PACKING MATERIAL FOR SUBSTANCE AND/ OR HEAT EXCHANGING TOWER

摘要

PURPOSE:To realize diffusion and breakdown of a boundary film in two phases of liquid and gas and to enhance contact efficiency by forming grooves shaped into ruggedness having waveform on a sheetlike base material and meandering the grooves. CONSTITUTION:Grooves parts 3 shaped into a plural continuous ruggedness having a waveform are alternately extended in a transverse direction and formed on the surface of a sheetlike base material 1. In a state wherein the packing material is provided on the inside of a tower, the upper face parts 5 in the vertical direction of large parts of the groove parts 3 have an angle smaller than 140 degrees for the tower axial line 2. The respective groove parts 3 formed on the sheetlike base material 1 are mutually and vertically meandered. Thereby the diffusion of liquid in the transverse direction and the lower direction is improved. In relating to gas raised from the lower part, distribution in right and left is performed by convex projections which are formed by the meandering of grooves and directed to the lower part of the tower axis 2. The breakdown of a boundary film between liquid and gas being the trouble in the contact of liquid with gas is promoted by utilizing the disturbance of flow based thereon to enhance liquid-gas contact.
