Problems solved by technology

[0004] However, due to the large size of the scrubber, the chimney space of conventional ships is not enough, and the chimney needs to be enlarged in the horizontal and / or vertical direction, which has a great impact on the layout of the ship

Abstract

The invention provides a desulfurization and emission reduction device and a ship, and relates to the technical field of ships. The desulfurization and emission reduction device comprises a chimney, adesulfurization treatment mechanism and a first exhaust pipe; the desulfurization treatment mechanism is arranged at the top of the chimney; a second exhaust pipe is arranged in the chimney; and thedesulfurization treatment mechanism is communicated with the first exhaust pipe and the second exhaust pipe and is used for conducting desulfurization treatment on waste gas exhausted by the second exhaust pipe. Waste gas is exhausted out of the chimney through the second exhaust pipe to the desulfurization treatment mechanism and then enters the first exhaust pipe after being subjected to desulfurization treatment, and the treated waste gas is exhausted to the outside through the first exhaust pipe. Because the desulfurization treatment mechanism is arranged at the top of the chimney, a worker only needs to additionally install the desulfurization treatment mechanism and the second exhaust pipe above the original chimney without changing the size of the original chimney, the layout of a ship is not greatly influenced, and the exhaust gas back pressure of an exhaust pipe of a diesel engine on the ship is not influenced. The desulfurization and emission reduction device is suitable forbeing additionally installed on an old ship for upgrading and being assembled on a new ship.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a desulfurization and emission reduction device and a ship. Background technique [0002] At present, ships are basically equipped with desulfurization and emission reduction devices. The desulfurization process is: pump seawater from the seawater pump box through the seawater pump corresponding to the desulfurization system, introduce seawater into the desulfurization system, use seawater to clean the exhaust gas, and then discharge it into the sea. , to reduce sulfur emissions from ships. [0003] In the prior art, the desulfurization and emission reduction device generally performs desulfurization treatment on the flue gas before it exits the chimney, and the scrubber is arranged in the chimney of the engine room. Pass the flue gas and seawater into the washing tower for desulfurization treatment, and then discharge the treated flue gas and seawater out of the washing tower. ...
