<p>PURPOSE:To provide a flue gas desulfurizer provided with a high-performance and compact absorption tower capable of economically removing the mist without being affected by the superficial velocity of a waste gas in the tower. CONSTITUTION:A spray 20 directed toward the wall of an absorption tower 3 at the turning of a waste gas 1 at the tower top is provided to form a wetted wall on the wall surface of the tower top, the waste gas 1 is turned on the wetted wall, the liq. mist tending to splash toward the downstream side along with the waste gas is inertially collided with the wall surface at the turning and collected on the wall surface. The amt. of mist is remarkably reduced at the outlet of the tower 3, and the remaining fine droplet only is removed by a vertical demister 18. A horizontal in-tower demister which has been set in the tower 3 can be dispensed with, hence the height of the tower is reduced, and the superficial velocity of the tower is determined only in consideration of absorptivity.</p> |
