Description

Technical Field

[0001] The invention relates to the technical field of ship construction, and in particular to a methanol cabin arrangement structure of a methanol dual-fuel container ship. Background Art

[0002] In the field of ships, the use and research and development of methanol dual-fuel ships is still in its infancy. The main body of the ship needs to build a complete methanol fuel system on the original fuel system to meet the needs of dual-fuel operation. At present, the methanol fuel system of dual-fuel ships usually consists of a filling station, a methanol fuel storage tank, a methanol daily tank, a methanol pump room and a methanol fuel preparation room, but the existing layout structure has many defects: 1. The transfer of methanol fuel from the methanol storage tank to the methanol daily tank needs to be achieved through the methanol transfer pump in the methanol pump room. Not only does the methanol pump room occupy a large space, but it also requires additional transfer pipelines to be laid, with low space utilization and reduced container loading; 2. A purge and residual discharge device needs to be installed in the pipeline between the filling station and the methanol storage tank, which greatly increases the installation cost and increases the difficulty of operation for the crew; 3. Each methanol fuel user needs to install a special discharge collection device.

[0003] Therefore, it is necessary to provide a methanol dual-fuel container ship methanol cabin layout structure to solve the above technical problems. Summary of the invention

[0004] The purpose of the present invention is to provide a methanol dual-fuel container ship methanol cabin layout structure in view of the deficiencies in the prior art, which can further improve the utilization rate of the ship space, reduce the ship construction cost, and improve the safety factor of the ship.

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

[0006] A methanol dual-fuel container ship methanol cabin layout structure includes a ship body, the ship body includes a main deck, a superstructure, an engine room and a cargo hold, the superstructure is arranged above the main deck, the engine room is arranged below the main deck corresponding to the superstructure, a methanol storage tank is arranged below the main deck in front of the superstructure, the rear end of the methanol storage tank is arranged adjacent to the engine room, and the front end of the methanol storage tank is arranged adjacent to the cargo hold, the methanol storage tank includes a first methanol storage tank and a second methanol storage tank arranged in sequence along the width direction of the ship body, and the tops of the first methanol storage tank and the second methanol storage tank together form a "convex"-shaped structure along the length direction of the ship body The methanol storage tank is provided with methanol filling stations on both sides along the width direction of the ship body, and the methanol filling stations are connected to the top of the methanol storage tank through pipelines. A methanol fuel preparation room is provided below the first methanol storage tank, and isolation air compartments are provided around the first methanol storage tank, the second methanol storage tank and the methanol fuel preparation room, which are separated from other cabins by the isolation air compartments. A methanol supply unit and a discharge tank are provided in the methanol fuel preparation room, and the methanol fuel is transported to each methanol fuel user through the methanol supply unit. The height of the methanol fuel preparation room is lower than the height of each methanol fuel user and forms a height difference. The methanol fuel preparation room and the engine room are connected to each other through an airlock room.

[0007] Preferably, the cabin outside the isolation void compartment is a ballast tank, and the top of the ballast tank, the outer bulkhead of the isolation void compartment and the outer plate of the ship body together form a second deck passage.

[0008] Preferably, the methanol fuel users include a methanol dual-fuel host, a methanol dual-fuel generator set and a methanol dual-fuel boiler.

[0009] Preferably, the methanol fuel preparation room forms a closed space.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] 1. The methanol filling station is directly arranged above the methanol storage tank, which shortens the filling pipeline and uses gravity to directly purge the methanol in the filling pipeline. There is no need to install an additional purge unit, which simplifies the filling process, reduces construction costs, and improves the safety of the filling system.

[0012] 2. The methanol fuel preparation room is arranged below the methanol storage tank. The methanol supply unit in the methanol fuel preparation room can use gravity to directly supply liquid from the methanol storage tank, eliminating the deep well pump, methanol pump room, methanol daily tank, transfer pipeline and related control systems in the methanol storage tank, greatly reducing the construction cost and releasing a large amount of cargo space for the cargo hold.

[0013] 3. Arrange the methanol fuel preparation room below each methanol fuel user to form a height difference, and use gravity to discharge and collect the methanol in the circuit of each methanol fuel user, so that the methanol purge in the methanol circuit is cleaner and safer.

[0014] 4. This arrangement reduces the use of structural steel plates, reduces the weight of structural steel plates, and increases the ship's carrying capacity. BRIEF DESCRIPTION OF THE DRAWINGS
