Washing tower suitable for desulfurization of ship waste gas

The invention discloses a washing tower suitable for desulfurization of ship waste gas, wherein a baffle plate is horizontally arranged right above an upper port of a waste gas inlet and is fixedly connected with the waste gas inlet through a fixing strip; a first gas collecting hopper covers the upper part of the baffle plate and is of a funnel-shaped structure with a downward opening; a group ofwashing liquid through holes which are communicated up and down are formed in the outer side of the first gas collecting hopper in the circumferential direction; a swinging gas collecting barrel witha downward opening is arranged above the second gas collecting hopper and can rock in the tower body, so that a region between the swinging gas collecting barrel and the second gas collecting hopperis a secondary reaction region; and second nozzles are densely distributed on the inner top surface of the swinging gas collecting barrel. The swing gas collecting barrel in the secondary reaction region effectively utilizes th
