Abstract

A soot blower is attached in a hinged fashion to the wall (1) of a heat exchanger, and suspended on a frame via a lever strutting. The lever strutting consists of two double-armed levers (12, 13), which are mounted in each case in a lever bearing (14, 15) and are connected to one another via a coupling hinge (17). The free end of one lever (12) is connected in a hinged fashion to the wall (1) of the heat exchanger, and the free end of the other lever (13) is connected in a hinged fashion to the soot blower. The lever bearings (14, 15) are suspended on the frame and can, just like the coupling hinge (17) be displaced in the longitudinal direction of the lever (12, 13). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Aufhängen einer Rußbläsereinheit mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a device for hanging a sootblower unit with the features of the preamble of claim 1.

Die Wärmedehnungen, denen Wärmetauscher und Kessel im Betrieb ausgesetzt sind, werden auf die mit dem Wärmetauscher verbundenen Rußbläser übertragen. Bei Rußbläsern, bei denen durch einen außenliegenden Antriebsteil im Kessel geführte Reinigungselemente wie etwa Blasrohre oder Traversen bewegt werden, treten durch die Wärmedehnungen relatiy zu diesen Führungen Lageveränderungen auf, die zu mechanischen Schwergängigkeiten führen. Bei sehr kurzen Rußbläsern reicht es aus, den Antriebsteil mit der Vorderseite direkt mit der Wand des Wärmetauschers zu verbinden. Auf diese Weise folgt der Rußbläser den Bewegungen der Wand und der sich entsprechend verschiebenden Aufhängepunkte für die Führungen im Wärmetauscher.The thermal expansions to which the heat exchanger and boiler are exposed during operation are transferred to the sootblowers connected to the heat exchanger. In sootblowers, in which cleaning elements such as blowpipes or traverses are moved by an external drive part in the boiler, changes in position occur due to the thermal expansion relative to these guides, which lead to mechanical stiffness. In the case of very short sootblowers, it is sufficient to connect the front of the drive section directly to the wall of the heat exchanger. In this way, the soot blower follows the movements of the wall and the correspondingly moving suspension points for the guides in the heat exchanger.

Bei längeren und schweren Antriebsteilen ist außer der vorderen Befestigung ein zweiter Aufhängungspunkt am hinteren Ende erforderlich, der zum Beispiel mit Hilfe einer Zugstange wiederum mit der Wand des Wärmetauschers verbunden ist. Auf diese Weise kann der Rußbläser seine Lage relativ zur Wand beibehalten. Damit kleine Relativdehnungen zwischen den beiden Befestigungspunkten an der Wand aufgenommen werden können, werden diese und der hintere Aufhängepunkt am Rußbläserantriebsteil häufig drehbar ausgeführt. Diese Aufhängung hat jedoch den Nachteil, daß für lange Antriebsteile entsprechender Platz vorhanden sein muß, damit die Zugstange zur Wand geführt werden kann. Dies stößt in der Praxis häufig auf Schwierigkeiten, da der Raum über dem Rußbläser wegen anderer Bauteile wie Gerüstträger, Bühnen, Rohrleitungen oder dergleichen belegt ist.In the case of longer and heavy drive parts, a second suspension point is required at the rear end in addition to the front attachment, which in turn is connected to the wall of the heat exchanger with the aid of a pull rod. In this way, the sootblower can maintain its position relative to the wall. So that small relative strains between the two attachment points on the wall can be absorbed, these and the rear suspension point on the soot blower drive part are often designed to be rotatable. However, this suspension has the disadvantage that there must be sufficient space for long drive parts so that the pull rod can be guided to the wall. In practice, this often encounters difficulties, since the space above the soot blower is occupied due to other components such as scaffold girders, platforms, pipes or the like.

