Embodiment Construction

[0050] figure 1A system 10 is shown configured as a conventional piping and pumping system for circulating ballast water to ballast tanks 1 on board. Ballast tanks 1 are generally arranged along the periphery of the vessel, and each ballast tank 1 is provided with a ballast water distribution pipe 5 from the main supply line. The distribution pipe 5 is provided with an appropriate number of valves 6 .

[0051] The system 10 may be used to supply ballast water to and discharge ballast water from the ballast tank 1 .

[0052] figure 2 An embodiment of the present invention is shown in which the recirculation system 20 supplements figure 1 A conventional ballast water pumping system 10 as described in . The recirculation system 20 consists of a recirculation pump 22 and pipes communicating with the ballast tank 1 and the nitrogen generator 21 .

[0053] Ballast water is pumped out of ballast tank 1 by recirculation pump 22 via return pipe 23 to return pipe 24 and returned t...

Abstract

The invention discloses a system for treating ballast water in a ballast tank (1) on a ship or in an offshore structure, the system (20) comprising: one or more ballast tanks (1), circulating a pump (22) capable of circulating or recirculating ballast water from and to said one or more ballast tanks through piping; a nitrogen and / or carbon dioxide generator (21 ), It is connected to the pipeline (22) in such a way that nitrogen and / or carbon dioxide can be supplied to the ballast water; and one or more nozzle heads (28) are functionally connected to The pipes are also arranged in one or more ballast tanks (1), the one or more nozzle heads comprising nozzles for injecting air-laden water into the one or more ballast tanks (1) at least one nozzle (34); and wherein at least one nozzle (34) is configured to be drivable to rotate about first and second axes simultaneously, wherein said second axis is perpendicular or non-perpendicular to said first axis, to form a 3D mixer pattern.

Description

technical field [0001] The present invention relates to a system for treating ballast water in ballast tanks on ships or in offshore construction, said system comprising: [0002] one or more ballast tanks; a circulating pump that circulates or recirculates ballast water from and to said one or more ballast tanks through piping; nitrogen and / or carbon dioxide generation a device connected to the pipeline in such a way that the nitrogen and / or carbon dioxide can be supplied to the ballast water; and [0003] one or more nozzle heads functionally connected to the duct and arranged in one or more ballast tanks, the one or more nozzle heads including a At least one nozzle in the tank that sprays gas-laden water. [0004] According to other aspects of the invention, it relates to a vessel as claimed in claims 7-9. Background technique [0005] In order to maintain the stability of the ship independent of whether it is carrying cargo, depending on the nature of the cargo, the s...
