Abstract
Description
Die Erfindung betrifft einen Speicherbehälter, insbesondere für kryogene Medien, wie z. B. Wasserstoff, Helium, Stickstoff und LNG (Liquid Natural Gas).The invention relates to a storage container, in particular for cryogenic media, such as e.g. B. hydrogen, helium, nitrogen and LNG (Liquid Natural Gas).
Technische Gase, wie die obengenannten, werden zweckmäßigerweise in flüssiger, d. h. kryogener Form in Speicherbehältern transportiert und gelagert. Da der Transport sowie die Lagerung dieser Gase in der Regel unter Druck erfolgt, weisen die dafür verwendeten Speicherbehälter einen inneren Druckbehälter auf. Zwischen diesem Druckbehälter für das zu speichernde Medium und dem äußeren Behälter befindet sich ein Isolationsraum, der im Normalfall als Vakuumisolation ausgelegt ist.Technical gases, such as those mentioned above, are expediently in liquid, d. H. cryogenic form transported and stored in storage containers. Because the transport as well as the storage of these gases usually under pressure, they indicate this used an internal pressure vessel. Between this There is a pressure tank for the medium to be stored and the outer tank an isolation room that is normally designed as vacuum insulation.
Derartige Druck-Speicherbehälter mit ebenen Seitenflächen können jedoch aufgrund der sich ergebenden großen Wanddicken nicht wirtschaftlich hergestellt werden. Aus diesem Grunde sind der inneren Druckbehälter und somit der Speicherbehälter an sich in zylindrischer Bauweise ausgeführt.Such pressure storage tanks with flat side surfaces can, however, due to of the resulting large wall thicknesses cannot be produced economically. Out for this reason, the inner pressure tank and thus the storage tank itself executed in a cylindrical design.
In naher Zukunft werden Erdgas (LNG) und Wasserstoff in zunehmendem Maße als Kraftstoff für land- und nicht landgebundene Verkehrsmittel, wie z. B. Kfz′s, Schiffe, Flugzeuge, etc., verwendet werden. Da Druck-Speicherbehälter mit ebenen Seiten flächen aufgrund ihres hohen Gewichts, das aus den großen Wanddicken resultiert, in den genannten Verkehrsmitteln nicht oder nur schlecht eingesetzt werden können, werden bis heute ausschließlich zylindrische Speicherbehälter eingesetzt. Diese pas sen sich jedoch meist nur ungünstig an die Fahrzeuggeometrie an. Dadurch entsteht ein Lückenvolumen zwischen dem, um bei dem Beispiel des Kraftfahrzeuges zu blei ben, Fahrzeug und Speicherbehälter.In the near future, natural gas (LNG) and hydrogen will increasingly be considered Fuel for land and non land transport, such as B. vehicles, ships, Airplanes, etc., can be used. Because pressure storage tanks with flat sides due to their high weight, which results from the large wall thickness, in the means of transport mentioned cannot be used or can only be used poorly, To date, only cylindrical storage tanks are used. This pas However, they usually only adversely affect the vehicle geometry. This creates a gap volume between that to lead in the example of the automobile ben, vehicle and storage tank.
Aufgabe der vorliegenden Erfindung ist es, einen Speicherbehälter, insbesondere einen Speicherbehälter für kryogene Medien anzugeben, der es erlaubt, unerwünschte Lückenvolumina zu schließen. Des weiteren soll dieser Speicherbehälter, verglichen mit den bekannten zylindrischen Speicherbehältern, billiger in der Herstellung sein.The object of the present invention is a storage container, in particular a Specify storage containers for cryogenic media that allow unwanted To close gap volumes. Furthermore, this storage container should be compared with the known cylindrical storage containers, be cheaper to manufacture.
