Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a chimney area structure of a large-scale methanol fuel container ship. Background Art

[0002] In the marine industry, the development of methanol dual-fuel container ships is still in its infancy. Vessels must integrate a complete methanol fuel system alongside their existing fuel oil systems to meet the demands of dual-fuel operation. Currently, the methanol service tanks and methanol clarifier tanks on dual-fuel vessels are typically located aft of the engine room, further compressing engine room space and increasing the complexity of piping installation.

[0003] Therefore, it is necessary to provide a chimney area structure for a large methanol fuel container ship to solve the above technical problems. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art and provide a chimney area structure for a large methanol fuel container ship, which optimizes the layout of the methanol daily tank and the methanol clarification tank, saves engine room space, and simplifies the laying of engine room pipelines.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A chimney area structure of a large methanol fuel container ship, comprising a main deck layer structure, an A deck layer structure, a B deck layer structure and a C deck layer structure. The chimney area structure is provided with a fuel room on the starboard side, the bottom of the fuel room is located on the main deck, the top of the fuel room is located on the C deck, a methanol daily tank is provided inside the fuel room, a methanol clarification tank is provided on the top of the methanol daily tank, a methanol equipment preparation room is provided in the engine room below the main deck, the methanol equipment preparation room is located directly below the methanol daily tank, the methanol daily tank and the methanol equipment preparation room are connected by a pipeline, the methanol equipment preparation room is provided with an independent structural air duct, and the structural air duct runs through the fuel room and extends to above the C deck.

[0007] Preferably, an exhaust pipe channel is provided in the middle of the chimney area structure, and the exhaust pipe channel passes through the main deck layer structure, the A deck layer structure, the B deck layer structure and the C deck layer structure in sequence, and continues to extend upward. Cabin wind fan sheds are provided on the left and right sides of the exhaust pipe channel. The cabin wind fan shed on the left is respectively located in the A deck layer structure and the B deck layer structure, and the cabin wind fan shed on the right is respectively located in the A deck layer structure, the B deck layer structure and the C deck layer structure.

[0008] Preferably, in the main deck structure located on the left side of the exhaust pipe channel, there are provided an oxygen room, an acetylene room, a deck storage room, a cold storage room, a fire control room and a cabin fan room from left to right.

[0009] Preferably, a cable storage room is provided in the A-deck structure located on the left side of the exhaust pipe passage.

[0010] Preferably, shore-connected cable winches are symmetrically arranged in the B deck layer structure located on the left and right chords of the exhaust pipe channel, and a response room is provided on the right side of the left shore-connected cable winch.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. By optimizing the internal layout of the chimney area structure, the methanol daily tank and methanol clarification tank are arranged on the starboard side of the chimney area structure, without occupying the deck area and cargo hold area, thereby improving the overall transportation capacity of the ship.

[0013] 2. The methanol daily service tank is arranged directly above the methanol equipment preparation room, shortening the distance between each methanol equipment and the methanol system pipelines. The preparation room is set up in the upper platform area of the engine room, which is convenient for pipeline connection to the engine room equipment.

[0014] 3. An independent structural air duct is installed in the methanol equipment preparation room, running through the fuel room and extending to above the C deck, reducing the safety risk in the engine room.

[0015] 4. The emergency room, oxygen room, acetylene room, deck storage room, cold storage room, fire control room, engine room fan room and cable storage room are arranged on the port side of the chimney area structure to ensure the normal operation of various functions of the ship.

[0023] like Figures 1 to 3 As shown, a chimney area structure of a large methanol fuel container ship, the chimney area structure includes a main deck layer structure, an A deck layer structure, a B deck layer structure and a C deck layer structure. The chimney area structure is provided with a fuel room 16 on the starboard side, the bottom of the fuel room is located on the main deck, and the top of the fuel room is located on the C deck. A methanol daily tank 1 is provided inside the fuel room, and a methanol clarification tank 2 is provided on the top of the methanol daily tank. A methanol equipment preparation room 3 is provided in the engine room below the main deck, and the methanol equipment preparation room is located directly below the methanol daily tank. The methanol daily tank and the methanol equipment preparation room are connected by a pipeline. The methanol equipment preparation room is provided with an independent structural air duct 15, which runs through the fuel room and extends to above the C deck. An exhaust pipe channel 7 is installed in the middle of the chimney area structure, and the exhaust pipe channel runs through the main deck in sequence. The exhaust pipe passage is composed of a plate layer structure, an A deck layer structure, a B deck layer structure and a C deck layer structure, and continues to extend upward. There are engine room fan sheds 6 on the left and right sides of the exhaust pipe passage. The left engine room fan shed is located in the A deck layer structure and the B deck layer structure respectively, and the right engine room fan shed is located in the A deck layer structure, the B deck layer structure and the C deck layer structure respectively. The main deck layer structure on the left side of the exhaust pipe passage is provided with an oxygen room 8, an acetylene room 9, a deck storage room 10, a cold storage room 11, a fire control room 12 and an engine room fan room 13 from left to right.

[0024] A layout principle of the chimney area structure of a large-scale methanol fuel container ship: Compared with the current form of arranging the methanol daily tank and the methanol clarification tank at the stern of the engine room or on the stern deck, the present invention creatively arranges the methanol daily tank and the methanol clarification tank inside the chimney area structure, and arranges the methanol equipment preparation room in the engine room directly below the methanol daily tank. This layout method not only saves space in the engine room and deck, but also effectively reduces the distance for laying pipelines between the methanol equipment preparation room and the methanol daily tank. Straight pipes are laid from top to bottom, which reduces the difficulty of laying pipelines. The oxygen room, acetylene room, deck storage room, cold storage room, fire control room and engine room fan room, response room and cable storage room originally arranged in the chimney area structure are all arranged on the port side of the chimney area structure, effectively improving the utilization rate of the internal space of the chimney area structure.
