Abstract

The invention relates to a device for supporting essentially horizontally extending pipes, especially ribbed pipes, which run parallel to one another such as the pipes of a waste heat boiler. The pipes, which are stacked on top of each other, have cylindrical sleeves (3) slid over them at set intervals and are supported via said sleeves on the corresponding sleeves of the pipes beneath. The bottom row sleeves (3) lie on support devices (6, 6') which are connected to a casing by suspension elements (7, 8). Said support devices (6, 6') and suspension elements (7, 8) are configured in such a way that they are at least partly cooled, and said cylindrical sleeves (3, 3') have an annular cross section. The device described exhibits the required resistance to higher temperatures since it is cooled, and also requires little labour to produce.

Description

Vorrichtunπ 7ur Aufiaαerung von im wesentlichen horizontal verlaufenden RohrenVorrichtunπ 7ur Aufiaαerung of substantially horizontal pipes
Die Erfindung betrifft eine Vorrichtung zur Auflagerung von im wesentlichen hoπzontal verlaufenden Rohren, insbesondere Rippenrohren, die parallel zueinander verlaufen, wie beispielsweise Rohre eines Abhitzekessels, wobei die übereinandergestapelten Rohre in bestimmten Abständen übergeschobene zylindrische Hülsen aufweisen und wobei sich die Rohre über die Hülsen an den entsprechenden Hülsen der darunterliegenden Rohre abstützen, die Hülsen der untersten Rohrreihe auf Trageinrichtungen, die über Hangee- iemente mit einem Gehäuse verbunden sind, aufliegen und die zylindrischen Huisen einen kreisπngformigen Querschnitt besitzen.The invention relates to a device for supporting essentially horizontally extending pipes, in particular finned pipes that run parallel to one another, such as pipes of a waste heat boiler, the stacked pipes having cylindrical sleeves pushed over at certain intervals and the pipes being attached to the corresponding sleeves Support the sleeves of the pipes underneath, the sleeves of the lowest row of pipes rest on supporting devices that are connected to a housing by hang elements, and the cylindrical sleeves have a circular cross-section.
Aus der AT 395 754 B ist eine Lochptatte zur vertikalen Abstützung von horizontalen Rohren vorzugsweise Rippenrohren, an einem Gehäuse insbesondere für Abhitzekessel oder Kondensatoren, bei der die Löcher für die Rohre entsprechend einem Teilungs- schema angeordnet sind und einen gegenüber dem Rohraußendurchmesser geringfügig größeren Querschnitt aufweisen, bekannt.AT 395 754 B discloses a perforated plate for the vertical support of horizontal tubes, preferably finned tubes, on a housing, in particular for waste heat boilers or condensers, in which the holes for the tubes are arranged according to a division scheme and have a slightly larger cross section than the outside diameter of the tube , known.
Die Erfindung weist den Nachteil auf, dass die Herstellung der Lochplatten durch Spanabhebung aufwendig ist, die hersteltungsbedingten Toleranzen sind oft so groß, dass der verbleibende Steg zwischen den Löchern schmal und die nötige Festigkeit der Lochplatte bei hohen Temperaturen, wie sie beispielsweise in einem Abhitzekessel herrschen, somit nicht gegeben ist und die Gefahr der Verformung der Lochpiatten besteht Weiters ist der Mindestabstand der Löcher festigkeitsmäßig vorgegeben, sodass eine größere Rohrdichte nicht verwirklicht werden kann.The invention has the disadvantage that the production of the perforated plates by chip removal is complex, the manufacturing tolerances are often so large that the remaining web between the holes is narrow and the necessary strength of the perforated plate at high temperatures, such as those prevailing in a waste heat boiler , is not given and there is a risk of deformation of the perforated plates. Furthermore, the minimum spacing of the holes is specified in terms of strength, so that a greater pipe density cannot be achieved.
Aus der US 4 245 694 ist eine Vorrichtung zur Auflagerung von Warmetauscherrohren bekannt, die aus einer Vielzahl von zylindrischen Hülsen oder ähnlichen Elementen besteht, durch welche die Warmetauscherrohre hindurchtreten, wobei die Hülsen in einem Rahmen angeordnet sind. Diese Vorrichtung weist bei höheren Abgastemperaturen nicht die notwendige Festigkeit auf.From US 4 245 694 a device for supporting heat exchanger tubes is known, which consists of a plurality of cylindrical sleeves or similar elements through which the heat exchanger tubes pass, the sleeves being arranged in a frame. This device does not have the necessary strength at higher exhaust gas temperatures.
Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine Auflagerung für die Rohre zu entwickeln, die bei höheren Temperaturen die notwendige Festigkeit besitzt und deren Herstellung im Vergleich zur AT 395 754 B mit geringem Arbeitsaufwand möglich ist. Die Erfindung ist dadurch gekennzeichnet, dass zumindest eine Trageinrichtung und die zugehörigen Hängeelemente zumindest teilweise gekühlt ausgebildet sind und die Trageinrichtung als durchströmter Sammler und die Hängeelemente als Zu- bzw Ableitungsrohre dieses Sammlers ausgebildet sind.The object of the present invention is now to develop a support for the pipes, which has the necessary strength at higher temperatures and whose manufacture is possible in comparison with AT 395 754 B with little effort. The invention is characterized in that at least one carrying device and the associated hanging elements are at least partially cooled and the carrying device is designed as a flow-through collector and the hanging elements as supply and discharge pipes of this collector.
Neu an dieser Erfindung ist, dass durch die zumindest teilweise Kühlung der Tragvo- richtung und der Hängeelemente die gekühlten Teile in den Kreislauf eines Abhitzekessels eingebunden und bei hohen Abgastemperaturen gekühlt werden, sodass die Hitzebeständigkeit der gekühlten Teile erhöht wird, wodurch die Temperaturbeständigkeit der Vorrichtung gegeben ist.What is new about this invention is that the at least partial cooling of the carrying device and the hanging elements integrates the cooled parts into the circuit of a waste heat boiler and cools them at high exhaust gas temperatures, so that the heat resistance of the cooled parts is increased, which gives the device the temperature resistance is.
Eine Ausgestaltung der Erfindung besteht darin, dass gekühlte Trageinrichtungen bzw gekühlte Hängeelemente mit ungekü lten Trägern bzw ungekühlten Hängeelementen kombiniert sind.One embodiment of the invention is that cooled support devices or cooled suspension elements are combined with uncooled carriers or uncooled suspension elements.
Das hat den Vorteil, dass die Trageinrichtungen bzw Hängeelemente mit höherer Temperaturbelastung mit Medium durchströmt, also gekühlt werden und die weniger temperaturbelasteten Vorrichtungen einfacher ausgeführt werden können, indem sie ungekühlt ausgebildet werden.This has the advantage that medium flows through the support devices or hanging elements with a higher temperature load, that is, they are cooled, and the less temperature-loaded devices can be designed more easily by being designed without cooling.
Die Mittelpunkte der Hülsen einer Rohrreihe können jeweils im Ausmaß eines Hülsenradius gegenüber der darunterliegenden Rohrreihe versetzt sein, wodurch eine besonders dichte Anordnung der Rohre gewährleistet ist.The centers of the sleeves of a row of tubes can each be offset to the extent of a sleeve radius relative to the row of tubes below, which ensures a particularly dense arrangement of the tubes.
Die Mittelpunkte der Hülsen einer Rohrreihe können weiters jeweils senkrecht über den Hülsen der darunterliegenden Rohrreihe angeordnet sein. Diese fluchtende Anordnung der Rohre bedingt eine weniger dichte Packung der Rohre und somit etwas mehr Raum für das zwischen den Rohren durchströmende Abgas.The centers of the sleeves of a row of tubes can also be arranged vertically above the sleeves of the row of tubes below. This aligned arrangement of the pipes results in a less tight packing of the pipes and thus a little more space for the exhaust gas flowing between the pipes.
Die Hülsen sind im Bereich der gegenseitigen Berührungslinien miteinander verschweißt. Dadurch wird die gegenseitige Lage der Hülsen dauerhaft festgelegt.The sleeves are welded together in the area of mutual contact lines. As a result, the mutual position of the sleeves is permanently determined.
Bei Ausbildung der Rohre als Rippenrohre liegen mindestens zwei Rippen auf einer Hülse auf, sodass das Rohr stabil gelagert ist.When the tubes are designed as finned tubes, at least two fins rest on a sleeve, so that the tube is stably supported.
Die Erfindung ist in den Figuren 1 bis 4 beispielhaft und schematisch dargestellt.The invention is shown by way of example and schematically in FIGS. 1 to 4.

