| 摘 要： | 为提高喷淋室的传热传质效率,采用数值模拟方法,开展上喷式、下喷式两种立式喷淋室内水滴运动规律,及气-水热湿传递效果的对比研究。研究发现:在初参数完全相同的情况下,上喷式喷淋室中水滴的停留时间比下喷式多停留4.7 s,上喷式喷淋室中水滴从温排风中吸收的热量较下喷式高3 K,说明向上喷淋比向下喷淋的传热传质效率更高。

| Abstract: | In order to improve the effect of heat and mass transfer, studying the influence laws of heat and mass transfer effect of various factors is of great significance to improve the efficiency of heat and mass transfer of spray chamber. This paper adopted the numerical simulation method, and carried out the contrast research of the water-drop law of motion and effect of air-water heat moisture transmission in vertical spray chamber which have two kinds including the upward-spray type and the downward-spray type. The result shows that not only the water residence time, but also the heat transfer effect the upward-spray type is superior to the downward-spray type. |
