Abstract

The invention relates to a method and a device for the signature-free discharging of the submarine waste gas that is produced in energy converters in conjunction with the generation of electric energy. Said waste gas is guided by pressure into a pipeline through which water from outside the vessel flows. The resulting gas bubbles are reduced by static mixers which are located inside the pipeline through which water is flowing. The strong turbulence in the liquid causes the gas to dissolve. Since the waste gas is dissolved inside the submarine, no localizable gas bubbles appear outside of the vessel. The working pressure for the method is the same as the submerging pressure, which means that energy consumption is low.

Dieses Abgas muss an Bord gelagert oder aus dem Fahrzeug verbracht werden. Bekannte Lösungen hierfür sind Watermanagement-Systeme, Verflüssigung des Abgases und anschließende Lagerung oder die direkte Ausbringung als Gas.Energy converters, which are used to generate electricity independent of the outside air on submersibles, use hydrocarbons as an energy source to produce not only electricity but also exhaust gas. This exhaust gas must be stored on board or taken out of the vehicle. Known solutions for this are water management systems, liquefaction of the exhaust gas and subsequent storage or direct application as a gas.

Zur CO^-Entsorgung von Unterwasserfahrzeugen soll Druckwasser von Außenbord in dasFor example, a device for the CO * disposal of underwater vehicles is known from EP 0 752 565 B1. For the CO ^ disposal of underwater vehicles pressurized water from the outboard into the
Unterwasserfahrzeug genommen werden, um dort mit einem Absorber CO* zu lösen und anschließend soll dieses Wasser, mit dem gelösten CO*, gegen den Tauchdruck wieder nach außen abgegeben werden. Danach ist eine Vorrichtung vorgesehen, die ein Gehäuse mit einer kreisförmigen Innenlauffläche für einen rotierenden Kurvenkörper aufweist, wobei dieBe taken underwater to dissolve CO * with an absorber and then this water, with the dissolved CO *, should be released to the outside against the diving pressure.

In Schiff & Hafen/Seewirtschaft, Heft 7/1992, S.43-46 wird im Beitrag „Der Kreislaufdiesel als außenluftunabhängiger Antrieb für Uboote" ein Water - Management- System beschrieben, das geeignet ist, Seewasser für die Absorber aufzunehmen und wieder nach außen abzugeben. Dieses Water - Management - System arbeitet durch Nutzung der Energie des unter Tauchdruck stehenden Seewassers. Die Anordnung besteht aus Steuerventilen und frei beweglichen Kolben, die einen tauchtiefen-unabhängigen Betrieb des Kreislaufdieselsystems ermöglichen. Die Förderpumpen für den Seewassereintritt brauchen nur die Rohrleitungswiderstände und Armaturwiderstände zu kompensieren.In Schiff & Hafen / Seewirtschaft, Issue 7/1992, pp.43-46, the article "The circulating diesel as a propulsion system for submarines that is independent of the outside air" describes a water management system that is suitable for absorbing seawater for the absorbers and back to the outside This water management system works by using the energy of the submerged sea water. The arrangement consists of control valves and freely movable pistons, which enable a depth-independent operation of the circuit diesel system. The feed pumps for the sea water entry only need the pipe resistances and valve resistances to compensate.

