Embodiment 1

[0031] This embodiment discloses a method for arranging the engine room of a small multi-purpose hydrogen-powered ship, such as figure 1 As shown, a hydrogen fuel cell 1, an auxiliary system 2 and a water collecting tank 22 are arranged in the engine room of the ship. The hydrogen fuel cell 1 and the auxiliary system 2 are fixed on a common base 14 by bolts, and the common base 14 is welded and fixed to the engine room. At the bottom, the provision of a common base can facilitate the overall disassembly and hoisting; the centerlines of the fuel cell 1 and the auxiliary system 2 are coincident with the middle of the ship, so as to avoid the deviation of the center of gravity of the ship. The auxiliary system is arranged at the end of the engine room near the bow, and the hydrogen fuel cell is arranged at the stern of the engine room near the end of the hydrogen cylinder. The arrangement near the hydrogen cylinder can shorten the length of the hydrogen pipe, reduce the probabilit...

Abstract

The invention provides a method for arranging the engine room of a small multi-purpose hydrogen-powered ship. A hydrogen fuel cell, an auxiliary system and a water collection tank are arranged in the engine room, the auxiliary system is arranged near the bow, and the hydrogen fuel cell is arranged near the hydrogen cylinder at the stern; The heat device, the refrigerant inlet and the refrigerant outlet of the auxiliary system are respectively connected with the sea water, and the heat medium inlet and the heat medium outlet are respectively connected with the cooling liquid outlet and the cooling liquid inlet of the hydrogen fuel cell; the hydrogen fuel cell is provided with a hydrogen gas inlet, an air inlet, an exhaust Gas port and water outlet; the hydrogen inlet of the hydrogen fuel cell communicates with the hydrogen cylinder through the hydrogen tube, the water outlet of the hydrogen fuel cell communicates with the water collection tank, and the water collection tank communicates with the generated water row outboard pipe through the first drainage pump. The invention not only ensures the smooth realization of various equipment and system functions in the engine room, but also makes full use of the space, is safe, reliable, flexible and convenient, easy for construction and maintenance, and realizes a zero breakthrough in the modular arrangement of the engine room of a small hydrogen-powered ship.

Description

technical field [0001] The invention relates to a hydrogen power system technology, in particular to a method for arranging a cabin of a small multi-purpose hydrogen power ship. Background technique [0002] The engine room of the ship is the installation space of the ship's power plant and the heart of the ship. The layout of the engine room directly affects the safety and reliability of the ship. Oil-fired main engines and generators are usually installed in the engine room of traditional ships. Hydrogen energy is a new type of completely green and pollution-free energy, which is gradually replacing traditional energy in various fields. Small ships powered by hydrogen energy are only occasionally seen in scientific research before the projects involved in the present invention, and there is no product. The engine room layout of hydrogen-powered small ships is very different from that of conventional ships. The main body of the cabin is a hydrogen fuel cell. This requi...
