Description

Vorrichtung zum Speichern und Transportieren von kryogen verflüssigten GasenDevice for storing and transporting cryogenically liquefied gases
Die Erfindung bezieht sich auf eine Vorrichtung zum Speichern und Transportieren von kryogen verflüssigten Gasen mit einem thermisch isolierten Behälter , der von Rohrleitungen, insbesondere Beschickungs- und Entnahmeleitungen und ggf. Messleitungen durchsetzt ist und einen Mantel bzw. eine Ummantelung aufweist.The invention relates to a device for storing and transporting cryogenically liquefied gases with a thermally insulated container, which is interspersed with piping, in particular feed and withdrawal lines and possibly measuring lines and having a jacket or a sheath.
Konventionelle thermisch isolierte Behälter sind üblicherweise als doppelwandige Kessel ausgebildet, wobei die doppelwandige Mantelstruktur zu evakuieren ist, so dass ein bleibendes Vakuum in diesem Zwischenraum bzw. Mantel herrscht. Neben einem Füllrohr und Einrichtungen für entsprechende Füllstandsanzeigen ist bei derartigen Behältern auch ein Entnahmerohr vorzusehen, wobei in aller Regel entweder die flüssige Phase, die Gasphase oder beide Phasen entnommen werden und ein entsprechender Druck im Inneren des Kessels aufgebaut wird, um das Flüssiggas oder dessen Gasphase auszupressen.Conventional thermally insulated containers are usually designed as double-walled vessels, wherein the double-walled shell structure is to be evacuated, so that a permanent vacuum prevails in this space or jacket. In addition to a filling tube and facilities for corresponding level indicators is in such containers also provide a sampling tube, which usually either the liquid phase, the gas phase or both phases are removed and a corresponding pressure is built up inside the boiler to the liquefied petroleum gas or its gas phase squeeze.
Besonders kritische Stellen an derartigen Tanks sind die Stellen, an welchen Leitungen durch den doppelwandigen Mantel bzw. die Ummantelung hindurch geführt werden, wobei hier insbesondere neben dem Umstand, dass hier mit beiden Wänden Schweißverbindungen nötig sind, auch der Umstand berücksichtigt werden muss, dass in diesem Bereich hohe Temperaturwechselbeanspruchungen vorliegen, welche hohe mechanische Beanspruchungen im Bereich der Schweißnähte zufolge haben. Bedingt durch die Konstruktion konventioneller Tanks sind Beeinträchtigungen, wie bspw. Haarrisse an einer Schweißnaht überaus kritisch, da sie die Funktion des gesamten Behälters beeinträchtigen. Ein erneutes Evakuieren zum Aufbau eines bleibenden Vakuums ist ausgeschlossen, so dass der Zwischenraum ein wärmetragendes Medium (z.B. Luft) aufnehmen kann. Bei konventionellen Tanks wurden darüber hinaus einige der Leitungen im evakuierten Mantelraum installiert, wodurch wiederum eine Wärmezufuhr zu der in den Rohren stehenden Flüssigkeit oder dem Gas von außen begünstigt wird.Particularly critical points on such tanks are the points at which lines are passed through the double-walled jacket or the sheath, in which case in addition to the fact that here with both walls welded joints are needed, the fact must be taken into account that in This area high thermal cycling are present, which have high mechanical stresses in the welds. Due to the construction of conventional tanks, impairments such as hairline cracks on a weld are extremely critical because they affect the function of the entire container. A renewed evacuation to build a permanent vacuum is excluded, so that the space can accommodate a heat-carrying medium (eg air). In conventional tanks, moreover, some of the pipes have been installed in the evacuated shell space, which in turn promotes heat input to the liquid or gas inside the pipes from the outside.
Die Erfindung zielt nun darauf ab, einen Tank der eingangs genannten Art zu schaffen, welcher auch bei Schadhaftwerden von Teilen des Mantels bzw. der Ummantelung seine thermischen Isolationseigenschaften im Wesentlichen beibehält und bei welchem bei besonders günstiger Herstellung diese schadhaften Stellen durch neue ersetzbar sind, so dass die Isolierwirkung über den gesamten Umfang des Behälters wieder hergestellt wird.The invention now aims to provide a tank of the type mentioned above, which also in Schadhaftwerden of parts of the shell or the jacket essentially retains its thermal insulation properties and in which at particularly favorable production these defective locations are replaced by new, so that the insulating effect over the entire circumference of the container is restored.
