Description

Die Erfindung betrifft eine Vorrichtung zum Bereitstellen eines Gases, das in Behältern in flüssiger Form oder zusammen mit einem in einer porösen Masse verteilten Lösungsmittel unter Druck gespeichert ist, wobei jeder Behälter mit einer Gasfüll- und Gasentnahmevorrichtung vorgesehen ist, wobei eine Heizvorrichtung vorgesehen ist und wobei die Behälter so in eine allseitig geschlossene und möglichst luftdichte Kapsel eingebaut sind.The invention relates to a device for providing a gas, which is stored in containers in liquid form or together with a solvent distributed in a porous mass under pressure, each container being provided with a gas filling and gas extraction device, a heating device being provided and wherein the containers are installed in a capsule that is closed on all sides and as airtight as possible.

Eine derartige Vorrichtung ist in der DE-A-26 50 880 beschrieben. Die Behälter sind dabei in Transportbehältern (Containern) oder in ortsgebundenen Räumen aufgestellt und werden beheizt, um eine bestimmte Entnahmemenge an gespeichertem Gas pro Zeiteinheit garantieren zu können. Unter dem Gesichtspunkte einer weitgehenden Entleerung der Behälter und der Garantie einer bestimmten Entnahmemenge pro Zeiteinheit ist eine möglichst hohe Temperatur erstrebenswert. Die Erwärmung der Behälter auf eine relativ hohe Temperatur führt aber zu einem hohen Energieverbrauch verbunden mit beträchtlichen Heizkosten.Such a device is described in DE-A-26 50 880. The containers are set up in transport containers or in local spaces and are heated in order to guarantee a certain amount of gas stored per unit of time. From the point of view of extensive emptying of the containers and the guarantee of a certain withdrawal quantity per unit of time, the highest possible temperature is desirable. However, heating the containers to a relatively high temperature leads to high energy consumption combined with considerable heating costs.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs erwähnten Art anzugeben, die nur geringe Heizkosten verursacht, durch die jedoch eine weitgehende Entleerung der Behälter nicht beeinträchtigt wird und weiterhin eine bestimmte Entnahmemenge pro Zeiteinheit garantiert ist.The invention is therefore based on the object of specifying a device of the type mentioned at the outset which causes only low heating costs, but which does not impair extensive emptying of the containers and which also guarantees a certain removal quantity per unit of time.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass sich nur die gasdichten Gehäuse der Behälter und die Heizvorrichtung innerhalb der Kapsel befinden, so dass der Innenraum der Kapsel minimal wird, während die Gasfüll- und Gasentnahmevorrichtungen im belüfteten Aussenraum der Kapsel angeordnet sind.According to the invention, this object is achieved in that only the gas-tight housing of the containers and the heating device are located inside the capsule, so that the interior of the capsule is minimal, while the gas filling and gas extraction devices are arranged in the ventilated outer space of the capsule.

Erfindungsgemäss werden die Behälter zunächst in eine Kapsel montiert. Dies ist so gestaltet, dass einerseits sicherheitstechnische Aspekte berücksichtigt werden und andererseits der zu beheizende Raum möglichst klein gehalten wird. Dabei wurde von folgender Erkenntnis ausgegangen: Der Heizenergieaufwand bei der Entnahme von Gasen aus Flaschen setzt sich hauptsächlich aus folgenden Energiebeiträgen zusammen:

  • 1. Energie für die Entlösung eines Gases aus einem Lösungsmittel, in dem das Gas gelöst ist, wobei das Gas zusammen mit dem Lösungsmittel in einer porösen Masse unter Druck verteilt ist bzw. Energie für die Verdampfung eines flüssig gespeicherten Gases.
  • 2. Energie, die erforderlich ist, um Wärmeverluste durch die Wände des beheizten Raumes auszugleichen.
  • 3. Energie, um die Wärmeverluste auszugleichen, die durch den aus sicherheitstechnischen Gründen vorgeschriebenen Luftwechsel entstehen. Diese Luftwechsel sind erforderlich, um die Bildung von zündfähigen Gas-Luft-Gemischen durch Gas, das durch Undichtigkeiten austritt, zu vermeiden.
According to the invention, the containers are first assembled in a capsule. This is designed so that safety aspects are taken into account on the one hand and the space to be heated is kept as small as possible on the other. The following knowledge was taken as a basis: The heating energy expenditure when removing gases from bottles is mainly composed of the following energy contributions:
  • 1. Energy for the detachment of a gas from a solvent in which the gas is dissolved, the gas being distributed together with the solvent in a porous mass under pressure or energy for the vaporization of a liquid stored gas.
  • 2. Energy that is required to compensate for heat losses through the walls of the heated room.
  • 3. Energy to compensate for the heat losses caused by the air change required for safety reasons. These air changes are necessary to avoid the formation of ignitable gas-air mixtures by gas that escapes through leaks.

