Die Erfindung betrifft eine Anordnung, bestehend aus einem Druckspeicher für ein gasförmiges oder flüssiges Medium und einem Verbraucher, dem gasförmiges oder flüssiges Medium aus dem Druckspeicher über eine Verbindungsleitung zuführbar ist.The invention relates to an arrangement consisting of a pressure accumulator for a gaseous or liquid medium and a consumer, the gaseous or liquid medium from the pressure accumulator via a connecting line can be fed.
Gattungsgemäße Anordnungen, bestehend aus Druckspeicher, Verbraucher und Verbindungsleitung, kommen beispielsweise bei mobilen Kleinbetankungsanlagen, insbesondere Kleinbetankungsanlagen für gasförmigen Wasserstoff, zur Anwendung. Stand der Technik ist es, Druckspeicher, die mittlerweile bis zu einem Speicherdruck von 850 bar ausgelegt werden, mittels Abreisskupplungen und/oder mechanischen Schnellschlussventilen mit der mobilen Kleinbetankungsanlage zu verbinden. Darüber hinaus sind bei Zapfsäulen, die der Betankung mit "kritischen" Medien, wie beispielsweise Erdgas, Wasserstoff, etc. dienen, Abreissicherungen vorgesehen, die im Falle einer Belastung der Zapfsäule eine sicherheitstechnische Abschaltung gewährleisten müssen.Generic arrangements, consisting of pressure accumulator, consumer and connecting line, are used for example in mobile small refueling systems, especially small refueling systems for gaseous hydrogen. State of the art is to connect pressure accumulator, which are now designed to a storage pressure of 850 bar, by means of tear-off couplings and / or mechanical quick-closing valves with the mobile small refueling system. In addition, at petrol pumps, which serve the refueling with "critical" media, such as natural gas, hydrogen, etc., Abreissicherungen provided that have to ensure a safety shutdown in the event of a load on the pump.
Die zwischen dem Druckspeicher und dem Verbraucher vorzusehende Rohr- oder Schlauchverbindung muss - entsprechend ihrem Anwendungszweck - nationalen bzw. internationalen Sicherheitsvorschriften entsprechen. Dies macht eine entsprechende Werkstoffwahl für die vorzusehende Rohr- bzw. Schlauchverbindung erforderlich. Insbesondere bei einer Auslegung für sehr hohe Drücke und/oder der Verwendung von "kritischen" Medien wie beispielsweise Erdgas oder Wasserstoff - Stichwort "Wasserstoff-Versprödung" -, führt dies dazu, dass die vorzusehende Rohr- bzw. Schlauchverbindung sehr teuer ist.The pipe or hose connection to be provided between the pressure accumulator and the consumer must comply with national or international safety regulations, according to its intended purpose. This makes a suitable choice of material for the pipe or hose connection to be provided required. In particular, in a design for very high pressures and / or the use of "critical" media such as natural gas or hydrogen - keyword "hydrogen embrittlement" -, this means that the proposed pipe or hose connection is very expensive.
Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Anordnung, bestehend aus einem Druckspeicher für ein gasförmiges oder flüssiges Medium und einem Verbraucher, dem gasförmiges oder flüssiges Medium aus dem Druckspeicher über eine Verbindungsleitung zuführbar ist, anzugeben, die die vorgenannten Nachteile vermeidet. Zur Lösung dieser Aufgabe wird eine gattungsgemäße Anordnung vorgeschlagen, die dadurch gekennzeichnet ist, dass die Verbindungsleitung einen Rohrwendelbereich und ein Not-Aus-Ventil aufweist und parallel zu der Verbindungsleitung eine Pneumatik-Leitung angeordnet ist, wobei diese derart mit dem Not-Aus-Ventil in Wirkverbindung steht, dass bei einem Bruch der Pneumatik-Leitung das Not-Aus-Ventil schließt.Object of the present invention is to provide a generic arrangement consisting of a pressure accumulator for a gaseous or liquid medium and a consumer, the gaseous or liquid medium from the pressure accumulator via a connecting line can be supplied, which avoids the aforementioned disadvantages. To solve this problem, a generic arrangement is proposed, which is characterized in that the connecting line has a coiled tubing area and an emergency stop valve and parallel to the connecting line, a pneumatic line is arranged, which in this way with the emergency stop valve is in operative connection that closes at a fraction of the pneumatic line, the emergency stop valve.
