Gas-liquid contactor and wet flue-gas desulfurization system

摘要

This invention relates to a gas-liquid contactor for efficiently bringing a gas into contact with a slurry solution, and a wet flue-gas desulfurization system using the contactor. The contactor incorporated in the system comprises a tank to be supplied with a slurry solution, a set of agitator bars held above the bottom of the tank to be horizontally rotatable, a plurality of gas supply pipes for supplying a gas to the vicinity of the agitator bars, nozzles directed to the region through which the agitator bars rotate or to its vicinity, and a plurality of liquid supply pipes for supplying a liquid to the nozzles.
