Vorrichtung zum Abblasen von GasenDevice for blowing off gases

Die Erfindung betrifft eine Vorrichtung zum Abblasen von Gas, aufweisend eine Leitung, über die das abzublasende Gas geführt wird. Ferner betrifft die Erfindung ein Speichercompartment, insbesondere einen Speicherbehälter zum Speichern von Gasen und/oder verflüssigten Gasen, aufweisend wenigstens eine Vorrichtung zum Abblasen von Gas.The invention relates to a device for blowing off gas, comprising a conduit through which the gas to be discharged is guided. Furthermore, the invention relates to a storage compartment, in particular a storage container for storing gases and / or liquefied gases, comprising at least one device for blowing off gas.

Gattungsgemäße Vorrichtungen zum Abblasen von Gas kommen bspw. bei Flüssigwasserstoff-Speicherbehältem bzw. -Tanks zur Anwendung. Die derzeitige Ausblasung von (gasförmigem) Wasserstoff an derartigen Tanks führt jedoch zu Problemen. Aufgrund der "Ausblasegeometrie" erfolgt eine horizontale Ausblasung. Dabei kommt es durch ein vorgesetztes Prallblech zu einer örtlichen Verwirbelung und Wasserkondensation aus der Luft.Generic devices for blowing off gas are used, for example, in liquid hydrogen storage containers or tanks. The current blow-out of (gaseous) hydrogen at such tanks, however, leads to problems. Due to the "blow-out geometry" a horizontal blow-out occurs. It comes through a superior baffle to a local turbulence and water condensation from the air.

Bei ungünstigen Witterungs- und Windverhältnissen können unerwünschte "Schwergaswolken" entstehen und diese nach unten gedrückt werden. Aus diesem Grund sind Ex-Zonen und Sicherheitsbereiche zu berücksichtigen, die eine Aufstellung derartiger Tanks in der Nähe öffentlicher Bereiche, wie bspw. an bzw. in Tankstellen, Wohngegenden, Straßen usw., zumindest in Frage stellen.In unfavorable weather and wind conditions unwanted "heavy gas clouds" can arise and these are pressed down. For this reason, it is necessary to take into account ex-zones and safety areas which at least call into question the installation of such tanks in the vicinity of public areas, such as at petrol stations, residential areas, roads, etc.

Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Vorrichtung zum Abblasen von Gas, aufweisend eine Leitung, über die das abzublasende Gas geführt wird, anzugeben, die die vorgenannten Nachteile vermeidet.Object of the present invention is to provide a generic device for blowing off gas, comprising a conduit through which the gas to be discharged is performed, which avoids the aforementioned disadvantages.

Zur Lösung dieser Aufgabe wird eine gattungsgemäße Vorrichtung zum Abblasen von Gas, aufweisend eine Leitung, über die das abzublasende Gas geführt wird, vorgeschlagen, die dadurch gekennzeichnet, dass die Leitung wenigstens einen Bereich aufweist, der in Form eines Venturirohres ausgebildet ist.To solve this problem, a generic device for blowing off gas, comprising a conduit through which the gas to be discharged is guided, proposed, which is characterized in that the conduit has at least one region which is formed in the form of a Venturi tube.

Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Vorrichtung zum Abblasen von Gas, die Gegenstände der abhängigen Patentansprüche sind, sind dadurch gekennzeichnet, dass die Leitung wenigstens einen Bereich aufweist, der im Wesentlichen horizontal verläuft und der in Form eines Venturirohres ausgebildet ist,Further advantageous embodiments of the device according to the invention for blowing off gas, which are the subject of the dependent claims, are characterized in that the conduit has at least one region which extends essentially horizontally and which is designed in the form of a Venturi tube,

- die Leitung wenigstens einen Wasserablauf aufweist,- The line has at least one water outlet,

der oder wenigstens einer der Wasserabläufe im Bereich des Venturirohres angeordnet ist,the or at least one of the water drains is arranged in the area of the Venturi tube,

- Mittel zur Beheizung der Leitung vorgesehen sind und- means for heating the line are provided and

die Austrittsöffnung der Leitung ein Gitter aufweist.the outlet opening of the conduit has a grid.

