摘要

立式热虹吸再沸器内的流动不稳定性是一个严重问题.本文作者最近研制的内热虹吸再沸器能够解决上述问题.采用相同几何尺寸的石英管及铜管进行实验

前者有利于观察研究

后者则能提供更多的定量结果.工作介质为水、硫酸、三乙醇胺重油、乙醇-水、甲醇-乙醇、乙醇-丙醇及其他一些混合物.在观察水在管内的流动特性试验中

用聚丙烯颗粒作为示踪粒子

其密度与水非常相近.研究的内容包括循环速率、流型、传热速率及结垢等问题.提出了一个流动模型及设计方法.计算结果可用来推算此沸腾设备内的两相流及传热特性.

Abstract

Vertical thermosyphon reboilers sufferd seriously from being unstable. The problem can be solved by a newly developed internal thermosyphon re-boiler. Experiments were carried out in both quartz and copper tubes of similar geometrical dimensions. The former allowed better visual observation and the latter gave more quantitative informations. Water

sulfuric acid

tri-ethanolamine

heavy oil

ethanol-water

methanol-ethanol

ethanol-propanoland other mixtures were used as working media. Particles of polypropene

with densities approaching that of water were used as tracer in the water system for the investigation of the flow characteristics. Rate of circularion

flow patterns

rate of heat transfer and fouling were studied. A flow model and a design approach were proposed. Calculated results could be used to predict the characteristics of a two-phase flow and its heat transfer within the reboiler.
