[0021] Beneficial effects of the present invention:

[0022] This ship water system includes a living fresh water tank, a technical fresh water tank, a desalination device and a distilled water tank. Fresh water is pre-stored in the living fresh water tank, which is connected to the first pressure tank to transport fresh water to the living area water supply system and the cabin area water supply system; fresh water is pre-stored in the technical fresh water tank, which is connected to the second pressure tank to transport fresh water to the cargo hold area water supply system and the equipment water supply system; the desalination device can collect seawater and desalinate it into fresh water; the desalination device is connected to the distilled water tank, and the fresh water produced by the desalination device is stored in the distilled water tank, which can be isolated from or connected to the second pressure tank.

[0023] Before going to sea, the living fresh water tank and the technical fresh water tank are pre-filled with fresh water for use during navigation. This fresh water comes from the port, does not contain radioactive substances, and can be used with confidence; the living fresh water tank is connected to the first pressure tank to transport fresh water to the living area water supply system and the engine room area water supply system to meet the living water needs of the crew in the living area and the engine room area, and at the same time meet the water needs of washing the upper deck; the technical fresh water tank is connected to the second pressure tank to transport fresh water to the cargo hold area water supply system and the equipment water supply system to meet the water needs of the engine room equipment and the deck equipment, and at the same time meet the water needs of washing the deck in the cargo hold area; the distilled water tank is used to store the fresh water made by the desalination device.

[0031] Ocean-going ships are usually equipped with water systems, which desalinate seawater into fresh water to meet the water needs of the crew's daily life and the operation of ship equipment. The water system in the prior art includes a fresh water tank and a fresh water pressure cabinet. The fresh water tank has a fresh water generator to desalinate seawater into fresh water. The fresh water tank supplies water to the fresh water pressure cabinet, which in turn supplies water to various parts of the entire ship that need water. However, the water system used in the prior art can only remove the salt in the seawater, resulting in radioactive substances in the fresh water supplied by the fresh water pressure cabinet. When the crew directly or indirectly contacts the water, the radioactive substances contained therein will affect their health.

[0032] To solve the above problems, Figure 1As shown, this embodiment provides a ship water system, which includes a living fresh water tank 1, a technical fresh water tank 3, a desalination device 5 and a distilled water tank 6. Fresh water is pre-stored in the living fresh water tank 1, and the living fresh water tank 1 is connected to the first pressure tank 2 to transport fresh water to the living area water supply system 71 and the cabin area water supply system 72; fresh water is pre-stored in the technical fresh water tank 3, and the technical fresh water tank 3 is connected to the second pressure tank 4 to transport fresh water to the cargo hold area water supply system 73 and the equipment water supply system 74; the desalination device 5 can collect seawater and desalinate seawater into fresh water; the desalination device 5 is connected to the distilled water tank 6, and the fresh water produced by the desalination device 5 is stored in the distilled water tank 6, and the distilled water tank 6 can be isolated from or connected to the second pressure tank 4.

[0033] Before going to sea, the living fresh water tank 1 and the technical fresh water tank 3 are pre-filled with fresh water for use during navigation. This fresh water comes from the port, does not contain radioactive substances, and can be used with confidence; the living fresh water tank 1 is connected to the first pressure tank 2 to transport fresh water to the living area water supply system 71 and the engine room area water supply system 72 to meet the living water needs of the crew in the living area and the engine room area, and at the same time meet the water needs for washing the upper deck; the technical fresh water tank 3 is connected to the second pressure tank 4 to transport fresh water to the cargo hold area water supply system 73 and the equipment water supply system 74 to meet the water needs of the engine room equipment and the deck equipment, and at the same time meet the water needs for washing the deck in the cargo hold area; the distilled water tank 6 is used to store the fresh water made by the desalination device 5. This fresh water is nuclear fresh water. Under normal circumstances, the distilled water tank 6 is isolated from the second pressure tank 4. When the fresh water in the technical fresh water tank 3 cannot be supplied, the distilled water tank 6 is connected to the second pressure tank 4, and the nuclear fresh water in the distilled water tank 6 is used to meet the water needs of the engine room equipment, the deck equipment, and the cargo hold area deck. Since the crew has a small range of activities in the cargo hold area and the nuclear-containing fresh water in the equipment has little impact on the outside world, at this time, the appropriate use of nuclear-containing fresh water for supply will not cause serious damage to the health of the crew. By pre-storing fresh water without radioactive substances, the basic living water needs of the crew during the voyage and the basic technical water needs of the ship are ensured. In the case of depletion of fresh water, the nuclear-containing fresh water produced by the desalination device 5 can be used for emergency water supply to the technical fresh water tank 3, ensuring the normal operation of the ship's equipment, while not causing pollution to the living fresh water tank 1, ensuring that the area where the crew often moves will not be exposed to radioactive substances.

