装置の吸収塔。It has a liquid storage tank for storing an absorption liquid in which an absorbent containing calcium carbonate is dissolved, and while circulating the absorption liquid in the tank, the circulating absorption liquid and exhaust gas from combustion equipment such as a boiler are subjected to a contact reaction. In an absorption tower of a flue gas desulfurization device for desulfurizing flue gas, a rotating body having gas entrainment blades is provided in the liquid storage tank to mix the gas in the tower into the absorption liquid and aerate it. An absorption tower for a flue gas desulfurization device, characterized in that it is configured to increase the solubility of the absorbent.
