Abstract

A storage vessel (3) and filling station (2) are separate modules and individually portable. The filling station, with an evaporator, pump and cylinder-filling connections, can be set down from a vehicle. Cylinder connections, when operational, allow space for cylinders (6) or cylinder palettes. They can be raised or swung up. The storage vessel can be connected to the filling station with a dead space-free coupling and line. A second separate line which can be shut off, joins filling station and the head space of the storage vessel. Preferred Features: The filling station has a lifting system and a hinged sidewall. Its support for cylinder connectors can be lowered to cylinders on palettes. It is located on the underside of, or on a side wall of the filling station. The filling plant has valves for gas venting from storage. Meters in the filling line measure the weight of gas, gas pressure and temperatures. The lines connected to the storage vessel are connected to a high pressure pump; gas evaporated in the pump is recycled.

Description

Die Erfindung bezieht sich auf eine mobile Füllanlage für Druckgasflaschen, mit einem Speicher für kryogen verflüssigte Gase, wenigstens einer Pumpe und einer Füllstation zum Anschluß an zu befüllende Druckgasflaschen.The invention relates to a mobile filling system for compressed gas cylinders, with a storage for cryogenically liquefied gases, at least one pump and a filling station for connection to filling compressed gas cylinders.

In der DE 32 01 660 A1 ist eine mobile Flüssiggasversorgung beschrieben, bei welcher ein Transport- und Lagerbehälter zur Versorgung von Propangasgroßverbrauchern mit wechselndem Standort vorgesehen ist. Der Flüssiggastank ist hiebei auf einem Fahrzeug gemeinsam mit einer Verdampferanlage angeordnet, sodaß ein mobiler Tankwagen für den Anschluß an stationäre Verbraucher geschaffen wird. Eine Befüllung von Flaschen an unterschiedlichen Standorten ist mit einer derartigen Einrichtung nicht möglich. Es werden aufwendige sicherheitstechnische Vorkehrungen für einen Flüssiggastank und eine Verdampferanlage auf einem gemeinsamen Fahrzeug, aus welcher in der Folge kontinuierlich Propangas entnommen werden kann, beschrieben. Prinzipiell ersetzt eine derartige Flüssiggasversorgungseinrichtung die entsprechend kleineren Druckgasflaschen, wobei unmittelbar für einen kurzfristigen hohen Verbrauch, wie beispielsweise für Zeltbetriebe, Waffelbäckereien und Grillbetrieben, die entsprechende Gasmenge kontinuierlich zur Verfügung gestellt werden kann.DE 32 01 660 A1 describes a mobile liquid gas supply, in which a transport and storage container for supply of bulk propane gas consumers with changing locations is provided. The liquid gas tank is on a vehicle arranged together with an evaporator system, so that a mobile Tank trucks for connection to stationary consumers is created. A filling of bottles at different Locations is not with such a facility possible. There will be elaborate safety precautions for a liquid gas tank and an evaporator system on one common vehicle, from which in the consequence continuously Propane gas can be removed, described. In principle replaced such a liquid gas supply device accordingly smaller compressed gas cylinders, being immediately for short-term high consumption, such as for Tent companies, wafer bakeries and grill companies, the corresponding Amount of gas can be made available continuously can.

Aus der US-A 5 762 119 ist eine mobile Füllanlage für Gasflaschen bekannt, bei welcher kryogen verflüssigte Gase auf einem Sattelschlepper gemeinsam mit einem Verdampfer und einer Druckpumpe bereitgestellt werden, sodaß unmittelbar verbraucherseitige Behälter mit Druckgas gefüllt werden können. Das kryogen verflüssigte Gas wird zu diesem Zweck verdampft und über den Kompressor bzw. die Pumpe in den jeweiligen Gastank abgefüllt. Bei dieser Bauweise ist auf einem gemeinsamen Rahmen der Tank, die Pumpe und der Verdampfer angeordnet, sodaß naturgemäß gleichfalls ein hohes Maß an Sicherheitsvorkehrungen erforderlich ist, wobei zur Bereitstellung weiterer Gase die gesamte Anlage gemeinsam mit dem Verdampfer und der Pumpe wiederum an den Ort der Befüllung mit kryogen verflüssigten Gasen verfahren werden muß.From US-A 5 762 119 is a mobile filling system for gas bottles known at which cryogenically liquefied gases a semi-trailer together with an evaporator and one Pressure pump are provided so that immediately consumer-side Containers can be filled with compressed gas. That cryogenic liquefied gas is evaporated for this purpose and over the Compressor or the pump filled in the respective gas tank. With this construction, the tank is on a common frame, the pump and the evaporator arranged, so naturally a high level of security is also required is, with the entire to provide additional gases System together with the evaporator and the pump move the place of filling with cryogenically liquefied gases must become.