Weitere vorteilhafte Ausgestaltungen der erfindungsgemäßen Anordnung sind dadurch gekennzeichnet ist, dassFurther advantageous embodiments of the arrangement according to the invention are characterized in that
der Druckspeicher wenigstens eine Gasflasche, ein mobiler Tank oder einthe accumulator at least a gas cylinder, a mobile tank or a
Betankungsfahrzeug ist,Refueling vehicle,
der Druckspeicher für einen Speicherdruck bis zu 2000 bar ausgelegt ist,the accumulator is designed for a storage pressure up to 2000 bar,
der Verbraucher eine Betankungsanlage, insbesondere eine mobile Betankungsanlage, oder eine Versorgungseinheit ist, undthe consumer is a refueling system, in particular a mobile refueling system, or a supply unit, and
das Not-Aus-Ventil in unmittelbarer Nähe zum Druckspeicher angeordnet ist.the emergency stop valve is located in close proximity to the pressure accumulator.
Die erfindungsgemäße Anordnung sowie weitere Ausgestaltungen derselben, die Gegenstände der abhängigen Patentansprüche darstellen, seien im Folgenden anhand des in der Figur dargestellten Ausführungsbeispieles näher erläutert.The arrangement according to the invention as well as further embodiments thereof, which constitute subjects of the dependent claims, will be explained in more detail below with reference to the embodiment shown in the figure.
Die Figur zeigt in schematisierter Form einen Druckspeicher S, bei dem es sich vorzugsweise um einen Drucktank, ein Betankungsfahrzeug oder einen mobilen Tank handelt. Dargestellt ist des Weiteren in Form einer Black-Box ein Verbraucher V, bei dem es sich beispielsweise um eine mobile Kleinbetankungsanlage für flüssigen und/oder gasförmigen Wasserstoff handelt.The figure shows in schematized form an accumulator S, which is preferably a pressure tank, a refueling vehicle or a mobile tank. Also shown in the form of a black box is a consumer V, which is, for example, a mobile small refueling system for liquid and / or gaseous hydrogen.
Unter Druck stehender, flüssiger und/oder gasförmiger Wasserstoff aus dem Druckspeicher S wird dem Verbraucher V über die Verbindungsleitung 1 zugeführt. Erfindungsgemäß weist die Verbindungsleitung 1 nunmehr einen Rohrwendelbereich 2 auf. Dieser Rohrwendelbereich 2 ermöglicht im Falle einer mechanischen Zugbelastung auf die Verbindungsleitung 1 ein Verlängern bzw. Strecken der Verbindungsleitung 1. Derartige Rohrwendelbereiche 2 sind vorzugsweise mäander- oder spiralförmig ausgebildet.Under pressure, liquid and / or gaseous hydrogen from the pressure accumulator S is supplied to the consumer V via the connecting line 1. According to the invention, the connecting line 1 now has a coiled tube region 2. In the case of a mechanical tensile load on the connecting line 1, this coiled tubing region 2 makes it possible to extend or extend the connection Connecting pipe 1. Such coiled tubing regions 2 are preferably formed meandering or spiral.
Erfindungsgemäß weist die Verbindungsleitung 1 zudem ein Not-Aus-Ventil 3 auf, das vorzugsweise in unmittelbarer Nähe zum Druckspeicher S angeordnet ist.According to the invention, the connecting line 1 also has an emergency-off valve 3, which is preferably arranged in the immediate vicinity of the pressure accumulator S.
