Embodiment 1

[0039] like Figure 1-Figure 4 As shown, the present invention discloses a super-large container ship, which includes a dual-fuel gas supply system for a super-large container ship, wherein the gas supply system for a dual-fuel super-large container ship in this embodiment includes an LNG fuel tank 1, an LNG fuel tank 1 is arranged below the deck 17. For safety design, an empty compartment is arranged between the LNG fuel tank 1 and the adjacent cargo tank. The LNG fuel tank 1 mentioned herein can be an IMO B-type tank or a membrane-type tank.

[0040] The gas supply system for a dual-fuel ultra-large container ship in this embodiment also includes an engine room 15, which is arranged below the deck 17, and the engine room 15 is located at the tail of the ship.

[0041]The gas supply system for dual-fuel ultra-large container ships of this embodiment also includes a gas treatment room 5, which is arranged above the deck 17, wherein the fuel in the LNG fuel tank 1 is transpor...

Embodiment 2

[0058] Such as Figure 5 As shown, the LNG fuel tank 1 of this embodiment is arranged in the middle section of the ship and below the superstructure 24 . The LNG fuel tank 1 utilizes a relatively regular cross-sectional area in the middle section of the ship, and the shape of the fuel tank in this area is more regular, which has less impact on the cargo space. But it is far away from the gas equipment in the cabin.

Abstract

The invention discloses a dual-fuel air supply system of an ultra-large container ship and the ultra-large container ship. The dual-fuel air supply system of the ultra-large container ship comprises an LNG (Liquefied Natural Gas) bunker, a cabin and a gas processing room, wherein the LNG bunker is arranged below a deck, the cabin is arranged below the deck and is located on the tail of the ship, the gas processing room is arranged above the deck, and fuel in the LNG bunker is conveyed to the gas processing room to be processed and is conveyed to gas equipment in the cabin. According to the dual-fuel air supply system of the ultra-large container ship, the LNG bunker is arranged below the deck, and the arrangement of the LNG bunker comprehensively considers the influence of the LNG bunker on the stability of the ship, the partition of fire separation and hazardous areas and the convenience in arrangement of a natural gas pipeline. Additionally, the inner space of the ultra-large container ship is used to the maximum, the maximum effective volume can meet the requirement that LNG fuel can be used by the ultra-large container ship on the entire route, and at least the requirement thatthe ship sails in a round trip on a set route can be met.

Description

technical field [0001] The invention relates to a dual-fuel gas supply system for an ultra-large container ship and the ultra-large container ship. Background technique [0002] In the face of the strict "Tier III" emissions in the future, there are currently two main ways to deal with them: either continue to use traditional fuel oil and use after-treatment devices; or use natural gas power systems. [0003] The main schemes of using after-treatment devices are: installing NOx after-treatment devices in the exhaust system - Selective Catalytic Reduction Reactor (SCR); Exhaust Gas Recirculation (EGR); Desulfurization Scrubber (Scrubber); sulfur oil (MGO). However, in addition to the investment in the initial equipment cost, the adoption of the above post-processing device solutions also requires considerable operation and maintenance costs after they are put into use. [0004] Due to its high calorific value, no sulfur, clean combustion, and low emissions, natural gas will...
