【摘要】 在直径为８０ｍｍ的有机玻璃塔内，以水空气为介质，对２５ｍｍ聚丙烯鲍尔环填料流体力学性能进行研究。找出了填料层压降和空塔气速的变化关系，泛点气速和喷淋密度的关系。根据实验数据关联出湿填料因子、泛点填料因子和喷淋密度的经验式，其计算值与实际值的最大误差分别为１１％和１２．８％。更多还原

【Abstract】 The fluid mechanic properties of 25 polypropylene Pall ring is studied with air and water as the medium in an organic glass tower with a diameter of 80 mm. Relationships of pressure drop across the packing zone with the apparent velocity and flooding volocity with spraying density are obtained. And finally an empirical equation including wetted packing factor and flooding packing factor and spraying density is got from the exprimental data. 更多还原