Die Erfindung zielt weiters darauf ab, die entsprechenden Leitungen und insbesondere die Rohrleitungen für das Füllen und die Entnahme sowie die Messleitungen zu einer möglichst kompakten Baueinheit zusammen zu fassen, und diese nicht wie bisher an unterschiedlichen Stellen zu platzieren, sondern möglichst rohrbündelähnlich ausschließlich in dem Behälter zu verlegen, so dass sich thermodynamische Vorteile und weitereThe invention further aims to put together the corresponding lines and in particular the piping for filling and removal and the test leads to a compact unit as possible, and not place them as before at different locations, but possible tubular bundle similar exclusively in the container to relocate, so that has thermodynamic benefits and more

Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Vor- richtung der eingangs genannten Art im Wesentlichen darin, dass der Mantel bzw. die Ummantelung von zumindest teilweise evakuierten doppelwandigen Paneelen gebildet ist. Die den isolierenden Mantel bildenden Paneele haben die thermischenTo achieve this object, the device according to the invention of the type mentioned initially consists essentially in that the jacket or the jacket is formed by at least partially evacuated double-walled panels. The panels forming the insulating jacket have the thermal
Eigenschaften eines konventionellen, vakuumisolierten Mantels. Durch die erfindungsgemäße Ausbildung wird die Möglichkeit geschaffen, die thermische Isolation modular aufzubauen, wobei die Paneele unabhängig von einander ausgetauscht werden können und dabei die überwiegende Isolierwirkung des Behälters erhalten bleibt. Wärmebrücken sind bei der erfindungsgemäßen Ausbildung theoretisch an den einander zugewandten Stoßfugen der Paneele denkbar. Dieser Wärmeverlust kann aber dadurch nachhaltig vermindert werden, dass der Mantel von wenigstens zwei Lagen doppelwandiger Paneele gebildet wird, welche dann einander überlappend angeordnet werden können, so dass jeweils eine Lage der Paneele über Stoßfugen zu liegen kommt und diese abdeckt.Properties of a conventional, vacuum-insulated jacket. The inventive construction, the possibility is created to construct the thermal insulation modular, the panels can be replaced independently of each other while the predominant insulating effect of the container is maintained. Thermal bridges are in the inventive design theoretically conceivable on the facing joints of the panels. But this heat loss can be sustained reduced by the fact that the mantle of at least two layers of double-walled panels is formed, which can then be arranged overlapping each other, so that in each case one layer of the panels comes to lie over butt joints and covers them.
Mit Vorteil ist die erfindungsgemäße Ausbildung daher so getroffen, dass der Mantel vorzugsweise zweilagig ausgebildet ist, wobei die Paneele einer Lage die Stoßfugen der Paneele einer anderen Lage überdecken.Advantageously, the inventive construction is therefore made such that the jacket is preferably formed in two layers, wherein the panels of one layer cover the butt joints of the panels another position.
Um Verletzungen beispielsweise beim Transport zu vermeiden und Witterungseinflüsse fern zu halten wird der isolierende Mantel in vorteilhafter Weise durch einen weiteren, ausschließlich auf die schützende Funktion ausgerichteten Wetterschutzmantel ge- schützt.In order to avoid injuries during transport, for example, and to keep out the effects of weathering, the insulating jacket is advantageously protected by a further weatherproof jacket which is oriented exclusively to the protective function.
Prinzipiell lassen sich derartige Speicher- und Transporttanks in relativ großen Dimensionen fertigen, wobei gerade bei großen Speicher- und Transporttanks bei konventioneller Bauweise die Gefahr von Haarrissen in einer der Wände des Mantels besonders hoch ist und die Evakuierung des gesamten Mantels eine besondere technische Herausforderung darstellt. Dies gilt insbesondere für die Stellen der Durchführung von Rohr- oder Messleitungen und für Stellen, die weit vom Ursprung des anliegenden Vakuums entfernt sind.In principle, such storage and transport tanks can be produced in relatively large dimensions, with the danger of hairline cracks in one of the walls of the shell being particularly high, especially in the case of large storage and transport tanks of conventional construction, and the evacuation of the entire jacket presents a special technical challenge. This applies in particular to the points of passage of pipe or measuring lines and to points which are far away from the origin of the applied vacuum.
Bevorzugt wird diese Gefahr dadurch hintangehalten, dass die Rohr- und ggf. Armatur- und Messleitungen durch eine im wesentlichen axiale Durchbrechung des Mantels in das innere des Behälters geführt sind und dass die Rohr- und ggf. Armatur- und Messleitungen im Bereich der Durchbrechung mit wärmeisolierendem Material umgeben sind, wobei das wärmeisolierende Material die Durchbrechung vollständig verschließt und je nach Länge des dadurch gebildeten Stopfens den Wärmedämmwert des Isoliermantels erreichen kann oder sogar übersteigen kann. In bevorzugter Weise entspricht der Wärmewiderstand des isolierenden Mantels dem des Stopfens. Auf diese Weise wird eine kompakte Einheit von Rohr- und Messleitungen geschaffen, die durch lediglich eine axiale Durchbrechung des Mantels geführt werden, so dass die Möglichkeit gegeben ist, diese eine im Wesentlichen axiale Durchbrechung entsprechend zu isolieren, um erforderlichenfalls die gesamte Rohr- und Messleitungen tragende Baueinheit aus dem Tank auszubauen und eine neue einzubauen.Preferably, this risk is obstructed by the fact that the pipe and possibly fitting and measuring lines are guided by a substantially axial opening of the shell in the interior of the container and that the pipe and possibly fitting and measuring lines in the region of the opening heat-insulating material are surrounded, wherein the heat-insulating material completely closes the opening and depending on the length of the stopper formed thereby can reach or even exceed the thermal insulation value of the insulating jacket. Preferably, the thermal resistance of the insulating jacket corresponds to that of the plug. In this way, a compact unit of pipe and measuring lines is provided, which are guided by only one axial opening of the shell, so that there is the possibility to isolate this one substantially axial opening accordingly, if necessary, the entire pipe and measuring lines remove supporting unit from the tank and install a new one.
