In order to explain the present invention more clearly, a preferred embodiment is given in conjunction with the drawings in detail as follows. Please refer to FIG. 1, which is a ship 100 according to an embodiment of the present invention, which includes a hull 10 and a ballast water generating system. The ballast water generating system includes an extraction device 20, a distilled water generating device 30, and A ballast tank 40. in:

The extraction device 20 is installed on the hull 10 to extract water. For example, the extraction device 20 may include a pump for pumping the water body of the ship 100 in the sailing water area, where the water body may include, but is not limited to, river water, lake water or sea water depending on the sailing water area. For example, in this embodiment, the ship 100 is sailing on the ocean, and the extraction device 20 can be used to extract seawater for use.

The distilled water generating device 30 is installed on the hull 10 and connected to the extraction device 20 to receive the water body extracted by the extraction device 20 for distillation treatment to form distilled water. In addition, in one embodiment, a cooling device (not shown in the figure) can also be provided to connect between the distilled water generator 30 and the extraction device 20.

The heat exchanger exchanges heat between the above-mentioned equipment and the power system, thereby cooling the above-mentioned equipment and the power system, and can also recover and reuse the waste heat generated by the above-mentioned equipment and power system. For example, in one embodiment, the cooling device is connected to a fresh water cooler matched with a power system in the hull 10, and cools the fresh water cooling water of the fresh water cooler by conveying cold sea water, that is, to cool the fresh water cooler. The sea water exchanges heat with the high-temperature fresh water cooling water of the fresh water cooler, and the fresh water cooler cools the power system to dissipate the waste heat generated by the power system. At the same time, the waste heat can also be used to heat the sea water. In addition, the heated seawater can be used by the distilled water generator 30, so as to recover and reuse the waste heat generated by the ship and reduce the energy consumption of the distilled water generator 30. Wherein, in an embodiment, the power system may include, but is not limited to, a diesel engine.

For example, in one embodiment, it is assumed that the working temperature of the distilled water generator 30 is between 50°C and 85°C, then Before the seawater is delivered to the distilled water generating device 30, it is preferable to control the temperature of the heated seawater to not exceed 85°C, so as to maintain the stability of the water generating process or the distillation process. In addition, if the temperature of the seawater in the conveying pipeline is too high, it may be that part of the seawater has begun to vaporize in the pipeline, and there is a potential risk of pipeline bursting. Therefore, in practice, it is Or the subsequent seawater temperature control is actually one of the considerations required for the stability and safety of the overall system.

In addition, in one embodiment, the distilled water generator can use SASAKURA's model VA-100, but it is not limited to this. For other applications, other types of distilled water generators can also be used.

The advantage between ～1 is that it can keep the ship 100 sailing under proper load conditions to obtain good propulsion efficiency. In other words, while the ship continues to consume fuel every day, it also replenishes an appropriate amount of distilled water to the pressure. In the water tank, the amount of distilled water that is better to make up should not exceed the fuel consumption, so as to avoid overloading the hull and reducing sailing efficiency. In addition, in other practical applications, fuel consumption, water production, and water injection can also be non-quantitative designs, which are not limited to the above description.
