Description
Technical Field
The invention belongs to the technical field of ships, and particularly relates to a top side tank ballast water mechanical energy recycling and utilizing system.
Background
Currently, the types of ships become more diverse as cargo transportation is required, and cargo ships include various types such as a grocery ship, a bulk carrier, a container ship, a ro-ro ship, a barge, a tanker, a liquefied gas ship, a refrigerator ship, and the like. Due to the special characteristics of bulk carrier transportation, the bulk carrier mostly travels without load during return, such as a mineral sand carrier in the bulk carrier, and since the produced mineral sand only exists near a loading port, the mineral sand carrier usually does not load goods when arriving at an unloading port and returning, i.e. travels without load. However, a certain amount of draft is required to be maintained during normal navigation of the ship, so that the phenomenon that the center of gravity of the ship is too high and the ship is prone to overturn is avoided, and meanwhile, the draft of the ship is also used for ensuring that a propeller behind the ship is always below the horizontal plane and the phenomenon of 'galloping' does not occur, so that the ship needs to be driven into seawater with a certain weight to maintain the draft, and the seawater is called 'ballast water', so that the ballast water is an important guarantee for safe, stable and efficient navigation of the ship.
The ballast water is in the ballast tank of the ship, on some bulk cargo ships, the ballast tank of the ship is divided into a top side tank and a bottom side tank, wherein the top side tank is higher, the height of the top side tank from the horizontal plane can reach about 20m when the large bulk cargo ship sails in an idle state, and the ship needs to consume a large amount of energy when driving the ballast water into the top side tank, namely, before the ship reaches a cargo port to discharge the ballast water of the top side tank, a large amount of available mechanical energy is contained in the ballast water in the top side tank.
Although the presence of ship ballast water ensures the safety of ship navigation, the ocean-going ship has a long route, a long distance between the loading port and the unloading port, and a large difference between the types of organisms in the sea areas, so that if ballast water carried from the unloading port is directly discharged into a water area near the loading port, a large amount of organisms contained in the ballast water may affect or even extinguish the organisms in the discharged water area. For this reason, the international maritime organization requires that the ship be provided with a ballast water treatment apparatus for treating the ballast water at the time of loading and discharging the ballast water.
At present, ballast water treatment methods on ships are various, wherein ultraviolet treatment of ballast water has the advantages of simple treatment method, no toxic or side effect, no adverse effect on ship pipelines, pump bodies and ship cabin coatings and the like, and is widely applied to ballast water treatment. However, in the ballast water treatment process, the higher the ultraviolet irradiation degree is, the better the sterilization effect is, so in the ballast water treatment system, in order to achieve a better treatment effect, the power of the ultraviolet lamp tube can reach hundreds of kilowatts, and a large amount of precious ship electric energy can be consumed.
Therefore, if the mechanical energy in the ballast water can be recovered and used for supplying electric energy to the ultraviolet lamp tube when the ballast water in the top side tank is discharged from the ship, the method has a greater practical significance and also conforms to the theme of 'green shipping' nowadays.
