摘要

一、引言在气-液-固三相反应器的设计和应用中

反应器内各点的相合率是极为重要的参数.传统的局部相含率检测方法加射线法、电感法和摄影法都只能在特定的场合下使用

并明显存在着较大的缺陷.为此作者开发了具有单一结构的光纤微元探头

采用激光光源

并配以微计算机系统

用于测量三相流中各相的局部含率.实验证明它具有可靠、精确和高效的优点.

Abstract

A set oi apparatus was established and used to measure the local holdup of each phase of gas-liquid-solid system simultaneously. According to the equation ε=K∑Δti/T

the signal peak and peak width time can be distinguished under the applied program. The experiment is stable and reliable. The errors among repeated experiments in average holdup measurements are less than 9%.It provides a fully-new reliable method for the detection of three phase reactor.
