Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur flammenlosen Druckentlastung mit wenigstens einer inneren Lage aus einem textilen Flächengebilde oder einem textilen Körpergebilde aus Metallfäden.The present invention relates to a device for flameless pressure relief with at least one inner layer of a textile fabric or a textile body of metal filaments.
Aus dem Stand der Technik sind verschiedene Vorrichtungen zur flammenlosen Druckentlastung bekannt. So stellt die Rembe GmbH Safety + Control in 59929 Brilon unter dem Namen Q-Rohr oder Q-Box verschiedene Vorrichtungen zur flammenlosen Druckentlastung her und vertreibt diese.Various devices for flameless pressure relief are known from the prior art. For example, Rembe GmbH Safety + Control in 59929 Brilon produces and sells various devices for flameless pressure relief under the name Q-Rohr or Q-Box.
Auch in der Patentliteratur werden Vorrichtungen zur flammenlosen Druckentlastung beschrieben, zum Beispiel in der Druckschrift
Bei der flammenlosen Druckentlastung werden über die dafür vorgesehenen Vorrichtungen die in einem Gebäude oder einem Gefäß entstehenden Flammen in den Lagen aus den textilen Flächengebilden aus Metallfäden extrem effizient abgekühlt und so erstickt. Auch ein in dem Gebäude oder dem Gefäß herrschender Überdruck wird über die Vorrichtung abgebaut. Die Flammen treten nicht aus der Vorrichtung aus.In the flameless pressure relief, the resulting in a building or a vessel flames are extremely efficiently cooled in the layers of textile fabrics of metal filaments and so stifled. Also, a pressure prevailing in the building or the vessel overpressure is reduced by the device. The flames do not escape from the device.
Die Konstruktion der bekannten Vorrichtungen zur flammenlosen Druckentlastung ist aufwändig. Sowohl die Q-Box als auch das Q-Rohr definieren einen Raum, in den die Flammen eintreten können und der von der wenigstens einen inneren Lage begrenzt wird. Durch die Wahl der Größe des Raums wird die Fläche vorgegeben, über die die Druckentlastung stattfinden kann. Sowohl die Q-Box als auch das Q-Rohr weisen einen Außenkorb oder ein Außengehäuse auf, der oder das die inneren Lagen aus textilen Flächengebilden aus Metallfäden zusammenhält. Zur flammenlosen Druckentlastung trägt der Außenkorb bzw. das Außengehäuse nicht bei. Streben des Außenkorbs bzw. des Außengehäuses verringern sogar die für die Druckentlastung wirksame Fläche.The construction of the known devices for flameless pressure relief is complex. Both the Q-box and the Q-tube define a space into which the flames may enter and which is bounded by the at least one inner layer. By choosing the size of the room, the area over which the pressure relief can take place is specified. Both the Q-box and the Q-tube have an outer basket or housing which holds the inner layers of metallic filament fabrics together. For flameless pressure relief, the outer basket or the outer housing does not contribute. Pursuit of Outdoor basket or the outer housing reduce even effective for the pressure relief surface.
Eine weitere Eigenschaft der bisherigen Konstruktionen ist, dass durch den Außenkorb bzw. das Außengehäuse die Form der Vorrichtung und auch der Eintrittsöffnung fest vorgegeben ist. Eine Anpassung der Vorrichtung auf verschiedene Raumverhältnisse am Einsatzort oder auf unterschiedliche Öffnungen in zu entlastenden Behältern usw. ist dadurch nicht ohne weiteres möglich.Another feature of the previous designs is that the shape of the device and also of the inlet opening is fixed by the outer basket or the outer housing. An adaptation of the device to different spatial conditions at the place of use or to different openings in containers to be relieved, etc. is thus not readily possible.
Hier setzt die Erfindung an.This is where the invention starts.