[0034] Specifically, a connecting pipeline is provided between the domestic fresh water tank 1 and the technical fresh water tank 3, and a normally closed valve is provided on the connecting pipeline. Under normal circumstances, the normally closed valve cuts off the connecting pipeline, so that domestic water and technical water are supplied by two independent fresh water tanks; when encountering an emergency situation that endangers the safety of the ship, opening the normally closed valve can allow water between the domestic fresh water tank 1 and the technical fresh water tank 3 to circulate, preventing the water level in the domestic fresh water tank 1 from drying up and causing the basic life of the crew to be unable to be guaranteed.

[0035] Specifically, Figure 1 As shown, an ultraviolet sterilizer 81 is provided between the first pressure tank 2 and the living area water supply system 71, and the ultraviolet sterilizer 81 is used to sterilize the fresh water delivered by the living fresh water tank 1. The ultraviolet sterilizer 81 is used to kill microorganisms in the fresh water, ensure the safety of the fresh water quality supplied to the living area, and provide safe and reliable living water guarantee for the crew.

[0036] Specifically, Figure 1 As shown, a softening device 82 is provided between the second pressure tank 4 and the equipment water supply system 74, and the softening device 82 is used to soften the fresh water delivered by the technical fresh water tank 3. The softening device 82 removes hard substances in the fresh water to make the water softer, reduce the loss of the equipment, and prevent the hard substances from forming deposits inside the equipment.

[0037] Specifically, Figure 1 As shown, the technical fresh water tank 3 is connected to the fire water supply system 75, and the technical fresh water tank 3 can transport fresh water to the fire water supply system 75. Using the fresh water in the technical fresh water tank 3 to extinguish the fire can ensure that no radioactive substances will remain on the ship during the fire extinguishing, thereby ensuring the health of the crew.

[0038] However, the fresh water in the technical fresh water tank 3 is limited. In the case of a serious fire, the fresh water capacity in the technical fresh water tank 3 cannot meet the fire extinguishing needs. In order to ensure the first priority of fire extinguishing, in this embodiment, the fire water supply system 75 is also connected to the seawater main, and the seawater main can transport seawater to the fire water supply system 75. In the specific implementation process, the fresh water in the technical fresh water tank 3 is first used to supply the fire water supply system 75 for about 15 minutes. If the fire is still not under control, the seawater main is used to transport seawater to the fire water supply system 75 to continue extinguishing the fire, so as to ensure that the fire is extinguished in time.

[0039] Specifically, the fire water supply system 75 includes a water outlet pipe in the living area, and the technical fresh water tank 3 is connected to the water outlet pipe in the living area, and the technical fresh water tank 3 can transport fresh water to the water outlet pipe in the living area. When a fire occurs, the water used for extinguishing the fire in the living area comes entirely from the technical fresh water tank 3, and no radioactive substances will remain in the living area, thereby ensuring the safety of the living area after the fire is extinguished.

[0040] Specifically, the fire water supply system 75 also includes a water outlet pipe in the engine room area and a water outlet pipe in the cargo hold area. The seawater main pipe is connected to the water outlet pipe in the engine room area and the water outlet pipe in the cargo hold area. The seawater main pipe can transport seawater to the water outlet pipe in the engine room area and the water outlet pipe in the cargo hold area. When a fire occurs, the water used to extinguish the fire in the engine room area and the cargo hold area is completely seawater. Since the crew will not move too much there, even if there are residual radioactive substances in the engine room area and the cargo hold area, it will not have too much impact on the crew.

[0041] In this embodiment, the ship water system also includes a storage room, which is used to store drinking water. By setting up the storage room, a large amount of drinking water can be stored on board in advance to ensure the water demand during the voyage. Other beverages, such as milk, can also be stored in the storage room.

[0042] The present embodiment also provides a ship, including the ship water system as above, which ensures the basic living water needs of the crew during navigation and the basic technical water needs of the ship by pre-storing fresh water that does not contain radioactive substances. When the fresh water is exhausted, the nuclear-containing fresh water produced by the desalination device 5 can be used to provide emergency water supply to the technical fresh water tank 3, thereby ensuring the normal operation of the ship's equipment. At the same time, it will not cause pollution to the living fresh water tank 1, ensuring that the area where the crew often moves will not be exposed to radioactive substances.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
