Abstract

Support grid is for use in a packed tower and consists of a set of earthenware slats mounted in a succession of circular rows radiating from the centre to form an arched support. Successive rows are offset w.r.t. each other to form a progressively rising effect from the outer walls. The proportion of rise to length for each successive row is constant. Tbe height of the rise is equal to height of the packing piece. Used in packed columns. Conventional curved grids have the problem that if a primary layer of rings is added, these can become damaged due to distortion. Further damage occurs if saddles are laid on top of these.

Description

Tragrost für üllkörpertürmeSupport grate for towers

Die Erfindung betrifft einen Tragrost für Füllkörpertürme bestehend aus in konzentrischen Ringreihen, in jeder Ringreihe unter sich austauschbar gleichen, gegen die Steine benachbarter Reihen versetzt angeordneten, zu einem kugelabschnittsförmigen Bogengewölbe zusammengesetzten ringsektorförmigen Roststeinen nach der Gattung des Hauptanspruchs.The invention relates to a support grid for tower packing in concentric rows of rings, in each row of rings interchangeably the same, arranged offset from the stones of adjacent rows to form a spherical segment Arched vaults composed of ring-sector-shaped rust stones according to the genus Main claim.

Bei einem bekannten Tragrost dieser Gattung (DE-PS 16 84 971) bilden die Oberseiten der Roststeine in Einbaulage eine der Bogengewölbeform entsprechende gekrümmte Auflagefläche für die Füllkörper. Bei Verwendung einer sogenannten Zwischenschicht von üllkörpern, die aus kurzen zylindrischen Rohrstücken bestehen, auf die dann die eigentliche Arbeitsschicht vorzugsweise sattelförmiger Füllkörper aufgebracht wird, bringt diese Form des Tragrostes Schwierigkeiten mit sich, weil die zylindrischzn Rohrstücke der Zwischenschicht mit ihren Außenflächen richt dicht aneinander legbar sind und je nach der Größe des Gewölberadius beim Aufbringenauf den Tragrost kippen und dadurch Störungen verursachen. Beim Auffüllen der Arbeitsschicht ar die Zwischenschicht ergeben sich ferner außermittige Belastungen und Kantendrücke auf die Körper der Zwischenschicht, die zu deren Beschädigung oder Zerstörung führen können.Form in a known support grid of this type (DE-PS 16 84 971) the tops of the grate stones in the installed position correspond to the arch shape curved support surface for the packing. When using a so-called intermediate layer of üllkkörperern, which consist of short cylindrical pieces of pipe, on which then the actual working layer is preferably applied with saddle-shaped fillers is, this form of the support grate with it difficulties, because the cylindischzn Pipe pieces of the intermediate layer with their outer surfaces can be placed tightly against one another and, depending on the size of the vault radius, tilt when placed on the support grid and thereby cause disruptions. When filling the work layer ar the intermediate layer there are also off-center loads and edge pressures on the body of the Intermediate layer, which can lead to their damage or destruction.

Der Erfindung liegt die Aufgabe zugrunde diese Nachteile zu beseitigen. Die Aufgabe wird dadurch gelöst, daß die den Tragrost bildenden Oberseiten der Rost steine der Ringreihen von der Iìostmitte nach außen absteigende Stufen bildend gegeneinander abgesetzt sind. Die in Einbaulage aufeinanderliegenden Wandungen der Steine zweier benachbarter Ringreihen sollen dabei eine die Höhe der Stufen bestimmende Längendifferenz aufweisen und ihre oberen Seiten in eara lellen horizontalen Ebenen liegen. Die Höhe der Stufen soll dabei gleich der Stehhöhe der Füllkörper der Zwischenschicht sein.The invention is based on the object of eliminating these disadvantages. The object is achieved in that the upper sides of the grate forming the support grate stones of the ring rows from the middle east to the outside forming descending steps against each other are discontinued. The one on top of the other in the installation position Walls of the stones in two adjacent rows of rings should be the same as the height of the steps have determining differences in length and their upper sides in eara lellen horizontal Levels lie. The height of the steps should be the same as the headroom of the packing be the intermediate layer.