In Fig. 1 sind zwei übereinanderliegende Rippenrohre 1 , 1 ' dargestellt, die durch RippenIn Fig. 1 two superimposed finned tubes 1, 1 ' are shown, which by fins
2, 2' auf der Innenfläche von übergeschobenen Hülsen 3, 3' aufliegen. Der Innendurchmesser der Hülsen 3, 3' ist im Vergleich zum Außendurchmesser der Rippen 2, 2' so gewählt, dass die Rippenrohre 1 , 1 ' leicht in Hülsen 3, 3' geschoben und die Rippenrohre 1 , 1 ' in Längsrichtung in den Hülsen 3, 3' gekippt werden können. Dadurch liegt die Längsachse 4, 4' des Rippenrohres 1 , 1 ' unterhalb der Längsachse 5, 5' der Hülse 3, 3'. Die Länge der Hülsen 3, 3' ist so gewählt, dass mindestens zwei Rippen 2, 70 auf der Hülse 3, 3' abgestützt sind.2, 2 rest 'on the inner surface of about pushed sleeves 3, 3'. The inner diameter of the sleeves 3, 3 'of the ribs 2, 2 is compared to the outer diameter' is so selected that the finned tubes 1, 'slightly in sleeves 3, 3' pushed 1 and the finned tubes 1, 1 'in the longitudinal direction in the sleeves 3 , 3 ' can be tilted. As a result, the longitudinal axis 4, 4 'of the finned tube 1, 1 ' lies below the longitudinal axis 5, 5 'of the sleeve 3, 3'. The length of the sleeves 3, 3 ' is selected such that at least two ribs 2, 70 are supported on the sleeve 3, 3 ' .
Fig. 2 zeigt einen Ausschnitt aus einem Rohrbündel im Querschnitt im Bereich der Hülsen 3, 3'. Es sind die in den Hülsen 3, 3' liegenden Rippenrohre 1 , 1 ' dargestellt, wobei im Bereich der Schnittlinie A-A auch die jeweilige Rippe 2, 2' eingezeichnet ist. Die Rohre 1 , 1 ' sind in horizontalen Reihen angeordnet, wobei die Mittelpunkte der Hülsen 3, 3' einer Rohrreihe jeweils im Ausmaß eines Hülsenradius gegenüber der darunterliegenden Rohrreihe versetzt sind. Dadurch liegt jede Hülse 3 mit Ausnahme der am Rand des Rohrbündels gelegenen Hülsen auf zwei Hülsen 3' der unteren Rohrreihe auf und besitzt daher je eine Berührungslinie mit insgesamt sechs anderen Hülsen 3, 3'. Die Lage dieser Berührungslinien ist bei einem in der Mitte des Rohrbündels gelegenen Hülse 3 durch strichlierte Linien angedeutet. Entlang dieser Berührungslinien werden die HülsenFig. 2 shows a section of a tube bundle in cross section in the area of the sleeves 3, 3 ' . There are shown in the sleeves 3, 3 'lying finned tubes 1, 1', wherein in the area of section line AA and the respective rib 2, 2 located '. The tubes 1, 1 ' are arranged in horizontal rows, the center points of the sleeves 3, 3 ' of a row of tubes being offset in each case by the extent of a sleeve radius with respect to the row of tubes below. As a result, each sleeve 3, with the exception of the sleeves located at the edge of the tube bundle, rests on two sleeves 3 'of the lower row of tubes and therefore each has a line of contact with a total of six other sleeves 3, 3 ' . The position of these lines of contact is indicated by dashed lines in a sleeve 3 located in the middle of the tube bundle. The sleeves are along these lines of contact
3, 3' miteinander verschweißt. Der gegenseitige Abstand der Rohre (1 , 1 ') ist durch die Abmessungen der Hülse (3, 3') automatisch gegeben.3, 3 ' welded together. The mutual spacing of the tubes (1, 1 ' ) is automatically given by the dimensions of the sleeve (3, 3 ' ).
Fig. 3 zeigt zwei übereinanderliegende Rohrbündel, die durch die Hülsen 3 dargestellt sind. Das untere Rohrbündel liegt auf einer Trageinrichtung auf, die als Sammler 6 ausgebildet ist, welcher von Medium in der angegebenen Pfeilrichtung durchströmt wird. Der Sammler 6 ist an mindestens zwei Hängeelementen 7, 8 befestigt, wobei das eine Hängeelement als Zuleitungsrohr 7 und das andere Hängeelement als Ableitungsrohr 8 ausgebildet ist. Die Pfeile geben die Strömungsrichtung des durchgeleiteten Mediums an. Das obere Rohrbündel ist auf einer als ungekühlter Träger 6' ausgebildeten Trageinrichtung aufgelagert, wobei der Träger 6' von den Hängeelementen 7, 8 getragen wird. Das zu kühlende Abgas strömt von unten durch die Rohrbündel, wobei die Abgastempe- ratur nach oben hin aufgrund der Abkühlung durch die Rohre abnimmt. Somit kann die Trageinrichtung des obenliegenden Rohrbündels als ungekühlter Träger 6' ausgebildet werden.Fig. 3 shows two superimposed tube bundles, which are represented by the sleeves 3. The lower tube bundle rests on a support device, which is designed as a collector 6, through which medium flows in the direction indicated by the arrow. The collector 6 is fastened to at least two hanging elements 7, 8, one hanging element being designed as a feed pipe 7 and the other hanging element being designed as a discharge pipe 8. The arrows indicate the direction of flow of the medium passed through. The upper tube bundle is supported on a support device designed as an uncooled support 6 ' , the support 6 ' being supported by the hanging elements 7, 8. The exhaust gas to be cooled flows from below through the tube bundle, the exhaust gas temperature temperature decreases due to the cooling through the pipes. The support device of the overhead tube bundle can thus be designed as an uncooled support 6 ' .

A profile carrier 6 ' , two side elements 7 ' and an element 9 form a support frame which holds the tube bundle or the sleeves 3. 3 ' together.
Im linken Teil von Fig. 4 ist die Seitenansicht der Rohrbündel im Bereich der Tragvorrichtungen bzw Hängeelemente dargestellt. Die waagrechten Linien in den Seitenelementen 7' zeigen die Lage der Mittelpunkte der einzelnen Reihen von Hülsen 3.In the left part of Fig. 4, the side view of the tube bundle is shown in the area of the support devices or hanging elements. The horizontal lines in the side elements 7 ' show the position of the center points of the individual rows of sleeves 3.