Dies wird erfindungsgemäß dadurch erreicht, daß der Speicherraum aus mehreren aufeinandergestapelten Formblechen im wesentlichen gleicher Größe und Form be steht, der Formblech-Stapel oben und unten von Deckblechen und an seinen Seiten von festeingebundenen Formstücken, sog. Sidebars, begrenzt ist und Mittel, die ein Kommunizieren der durch die Formbleche gebildeten Innenräume ermöglichen, vorge sehen sind.This is achieved according to the invention in that the storage space consists of several stacked shaped sheets be substantially the same size and shape stands, the stack of shaped sheets above and below of cover sheets and on its sides is bounded by permanently integrated fittings, so-called sidebars, and means that a Allow communication of the interiors formed by the shaped sheets, pre are seen.
Der erfindungsgemäße Speicherbehälter sowie weitere Ausgestaltungen davon sei anhand der Fig. 1 bis 5 näher erläutert.The storage container according to the invention and further configurations thereof will be explained in more detail with reference to FIGS. 1 to 5.
Fig. 1 zeigt den erfindungsgemäßen Speicherbehälter im Querschnitt, wie er insbe sondere für die Speicherung kryogener Medien oder für die wärmeverlustarme Speicherung von Medien unter hoher Temperatur verwendet wird. Fig. 1 shows the storage container according to the invention in cross section, as it is used in particular for the storage of cryogenic media or for the low heat loss storage of media at high temperature.
Dieser besteht aus einem äußeren Behälter 1 sowie dem eigentlichen druckstabilen Speicherraum für das zu speichernde Medium. Gemäß der Erfindung besteht der Speicherraum aus mehreren, aufeinandergestapelten Formblechen 5, wobei diese im wesentlichen die gleiche Größe bzw. Dimensionierung und Form aufweisen.This consists of an outer container 1 and the actual pressure-stable storage space for the medium to be stored. According to the invention, the storage space consists of a plurality of stacked shaped sheets 5 , these having essentially the same size or dimensioning and shape.
Die Formbleche 5 sind im Falle des dargestellten Speicherbehälters durch sog. Zwi schenbleche 4 voneinander getrennt. Gemäß der Erfindung wird der Formblechstapel auf seiner Ober- bzw. Unterseite durch ein oberes Deckblech 3 bzw. ein unteres Deck blech 3′ begrenzt. Seitlich werden die durch die Zwischenbleche 4 geschaffenen, mit Formblechen 5 ausgefüllten Räume, gemäß der Erfindung, durch festeingebundene Formstücke, sog. Sidebars 8, abgeschlossen.The shaped plates 5 are separated from each other in the case of the storage container shown by so-called intermediate plates 4 . According to the invention, the form sheet stack on its top and bottom by an upper cover plate 3 and a lower cover sheet 3 is limited '. Laterally, the spaces created by the intermediate plates 4 and filled with shaped plates 5 , according to the invention, are closed off by firmly integrated molded pieces, so-called sidebars 8 .
Sowohl die Zwischenbleche 4 als auch die Formbleche 5 weisen eine Vielzahl von Bohrungen oder Schlitze 6 auf, über die ein Kommunizieren der durch die Formbleche 5 und Zwischenbleche 4 gebildeten Innenräume bzw. Kammern ermöglicht wird.Both the intermediate plates 4 and the shaped plates 5 have a multiplicity of bores or slots 6 , via which communication of the interiors or chambers formed by the shaped plates 5 and intermediate plates 4 is made possible.
Das Befüllen und Entleeren des Speicherraumes erfolgt mittels einer oder gegebenen falls mehrerer Befüll- bzw. Entnahmeleitungen 7.The storage space is filled and emptied by means of one or, if appropriate, a plurality of filling or removal lines 7 .
Zwischen dem äußeren Behälter 1 und dem eigentlichen druckstabilen Speicherraum befindet sich der Isolationsraum 2. Dieser kann gegebenenfalls vakuumisoliert sein und/oder mit einem Isolationsmaterial, wie z. B. Perlit oder einer Multi-Layer-Isolation, gefüllt sein. Im Falle einer nichtisolierten Ausführung des Speicherbehälters können der äußere Behälter 1 sowie der Isolationsraum 2 entfallen. The insulation space 2 is located between the outer container 1 and the actual pressure-stable storage space. This can optionally be vacuum insulated and / or with an insulation material such as. B. perlite or a multi-layer insulation. In the case of a non-insulated design of the storage container, the outer container 1 and the insulation space 2 can be omitted.
