Description

Die Erfindung bezieht sich auf eine Kammerrahmenabdichtung von Horizontalkammerverkokungsöfen gemäß Oberbegriff des ersten Anspruches.The invention relates to a chamber frame seal of horizontal chamber coking furnaces according to the preamble of the first claim.

Aus der DE-OS 27 28 411 ist eine derartige Vorrichtung zur Kammerrahmenabdichtung von Verkokungsofenbatterien bekannt, wobei hinter den Ankerständern eine Stahlplatte angeordnet ist, an der mittels Nieten über der Höhe mehrere Gußpanzer­platten befestigt sind. Diese Gußpanzerplatten erstrecken sich seitlich bis hinter die Kammerrahmen. Hinter dem Kammerrahmen und den äußeren Enden der Gußpanzer befindet sich dabei auf der dem Mauerwerk zugewandten Seite eine mehrfach geteilte profilierte Steinschutzleiste. Die Zwischenräume zwischen Ofenkopfmauerwerk, Steinschutzleiste, Kammerrahmen und dem Gußpanzer sind dabei mit hitzebeständigem Dichtungsmaterial, z. B. keramischen Fasermatten, ausgefüllt.From DE-OS 27 28 411, such a device for chamber frame sealing of coking furnace batteries is known, a steel plate being arranged behind the anchor stands, to which a plurality of cast armor plates are fastened by means of rivets above the height. These cast armor plates extend laterally to behind the chamber frames. Behind the chamber frame and the outer ends of the cast iron shell there is a multi-part profiled stone protection strip on the side facing the masonry. The spaces between the furnace head masonry, stone protection strip, chamber frame and the cast iron shell are covered with heat-resistant sealing material, e.g. B. ceramic fiber mats filled.

Aufgrund der üblichen großen Temperaturschwankungen und der damit verbundenen Wärmedehnungen und unterschiedlichen Verfor­mungen von Kammerrahmen und Gußpanzer hat es in der Vergangen­heit immer wieder Schwierigkeiten bereitet, für eine gute Kam­ merrahmenabdichtung zu sorgen. Insbesondere an den senkrech­ten, von außen erreichbaren Stemmfugen zwischen Gußpanzer und Kammerrahmen kam es leicht zu Undichtigkeiten, wenn die Dicht­materialien sich gelöst haben und aus den Stemmfugen herausge­fallen sind.Due to the usual large temperature fluctuations and the associated thermal expansions and different deformations of the chamber frame and cast iron shell, it has always been difficult in the past to get a good result to ensure frame sealing. Leakages easily occurred, particularly on the vertical caulking joints between the cast armor and the chamber frame, which can be reached from the outside, when the sealing materials have come loose and have fallen out of the caulking joints.

Aufgabe der Erfindung ist es, für eine dauerhafte gasdichte Kammerrahmenabdichtung zu sorgen.The object of the invention is to provide a permanent gas-tight chamber frame seal.

Die Erfindung wird durch die im Kennzeichen des ersten Anspru­ches angegebenen Merkmale gelöst. Weitere Ausführungsformen der Erfindung sind in den Unteransprüchen 2 bis 7 wiedergege­ben.The invention is achieved by the features specified in the characterizing part of the first claim. Further embodiments of the invention are given in subclaims 2 to 7.

Durch die Verwendung einer umlaufenden elastischen Membran­dichtungsplatte ist auch bei größeren Wärmedehnungen und grö­eren Verformungen des Kammerrahmens immer eine gleichbleiben­de vollständige Abdichtung zwischen Kammerrahmen und Stein­schutzleiste bzw. Ofenkopfmauerwerk gewährleistet, so daß im Bereich der Kammerrahmen und Wandschutzplatten keine Rohgas­emissionen auftreten. Dabei sorgen die umlaufenden elastischen Membrandichtungsplatten, die zweckmäßig mit einem umlaufenden Flacheisen an den Kammerrahmen bzw. die Steinschutzleiste ge­klemmt werden, für eine gleichbleibende Anpressung der als Weichdichtung ausgebildeten Dichtelemente.By using a circumferential elastic membrane sealing plate, even with larger thermal expansions and larger deformations of the chamber frame, a constant complete seal between the chamber frame and the stone protection strip or furnace head masonry is always guaranteed, so that no raw gas emissions occur in the area of the chamber frame and wall protection plates. The circumferential elastic membrane sealing plates, which are expediently clamped to the chamber frame or the stone protection strip with a circumferential flat iron, ensure constant pressure on the sealing elements designed as soft seals.

