Abstract
Description
Die
Erfindung betrifft einen Kryotank für ein Kraftfahrzeug, mit einer
Vakuum-Isolationsschicht zwischen
einem den kryogenen Kraftstoff aufnehmenden Innentank und einem
Außentank,
wobei in der Vakuum-Isolationsschicht zumindest eine weitere zwischen
dem Innentank und dem Außentank
liegende Hülle
vorgesehen ist, insbesondere mit einer Verwertungseinrichtung für durch
unvermeidbaren Wärmeeinfall
in den Innentank abgeblasenes boil-off-Gas. Zum technischen Umfeld
wird auf die
Für Kraftfahrzeuge werden zu Erdölderivaten alternative Kraftstoffe untersucht, so beispielsweise Wasserstoff, der dann im flüssigen bzw. kryogenen Zustand in einem geeigneten Tank gespeichert werden muss. Ein solcher Druckbehälter für Flüssigwasserstoff oder andere kondensierte Gase benötigt aufgrund der tiefen Speichertemperaturen eine effektive Isolation. Zur Vermeidung des Wärmeeintrags in den Tank wird wegen der geforderten Isolationsgüte üblicherweise ein doppelwandiger Behälter mit einer Vielschichtisolation im Hochvakuum verwendet. Dieser Vakuumraum befindet sich zwischen dem genannten Innentank und dem sog. Außentank, und in diesem Vakuumraum sind üblicherweise noch geeignete Isolationsfolien vorgesehen.For motor vehicles become oil derivatives examines alternative fuels, such as hydrogen, then in the liquid or cryogenic state are stored in a suitable tank got to. Such a pressure vessel for liquid hydrogen or other condensed gases requires due to the low storage temperatures effective isolation. To avoid the heat input into the tank is because of the required insulation quality usually a double-walled container used with a multilayer insulation in a high vacuum. This vacuum space is located between said inner tank and the so-called. External tank, and in this vacuum space are common still provided suitable insulation films.
Sollte eine Undichtigkeit am Innentank oder am Außentank oder an den im Vakuumraum verlaufenden Rohrleitungen, über die der Kraftstoff in den Innentank hinein bzw. aus diesem herausgeführt wird, auftreten, so wird dieser Vakuumraum mit dem jeweiligen Gas, nämlich im Falle einer Undichtigkeit des Außentanks mit Umgebungsluft bzw. im Falle einer Undichtigkeit des Innentanks mit dem darin gespeicherten Gas, geflutet. Aufgrund des hierdurch bedingten Ausfalls der Vakuum-Isolationsschicht steigt der Wärmeeintrag in den Innen-Tank schlagartig an, was zu einem hohen Druckanstieg im Innentank führt. Um ein Bersten dieses Innentanks zu verhindern, wird dieser Druck durch Abblasen des Gases in die Umgebung abgebaut. Befindet sich nun der Kryotank bzw. das damit versehene Kraftfahrzeug in einem geschlossenen Raum (bspw. Tiefgarage), so kann es in diesem Raum zu einer Anreicherung des Gases kommen, wodurch eine Explosionsgefahr entsteht.Should a leak on the inner tank or on the outer tank or in the vacuum space running pipes, over the fuel is led into or out of the inner tank, occur, so this vacuum space with the respective gas, namely in Leakage of the outer tank with ambient air or in case of leakage of the inner tank with the stored therein Gas, flooded. Due to the resulting failure of the vacuum insulation layer increases the heat input in the inner tank abruptly, resulting in a high pressure rise in the inner tank leads. To prevent bursting of this inner tank, this pressure Degraded by blowing off the gas into the environment. Is located now the cryotank or the motor vehicle provided with it in one closed room (eg underground parking), so it can in this room come to an enrichment of the gas, creating a risk of explosion arises.
Grundsätzlich sollen Kraftfahrzeuge mit Kryotanks zwar mit sog. Verwertungseinrichtungen für die sog. boil-off-Gase ausgerüstet werden, da nach derzeitigem Entwicklungsstand eine 100%ige Isolation des Kryotanks gegen Wärmeeinfall nicht möglich ist. Wird also ein Kraftfahrzeug mit einem zunächst vollständig befüllen Kryotank für längere Zeit nicht benutzt, so erhöht sich aufgrund des unvermeidbaren Wärmeeinfalls in den Tank der Druck im Innenbehälter, was nur bis zu einem gewissen Grenzwert toleriert werden kann. Bei weiterer Druckerhöhung muss eine Teilmenge des sich im Innentank bildenden Kraftstoff-Gases nach außen abgeblasen werden, und zwar als sog. boil-off-Gas. Um auch hier eine Gefährdung in einem geschlossenen Raum, insbesondere in einer Garage, zu verhindern, wird dieses boil-off-Gas zunächst in einer sog. Verwertungseinrichtung oxidiert, d.h. im wesentlichen vollständig in einen ungefährlichen Zustand chemisch umgewandelt. In dieser Verwertungseinrichtung kann bspw. eine katalytische Verbrennung oder eine Verbrennung mit Flamme erfolgen, es kann jedoch auch das Fahrzeug-Antriebsaggregat bspw. in Form einer Brennkraftma schine oder oder allgemein ein den Kraftstoff verwertender Energieerzeuger, bspw. eine Brennstoffzelle, als sog. Verwertungseinrichtung fungieren.Basically should Motor vehicles with cryogenic tanks, although with so-called. Utilization facilities for the So-called boil-off gases equipped because, according to the current state of development, a 100% isolation the cryotank against heat not possible. So is a motor vehicle with a first completely filled Kryotank for a long time not used, so increased due to the unavoidable heat in the tank of Pressure in the inner container, which can only be tolerated up to a certain limit. at further pressure increase must a subset of the forming in the inner tank fuel gas outward be blown off, as so-called boil-off gas. Here too one endangering in a closed room, especially in a garage, to prevent will this boil-off gas first oxidized in a so-called utilization device, i. essentially completely in a harmless one Condition chemically converted. In this recycling facility can, for example. catalytic combustion or combustion with flame, However, it can also be the vehicle-drive unit, for example. In the form a Brennkraftma machine or or generally a the fuel recycling energy generator, eg. A fuel cell, as so-called. Recycling facility act.
