<p>PURPOSE:To perform stirring with good efficiency by imparting flowability even in the vicinity of a tank wall, by providing a means for introducing formed gas into the gap between a partition wall and a side wall, and a means for withdrawing the digested solution in a digestion tank to recirculate the same to the bottom part of said digestion tank. CONSTITUTION:Formed gas is introduced into the partitioned space 5 confined by a partition member 1 and a side wall through a recirculation line 2 and the introduced gas rises through the partitioned space 5 as bubbles while a digested solution is flowed in the partitioned space 5 by the rising gas bubbles to generate the flow of the digested solution. The digested solution in the vicinity of the bottom part wall of a digestion tank 4 is flowed to the partition member 1 along the bottom part wall in cooperation with the recirculation action of a pump and flowed into the partitioned space 5 from the gap between the lower end of the partition member 1 and the bottom part wall to rise through said space 5. Further, the digested solution is moved to the circumferential direction of the digestion tank 4 along the side wall thereof and flowed into the partition space 5 from the gap between the side edge of the partition member 1 and the side wall of the digestion tank 4.</p> |
