BYPASS-FREE INDUCED SHIP EXHAUST GAS DESULFURIZATION SYSTEM AND AIR INDUCING METHOD THEREFOR

摘要

A bypass-free induced ship exhaust gas desulfurization system and an air inducing method therefor. A main flue (2) of the system is internally tangent to the inside of a desulfurizing tower (1). The main flue (2) is provided with an exhaust gas outlet (21) at one side of a line of centers of the desulfurizing tower (1) and the main flue (2). The exhaust gas outlet (21) is connected to an inlet of an exhaust gas guiding section (11). An outlet of the exhaust gas guiding section (11) is connected to an exhaust gas desulfurizing section (12) of the desulfurizing tower (1). The exhaust gas guiding section (11) comprises a plurality of nozzles (111) disposed between the desulfurizing tower (1) and the exhaust gas outlet (21). The spraying directions of the nozzles (111) are the same as the flowing direction of exhaust gas exhausted from the exhaust gas outlet (21). Because of the bypass-free design and no use of a ballistic cap, the occupied area is small, exhaust pressure loss is low, and exhaust gas is sufficiently cooled.
