制御する方法がある。[Problems to be solved by the invention] When the absorbent concentration in the first absorption tower 2 is high, the SO 2 absorption performance increases, but the amount of absorbent used increases,
As a result, the amount of sulfuric acid used in reaction formula () in the oxidation tower 10 increases. Conversely, if the absorbent concentration in the second liquid of the first absorption tower is low, the amount of absorbent used and the amount of sulfuric acid used will be reduced, but there is a problem that the SO 2 absorption performance will be low. Therefore, it is necessary to maintain the absorbent concentration within the first absorption tower 2 at an appropriate and constant level. In order to keep the concentration of the absorbent in the first absorption tower 2 constant, as described above, the pH of the liquid in the first absorption tower 2 is detected, and in order to keep the pH constant, from the second absorption tower 3 to the first There is a method of controlling the flow rate of the bleed liquid 6 supplied to the absorption tower 2.

硫酸９の使用量が増加して不経済となる。 However, in the above conventional method, the supply of the bleed liquid 6 to the first absorption tower 2 is
Since the pH value is controlled to be constant, the problem arises that it becomes uncontrollable due to a decrease in the activity of lime. That is, in the first absorption tower 2, there is a certain proportional relationship between the concentration of unreacted lime in the tower and the PH, but in addition to SOx, the exhaust gas 1 contains impurities such as soot dust, chlorine, and fluorine, and these impurities The concentration of lime may be lowered by reacting with lime or worsening lime dissolution.
The proportional relationship of PH collapses and becomes unbalanced. Therefore, in a system in which the first absorption tower bleed liquid 6 is supplied to the first absorption tower 2 so that the pH of the bleed liquid in the first absorption tower 2 is constant, the bleed liquid 6 is As a result, the following problems occur. Unreacted lime in the liquid entering the oxidation tower 10 increases,
The amount of sulfuric acid 9 used increases, making it uneconomical.

ある。[Means for Solving the Problems] The present invention was made in an attempt to solve the above-mentioned technical problems, and includes two absorption towers, in which exhaust gas containing SOx is guided from the first absorption tower to the second absorption tower. In addition, the absorbent slurry is led from the second absorption tower to the first absorption tower to separate SOx from the exhaust gas, and then the bleat liquid from the first absorption tower is led to the oxidation tower to which sulfuric acid is supplied to remove gypsum. In a method for supplying an absorbent to a flue gas desulfurization equipment to be extracted, a set value for the supply flow rate of sulfuric acid supplied to the oxidation tower is set for the first absorption tower, and the second absorption tower is set so that the supply flow rate of the sulfuric acid is constant. A bleed liquid is supplied to the second absorption tower, and an absorbent slurry corresponding to the total amount of calcium in the bleed liquid supplied to the first absorption tower is supplied to the second absorption tower. This relates to a method.
