CCD法测量精馏设备中气泡尺寸分布

The measurement of bubble size distribution by CCD method

气泡的尺寸及其分布是精馏操作、精馏设备设计的重要参数。因此精确的测量气泡的尺寸是每一个研究者所追求的目标。为此人们开发出多种测量气泡尺寸的方法。这些方法各有其优缺点以及适用范围。对主要的气泡尺寸的测量方法进行了总结,并应用CCD法对精馏塔中的气泡尺寸分布进行了测量。

The bubble size and bubble size distribution are the key parameter of distillation operation and design of e-quipment of distillation. Therefore, the accurate measurement is the every researcher s target. Up to now people develop a lot of methods to measure the bubble size. Those methods have various advantages and disadvantages. In this paper all kind of measurement methods are summarized, and the CCD method is applied to measure the bubble size distribution on a tray of the distillation tower.
