Description

Die Erfindung betrifft eine dauerbrandsichere Flammensperre mit einem eine Leitung abschließenden Durchströmquerschnitt, in dem sich ein Flammensperreinsatz mit einer Flammensperranordnung befindet, die eine Vielzahl von die Dauerbrandsicherheit sicherstellenden Durchtrittsspalten aufweist, die durch einen gemeinsam mit einem glatten Metallstreifen gewickelten gewellten Metallstreifen gebildet sind.The invention relates to a flameproof flame arrestor having a flow-restricting cross-sectional area in which there is a flame arrester insert having a flame arrestor assembly having a plurality of passageway securing passageways ensuring continuous fire safety formed by a corrugated metal strip co-wound with a smooth metal strip.

Dauerbrandsichere Flammensperren dieser Art dienen der Entlüftung explosionsgefährdeter Anlagen. Sie müssen bei einer Entzündung der ausströmenden Gas- bzw. Produktdampf-Luft-Gemische dauerbrandsicher ausgelegt sein, also ein Abfackeln der Gemische über einen unbegrenzten Zeitraum ermöglichen, ohne dass es zu einem Flammendurchschlag in das zu schützende Anlagenteil kommen kann. Eine-dauerbrandsichere Flammensperre dieser Art ist beispielsweise durch DE 1 041 423 bekannt. Der Durchströmquerschnitt ist dabei ringförmig ausgebildet und umschließt ein hohles Kernstück, durch das Umgebungsluft strömt, die durch die Flamme beim Abfackeln des Gases oder Dampfs aus der Umgebung angesaugt wird und zur Kühlung eines als Flammensperre dienenden Ringrostes dient. Es hat sich herausgestellt, dass bei einer scheibenförmigen Flammensperre oder bei einer ringförmigen Flammensperre die freie Fläche der zum Durchtritt des Gases dienenden Flammensperre nicht zu groß sein darf, um eine unzulässige hohe Aufheizung im Zentrum der Flammensperre zu vermeiden, die zu einem Flammendurchschlag führen könnte. Daher können scheibenförmige Flammensperren nur bis zu einem bestimmten maximalen Durchmesser eingesetzt werden und dürfen ringförmige Flammensperren eine bestimmte Breite des Rings nicht überschreiten. Daher kommt es bei der Dimensionierung der Flammensperre in vielen Fällen zu Schwierigkeiten, da die Flammensperre jeweils der Anschlussweite der Leitung anzupassen ist und bei Gemischen mit großen Zünddurchschlagsvermögen (Explosionsgruppe IIB bzw. IIC), bei denen sehr enge flammenlöschende Spalte in der Flammensperre notwendig sind, die Breite bzw. der innere und/oder äußere Durchmesser der Flammensperre so zu dimensionierten ist, dass eine gewünschte Durchströmmenge erzielt wird.Durable flame arresters of this type are used to vent potentially explosive systems. They must be designed so that it can withstand fires in the event of ignition of the effluent gas or product / vapor / air mixtures, thus permitting flaring of the mixtures for an indefinite period of time, without it being possible for a flashover to occur in the part of the plant to be protected. A flame-retardant flame arrester of this kind is, for example, by DE 1 041 423 known. The flow cross-section is annular and encloses a hollow core piece, flows through the ambient air, which is sucked by the flame during flaring of the gas or vapor from the environment and used to cool a serving as a flame barrier ring grate. It has been found that in a disk-shaped flame arrestor or in an annular flame arrester, the free area of the flame arrester serving for the passage of the gas must not be too large to avoid unacceptable high heating in the center of the flame arrest, the Flame penetration could result. Therefore, disk-shaped flame arresters can only be used up to a certain maximum diameter and ring-shaped flame arresters must not exceed a certain width of the ring. Therefore, in many cases, the size of the flame arrester can be difficult because the flame arrestor has to be adapted to the connection of the pipe and for mixtures with high ignitability (explosion group IIB or IIC), where very narrow flame-extinguishing gaps in the flame arrester are necessary. the width or the inner and / or outer diameter of the flame arrester is dimensioned so that a desired flow rate is achieved.

