Abstract

An injection circuit with an injection pump (7), an injection duct (6) and a double connecting line to the high-pressure bottle (11) to be filled allows the high-pressure bottle to be filled from an intermediate reservoir (1) or directly from the compressor (2) with no significant heating. The injection circuit dissipates the generated heat either by means of heat exchangers (15) or by mixing in the intermediate reservoir (1). The process is automated by means of a differential pressure switch (9) associated to a temperature sensor on the injection duct (6).

Description

Die vorliegende Erfindung bezieht sich auf eine Gastankstelle mit Zwischenspeicher für das Aufladen von Hochdruck-Speicher flaschen.The present invention relates to a gas filling station with a buffer for the charging of high pressure storage bottles.

In vielen Anwendungen von Druckgas ist die Geschwindigkeit der Aufladung ab Zwischenspeicher (z.B. ab Kompressorspeicher) oder ab Kompressor ein entscheidender funktioneller und wirtschaftlicher Faktor, der durch die Erwärmung durch die Prozesswärme begrenzt wird: so ist z.B. bei der Aufladung von Taucher-Luftflaschen (auf 200 bar) bekannt, dass die aufzufüllende Flasche oft ins Wasser getaucht wird, damit die Füllgeschwindigkeit zunimmt.In many applications of compressed gas, the rate of charging is down Interim storage (e.g. from compressor storage) or from compressor is a crucial one functional and economic factor caused by the warming by the Process heat is limited: for example when charging diving air bottles (at 200 bar) known that the bottle to be filled is often immersed in water, so the filling speed increases.

Betrachtet man innerhalb der Druckgas-Systeme nur die Fülle der Anwendungen von Druckluft (autonome Werkzeuge mit Luft/Öl-Wandler, Antriebe von kleinen Fahrzeugen usw.), findet man immer wieder die gleiche Problematik, oft noch verschärft durch den Energieverlust der Erwärmung, die als grosse Verschwendung empfunden wird oder gar die technisch-wirtschaftliche Anwendung verunmöglicht: wird eine leere Flasche direkt mit einem auf 200 bar gefüllten Zwischenspeicher verbunden, so verursacht der Druckausgleich einen Temperatursprung von über 100 °C in besagter Flasche, was insbesondere bei faserverstärkten Kunststoffbehältern glattweg unzulässig ist.If you only consider the abundance of applications within the compressed gas systems Compressed air (autonomous tools with air / oil converter, drives of small vehicles etc.), one always finds the same problem, often exacerbated by the Energy loss from warming, which is perceived as a great waste or even the technical and economic application is impossible: an empty bottle becomes direct connected to a buffer tank filled to 200 bar, so causes Pressure equalization a temperature jump of over 100 ° C in said bottle, what is inadmissible in particular in the case of fiber-reinforced plastic containers.

Die vorliegende Erfindung hat die Aufgabe eine Einrichtung zu schaffen, die beim Aufladen von Hochdruckflaschen mit Gas die Erwärmung unterbindet.The present invention has for its object to provide a device that Charging high-pressure cylinders with gas prevents heating.

Erfindungsgemäss wird dies dadurch erreicht, dass eine der aufzuladenden Flasche zugeordnete und unter Flaschendruck stehende Spülpumpe über eine Rückleitung das Flaschenvolumen umwälzt und entweder mittels Wärmetauscher oder durch Vermischung mit dem Zwischenspeicher-Inhalt die Temperaturschwankung des Aufladeprozesses begrenzt; zu diesem Zwecke weist die Flasche zwei Anschlüsse auf, die so angeordnet sind, dass beim Umwälzen ein bestmöglicher Volumenaustausch erfolgt.This is achieved according to the invention in that one of the bottles to be charged assigned and pressurized flushing pump via a return line Bottle volume circulates and either by means of heat exchangers or through Mixing with the contents of the buffer store the temperature fluctuation of the Charging process limited; for this purpose the bottle has two connections, which are arranged in such a way that the best possible volume exchange during circulation he follows.

Ausführungsbeispiele des Erfindungsgegenstandes und seine Funktionsweise werden nachstehend anhand der Fig. 1 bis 3 erläutert, wobei:

  • Fig. 1 ein Ladesystem mit Vermischung darstellt, in
  • Fig. 2 ein Ladesystem mit Wärmetauscher zu sehen ist, und in
  • Fig. 3 eine spülfähige Flasche im Schnitt mit einer typischen Anwendung in Form einer Schrankenbetätigung verbunden ist.
    • Exemplary embodiments of the subject matter of the invention and its mode of operation are explained below with reference to FIGS. 1 to 3, in which:
  • 1 shows a charging system with mixing, in
  • Fig. 2 shows a charging system with a heat exchanger, and in
  • Fig. 3 is a flushable bottle in section with a typical application in the form of a barrier actuation.

