Embodiment Construction

[0039] image 3 Shown is a device for transporting fumes belonging to a treatment facility, which makes it possible to clean the exhaust fumes F of the diesel engines of the diesel engines propelling the marine vessel on board the treatment facility. Smoke F contains especially sulfur oxides, especially sulfur dioxide (SO 2 ). image 3 The device makes it possible to transport the fumes F to the desulfurization scrubber 1, where image 3 Only the bottom wall 2 of the desulfurization scrubber 1 can be seen in the figure.

[0040] The scrubber 1 , the embodiment of which does not limit the invention, is functionally or even structurally similar to the scrubber V previously described with reference to FIG. 1 . The scrubber 1 thus overall assumes the shape of a tower which, during use, extends longitudinally vertically. At its base, the scrubber 1 has a bottom wall 2 from which the peripheral wall of the scrubber extends, ending in an apex: during use, the exhaust fumes F are ...

Abstract

The device comprises a vertical intake flue (30) for the fumes (F), which passes through the bottom wall (2) of the scrubber (1) and which in the bottom part comprises a sheath (31) consisting of Made of material resistant to a temperature of at least 350° C. and arranged on the outside of the scrubber. In order to limit salt encrustation in the device, the flue comprises a duct (32) with multiple walls in the top part. The duct (32) comprises both an inner wall (32.1) made of a material resistant to temperatures of at least 350°C and an outer wall (32.2) separated from the inner wall by an insulator (32.3). In addition, the conduit is at least partially arranged inside the scrubber while extending longitudinally upwardly from the bottom wall of the scrubber for at least 300mm.

Description

【Technical field】 [0001] The invention relates to a device for conveying exhaust fumes from marine vessel engines into a scrubber. 【Background technique】 [0002] Whether passenger ships or other ships, marine vessels primarily use fuel oil as fuel for diesel engines to propel them. The fuel oil contains up to 5 wt% sulfur, most typically between 0.5 wt% and 3.5 wt%. During combustion in the engine, this sulfur is converted to sulfur dioxide (SO 2 ). As a result, the exhaust from these engines is acidic and harmful. Therefore, ships must contain components for reducing the emission of sulfur dioxide from these fumes before they are released into the atmosphere. [0003] The most commonly proposed technique on board ships to capture the sulfur dioxide present in the exhaust consists of using sea water to scrub the fumes. This technology is achieved by using the alkalinity of seawater to neutralize sulfur dioxide through scrubbers, and generally does not require the use o...
