Abstract

A device is provided for direct cooling of thick essentially horizontal wall members which are charged with different temperatures and possibly different pressures on their upper and lower sides, such as for cooling a heat exchanger tube sheet. Cooling of the wall member or component from the "cold side" is afford by closed end bores formed in the wall member which bores are open on the "cold side" and closed on the "hot side". Each closed end bore has a tube projecting from the "cold side" of the wall member and extending into the bore with its end within the bore located adjacent the closed end of the bore. The diameter of the tube is smaller than the diameter of the bore so that flow through the tube into the bore can reverse direction at the closed end and flow through the space between the tube and the bore.

Description

Die Erfindung richtet sich auf eine Einrichtung zur Kühlung dickwandiger, im wesentlichen waagerecht angeordneter Bauteile, die an den unteren und oberen Flächen von unterschiedlichen Temperaturen und ggf. unterschiedlichen DrÜkken beaufschlagt sind, insbesondere zur Kühlung der Rohrböden von Wärmetauschern.The invention relates to a device for cooling thick-walled, essentially horizontally arranged components which are subjected to different temperatures and possibly different pressures on the lower and upper surfaces, in particular for cooling the tube sheets of heat exchangers.

Z.B. Rohrböden von Wärmetauschern zwischen EH3-Konverter verlassendem Kreislaufgas und Wasser sind in der Regel sehr unterschiedlichen Beanspruchungen auf der Kaltseite einerseits und Warmseite andererseits ausgesetzt, so daß schon Vorschläge gemacht worden sind, diese Beanspruchungen dadurch zu reduzieren, daß entweder die beidseitigen Temperaturunterschiede geringer werden oder aber besondere Baumaßnahmen vorgenommen werden, um die Beanspruchungen durch die aggressiven Medien zu reduzieren. Zum Temperaturausgleich beschreibt z.B. die DE-OS 30 22 480 der Anmelderin eine spezielle Kreislaufgasführung. Bei dieser bekannten Lösung werden sehr gute Ergebnisse insbesondere auf dem speziellen Einsatzgebiet erreicht.For example, tube sheets of heat exchangers between the circulating gas and water leaving the EH 3 converter are generally exposed to very different stresses on the cold side on the one hand and hot side on the other, so that proposals have already been made to reduce these stresses by either reducing the temperature differences on both sides or special construction measures can be carried out to reduce the stress caused by the aggressive media. For temperature compensation, for example, DE-OS 30 22 480 of the applicant describes a special recycle gas system. With this known solution, very good results are achieved, particularly in the special field of application.

Aufgabe der Erfindung ist die Schaffung einer Lösung, mit der dickwandige, im wesentlichen waagerecht angeordnete Bauteile durch eine spezielle Gestaltung direkt gekühlt werden können, d.h. mit welcher die Temperatur der "kalten Seite" das Bauteil möglichst weit beaufschlagt.The object of the invention is to provide a solution with which thick-walled, essentially horizontally arranged components are directly cooled by a special design can be, ie with which the temperature of the "cold side" acts on the component as far as possible.

Mit einer Einrichtung der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, daß im Bauteil bzw. Rohrboden von der oberen kälteren Seite zur unteren wärmeren Seite gerichtete, verschlossene Bohrungen vorgesehen sind, und daß in jeder Bohrung ein zur kälteren Seite überstehendes, in den Fußbereich der Bohrung hineinragendes Rohr vorgesehen ist, dessen Durchmesser kleiner als derjenige der Bohrung ist.With a device of the type mentioned, this object is achieved according to the invention in that in the component or tube sheet directed from the upper colder side to the lower warmer side, sealed holes are provided, and that in each hole a protruding to the colder side, in the tube protruding into the base region of the bore is provided, the diameter of which is smaller than that of the bore.

Mit der Erfindung wird zum einen erreicht, daß durch die verschlossenen Bohrungen "die kalte" Oberfläche des Bauteiles vergrößert wird. Die in diese Bohrung hineinragenden Rohre kleineren Durchmessers ermöglichen es, wenn sich z.B. Kühlwasser auf der "kalten Seite" des Bauteiles befindet, daß dieses in die Bohrungen eingesogen und durch das nach oben zur kälteren Seite überstehende Rohr wieder ausgestoßen wird, so daß hier eine zusätzliche Kühlung erreicht wird.The invention achieves, on the one hand, that "the cold" surface of the component is enlarged by the closed bores. The smaller diameter tubes protruding into this hole make it possible, for example, if Cooling water is on the "cold side" of the component that it is sucked into the holes and ejected again through the pipe protruding upwards to the colder side, so that additional cooling is achieved here.