US 5,336,083 offenbart eine Detonationssperranordnung, die mehrteilig aufgebaut ist. In Strömungsrichtung gesehen besteht sie aus einem flammenlöschenden Material, das eine Vielzahl von die Flammenlöschung bewirkenden Durchtrittsspalten aufweist. Dieses Material wird durch geeignete Schüttmaterialien gebildet. In Strömungsrichtung beiderseits des flammenlöschenden Materials befinden sich Detonationsbremsen in Form von aufeinander gestapelten Platten, die schlitzförmige Zwischenräume aufweisen, durch die die Flammenfront hindurchtreten muss, um zu dem flammenlöschenden Material in der Mitte zu gelangen. In einer Variante der Detonationsbremsen bestehen diese nicht aus geradlinigen Platten, sondern aus spirelförmig aufgewickelten Bändern, wobei die zum Gastritt benötigten schlitzförmigen Zwischenräume durch ein zwischengelegtes gewelltes Band als Abstandshalter sichergestellt werden. Die Detonantionsbremsen haben die Funktion, die Detonationsfront abzufangen und in Einzel-Detonationsfronten aufzuteilen. Die offenbarte Detonationssperranordnung ist nicht dauerbrandsicher sondern dazu ausgelegt, nur für eine zeitlich begrenzte Brandsicherheit zu sorgen. Diese Funktion übernimmt das mittig angeordnete Schüttmaterial mit den flammenlöschenden feinen Spalten, das über den gesamten Durchströmquerschnitt gleichmäßig verteilt ist. US 5,336,083 discloses a detonation arrestor assembly constructed in multiple parts. As seen in the flow direction, it consists of a flame-extinguishing material which has a multiplicity of passage gaps effecting flame extinction. This material is formed by suitable bulk materials. In the direction of flow on both sides of the flame-extinguishing material are detonation brakes in the form of stacked plates having slit-shaped spaces through which the flame front must pass in order to get to the flame-extinguishing material in the middle. In a variant of the detonation brakes they do not consist of rectilinear plates, but spirally wound bands, the slot-shaped intermediate spaces required for the gas passage are ensured by an interposed wavy band as a spacer. The detonation brakes have the function of intercepting the detonation front and dividing it into individual detonation fronts. The disclosed detonation detent order is not endurance-proof but is designed to provide only temporary fire safety. This function takes over the center arranged bulk material with the flame-extinguishing fine gaps, which is evenly distributed over the entire flow area.

FR 1 466 440 bzw. AT 250 544 offenbaren eine Flammensperre mit Durchtrittsspalten, die durch ein gemeinsames spiralförmiges Aufwickeln eines glatten Metallbandes mit einem mit herausgebogenen Zungen versehenen Metallband gebildet wird. Dadurch entsteht ein gleichmäßiger Aufbau der Flammensperre mit den Durchtrittsspalten. Der Bereich der Flammensperre mit den Durchtrittsspalten wird nach radial außen durch einen Ring begrenzt, der massiv ausgebildet sein kann oder dadurch gebildet wird, dass das glatte Metallband länger ist als das mit den herausgebogenen Zungen versehene Metallband, sodass am radial äußeren Ring der glatte Blechstreifen durch dicht aneinander anliegende Windungen ohne Durchtrittsspalte den Armierungsring 7 eines Sicherungskörpers bildet. Das Problem der Dauerbrandsicherheit und der Wärmeableitung ist dabei nicht angesprochen. FR 1 466 440 respectively. AT 250 544 disclose a flame arrester having passageways formed by co-winding helically a smooth metal strip with a metal strip provided with bent tabs. This results in a uniform structure of the flame arrester with the passage columns. The region of the flame arrester with the passage gaps is bounded radially outwardly by a ring which may be solid or is formed by the fact that the smooth metal strip is longer than the metal strip provided with the bent-out tongues, so that the smooth metal strip penetrates the radially outer ring tightly adjacent turns without passage column forms the reinforcing ring 7 of a fuse body. The problem of endurance safety and heat dissipation is not addressed.