Die Druckkräfte, die auf das obere und untere Deckblech 3 bzw. 3′ wirken, werden von den vertikalen Stegen der Formbleche 5 aufgenommen. Die Druckkräfte, die auf die festeingebundenen Formstücke, die sog. Sidebars 8, wirken, werden von den horizon tal angeordneten Zwischenblechen 4 aufgenommen.The compressive forces acting on the upper and lower cover plates 3 and 3 'are absorbed by the vertical webs of the shaped plates 5 . The compressive forces that act on the firmly integrated fittings, the so-called sidebars 8 , are absorbed by the horizon tal arranged intermediate plates 4 .
Fig. 2 zeigt eine Ausgestaltung des erfindungsgemäßen Speicherbehälter in einer explosionsartigen Darstellung. Hierbei ist auf die Darstellung der festeingebundenen Formstücke sowie des gegebenenfalls notwendigen äußeren Behälters und des Isolationsraumes verzichtet. Fig. 2 shows an embodiment of the storage container according to the invention in an exploded view. In this case, the representation of the permanently integrated molded pieces and the possibly necessary outer container and the insulation space is dispensed with.
Diese Ausgestaltung des erfindungsgemäßen Speicherbehälters verzichtet auf jegliche Zwischenbleche, d. h. die Formbleche 5 werden in einem Winkel von 90°C zueinander versetzt aufeinander gestapelt. Nach oben und unten werden sie durch ein oberes Deckblech 3 bzw. ein unteres Deckblech 3′ begrenzt.This embodiment of the storage container according to the invention dispenses with any intermediate plates, ie the shaped plates 5 are stacked on top of one another at an angle of 90 ° C. Up and down, they are limited by an upper cover plate 3 and a lower cover plate 3 '.
Wiederum sind Bohrungen oder Schlitze vorzusehen, über die ein Kommunizieren der durch die Formbleche 5 gebildeten Innenräume bzw. Kammern ermöglicht wird.Again, holes or slots are to be provided through which communication of the interior spaces or chambers formed by the shaped plates 5 is made possible.
Das Verbinden der einzelnen Formbleche miteinander kann z. B. durch Verlöten der aufeinanderliegenden Formblechflächen erfolgen.The connection of the individual shaped sheets together can, for. B. by soldering the Form sheet surfaces lying one on top of the other.
Fig. 3 zeigt ebenfalls einen Speicherbehälter gemäß der Erfindung im Querschnitt. Bei den folgenden Fig. 3, 4 und 5 wurde auf eine Darstellung des äußeren Behälters 1 sowie des Isolationsraumes 2 verzichtet. Fig. 3 also shows a storage container according to the invention in cross section. In the following FIGS. 3, 4 and 5, the outer container 1 and the insulation space 2 have been omitted.
Auch der in der Fig. 3 dargestellte Speicherraum weist keine Zwischenbleche auf, wie dies ebenfalls bei der in der Fig. 2 dargestellten Speicherraumkonstruktion der Fall ist. Die Formbleche 5 besitzen dichtaneinandergereihte kegelstumpfförmige Auswölbun gen, die durch Tiefziehen am ebenen Blech hergestellt werden. Die Formbleche werden gegensinnig gestapelt, so daß sich jeweils die Kleinkreise der Kegelstümpfe zweier Formbleche berühren; ebenso berühren sich die ebenen Blechflächen mit den Großkreisen der Kegelstümpfe, der sich daran anschließenden Formbleche.The storage space shown in FIG. 3 also has no intermediate plates, as is also the case with the storage space construction shown in FIG. 2. The shaped sheets 5 have closely aligned frustoconical Auswölbun conditions that are produced by deep drawing on the flat sheet. The shaped sheets are stacked in opposite directions so that the small circles of the truncated cones of two shaped sheets touch each other; Likewise, the flat sheet metal surfaces touch with the large circles of the truncated cones and the adjoining shaped sheets.
