Durch das Verfahren zum Reinigen von Gas nach der Erfindung wird das im Druckbehälter abgefüllte Gas in dem Druckbehälter selbst einer Nachreinigung unterzogen. Dadurch kann auf externe Reiniger verzichtet werden. Damit werden fehlerhafte Eingriffe bei und nach der Montage ausgeschlossen. Da das Reinigungsmaterial immer nur von dem im Druckbehälter abgefüllten Gas durchströmt wird, können Spülvorgänge entfallen.By the method for purifying gas according to the invention will be that in pressure vessel bottled Gas in the pressure vessel even subjected to a post-purification. This can be done on external Cleaners are dispensed with. This will contribute to erroneous interventions and excluded after assembly. Because the cleaning material always only from that in the pressure vessel bottled Gas flows through will, can Rinses omitted.
Erfindungsgemäß wird ein Eindringen des Reinigungsmaterials in die zum Verbraucher führenden Strömungswege des Gases und die im Strömungsweg angeordneten Armaturen verhindert.According to the invention is a Penetration of the cleaning material in the leading to the consumer flow paths of the gas and those in the flow path arranged fittings prevented.
Das Verfahren zur Gasreinigung wird im allgemeinen bei Temperaturen unter 100°C durchgeführt. Vorteilhaft sind Temperaturen, bei denen das Reinigungsmaterial wirksam ist.The Process for gas purification is generally at temperatures below 100 ° C carried out. Advantageous are temperatures at which the cleaning material is effective.
Vorteilhaft sind Temperaturen in Bereich von 0°C bis 80°C, insbesondere bei Raumtemperatur oder Temperaturen im Bereich von 20 bis 30°C.Advantageous are temperatures in the range of 0 ° C to 80 ° C, especially at room temperature or Temperatures in the range of 20 to 30 ° C.
Ein Reinigungsmaterial zum Reinigen von Gas bildet die Grundlage zur Druchführung des Verfahrens, wobei die teilweise Anordnung des Reinigungsmaterials in der Absperrarmatur und zwar in der zum Ventilsitz führenden Bohrung der Absperrarmatur durch die Erfindung nicht ausgeschlossen wird.One Cleaning material for cleaning gas forms the basis for Druchführung of the method, wherein the partial arrangement of the cleaning material in the shut-off valve and in the leading to the valve seat Bore the shut-off valve is not excluded by the invention.
Reinigungsmaterial sind für die Gasreinigung übliche Materialien wie Silika-Gel, Molekularsieb, Aktivkohle, Adsorptionsmittel, Absorptionsmittel, Adsorberharze oder Absorberharze.cleaning material are for the gas cleaning usual Materials such as silica gel, molecular sieve, activated charcoal, adsorbent, Absorbents, adsorber resins or absorber resins.
Als Reinigungsmittel geeignete Molekularsiebe sind beschrieben in Ullmanns Encyklopädie der technischen Chemie, 4. Auflage, Band 17, ”Molekularsiebe”, Verlag Chemie Weinheim, New York, 1979, S. 9–18. Adsorptionsmittel sind beschrieben in Ullmanns Encyklopädie der technischen Chemie, 4. Auflage, Band 17, ”Adsorption”, S. 601–619, insbesondere S. 602–606.When Detergents suitable molecular sieves are described in Ullmanns Encyclopedia of Technical Chemistry, 4th Edition, Volume 17, "Molecular Sieves", Verlag Chemie Weinheim, New York, 1979, p. 9-18. Adsorbents are described in Ullmann's Encyclopaedia Technical Chemistry, 4th Edition, Volume 17, "Adsorption", pp. 601-619, especially pp. 602-606.
Bei einer Reinigungsvorrichtung gemäß der Erfindung wird das eingefüllte Gas ”in-line” in dem Druckbehälter, zum Beispiel einer Gasflasche, selbst einer Nachreinigung unterzogen, indem das Gas nur über ein mit dem Reinigungsmaterial zumindest teilweise gefülltes Steigrohr mittels der Armaturenanordnung aus dem Druckbehälter entnommen werden kann. Somit wird ein externer Reiniger entbehrlich.In a cleaning device according to the invention, the filled gas is "in-line" in the pressure vessel, for example a gas bottle, even subjected to a post-purification by the gas only via a with the cleaning material at least partially filled riser means of Armaturenan order can be removed from the pressure vessel. Thus, an external cleaner is unnecessary.
Bei Öffnen der Armaturenanordnung passiert das Gas zunächst das Reinigungsmaterial und danach das Sintermaterial, welches das Reinigungsmaterial in dem Steigrohr zurückhält. So kann bei Entnahme von Gas aus dem Druckbehälter kein vom Gas mitgerissenes Reinigungsmaterial austreten.When opening the Fittings arrangement, the gas passes first the cleaning material and then the sintered material containing the cleaning material in withholds the riser. So can when removing gas from the pressure vessel no gas entrained Emerge cleaning material.
Nach jeder Entleerung des Druckbehälters kann neues oder wiederaufbereitetes Reinigungsmaterial und gegebenenfalls auch Sintermaterial in den Druckbehälter eingefüllt werden, wodurch ein genaues Abstimmen der Kapazität an Reinigungsmaterial und damit eine gleichbleibend gute Reinigungswirkung erzielbar ist.To every emptying of the pressure vessel can new or recycled cleaning material and if necessary Also sintered material can be filled into the pressure vessel, creating an accurate Adjusting the capacity on cleaning material and thus a consistently good cleaning effect is achievable.