Die Aufgabe der Erfindung ist es daher, mit geringem Platz- und Energieaufwand, das Abgas signaturarm aus dem Fahrzeug zu bringen.The object of the invention is therefore to bring the exhaust gas signature-poor out of the vehicle with little space and energy.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale der Ansprüche 1 und 7 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den zugehörigen Ansprüchen 2 bis 6 beziehungsweise 8 bis 10 enthalten.According to the invention, this object is achieved by the features of claims 1 and 7. Advantageous developments of the invention are contained in the associated claims 2 to 6 and 8 to 10.
Demnach beinhaltet die Erfindung ein Verfahren zum signaturfreien Ausbringen von Abgas aus Unterwasserfahrzeugen, welches in Energiewandlern neben der Erzeugung von Elektroenergie anfällt, wobei das Abgas durch Druck in eine Rohrstrecke geleitet wird, welche von Außenbordwasser durchströmt wird. Die dabei entstehenden Gasblasen werden durch innerhalb der wasserdurchströmten Rohrstrecke angeordnete statische Mischer zerkleinert, wobei durch eine hohe Turbulenz der Flüssigkeit eine Auflösung des Gases erreicht wird. Durch die Auflösung des Abgases innerhalb des Unterwasserfahrzeuges treten außerhalb des Bootes keine zu ortenden Gasblasen auf. Da der Arbeitsdruck des Verfahrens gleich dem Tauchdruck ist, wird nur wenig Energie verbraucht.Accordingly, the invention includes a method for the signature-free discharge of exhaust gas from underwater vehicles, which occurs in energy converters in addition to the generation of electrical energy, the exhaust gas being conducted by pressure into a pipe section through which outboard water flows. The resulting gas bubbles are comminuted by static mixers arranged within the pipe section through which water flows, a dissolution of the gas being achieved by a high turbulence of the liquid. Due to the dissolution of the exhaust gas inside the underwater vehicle, there are no gas bubbles to be located outside the boat. Since the working pressure of the process is equal to the immersion pressure, little energy is used.
Nach einem bevorzugten Merkmal der Erfindung wird das Abgas über einen porösen Körper in die Rohrstrecke eingeleitet , wobei das Abgas vorzugsweise unter einem über dem Tauchdruck liegenden Druck in die Rohrstrecke eingebracht wird.According to a preferred feature of the invention, the exhaust gas is introduced into the pipe section via a porous body, wherein the exhaust gas is preferably introduced into the pipe section at a pressure above the diving pressure.
Die Rohrstrecke wird dabei über eine Pumpe mit Außenbordwasser (Seewasser) versorgt. Nach einem besonderen Merkmal wird die Rohrstrecke durch die Fahrt des Unterwasserfahrzeuges mit Außenbordwasser (Seewasser) versorgt, wobei zwischen dem Einlass- und Auslasspunkt für das Außenbordwasser Tauchdruck herrscht. Die Strömungsgeschwindigkeit des Wassers innerhalb der Rohrstrecke beträgt nach einem anderen Merkmal vorzugsweise 1 -3 m/s.The pipe section is supplied with outboard water (sea water) via a pump. According to a special feature, the pipe section is supplied with outboard water (seawater) by the movement of the underwater vehicle, with submersion pressure prevailing between the inlet and outlet points for the outboard water. According to another characteristic, the flow velocity of the water within the pipe section is preferably 1-3 m / s.
Die Erfindung beinhaltet auch eine Vorrichtung zum signaturfreien Ausbringen von Abgas aus Unterwasserfahrzeugen, weiches in Energiewandlern neben der Erzeugung von Elektroenergie anfällt. Im Unterwasserfahrzeug ist dazu mindestens eine Rohrstrecke angeordnet, welche einen Einlass für Außenbordwasser (Seewasser), einen Auslass für das im Wasser gelöste Abgas und eine Rohrimpfstelle für das in die Rohrstrecke einzuleitende Abgas aufweist. Innerhalb der Rohrstrecke ist mindestens ein statischer Mischer vorgesehen. Nach einem weiteren Merkmal ist im Bereich des Einlasses für das Außenbordwasser der Rohrstrecke eine Pumpe angeordnet. Die Impfstelle besteht nach einem besonderen Merkmal der Erfindung aus einem 90° Rohrbogenstutzen mit Impflanze und einem porösen Körper: Die Länge der Rohrstrecke ist nach einem bevorzugten Merkmal der Erfindung so ausgeführt, dass diese eine vollständige Auflösung der Gasblasen des Abgases erlaubt. Die Erfindung soll nachfolgend anhand der Figuren an einem Ausführungsbeispiel näher erläutert werden. Es zeigen:The invention also includes a device for the signature-free discharge of exhaust gas from underwater vehicles, which