    • In Fig.1 besteht die Gastankstelle mit Vermischung aus einem Zwischenspeicher 1 der durch einen hier nicht genauer definierten Hochdruckkompressor 2 auf einem vorgegebenen Betriebsdruck gehalten wird, aus einer Drosselblende 3, die die Geschwindigkeit der Aufladung bestimmt, und aus einer speiseseitigen Schnellkupplungshälfte 4 auf der Speiseleitung 5. So weit wie sinnvoll vom Speiseausgang entfernt mündet die Spülleitung 6 in den Zwischenspeicher 1, die über die Spülpumpe 7 mit der spülseitigen Schnellkupplungshälfte 8 verbunden ist. Die Spülpumpe 7 ist zusammen mit ihrem Antrieb in einem unter Flaschendruck stehenden Druckbehälter 10 untergebracht. Ein Differenzdruckschalter 9 als Steuerung der Spülpumpe 7 überbrückt die Drosselblende 3, ein Temperaturfühler 14 an der Spülleitung 6 dient der Automatisierung des Ladevorganges. Die Flaschenseite des Ladesystems besteht aus der durchspülbaren Flasche 11 (hier als Energiespeicher eines Gabelstaplers dargestellt) mit 2 Anschlüssen, die jeweils mit der speiseseitigen 12 und spülseitigen 13 Schnellkupplungshälfte verbunden sind.In Figure 1, the gas filling station with mixing consists of an intermediate storage 1 by a high-pressure compressor 2 on a not defined here predetermined operating pressure is maintained from a throttle orifice 3, which Charging speed is determined, and from a food side Quick coupling half 4 on the feed line 5. As far as possible from Feed outlet away, the flush line 6 opens into the buffer 1, which via the Flushing pump 7 is connected to the quick coupling half 8 on the flushing side. The Flushing pump 7, together with its drive, is in a bottle pressure Pressure vessel 10 housed. A differential pressure switch 9 to control the Flushing pump 7 bridges the orifice 3, a temperature sensor 14 on the Flushing line 6 is used to automate the charging process. The bottle side of the Charging system consists of the flushable bottle 11 (here as an energy storage device) Forklift shown) with 2 connections, each with the feed side 12 and flush-side 13 quick coupling half are connected.

    Wird der unter Hochdruck stehende Zwischenspeicher 1 über das Schnellkupplungssystem 4/8/12/13 mit der aufzuladenden Flasche 11 verbunden, strömt Gas dosiert durch die Blende 3 in die Flasche 11, solange ein Druckabfall zwischen den zwei Behältern existiert. Währenddem dieser Druckabfall besteht, wird er den Differenzdruckschalter 9 an der Drosselblende 3 offen halten. Erst wenn der Druckausgleichsprozess beendet ist, d.h. wenn der Inhalt der Flasche 11 erwärmt ist und der Inhalt des Zwischenspeichers 1 kühler ist, schaltet der Differenzdruckschalter 9 die Spülpumpe 7 zu, die den Wärmeaustausch zwischen der Flasche 11 und dem Zwischenspeicher 1 durch Vermischen besorgt. Der Temperaturfühler 14 stellt die Spülpumpe 7 ab, sobald das durch die Spülleitung 6 strömende Gas annähernd die Umgebungstemperatur erreicht hat. Is the high-pressure buffer 1 on the Quick coupling system 4/8/12/13 connected to the bottle 11 to be charged flows Gas doses through the orifice 3 in the bottle 11 as long as there is a pressure drop between the two containers exist. While this pressure drop persists, it becomes the Keep differential pressure switch 9 on throttle orifice 3 open. Only when the Pressure equalization process is complete, i.e. when the contents of the bottle 11 are warmed and the content of the buffer 1 is cooler, the differential pressure switch 9 switches the Flushing pump 7 to the heat exchange between the bottle 11 and Buffer 1 worried by mixing. The temperature sensor 14 provides the Flushing pump 7 as soon as the gas flowing through the flushing line 6 approximately Has reached ambient temperature.

    Die Spülpumpe 7 muss also nur die Druckabfälle der Leitungen und Kupplungen überwinden, da sinnvollerweise die Drosselstelle 3 als differenzdruckgesteuerter Stromregler ausgestaltet wird, der also bei Druckausgleich voll öffnet; somit wird auch der Druckausgleichsvorgang beschleunigt, der ja der Erwärmungsphase der Flasche 11 entspricht: diese soll so kurz wie möglich sein, damit so wenig Wärme wie möglich in die Flaschenwand eindringt.The flushing pump 7 therefore only has to reduce the pressure drops in the lines and couplings overcome, since the throttle 3 makes sense as differential pressure controlled Current controller is designed, which opens fully when pressure equalization; thus also the pressure equalization process accelerates the heating phase of the bottle 11 corresponds to: this should be as short as possible so that as little heat as possible enters the Bottle wall penetrates.

