Abstract

Exhaust Gas Desulfurizer To provide a liquid-column type exhaust gas desulfurizer which realizes flexible response in which the increase of costs and work periods is suppressed to the minimum when the change of various conditions such as desulfurization performance, field control and the like are performed. In the liquid-column type exhaust gas desulfurizer performing desulfurization by allowing gas-liquid contact to generate between absorbing solution spouted from liquid column nozzles (20) and falling down inside a desulfurization tower and combustion exhaust gas rising from a lower part of the desulfurization tower, an outlet tip (30) which differs in a flow velocity or a spouting pattern of absorbing solution is installed at a tip portion of the liquid column nozzle (20) so as to be detachable.
