In the present invention, since the gas-liquid contact portion is horizontal, the gas velocity at the gas-liquid contact portion is about three times faster than that of the conventional device. However, by appropriately setting the factors that affect the desulfurization rate, that is, the liquid-gas ratio, the absorption liquid pH, the inlet SO 2 concentration, the particle size of the absorbent, the type of spray nozzle, etc., the absorption performance is greatly affected. That is, securing of gas-liquid contact surface (miniaturization of droplets, liquid-gas ratio), securing of propulsive force for absorption (selection of optimum operating pH, retention of circulating liquid), uniform gas-liquid distribution It is possible to secure the same properties as in the conventional gas absorption tower, and thus to obtain the desulfurization performance equivalent to that of the conventional gas absorption tower.

In summary, in the present invention, since the gas absorption tower 1 is horizontal and the exhaust gas 10 is introduced from the left inlet 1a and discharged from the right outlet 1b, the spray pipe generated in the conventional vertically long gas absorption tower is used. A large space with the circulation tank can be omitted, and as a result, the capacity of the gas absorption tower can be reduced to about 30%. That is, the device can be downsized and the cost can be reduced.

Further, since the baffle plates 6 are provided in the upper and lower stages in the middle of the parallel flow side spray pipe 4a and the counter flow side spray pipe 4b, the distance between the spray pipe 4 and the circulation tank 2 is short. Nevertheless, the concentration of the absorbent slurry 11 below is prevented, and the gas-liquid contact effect between the exhaust gas 10 and the absorbent slurry 11 is enhanced. Furthermore, the baffle plate 6
Is installed in a state slightly inclined from the horizontal, the absorbent slurry 11 flows down quickly without staying on the baffle plate 6, and the circulation of the absorbent slurry 11 is promoted. Therefore, the desulfurization rate equivalent to the conventional one can be achieved despite the downsizing of the device.

Further, since the baffle plate is installed in a state slightly inclined from the horizontal, the absorbent slurry flows down quickly without staying on the baffle plate, and a gas-liquid contact effect can be expected in this part as well.