Die erfindungsgemäße Vorrichtung zum Abblasen von Gas sowie weitere Ausgestaltungen derselben, die Gegenstände der abhängigen Patentansprüche darstellen, seien im Folgenden anhand des in der Figur dargestellten Ausführungsbeispieles näher erläutert.The device according to the invention for blowing off gas as well as further embodiments of the same, which constitute objects of the dependent claims, will be explained in more detail below with reference to the embodiment shown in the figure.

Die Figur zeigt eine schematisierte Darstellung einer möglichen Ausführungsform der erfindungsgemäßen Vorrichtung 1 zum Abblasen von Gas. Diese besteht aus einem im Wesentlichen vertikal angeordneten Leitungsbereich 2, über den das abzublasende Gas nach oben geführt wird - dargestellt durch den Pfeil. In der Figur nicht dargestellt ist das Speichercompartment bzw. der Speicherbehälter, aus dem das abzublasende Gas entnommen wird. Unter dem Begriff "Speichercompartment" seien alle bekannten Möglichkeiten zur Speicherung von Gasen oder Flüssigkeiten zu verstehen.The figure shows a schematic representation of a possible embodiment of the device 1 according to the invention for blowing off gas. This consists of a substantially vertically arranged line region 2, via which the gas to be discharged is guided upward - represented by the arrow. Not shown in the figure is the storage compartment or the storage container from which the gas to be discharged is taken. The term "storage compartment" is to be understood as meaning all known possibilities for storing gases or liquids.

Nach einer Umlenkung geht die Abblaseleitung in einen im Wesentlichen horizontal angeordneten Leitungsbereich 3 über. Dieser ist nunmehr erfindungsgemäß in Form eines Venturirohres 4 ausgebildet. Die dadurch angesaugte (Umgebungs)Luft - dargestellt durch den Pfeil 5 - vermischt sich innerhalb des Venturirohres 4 mit dem abzublasenden Gas. Diese Ansaugöffnung der Venturidüse dient - neben einem weiteren Wasserablauf 9, auf den im Folgenden noch eingegangen wird - darüber hinaus als größerer Wasserablauf, der insbesondere bei Schwallwasser, verursacht bspw. durch Wolkenbrüche, von Vorteil ist. Nach einer erneuten Umlenkung geht die Abblaseleitung wieder in einen im Wesentlichen vertikal angeordneten Leitungsbereich 6 über. An dessen Austrittsende ist vorzugsweise ein Gitter 7 vorgesehen.After a deflection, the blow-off line merges into a substantially horizontally arranged line region 3. This is now formed according to the invention in the form of a Venturi 4. The thereby sucked (ambient) air - represented by the arrow 5 - mixes within the Venturi tube 4 with the gas to be blown off. This intake opening of the Venturi nozzle serves - in addition to a further water outlet 9, which will be discussed in the following - moreover, as a larger water drain, which is particularly advantageous in the case of splash water, caused, for example, by cloudbursts. After another redirection, the blow-off line returns to a substantially vertically arranged line region 6. At its outlet end, a grid 7 is preferably provided.

Aufgrund der vorbeschriebenen Konstruktion erfährt das abzublasende Gas im Bereich des Venturirohres 4 eine Beschleunigung und Durchmischung mit Luft. Es ist hierbei nicht zwingend erforderlich, dass der in Form eines Venturirohres 4 ausgebildete Leitungsbereich horizontal angeordnet ist. Vielmehr ist auch eine nicht horizontale Anordnung denkbar.Due to the above-described construction, the gas to be discharged experiences an acceleration and mixing with air in the area of the venturi 4. In this case, it is not absolutely necessary for the line region formed in the form of a Venturi tube 4 to be arranged horizontally. Rather, a non-horizontal arrangement is conceivable.