Die verschlossene Bohrung kann nun in unterschiedlicher Weise ausgestaltet sein. So sieht die Erfindung nach einer Gestaltung vor, daß die Länge der verschlossenen Bohrung kleiner ist als die Dicke des Bauteiles bzw. des Rohrbodens. D.h. bei der Bohrung kann es sich z.B. um eine sogenannte Sackbohrung handeln oder aber es war eine ursprünglich durchgehende Bohrung, die dann mit einem Stopfen o. dgl. wieder verschlossen wurde.The closed bore can now be designed in different ways. Thus, the invention provides for a design that the length of the closed bore is less than the thickness of the component or the tube sheet. Ie the hole can be a so-called called called blind hole or it was originally a through hole that was then closed again with a plug or the like.

Eine andere Gestaltung nach der Frfindung besteht darin, daß die verschlossene Bohrung als Durchgangsbohrung ausgebildet ist, die mit einer das Bauteil zur wärmeren Seite hin überragenden Kappe verschlossen ist. Diese letztere Gestaltung ermöglicht es, z.B. Bohrungen über die "heiße" Oberfläche des Bauteiles hinausragend zu gestalten. Befindet sich z.B. auf der heißen Seite Rauchgas, so ermöglicht die in dem Rauchgasstrom hineinragende Kappe, daß bei Wasserkühlung in der Kappe das Wasser verdampft und die Dampfblasen zur kalten Seite hin aufsteigen, so daß ein "Naturumlauf" des Kühlwassers in der verschlossenen Bohrung durch das zentrische Rohr hindurch erfolgt. Dieser Effekt wird allerdings auch bei den anderen Bohrungsgestaltungen erzielt, wenngleich er bei der letzteren Gestaltung besonders vorteilhaft auszunutzen ist.Another design according to the invention is that the closed bore is designed as a through-bore which is closed with a cap which projects beyond the component on the warmer side. This latter design enables e.g. To design holes protruding beyond the "hot" surface of the component. Is e.g. On the hot side flue gas, the cap protruding into the flue gas stream enables the water to evaporate in the cap when the water is cooled and the vapor bubbles rise to the cold side, so that a "natural circulation" of the cooling water in the closed bore through the central tube he follows. However, this effect is also achieved in the other bore designs, although it can be used particularly advantageously in the latter design.

Zur günstigeren Führung des Kühlmediums in den verschlossenen Bohrungen sieht die Erfindung in weiterer Ausgestaltung vor, daß die Bohrung im Rohrboden zur kälteren Seite hin mit einem Ring oder Steg verlängert ist und das in der Bohrung angeordnete Rohr diesen Ring überragt.For a more favorable guidance of the cooling medium in the closed bores, the invention provides in a further embodiment that the bore in the tube sheet is extended to the colder side with a ring or web and the tube arranged in the bore projects over this ring.

Eine andere Ausgestaltung der Erfindung besteht darin, daß die Ein- bzw. Austrittsöffnung des kalten bzw. erhitzten Kühlmediums am eingesetzten Rohr mit Leitelementen versehen ist. Damit kann der Eintritt des Kühlwassers gegenüber dem Austritt des aus der verschlossenen Bohrung randseitig austretenden Dampfes so gelegt werden, daß es zu einem optimalen Durchlaufen von Kühlwasser kommt.Another embodiment of the invention is that the inlet or outlet opening of the cold or heated cooling medium is provided on the tube used with guide elements. In this way, the inlet of the cooling water can be placed in relation to the outlet of the steam emerging from the edge of the closed borehole in such a way that cooling water runs through optimally.

Wie bereits eingangs angegeben, eignet sich die Erfindung insbesondere zur Kühlung von Rohrböden von Wärmetauschern.As already stated at the beginning, the invention is particularly suitable for cooling tube sheets of heat exchangers.

Die Erfindung richtet sich daher auch auf einen Rohrboden mit einer Vielzahl von Bohrungen zur Aufnahme von Wärmetauscherrohren, der sich dadurch auszeichnet, daß ein Teil dieser Bohrungen mit einer Kühleinrichtung versehen ist, mit den oben angesprochenen Merkmalen, einzeln oder in Kombination. D.h. bei einem Rohrboden kann z.B. jede vierte Bohrung als Sackbohrung, als Bohrung mit einem Verschlußstopfen oder als Durchgangsbohrung mit einer nach außen überstehenden Kappe jeweils mit dem entsprechenden in die Bohrung hineinragenden Rohr ausgerüstet sein.The invention is therefore also directed to a tube sheet with a multiplicity of bores for receiving heat exchanger tubes, which is characterized in that some of these bores are provided with a cooling device, with the features mentioned above, individually or in combination. I.e. with a tube sheet e.g. every fourth hole as a blind hole, as a hole with a sealing plug or as a through hole with an outwardly projecting cap each be equipped with the corresponding tube protruding into the hole.

