板壳式降膜蒸发器结构及性能研究

The Study on Structure and Characteristics of the Shell plate Falling Film Evaporator

结合板壳式换热器和板式蒸发器的结构特点，在高效水平管喷淋式降膜蒸发器的基础上，开发一种新型板壳式降膜蒸发器，理论分析和实验结果均表明，以椭圆腔板束为蒸发内件的新型蒸发器，蒸发速度快，传热效率高。

In this paper,based on efficient horizontal circular tube spray falling film evaporator,a new kind of shell plate falling film evaporator has been developed,which has combined with the structural characteristics of the shell plate heat cxchanger and the plate type evaporator.Theoretical analysis and experimental results show that the evaporator which owned the Elliptical Cavity Plate Bundle (Abbr.:ECPB)as the evaporating component has faster evaporating speed and higher heat transfer efficiency.