Erfindungsgemäss werden die Behälter, in denen Gas zusammen mit einem in einer porösen Masse verteilten Lösungsmittel unter Druck gespeichert sind oder in denen das Gas in flüssiger Form gespeichert ist, vor der Gasentnahme in einer Kapsel eingeschlossenen, durch die zwei Zonen gebildet werden. In der ersten Zone (Zone I), dem Kapselinnernraum, befinden sich ausschliesslich die Teile der Behälter, in deren Bereich keine Undichtigkeiten, d.h. Gaslecks, auftreten können. Der gasdichte Teil eines Behälters ist das Behältergehäuse mit Ausnahme der Gasentnahme- bzw. Gasfüllstelle. Dieser Bereich jedes Behälters befindet sich in der zweiten Zone ausserhalb der Kapsel (Zone 11). Hierbei können alle Behälter in einer Kapsel oder ein Teil der Behälter in jeweils eine Kapsel eingebaut werden. Nachdem die Behälter in dieser Weise in eine oder mehrere Kapseln eingebaut worden sind, kann den Behältern Gas entnommen werden. Hierbei wird der Kapselinnenraum geheizt, während der Aussenraum belüftet wird.According to the invention, the containers in which gas is stored under pressure together with a solvent distributed in a porous mass or in which the gas is stored in liquid form are enclosed in a capsule before the gas withdrawal, through which two zones are formed. In the first zone (Zone I), the interior of the capsule, there are only the parts of the container in whose area there are no leaks, i.e. Gas leaks can occur. The gas-tight part of a container is the container housing with the exception of the gas extraction or gas filling point. This area of each container is in the second zone outside the capsule (zone 11). All containers can be installed in one capsule or some of the containers in one capsule. After the containers have been installed in one or more capsules in this way, gas can be removed from the containers. The interior of the capsule is heated while the exterior is being ventilated.

Durch diese Massnahme, insbesondere die Trennung in zwei Zonen, wird folgendes erreicht:This measure, in particular the separation into two zones, achieves the following:

Für die Gasentnahme ist es nur erforderlich, Zone I zu beheizen. Im Unterschied zu den bekannten Verfahren muss diese Zone nicht mehr belüftet werden, da innerhalb dieser Zone keine lösbaren Verbindungen, d.h. keine Schläuche, Armaturen und Leitungen untergebracht sind, in deren Bereich Undichtigkeiten auftreten können. Da es erfindungsgemäss unnötig ist, beheizte Luft zu wechseln, wird der unter Punkt 3 angegebene Energiebeitrag, der ein wesentlicher Heizkostenfaktor ist, auf ein Minimum reduziert. Gelingt es, die Kapselung der Behälter möglichst luftdicht vorzunehmen, so kann der auf Luftwechsel beruhende Wärmeverlust vollständig ausgeschaltet werden.It is only necessary to heat Zone I for gas extraction. In contrast to the known methods, this zone no longer needs to be ventilated, since within this zone there are no detachable connections, i.e. there are no hoses, fittings and lines in the area where leaks can occur. Since, according to the invention, it is unnecessary to change heated air, the energy contribution specified in point 3, which is a significant heating cost factor, is reduced to a minimum. If the containers can be encapsulated as airtight as possible, the heat loss due to air exchange can be completely eliminated.

