| 摘 要： | 文章根据双膜理论,分析了气液反应的吸收机理,用图像边界识别法测量亚硫酸盐强制氧化气液反应速率。在测量氧化速率时,让单个氧气泡在亚硫酸钠溶液中反应,用数码相机拍下氧气泡由于反应而不断缩小的照片,用图像处理程序进行分析、识别,最后计算得出氧化速率。实验结果与理论分析结果相同,证明了该方法的正确性及其可以作为气液传质理论研究的测量方法。

| Abstract: | In the present work, we used the two-film theory to analyze the sulfite forced oxidation reaction and the oxidation rate was experimentally studied by contacting pure oxygen with a sodium sulfite solution. The sole oxygen bubble in sulfite solution was observed by a CCD camera when measuring the reaction rate of sulfite oxidation, and the graphic pictures were captured. The experiment results and the theory results get the same conclusion, and the method is suitable for the research of gas-liquid mass transfer theory. |