occurs in energy converters in addition to the generation of electrical energy. For this purpose, at least one pipe section is arranged in the underwater vehicle, which has an inlet for outboard water (sea water), an outlet for the exhaust gas dissolved in the water and a pipe inoculation point for the exhaust gas to be introduced into the pipe section. At least one static mixer is provided within the pipe section. According to a further feature, a pump is arranged in the area of the inlet for the outboard water of the pipe section. According to a special feature of the invention, the injection point consists of a 90 ° pipe elbow with a seedling and a porous body: According to a preferred feature of the invention, the length of the pipe section is such that it allows the gas bubbles in the exhaust gas to dissolve completely. The invention will be explained in more detail below with reference to the figures using an exemplary embodiment. Show it:
Figur 1 : Außenluftunabhängige Energieversorgung, Figur 2: Vorrichtung zur Ausbringung des Abgases.Figure 1: Outside air independent energy supply, Figure 2: Device for discharging the exhaust gas.
Bei einem Energiewandlersystem III zur Erzeugung von elektrischer Energie auf einem Unterwasserfahrzeug, welches mit Sauerstoff a aus einer Flüssiglagerung I und einem Kohlenwasserstoff b aus einem Tank II versorgt wird, entsteht neben elektrischer Energie und Wärme durch Reaktion des Kohlenwasserstoffes mit dem Sauerstoff ein Abgas c, welches neben Wasser vor allem aus Kohlendioxid besteht. Dieses Abgas wird in der Vorrichtung IV gemäß dem Verfahren nach Anspruch 1 in Wasser gelöst und außenbords gegeben.In an energy converter system III for generating electrical energy on an underwater vehicle, which is supplied with oxygen a from a liquid storage I and a hydrocarbon b from a tank II, in addition to electrical energy and heat, an exhaust gas c is produced by reaction of the hydrocarbon with the oxygen, which in addition to water consists primarily of carbon dioxide. This exhaust gas is dissolved in water in device IV according to the method of claim 1 and given outboard.
Hierzu wird eine Rohrstrecke 2 mittels einer Pumpe 4 oder durch die Fahrt des Fahrzeugs mit Seewasser vom Einlass A zum Auslass B durchströmt. Zweckmäßige Strömungsgeschwindigkeiten liegen im Bereich zwischen 1 und 3 m/s. An Ein- und Auslass herrscht dabei der Tauchdruck. Das Abgas C wird unter einem, über dem Tauchdruck liegenden Druck durch einen porösen Körper 1 innerhalb dieser Rohrleitung ausgebracht. Ein ausreichender Druck wird hierbei durch ein geeignetes Verfahren im Energiewandler III oder einen Verdichter im Abgasstrom c erreicht. Die Menge des Seewassers wird so bestimmt, dass das Wasser aufgrund seines Lösungsvermögens für Gase das Abgas komplett lösen kann. Die notwendige Menge des Wassers hängt dabei von der Zusammensetzung des Abgases, der Wassertemperatur und dem Tauchdruck ab. Durch Einsetzen der statischen Mischer 3 im Rohr 2 wird erreicht, dass sich aus dem Gas C sehr kleine Blasen bilden (< 3 mm), die durch die mittels der Mischer erzeugte hohe Turbulenz daran gehindert werden, sich zu größeren Blasen zu vereinigen. Durch die hohe Turbulenz und eine ausreichende Rohrlänge von beispielsweise ca. 30 m wird erreicht, dass sich die Blasen innerhalb des Rohres vollständig auflösen. Daher tritt an der Stelle B kein Gas mehr aus, welches zu orten wäre. For this purpose, a pipe section 2 is flowed through by a pump 4 or by the vehicle traveling with sea water from inlet A to outlet B. Appropriate flow velocities are in the range between 1 and 3 m / s. The diving pressure prevails at the inlet and outlet. The exhaust gas C is discharged under a pressure above the immersion pressure through a porous body 1 within this pipeline. Adequate pressure is achieved here by a suitable method in energy converter III or a compressor in exhaust gas stream c. The amount of seawater is determined so that the water can completely dissolve the exhaust gas due to its ability to dissolve gases. The amount of water required depends on the composition of the exhaust gas, the water temperature and the diving pressure. By inserting the static mixers 3 in the tube 2 it is achieved that very small bubbles form from the gas C (<3 mm), which are prevented from combining into larger bubbles by the high turbulence generated by the mixers. Due to the high turbulence and a sufficient pipe length of approx. 30 m, for example, the bubbles inside the pipe are completely dissolved. Therefore, at point B, there is no longer any gas that would be located.