Der Erfindung lag das Problem zugrunde eine Vorrichtung zur flammenlosen Druckentlastung einfacher zu gestalten und die für die Druckentlastung wirksame Fläche zu vergrößern.The invention was based on the problem of making a device for flameless pressure relief simpler and to increase the effective area for the pressure relief.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass als eine äußere Lage eine aus einem textilen Flächengebilde oder einem textilen Körpergebilde gebildete Hülle vorgesehen ist, wobei in dem von der Hülle eingeschlossenen Raum die inneren Lagen aufgenommen sind und die Hülle und die inneren Lagen eine Eintrittsöffnung für den Eintritt von Gasen und/oder Flammen in den von der Hülle, den inneren Lagen eingeschlossenen Raum aufweisen. Die Eintrittsöffnung kann an eine mit einer Berstscheibe verschlossene Öffnung des abzusichernden Behälters angeschlossen werden.This object is achieved in that is provided as an outer layer of a fabric formed from a fabric or a textile body shell, wherein in the space enclosed by the shell, the inner layers are received and the shell and the inner layers an inlet opening for the Entry of gases and / or flames in the space enclosed by the shell, the inner layers. The inlet opening can be connected to a closed with a rupture disc opening of the container to be secured.
Vorzugsweise ist die Hülle und/oder die wenigstens eine innere Lage selbsttragend, das heißt, die Hülle und/oder die wenigstens eine innere Lage geben den äußeren und/oder inneren Lagen eine Steifigkeit, so dass die Form des von der wenigstens einen inneren Lage eingeschlossenen Raums vorgegeben ist. Alternativ oder ergänzend kann ein Traggestell zwischen der wenigstens einen inneren Lage und der Hülle vorgesehen sein, welches der Hülle und/oder der wenigstens einen inneren Lage eine zusätzliche Steifigkeit gibt.Preferably, the sheath and / or the at least one inner layer is self-supporting, that is, the sheath and / or the at least one inner layer give the outer and / or inner layers a stiffness, so that the shape of the enclosed by the at least one inner layer Space is given. Alternatively or In addition, a support frame between the at least one inner layer and the shell may be provided, which gives the shell and / or the at least one inner layer an additional rigidity.
Das Traggestell kann eine Eintrittsöffnung für den Eintritt von Gasen, Staub und/oder Flammen in den von der Hülle, dem Traggestell und den inneren Lagen eingeschlossenen Raum aufweisen.The support frame may have an inlet for the entry of gases, dust and / or flames in the enclosed space of the shell, the support frame and the inner layers.
Die Hülle, die mindestens eine innere Lage und/oder das Traggestell kann so flexibel sein, das die äußere Form an die Platzverhältnisse am Einbauort angepasst werden können, ohne dass die Vorrichtung ausgetauscht werden muss. Ebenso ist es möglich, dass die genannten Komponenten so flexibel sind, dass sie an unterschiedliche Öffnungen von abzusichernden Behältern angepasst werden können. So kann die Vorrichtung zum Beispiel auf runde oder eckige Öffnungen angepasst werden.The shell, the at least one inner layer and / or the support frame can be so flexible that the outer shape can be adapted to the space conditions at the installation site, without having to replace the device. It is also possible that the components mentioned are so flexible that they can be adapted to different openings of containers to be protected. For example, the device can be adapted to round or square openings.
Es ist möglich, dass unabhängig von der äußeren Form der äußeren Lage bzw. die Hülle bei einer Entlastung die durch die äußere Lage oder die Hülle austretenden Gase in einer zur äußeren Lage parallelen Front senkrecht zur äußeren Oberfläche der äußeren Lage fortschreitet. Diese Art der Entlastung wird konturparallele Entlastung oder auch "contour parallel venting (cpv)" genannt.It is possible that, regardless of the outer shape of the outer layer or the shell during a discharge, the gases exiting through the outer layer or the sheath in a front parallel to the outer layer front perpendicular to the outer surface of the outer layer progresses. This type of relief is called contour-parallel relief or "contour parallel venting (cpv)".