Der Erfindung liegt die Aufgabe zugrunde, eine dauerbrandsichere Flammensperre in Form einer scheibenförmigen oder ringförmigen Flammensperre anzugeben, mit der eine die Dauerbrandsicherheit gefährdende Aufheizung der Flammensperre in einfacher Weise vermieden werden kann.The invention has for its object to provide a flameproof flame arrester in the form of a disc-shaped or annular flame arrester, with the endurance of a fire endangered heating of the flame arrester can be avoided in a simple manner.

Zur Lösung dieser Aufgabe ist erfindungsgemäß eine dauerbrandsichere Flammensperre der eingangs erwähnten Art dadurch gekennzeichnet, dass innerhalb des Durchströmquerschnitts wenigstens zwei Flammensperranordnungen mit den Durchtrittsspalten angeordnet sind, zwischen denen sich ein einen Kühlring bildender konzentrischer Abschnitt befindet, der massiv ohne Durchtrittsspalte ausgebildet ist.To achieve this object, a flameproof barrier of the type mentioned above is inventively characterized in that within the Durchströmquerschnitts at least two Flammensperranordnungen are arranged with the passage gaps, between which there is a cooling ring forming a concentric section, which is solid without passage gaps.

Der konzentrische Abschnitt kann als ringförmiger Abschnitt ausgebildet sein und somit den Durchströmquerschnitt in mehrere ringförmige Durchströmflächen unterteilen. Ergänzend dazu kann ein zentrisch angeordneter Kern vorgesehen sein.The concentric portion may be formed as an annular portion and thus the flow area in a plurality of annular Divide flow areas. In addition to this, a centrally arranged core can be provided.

Zweckmäßigerweise ist die mit den Durchtrittsspalten ausgebildete Querschnittsfläche des Flammensperreinsatzes größer als die Querschnittsfläche ohne Durchtrittsspalte. In einer bevorzugten Ausführungsform der Erfindung beträgt die Fläche ohne Durchtrittsspalte zwischen 35 und 40 % der Gesamtfläche einer Ringflammensperre und zwischen 25 und 35 % der Querschnittsfläche einer Scheiben-Flammensperre.Conveniently, the cross-sectional area of the flame arrester insert formed with the passage gaps is larger than the cross-sectional area without passage gaps. In a preferred embodiment of the invention, the area without through-gaps is between 35 and 40% of the total area of a ring flame arrester and between 25 and 35% of the cross-sectional area of a disc flame arrester.

Der erfindungsgemäß vorgesehene wenigstens eine konzentrische Abschnitt unterteilt somit die Fläche der scheibenförmigen Flammensperre, wodurch eine unzulässige Aufheizung im radialen Innenbereich der Flammensperre vermieden wird. Hierzu kann der wenigstens eine konzentrische Abschnitt aus einem wärmeisolierenden Material gebildet sein, um den Bereich, in dem sich eine Flamme auf der Fläche der Flammensperre ausbildet, zu begrenzen und eine Aufheizung in diesem Bereich zu verringern. Es ist aber auch möglich und in vielen Fällen bevorzugt, den konzentrischen Abschnitt aus einem gut Wärme leitenden Material auszubilden, um im konzentrischen Bereich eine verbesserte Wärmeabfuhr innerhalb des Durchströmquerschnitts der Flammensperre zu bewerkstelligen. So kann beispielsweise ein zentrisch angeordneter Kern als konzentrischer Abschnitt, der aus gut Wärme leitenden Material gebildet ist, eine verbesserte Wärmeableitung im Zentrum des Durchströmquerschnits bewirken und beispielsweise eine scheibenförmige Flammensperre zu einer Flammensperre werden lassen, deren Durchtrittsspalte auf einer ringförmigen Fläche angeordnet sind.The inventively provided at least one concentric section thus divides the surface of the disk-shaped flame arrester, whereby an inadmissible heating in the radially inner region of the flame arrestor is avoided. For this purpose, the at least one concentric portion may be formed of a heat-insulating material to limit the area in which forms a flame on the surface of the flame arrester, and to reduce heating in this area. But it is also possible and in many cases preferred to form the concentric portion of a good heat conductive material to accomplish in the concentric region improved heat dissipation within the flow area of the flame arrester. Thus, for example, a centrally arranged core as a concentric section, which is formed of good heat conducting material, cause improved heat dissipation in the center of Durchströmquerschnits and let, for example, a disc-shaped flame arrest to a flame arrester, whose passage gaps are arranged on an annular surface.

