Exhaust gas treatment apparatus

An exhaust gas treatment apparatus, comprising:

• a sealed vessel in which exhaust gas is introduced and treated;
• a partition which vertically divides an inside of the sealed vessel;
• an absorbing liquid storage portion which is provided under the partition of the sealed vessel and stores an absorbing liquid for desulfurization absorbing sulfur oxides from exhaust gas;
• an exhaust gas introducing portion which is provided above the partition of the sealed vessel and introduces exhaust gas from outside of the sealed vessel;
• a plurality of sparger pipes which are in communication with the exhaust gas introducing portion, extends inside the absorbing liquid stored in the absorbing liquid storage portion on the lower side from the partition, and ejects and disperses exhaust gas into the absorbing liquid from the exhaust gas introducing portion;
• and
• a gas riser which is in communication with a space above the absorbing liquid in the absorbing liquid storage portion, extends upward from the partition, and passes through the exhaust gas introducing portion,
• wherein the gas riser is provided to extend to the outside of the sealed vessel above the exhaust gas introducing portion, and treated exhaust gas is derived outside the sealed vessel by the gas riser,
• wherein a ratio of a vertical length of an upper space of the absorbing liquid storage portion to a diameter of the sealed vessel is 0.05 to 0.2,
• wherein a ratio of a cross-sectional area of the gas riser to a cross-sectional area of the sealed vessel is 0.15 to 0.40, and
• wherein a ratio of a vertical length of the gas riser to a diameter of the gas riser is 0.3 to 0.1.
