摘要： The present invention discloses an efficient mass-transfer separation bulk filler structure, which includes a bulk filler body with closely-fit multilayer structures, wherein an annular wall surface of the bulk, filler body has a corrugated angle group. A lower portion of the bulk filler body is of a bell-mouth shape. Three passages with a same sectional area are formed inside the bulk filler body. The present invention has the characteristics of small pressure drop, large specific surface area, low liquid holdup and large void ratio. The annular wall surface is provided with the corrugated angle group to increase the disturbance and reduce a double-membrane thickness of vapor and liquid phase mass-transfer resistance, thereby improving the mass-transfer coefficient and separation efficiency. Meanwhile, by adopting the bell-mouth shape, the stability and natural stacking regularity of the bulk filler can be improved.