Man hat weiterhin schon Rußbläser am hinteren Ende mit einem Seil aufgehängt, das über Rollen geführt und an der Kesselwand angeschlagen wurde, damit der Rußbläser den Wärmedehnungen folgt. Diese Konstruktion hat sich jedoch in der Durchführung als relativ schwierig und nachteilig erwiesen. Problematisch ist die nicht vollständig zu verhindernde Längung des Seiles während des Betriebes, die eine dauernde Nachjustierung der Aufhängung erforderlich macht.The sootblower has also been suspended at the rear end with a rope that was guided over rollers and attached to the boiler wall so that the sootblower follows the thermal expansion. However, this construction has proven to be relatively difficult and disadvantageous to implement. The problem is that the rope cannot be prevented from being fully prevented during operation, which necessitates constant readjustment of the suspension.

Auch ist eine Lageveränderung des Rußbläsers durch die Bewegungen der mit dem Bläserventil verbundenen Rohrleitung nicht zu verhindern, da das Seil nur Zugkräfte aufnimmt.A change in position of the soot blower cannot be prevented by the movements of the pipeline connected to the blower valve, since the cable only absorbs tensile forces.

Der Erfindung liegt die Aufgabe zugrunde, die Rußbläsereinheit derart aufzuhängen, daß sie ihre vertikale Lage relatiy zum Wärmetauscher sicher beibehält und wenig Platz beansprucht.The invention has for its object to hang the soot blower unit so that it maintains its vertical position relative to the heat exchanger safely and takes up little space.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the characterizing features of claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Die im Betrieb auftretenden Wärmedehnungen in vertikaler Richtung werden durch das Hebelgestänge aufgefangen, wobei dieses Hebelgestänge wenig Raum oberhalb der Rußbläsereinheit beansprucht. Horizontale Wärmedehnungen und Horizontalbewegungen infolge der Schrägstellung der Hebel werden durch die Verschiebbarkeit der Hebellager und des Kopplungslagers aufgefangen.The thermal expansion occurring in operation in the vertical direction is absorbed by the lever linkage, this lever linkage taking up little space above the soot blower unit. Horizontal thermal expansion and horizontal movements due to the inclination of the levers are absorbed by the displaceability of the lever bearings and the coupling bearing.

Von einem Wärmetauscher oder einem Kessel ist nur die äußere Wand 1 dargestellt. Zum Reinigen der Wärmetauscherflächen im Inneren des Wärmetauschers dienen Rußbläsereinheiten, von denen in der Zeichnung eine gezeigt ist. Die Rußbläsereinheit besteht aus einem Lanzenrohr 2, das am vorderen Ende z. B. mit einer im Kessel geführten Blastraverse verbunden und über ein Innenrohr 4 geführt ist. Am hinteren Ende des Innenrohres 4 ist ein Bläserventil 5 vorgesehen, durch das dem Lanzenrohr 2 über das Innenrohr 4 ein Blasmedium zum Beispiel Wasserdampf zugeführt wird. Das Lanzenrohr 2 wird in Längsrichtung verschoben und durch einen an der Wand 1 befestigten Wandkasten 6 in das Innere des Wärmetauschers gefahren.Only the outer wall 1 of a heat exchanger or a boiler is shown. Sootblower units, one of which is shown in the drawing, are used to clean the heat exchanger surfaces inside the heat exchanger. The soot blower unit consists of a lance tube 2, the z. B. connected to a blast traverse guided in the boiler and guided over an inner tube 4. At the rear end of the inner tube 4, a blower valve 5 is provided, through which the Lance tube 2 is supplied with a blowing medium, for example water vapor, via the inner tube 4. The lance tube 2 is displaced in the longitudinal direction and driven into the interior of the heat exchanger through a wall box 6 fastened to the wall 1.

Das Lanzenrohr 2 der Rußbläsereinheit ist mit einem Bläserwagen 7 verbunden, der über einen Motor 8 angetrieben ist. Ein auf der Abtriebswelle des Motors 8 angebrachtes Ritzel greift in eine Zahnstange 9 ein, die mit einem Fahrträger 10 verbunden ist.The lance tube 2 of the soot blower unit is connected to a blower carriage 7 which is driven by a motor 8. A pinion mounted on the output shaft of the motor 8 engages in a toothed rack 9 which is connected to a drive carrier 10.

