Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf eine Filteranordnung an Leitungsmündungen bei Gasanalysiervorrichtungen und kennzeichnet sich dadurch, daß der Filter aus einem offenen, zweckmäßigerweise trichterförmigen Gefäß besteht, das mit geeignetem Filterstoff gefüllt ist und in das das Ende des Gasäuslaßrohres eintaucht.The invention relates to a filter arrangement at line openings in gas analyzing devices and is characterized in that the filter consists of an open, expediently funnel-shaped vessel, which is filled with suitable filter material and into which the end of the gas outlet tube immersed.

Hierdurch wird die Einrichtung billiger, leichter auswechselbar und wirksamer als die bisherigen.This makes the device cheaper, easier to replace and more effective than that previous.

Zwei Ausführungsformen der Erfindung sind auf der Zeichnung veranschaulicht, in Fig. 1 bei einem wagerechten, und in Fig. 2 bei einem senkrechten Gaskanal.Two embodiments of the invention are illustrated in the drawing, in FIG. 1 with a horizontal gas duct and in FIG. 2 with a vertical gas duct.

In einen Gaskanal a, z. B. den Rauchgaskanal eines Dampfkessels, tritt das an die Gasanalysiervorrichtung angeschlossene Rohr b ein, das gemäß der Erfindung mit seinem im Gaskanal ausmündenden Ende in ein offenes, zweckmäßigerweise trichterförmiges Gefäß c, das mit geeignetem Filterstoff d, z. B. Sand, gefüllt ist, eintaucht.In a gas channel a, z. B. the flue gas duct of a steam boiler, the pipe b connected to the gas analyzer occurs, which according to the invention with its end opening into the gas duct in an open, suitably funnel-shaped vessel c, which is filled with a suitable filter material d, e.g. B. sand, is filled, immersed.

Das Rohr δ, das zweckmäßigerweise aus Kupfer besteht, ist von einem Schutzmantel e, der mit einem Boden f versehen ist, umgeben, worin das Gefäß c mittels Arme g μηα einer Rohrhülse h befestigt ist.The tube δ, which is expediently made of copper, is surrounded by a protective jacket e, which is provided with a base f , in which the vessel c is attached to a tube sleeve h by means of arms g μηα.

Auf diese Weise wird eine bereits im Gaskanal filtrierte Probe, ohne Benutzung eines äußeren Filters, durch das zur Gasanalysiervorrichtung führende Rohr δ entnommen.In this way, a sample that has already been filtered in the gas channel becomes available without using one outer filter, taken through the tube δ leading to the gas analyzer.

Die Ausführungsform nach Fig. 2 unterscheidet sich von der nach Fig. 1 nur dadurch, daß das Rohr b und die Hülse β wagerecht liegen. Das Ende des Rohres h ist daher winkelig abwärts gebogen. -The embodiment of FIG. 2 differs from that of FIG. 1 only in that the tube b and the sleeve β are horizontal. The end of the tube h is therefore bent downwards at an angle. -

Der Kanal α kann auch eine Abzweigung eines Rauchkanals, z. B. eine Kreisleitung, durch die ein fortgesetzter Umlauf des Gases stattfindet, bilden.The channel α can also be a branch of a smoke channel, for. B. form a loop through which the gas continues to circulate.