Die in der Figur dargestellte Konstruktion weist darüber hinaus den Vorteil auf, dass Regenwasser, das über die Öffnung in die Abblasleitung eingedrungen ist, über das Venturirohr 4 abfließen kann. Das unerwünschte Eindringen von Regenwasser in den Leitungsbereich 2 kann dadurch wirkungsvoll verhindert werden.The construction shown in the figure also has the advantage that rainwater that has penetrated through the opening in the blow-off, can flow through the venturi 4. The unwanted ingress of rainwater into the line region 2 can be effectively prevented.

Wird die erfindungsgemäße Vorrichtung zum Abblasen von Wasserstoff aus einem Flüssigwasserstoff-Speicherbehälter verwendet, kommt bei geringen Wasserstoffmengen, wie sie bspw. als Rückgas bei einer Fahrzeugbetankung anfallen, der Venturieffekt nicht voll zum Tragen. Aufgrund der geringen Mengen an abzublasendem Wasserstoff und einer damit zwangsläufig verbundenen Anwärmung im Kamin und Austausch mit Luft am Austritt der Abblasleitung ergibt sich nur der übliche kleine Ex-Bereich, wie in den Ex-Richtlinien dargestellt.If the device according to the invention is used to blow off hydrogen from a liquid hydrogen storage container, the venturi effect does not fully take effect at low hydrogen quantities, such as those incurred as back gas during vehicle refueling. Due to the small amounts of abzublasendem hydrogen and thus inevitably associated warming in the fireplace and exchange with air at the outlet of the discharge line results in only the usual small Ex-area, as shown in the Ex-directives.

Beim Ausblasen großer Wasserstoffmengen hingegen, wie sie bspw. bei der Betankung eines Flüssigwasserstoff-Speicherbehälters mit relativ "warmem" Wasserstoff, beim Abblasen der Hauptsicherheitsventile, beim Freispülen eines Speicherbehälters für Wartungen, usw. auftreten, kommen folgende Vorteile der erfindungsgemäßen Vorrichtung zum Abblasen von Gas zum Tragen:When blowing large amounts of hydrogen, however, as they occur, for example. When refueling a liquid hydrogen storage tank with relatively "warm" hydrogen when blowing the main safety valves, when flushing a storage tank for maintenance, etc., the following advantages of the device according to the invention for blowing off gas to carry:

- Aufgrund des Venturieffekts wird der ausblasende Wasserstoff sofort mit- Due to the Venturi effect of the Ausblasende hydrogen immediately with

Luft vermischt, der Wasserstoff wir dadurch noch im Venturirohr auf wesentlich höhere Temperaturen angewärmt. Durch die zusätzliche Luft wird der Massenstrom wesentlich erhöht, beschleunigt und durch die dem Bereich des Venturirohres nachgeschaltete vertikale Umlenkung senkrecht mit hoher Geschwindigkeit ausgeblasen.Air mixed, the hydrogen we warmed thereby in Venturi tube to much higher temperatures. As a result of the additional air, the mass flow is substantially increased, accelerated and blown out vertically at high speed through the vertical deflection downstream of the area of the Venturi tube.

- Grundsätzlich ist eine senkrechte Ausblasung von Vorteil gegenüber einer waagrechten Ausblasung; der hohe Impuls der Ausströmung verhindert ein Absinken des Wasserstoffs unter die Ausblasehöhe des Kamins, gleichzeitig wird die Verwirbelung und Verdünnung mit der angesaugten Luft beschleunigt.- Basically, a vertical blow-out is advantageous over a horizontal blow-out; the high momentum of the outflow prevents the hydrogen from sinking below the discharge height of the chimney, at the same time accelerating the turbulence and dilution with the intake air.

- Aufgrund der in der Figur dargestellten Konstruktion und des Venturieffekts wird das abzublasende Gas in der Vertikalen beschleunigt, so dass auch bei ungünstigen Witterungsbedingungen ein sicheres Abblasen gewährleistet werden kann.- Due to the construction shown in the figure and the Venturi effect the gas to be discharged is accelerated in the vertical, so that even in adverse weather conditions a safe blowing can be guaranteed.

In vorteilhafter Weise weist die Abblasleitung wenigstens einen Wasserablauf 9 auf, wobei dieser vorzugsweise, wie in der Figur dargestellt, im Bereich des Venturirohres 4 angeordnet ist.In an advantageous manner, the discharge line has at least one water outlet 9, wherein this is preferably arranged in the region of the venturi 4, as shown in the figure.