Der Fahrträger 10 der Rußbläsereinheit ist gelenkig an dem Wandkasten 6 befestigt und außerdem über ein Hebelgestänge an einem Gerüstträger 11 eines feststehenden Gerüstes aufgehängt. In dem Gerüst ist der Wärmetauscher aufgehängt, so daß sich dieser gegenüber dem Gerüst infolge Wärmedehnung verschieben kann.The drive bracket 10 of the sootblower unit is articulated to the wall box 6 and is also suspended from a scaffold bracket 11 of a stationary scaffold via a lever linkage. The heat exchanger is suspended in the frame, so that it can move relative to the frame due to thermal expansion.

Das Hebelgestänge besteht aus zwei zweiarmigen Hebeln 12, 13, die um ein Hebellager 14, 15 schwenkbar sind. Die beiden Hebellager 14, 15 sind an dem Gerüstträger 11 mit Hilfe von vier vertikalen U-Eisen 16 aufgehängt, die paarweise an zwei gegenüberliegenden Seiten der Hebel 12, 13 anliegen. Vorzugsweise sind die beiden Hebel 12, 13 gleich lang, und auch die auf den Hebeln 12, 13 gebildeten Hebelarme weisen gleiche Längen auf.The lever linkage consists of two two-armed levers 12, 13 which are pivotable about a lever bearing 14, 15. The two lever bearings 14, 15 are suspended from the scaffold support 11 with the aid of four vertical U-irons 16, which bear in pairs on two opposite sides of the levers 12, 13. The two levers 12, 13 are preferably of the same length, and the lever arms formed on the levers 12, 13 also have the same lengths.

Die beiden Hebel 12, 13 sind durch ein Kopplungsgelenk 17 miteinander verbunden. Das freie Ende des ersten Hebels 12 ist über ein an der Wand 1 des Wärmetauschers befestigtes Gelenk 18 gehalten. An dem freien Ende des zweiten Hebels 13 ist über Stangen 19 der Fahrträger 10 der Rußbläsereinheit gelenkig aufgehängt.The two levers 12, 13 are connected to one another by a coupling joint 17. The free end of the first lever 12 is held by a joint 18 fastened to the wall 1 of the heat exchanger. At the free end of the second lever 13, the carriage 10 of the soot blower unit is articulated via rods 19.

Wie aus den Fig. 2 und 3 zu erkennen ist, enthält das Hebellager 14 einen Bolzen 20, der in einer mit dem Hebel 12 verbundenen Gelenklasche 21 gehalten ist. Das Hebellager 14 ist um einen gewissen Betrag in Längsrichtung des Hebels 12 verschiebbar. Zu diesem Zweck sind an jeweils zwei vertikalen, mit dem Gerüstträger 11 verbundenen U-Eisen 16 in einem vertikalen Abstand voneinander zwei horizontale U-Eisen 22 befestigt, die den Bolzen 20 unter- und übergreifen. Die horizontalen U-Eisen 22 bilden zwischen sich eine Gleitbahn, die durch die vertikalen U-Eisen 16 nach Art eines Langloches begrenzt ist und in der sich der Bolzen 20 verschieben kann.As can be seen from FIGS. 2 and 3, the lever bearing 14 contains a bolt 20 which is held in a joint plate 21 connected to the lever 12. The lever bearing 14 is displaceable by a certain amount in the longitudinal direction of the lever 12. For this purpose, two horizontal U-bars 22 are attached to two vertical U-bars 16 connected to the scaffold support 11 at a vertical distance from one another, which reach under and overlap the bolt 20. The horizontal U-irons 22 form a slideway between them is limited by the vertical U-iron 16 in the manner of an elongated hole and in which the bolt 20 can move.