Wurden die Behälter bisher z.B. in grossen Transportbehältern geliefert und während der Entnahme beheizt, so ist das erfindungsgemäss zu beheizende Volumen, d.h. der Kapselinnenraum, vergleichsweise klein. Daher ist die Oberfläche des beheizten Raumes (der Kapsel) kleiner als bisher, wodurch die unter Punkt 2 angeführten Wärmeverluste über die Wände des beheizten Raumes reduziert werden können. Diese Verluste können durch die Verwendung einer Kapsel, deren Wand mit wärmeisolierendem Material beschichtet ist oder die aus einem derartigen Material besteht, ebenfalls weitgehend ausgeschaltet werden.If the containers were previously e.g. Delivered in large transport containers and heated during removal, the volume to be heated according to the invention, i.e. the capsule interior, comparatively small. Therefore, the surface of the heated room (the capsule) is smaller than before, which means that the heat losses mentioned under point 2 over the walls of the heated room can be reduced. These losses can also be largely eliminated by using a capsule whose wall is coated with heat-insulating material or which consists of such a material.

Erfindungsgemäss ist es möglich, die in eine Kapsel eingebauten Behälter im Freien oder in einem Raum aufzustellen. Bei einer Gasentnahme im Freien wäre dabei unter dem Gesichtspunkt möglichst geringer Wärmeverluste durch Wärmeleitung eine gute Isolierung der gesamten Kapsel wichtig. Werden die Behälter dagegen in einem Raum, z.B. in einem mobilen Container untergebracht, ist es nur erforderlich, die Teile der Kapsel, die sich an einer Aussenwand des Raumes befinden, mit einem gut wärmeisolierenden Material zu versehen, während das Isoliervermögen der zur Innenseite des Raumes weisenden Wände geringer sein kann.According to the invention, it is possible to set up the containers installed in a capsule outdoors or in a room. When gas is extracted outdoors, it would be important to insulate the entire capsule from the point of view of minimizing heat loss through heat conduction. If, on the other hand, the containers are accommodated in a room, for example in a mobile container, it is only necessary to provide the parts of the capsule which are on an outer wall of the room with a good heat-insulating material, while the insulating capacity of the Walls facing inside the room may be less.

Nach einem Merkmal der Erfindung befinden sich in Zone Hatte die Teile des Behälters bzw. der Entnahmevorrichtung, in deren Bereich Undichtigkeiten auftreten können. Diese Zone wird daher belüftet. Es ist jedoch nicht notwendig, Zone II zu beheizen, so dass auf diese Weise keine Heizenergie verlorengeht.According to a feature of the invention, the parts of the container or of the removal device are located in zone H, in the area of which leaks can occur. This zone is therefore ventilated. However, it is not necessary to heat Zone II, so that no heating energy is lost.

Mit dem erfindungsgemässen Verfahren kann der Heizkostenaufwand auf einen Bruchteil der bisher anfallenden Kosten gesenkt werden.With the method according to the invention, the heating costs can be reduced to a fraction of the previously incurred costs.

Beim Befüllen von Acetylenflaschen z.B. werden die Flaschen während des Füllvorganges mit Kühlwasser gekühlt. Durch die Kapselung ist es möglich, das Kühlwasser wirksamer als bisher an die Flaschen heranbringen zu können. Ausserdem wird durch die Trennung erreicht, dass die Leitungen nicht mit Wasser in Berührung kommen und somit die Korrosion nicht gefördert wird.When filling acetylene bottles e.g. the bottles are cooled with cooling water during the filling process. The encapsulation makes it possible to bring the cooling water to the bottles more effectively than before. In addition, the separation ensures that the pipes do not come into contact with water and thus corrosion is not promoted.

In einer Ausgestaltung des Erfindungsgedankens sind mit Vorteil in einer Kapsel jeweils alle über eine gemeinsame Entnahmeleitung zu einer Bündeleinheit zusammengefassten Behälter angeordnet. Sind die Behälter in mehreren Kapseln montiert, können die Kapseln in dieser Anordnung jeweils getrennt voneinander beheizt werden und die Behälter dieser Kapsel unabhängig von den übrigen Behältern entleert werden.In one embodiment of the inventive concept, all of the containers combined into a bundle unit via a common removal line are advantageously arranged in one capsule. If the containers are mounted in several capsules, the capsules can be heated separately in this arrangement and the containers of this capsule can be emptied independently of the other containers.

