Entnahmevorrichtung für Druckgase zur Gasanalyse Extraction device for compressed gases for gas analysis

809884/0311809884/0311

Die Erfindung betrifft eine Entnahmevorrichtung für Druckgase zur Gasanalyse entsprechend dem Gattungsbegriff des Patentanspruches.The invention relates to an extraction device for compressed gases for gas analysis according to the generic term of the claim.

Nach DlN 51853 ist es Zweck der Probenahme, Proben zu erhalten, die dem Durchschnitt des betreffenden Gases oder dem Durchschnitt eines bestimmten Anteils des betreffenden Gases genau entsprechen und es ermöglichen, Kenndaten der Gesamtmenge oder eines bestimmten Anteils des Gases genau zu ermitteln. Voraussetzung dazu ist eine Entnahmevorrichtung, in der sich die Zusammensetzung der Probe nicht verändert.According to DlN 51853 the purpose of sampling is to receive samples which is the average of the gas in question or the average of a certain proportion of the gas in question Gases correspond exactly and allow characteristic data of the total amount or a certain proportion of the gas to be determined exactly. The prerequisite for this is a removal device in which the composition is of the sample is not changed.

Die Durchführung der Gasanalyse erfolgt nach Druckminderuna in der bei Hochdruck entnommenen Gasprobe. Für die Entnahme einer Probe aus Hochdruckgas wird ein Druckminderer zwischen Hochdruckleitung und Probenahmehahn eingeschaltet, damit sich keine Gasbeimengungen, wie Feuchtigkeit und Naphthalin, vor dem Probenahmehahn abscheiden. Als Druckminderer kann ein Nadelventil oder ein Realer verwendet werden. Es hat sich gezeigt, daß für einige Zeit in normaler Umgebungsluft gelagerte Entnahmevorrichtungen, die im wesentlichen den Druckminderer enthalten, an ihren inneren Oberflächen durch Adsorption Feuchtigkeit aufgenommen haben. Das zusätzliche Wasser verdampft dann bei der Probenahme wieder und verfälscht damit, die Meßergebnisse. (DIN 51853, Februar 19€0)The gas analysis is carried out after pressure reduction in the gas sample taken at high pressure. To take a sample from high-pressure gas, a pressure reducer is installed between the high-pressure line and the sampling tap switched on so that there are no gas admixtures, such as Separate moisture and naphthalene in front of the sampling valve. A needle valve or a real can be used. It has been shown that extraction devices stored in normal ambient air for some time, which essentially contain the pressure reducer, on their inner surfaces by adsorption Have absorbed moisture. The additional water then evaporates again during sampling and falsifies it thus, the measurement results. (DIN 51853, February 19 € 0)

Aufgabe der Erfindung ist die Verhinderung von Meßfehlern bei der Gasanalyse, ausgelöst durch in der Entnahmevorrichtung anhaftendes Wasser.The object of the invention is to prevent measurement errors in gas analysis triggered by in the sampling device adherent water.

Die Lösung der Aufgabe erfolgt gemäß dem Kennzeichen des Anspruches.The problem is solved according to the characteristics of the claim.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß auf jeden Fall das Eindringen von Fremdgasen oder Feuchtigkeit in die Entnahmevorrichtung verhindert wird. Die Rückschlagventile öffnen sich nur bei der direkten Benutzung, also bei der Entnahme des zu analysierenden Gases aus dem Druckbehälter oder dem unter Druck stehenden Leitungsnetz. Die Aufbewahrung und auch der Transport der Entnahmevorrichtung verlangt nicht die Einhaltung von besonderen Bedingungen, um die Genauigkeit der nächsten Gasanalyse sicherzustellen. Die nach der Erfindung gefundene Lösung ist einfach im Aufbau und sicher in der Benutzung.The advantages achieved by the invention are in particular that in any case the penetration of Foreign gases or moisture in the extraction device is prevented. The check valves only open in direct use, i.e. when the gas to be analyzed is removed from the pressure vessel or the under Line network under pressure. The storage and also the transport of the removal device does not require Compliance with special conditions to ensure the accuracy of the next gas analysis. According to the invention The solution found is simple in structure and safe to use.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden beschrieben.An embodiment of the invention is shown in the drawing and is described below.

Die Probenahme unter Hochdruck erfolgt aus dem Hochdruckbehälter oder der Leitung 1. Die Entnahmevorrichtung 2 ist über die Kupplung 3 an den Hochdruckbehälter oder die Leitung 1 angeschlossen.The sampling under high pressure takes place from the high pressure container or the line 1. The extraction device 2 is via the coupling 3 to the high-pressure tank or the line 1 connected.

Die Entnahmevorrichtung 2 besteht aus dem nach DIN 51853 geforderten Druckminderer 4, in Strömungsrichtung eingeschaltet vor dem Probenahmehahn 5. Zur Mengenmessung der entommenen Gasprobe ist dem Probenahmehahn 5 ein bekannter Durchflußmengenmesser 6 nachgeschaltet. Die Rohrleitung 7 verbindet die Elemente. Sie besitzt an der Zuströmseite die Kupplung 3 und an dem Abströmende den Analysenanschluß 8 für das anzuschließende GasanalysengerMt, im vorliegenden Beispiel ein bekanntes Gasspürröhrchen 9.The extraction device 2 consists of the pressure reducer 4 required by DIN 51853, switched on in the direction of flow in front of the sampling cock 5. The sampling cock 5 is a known one for measuring the quantity of the gas sample taken Flow meter 6 connected downstream. The pipeline 7 connects the elements. It has the coupling 3 on the inflow side and the analysis connection on the outflow end 8 for the gas analyzer to be connected, in the present example a known gas detection tube 9.

Direkt hinter der Kupplung 3 und vor dem Analysenanschluß sind in die Rohrleitung 7 die Rückschlagventile 10 und 11The check valves 10 and 11 are in the pipeline 7 directly behind the coupling 3 and in front of the analysis connection

eingebaut. Sie verschließen im drucklosen Zustand die Rohrleitung 7 und damit die Entnahmevorrichtung 2 gegenüber der Außenatmosphare und verhindern damit das Eindringen von Fremdgasen oder Feuchtigkeit, mit denen die Ergebnisse der nächsten Messung verfälscht werden könnten.built-in. They close the in the depressurized state Pipeline 7 and thus the extraction device 2 against the outside atmosphere and thus prevent this Penetration of foreign gases or moisture with which the results of the next measurement could be falsified.
