1、经物料衡算后两流体的操作参数情况如下： 热物流釜液进口温度64.6℃，出口温度40℃；质量流量为511kg/h，进口压力为1bar，可允许压降0.35bar。 冷物流原料进口温度32℃，出口温度40℃；进口压力1bar；可允许压降为0.35bar。 2、打开Exchanger Design and Rating User Interface软件进行design（设计）。按照上面模拟结果输入参数： 图1 参数输入 3、把Aspen 模拟的冷热物流的信息导入该软件中 图2 热物流的导入 图3 冷物流的导入 根据《换热器设计手册》初步输入换热器的设计参数，对换热器进行初步设计。 图4 换热器参数输入 5、参数全部输入完毕后，通过运行软件得到换热器初步设计结果： 根据design（设计）的结果，进行rating（核算），重新对换热器的设计参数进行调整输入（根据换热器标准，选择合适的公称直径与长度，调整板间距等），其输入方法与design（设计）的输入基本相同在此不再演示。然后运行rating软件得到换热器设计结果。然后根据警告合理调整，直到符合设计标准。核算压降：壳程压降为0.327ba, 管程压降为0.0121ba。核算裕度：裕度为24%。符合设计标准。其核算报告如下： 1.6 high vocational designed manufacturing class national career qualification education training programme--car detection and maintenance technology professional teaching plans a, and training target and training specifications car detection and maintenance technology professional training oriented car Hou market of car maintenance, and car sales and after-sales service integration enterprise, and and and car using and maintenance about of career field of production, and service, and management line post, training support party of line, adapted car maintenance, and car using front line need, de, and wisdom, and body, and beauty full development, Has good all-around professional ability, knowledge of professional theoretical knowledge and good practice, can successfully enter car market employment, through vocational training, continuing education, self-taught, to continue learning channels to achieve all-round development in all aspects of vehicle inspection and maintenance technology of high quality workers.
