摘要

以荧色物作标记微粒是微粒技术研究中的一项新方法.荧色物具有很高的分析灵敏度

用通常的荧光光度比色仪

可将其浓度测至1×10~(-10)g/ml;若采用Bergund-Liu气溶胶发生器

就可以得到已知直径及浓度的荧光性标准微粒

这对于研究微粒的空气动力学行为以及对于处理微粒状物料设备的标定是十分有效的.本文介绍了单分散气溶胶发生器

通过实验得出了使用荧光性微粒的一些重要条件

其中包括;溶剂的选择、微粒的发生与捕集、微粒中荧色物的提取及分析.文中还比较了两种常用的荧色物(荧光素钠及若丹明B)用于微粒技术的可能性

并应用这一技术对一种轴流式旋风分离器作了研究

得到了微粒在分离器各部位沉积情况的数据

它表明

该旋风分离器的分高效率和Stokes数间有一定的函数关系.

Abstract

This paper describes the generation of monodisperse fluorescence aerosols for instrument calibration study. Important considerations in the use of these aerosols are discussed. These include solution preparation

monodisperse aerosol generation

material extraction and analysis. A comparison of two commonly used materials

i. e.

uranine (sodium salt of fluorescein) and Rbodamine B was made. It was found that uranine is most suitable to be used because of its higher detection sensitivity and higher solubility in the solvent. The use of these aerosols in the wind tunnel and laminar flow dust chamber have been described. The technique has been applied to the evaluation of a new type of an axial cyclone. Detailed information concerning particle precipitation in the cyclone is given. It was found that the collection efficiency of the cyclone is a function of the Stokes number.