Selbst wenn die Weichdichtungen im laufenden Betrieb aufgrund von Teeransätzen an Elastizität verloren haben, werden sie durch die Membrandichtungsplatte weiterhin gegen die Dich­tungsflächen gepreßt. Dabei kann die Anpressung am freien Ende zusätzlich durch ein aktives Anpreßelement unterstützt werden. Diese Anpreßelemente können aus einem umlaufenden oder aus über den Umfang geteilten elastischen Rohren bestehen.Even if the soft seals have lost elasticity during operation due to tar deposits, they are still pressed against the sealing surfaces by the membrane sealing plate. The contact at the free end can also be supported by an active contact element. These pressure elements can consist of a circumferential or of elastic tubes divided over the circumference.

Alternatiy können die Anpreßelemente aber auch aus über den Umfang verteilt angeordneten federbelasteten Druckstößeln be­stehen, die in einer durchgehenden Bohrung des Kammerrahmens angeordnet sind und dessen Anpreßkräfte auf einfache Weise von außen einstellbar sind. Während früher die Gußpanzerung in der Regel über der Höhe verteilt aus einzelnen Platten von ca. 1 m Höhe bestanden, die mit einer durchgehenden vorderen elasti­schen Stahlplatte vernietet waren, sieht die Erfindung vor, daß über der gesamten Kammerhöhe eine durchgehende Wandschutz­platte, vorzugsweise aus Stahl, angeordnet ist, die mit seit­lichen Auflagenocken hinter am Kammerrahmen befindliche Gegen­nocken greift und daß Wandschutzplatte und Kammerrahmen im Zu­sammenwirken mit äußeren Befestigungslaschen eine feste Ver­bindung bilden.Alternatively, the pressure elements can also consist of spring-loaded pressure plungers distributed over the circumference, which are located in a continuous bore in the chamber frame are arranged and the contact forces are easily adjustable from the outside. Whereas in the past the cast armor usually consisted of individual panels of approx. 1 m in height distributed over the height, which were riveted to a continuous front elastic steel panel, the invention provides for a continuous wall protection panel, preferably made of steel, over the entire chamber height. is arranged, which engages with lateral support cams behind counter cams located on the chamber frame and that the wall protection plate and chamber frame form a fixed connection in cooperation with external fastening tabs.

Durch die dauerhafte erfindungsgemäße Abdichtung der Innensei­te des Kammerrahmens gegenüber der Steinschutzleiste bzw. dem Kopfmauerwerk, insbesondere auf die häufig problematische Ab­dichtung der senkrechten Stemmfuge zwischen Kammerrahmen und den Wandschutzplatten, kann verzichtet werden.The permanent sealing according to the invention of the inside of the chamber frame with respect to the stone protective strip or the head masonry, in particular the often problematic sealing of the vertical caulking joint between the chamber frame and the wall protection plates, can be dispensed with.

Die Erfindung wird anhand der beigefügten Figuren 1 und 2 bei­spielsweise näher erläutert.The invention is explained in more detail, for example, with reference to the attached FIGS. 1 and 2.