    Die zeitliche Trennung von Druckausgleich und Wärmeausgleich existiert bei der Gastankstelle mit Wärmetauscher der Fig. 2 nicht: den gleichen Elementen 1' bis 14' wie bei der Gastankstelle mit Vermischung wird ein Wärmetauscher 15 zugefügt, der im Zwischenspeicher 1' vornehmlich an die Spülleitung 6' angeschlossen ist und dessen Ausgang über die Leitung 16 mit der speiseseitigen Schnellkupplungshälfte 4' verbunden ist; somit wird der Wärmeaustausch während der Aufladung möglich, denn simultan zum Überströmen des Gases vom Zwischenspeicher 1' in die Flasche 11' über das Schnellkupplungssystem 4'/8'/12'/13' wird durch das Umwälzen der Temperaturausgleich vorgenommen: sobald die Flasche 11' an den Zwischenspeicher 1' gekoppelt wird, schaltet hier der Differenzdruckschalter 9' die Spülpumpe 7' zu und den Wärmetauscher-Ventilator 17 ein (auf den Ventilator 17 kann verzichtet werden, falls der Wärmetauscher 15 so im Zwischenspeicher 1' angeordnet wird, dass er durch die austretenden Gase durchströmt wird): auch hier ist der Vorgang abgeschlossen, sobald der Temperaturfühler 14' keinen wesentlichen Unterschied mehr zur Umgebungstemperatur feststellt und die Spülpumpe 7' ausschaltet.
    Die Ladung mit Umwälzung durch Wärmetauscher verhindert den Wärmeaufbau in der Flasche 11' zu jedem Zeitpunkt und schont damit wärmeempfindliche Bauarten; unentbehrlich ist das System beim Aufladen direkt ab Kompressor und wenn es nicht bis zum vollständigen Druckausgleich kommt (Teilladung: die Spülpumpe 7 kann infolge des bleibenden Druckunterschiedes nicht eingeschaltet werden). Bei grossen Zwischenspeicher kann (und bei direkter Kompressoraufladung muss) der Wärmetauscher 15' ausserhalb der Anlage angeordnet werden, z.B. im Erdreich. Schliesslich sei darauf hingewiesen, dass sowohl für das Vermischungssystem wie auch für die Ausführung mit Wärmetauscher die gleichen Flaschenarten zum Einsatz kommen.    2 does not exist for the gas filling station with heat exchanger of FIG. 2: the same elements 1 'to 14' as for the gas filling station with mixing, a heat exchanger 15 is added, which in the intermediate store 1 'primarily to the flushing line 6' is connected and its output is connected via line 16 to the quick coupling half 4 'on the feed side; This enables heat exchange during charging, because simultaneously with the overflow of the gas from the intermediate store 1 'into the bottle 11' via the quick coupling system 4 '/ 8' / 12 '/ 13', the temperature compensation is carried out by circulating: as soon as the bottle 11 'is coupled to the intermediate store 1', here the differential pressure switch 9 'switches on the flushing pump 7' and the heat exchanger fan 17 (the fan 17 can be dispensed with if the heat exchanger 15 is arranged in the intermediate store 1 'in such a way that it through which the escaping gases flow): here too the process is complete as soon as the temperature sensor 14 'no longer detects any significant difference from the ambient temperature and the flushing pump 7' switches off.
    The charge with circulation through heat exchangers prevents the heat build-up in the bottle 11 'at all times and thus protects heat-sensitive designs; The system is indispensable when charging directly from the compressor and if there is no full pressure equalization (partial charge: the flushing pump 7 cannot be switched on due to the permanent pressure difference). In the case of large intermediate stores, the heat exchanger 15 'can be arranged outside the system (and in the case of direct compressor charging, for example, in the ground). Finally, it should be pointed out that the same bottle types are used both for the mixing system and for the version with a heat exchanger.

    Fig 3 zeigt einen Schnitt durch eine handelsübliche Gasflasche 18, die durch einen zweiten Anschluss mit Rohrfortsatz 19 in einen spülbaren Speicher umgewandelt ist, der durch die Schnellkupplungen 12"/13" mit dem Ladesystem verbunden werden kann; als einfache Anwendung für Luft als Gas ist hier eine Betätigung für die Schranke 23 dargestellt, die über das Druckreduzierventil 20 und das Steuerventil 21 mittels einfachwirkendem Zylinder 22 bewegt wird. Im Zylinder 22 ist eine Doppelkammer 24 (schraffiert) mit Öl gefüllt, wodurch die Bewegung über das Drosselventil 25 gebremst werden kann, und die Anforderungen an den Schalldämpfer 26 bescheiden bleiben.Fig. 3 shows a section through a commercially available gas bottle 18, through a second connection with pipe extension 19 is converted into a flushable memory can be connected to the charging system by the quick couplings 12 "/ 13"; as A simple application for air as gas is an actuation for the barrier 23 shown, by means of the pressure reducing valve 20 and the control valve 21 single-acting cylinder 22 is moved. There is a double chamber 24 in the cylinder 22 (hatched) filled with oil, which brakes the movement via the throttle valve 25 can be, and the requirements for the silencer 26 remain modest.
