Inventor: OKAZAWA KOICHIRO
IPC: B01D3/32
Filed: 2004-02-13
Abstract: <P>PROBLEM TO BE SOLVED: To evenly disperse a liquid and heighten the separation efficiency of a distillation tower.  <P>SOLUTION: The liquid dispersion apparatus comprises a plurality of distribution grooves arranged in parallel to one another and each composed of a bottom wall, side walls, and end walls 69 and having an opened upper end and liquid walls 58 arranged in parallel to the side walls adjacently to the respective distribution grooves. A plurality of overflowing bars are formed on the upper rims of the side walls. In this case, since the liquid walls 58 are arranged adjacently to the respective distribution grooves and a plurality of overflowing bars are formed on the upper rims of the side walls of the distribution grooves, a liquid in the distribution grooves overflows at the overflowing bars and is thus dispersed. Accordingly, even if a liquid having a clogging property or a liquid containing a mixture of a clogging material, a pollutant, or the like is used, the overflowing bars are not clogged and the liquid can be dispersed evenly.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
