SOx Semi dry reactor enhancing SOx removal efficiency by improving a gas flow pattern

摘要

The present invention relates to a semi-dry reactor tower having enhanced efficiency of removing SO_x by improving patterns of gas flow, which comprises: a main reaction tower unit (210) having a shape of a hollow cylinder and erected vertically; a double pipe structure unit (220) disposed in a lower part of the main reaction tower unit (210) and having two hollow cylinders concentrically overlapped inside and outside; a gas insertion duct (240) connected to the outer cylinder (221) of the double pipe structure unit (220) to make exhaust gas introduced into the space between the outer cylinder (221) and the inner cylinder (223) while receiving exhaust gas discharged from facility for discharging air pollutants and introducing the same into the double pipe structure unit (220); a slurry supply means having a plurality of injection nozzles installed in a circumferential direction around the main reaction tower unit (210) on the outer circumference of the lower part of the main reaction tower unit (210) at predetermined intervals to inject slurry-type liquid toward a center of the main reaction tower unit (210); a horizontal discharge guide pipe (250) extended from the side of the upper part of the main reaction tower unit (210) in a transverse direction; and a gas discharge duct (260) extended from an end portion of the horizontal discharge guide pipe (250) in a vertical direction.
