell and kerosene go shell cooling water, go pipe heat exchanger process. This design to determine the design scheme and material data, by estimating the heat transfer area to calculate
5、 process structure size, choose diameter of carbon steel , determined using the heat transfer tube of a total of 228 root and the inside diameter of the shell is 600 mm. and heat exchanger calculation, the final validation of the effective heat transfer coefficient, average temperature of 39.09 degr
6、ees centigrade, fluid flow resistance, area 19% margin and pressure drop are within a reasonable range can be obtained by calculation. The correctness of the design, for the cylinder, tube box, tube plate, baffle and flange. Other equipment calculation and selection, and carry out the necessary verification. Finally using CAD drawing software drawing assembly drawings and process flow chart. Keywords:Fixed tube plate; area margin; pressure drop 银川能源学院化工原理课程设计说明书