Eine ähnliche Ausbildung ist auch der DE 196 53 731 A1 zu entnehmen, welche eine auf einem Kraftfahrzeug angeordnete Zapfanlage zur Befüllung von mobilen Gastanks beschreibt. Bei dieser bekannten Einrichtung wird allerdings Druckgas aus Flaschen über einen Verdichter an die Zapfsäule auf einem transportablen Traggestell gefördert, wobei eine große Anzahl von relativ schweren Druckgasflaschen transportiert werden muß und daher ein häufiger Austausch der Druckgasflaschen erforderlich ist. Eine Verdampfung von Flüssiggasen ist bei einer derartigen Einrichtung nicht vorgesehen.A similar design can also be found in DE 196 53 731 A1, which is a dispensing system arranged on a motor vehicle describes how to fill mobile gas tanks. At this known device, however, is compressed gas from bottles a compressor to the petrol pump on a portable support frame promoted, with a large number of relatively serious Pressurized gas cylinders must be transported and therefore a more common one Replacement of the compressed gas cylinders is required. An evaporation of liquid gases is in such a device not provided.

Die Erfindung zielt nun darauf ab, eine mobile Füllanlage für Gasflaschen zu schaffen, mit welchen an Stellen, an welchen ein großer Bedarf an Gasflaschen bzw. Druckgasbehältern besteht, unmittelbar technische Gase, wie beispielsweise Argon, Sauerstoff und Stickstoff, einzeln oder Gemische davon vor Ort abgefüllt werden können, sodaß der aufwendige Transport von schweren Druckgasflaschen über lange Strecken entfallen kann und eine große Menge von Druckgasflaschen vor Ort ohne aufwendige Transportwege befüllt werden kann. Die erfindungsgemäße Füllanlage soll hiebei vor allen Dingen auch alle sicherheitstechnischen Erfordernisse erfüllen und die Transportwege und die Transportgewichte entsprechend minimieren. Zur Lösung dieser Aufgabe besteht die mobile Füllanlage der eingangs genannten Art im wesentlichen darin, daß der Speicher und die Füllstation als gesonderte Baueinheiten ausgebildet sind und gesondert verfahrbar sind, daß die Füllstation wenigstens eine Pumpe, einen Verdampfer und die Anschlüsse für die Flaschen aufweist und von einem Fahrzeug absetzbar ausgebildet ist, wobei die Anschlüsse für die Druckgasflaschen der Füllstation in eine Betriebslage unter Schaffung eines Freiraumes für Flaschen oder Flaschenpaletten anhebbar oder schwenkbar sind, und daß der von der Füllstation gesonderte Speicher über eine totraumfreie Kupplung und eine erste Leitung mit der Füllstation verbindbar ist, und daß eine zweite absperrbare Leitung zwischen Füllstation und Speicher in den Gasraum des Speichers mündet. Dadurch, daß Speicher und Füllstation als gesonderte Baueinheiten ausgebildet sind und gesondert verfahrbar sind, kann an denjenigen Stellen, an welchen ein hoher Bedarf an Druckgasflaschen besteht, kurzfristig eine Füllstation errichtet werden, wobei das für die Abfüllung erforderliche Gas in flüssiger Form gesondert bereitgestellt werden kann. Durch die gesonderte Bereitstellung der Speicher und der Füllstation, welche jeweils gesondert verfahrbar sind, gelingt es die Füllstation kurzfristig und mit geringstem Aufwand auf unterschiedliche technische Gase umzustellen und den jeweiligen Bedürfnissen des Verbrauchers anzupassen, wobei Transportwege lediglich für die entsprechenden Speicher für kryogen verflüssigte Gase, welche gesondert verfahrbar sind, entstehen. Im Speicher für kryogen verflüssigte Gase können die Gase unmittelbar von der Produktionsstätte, beispielsweise der Luftzerlegungsanlage, zum Füllwerk in tiefkalt verflüssigter Form transportiert werden, wobei eine Umfüllung in Lagertanks, wie dies bei konventionellen stationären Anlagen erforderlich wäre, entfallen kann, da unmittelbar der mobile Speicher für den Betrieb der Füllstation Verwendung findet. Es entfällt somit der gesonderte Umfüllvorgang der üblicherweise mit einem Tankfahrzeug bereitgestellten flüssigen Gase in Lagertanks einer stationären Anlage und es wird unmittelbar ein Speicher, welcher gesondert verfahrbar ist, für die flexible Anpassung an die Bedürfnisse jeweils zu einer mobilen Füllanlage verbracht. Ebenso wie bei stationären Anlagen wird bei der Befüllung der Aggregatszustand gewechselt, wobei im Rahmen der mobilen Anlage gesonderte Fülllinien für jedes der einzelnen Hauptgase, wie beispielsweise Argon, Sauerstoff und Stickstoff, entbehrlich sind, da der Wechsel von einem Gas auf ein anderes oder die Mischung von Gasen unmittelbar durch Austausch der Speicher unter vorheriger Spülung der mobilen Füllanlage erfolgen kann. Gemäß der Erfindung wird somit die Füllanlage in funktionell gesonderte Einheiten, nämlich den Speicher und die Füllstation oder einzelne Teile der Füllstation, unterteilt, wodurch sicherheitstechnische Auflagen einfach und sicher erfüllt werden und aufgrund des modularen Aufbaues beispielsweise verschiedene Pumpen und/oder Verdampfer mit unterschiedlicher Leistung zum Einsatz gelangen können. Die mobile Füllstation ist hiebei gemäß der Erfindung mit wenigstens einer Pumpe, einem Verdampfer und Anschlüssen für die zu befüllenden Flaschen ausgestattet und von einem Fahrzeug absetzbar, wobei es von Vorteil ist, daß diese mobile Füllstation mit einer Hubeinrichtung ausgebildet ist, mit welcher die Füllstation von einer Transportposition in eine Betriebslage unter Schaffung eines Freiraumes für Flaschen oder Flaschenpaletten anhebbar ist. Auf diese Weise wird es auch mit der mobilen Füllanlage ebenso wie mit üblichen stationären Anlagen möglich, gleichzeitig eine große Zahl von Flaschen zu füllen und diese beispielsweise mit Flaschenpaletten jeweils unter die Füllstation zu verbringen, sodaß mit einem einfachen Absenken der entsprechenden Füllanschlüsse eine Mehrzahl von Flaschen befüllt werden kann. Dadurch, daß der von der Füllstation gesonderte Speicher über eine totraumfreie Kupplung und eine erste Leitung mit der Füllstation verbindbar ist, gelingt es den