【摘要】 根据金属板波填料的结构,建立其液流分布模型.在φ500mm和φ200mm塔内,实测了6.3型和4.5型不锈钢板波填料的液流分布.结果表明:模型值与实测值基本相符.对不同填料在相同条件下的实测证明:金属板波填料的液流分布性能,优于拉西环、鲍尔环和阶梯环.文中就气液负荷和喷淋装置等因素的影响作了讨论,并提出了分布器喷淋点密度的推荐范围.更多还原

【Abstract】 A liquid distribution model based on packing structure was developed for metallic corrugated plate packings. The model was verified by experimental results obtained in a 200mm-diameter and a 500mm-diameter column packed with type-4.5 or type-6.3 stainless steel corrugated plate packings.Further investigation showed that metallic corrugated plate packings are superior in liquid distribution behavior to Raschig rings, Pall rings and Cascade rings. From experimental measurements, the density of available wetting points is proposed for liquid distributor design.更多还原
