Embodiment Construction

[0058] A kind of LNG single-fuel ship of the present invention is described in detail below in conjunction with accompanying drawing.

[0059] As shown in the accompanying drawings, the structure of the LNG single-fuel ship of the present invention includes a hull, a stern peak tank 1 , a cargo hold 13 , and a fore peak tank 6 ,

[0060] The LNG gas storage tank 29 is arranged at the stern of the hull, and the stern peak tank 1, the storage tank cabin 2, and the engine room 4 are sequentially connected. The storage tank cabin 2 has holes on the main deck 16 and is designed as a sunken structure. Above the main deck 16, the other part is located below the main deck 16, and the both sides of the gas storage tank 29 are set as empty cabins 5; two rainwater wells 17 are set on the bottom diagonal of the storage tank cabin 2;

[0061] The gas delivery pipe 30 adopts a double-walled pipe in the engine room, and the periphery of the gas delivery pipe 30 near the end of the engine 19 ...

Abstract

The invention provides an LNG single-fuel ship and belongs to the technical field of ship engineering. According to the structure of the LNG single-fuel ship, a hole is formed in a main deck of a storage tank cabin, the storage tank cabin is designed to be of a sunken structure, one part of a gas storage tank is located above the main deck, the other part of the gas storage tank is located below the main deck, a double-wall pipe in an engine room is adopted as a fuel gas delivery pipe, a rectangular ventilation guide pipe is arranged on the periphery of the tail segment, close to an engine, of the fuel gas delivery pipe, and a round ventilation guide pipe is arranged on the periphery of the segment, on the upstream of the rectangular ventilation guide pipe, of the fuel gas delivery pipe; a liquid outlet pipe on the downstream of a flowmeter is divided into a main path and an auxiliary path, wherein the main path is finally connected to a mixer, and the auxiliary path is connected to the portion, between a second-stage pressure reducing valve and a downstream manual drainage pipe, of the main path through a fault opening type electromagnetic pneumatic valve and an auxiliary path safety valve; the mixer is connected with a supercharger, and the supercharger is connected with the fuel gas delivery pipe. Due to the design, the strength and the stability of the LNG single-fuel ship are improved; fuel adding, fuel feeding and safety protection are achieved, and the safety of a ship power system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ship engineering, in particular to an LNG single-fuel ship. Background technique [0002] LNG (Liquefied Natural Gas), the English abbreviation for liquefied natural gas. Natural gas is a combustible gas that is naturally extracted from gas fields, and its main component is methane. LNG is condensed into a liquid by cooling gaseous natural gas at normal pressure to -162°C. Natural gas liquefaction can greatly save storage and transportation space, and has the characteristics of large calorific value and high performance. LNG is a clean and efficient energy source. [0003] At present, some countries in Europe and the United States have begun to use LNG as fuel for maritime ships, small transport ships, ferries, ro-ro ships, and coast guard ships. China has no dedicated single-fuel LNG ships. Contents of the invention [0004] The technical task of the present invention is to solve the deficiencies o...