Das Hebellager 15 des zweiten Hebels 13 ist in gleicher Weise, und das Kopplungsgelenk 17 ist in ähnlicher Weise aufgebaut und in Längsrichtung der Hebel 12, 13 verschiebbar. Die horizontale Verschiebung, die auf diese Weise möglich wird, kann zum Beispiel 30 mm betragen.The lever bearing 15 of the second lever 13 is in the same way, and the coupling joint 17 is constructed in a similar manner and is movable in the longitudinal direction of the levers 12, 13. The horizontal shift that is possible in this way can be, for example, 30 mm.

An dem hinteren Ende des Gerüstträgers 11 ist ein Querträger 23 und an diesem sind zwei Führungsstangen 24 senkrecht befestigt. Diese Führungsstangen 24 liegen an den Längsseiten des Fahrträgers 10 der Rußbläsereinheit an und sichern die Rußbläsereinheit gegen ein Verkanten. Die ein solches Verkanten bewirkenden Kräfte stammen zum Beispiel aus dem Rohrsystem, das an das Bläserventil 5 angeschlossen ist.At the rear end of the scaffold bracket 11 is a cross member 23 and two guide rods 24 are vertically attached to this. These guide rods 24 rest on the long sides of the carriage 10 of the sootblower unit and secure the sootblower unit against tilting. The forces causing such tilting originate, for example, from the pipe system which is connected to the blower valve 5.

Wenn sich der in dem Gerüst aufgehängte Wärmetauscher während des Betriebes auf Grund der Wärmebelastung dehnt, wandern zusammen mit der Wand 1 auch der gelenkige Befestigungspunkt des Fahrträgers 10 und das Gelenk 18 des Hebelgestänges nach unten. Dabei nimmt das Gelenk 18 den ersten Hebel 12 mit nach unten, wodurch sich dieser Hebel 12 schräg stellt. Über die Kopplung durch das Kopplungsgelenk 17 nimmt der zweite Hebel 13 eine entgegengesetzte Stellung ein, wodurch das mit dem Fahrträger 10 gelenkig verbundene Ende des zweiten Hebels 13 sich nach unten bewegt. Auf Grund der eingestellten geometrischen Verhältnisse des Hebelgestänges ist die Weglänge, die das Gelenk 18 und der Befestigungspunkt des Fahrträgers 10 zurücklegen, gleich der Weglänge, die das hintere Ende des zweiten Hebels 13 beschreibt. Damit wird die Rußbläsereinheit parallel zu sich verschoben. Eine bei der Hebelbewegung sich ergebende Horizontalverschiebung wird durch die verschiebbar angeordneten Hebellager 14, 15 und das verschiebbare Kopplungsgelenk 17 aufgenommen. Das gleiche gilt für eine horizontale Wärmedehnung des Wärmetauschers. Eine Querdehnung des Wärmetauschers, die nur ein geringes Maß annimmt, wird durch das Spiel in den Gelenken und der Lager aufgefangen.If the heat exchanger suspended in the scaffold expands during operation due to the heat load, the articulated fastening point of the travel carrier 10 and the joint 18 of the lever linkage also move downward together with the wall 1. The joint 18 takes the first lever 12 downwards, as a result of which this lever 12 is inclined. Via the coupling through the coupling joint 17, the second lever 13 assumes an opposite position, as a result of which the end of the second lever 13, which is articulated to the travel carrier 10, moves downward. Due to the set geometric relationships of the lever linkage, the path length covered by the joint 18 and the attachment point of the travel carrier 10 is equal to the path length described by the rear end of the second lever 13. This will move the sootblower unit parallel to itself. A horizontal displacement resulting from the lever movement is absorbed by the displaceably arranged lever bearings 14, 15 and the displaceable coupling joint 17. The same applies to horizontal thermal expansion of the heat exchanger. A transverse expansion of the heat exchanger, which takes up only a small amount, is absorbed by the play in the joints and the bearings.