Spülaufwand für den Wechsel von einem technischen Gas auf ein anderes technisches Gas wesentlich zu verringern und insbesondere Verunreinigungen der Speicher und der Füllanlage bei einer Abkupplung und einem Neuanschluß eines anderen Speichers zu verringern. Dadurch, daß nun eine zweite Leitung zwischen Füllstation und Speicher in den Gasraum des Speichers mündet, wird die Möglichkeit geschaffen den Abfüllvorgang entsprechend zu steuern und beispielsweise die Anlage zuerst zu spülen oder beispielsweise in einem ersten Füllschritt lediglich Gas aus dem Gasraum des Speichers einzufüllen und erst in einem zweiten Füllschritt nach der Verdampfung des flüssigen Gases über die Hochdruckpumpe die endgültige Befüllung der Flaschen auf den vorgesehenen Betriebsdruck vorzunehmen.The invention now aims to provide a mobile filling system for To create gas bottles, with which in places, at which one there is a great need for gas cylinders or pressurized gas containers, directly industrial gases, such as argon, oxygen and nitrogen, individually or mixtures thereof, bottled on site can be, so that the complex transport of heavy Compressed gas cylinders can be omitted over long distances and one large amount of compressed gas cylinders on site without complex transport routes can be filled. The filling system according to the invention above all, all safety-related Meet requirements and the transport routes and transport weights minimize accordingly. To solve this task is the mobile filling system of the type mentioned in essential in that the memory and the filling station as separate units are formed and can be moved separately are that the filling station has at least one pump, one evaporator and has the connections for the bottles and from is designed to be removable from a vehicle, the connections for the compressed gas cylinders of the filling station in an operating position creating a free space for bottles or bottle pallets can be raised or pivoted, and that of the Filling station separate storage via a dead space-free coupling and a first line can be connected to the filling station, and that a second lockable line between the filling station and Storage opens into the gas space of the storage. As a result of that Storage and filling station designed as separate units are and can be moved separately, at those points where there is a high demand for compressed gas cylinders, in the short term a filling station to be built, which for the Filling required gas in liquid form provided separately can be. Through the separate provision of Storage and the filling station, each of which can be moved separately the filling station succeeds in the short term and with the least Switch effort to different technical gases and adapt to the respective needs of the consumer, where transport routes only for the corresponding storage for cryogenically liquefied gases, which can be moved separately, arise. In the storage for cryogenically liquefied gases Gases directly from the production site, for example the Air separation plant, to the filling plant in cryogenic liquefied Form are transported, a transfer into storage tanks, as is required with conventional stationary systems would be eliminated, since the mobile memory for the Operation of the filling station is used. The separate refilling process usually with a tanker provided liquid gases in storage tanks of a stationary Plant and it immediately becomes a store which is separately movable, for flexible adaptation to the Needs each spent on a mobile filling system. As well As with stationary systems, the state of aggregate becomes when filling changed, as part of the mobile system separate filling lines for each of the individual main gases, such as for example argon, oxygen and nitrogen, can be dispensed with because there is a change from one gas to another or that Mixing of gases immediately by exchanging the storage can be done with previous rinsing of the mobile filling system. According to the invention, the filling system is thus functional separate units, namely the memory and the filling station or individual parts of the filling station, divided, making safety Requirements are fulfilled easily and safely due to the modular structure, for example, different pumps and / or evaporators with different outputs can reach. The mobile filling station is accordingly the invention with at least one pump, an evaporator and Connections for the bottles to be filled and from a vehicle deductible, it is advantageous that this Mobile filling station is designed with a lifting device which moves the filling station from a transport position to a Operating situation creating a free space for bottles or Bottle pallets can be lifted. This way it will work with the mobile filling system as well as with conventional stationary systems possible to have a large number of bottles at the same time fill and fill them with bottle pallets, for example to spend under the filling station, so with a simple Lowering the corresponding filling connections a plurality of Bottles can be filled. Because of the filling station separate storage via a dead space-free coupling and a first line can be connected to the filling station it the flushing effort for the change from a technical gas to significantly reduce another technical gas and in particular Contamination of the storage and filling system a disconnection and a new connection of another memory to reduce. The fact that now a second line between Filling station and storage opens into the gas space of the storage, the possibility is created according to the filling process to control and, for example, to rinse the system first for example, in a first filling step, only gas from the Fill the gas space of the accumulator and only in a second one Filling step after the evaporation of the liquid gas over the High pressure pump the final filling of the bottles on the the intended operating pressure.

