Description
Technical Field
[0001] The utility model relates to the technical field of ships, in particular to an arrangement of a methanol daily tank and a fuel preparation room of a methanol dual-fuel ship. Background Art
[0002] At present, most of the methanol dual-fuel ships disclosed in patent documents are container ships and liquid cargo ships, and the methanol fuel daily tanks and fuel preparation rooms are arranged in the ship's loading area.
[0003] Patent application number CN115158539A discloses a methanol fuel containment and supply system layout for large dual-fuel container ships. This patent application addresses the layout of methanol fuel-related equipment for container ships. In this solution, the methanol fuel daily tank and methanol fuel preparation room are located in the container loading area at the bow of the engine room canopy above the main deck.
[0004] Patent application publication number CN113047994A discloses a methanol-fuel dual-fuel vessel. This technical solution addresses the layout of methanol-fuel-related equipment for liquid cargo vessels. In this solution, the methanol fuel service tanks and methanol fuel preparation room are located above the main deck in the cargo area. The large available space on the main deck of a liquid cargo vessel facilitates the placement of the methanol fuel service tanks and methanol fuel preparation room within the cargo area.
[0005] Patent application number CN115092331A discloses a dual-fuel container ship. This patent application addresses the layout of methanol fuel-related equipment for container ships. In this solution, the methanol fuel daily tank and methanol fuel preparation room are located in the methanol fuel processing tank at the bow of the engine room, below the container stacking area. The methanol fuel processing tank utilizes a portion of the cargo hold space.
[0006] In the above prior art, the methanol fuel daily tank and the fuel preparation room are both arranged in the cargo hold area. The above arrangement is more friendly to ship types such as container ships and liquid cargo ships.
[0007] However, these arrangements are not applicable to bulk carriers. The main reasons are:
[0008] First, the cargo hold area of a bulk carrier has a large area of cargo hatch covers, leaving no ample space for the arrangement of a methanol fuel daily tank and a fuel preparation room; second, during cargo loading and unloading, there is a risk of heavy objects falling from the cargo hold area, which may cause mechanical damage to the methanol fuel daily tank and the fuel preparation room located on the deck of the cargo hold area; third, during cargo loading and unloading, the cargo hold area is very dusty, which can easily enter the fuel preparation room in large quantities through the ventilation system of the fuel preparation room, posing a safety hazard to the operation of the fuel supply equipment arranged in the fuel preparation room; fourth, if the methanol fuel daily tank and the fuel preparation room are both arranged in the cargo hold area below the main deck, a large amount of cargo hold space will be occupied, reducing the ship's loading capacity, and it will be difficult to set up passages and ventilation in and out of the methanol fuel daily tank and the fuel preparation room.
[0009] It can be seen that the existing technology has the technical disadvantage that the arrangement of the methanol fuel daily tank and the fuel preparation room is not suitable for bulk carriers. Utility Model Content
[0010] The technical problem to be solved by the utility model is to overcome the above-mentioned defects in the prior art and provide a methanol daily tank and fuel preparation room arrangement for a methanol dual-fuel ship.
[0011] The utility model solves the above technical problems through the following technical solutions:
[0012] A methanol daily tank and fuel preparation room arrangement of a methanol dual-fuel ship comprises a methanol fuel daily tank and a fuel preparation room; the methanol fuel daily tank and the fuel preparation room are both arranged on the main deck, and the methanol fuel daily tank and the fuel preparation room are arranged adjacent to each other on the same side of the engine room shed; the fuel preparation room is located above the engine room; and an isolation space is provided outside the methanol fuel daily tank.
[0013] There are isolated void spaces on the top and bottom of the methanol fuel daily tank; there is no isolated void space on the bulkhead of the methanol fuel daily tank adjacent to the fuel preparation room.
[0014] The bulkhead of the methanol fuel daily service tank adjacent to the open air area is provided with an isolated void compartment.
[0015] Alternatively, the bulkhead of the methanol fuel daily use tank adjacent to the open air area is provided with a protective component for preventing mechanical damage to the methanol fuel daily use tank.
[0016] A methanol fuel supply unit is provided in the fuel preparation room, and the methanol fuel supply unit is connected to the methanol fuel daily cabin.
[0017] A main engine methanol fuel supply valve group is provided in the fuel preparation room; the main engine methanol fuel supply valve group is connected to the methanol fuel supply unit; and the main engine methanol fuel supply valve group is connected to the main engine provided in the engine room through a methanol fuel supply pipe.
[0018] The methanol fuel supply pipe located in the cabin is a double-walled pipe.
[0019] A generator methanol fuel supply valve group is provided in the fuel preparation room; the generator methanol fuel supply valve group is connected to the methanol fuel supply unit.
[0020] A generator methanol fuel supply high-pressure pump is provided in the fuel preparation room; one end of the generator methanol fuel supply high-pressure pump is connected to the generator methanol fuel supply valve group; the other end of the generator methanol fuel supply high-pressure pump is connected to the generator.
[0021] The ship is equipped with a pressure control valve for regulating the internal pressure of the methanol fuel daily tank, and the pressure control valve is connected to the methanol fuel daily tank through a breathable pipe.
[0022] The pressure control valve is located at the aft end of the main deck.
[0023] There is an A60 fire separation component or an isolation cabin between the fuel preparation room and the engine room.
[0024] There is an A60 fire separation component or an isolation cabin between the fuel preparation room and the cabin shed.
[0025] The beneficial effects of the present invention include: the methanol fuel daily tank and fuel preparation room are located to the side of the main deck engine room shed, above the engine room. This layout is well-suited for ships such as bulk carriers, where space is limited for the methanol fuel daily tank and fuel preparation room in the cargo hold area. This layout, when applied to bulk carriers, significantly reduces the risk of mechanical damage during cargo loading and unloading, which is often associated with their placement in the cargo hold area. The methanol fuel daily tank and fuel preparation room are located away from the cargo hold area. This layout, when applied to bulk carriers, effectively prevents cargo dust from entering the fuel preparation room through the ventilation system during cargo loading and unloading, potentially adversely affecting the normal operation of fuel supply equipment. The methanol fuel daily tank's location to the side of the main deck engine room shed facilitates the placement of its vent pipe and pressure control valve. The pressure control valve is located aft of the main deck, close to the methanol fuel daily tank. This protects the vent pipe and pressure control valve from mechanical damage during cargo loading and unloading, as well as the effects of cargo dust on the pressure control valve's operation. The present invention is well-suited for use on ships such as bulk carriers. BRIEF DESCRIPTION OF THE DRAWINGS
