Description

Technical Field

[0002] In traditional ship power systems, generators play a vital role in converting mechanical energy into electrical energy for use by various systems and electrical equipment on board. Ship generators are usually driven by diesel engines. Although this design is mature and reliable, it has several problems, including environmental pollution, high noise, high maintenance costs, and dependence on fossil fuels. In particular, with the increasing awareness of environmental protection worldwide and the increasingly stringent emission standards for ships by the International Maritime Organization (IMO), the limitations of these traditional generators have become particularly prominent.

[0003] In addition to power supply, fresh water supply on board is equally important. Ocean-going ships especially need an effective water making system to meet the crew's water needs for living and the cooling and cleaning water of machinery and equipment.

[0060] In some embodiments, the water storage device 1, the purified water pool 2 and the dosing tank 3 are all provided with a drainage pipe 701. This facilitates the rapid removal of residual water and impurities in the system, reduces the maintenance time and cost of the system, improves the maintenance and cleaning efficiency of the system, and also reduces the risk of failure of the system due to blockage or contamination.

[0064] In addition, the utility model also provides a boat with both power generation and water making functions, which is applied to a marine fuel cell system. The boat includes:

[0065] The main deck 801, the second deck 802 and the third deck 803 are arranged in order from top to bottom;

[0066] The fuel supply device 901 is arranged on the main deck 801; the hydrogen fuel cell 902 is arranged on the second deck 802; the water storage device 1, the purification device, the dosing tank 3 and the disinfection device are all arranged on the third deck 803;

[0067] The first water pipe 4 is connected to various daily water devices on the main deck 801 to meet daily water needs; the second water pipe 6 is connected to the crew living cabin area 904 on the main deck 801 to meet emergency drinking water needs.

[0068] In the above embodiment, the fuel supply device 901 is specifically arranged in the cabin of the aft bridge building at the rear of the main deck. First, this area is far away from the living area, which is very safe for personnel and equipment on board; second, this area is relatively open, which is conducive to the safe release of hydrogen due to safety accidents; finally, this area is located above the aft deck, which is convenient for the filling and replenishment of hydrogen. It should be noted that during the safety period, all hydrogen pipelines must be double-walled pipes, and the outer pipelines are forced ventilated to ensure the safety of the hydrogen pipelines.

[0069] In order to facilitate and ensure the safety of the arrangement of various supporting systems such as hydrogen, air, and water and heat management, the hydrogen fuel cell 902 is arranged in a closed cabin on the second deck 802. The closed cabin needs to pay attention to the division of safety zones, the fire-fighting and life-saving equipment needs to be arranged in accordance with relevant regulations, and explosion-proof ventilation equipment needs to be arranged and installed for forced ventilation. The hydrogen supply pipeline in this area can pass through the main deck 801 and the second deck 802 through the cabin penetration to provide "fuel" for the hydrogen fuel cell 902, and the oxygen (air) supply can be provided by the air compressor arranged on the second deck 802 through the air vents of the ship's air supply duct to provide oxygen (air) for the marine fuel cell system.

[0072] In special circumstances, the second water pipe 6 transports water to the crew living cabin area 904 for emergency drinking water in special circumstances such as lack of fresh water supply and major ship accidents.

[0073] By rationally allocating the locations of components such as the fuel supply device, hydrogen fuel cells, and water storage devices, the space utilization of the boat is optimized, while ensuring the convenient supply of daily and emergency water, thereby improving the overall performance and living comfort of the boat.

[0074] It should be noted that the power output direction can be adjusted according to the power generation of the marine fuel cell system. If the power generation capacity of the marine fuel cell system is moderate and limited, it can be used only to replace the emergency power generation system for emergency power supply; if the power generation capacity of the marine fuel cell system is small, it can be used only to charge the marine batteries on the ship; it can also be used to replace the shore power for power supply when the ship is docked.

[0075] Accordingly, if the amount of water produced by the electrochemical reaction of the marine fuel cell system is sufficient, part of it can be directly supplied to the daily water needs of the ship, and another part can be provided to the ship's power plant, boiler water replenishment, deck rust removal and other industrial water, and the remaining part can be used for emergency water in special circumstances of the ship after being treated by the dosing system and ultraviolet disinfection system. If the amount of water produced by the electrochemical reaction of the marine fuel cell system is small, it can only be used for emergency drinking water in special circumstances of the ship.

[0076] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0077] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