In besonders einfacher Weise ist die Füllstation mit wenigstens einer abklappbaren Seitenwand ausgebildet, sodaß sich nach dem Absetzen und Anheben der Füllstation eine portalartige Konstruktion ergibt, unter welche die Flaschen oder Flaschenpaletten verfahren werden können, sodaß ein rascher Füllvorgang auch mit einer derartigen mobilen Füllanlage gewährleistet ist. Wesentlich ist hiebei vor allen Dingen, daß die Möglichkeit geschaffen wird, gleichzeitig eine Mehrzahl von Flaschen ordnungsgemäß zu füllen, wobei die Ausbildung mit Vorteil so getroffen ist, daß die Füllstation einen Träger für Anschlüsse für eine Mehrzahl von Flaschen aufweist, welcher in Höhenrichtung auf eine Mehrzahl von in Paletten gehaltenen Flaschen absenkbar ist. Aufgrund der Trennung der Anlage in einen gesondert verfahrbaren mobilen Speicher und eine entsprechend mobile, aber nach dem Absetzen und Anheben in die Betriebslage mit hoher Wirtschaftlichkeit betreibbare Füllstation kann das jeweils gewünschte Produkt durch Verbinden mit dem entsprechenden Tankmodul bzw. Speicher in kürzester Zeit umgestellt werden, wobei im Gegensatz zu stationären Füllanlagen eine definierte Reinigungsprozedur beim Wechsel der Tankmodule bzw. Speicher für alle Gase genutzt werden kann. Der mobile Speicher, welcher die Funktion des stationären Lagertanks einer stationären Füllanlage übernimmt, kann hiebei gleichfalls vom Fahrzeug abgesetzt werden, wobei der wesentliche Vorteil gegenüber stationären Anlagen darin zu erblicken ist, daß eine weitere Zwischenlagerung in einem stationären Speicher für kryogen verflüssigte Gase entbehrlich ist. Während des Füllprozesses wird die Füllstation portalartig über den Flaschen positioniert, wobei durch die ausklappbaren Seitenwände des Füllmoduls bzw. der Füllstation eine großflächige Überdachung geschaffen wird, die in einfacher Weise beispielsweise durch seitliche markisenartige Vorhänge eine geschlossene wettergeschützte Arbeitsfläche ergibt. Prinzipiell kann die Anordnung hiebei so getroffen sein, daß der Träger für die Anschlüsse an der Unterseite oder einer Seitenwand der Füllstation gelagert ist, wobei beispielsweise durch Ausklappen einer Seitenwand in eine im wesentlichen horizontale Stellung ebenso wie bei der Anordnung der Anschlüsse an der Unterseite der Füllanlage der Vorteil erreicht wird, daß eine Mehrzahl von Flaschen und insbesondere auch eine Mehrzahl von in Paletten bereitgestellten Flaschen gleichzeitig unterhalb den jeweiligen Träger für die Anschlüsse verfahren werden kann und somit gleichzeitig befüllt werden kann. The filling station is at least in a particularly simple manner formed a hinged side wall, so that after Setting down and lifting the filling station a portal-like construction results under which the bottles or bottle pallets can be moved so that a rapid filling process with such a mobile filling system is guaranteed. Essential is above all that the possibility is created will, at the same time, properly fill a plurality of bottles fill, the training is advantageously made such that the filling station a carrier for connections for a plurality of bottles, which in the vertical direction to a plurality can be lowered from bottles held in pallets. by virtue of the separation of the system into a separately movable mobile Memory and a correspondingly mobile, but after weaning and lifting into the operating situation with high efficiency Operable filling station can be the desired product by connecting to the corresponding tank module or storage can be changed over in the shortest possible time, in contrast to stationary filling systems a defined cleaning procedure for Change of tank modules or storage used for all gases can be. The mobile memory, which is the function of the stationary storage tanks of a stationary filling system, can also be removed from the vehicle, the substantial advantage over stationary plants in it too behold is that another intermediate storage in one stationary storage for cryogenically liquefied gases can be dispensed with is. The filling station becomes portal-like during the filling process positioned above the bottles, with the fold-out Sidewalls of the filling module or the filling station a large area Canopy is created in a simple manner for example, through awnings on the side closed weather-protected work surface results. in principle the arrangement can be made so that the carrier for the connections on the underside or a side wall of the filling station is stored, for example by unfolding a side wall in a substantially horizontal position just as with the arrangement of the connections on the bottom the filling system has the advantage that a plurality of Bottles and especially a plurality of pallets provided bottles at the same time below the respective Carrier for the connections can be moved and thus can be filled at the same time.

