The partition is provided with a large number of sparger pipes so that the sparger pipes reach inside an absorbing liquid stored in the absorbing liquid storage portion. The partition is provided with a single gas riser in communication with a space upper than the absorbing liquid in the absorbing liquid storage portion. An upper end of the gas riser passes through a top plate portion of the sealed vessel and protrudes upward.

Exhaust gas treatment apparatus

The exhaust gas treatment apparatus has a sealed vessel which is vertically partitioned into two spaces by a partition. The partition is provided with a gas riser for deriving treated exhaust gas from an upper space of the absorbing liquid storage portion. A large number of sparger pipes are provided in a effective region, so as to reach inside an absorbing liquid stored in the absorbing liquid storage portion. A non-jet region is provided in the effective region. The froth layer is not formed in the non-jet region, and the absorbing liquid in a foamed state flows down from the froth layer therearound to circulate the absorbing liquid.