Ein Schnee- und Vereisungsschutz erfolgt durch eine (elektrische) Anliegeheizung 8, die ebenfalls vorzugsweise im Bereich des Venturirohres 4 angeordnet ist. Im Regelfall wird es ausreichend sein, wenn diese eine Leistung bis 100 Watt aufweist. Einfallender Schnee wird mittels dieser Heizung 8 geschmolzen und kann sodann wie Regenwasser abfließen. Eine Vereisung kann wirkungsvoll verhindert werden, wenn der Bereich des Venturirohres 4 durch die Heizung 8 permanent auf einer Temperatur von mehr als 0 0C gehalten wird.Snow and ice protection is provided by an (electric) abutment heater 8, which is also preferably arranged in the region of the venturi 4. As a rule, it will be sufficient if this has a power of up to 100 watts. Incident snow is melted by means of this heater 8 and can then drain off like rainwater. An icing can be effectively prevented if the area of the Venturi 4 is kept permanently at a temperature of more than 0 ° C. by the heater 8.

Am Austritt bzw. an der Ausblasestelle ist vorzugsweise ein Gitter 7 vorgesehen. Dieses verhindert das Einnisten von Vögeln, Insekten u. ä.. Ablagerungen auf dem Gitteraufsatz 7 sind von unten sichtbar und könnten gegebenenfalls zügig entfernt werden.At the outlet or at the blow-out point preferably a grid 7 is provided. This prevents the nesting of birds, insects u. .. Deposits on the lattice tower 7 are visible from below and could be removed quickly if necessary.

Manche Speichercompartments bzw. -behälter weisen aus Sicherheitsgründe zwei oder mehr Vorrichtungen zum Abblasen von Gas auf. In derartigen Fällen ist es von besonderem Vorteil, wenn diese für unterschiedliche Gasdurchsätze ausgelegt sind. So sind bspw. im Falle eines Flüssigwasserstoff-Speicherbehälters im Regelfall zwei Abblasleitungen vorgesehen, wobei eine der Leitungen dem betriebsmäßigen Abbasen dient, während die andere Leitung als Sicherheitsabblasleitung fungiert. Letztere sollte für einen größeren Gasdurchsatz ausgelegt sein.For safety reasons, some storage compartments or containers have two or more devices for blowing off gas. In such cases, it is of particular advantage if they are designed for different gas flow rates. For example, in the case of a liquid hydrogen storage tank, two are usually used Blowdown provided, wherein one of the lines is the operational Abbasen, while the other line acts as Sicherheitsabblasleitung. The latter should be designed for a larger gas throughput.

Die erfindungsgemäße Vorrichtung zum Abblasen von Gas, insbesondere vonThe inventive device for blowing off gas, in particular of

Wasserstoff erhöht die Sicherheit an Flüssigwasserstoff-Speicherbehältern, da die Ex- und Sicherheitszonen auch bei sehr konservativer Betrachtung reduziert werden können. Zudem werden auch die Einflüsse ungünstiger Witterungs- und Windverhältnisse reduziert.Hydrogen increases the safety of liquid hydrogen storage tanks, as the hazardous and safety zones can be reduced even when very conservative. In addition, the effects of unfavorable weather and wind conditions are reduced.

Die Aufstellung von Speichercompartments bzw. -behältern ist nunmehr auch in der unmittelbaren Nähe von öffentlichen Einrichtungen möglich, ohne dass es der Installation zusätzlicher Schutzeinrichtungen, wie bspw. gasdichter Wände, bedarf.The installation of storage compartments or containers is now also possible in the immediate vicinity of public facilities, without the need for the installation of additional protection devices, such as gas-tight walls.

Es sei nochmals betont, dass der erfindungsgemäße Gedanke bei allen Gasen, insbesondere bei allen brennbaren Gasen, realisiert werden. It should again be emphasized that the idea according to the invention is implemented for all gases, in particular for all combustible gases.
