Description

Die Erfindung betrifft eine Vorrichtung zum Umwandeln des Boil-Off-Gases eines Kryo-Kraftstofftanks mit einer Verbrennungseinrichtung für das Boil-Off-Gas sowie mit einem thermoelektrischen Generator zur Gewinnung elektrischer Energie aus der bei diesem Umwandlungsprozess freiwerdenden Wärme, und geht aus von der DE 198 54 581 A1 .The invention relates to a device for converting the boil-off gas of a cryogenic fuel tank with a boil-off gas combustion device as well as with a thermoelectric generator for recovering electrical energy from the released in this conversion process heat, and starts from the DE 198 54 581 A1 ,

In der genannten Schrift ist nicht nur die sog. Boil-Off-Problematik in Verbindung mit Kryo-Kraftstofftanks, die dem Fachmann grundsätzlich bekannt ist und daher an dieser Stelle nicht weiter erläutert wird, beschrieben, sondern es ist hierin auch vorgeschlagen, die Abwärme, die bei der notwendigen Verbrennung des unerwünschterweise aus einem Kryo-Tank abzublasenden Boil-off-Gases frei wird, zu nutzen, indem ein dort sog. Energiewandler in Form eines Thermoelements mit dieser Abwärme beaufschlagt wird und somit elektrischen Strom erzeugen kann. Bei diesem Thermoelement handelt es sich somit um einen thermoelektrischen Generator, wobei entsprechende Elemente auch als Seebeck-Elemente bekannt sind. Diese sind üblicherweise aus zwei unterschiedlichen elektrischen Halbleiter-Materialien aufgebaut, die thermisch und elektrisch leitend miteinander verbunden sind. Setzt man diese Materialpaarung einem Temperaturgefälle zwischen einer Wärmequelle und einer Wärmesenke aus, bildet sich in dieser Materialpaarung eine elektrische Spannung. Durch Kombination einer Vielzahl von solchen Materialpaarungen können bei entsprechend leistungsfähiger Wärmequelle und Wärmesenke wirtschaftlich nutzbare elektrische Leistungen erzielt werden.In The mentioned document is not only the so-called. Boil-off problem in connection with cryogenic fuel tanks, which is basically known to the person skilled in the art and therefore will not be explained further at this point, but described It is also suggested here that the waste heat that is necessary Burning the unwanted released from a cryogenic tank boil-off gas is released to use by a so-called energy converter in the form of a thermocouple with this waste heat is applied and thus can generate electricity. at This thermocouple is thus a thermoelectric Generator, whereby appropriate elements also as Seebeck elements are known. These are usually constructed from two different electrical semiconductor materials, which are thermally and electrically connected to each other. If one sets this material pairing between a temperature gradient a heat source and a heat sink out, forms an electrical voltage in this pair of materials. By combining a variety of such material pairings can at correspondingly more efficient heat source and heat sink economically usable electrical power can be achieved.

Eine Maßnahme zur Steigerung des Wirkungsgrads bzw. der erzeugbaren elektrischen Leistung einer Vorrichtung nach dem Anspruch 1 aufzuzeigen, ist Aufgabe der vorliegenden Erfindung.A measure to increase the efficiency or the producible electrical Performance of a device according to claim 1 show is Object of the present invention.

Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, dass, während die sog. warme Seite des thermoelektrischen Generators mit der bei der insbesondere katalytischen Verbrennung des Boil-Off-Gases freiwerdenden Wärme beaufschlagt wird, die andere sog. kalte Seite des thermoelektrischen Generators mit dem kalten aus dem Kraftstofftank abgeführten Boil-Off-Gas beaufschlagt wird.The solution this object is characterized in that while the so-called. Warm side of the thermoelectric generator with the in particular catalytic combustion of boil-off gas released heat is applied, the other so-called. Cold side of the thermoelectric generator with the cold discharged from the fuel tank boil-off gas is applied.

Mit dieser vorgeschlagenen Maßnahme ist am thermoelektrischen Generator eine wesentlich größere Temperaturdifferenz zwischen der Wärmequelle, nämlich dem verbrannten Boil-Off-Gas, und der Wärmesenke, nämlich dem frisch aus dem Kryo-Tank abgeführten Boil-Off-Gas, darstellbar, als wenn – wie im bekannten Stand der Technik – als Wärmesenke (höchstwahrscheinlich) die Umgebungsluft herangezogen wird. Mit der erfindungsgemäß erheblich größeren Temperaturdifferenz, die durchaus in der Größenordnung von mehreren 100 Grad liegen kann, nachdem die Temperatur des kalten, unverbrannten Boil-Off-Gases in der Größenordnung von wenigen Kelvin liegt, wird die im thermoelektrischen Generator erzeugbare elektrische Energie naturgemäß erheblich gesteigert.With this proposed action is at the thermoelectric generator a much larger temperature difference between the heat source, namely the burnt boil-off gas, and the heat sink, fresh from the cryo tank dissipated Boil-off gas, representable, as if - as in the known state of Technology - as a heat sink (Most likely) the ambient air is used. With the invention considerably greater temperature difference, which are quite on the order of magnitude can be several hundred degrees after the temperature of the cold, unburned boil-off gas on the order of a few Kelvin is the producible in the thermoelectric generator electric Energy, of course, considerably increased.