Die Reinigung der Leitungen kann durch ein entsprechendes Spülsystem und insbesondere durch Druckwechsel mit dem nachfolgend zu füllenden Gas durch Einpressen oder Absaugen erfolgen. Der zu erwartende Druckanstieg im Speicher kann durch pumpenlose Gasentnahme, d.h. somit ein Überströmen von Gas in die Anlage oder leere Flaschen minimiert werden, sodaß das Gas gasseitig zu Beginn des Füllprozesses und für Spülungen der Anlage oder der Flaschen vor einer Befüllung unmittelbar hinter einem Gasabscheider entnommen und über ein Absperrventil mit dem Hochdruckteil verbunden sein kann. Mit Vorteil ist die erfindungsgemäße Füllanlage daher so ausgebildet, daß die Füllanlage mit Ventilen für die pumpenlose Gasentnahme aus dem Gasraum des Speichers ausgestattet ist.The lines can be cleaned using an appropriate flushing system and especially by changing pressure with the following gas to be filled by pressing or suction. The too expected pressure increase in the storage can be achieved by pumpless gas extraction, i.e. thus an overflow of gas into the system or empty bottles are minimized, so that the gas side too Start of the filling process and for rinsing the system or the Bottles before filling directly behind a gas separator removed and via a shut-off valve with the high pressure part can be connected. The one according to the invention is advantageous Filling system therefore designed so that the filling system with valves for pumpless gas extraction from the gas space of the storage Is provided.

