Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to an arrangement structure of a methanol daily tank of a methanol dual-fuel bulk carrier. Background Art

[0002] As new energy ships develop better and better, the demand for methanol dual-fuel ships is increasing. The layout structure of methanol fuel-related cabins is a major difficulty in the ship design and construction process. If the methanol daily tank and fuel preparation room are arranged under the main deck, the cargo hold space of the bulk carrier will be greatly compressed. Summary of the invention

[0003] The purpose of the present invention is to address the deficiencies in the prior art and to provide a methanol daily tank layout structure for a methanol dual-fuel bulk carrier in which the methanol daily tank is independently arranged and does not occupy the main deck and cargo hold space.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a methanol daily tank layout structure of a methanol dual-fuel bulk carrier, including a methanol daily tank, a fuel preparation room, and an engine room shed. The fuel preparation room is arranged at the height of the A deck, and columns are arranged at the bottom of the fuel preparation room. The bottom of the column is fixed on the main deck, and the column supports the bottom of the fuel preparation room. The methanol daily tank is arranged at the height of the B deck, and the methanol daily tank is located above the fuel preparation room. The fuel preparation room and the methanol daily tank are both arranged adjacent to the engine room shed.

[0005] Preferably, isolation cabins are provided around the methanol daily cabin.

[0006] Preferably, the fuel preparation room is provided with a ventilation duct, the air inlet and air outlet of the ventilation duct are both arranged in the fuel preparation room, a check damper and an exhaust fan are arranged near the air outlet, and the ventilation duct is arranged along the top corners of the fuel preparation room and leads to the isolation cabin.

[0007] Preferably, a portion of the ventilation duct located in the fuel preparation room is provided with a first ventilation grille, and a portion of the ventilation duct located in the isolation cabin is provided with a second ventilation grille.

[0008] Preferably, the fuel preparation room is also provided with a methanol purge tank and a methanol bilge discharge tank.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] 1. The fuel preparation room and methanol daily tank are raised to avoid taking up too much main deck space and ensure the normal operation of the anchor winch.

[0011] 2. Convenient for ventilation pipe layout, the ventilation pipe is set up independently and can lead directly to the outdoors.

[0012] 3. The entire cabin structure is close to the chimney, does not occupy the cargo hold space, does not affect the ship's load capacity, and fully guarantees the ship's transportation capacity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0020] like Figures 1 to 5The methanol dual-fuel bulk carrier shown has a methanol daily tank 15 arrangement structure, including a methanol daily tank 15, a fuel preparation room 10, and an engine room shed 12. The fuel preparation room 10 is arranged at the height of the A deck. A column 11 is arranged at the bottom of the fuel preparation room 10. The bottom of the column 11 is fixed on the main deck. The column 11 supports the bottom of the fuel preparation room 10. The methanol daily tank 15 is arranged at the height of the B deck. The methanol daily tank 15 is located above the fuel preparation room 10. The fuel preparation room 10 and the methanol daily tank 15 are both arranged adjacent to the engine room shed 12. The space on the main deck needs to be arranged with an anchor winch, and the fuel preparation room 10 and the methanol daily tank 15 cannot be arranged directly on the main deck. Therefore, the fuel preparation room 10 is supported by arranging columns 11 on the main deck, and the fuel preparation room 10 and the methanol daily tank 15 are arranged up and down, thereby shortening the distance between the methanol system pipelines, and the methanol daily tank 15 is arranged independently outdoors for higher safety. The methanol pipeline of the methanol daily tank 15 is directly connected to the engine room through the engine room shed 12, thereby reducing the layout distance of the methanol pipeline. Most importantly, the previous form of setting the fuel preparation room 10 under the main deck and occupying the cargo hold is abandoned, thereby maximizing the cargo hold space.

[0021] An isolation cabin 22 is arranged around the methanol daily cabin 15, and a ventilation duct 23 is arranged in the fuel preparation room 10. The air inlet 17 and the air outlet 16 of the ventilation duct 23 are both arranged in the fuel preparation room 10. A check damper 18 and an exhaust fan 19 are arranged near the air outlet 16. The ventilation duct 23 is arranged along the top corner of the fuel preparation room 10 and leads to the isolation cabin 22. The part of the ventilation duct 23 located in the fuel preparation room 10 is provided with a first ventilation grille 20, and the part of the ventilation duct 23 located in the isolation cabin 22 is provided with a second ventilation grille 21. Accordingly, since the methanol daily cabin 15 is arranged directly above the fuel preparation room 10 and the methanol daily cabin 15 is arranged independently of the outdoors, the length of the ventilation duct 23 of the fuel preparation room 10 is greatly reduced, and the air inlet 17 and the air outlet 16 lead directly to the outdoors, without the need to set up extra pipelines. The fuel preparation room 10 is also provided with a methanol purge cabin 14 and a methanol tank bottom discharge cabin 13.