Ein Außenkorb oder Außengehäuse ist bei einer erfindungsgemäßen Vorrichtung zur flammenlosen Druckentlastung nicht notwendig. Die Funktion wird von einer Hülle übernommen, die wie die inneren Lagen aus einem textilen Flächengebilde oder einem textilen Körpergebilde aus Metallfäden oder Metalldrähten hergestellt ist. Zusätzlich kann ein Außenkorb oder ein Außengehäuse vorgesehen sein. Die Hülle ist an die Form der Anordnung aus dem Traggestell und/oder den inneren Lagen angepasst und hüllt diese ein. Dabei liegt die Hülle möglichst eng an der äußersten inneren Lage an. Bahnen aus textilen Flächengebilden können zu einem textilen Körpergebilde vernäht sein.An outer basket or outer housing is not necessary in a device according to the invention for flameless pressure relief. The function is taken over by a shell, which is made like the inner layers of a textile fabric or a textile body of metal threads or metal wires. In addition, an outer basket or an outer housing may be provided. The shell is to the shape of the arrangement of the support frame and / or the inner Adjusted layers and envelops them. The shell is as close as possible to the outermost inner layer. Webs of textile fabrics can be sewn into a textile body structure.
Während das Traggestell dafür vorgesehen ist, dass die inneren Lagen aus den textilen Flächengebilden oder den textilen Körpergebilden in einem Nichtgebrauchszustand nicht in sich zusammenfallen und den inneren Lagen eine hinreichende Stabilität gibt, so dass der über die Eintrittsöffnungen erreichbare und für die Druckentlastung notwendige Raum erhalten bleibt, sorgt die äußere Hülle dafür, dass sich die Lagen im Nichtgebrauchszustand wie auch im Gebrauchszustand nicht ablösen und durch die Gegend fliegen.While the support frame is provided for the fact that the inner layers of textile fabrics or textile body structures do not coincide in a non-use state and the inner layers sufficient stability, so that the space accessible via the inlet openings and necessary for the pressure relief space is maintained , The outer shell ensures that the layers do not detach in the non-use state as well as in use and fly through the area.
Es kann genau eine Hülle vorgesehen sein. Es ist aber auch möglich, dass die erfindungsgemäße Vorrichtung zwei oder mehr Hüllen aufweist, wobei die Hüllen wie Zwiebelschalen einander und die inneren Lagen und das Traggestell einhüllen.It can be provided exactly a shell. However, it is also possible for the device according to the invention to have two or more sheaths, the sheaths, like onion shells, enveloping one another and the inner layers and the support frame.
Die Hülle kann aus mehreren Bahnen aus textilen Flächengebilden zusammenfügt, insbesondere zusammen genäht sein. Es ist aber auch möglich, dass die Hülle schon bei der Herstellung, also beim Weben, Stricken oder Wirken ihre Form erhält und ein textiles Körpergebilde ist.The sheath can be composed of several webs of textile fabrics, in particular sewn together. But it is also possible that the shell already in the production, ie when weaving, knitting or working receives its shape and is a textile body structure.
Die Vorrichtung kann einen Rahmen aufweisen, der eine Eintrittsöffnung der Vorrichtung für den Eintritt von Gasen, Staub und/oder Flammen in den von der Hülle, den inneren Lagen und dem Traggestell eingeschlossenen Raum begrenzt.The apparatus may comprise a frame defining an inlet opening of the device for the entry of gases, dust and / or flames in the enclosed space of the shell, the inner layers and the support frame.
Das Traggestell kann mit dem Rahmen verbunden sein. Dann kann der Rahmen auch die Eintrittsöffnung des Traggestells begrenzen.The support frame can be connected to the frame. Then the frame can also limit the inlet opening of the support frame.
Der Rahmen kann eine runde oder mehreckige, insbesondere viereckige, sechseckige oder achteckige Eintrittsöffnung begrenzen.The frame may define a round or polygonal, in particular square, hexagonal or octagonal entry opening.
Ebenso ist es möglich, dass die inneren Lagen und/oder die Hülle mit dem Rahmen verbunden sind. Der Rahmen kann dann auch die Eintrittsöffnungen der inneren Lagen und/oder der Hülle begrenzen.It is also possible that the inner layers and / or the shell are connected to the frame. The frame can then also limit the inlet openings of the inner layers and / or the shell.
