摘要： Provided is an exhaust gas treating tower in which exhaust gas flow velocity is increased more than a prior art case so that exhaust gas treating efficiency can be enhanced or the exhaust gas treating tower can be made compact if equivalent performance is to be maintained. Also, an exhaust gas treating tower ensuring a liquid recovery is provided. In an exhaust gas treating tower 10A, liquid columns C are generated and also a liquid drop generating member 20 is provided to thereby generate liquid drops M therearound to be floated. Also, liquid is spouted from spray nozzles to thereby generate liquid films F in area different from the liquid columns C. In an exhaust gas treating tower 110, a liquid drop eliminator 120 is provided upstream of a mist eliminator 118. Interval P1 of collecting plates 121 of the liquid drop eliminator 120 is made larger than interval P2 of collecting plates 119 of the mist eliminator 118. Thereby, liquid drops having larger particle diameter contained in the exhaust gas are collected by the liquid drop eliminator 120.