Fig. 5 zeigt den in Fig. 3 mit einem Kreis K umrandeten Bereich des erfindungsge mäßen Speicherbehälters. Fig. 5 shows the area in Fig. 3 outlined with a circle K of the storage container according to the invention.
Das Verbinden der gegensinnig gestapelten Formbleche 5 untereinander, mit den Sidebars 8 und mit den Deckblechen 3 bzw. 3′ sowie das Verbinden der Deckbleche 3 bzw. 3′ mit den Sidebars 8 kann z. B. mittels punktförmigem Verschweißen 9 erfolgen. Das Kommunizieren der durch die Formbleche 5 gebildeten Innenräume bzw. Kam mern wird durch die Bohrungen 6 ermöglicht.The connection of the oppositely stacked shaped plates 5 with each other, with the sidebars 8 and with the cover plates 3 and 3 'and the connection of the cover plates 3 and 3 ' with the sidebars 8 can, for. B. done by spot welding 9 . The communication of the interiors or chambers formed by the metal sheets 5 is made possible by the holes 6 .
Neben den in den Fig. 1 bis 5 gezeigten Formen der Formbleche können die Auswölbungen z. B. auch in Form von Zylindern, Pyramidenstümpfen, Prismen, etc., gebildet sein, d. h. von der Seite betrachtet, Rechteck- oder Trapezform - siehe Fig. 1 bzw. 2 und 3 -, bei geringem Betriebsdruck des Speicherraumes aber auch Sinus- oder Halbrundformen aufweisen. Denkbar sind auch Kombinationen aus den vorgenannten Formen.In addition to the shapes of the sheet metal shown in FIGS . 1 to 5, the bulges z. B. also in the form of cylinders, truncated pyramids, prisms, etc., formed, ie viewed from the side, rectangular or trapezoidal shape - see Fig. 1 or 2 and 3 -, with low operating pressure of the storage space but also sine or Have semicircular shapes. Combinations of the aforementioned forms are also conceivable.
Der Abschluß des Speicherraumes, gemäß der Erfindung, nach oben und unten erfolgt wiederum mittels Deckbleche 3 bzw. 3′. Im Falle niederer Drücke kann auf die Deck bleche 3 bzw. 3′ verzichtet werden, so daß der obere und untere Abschluß des Spei cheraumes durch die Formbleche selbst gebildet wird.The conclusion of the storage space, according to the invention, up and down again takes place by means of cover plates 3 and 3 '. In the case of low pressures, the cover plates 3 and 3 'can be dispensed with, so that the upper and lower ends of the storage space are formed by the shaped plates themselves.
Zur Seite hin wird der Speicherraum, gemäß der Erfindung mittels sog. Sidebars 8 abgeschlossen. Die Formbleche 5 können aufgrund ihrer Formgebung sowohl die vertikalen Druckkräfte von den Deckblechen 3 und 3′ als auch die horizontalen Druck kräfte von den Sidebars 8 aufnehmen.According to the invention, the storage space is closed to the side by means of so-called sidebars 8 . The mold plates 5 can absorb both the vertical pressure forces from the cover plates 3 and 3 'and the horizontal pressure forces from the sidebars 8 due to their shape.
Fig. 4 zeigt einen Schnitt durch den in Fig. 3 dargestellten Speicherraum. FIG. 4 shows a section through the memory space shown in FIG. 3.
