Abstract

The scarcity of freshwater is one of the biggest issues in the world, as a result of which more attention is given to the thermal distillation process for seawater and as well as brackish water distillation which removes almost all types of contaminants. Distillation is a phase change process in which steam is used as a heat source for evaporating the feed water. Multiple-effect distillation makes the process economical by recycling the latent heat of vaporization. In this paper, the vertical tube evaporator (VTE) design and modeled for MED for estimating the overall heat transfer coefficient by using the developed correlations of the Bell method, Kandlikar, and Kutateladze and compared its previous work in literature. The result shows good agreement with previous work and reliability in design. The developed model can be used to design the VTE for estimating the dimension for large-scale to micro-scale MED plant.
热驱动多效蒸馏系统中垂直管式蒸发器的设计与建模
淡水短缺是世界上最大的问题之一,因此人们越来越关注海水的热蒸馏过程,以及去除几乎所有类型污染物的微咸水蒸馏。蒸馏是一种相变过程,其中蒸汽被用作热源来蒸发给水。多效蒸馏通过回收汽化潜热,使蒸馏过程经济。本文采用Bell方法、Kandlikar方法和Kutateladze方法建立了垂直管式蒸发器(VTE)的总体传热系数估算模型,并比较了前人的研究成果。计算结果与前人的工作结果吻合良好,设计可靠。所建立的模型可用于大型到微型MED装置尺寸估计的VTE设计。
