<p><P>PROBLEM TO BE SOLVED: To provide a wet-type gas desulfurization apparatus which prevents a drift of exhaust gas which flows in an absorption tower, prevents a decrease in desulfurization performance by exhaust-gas blowing of peripheral wall part of the absorption tower, and prevents an increase in pressure loss beyond need by flow straightening effect of spraying droplets when a gas velocity in the absorption tower is raised to miniaturize the absorption tower. <P>SOLUTION: The wet-type gas desulfurization apparatus consists of the absorption tower 4 having an absorbing liquid, for absorbing sulfur oxides in the exhaust gas, which is sprayed out from nozzles of a spray header arranged one or more stepwise in the gas-flowing direction while the exhaust gas is flowed vertically, wherein all spray nozzles 13' (are arranged at a tip part of an absorbing-liquid taking-out pipe 19 arranged in a lower part of the spray header 8) to be arranged near a wall of the absorption tower 4 are arranged over an inner peripheral side of the tower wall apart just the determined distance from the tower wall. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