Eine konstruktiv besonders vorteilhafte, da unter Bauraumaspekten sowie im Hinblick auf eine bestmögliche Wärmeübertragung zwischen den jeweiligen Elementen günstige konstruktive Anordnung ergibt sich, wenn eine Batterie (Vielzahl) von thermoelektrischen Generatoren das Gehäuse einer katalytischen Verbrennungseinrichtung umhüllend angeordnet sind und diese thermoelektrischen Generatoren mit ihrer dem Gehäuse der katalytischen Verbrennungsweinrichtung abgewandten Seite mit einem das kalte Boil-Off-Gas führenden und die Verbrennungseinrichtung mit den thermoelektrischen Generatoren umhüllenden Ringkanal in wärmeübertragender Verbindung stehen. Anstelle einer solchen Gestaltung ist jedoch auch eine Matrixstruktur des thermoelektrischen Generators möglich, die so gestaltet ist, dass sie mit einer Seite das Gehäuse einer katalytischen Verbrennungseinrichtung für das Boil-Off-Gas kontaktiert und mit der anderen Seite einen geeignet geformten Kanal oder dgl., durch den der genannten katalytischen Verbrennungseinrichtung das Boil-Off-Gas zur Oxidation zugeführt wird.A structurally particularly advantageous because under construction space aspects as well with a view to the best possible heat transfer results in favorable structural arrangement between the respective elements itself when a battery (multitude) of thermoelectric generators the housing a catalytic combustion device are arranged enveloping and this thermoelectric generators with their housing the catalytic combustion device opposite side with a cold boil-off gas leading and the combustion device with the thermoelectric generators enveloping annular channel in heat transfer Connection stand. However, instead of such a design is Also, a matrix structure of the thermoelectric generator possible, the is designed so that with one side the case of a catalytic Incinerator for the boil-off gas contacted and with the other side a suitable shaped channel or the like. Through which said catalytic Combustion means the boil-off gas is fed to the oxidation.

Die am thermoelektrischen Generator anfallende bzw. freiwerdende elektrische Energie kann vorzugsweise einem Sicherheitssystem zur Überwachung und Steuerung des sog. Boil-Off-Prozesses zur Verfügung gestellt werden. Insbesondere bei mit Kryo-Kraftstofftanks ausgestatteten Kraftfahrzeugen stellt die kontinuierliche Energieversorgung eines Boil-Off-Managementsystems nämlich ein Problem dar. Unter Umständen über einen relativ langen Zeitraum hinweg kann es nämlich erforderlich sein, eine geeignete Sensorik, Ventile sowie eine elektronische Überwachungseinheit zur Prozess-Steuerung, im Rahmen derer Boil-Off-Gas aus dem Kryotank abgeblasen und einer bzw. der Verbrennungseinrichtung zugeführt wird, sowie ggf. auch eine Zündeinrichtung der besagten Verbrennungseinrichtung, mit elektrischer Energie zu versorgen. Wenn die hierfür benötigte Energie nun quasi durch die notwendige Verbrennung des Boil-Off-Gases erzeugt und in einem geeignetne Pufferspeicher zwischengespeichert wird, so kann hiermit das genannte Energieversorgungsproblem auf elegante Weise und vorteilhafterweise wirkungsgradgünstig gelöst werden.The at the thermoelectric generator accumulating or released electrical Energy may preferably be a security system for monitoring and control of the so-called boil-off process provided become. Especially with equipped with cryo fuel tanks Motor vehicles provides the continuous power supply of a boil-off management system namely a problem In fact, a relatively long period of time may require a suitable Sensors, valves and an electronic monitoring unit for process control, in the context of which boil-off gas blown out of the cryogenic tank and a or the combustion device is supplied, and possibly also a Ignition device of said combustion device to provide electrical energy. If that for this needed Energy now quasi by the necessary combustion of Boil-off gas generated and cached in a suitable buffer memory, Thus, the aforementioned energy supply problem can be elegant Way and advantageously achieved low-efficiency.