Für die exakte Einstellung des gewünschten Mischungsverhältnisses von mehreren Gasen und für die exakte Einhaltung der vorgegebenen Werte für Druck und Gewicht der Druckgasflaschen ist die Ausbildung mit Vorteil so getroffen, daß die Füllanlage Meßeinrichtungen für das Gewicht der zu befüllenden Flaschen, den Gasdruck und die Gastemperatur in der Füllleitung aufweist. Die jeweils erforderliche Analyse der Gase kann hiebei direkt im Füllstand gezogen werden, wobei dadurch, daß die Füllanlage die entsprechenden Meßeinrichtungen aufweist, ein hohes Maß an Flexibilität in bezug auf den jeweils geforderten Füllalgorithmus erlaubt. In aller Regel erfolgt die Befüllung von Gasflaschen gravimetrisch, d.h. durch Bestimmung des Gewichtes. Bei Abfüllung einer Mischung mehrerer Gase können die einzelnen Gase abwechselnd in mehreren Schritten in die Flasche gefüllt werden, wodurch eine Vermischung provoziert wird und der Dichteunterschied des Gemisches zum Hauptgas oder Matrixgas verringert wird. Wenn somit im ersten Füllabschnitt ein Gemisch hergestellt wird, dessen Beimischung zum gewünschten Endprodukt prozentual zu hoch wäre, wird dieses Gemisch im zweiten Füllabschnitt mit dem Matrix- oder Hauptgas bis zur geforderten Konzentration verdünnt. For the exact setting of the desired mixing ratio of several gases and for the exact adherence to the given Values for pressure and weight of the compressed gas cylinders is the training taken with advantage so that the filling system measuring devices for the weight of the bottles to be filled Has gas pressure and the gas temperature in the filling line. The The required analysis of the gases can be done directly in the Level are drawn, the fact that the filling system corresponding measuring devices, a high degree of Flexibility with regard to the filling algorithm required in each case allowed. As a rule, gas bottles are filled gravimetric, i.e. by determining the weight. at Filling a mixture of several gases can be the individual gases alternately filled into the bottle in several steps, which provokes mixing and the difference in density of the mixture to the main gas or matrix gas is reduced becomes. If a mixture is thus produced in the first filling section whose admixture to the desired end product is a percentage would be too high, this mixture is in the second filling section diluted the matrix or main gas to the required concentration.

Die Füllstation kann konstruktiv nach Art eines Containers aufgebaut sein oder aber auf dem Prinzip einer Wechselpritsche basieren, wobei alle verteilenden Rohrleitungen und eventuell auch Armaturen sich am Boden des Containers der Füllstation befinden können. Zubehör für die Abfüllung, wie analytische Geräte, Datenübertragungseinrichtungen oder dgl., können entsprechend wettergeschützt untergebracht werden, wobei der Verdampferabschnitt in der Arbeitsposition von allen Seiten frei zugänglich sein kann, wobei lediglich eine Auffangfläche für abtropfendes Wasser oder Eis vorgesehen sein muß.The filling station can be constructed in the manner of a container be or on the principle of an interchangeable platform based, with all distributing pipes and possibly also fittings are on the bottom of the container of the filling station can be located. Filling accessories, such as analytical Devices, data transmission devices or the like., Can accordingly weatherproof housing, the evaporator section free from all sides in the working position can be accessible, with only one collecting area for dripping water or ice must be provided.

Die Füllstation kann vom Fahrzeug ohne Fremdhilfe abgesetzt werden und durch die entsprechende Hubeinrichtung beispielsweise eine Zahnstangenmechanik oder Hydraulikzylinderkolbenaggregate auf die gewünschte Arbeitsposition beispielsweise auf eine Höhe von etwa 2,5 m angehoben werden. Nach dem Abklappen einer oder zweier Seitenwände in eine waagrechte Position wird ein nach unten offener Raum unter dem Container geschaffen, welcher auch im Rahmen einer mobilen Füllanlage den entsprechenden Wetterschutz und die Betriebssicherheit über einen langen Zeitraum gewährleistet.The filling station can be removed from the vehicle without outside help be and by the appropriate lifting device, for example a rack and pinion mechanism or hydraulic cylinder piston units to the desired working position, for example to a height of about 2.5 m. After folding one or two side walls in a horizontal position becomes one after open space below the container, which also the appropriate weather protection as part of a mobile filling system and operational reliability over a long period of time guaranteed.

