Description

Die Erfindung betrifft eine weitere Ausbildung der Vorrichtung zur Sicherung feuergefährlicher Flüssigkeiten und Gase gegen anlaufende @Explosionen nach Patent 754 I10.The invention relates to a further embodiment of the device for Protection of flammable liquids and gases against starting @explosions according to patent 754 I10.

Während bei der Vorrichtung nach dem Patent 7541.1o der Zutritt .des feuergefährlichen Stoffes in das Gehäuse und zum Flammenfilter in der Anlaufleitung, also vor dem Rückführungskanal angeordnet ist, ist der Zutritt in das Gehäuse und zum Flammenfilter bei der Erfindung im _ rücklaufenden Teil des Rückführungskanals angeordnet.While in the device according to patent 7541.1o the access .des flammable substance in the housing and to the flame filter in the start-up line, is thus arranged in front of the return channel, access is in the housing and to the flame filter in the invention in the return part of the return duct arranged.

Die anlaufende Explosion muß also vor Passieren des Zutritts c einen wesentlichen Teil des Rückführungskanals a durcheilen. Durch den Widerstand der in Abhängigkeit von der NW bestimmten Krümmung des Rückführungskanals wird die Geschwindigkeit herabgemindert, wodurch gleichzeitig die Randdrücke der Flammenfront geringer werden. Die Gefahr der seitlichen Fortpflanzung der anlaufenden Explosionen mit erhöhter Anfangsgeschwindigkeit wurde dadurch beseitigt, so daß die den Einströrnun@gskanal umfassende kammerartige Erweiterung nach dem Hauptpatent in Fortfall kommen konnte. Hierdurch wurde eine Herabsetzung des Durchflußwiderstandes während des normalen Betriebes erreicht. Gleichzeitig wird der durch die anlaufende Explosion in dem Gehäuse d entstehende Vordruck durch die Herabminderung der Geschwindigkeit naturgemäß auch geringer, wodurch die Durchzündfähigkeit des explosiven Gemisches kleiner, also die Durchschlagssicherung gegenüber der Vorrichtung nach dem Patent 754 11o eine noch größere ist. Eingehende Versuche haben ergeben, daB die in dem Patent 754 110 vorgesehene kammerartige Erweiterung der Zuleitung gleichfalls in Fortfall kommen konnte, da die Geschwindigkeit der seitlichen -Ausbreitung der Flammenfront weitaus geringer ist als die Geschwindigkeit in der Stoßrichtung.The starting explosion must therefore rush through a substantial part of the return channel a before it passes through the inlet c. The resistance of the curvature of the return duct, which is determined as a function of the NW, reduces the speed, which at the same time reduces the edge pressures of the flame front. The danger of lateral propagation of the starting explosions at an increased initial speed was thereby eliminated, so that the chamber-like expansion that encompasses the inflow canal according to the main patent can no longer be used. This reduced the flow resistance during normal operation. At the same time, the pre-pressure created by the explosion in the housing d is naturally also lower due to the reduction in speed, which means that the ignitability of the explosive mixture is lower, i.e. the breakdown protection is even greater compared to the device according to patent 754 11o. Extensive tests have shown that the chamber-like expansion of the supply line provided in patent 754 1 10 could also be omitted, since the speed of the lateral propagation of the flame front is much slower than the speed in the direction of impact.

Die Druckwelle durcheilt also so schnell den Ringkanal, daß eine Gegenströmung im rücklaufenden Teil nicht eintreten kann.The pressure wave rushes through the ring canal so fast that a countercurrent cannot occur in the returning part.

Abb. I zeigt die schematische Darstellung einer solchen Vorrichtung mit einem im rücklaufenden Teil des Ringkanals angeordneten Flammenfilter in Winkelanschluß, Abb. II eine solche mit einem am rücklaufenden Teil des Ringkanals angeordneten Flammenfilter in waagerechtem Anschluß.Fig. I shows the schematic representation of such a device with a flame filter arranged in the return part of the ring duct in an angle connection, Fig. II one with one arranged on the returning part of the ring channel Flame filter in horizontal connection.