Nach einem weiteren Merkmal der Erfindung kann die Heizvorrichtung vorteilhafterweise ein unterhalb der Behälter in der Kapsel angeordneter Lufterhitzer sein. Z.B. kann ein Wärmetauscher mit Rippenrohren, durch die Warmwasser, Heisswasser oder Dampf strömt und dabei die Rohre umspülende Luft erwärmt, Verwendung finden. Die Luft innerhalb des Kapselinnenraums kann umgewälzt werden. Die Umwälzung kann durch geeignete Vorrichtungen erzwungen werden. Üblicherweise reicht jedoch die durch Temperaturunterschiede innerhalb einer Kapsel verursachte Wärmekonvektion aus. Durch diese Massnahme wird ein Wärmestau im Bereich der Kapseldecke verhindert. In einer vorteilhaften Variante dieser Vorrichtung ist im Kapselinnenraum eine Wand mit Abstand und im wesentlichen parallel zu einer vertikalen Kapselwand angeordnet, wobei der zwischen der Wand und der vertikalen Kapselwand gebildete Raum den Bodenbereich der Kapsel mit dem Deckenbereich der Kapsel verbindet. Dabei sind in diesem Raum keine Behälter angeordnet. Die erwärmte Luft strömt hierbei durch den thermischen Auftrieb zwischen den Flaschenlücken vom Bereich des Kapselbodens zum Bereich der Kapseldecke. Aus diesem Bereich strömt die abgkühlte Luft über den zwischen Kapselwand un der weiteren Wand gebildeten Zwischenraum zurück. Die weitere Wand verhindert, dass sich die über den Heizkörpern emporströmende Luft mit der kühleren Luft mischt.According to a further feature of the invention, the heating device can advantageously be an air heater arranged below the container in the capsule. E.g. a heat exchanger with finned tubes, through which hot water, hot water or steam flows and which heats air flowing around the tubes, can be used. The air inside the capsule interior can be circulated. The circulation can be forced by suitable devices. Usually, however, the heat convection caused by temperature differences within a capsule is sufficient. This measure prevents heat build-up in the capsule area. In an advantageous variant of this device, a wall is arranged in the interior of the capsule at a distance and essentially parallel to a vertical capsule wall, the space formed between the wall and the vertical capsule wall connecting the bottom region of the capsule to the ceiling region of the capsule. No containers are arranged in this room. The heated air flows through the thermal buoyancy between the bottle gaps from the area of the capsule bottom to the area of the capsule top. From this area, the cooled air flows back through the space formed between the capsule wall and the further wall. The further wall prevents the air flowing over the radiators from mixing with the cooler air.

Im folgenden soll anhand schematischer Skizzen ein Ausführungsbeispiel einer erfindungsgemässen Vorrichtung beschrieben werden:

  • Es zeigen:
  • Figur 1 ein Schnittbild einer schematisch dargestellten erfindungsgemässen Vorrichtung
  • Figur 2 eine Ausgestaltung einer in einem mobilen Container eingebauten erfindungsgemässen Vorrichtung.
An exemplary embodiment of a device according to the invention is to be described below with the aid of schematic sketches:
  • Show it:
  • Figure 1 is a sectional view of a schematically illustrated device according to the invention
  • Figure 2 shows an embodiment of an inventive device installed in a mobile container.

In Figur 1 sind vier Flaschen 1 bis 4 dargestellt. Die Behälter stehen auf einer gelochten Bodenplatte 5, unterhalb deren zwei Heizkörper 6 angeordnet sind. Die Behälter 1 bis 4 sind von einer aus fünf Wänden bestehenden Kapsel umgeben. In der Figur sind lediglich die beiden Seitenwände 7, 8 und die Decke 9 dargestellt. DieBehälter werden vor der Gasentnahme so in diese Kapsel montiert, dass lediglich die Behältergehäuse innerhalb der Kapsel angeordnet sind, während die jeweiligen Flaschenventile 10 bis 13, Schläuche 14 bis 17 sowie die gemeinsame Entnahmeleitung 18 ausserhalb der Kapsel untergebracht sind. Zusammen mit dem Raum, in dem die Heizkörper 6 angeordnet sind, bildet die Kapsel einen geschlossenen, im wesentlichen luftdichten Raum. Das Material, aus dem die Kapselwände gefertigt werden, besitzt gute wärmeisolierende Eigenschaften.In Figure 1, four bottles 1 to 4 are shown. The containers stand on a perforated base plate 5, below which two radiators 6 are arranged. The containers 1 to 4 are surrounded by a capsule consisting of five walls. In the figure, only the two side walls 7, 8 and the ceiling 9 are shown. Before the gas is withdrawn, the containers are mounted in this capsule such that only the container housings are arranged inside the capsule, while the respective bottle valves 10 to 13, hoses 14 to 17 and the common extraction line 18 are accommodated outside the capsule. Together with the space in which the radiators 6 are arranged, the capsule forms a closed, essentially airtight space. The material from which the capsule walls are made has good heat-insulating properties.

