<p>Disclosed is an exhaust gas treatment apparatus which has a simplified structure that allows manufacturing costs to be reduced and makes maintenance easier. The exhaust gas treatment apparatus has a sealed vessel (21). The sealed vessel (21) is partitioned vertically by a partition (22) into two spaces. The space below the partition (22) serves as an absorbent liquid storage unit (24), and the space above the partition (22) serves as an exhaust gas introduction unit (26). A plurality of sparger pipes (29) are disposed upon the partition (22) to be inserted into the absorbent liquid stored in the absorbent liquid storage unit (24). A gas riser (30) is disposed upon the partition (22) to communicate with the space above the absorbent liquid in the absorbent liquid storage unit (24). The top end of the gas riser (30) protrudes through the top plate portion (32) of the sealed vessel (21). The introduced exhaust gas is ejected from the exhaust gas introduction unit (26) through the sparger pipes (29) into the absorbent liquid and is discharged thereafter through the gas riser (30) and out of the sealed vessel (21).</p>
