<p>PROBLEM TO BE SOLVED: To provide a wet stack gas desulfurizing device capable of improving the absorption efficiency of sulfur oxides and also excellent in the recovery of the fine powder such as ash, obviating the maintenance administration of a spray nozzle, etc., and also low in floor space. SOLUTION: A stationary mixer 3 for subjecting stack gas 10 and an absorbing solution 2 to gas-liquid contacting and for mixing the stack gas 10 and the absorbing solution 2 is arranged at the inside of a absorption tower 1 to which stack gas 10 is supplied in a state whose longitudinal direction is substantially vertical, and an absorbing solution sprinkler pipe 4 for spraying the absorbing solution 2 to the stationary mixer 3 is arranged at the upper end side of the stationary mixer 3. An absorbing solution tank 7 for storing the absorbing solution 2 is provided below the stationary mixer 3, and the absorbing solution tank 7 and the absorbing solution sprinkler pipe 4 are connected by an absorbing solution circulation line 9 and the absorbing solution 2 in the absorbing solution tank 7 is supplied to the absorbing solution sprinkler pipe 4.</p> |