Nachdem die Behälter 1 bis 4 auf die geschilderte Weise in einer Kapsel eingebaut worden sind, kann den Behältern Gas, im Ausführungsbeispiel Azetylen, das zusammen mit einem in einer porösen Masse verteilten Lösungsmittel unter Druck in den Behältern gespeichert ist, entnommen werden. Während der Gasentnahme werden die Behälter beheizt, um die zur Entnahme erforderlichen Lösungs-, Absorptions- und/oder Verdampfungswärme aufzubringen. In der Zeichnung ist eine Regeleinheit, über die die Temperatur des Kapselinnenraums in Abhängigkeit vom Behälterdruck geregelt werden kann, nicht dargestellt. Durch eine derartige Regelung ist es möglich, bei vollen Behältern eine niedrige Temperatur innerhalb der Kapsel, mit sinkendem Druck in den Behältern jedoch eine höhere Temperatur einzustellen. Im Zusammenhang mit dem Einbau der Behälter in eine Kapsel führt diese Massnahme zu einer überraschend grossen Heizkostenersparnis. Musste bisher für die Entleerung von Behältern, die in mobilen Containern montiert waren und in diesen erwärmt wurden, ein Heizenergieverbrauch veranschlagt werden, der etwa dem eines Einfamilienhauses während der Heizperiode entsprach, so sinkt der Energieverbrauch einer erfindungsgemässen Vorrichtung auf 10% bis 20% dieses Wertes.After the containers 1 to 4 have been installed in a capsule in the manner described, gas, in the exemplary embodiment acetylene, which is stored together with a solvent distributed in a porous mass under pressure in the containers, can be removed from the containers. During the gas extraction, the containers are heated in order to apply the heat of solution, absorption and / or evaporation required for the extraction. The drawing does not show a control unit by means of which the temperature of the interior of the capsule can be regulated as a function of the container pressure. Such a regulation makes it possible to set a low temperature inside the capsule when the containers are full, but to set a higher temperature as the pressure in the containers decreases. In connection with the installation of the containers in a capsule, this measure leads to a surprisingly large saving in heating costs. Until now, heating energy consumption that corresponded to that of a family home during the heating period had to be estimated for the emptying of containers which were mounted in mobile containers and were heated in them, so the energy consumption of a device according to the invention drops to 10% to 20% of this value .

Durch die Heizkörper 6 erwärmte Luft streicht durch die gelochte Bodenplatte 5 und zwischen den Behältern 1 und 2 bzw. 3 und 4 empor. Im Wärmekontakt mit den Behältern kühlt die Luft etwas ab und fliesst zwischen den Flaschen 1 bzw. 4 und den Kapselwänden 7 bzw. 8 sowie zwischen den Behältern 2 und 3 zu den Heizkörpern 6 zurück. Dieser Skizze ist zu entnehmen; dass der Kapselinnenraum möglichst klein zu halten ist.Air heated by the radiator 6 sweeps up through the perforated base plate 5 and between the containers 1 and 2 or 3 and 4. The air cools somewhat in thermal contact with the containers and flows back to the radiators 6 between the bottles 1 and 4 and the capsule walls 7 and 8 and between the containers 2 and 3. This sketch can be seen; that the interior of the capsule should be kept as small as possible.

Sind die auf die beschriebene Weise montierten Behälter innerhalb eines Raumes angeordnet, ist es erforderlich, den Aussenraum der Kapsel, in dem die Behälterventile 10 bis 13, die Schläuche 14 bis 17 sowie die gemeinsame Entnahmeleitung 18 untergebracht sind, zu belüften.If the containers assembled in the manner described are arranged within a space, the outer space of the capsule, in which the container valves 10 to 13, the hoses, is required 14 to 17 and the common sampling line 18 are housed to vent.