Bei dieser Ausbildung des Tragrostes lassen sich die zylindrischen Rohrstücke der Zwischenschicht mit aneinanderliegenden Umfangsflächen auf die Oberseiten der Roststeine stellen, und es entsteht gegebenenfalls nach Bildung zweier oder mehrerer Schichten dieser Körper eine horizontal verlaufende Auflagefläche für die Füllkörper der eigentlichen Arbeitsschicht.With this design of the support grate, the cylindrical Pipe pieces of the intermediate layer with adjacent peripheral surfaces on the upper sides of the grate stones, and it may arise after the formation of two or several layers of this body have a horizontal support surface for the Packing of the actual work shift.

Die Erfindung wird anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigten #ig.l den Rost im Radialschnitt, Fig.2 einen Teil des Rostes in der Draufsicht und 11in.3 eine Einzelheit aus Fig.l in vergrößertem Maßstab.The invention is based on the embodiment shown in the drawing explained in more detail. In the drawing, # ig.l showed the grate in a radial section, Fig. 2 a part of the grate in plan view and 11in.3 a detail from Fig.l in enlarged scale.

Die Roststeine 2,3, 4,5,6 und 7 sind in Ringreihen gleicher Bezifferung um den gelochten zylindrischen Abschlußstein 6 herum zu einem kugelabschnittsförmigen Bogengewölbe zusamnengesetzt#in das Tragwerk 9 des nicht dargestellten Füllkörperturms eingesetzt. Die Roststeine bestehen beim Ausführungsbeispiel in bekannter, nicht zur Erfindung gehörenden Weise aus I-Profilen, die sich mit ihren unteren und oberen Flanschen gegeneinander abstützen (vergl. Fig.2) Die den Tragrost bildenden Oberseiten der Roststeine der einzelnen Ringreihen bilden wie aus Fig.l und Fig.3 ersichtlich von der Rostmitte nach außen absteigende Stufen. Wie aus Fig.3 zu ersehen, weisen die Wandungen der Steine, hier 3 und 4 bzw. 4 und 5 zweier benachbarter Ringreihen eine die Höhe der Stufen bestimmende Längendifferenz auf1 rund ihre oberen Seiten liegen in paralellen horizontalen Ebenen. Auf diese Weise ist es möglich, die Zylinderrohrabschnitte 10, die die sogenannte Füllkörper-Zwischenlage bilden, dicht nebeneinander stehend und sich mit ihren Außenumrnpen berührend auf die oberen Seiten der Steine 4 und 5 der entsprechenden Ringreihen aufzustellen. Da die Höhe der zwischen den einzelnen Ringreihen, hier 4und 5 gebildeten Stufen gleich der Stehhöhe der Rohre 10 ist, läßt sich über den auf der Ringreihe 5 aufstehenden Rohren 10 eine weitere Lage von Rohren t°x gleicher höhe unterbringerl, so daß für das anschließende Aufbringen der eigen;t#lichen(hier nicht dargestellten) Füllkörper der Arbeitsschicht gegebenenfalls eine horizontal verlaufende Auflageebene geschaffen werden kann.The grate stones 2, 3, 4, 5, 6 and 7 are in rows of rings with the same numbering around the perforated cylindrical end stone 6 to a spherical segment-shaped Arched vaults put together # in the supporting structure 9 of the packed tower, not shown used. The grate stones do not exist in the embodiment in known ones belonging to the invention way of I-profiles, which are with their lower and upper Support the flanges against each other (see Fig. 2) The upper sides forming the support grid the grate stones of the individual rows of rings form as shown in Fig.l and Fig.3 Steps descending from the center of the grate to the outside. As can be seen from Fig.3, show the walls of the stones, here 3 and 4 or 4 and 5 of two adjacent rows of rings a difference in length, which determines the height of the steps, on about their upper sides lie in parallel horizontal planes. In this way it is possible to use the cylinder tube sections 10, which form the so-called packing intermediate layer, standing close to one another and with their outer circumference touching the upper sides of the stones 4 and 5 of the corresponding rows of rings. Because the amount of between each Rows of rings, here 4 and 5 formed steps equal to the standing height of the pipes 10, can be on the upright on the row of rings 5 tubes 10 a further layer of pipes t ° x of the same height, so that for the subsequent application the intrinsic packing (not shown here) of the work shift, if applicable a horizontally running support plane can be created.