Während bei herkömmlichen, zylindrischen Speicherbehälterkonstruktionen der Einbau von Schwall- bzw. Schwappblechen notwendig sein kann, kann bei einem Speicherbe hälter gemäß der vorliegenden Erfindung darauf verzichtet werden. Bei einem Speicherbehälter gemäß der Erfindung bewirkt die Formgebung der Bleche eine Auf teilung des Speichervolumens in eine Vielzahl einzelner Innenräume bzw. Kammern, so daß sich Schwall- bzw. Schwappbleche erübrigen.While with conventional, cylindrical storage tank designs the installation of baffles or slosh plates may be necessary in a storage tank Containers are dispensed with according to the present invention. At a Storage container according to the invention causes the shaping of the sheets division of the storage volume into a large number of individual interiors or chambers, so that baffles or slosh plates are unnecessary.
Aufgrund der Waben-artigen Konstruktion des Speicherraumes können die Formbleche aus relativ dünnwandigen Blechen hergestellt werden. Dies führt zum einen zu einem vergleichsweise niedrigen Gesamtgewicht des Speicherbehälters und ermöglicht zum anderen eine automatisierte Fertigung des Speicherbehälters. Due to the honeycomb-like construction of the storage space, the shaped sheets can be made from relatively thin-walled sheets. On the one hand, this leads to one comparatively low total weight of the storage container and allows for another automated production of the storage container.
Gemäß einer Ausgestaltung des erfindungsgemäßen Speicherbehälters weisen die Formbleche 5 und/oder die Zwischenbleche 4 querliegende, horizontale Schlitze auf. Diese Schlitze sind vorzugsweise gegeneinander seitlich versetzt, so daß sich für den Wärmefluß eine große Länge ergibt. Dies reduziert den Wärmefluß von den außenlie genden Flächen, insbesondere von oben, in das innerhalb des Speicherraumes befind liche kryogene Medium.According to an embodiment of the storage container according to the invention, the shaped plates 5 and / or the intermediate plates 4 have horizontal slits lying transversely. These slots are preferably laterally offset from one another, so that there is a great length for the heat flow. This reduces the heat flow from the outer surfaces, in particular from above, into the cryogenic medium located within the storage space.
Obwohl die Erfindung anhand eines Speicherbehälters für kryogene Medien, wie z. B. Wasserstoff oder LNG, und anhand der Verwendung eines derartigen Speicherbe hälters in einem Kfz, beschrieben wurde, ist es doch für einen Fachmann selbstver ständlich, daß der wesentliche Erfindungsgedanke prinzipiell bei der Speicherung von flüssigen oder gasförmigen Medien, insbesondere unter Druck, angewendet werden kann.Although the invention uses a storage container for cryogenic media, such as. B. Hydrogen or LNG, and by using such a storage container in a motor vehicle, it has been described for a person skilled in the art of course, that the main idea of the invention in principle when storing liquid or gaseous media, especially under pressure can.
Immer dann, wenn ein Speicherbehälter, der das Entstehen von unerwünschten Lückenvolumina vermeidet, benötigt wird, ist ein Speicherbehälter gemäß der vorlie genden Erfindung heranzuziehen. Da das Problem der unerwünschten Lückenvolumina insbesondere bei Kfz-Speicherbehältern auftritt, eignet sich der erfindungsgemäße Speicherbehälter insbesondere als Speicherbehälter für Flüssig-Wasserstoff oder LNG in land- und nichtlandgebundenen Verkehrsmitteln, wie z. B. Kfz′s, Schiffe, Flugzeuge, etc.Whenever there is a storage container, the emergence of unwanted Avoiding gap volumes is needed, is a storage container according to the present ing invention. Because the problem of unwanted gap volumes occurs in particular in motor vehicle storage containers, the invention is suitable Storage tanks in particular as storage tanks for liquid hydrogen or LNG in land and non-land transport, such as B. vehicles, ships, planes, Etc.
Es sei abschließend nochmals darauf hingewiesen, daß der erfindungsgemäße Speicherbehälter auch für die Speicherung von gasförmigen oder flüssigen Medien dienen kann, bei deren Speicherung weder ein Druckbehälter noch eine Isolierung notwendig ist.It should finally be pointed out again that the invention Storage containers also for storing gaseous or liquid media can serve when storing neither a pressure vessel nor insulation necessary is.