In Figur 2 ist eine erfindungsgemässe Vorrichtung dargestellt, bei der sich die Behälter 1 , 2, 1 ', 2' innerhalb eines mobilen Containers 20 befinden. Die Behälter sind zu zwei Gruppen 1 bis 2 und 1' bis 2' zusammengefasst, die jeweils in eine eigene Kapsel eingeschlossen sind. Die beiden Gruppen sind rechts und links von einem begehbaren Mittelgang 22 angeordnet. EineAussenwand 8,8' der Kapseln fällt jeweils mit einer der Containerwände zusammen und ist daher nach Möglichkeit besonders gut gegen Wärmeverluste zu isolieren. In der Containerdecke befindet sich eine Lüftungsöffnung 21. Bei herkömmlichen Vorrichtungen wurde das gesamte Containervolumen beheizt und zusätzlich der gesamte Luftinhalt mehrmals pro Stunde (ca. 3 mal) gewechselt. Erfindungsgemäss wird der Containerinnerraum in zwei Zonen geteilt. Dabei wird nur die durch die Kapselwände 7 bis 9 bzw. 7' bis 9' gebildete Zone I (Kapselinnenraum) beheizt. In dieser Zone wird jedoch kein Luftwechsel vorgenommen. Dem Aussenbereich der beiden Kapseln (Zone 11) wird erfindungsgemäss keine Wärme zugeführt, dagegen wird dieser Bereich belüftet.FIG. 2 shows a device according to the invention in which the containers 1, 2, 1 ', 2' are located within a mobile container 20. The containers are combined into two groups 1 to 2 and 1 'to 2', each of which is enclosed in its own capsule. The two groups are arranged to the right and left of an accessible central aisle 22. An outer wall 8, 8 'of the capsules coincides with one of the container walls and is therefore, if possible, particularly well insulated against heat loss. There is a ventilation opening 21 in the container ceiling. In conventional devices, the entire container volume was heated and, in addition, the entire air content was changed several times per hour (approx. 3 times). According to the container interior is divided into two zones. Only zone I (interior of the capsule) formed by the capsule walls 7 to 9 or 7 'to 9' is heated. However, there is no air change in this zone. According to the invention, no heat is supplied to the outer area of the two capsules (zone 11), but this area is ventilated.

In Figur 2 ist strichpunktiert eine Variante einer erfindungsgemässen Vorrichtung eingetragen. Demnach wird zwischen den Kapselwänden 7 bis 7' und den zugehörigen Behältern 1 bzw. 2' eine zusätzliche Wand 19 bzw. 19' mit Abstand und parallel zu den Kapselwänden 7 bzw. 7' montiert. Durch die zusätzlichen Wände 19 bzw. 19' wird eine Umwälzung der Luft innerhalb der beiden Kapseln gefördert. Die durch Heizkörper 6 erwärmte Luft streicht zwischen den Behältern 1 und 2 bzw. 1' und 2' empor, kühlt dabei ab und wird aus dem Bereich der Kapseldecke über den Raum zwischen der Kapselwand 7 und der zusätzlichen Wand 19 (7' und 19' in den Bodenbereich der Kapsel geleitet.A variant of a device according to the invention is shown in broken lines in FIG. Accordingly, an additional wall 19 or 19 'is mounted between the capsule walls 7 to 7' and the associated containers 1 and 2 'at a distance and parallel to the capsule walls 7 and 7'. A circulation of the air within the two capsules is promoted by the additional walls 19 and 19 '. The air heated by the radiator 6 sweeps up between the containers 1 and 2 or 1 'and 2', cools down and is removed from the area of the capsule ceiling via the space between the capsule wall 7 and the additional wall 19 (7 'and 19' directed into the bottom area of the capsule.

Zusammenfassend lässt sich feststellen, dass durch die erfindungsgemässe Vorrichtung eine erhebliche Senkung des Heizenergiebedarfs erzielt werden kann.In summary, it can be stated that the device according to the invention can achieve a significant reduction in the heating energy requirement.