Die Erfindung ist nachstehend anhand der Zeichnung beispielsweise näher erläutert. Diese zeigt in

  • Fig. 1 und 2 zwei Ausführungsbeispiele der Einrichtung an Rohrböden sowie in
  • Fig. 3 bis 5 Verteilungsbeispiele von Einrichtungen an Rohrböden.
The invention is explained below with reference to the drawing, for example. This shows in
  • 1 and 2 two embodiments of the device on tube sheets and in
  • Fig. 3 to 5 distribution examples of facilities on tube sheets.

Bezugnehmend auf Fig. 1 besteht die allgemein mit 1 be-__ zeichnete Einrichtung z.B. an einem Rohrboden 2 eines Wärmetauschers aus einer verschlossenen Bohrung 3, z.B. einer Sackbohrung, und einem in diese verschlossene Bohrung 3 hineinragenden Rohr 4, welches einen kleineren Durchmesser aufweist als die Bohrung 3 selbst. Dadurch ergibt sich ein Ringraum 5.Referring to Fig. 1, the device generally designated 1 -__ consists e.g. on a tube sheet 2 of a heat exchanger from a closed bore 3, e.g. a blind bore, and a tube 4 projecting into this closed bore 3 and having a smaller diameter than the bore 3 itself. This results in an annular space 5.

Die Bohrung 3 ist mit einem Ring bzw. Steg 6 zu der mit 7 bezeichneten kälteren Seite verlängert. Die wärmere Seite des Bauteiles 2 ist mit 8 bezeichnet.The bore 3 is extended with a ring or web 6 to the colder side designated 7. The warmer side of component 2 is designated 8.

Bei der kälteren Seite 7 kann es sich z.B. um Kühlmedium handeln, während die wärmere Seite 8 von Heißgas o. dgl. beaufschlagt sein kann bzw. von durch den Wärmetauscher hindurchgegangenges gekühltes Heißgas, welches die mit 9 bezeichneten Wärmetauscherrohre durchströmt hat.The colder side 7 can e.g. act as cooling medium, while the warmer side 8 can be acted upon by hot gas or the like or by cooled hot gas which has passed through the heat exchanger and has flowed through the heat exchanger tubes designated by 9.

Das in die Bohrung 3 hineinragende Rohr 5 überragt selbst ebenfalls zusätzlich noch den Ring 6, wie sich dies aus Fig. 1 ergibt, und ist mit einem Leitelement 10 ausgerüstet, dessen Funktion weiter unten näher beschrieben ist.The pipe 5 protruding into the bore 3 itself also additionally projects beyond the ring 6, as can be seen in FIG. 1, and is equipped with a guide element 10, the function of which is described in more detail below.

Erkennt man aus Fig. 1, daß die Länge der Bohrung 3 kürzer als die Dicke des Bauteiles 2 ist, so zeichnet sich die Ausführungsform nach Fig. 2 dadurch aus, daß die Bohrung 3' im Bauteil bzw. Rohrboden 2' als Durchgangsbohrung ausgeführt ist und mit einer Kappe 11 in die wärmere Seite 8' hineinragt.1 that the length of the bore 3 is shorter than the thickness of the component 2, the embodiment according to FIG. 2 is characterized in that the bore 3 'in the component or tube sheet 2' is designed as a through bore and protrudes into the warmer side 8 'with a cap 11.

Wie in Fig. 2 gezeigt, kann die Kappe 11 als Hülsenelement ausgebldet sein, welches eine solche Länge aufweist, daß es gleichzeitig auch den überragenden Ring 6' zur kälteren Seite 7' hin bildet. Natürlich ist die Erfindung nicht auf diese Gestaltung beschränkt. Im übrigen sind die funktionsgleichen Elemente in Fig. 2 mit den gleichen Bezugsziffern versehen, wie diejenigen Elemente der Fig. l, lediglich mit einem Strich.As shown in Fig. 2, the cap 11 can be hidden as a sleeve element which has a length such that it also forms the protruding ring 6 'towards the colder side 7'. Of course, the invention is not limited to this design. Otherwise, the functionally identical elements in FIG. 2 are provided with the same reference numerals as those elements in FIG. 1, only with a dash.