Die Figuren zeigen im Querschnitt einen Teil einer Hälfte der Ofenkopfkonstruktion, die vor der Heizwand angeordnet ist. Im Bereich der Läuferwand ist vor dem Ofenkopfmauerwerk (14) eine dünne metallische Steinschutzleiste (8) angeordnet, die einer­seits von dem Kammerrahmen (6) und andererseits von der Wand­schutzplatte (3) vor dem Ofenkopfmauerwerk (14) gehalten wird. Die Wandschutzplatte (3) steht senkrecht mit Abstand hinter dem Ankerständer (1) und wird mit Hilfe von federbelasteten Druckstößeln (2) gehalten. Über an sich bekannte an der Wand­schutzplatte (3) angeordnete Befestigungslaschen (4) wird der Kammerrahmen (6) von außen gehalten. Auf der inneren Seite liegt der Kammerrahmen mit Gegennocken (7) an seitlichen Auf­lagenocken der Wandschutzplatte auf. An einem zum Ofenmauer­werk gerichteten inneren Vorsprung des Kammerrahmens (6) ist über den gesamten Umfang die Membrandichtungsplatte (12) mit Hilfe von Flacheisen (9) und Befestigungsschrauben (10) ver­ schraubt. Das freie zur Heizwandmitte gerichtete Ende der Mem­brandichtungsplatte (12) ist am Ende zur Steinschutzleiste (8) hin umgebogen, so daß zwischen der Membrandichtungsplatte (12) und der Steinschutzleiste (8) als Weichdichtelemente Dich­tungsschnüre (11) Platz finden. Zwischen Kammerrahmen (6) und der Membrandichtungsplatte (12) ist als zusätzliches Anpreß­element ein im eingebauten Zustand unter Spannung stehendes elastisches Rohr eingeklemmt (vgl. Figur 1).The figures show in cross section part of a half of the furnace head construction which is arranged in front of the heating wall. In the area of the rotor wall, a thin metallic stone protection strip (8) is arranged in front of the furnace head masonry (14), which is held on the one hand by the chamber frame (6) and on the other hand by the wall protection plate (3) in front of the furnace head masonry (14). The wall protection plate (3) stands vertically at a distance behind the anchor stand (1) and is held by means of spring-loaded pressure plungers (2). The chamber frame (6) is held from the outside by means of fastening tabs (4), known per se, on the wall protection plate (3). On the inner side, the chamber frame with counter cams (7) rests on the side support cams of the wall protection plate. On an inner projection of the chamber frame (6) facing the furnace masonry, the membrane sealing plate (12) is ver over the entire circumference with the aid of flat iron (9) and fastening screws (10) screws. The free end of the membrane sealing plate (12) facing the center of the heating wall is bent at the end towards the stone protection strip (8), so that sealing cords (11) can be found between the membrane sealing plate (12) and the stone protection strip (8) as soft sealing elements. Between the chamber frame (6) and the membrane sealing plate (12), an elastic tube which is under tension in the installed state is clamped as an additional contact element (cf. FIG. 1).

In der Figur 2 ist als aktives Anpreßelement anstelle des ela­stischen Rohres (13) ein von einer Schraubenfeder (20) gegen die Membrandichtungsplatte (12) gepreßter Druckstößel (19) an­geordnet. Dieser Druckstößel (19) ist in einer Bohrung des Kammerrahmens (6) geführt, wobei die Anpreßkraft von außen eingestellt werden kann. In den Figuren ist weiterhin zum Ab­bau der Temperatur vom heißen Ofenkopfmauerwerk nach außen bis zur Wandschutzplatte eine Isolierung (18) z. B. aus kerami­schem Material, Isolierplatten (17) und eine Stampfmasse (16) angeordnet. Zwischen der Steinschutzleiste (8) und dem Ofen­kopfmauerwerk (14) befindet sich eine Mörtelfuge (15). Bei der Verwendung dieser relativ dünnen Steinschutzleiste, die auch höheren Temperaturen ausgesetzt werden kann, kann die gesamte Läuferwand bis direkt hinter die Steinschutzleiste aus Silika­material ausgeführt sein. Auf die Zwischenschaltung von ein­zelnen Lagen von Schamottematerial kann verzichtet werden, da die Gefahr der Zerstörung von Silikamaterial aufgrund thermi­scher Spannungen auch in diesem Bereich der Ofenköpfe nicht besteht.In FIG. 2, a pressure tappet (19) pressed by a helical spring (20) against the diaphragm sealing plate (12) is arranged as an active pressure element instead of the elastic tube (13). This pressure tappet (19) is guided in a bore in the chamber frame (6), the contact pressure being adjustable from the outside. In the figures, an insulation (18) is also used to reduce the temperature from the hot furnace head masonry to the outside to the wall protection plate. B. made of ceramic material, insulating plates (17) and a ramming compound (16). A mortar joint (15) is located between the stone protection strip (8) and the furnace head masonry (14). When using this relatively thin stone protection strip, which can also be exposed to higher temperatures, the entire runner wall can be made of silica material right behind the stone protection strip. The interposition of individual layers of fireclay material can be dispensed with, since there is no risk of destruction of silica material due to thermal stresses in this area of the furnace heads either.