In einer besonders bevorzugten Ausführungsform der Erfindung kann der konzentrische Abschnitt aus einem spiralförmig dicht an dicht gewickelten glatten Metallstreifen gebildet sein. Dies ist besonders vorteilhaft, wenn die Durchtrittsspalte des Durchströmquerschnitts in an sich bekannter Weise durch einen gemeinsam mit einem glatten Metallstreifen spiralförmig gewickelten gewellten Metallstreifen gebildet sind. Unter Beibehaltung des Wickelvorganges kann zur Bildung eines erfindungsgemäßen konzentrischen Abschnittes die Zufuhr des gewellten Metallstreifens zu der Wickelvorrichtung gestoppt und nur noch der glatte Metallstreifen gewickelt werden, bis regelmäßig nach einer gewissen Dicke des so entstandenen konzentrischen Abschnitts der gewellte Metallstreifen wieder mit dem glatten Metallstreifen zugeführt wird, um einen äußeren ringförmigen Abschnitt um den konzentrischen Abschnitt herum zu bilden.In a particularly preferred embodiment of the invention, the concentric portion may be formed from a smoothly wound tightly wound smooth metal strip. This is particularly advantageous if the passage gaps of the flow cross-section are formed in a manner known per se by a corrugated metal strip spirally wound together with a smooth metal strip. While maintaining the winding operation, the supply of the corrugated metal strip to the winding device can be stopped to form a concentric section according to the invention and only the smooth metal strip are wound until regularly after a certain thickness of the resulting concentric section of the corrugated metal strip is fed back to the smooth metal strip , around to form an outer annular portion around the concentric portion.

Figur 1 zeigt ein erstes Ausführungsbeispiel einer erfindungsgemäßen Flammensperre, die ringförmig ausgebildet ist. Demgemäß ist ein Gehäuse 1 vorgesehen, das einen ringförmigen Umfassungskäfig für einen ringförmigen Durchströmquerschnitt 2 bildet. Ein Mittelteil 3 wird durch das Gehäuse 1 frei gelassen. FIG. 1 shows a first embodiment of a flame arrester according to the invention, which is annular. Accordingly, a housing 1 is provided which has an annular cage for cage forms an annular flow area 2. A middle part 3 is left free by the housing 1.

In den Durchströmquerschnitt 2 sind zwei ringförmige Flammensperranordnungen 4 angeordnet, die radial durch einen konzentrischen Abschnitt 5 voneinander getrennt sind. Die Flammensperranordnungen 4 weisen Durchtrittsspalte auf, während der konzentrische Abschnitt 5 ohne Durchtrittsspalte ausgebildet ist und aus einem gut Wärme leitenden Material, insbesondere Metall, besteht.In the flow cross-section 2, two annular flame barrier arrangements 4 are arranged, which are radially separated from each other by a concentric section 5. The flame arrestor assemblies 4 have passage gaps, while the concentric portion 5 is formed without passage gaps and consists of a good heat-conducting material, in particular metal.

Die Flammensperranordnungen 4 bilden zusammen mit dem konzentrischen Abschnitt 5 einen Flammensperreinsatz 4, 5 mit einer Breite B. Die radiale Breite B2 des einen Kühlring bildenden konzentrischen Abschnitts 5 ist etwa gleich groß wie die gleich groß ausgebildeten Breiten B1 der Flammensperranordnungen 4.The flame barrier arrangements 4 together with the concentric section 5 form a flame barrier insert 4, 5 with a width B. The radial width B2 of the concentric section 5 forming a cooling ring is approximately the same as the equal widths B1 of the flame barrier arrangements 4.