Am Beispiel der Fig. 2 sei die Funktionsweise der erfindungsgemäßen Einrichtung beschrieben:

  • Auf der kälteren Seite 7' soll sich Wasser befinden, auf der wärmeren Seite e' Ileißgas mit allerdings noch über der Verdampfungstemperatur von Wasser bei den entsprechenden Drücken liegender Gastemperatur. Das an der Kappe 11 vorbeistreichende Gas erwärmt das im Ringraum 5' befindliche Wasser derart, daß es verdampft und als Dampf den äußeren Pingraum emporsteigt. Dadurch wird in das Rohr 4' von oben, d.h. von der kalten Seite 7, das dort befindliche Wasser eingesogen, es verdampft in der Kappe 11 oder an den Wandbereichen des Rohrbodens 2- und tritt wiederum als Dampf aus. Damit ergibt sich ein "Naturumlauf" von Kühlwasser in der Einrichtung 1'. Diese Wirkungsweise ist natürlich die gleiche beim Ausführungsbeispiel nach Fig. 1. Um die Phasen Dampf/Wasser besser zu trennen, sind die Leitelemente 6 bzw. 10 vorgesehen.
The functioning of the device according to the invention is described using the example of FIG. 2:
  • On the colder side 7 'there should be water, on the warmer side e' ile gas, but with the gas temperature still above the evaporation temperature of water at the corresponding pressures. The gas flowing past the cap 11 heats the water in the annular space 5 'in such a way that it evaporates and rises as steam to the outer ping space. This will in the tube 4 'of above, ie from the cold side 7, the water located there is sucked in, it evaporates in the cap 11 or on the wall areas of the tube sheet 2 - and in turn emerges as steam. This results in a "natural circulation" of cooling water in the device 1 '. This mode of operation is of course the same in the exemplary embodiment according to FIG. 1. In order to better separate the steam / water phases, the guide elements 6 and 10 are provided.

Schließlich zeigen die Fig. 3 bis 5 noch Verteilungsbeispiele der Kühleinrichtungen 1 bzw. 1-. Hier kann ein Teil der Bohrungen 12 für die Wärmetauscherrohre 9 mit einer Einrichtung ausgerüstet sein, wie sie erfindungsgemäß gestaltet ist, d.h. entweder sind derartige Bohrungen als Sackbohrungen oder nachträglich verschlossene Bohrungen ausgebildet, wie dies in Fig. 1 dargestellt ist, oder aber entsprechend dem Ausführungsbeispiel der Fig. 2 gestaltet.Finally, FIGS. 3 to 5 show distribution examples of the cooling devices 1 and 1-, respectively. Here, part of the bores 12 for the heat exchanger tubes 9 can be equipped with a device as designed according to the invention, i.e. either such bores are designed as blind bores or subsequently closed bores, as shown in FIG. 1, or else are designed in accordance with the exemplary embodiment in FIG. 2.

Natürlich sind die beschriebenen Ausführungsbeispiele noch in vielfacher Hinsicht abzuändern, ohne den Grundgedanken der Erfindung zu verlassen. So ist die Erfindung, wie dies auch in Fig. 2 angedeutet ist, nicht auf eine besondere Gestaltung des zu kühlenden Bauteiles beschränkt. Hier können Beschichtungen gegen aggressive Medien ebenso vorgesehen sein, wie besondere Rohrgestaltungen der heißgasführenden Kühlrohre. Die in dem Raum 8 des in der Regel aggressiven zu kühlenden Gases hineinragenden Kappen 11 können besonders beschichtet sein. Sackbohrungen gemäß Fg. 1 können mit solchen Gestaltungen wechseln, wie sie in Fig. 2 dargestellt sind u. dgl. mehr. Dies trifft auch für die besondere dargestellte Gestaltung der Dampf- bzw. Wasserleitelemente zu. Diese können auch andere Gestaltungen haben, wesentlich ist lediglich, daß gewährleistet ist, daß das eintretende Kühlwasser nicht vom austretenden Wasserdampf am Eintritt gehindert wird.Of course, the exemplary embodiments described can still be modified in many ways without departing from the basic idea of the invention. Thus, as is also indicated in FIG. 2, the invention is not restricted to a special design of the component to be cooled. Coatings against aggressive media can also be provided here, as can special pipe designs of the hot gas-carrying cooling pipes. The caps 11 protruding into the space 8 of the gas, which is generally aggressive to be cooled be specially coated. 1 can change with such designs, as shown in Fig. 2 u. Like. more. This also applies to the special design of the steam or water guiding elements shown. These can also have other designs, the only essential thing is that it is ensured that the entering cooling water is not prevented from entering by the emerging water vapor.