Neben
den eingangs geschilderten Kryotanks für Kraftfahrzeuge mit einer
Vakuum-Isolationsschicht zwischen dem Innentank und dem Außentank
sind noch Kryotanks mit einem zusätzlichen sog. Strahlungsschild
in der Vakuum-Isolationsschicht
bekannt, vgl. die eingangs genannte
Nunmehr zurückkommend auf einen bislang üblichen Kryotank für ein Kraftfahrzeug mit einer Vakuum-Isolationsschicht zwischen einem den kryogenen Kraftstoff aufnehmenden Innentank und einem Außentank soll hiermit nun eine Lösung für die weiter oben geschilderte Problematik im Falle einer Undichtigkeit des Außentanks oder Innentanks aufgezeigt werden (= Aufgabe der vorliegenden Erfindung).Now Returning on a hitherto usual Cryotank for a motor vehicle with a vacuum insulation layer between a the cryogenic fuel receiving inner tank and an outer tank This is a solution for the previously described problem in the event of a leak the outer tank or inner tanks are shown (= object of the present invention).
Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, dass eine grundsätzlich bereits bekannte, zwischen dem Außentank und dem Innentank in der Vakuum-Isolationsschicht liegende Hülle derart druckdicht gestaltet ist, dass sie im Falle einer Undichtigkeit des Innentanks oder Außentanks das Vakuum zwischen der Hülle und dem weiterhin dichten Tank soweit aufrecht erhalten und somit eine derartige Isolationswirkung entfalten kann, dass boil-off-Gas, welches aufgrund des durch die besagte Undichtigkeit gesteigerten Wärmeeinfalls in verstärktem Maße abgeblasen wird, in einer bzw. der dem Kryotank zugeordneten Verwertungseinrichtung für boil-off-Gas im wesentlichen vollständig ungefährlich gemacht, insbesondere oxidiert werden kann. Dabei unterscheidet sich eine erfindungsgemäße Hülle grundsätzlich von den bekannten im Vakuumraum angeordneten Isolationsfolien, da letztere nicht druckdicht sind, erstere hingegen zumindest für eine gewisse Zeitspanne schon. Gemäß einer vorteilhaften Weiterbildung steht dabei eine Leitung für das boil-off-Gas mit der Hülle in wärmeleitender Verbindung.The solution to this problem is characterized in that a basically already known, lying between the outer tank and the inner tank in the vacuum insulation layer envelope is designed so pressure-tight that in case of leakage of the inner tank or outer tank, the vacuum between the shell and the continue dense tank so far maintained and thus can develop such an insulating effect that boil-off gas, which is blown off due to the increased heat by the said heat leakage to a greater extent, in one or the cryotank associated recovery device for boil-off gas made completely harmless, in particular can be oxidized. In this case, a casing according to the invention fundamentally differs from the known insulating films arranged in the vacuum space, since the latter are not pressure-tight, the former, however, at least for one certain amount of time already. According to an advantageous development is a line for the boil-off gas with the shell in heat-conducting connection.
Erfindungsgemäß wird die
Vakuum-Isolationsschicht bzw. der Vakuumraum mit mindestens einer
zusätzlichen
Hülle oder
dgl. abgegrenzt bzw. in zumindest zwei ineinander angeordnete Vakuumräume unterteit.
Es wird somit zumindest ein innerer Vakuumraum sowie ein äußerer, den
inneren Raum umgebender Vakuumraum gebildet, zwischen denen sich
druckdicht die sog. Hülle
befindet. Diese Hülle soll
in der Lage sein, auf ihrer einen Seite ein dort vorhandenes Vakuum
aufrechtzuerhalten, wenn das Vakuum auf ihrer anderen Seite zerstört wurde.

zeichnet sich im Falle eines Undichtigkeit des Außentanks oder
Innentanks vorteilhafterweise durch eine verlängerte Standzeit aufgrund eines
geringeren Wärmeeintrags
aus , d.h. die Druckaufbauzeit bis zum Abblasen von boil-off-Gas
ist verlängert
und bietet zusätzliche
Sicherheit insbesondere auch bei einem Unfall des hiermit ausgestatteten
Kraftfahrzeugs. Insgesamt ergibt sich somit ein kalkulierbares Risiko
im Falle des Versagens eines Vakuumraumes, wobei insbesondere das
Kraftfahrzeug auch problemlos in Tiefgaragen abgestellt und in längeren Tunnels
betrieben werden kann, wobei noch darauf hingewiesen sei, dass durchaus
eine Vielzahl von Details abweichend von obigen Erläuterungen
gestaltet sein kann, ohne den Inhalt der Patentansprüche zu verlassen. So

beispielsweise auch mehrere sog. druckdichte Hüllen einander einhüllend im