Im Gegensatz zu bekannten Transportern sind im Rahmen der erfindungsgemäßen Einrichtung vorzugsweise zwei Leitungen vorgesehen. Eine dieser Leitungen ist an die Flüssigphase des Speichers angeschlossen, wohingegen die andere in der Gasphase des Speichers endet. In jedem Fall sind beide Leitungen mit der Hochdruckpumpe zur Befüllung der Druckgasbehälter verbunden, sodaß das kryogen verflüssigte Produkt, der Flüssigkeitsvorlauf und das sich durch Verdampfen in der Pumpe entwickelnde Gas über den Gasrückgang zu- und abgeführt werden kann. Durch Zwischenschalten eines Gasabscheiders im Gasrückgang von der Pumpe zum Tank wird der Bereich des intensiven Wärmeüberganges eingeschränkt und der Druckanstieg durch zusätzliche Gasentwicklung im Tank minimiert, sodaß die bei Lagertanks übliche höhere Drucksicherheit vermieden werden kann. Von besonderem Vorteil ist hier eine modulare Bauweise, bei welcher die Hochdruckpumpe als gesonderte Einheit ausgebildet ist und in unmittelbarer Nähe des Speichers für kryogen verflüssigtes Gas aufgestellt werden kann. Bei einer bevorzugten Ausbildung, bei welcher die mit dem Speicher verbundenen Leitungen an eine Hochdruckpumpe angeschlossen sind und das in der Pumpe durch Verdampfen gebildete Gas über einen Gasabscheider rückgeführt wird, befindet sich mit Vorteil eine durch ein Absperrventil abschließbare Verbindung von der Gasphase des Speichers zur Hochdruckleitung der Pumpe. Über diese Verbindung können bei Produktwechsel die Leitungen gespült werden. Die Schlauchleitungen zwischen Füllstation und Speicher können jeweils vakuumisoliert über jeweils totraumlose Kupplungen angeschlossen werden. Die Einrichtung kann durch eine Seilverspannung mit dem Boden auch gegen Kippen gesichert werden.In contrast to known transporters are within the scope of the invention Device preferably provided two lines. One of these lines is connected to the liquid phase of the memory connected, whereas the other in the gas phase of the Memory ends. In any case, both lines are connected to the High pressure pump connected to fill the compressed gas tank, so that the cryogen liquefied product, the liquid flow and the gas evolved by evaporation in the pump the gas drop can be fed in and out. By interposing a gas separator in the gas return from the pump to Tank, the area of intense heat transfer is restricted and the pressure increase due to additional gas development minimized in the tank, so that the higher usual for storage tanks Pressure security can be avoided. Of particular advantage Here is a modular design, in which the high pressure pump is designed as a separate unit and in the immediate vicinity of the storage for cryogenically liquefied gas can. In a preferred embodiment, in which the Storage lines connected to a high pressure pump are and that formed in the pump by evaporation Gas is returned via a gas separator, is located with The advantage of a connection that can be closed by a shut-off valve from the gas phase of the storage to the high pressure line of the pump. The cables can be connected via this connection when changing products be rinsed. The hose lines between the filling station and Storage can each be vacuum-insulated with no dead spaces Couplings can be connected. The facility can be set up by a Rope bracing with the floor also secured against tipping become.