Der Rahmen kann einen Kragen aufweisen, der zur Verbindung mit einem abzusichernden Gegenstand geeignet und eingerichtet ist. In dem Kragen können beispielsweise Bohrungen für Verschraubungen des Rahmens - und damit der gesamten Vorrichtung - an einer Entlastungsöffnung eines abzusichernden Gebäudes oder Gefäßes vorgesehen sein.The frame may have a collar suitable and arranged for connection to an object to be secured. In the collar, for example, holes for screwing the frame - and thus the entire device - be provided at a relief opening of a building or vessel to be protected.
Die Hülle kann zumindest abschnittsweise die Form eines Kugelabschnitts haben. Ebenso ist es möglich, dass die Hülle einer erfindungsgemäßen Vorrichtung trogartig, spärenförmig oder oval geformt ist.The shell can at least partially have the shape of a spherical segment. It is also possible that the sheath of a device according to the invention is trough-shaped, spherical or oval shaped.
Es hat sich gezeigt, dass es für die Befestigung der Hülle von Vorteil ist, wenn sich der von der Hülle eingeschlossene Raum in Richtung der Eintrittsöffnung verjüngt. Die inneren Lagen und das Traggestell ragen dann nicht nur in die Hülle hinein, sie hintergreifen dann auch die Eintrittsöffnung der Hülle, was dazu führt, dass die Hülle nicht von den inneren Lagen und dem Traggestell abrutschen kann.It has been found that it is advantageous for the attachment of the shell when the space enclosed by the shell tapers in the direction of the inlet opening. The inner layers and the support frame then not only protrude into the shell, they then also engage behind the inlet opening of the shell, with the result that the shell can not slip off the inner layers and the support frame.
Die Metallfäden und/oder das Metallgeflecht, aus denen die textilen Flächengebilde oder die textilen Körpergebilde herstellt sind, können Edelstahlfäden sein. Es liegt aber im Rahmen der Erfindung, auch Fäden aus anderen Metallen oder Legierungen oder nichtmetallischen Materialen zu verwenden.The metal threads and / or the metal mesh from which the textile fabrics or textile body structures are made can be stainless steel threads. However, it is within the scope of the invention to use filaments of other metals or alloys or non-metallic materials.
Die textilen Flächengebilde oder die textilen Körpergebilde unterschiedlicher Lagen können auch aus verschiedenen Metallfäden hergestellt sein. Es ist sogar möglich, das zwischen den Lagen aus den Flächengebilden aus Metallfäden Lagen vorgesehen sind, die aus einem Kunststoff oder anderen nichtmetallische Materialen hergestellt sind. Auch dabei kann es sich um ein textiles Flächengebilde oder ein textiles Körpergebilde handeln. Dieses kann dann aus Kunststofffäden oder Kunstfasern hergestellt sein. Insbesondere die Hülle einer erfindungsgemäßen Vorrichtung kann aus einem textilen Flächengebilde oder einem textilen Körpergebilde aus Kunststofffäden hergestellt sein.The textile fabrics or the textile body structures of different layers can also be made of different metal threads. It is even possible that between the layers of the fabrics of metal filaments layers are provided, which are made of a plastic or other non-metallic materials. This can also be a textile fabric or a textile body structure. This can then be made of plastic threads or synthetic fibers. In particular, the shell of a device according to the invention can be made of a textile fabric or a textile body structure made of plastic threads.
Zumindest eines der textilen Flächengebilde oder der textilen Körpergebilde kann ein Gewebe, ein Gewirk, ein Gestrick, ein Geflecht, ein Vliesstoff oder ein Filz sein.At least one of the textile fabrics or the textile body structures may be a woven fabric, a knitted fabric, a knitted fabric, a braid, a nonwoven fabric or a felt.
Vorzugsweise ist die Eintrittsöffnung einer erfindungsgemäßen Vorrichtung mittels einer Berstscheibe verschlossen, die an dem Rahmen angebracht sein kann.Preferably, the inlet opening of a device according to the invention is closed by means of a bursting disc, which can be attached to the frame.
