摘要

雾化技术在能源、化工等领域应用广泛，研究雾化机理和优化雾化喷嘴性能的前提是对其雾化液滴尺寸及粒度分布进行准确有效的测量和表征。目前常用的雾化液滴粒度测量技术，如基于光散射或衍射原理的激光粒度仪和相位多普勒分析仪等，能够较准确地测量粒径分布比较窄、最大粒度在2000 μm以下的喷雾，但对含特大颗粒且粒径分布很宽的喷雾，往往难以得到可靠结果甚至不可能进行测量。本文提出了用图像法测量这类大流量喷雾，构建了图像法测量系统，编写了图像处理程序，经标定实验后，采用该系统对某喷嘴喷雾液滴粒径分布及规律进行了测量研究。研究结果表明图像法可用于大型喷雾液滴粒度及分布的测量。

Abstract

Atomization technology is widely used in the energy and chemical industries. Accurate and effective measurement and characterization of atomized particle size and size distribution is the premise of the research on atomization mechanism and performance optimization of atomizer. At present

the frequently used techniques for measurement of atomized droplet size

for example the laser particle size analyzer and phase Doppler analyzer based on light scattering or diffraction principle

can accurately measure spray of which particle size distribution is narrow and maximum particle size is under 2000 μm. But for the measurement of a large spray whose particle size distribution is wide or which contains large droplets

it is always difficult or even impossible to obtain an accurate result. This paper used the imaging method for measurement of such large spray

developed the image measurement system

wrote the image processing program

calibrated the measurement system

and used it for the droplet size distribution measurement and investigation of a nozzle spray. The research results showed that the imaging method could be effectively used for the measurement of droplet size and distribution of a large spray.
