Dissipator for flue gas desulfurization system

Abstract

A dissipator for percolating a mixture of flue gases and powdered lime through a body of water to remove SO.sub.2 from the flue gases includes an elongate tubular body having first and second ends. The first end of the tubular body has an inlet through which the flue gases and lime mixture is introduced into the dissipator. The second end of the tubular body is generally closed. There are a plurality of perforations in the wall of the tubular body through which the mixture of lime and flue gases can escape from the dissipator. A plurality of disrupters spaced longitudinally inside the elongate tubular body facilitate the mixing and reaction of the lime and the flue gases. Each disrupter comprises a plate with a plurality of baffles mounted on the upper thereof to facilitate the mixing of the flue gases and powdered lime mixture delivered into the dissipator. Preferably these baffles are wedge-shaped members, spaced about the circumference of the plate, and oriented with their apices pointing generally toward the center of the plate.