Für das Füllen kann eine frequenzmodulierte Hochdruckpumpe Verwendung finden, welche das kryogen verflüssigte Produkt in den Verdampfer und in die sich anschließenden verteilenden Rohrleitungen drückt. Das Rohrleitungssystem kann hiebei entsprechend ausgebildet sein, sodaß es einen Reingasteil und Mischgasbereich umfaßt, wobei beispielsweise jeder Füllbereich über 120 Füllanschlüsse mit zweimal sechzig Anschlüssen verfügt, damit die Anlage wechselseitig betrieben werden kann. Für den Betrieb der mobilen Anlage ist somit lediglich ein Elektroanschluß erforderlich, wobei für einen Produktwechsel lediglich die Füllstation von der Pumpe bis zu den Füllanschlüssen drucklos gemacht werden muß. In der Folge kann der Speicher an den totraumlosen Kupplungen von der Füllstation getrennt werden und ein anderer Speicher mit der Anlage verbunden werden. Nach erfolgter Verbindungen werden nun die Kupplungen gasseitig geöffnet und das Absperrventil in der Leitung zum Gasraum des Speichers wieder geöffnet, sodaß das Gas zum Verdampfer strömt und an den noch unverschlossenen Füllanschlüsen austritt. Nach einer Analyse, mit welcher bestätigt wird, daß an den Anschlüssen nunmehr zu 100 % reines neues Produkt aus dem Speicher vorliegt, kann eine weitere Füllung mit anderen Gasen erfolgen. A frequency-modulated high-pressure pump can be used for filling find which the cryogen liquefied product in the Evaporator and in the subsequent distributing pipes suppressed. The piping system can accordingly be formed so that there is a clean gas part and mixed gas area includes, for example, each fill area over 120 fill ports with two sixty connections so that the System can be operated alternately. For the operation of the mobile system, all that is required is an electrical connection, only the filling station for a product change be depressurized from the pump to the filling connections got to. As a result, the memory on the dead space clutches be separated from the filling station and another store be connected to the system. After connections the couplings are now opened on the gas side and the shut-off valve opened again in the line to the gas space of the storage facility, so that the gas flows to the evaporator and to the still unsealed Filling connections emerges. After an analysis, with which confirms that the connections are now 100% pure new product from the store can be a further filling with other gases.

Wie in Fig. 3 dargestellt, bilden sodann der Speicher 3 und die Füllstation 2 zwei gesonderte Baueinheiten, wobei die Füllstation 2 beispielsweise mittels hydraulisch ausfahrbarer Stützen 5 in eine Arbeitsposition angehoben werden kann. Entsprechend der Darstellung in Fig. 4 entsteht dadurch unterhalb der Füllstation ein Freiraum für die Flaschenpaletten 6.The invention will now be illustrated schematically in the drawing shown filling system described in more detail. In this shows Fig. 1 shows a truck 1, which transports the filling station 2 and to which a liquefied the storage 3 for cryogen Gas-carrying trailer 4 is coupled. At the Point at which the mobile filling station is now to be set up, the filling station 2 and the memory 3 are discontinued, as in Fig. 2 shown, so that now the unloaded vehicle 1 together can be used with the trailer 4 for other purposes. Then, as shown in Fig. 3, the memory 3 and Filling station 2 two separate units, the filling station 2 for example by means of hydraulically extendable Supports 5 can be raised into a working position. Corresponding the representation in Fig. 4 thus arises below the filling station has a free space for the bottle pallets 6.

Der Boden 11 der Füllstation ist als ausziehbarer Doppelboden für die Befüllanschlüsse ausgeführt. Die gesamte Füllstation kann über Abspannungen 12 gesichert werden. Abweichend von einer derartigen Ausbildung der Füllstation ist es auch möglich, daß die Füllstation in Absetzhöhe belassen wird oder sogar mittels der Teleskopstützen auf eine Höhe knapp oberhalb der Standfläche abgesetzt wird. In diesem Fall werden die Seitenwände zur Schaffung einer Überdachung für die zu befüllenden Gasflaschen nach oben aufgeklappt oder am oberen Rahmen der Füllstation anschlagend in horizontale Position gebracht. The filling station is now shown in more detail in FIG it can be seen that the filling station from a section 7 in which the evaporator technology is housed, and from a section 8 separated therefrom, in which the Plant technology finds space. The side wall 9 of the filling station has been folded down into a horizontal position, so that a large area Canopy for the compressed gas cylinders to be filled arises, which by lateral awning-like curtains 10 a offers a closed, weatherproof work surface. The floor 11 the filling station is a pull-out double floor for the filling connections executed. The entire filling station can over Guy lines 12 are secured. Notwithstanding such Training the filling station, it is also possible that the Filling station is left at drop-off height or even by means of Telescopic supports at a height just above the stand area is discontinued. In this case, the side walls become Creation of a roof for the gas bottles to be filled opened up or on the upper frame of the filling station brought into horizontal position.
