Embodiment Construction

[0050] figure 1A system 10 is shown configured as a conventional piping and pumping system for circulating ballast water to the ballast tanks 1 on board the ship. Ballast tanks 1 are usually arranged along the periphery of the ship 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 can be used to supply ballast water to the ballast tank and to discharge ballast water from the ballast tank 1 .

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

[0053] The ballast water is pumped out of the ballast tank 1 by the recirculation pump 22 via the retur...

Abstract

A system for treating ballast water in ballast tanks (1) onboard vessels is disclosed. The system (20) comprises: one or more ballast tanks (1); a circulation pump (22) circulating or recirculating, via a tubing, ballast water from and to the one or more ballast tanks (1); a nitrogen and / or carbon dioxide generator (21) which is connected to the tubing (22) on the delivery side of the recirculation pump (22) in such a manner that nitrogen and / or carbon dioxide can be supplied to the ballast water; and one or more nozzle heads (28) that are functionally connected to the tubing and is / are arranged in one or more ballast tanks (1), wherein the one or more nozzle heads comprises at least one nozzle (34) for injection of the gas-containing water into the one or more ballast tanks (1); the at least one nozzle (34) is configured for powered rotation about both a first axis and a second axis; and the second axis is perpendicular or not perpendicular to the first axis to the effect that a three-dimensional mixer pattern is produced.

Description

technical field [0001] The present invention relates to a system for treating ballast water in ballast tanks on ships or in offshore structures, said system comprising: [0002] One or more ballast tanks; circulation pumps that circulate or recirculate ballast water from and to the 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, which are functionally connected to the pipeline and are arranged in one or more ballast tanks, said one or more nozzle heads comprising means for supplying said one or more ballast tanks At least one nozzle spraying air-entrained water in the tank. [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 ...
