| 摘 要： | 网波填料是一种新型、高效的规则填料。使用双层不锈钢网具有良好的可润湿性和整个填料表面均匀的液体分布,因而即使对于像水之类表面张力大的液体,在低的液体负荷下,分离效率也能显著增加。 在内径10cm的塔,填料高度200cm和塔顶压力约125Torr的情况下,进行了D_2O/H_2O体系真空精馏试验。本文使用测得的数据,获得了该填料压力降和传质的良好关联。

| Abstract: | This packing is a new, high efficiency and regular packing. The use of two layers of stainless steel gauze gives good wettability and uniform liquid distribution over the entire packing surface, so that the separation efficiency is increased sensibly even with liquids of high surface tension like water and under low liquid load.Vacuum rectification tests on D2O/H2O system have been performed with a column of 10cm inside diameter, the packing hight of 200cm, and column top pressure about 125 torr. By the use of the measured data, satifactory correlations for pressure drop and mass transfer of this packing were obtained in the article. |
