Description

Die Erfindung betrifft eine Einrichtung zur Verhinderung des Schmutzansatzes an den scharfen Kanten von Stauscheiben, die in Gasleitungen eingebaut sind, um die durch die Leitung strömende Gasmenge zu messen. The invention relates to a device for preventing the build-up of dirt on the sharp edges of baffle plates installed in gas pipes measure the amount of gas flowing through the pipe.

Für die Feststellung der durch eine Leitung strömenden Gasmenge ist es bekannt, in die Gasleitung eine Stauscheibe einzubauen, durch die ein Druckunterschied vor und hinter dieser Stauscheibe hervorgerufen wird. Durch die Feststellung der Höhe dieses. Druckunterschiedes kann. dadurch geeignete Meßinstrumente in an sich bekannter Weise die durch die Leitung strömende Gasmenge festgestellt werden. To determine the amount of gas flowing through a pipe is it is known to build a baffle plate in the gas line through which a pressure difference is caused in front of and behind this baffle plate. By finding the Height of this. Pressure difference can. thereby suitable measuring instruments in itself In a known manner, the amount of gas flowing through the line can be determined.

Es hat sich nun bei derartigen Stauscheiben gezeigt, daß sich an den scharfen Düsenkanten der Stauscheibe der im Gas enthaltende Schmutz in Form von NaphtShalin, Gichtstaub oder ähnlichen Ablagerungen festsetzt und dadurch die für eine einwandfreie Messung der durch die Leitung strömenden Gasmenge notwendigen scharfen Kanten abrundet, was sich für eie einwandfreie Feststellung des Druckunterschiedes vor und hinter der Stauscheibe ungünstig auswirkt. It has now been shown with such baffle plates that the sharp nozzle edges of the baffle plate to shape the dirt in the gas of naphthoshalin, gout dust or similar deposits and thereby the necessary for a correct measurement of the amount of gas flowing through the pipe rounds sharp edges, which is good for a proper determination of the pressure difference has an unfavorable effect in front of and behind the baffle plate.

Um nun das Abrunden der Kanten der Stauscheibe durch den sich ansetzenden Schmutzniederschlag zu vermeiden, schlägt die Erfindung vor, die Kanten einer ständigen selbsttätigen Reinigung zu unterwerfen, und zwar mittels einer in die Stauscheibe eingefüllten, vom dem durchströmenden Gas in ihrer Wirkung unbeeinflußten Reinigungsflüssigkeit, welche durch einen engen Schlitz im Düsenbereich der Stauscheibe allmählich austritt und die Düsenkanten gegen das Ansetzen von. Schmutz schützt. Der in der Leitung vorhandene Gasstrom saugt die Flüssigkeit aus dem engen Schlitz über die scharfen Düsenkanten hinweg an, und die Flüssigkeit übt hierbei ihre Reinigungswirkung aus. To round off the edges of the baffle plate by the attaching To avoid the accumulation of dirt, the invention proposes the edges of a permanent to submit to automatic cleaning, namely by means of one in the baffle plate Filled cleaning liquid, the effect of which is unaffected by the gas flowing through, which gradually emerges through a narrow slot in the nozzle area of the baffle plate and the nozzle edges against the attachment of. Dirt protects. The one on the line existing gas flow sucks the liquid from the narrow slot over the sharp And the liquid exerts its cleaning effect.

In der Zeichnung ist der Vorschlag gemäß der Erfindung in einem Ausführungsbeispiel schematisch veranschaulicht, und zwar im Vertikalschnitt durch die Stauscheibe. In the drawing, the proposal according to the invention is in one embodiment illustrated schematically, namely in vertical section through the baffle plate.

Die Stauscheibe ist mit I bezeichnet, und 2 sind deren scharfe Kanten. Mit 3 ist ein innerhalb der Stauscheibe I durch Ausdrehung geschaffener Ringraum für die Aufnahme der Reinigungsflüssigkeit bezeichnet, der durch eine Abdeckscheibe 4 zum geschlossenen Flüssigkeitsraum gestaltet wird und der nur durch einen engen Spalt 5 im Düsenbereich mit dem Leitungsinnern in Verbindung steht, über den die Reinigungsflüssigkeit über die scharfen Düsenkanten hingweg durch die Saugwirkung des durch die Leitung strömenden Gases aus dem Flüssigkeitsraum 3 ständig angesaugt wird und dabei ihre reinigende Wirkung auf die Düsenkanten ausübt. Mit 6 ist eine durch Gewindestopfen 7 verschließbare Füllöffnung für das Einfüllen der Reinigungsflüssigkeit in den Ringraum 3: bezeichnet. The baffle plate is labeled I, and 2 are its sharp edges. With 3 is an annular space created within the baffle plate I by turning for the absorption of the cleaning fluid designated by a cover plate 4 is designed to be a closed liquid space and only through a narrow Gap 5 in the nozzle area is connected to the inside of the line, via which the Cleaning fluid hung over the sharp nozzle edges due to the suction effect of the gas flowing through the line from the liquid space 3 is constantly sucked in and thereby exerts its cleaning effect on the nozzle edges. At 6 there is one Filling opening, which can be closed by threaded stoppers 7, for filling in the cleaning liquid in the annulus 3: designated.