Um Wärmeübertragungen im Bereich der Stützfüße in der Betriebslage zu vermeiden, ist die Ausbildung mit Vorteil so getroffen, dass Abstützelemente nicht mit dem eigentlichen Behälter direkt verbunden sind, sondern an der Außenwand der doppelwandigen Paneele festgelegt sind.In order to avoid heat transfer in the area of the support feet in the operating position, the training is advantageously made so that support elements are not directly connected to the actual container, but are fixed to the outer wall of the double-walled panels.
Die axiale Durchbrechung für die Durchführung von Rohr- und gegebenenfalls Messleitungen ist mit Vorteil im Bereich des Bodens des Behälters angeordnet, so dass in der Betriebsläge ein entsprechendes Messgerätemodul unmittelbar und ohne be- sonderen Montageaufwand angeschlossen werden kann.The axial opening for the passage of pipe and optionally measuring lines is advantageously arranged in the region of the bottom of the container, so that in the Betriebsläge a corresponding meter module can be connected directly and without special installation effort.
Prinzipiell wird ein derartiger Speicherbehälter für kryogen verflüssigte Gase im erforderlichen Fall für den Transport gekippt, da die axiale Länge derartiger Behälter relativ groß sein und ohne weiteres mehrere Meter übersteigen kann. Um hier eine sichere Transportposition einnehmen zu können, kann der Behälter ein entsprechendes Transportlager nahe der Achse des Behälters aufweisen, welches in eine entsprechende Lagerschale des Transportfahrzeuges eingebracht werden kann.In principle, such a storage container for cryogenically liquefied gases is tilted in the required case for transport, since the axial length of such containers can be relatively large and easily exceed several meters. In order to be able to assume a safe transport position, the container may have a corresponding transport bearing near the axis of the container, which can be introduced into a corresponding bearing shell of the transport vehicle.
Zu diesem Zweck ist die Ausbildung mit Vorteil so getroffen, dass eine feuchte- und wärmeisolierende, abnehmbare Kappe ein oberes Transportlager umschließt. Nach dem Aufstellen des Speicherbehälters und dem Verschwenken aus dem Transportlager in eine im wesentlichen vertikale Position kann dieses Transportlager durch diese abnehmbare Kappe in wärmeiso- lierender Weise abgeschlossen werden. Die Widerlager zum oberen Transportlager befinden sich in geeigneter Weise am unteren Teil des Tanks.For this purpose, the training is advantageously made so that a moisture and heat-insulating, removable cap encloses an upper transport bearing. After placing the storage container and the pivoting from the transport storage in a substantially vertical position of this transport storage can be completed by this removable cap in a heat-insulating manner. The abutments to the upper Transport bearings are conveniently located at the bottom of the tank.
Um die durch Temperaturunterschiede und Temperaturspannungen entstehenden Kräfte sicher aufnehmen zu können und um die Behälterwand von derartigen Kräften im Wesentlichen freihalten zu können, ist die Ausbildung mit Vorteil so getroffen, dass die Rohr- und ggf. Messleitungen an der der im wesentlichen axialen Durchbrechung gegenüberliegenden Seite nachgiebig festgelegt sind. Auf diese Weise wird an der der axialen Durchbrechung gegenüber liegenden Seite im Inneren des Speicher- und Transportbehälters ein entsprechender Dehnungsausgleich geschaffen, so dass die Isolation im Bereich der axialen Durchbrechung von übermäßigen Kräften entlastet wird.In order to safely absorb the forces resulting from temperature differences and temperature stresses and to keep the container wall substantially free of such forces, the training is advantageously made so that the pipe and possibly measuring lines on the opposite side of the substantially axial aperture are determined resilient. In this way, a corresponding expansion compensation is created on the side opposite the axial opening in the interior of the storage and transport container, so that the insulation is relieved of excessive forces in the region of the axial opening.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert.The invention will be explained in more detail with reference to an embodiment schematically illustrated in the drawing.
In der Zeichnung ist mit 1 ein Tank für verflüssigte Gase bezeichnet, welcher mit vakuumisolierten Paneelen 2 verkleidet ist, welche in zwei Lagen aufgebracht sind, wobei die zweite Lage die Stoßfugen der ersten Lage verdeckt. Der Tank 1 weist eine in axialer Richtung verlaufende Durchbrechung 3 auf , durch welche die Rohrleitungen 4 in den Tank eintauchen.
