At present, along with the development of clean energy, methanol has the advantages of cleanness, environmental protection, strong availability and the like, methanol is gradually adopted as a ship fuel in the field of ship shipping, and when a ship methanol fuel supply system is shut down or maintained in a fault mode, all pipelines, engines and other discharged methanol fuels are required to be stored in a methanol discharging cabinet together from the safety point of view, and the methanol fuel is required to be returned to the shore to be processed by special equipment, namely, for ships, a discharging collecting cabin with enough volume is required to be reserved on the ship, and on the other hand, the burden of the ship is further increased in the process of ship shipping.
According to the design specifications of the ship, the methanol supply pipeline is a double-wall pipe in the engine room. When the double-wall pipe is broken and leaked or fuel is switched, the methanol in the double-wall pipe needs to be discharged. There are generally two approaches to deal with these methanol blowdown. A methanol discharging cabin is arranged at a lower position outside a cabin, a discharging pipeline is arranged to discharge methanol to the discharging cabin, a methanol discharging pump is arranged to discharge the methanol in the discharging cabin to a daily cabin, the methanol discharging cabin cannot be directly arranged in the cabin as a methanol storage cabin, and an isolation empty cabin is arranged around the methanol discharging cabin to be isolated from other cabin cabinets, so that a large space is occupied. Another approach is to provide a water-filled bleed tank in the nacelle to which methanol is bled, the methanol solution concentration in the tank being less than 10%, so that the regulations allow the bleed tank and bleed pump to be placed in the nacelle. However, the specification does not allow the methanol solution in the discharge tank to be discharged directly from the sea, so that a special transfer pump is required for discharging the bank.
