| 摘 要： | 提出一种适合污泥处理过程中的余热回收的新型隔板管壳换热器,并与同样规格的普通管壳换热器性能进行对比。建立了简化的壳程计算模型,应用FLUENT计算软件分别对普通管壳换热器和新型隔流板式换热器进行数值模拟,获得了2种热交换壳程内部的流动分布、温度分布和压力分布,并将模拟结果和试验数据进行对比。试验及模拟结果表明,新型隔板式换热器温度分布均匀、流动死区少、传热效率高,综合性能远高于普通管壳换热器。

| Abstract: | A new type of shell and tube heat exchanger was designed for heat recovery in sludge treatment process，compared
with performance of a conventional shell and tube heat exchanger of the same specification． A simplified calculation model of
shell and tube heat exchanger was set up，and FLUENT software was used to simulate the common shell heat exchanger and
the new type heat exchanger，the flow distribution，the distribution of temperature and pressure inside the shell of the two heat
exchangers were got，the simulation result was compared with the experimental data． The experimental and simulated results
showed that new plate type heat exchanger has even temperature distribution，less flow dead zones，high heat transfer
efficiency，and its comprehensive performance was far higher than that of ordinary shell and tube heat exchanger． |