Figur 2 zeigt eine Armatur 6, die mit der Flammensperre gemäß Figur 1 ausgestattet ist. Die Armatur 6 weist einen Anschlussflansch 7 für eine von einem Behälter kommende Leitung oder einen entsprechenden Anschlussflansch eines Behälters auf. Aus dem Behälter ausströmendes Gas (worunter auch Produktdämpfe verstanden werden) strömt in Richtung der in Figur 2 dargestellten Strömungspfeile 8. Die Armatur 6 weist ein sich trichterförmig erweiterndes Gehäuse 9 auf, das von dem Gehäuse 1 der Flammensperre abgeschlossen wird. Das Gas durchströmt die Flammensperrabschnitte 4 und kann nach dem Durchtritt durch die Flammensperre durch Entzündung zu einer Flamme 10 verbrannt und damit unschädlich gemacht werden. Der ringförmige konzentrische Abschnitt 5 bewirkt eine Begrenzung der ringförmigen Flächen der Flammensperrabschnitte 4 und bewirkt aufgrund seiner massiven Ausbildung ohne Durchtrittsspalte eine gute Wärmeableitung, also eine Kühlung der Flammensperrabschnitte 4. Dadurch wird verhindert, dass die Flammensperrabschnitte 4 sich auf der zum Gehäuse 9 der Armatur 6 zeigenden Seite soweit aufheizen, dass die Entzündungstemperatur für das ausströmende Gas erreicht wird. FIG. 2 shows a fitting 6, with the flame arrester according to FIG. 1 Is provided. The fitting 6 has a connection flange 7 for a line coming from a container or a corresponding connection flange of a container. Gas flowing out of the container (which also means product vapors) flows in the direction of the in FIG. 2 shown flow arrows 8. The fitting 6 has a funnel-shaped widening housing 9, which is completed by the housing 1 of the flame arrester. The gas flows through the flame barrier sections 4 and, after passing through the flame barrier, can be burned by ignition into a flame 10 and thus made harmless. The annular concentric portion 5 causes a limitation of the annular surfaces of the flame trap sections 4 and causes due to its massive formation without passage gaps a good heat dissipation, so a Cooling the flame barrier sections 4. This prevents the flame barrier sections 4 from heating up on the side facing the housing 9 of the fitting 6 until the ignition temperature for the outflowing gas is reached.

Bei der in Figur 3 dargestellten zweiten Ausführungsform sind konzentrisch zueinander drei Flammensperrabschnitte 4 angeordnet, die durch zwei konzentrische Abschnitte 5 in Ringform radial voneinander getrennt sind. Auf diese Weise lässt sich eine Flammensperre mit einem größeren Durchströmquerschnitt realisieren, ohne die Gefahr einer zu großen Aufheizung der Flammensperrabschnitte 4 eingehen zu müssen.At the in FIG. 3 shown second embodiment concentric with each other three flame trap sections 4 are arranged, which are separated by two concentric sections 5 in ring form radially from each other. In this way, a flame arrester can be realized with a larger flow area without the risk of excessive heating of the flame trap sections 4 must be received.

Die in den Figuren 1 bis 3 dargestellten konzentrischen Abschnitte 5 können aus massiven Metall gebildet sein, um eine gute Wärmeableitung zu bewirken. Dabei muss jedoch sichergestellt werden, dass am Übergang zwischen den Flammensperrabschnitten 4 und den konzentrischen Abschnitten 5 keine zu großen Spaltweiten entstehen.The in the FIGS. 1 to 3 shown concentric portions 5 may be formed of solid metal, to effect a good heat dissipation. However, it must be ensured that at the transition between the flame trap sections 4 and the concentric sections 5 no too large gap widths arise.

Eine Vereinfachung der Fertigung lässt sich gemäß den Figur 4 angedeuteten Ausführungsbeispiel dadurch erzielen, dass die Flammensperrabschnitte 4 - wie an sich bekannt - durch ein gemeinsames spiralförmiges Aufwickeln von jeweils einem gewellten und einem glatten Metallband gebildet wird. Der konzentrische Abschnitt 5 kann in einfacher Weise durch Weiterwickeln des glatten Metallbandes erfolgen, das somit dicht an dicht ohne Durchtrittsspalte gewickelt einen quasi massive konzentrischen Abschnitt 5 in Form eines Kühlringes ausbildet.A simplification of the production can be according to FIG. 4 indicated embodiment achieved in that the flame barrier sections 4 - as is known per se - is formed by a common spiral winding of a respective corrugated and a smooth metal strip. The concentric section 5 can be carried out in a simple manner by further winding the smooth metal strip, which thus wound tightly sealed without passage gaps forms a quasi-massive concentric section 5 in the form of a cooling ring.