Des Weiteren ist parallel oder im Wesentlichen parallel zu der Verbindungsleitung 1 erfindungsgemäß eine Pneumatik-Leitung 4 vorgesehen.Furthermore, according to the invention, a pneumatic line 4 is provided parallel or substantially parallel to the connecting line 1.
Druckspeicher S sowie Verbraucher V werden so zueinander angeordnet, dass die Verbindungsleitung 1 eine definierte Länge, beispielsweise 3 Meter, "überbrücken" muss; aufgrund des Vorsehens des Rohrwendelbereiches 2 beträgt die Länge der Verbindungsleitung 1 mehr als 3 Meter.Pressure accumulator S and consumer V are arranged to each other so that the connecting line 1 a defined length, for example, 3 meters, must "bridge" must; due to the provision of the coiled tubing region 2, the length of the connecting line 1 is more than 3 meters.
Die vorzusehende Pneumatik-Leitung 4 wird nun auf die vorgenannte definierte Länge ausgelegt. Wirkt eine mechanische Zugbelastung auf die Verbindung zwischen dem Druckspeicher S und dem Verbraucher V kommt es bei einer Überschreitung der Bruchgrenze der Pneumatik-Leitung 4 zu einem Bruch derselben. Aufgrund des durch den Rohrwendelbereich 2 gegebenen Längenunterschiedes zwischen der Verbindungsleitung 1 und der Pneumatik-Leitung 4 erfolgt immer zuerst ein Bruch der Pneumatik-Leitung 4, bevor ggf. bei anhaltender mechanischer Zugbelastung ein Bruch der Verbindungsleitung 1 erfolgt.The pneumatic line 4 to be provided is now designed for the aforementioned defined length. If a mechanical tensile load acts on the connection between the pressure accumulator S and the consumer V, the fracture limit of the pneumatic line 4 will be exceeded if the fracture limit is exceeded. Due to the difference in length between the connecting line 1 and the pneumatic line 4 given by the coiled tubing region 2, a break in the pneumatic line 4 always occurs first, possibly leading to a break in the connecting line 1 when the mechanical tensile load is maintained.
Die Pneumatik-Leitung 4 steht jedoch erfindungsgemäß mit dem Not-Aus- Ventil 3 derart in Wirkverbindung - dargestellt durch die punktierte Leitung 5 -, dass bei einem Bruch der Pneumatik-Leitung 4 das Not-Aus-Ventil 3 sofort schließt. In vorteilhafter Weise ist die Wirkverbindung dergestalt ausgebildet, dass ein sofortiges und vollständiges Schließen des Not-Aus-Ventiles 3 realisiert werden kann. Dadurch ist gewährleistet, dass nach dem Bruch der Pneumatik-Leitung 4 aus dem Druckspeicher S kein weiteres Medium über die Verbindungsleitung 1 abströmen und damit bei einem (zeitlich verzögerten) Bruch der Verbindungsleitung 1 in die Umgebung gelangen kann.However, the pneumatic line 4 is according to the invention with the emergency-off valve 3 in operative connection - represented by the dotted line 5 - that at a fraction of the pneumatic line 4, the emergency-off valve 3 closes immediately. Advantageously, the operative connection is designed such that an immediate and complete closing of the emergency-off valve 3 can be realized. This ensures that after the breakage of the pneumatic line 4 from the accumulator S no further medium via the connecting line 1 to flow and thus in a (delayed in time) breakage of the connecting line 1 can get into the environment.
Mittels der erfindungsgemäßen Anordnung wird eine sicherheitstechnisch unbedenkliche Lösung geschaffen, die zum einen keine Werkstoffproblematik besitzt und zum anderen relativ kostengünstig realisiert werden kann. By means of the arrangement according to the invention, a safety-friendly solution is created which, on the one hand, has no material problem and, on the other hand, can be realized relatively inexpensively.
