Ship with closed sulfur removal function

Abstract

The invention belongs to the technical field of ships, and discloses a ship with a closed sulfur removal function. The ship comprises an upper platform, two fuel oil cabins, a slurry supply cabin anda washing water discharge cabin, wherein the upper platform is provided with a head and a tail, the two fuel oil cabins are arranged on the two sides of the head respectively, the sides, which are away from each other, of the two fuel oil cabins are each provided with a double-shell structure to form an accommodating cavity, the slurry supply cabin is arranged in one accommodating cavity, and thewashing water discharging cabin is arranged in the other accommodating cavity. According to the ship with the closed sulfur removal function, the stability of the ship body and the sailing safety canbe considered at the same time on the premise of not additionally occupying a cargo hold area, and the space is reasonably utilized to arrange a closed sulfur removal system.

Description

technical field [0001] The invention belongs to the technical field of ships, in particular to a ship with a closed desulfurization function. Background technique [0002] In order to reduce air pollution from ships, the global fuel oil content standard of 0.5% m / m came into effect on January 1, 2020. A large number of ships have reached this standard by using marine desulfurization towers (exhaust gas cleaning systems). System) includes open and closed types. The open system is relatively simple, but more and more port states currently prohibit the use of this system in their ports or waters. Closed systems generally refer to the use of sodium-based lye (such as NaOH solution) or magnesium-based slurry (such as Mg(OH) 2 or MgO solution) as the desulfurizer wet desulfurization system, the closed system needs to use redundant lye neutralization system, the system is relatively complicated, and a whole set of compartments needs to be added in the hull: desulfurizer storage co...

AI Technical Summary

Problems solved by technology

[0003] For the convenience of system operation, the desulfurization system is generally arranged in the hull, but the space in the compact hull is already very tight. If the length of the engine room is increased due to the addition of a closed desulfurization system, the cargo hold area will be occupied and the cargo oil will be reduced. cabin capacity, thereby reducing the operating income, if not properly arranged, it will also affect the stability and safety of the hull navigation
