摘要

目的　研究垂直列管加热的搅拌槽中温度场分布 .方法　在对称装有 4组垂直加热列管、直径为5 0 0 mm的搅拌槽中使用带副叶的 CBY桨进行搅拌

工作物料是纯度为 99.5 %的甘油

液晶粒子均匀分散在其中

采用 LC测温技术测量搅拌槽内温度场的分布 .结果与结论　在流体雷诺数较低情况下搅拌槽中的温度分布不太均匀

在列管附近存在高温区

Abstract

Aim\ To research the temperature distribution in an agitated tank which is heated by vertical pipes. Methods\ There are four sets of vertical heating pipes equipped symmetrically in an agitated tank whose diameter is 500 mm. The working liquid is glycerine whose purity is 99.5%. The LC technique was used to measure the temperature distributions in the tank. Thed liquid crystal particals are dispersed uniformly in it. Results and Conclusion\ The temperature distributions in the tank is not uniform when the Reynolds number of the impeller is low

and there exist high temperature field near the vertical pipes.