Bei dem in Figur 5 dargestellten Ausführungsbeispiel bildet das Gehäuse 1' einen Umfassungskäfig für eine scheibenförmige Flammensperre, wie sie für kleinere Geräteabmessungen verwendbar sind. Ähnlich wie in der Ausführungsform gemäß Figur 1 werden zwei ringförmige Flammensperrabschnitte 4 durch einen konzentrischen Abschnitt 5 in Form eines Ringes radial voneinander getrennt. Zusätzlich ist jedoch ein weiterer konzentrischer Abschnitt 11 in Form eines zentrischen Kerns vorgesehen, um den herum der radial innere Flammensperrabschnitt ringförmig ausgebildet ist.At the in FIG. 5 illustrated embodiment, the housing 1 'forms a containment cage for a disk-shaped flame arrester, such as they are suitable for smaller device dimensions. Similar to the embodiment according to FIG FIG. 1 two annular flame trap sections 4 are radially separated from each other by a concentric section 5 in the form of a ring. In addition, however, another concentric portion 11 is provided in the form of a central core, around which the radially inner flame trap is annular.

Die insbesondere zum Querschnittszentrum hin kritische Aufheizung einer scheibenförmigen Flammensperre wird somit einerseits durch den ringförmigen konzentrischen Abschnitt 5 ("Kühlring") und andererseits durch den im Zentrum angeordneten konzentrischen Abschnitt 11 ("Kühlkern") verhindert.The heating of a disk-shaped flame arrester, which is particularly critical for the cross-sectional center, is thus prevented on the one hand by the annular concentric section 5 ("cooling ring") and on the other hand by the concentric section 11 ("cooling core") arranged in the center.

Figur 6 zeigt ein Ausführungsbeispiel einer spiralförmigen Wicklung einer Flammensperre, die aus einer gemeinsamen Aufwicklung eines gewellten Metallbandes 41 mit einem glatten Metallband 42 gebildet ist. Innerhalb der kreisförmigen Fläche des Durchströmquerschnitts 2 sind mehrere, hier fünf ringförmige konzentrische Abschnitte 5 ausgebildet, die dadurch hergestellt sind, dass in den Bereichen der konzentrischen Abschnitte 5 das glatte Metallband 42 allein, d.h. ohne dass gewellte Metallband 41, aufgewickelt worden ist. FIG. 6 shows an embodiment of a spiral winding of a flame arrester, which is formed from a common winding of a corrugated metal strip 41 with a smooth metal strip 42. Within the circular surface of the flow cross-section 2 a plurality, here five annular concentric portions 5 are formed, which are produced in that in the areas of the concentric portions 5, the smooth metal strip 42 alone, that is, without corrugated metal strip 41, has been wound.

Im Zentrum des Durchströmquerschnitts 2 befindet sich ein konzentrischer Abschnitt 11 in Form eines zentrischen Kerns, der vorzugsweise ein massiver Einsatz aus einem gut Wärme leitenden Material ist. Somit bilden sich im Durchströmquerschnitt benachbart zu den konzentrischen ringförmigen Abschnitten 5 jeweils Flammensperrabschnitte 4 mit Durchströmspalten aus, deren Flächen begrenzt sind, sodass eine zu große Aufheizung der Flammensperrabschnitte 4 sicher vermieden werden kann.In the center of the flow cross-section 2 is a concentric portion 11 in the form of a central core, which is preferably a solid insert of a good heat conductive material. Thus, in the flow cross-section adjacent to the concentric annular sections 5 each flame barrier sections 4 form with Durchströmspalten whose surfaces are limited, so that an excessive heating of the flame barrier sections 4 can be safely avoided.
