Description

Die Erfindung betrifft eine Anordnung zur Rückkühlung von Kühlwasser gemäß den Merkmalen im Oberbegriff des Anspruchs 1.The invention relates to an arrangement for the recooling of cooling water according to the features in the preamble of claim 1.

Eine solche Anordnung weist von horizontalen Riegeln getragene, von dem eine Temperatur zwischen etwa 20°C und 60°C aufweisenden Kühlwasser beaufschlagte Verteilerrohre mit abwärts gerichteten Sprühdüsen und Tropfenabscheider auf. Die Verteilerrohre bilden zusammen mit den oberhalb der Verteilerrohre vorgesehenen Tropfenabscheidern und unterhalb der Verteilerrohre angeordneten Rieseleinbauten in Form von zum Beispiel dünnwandigen Lamellen oder Gittern Bestandteil einer Rückkühleinheit in einem Nass- oder Hybridkühlturm, wobei das über die Sprühdüsen aus den Verteilerrohren tretende Kühlwasser sich möglichst dünnschichtig auf den Rieseleinbauten verteilt, welche mit natürlichem Luftzug oder Zwangsbelüftung mittels zum Beispiel Ventilatoren beaufschlagt werden. Das von den Rieseleinbauten herabfallende und von der Luft rückgekühlte Kühlwasser wird bodenseitig des Kühlturms gesammelt und anschließend seiner kühlenden Aufgabe wieder zugeführt. Die oberhalb der Verteilerrohre befindlichen Tropfenabscheider haben die Aufgabe, Wassertropfen aus nach oben strömendem Wasserdampf abzuscheiden, so dass der Schwadenaustrag an einer Kühlturmkrone minimiert wird.Such an arrangement has manifolds supported by horizontal bars and acted upon by cooling water having a temperature of between about 20 ° C and 60 ° C with downwardly directed spray nozzles and mist eliminators. The distribution pipes, together with the above the distribution pipes provided dropletizers and arranged below the distribution pipes Rieseleinbauten in the form of, for example, thin-walled lamellae or grids part of a recooling unit in a wet or hybrid cooling tower, wherein the over the spray nozzles from the distribution pipes passing cooling water as thin as possible the Rieseleinbauten distributed, which are acted upon by natural draft or forced ventilation means, for example, fans. The cooling water falling from the Rieseleinbauten and cooled by the air is collected on the bottom side of the cooling tower and then fed back to its cooling task. The located above the distribution pipes Mist eliminators have the task of separating water droplets from water vapor flowing upwards, so that the discharge of steam at a cooling tower crown is minimized.

Das Traggerüst für die Rieseleinbauten, die Verteilerrohre und die Tropfenabscheider wird in der Regel aus vertikalen Ständern und horizontalen Riegeln gebildet. Die Ständer und Riegel können aus Beton, faserverstärkten Kunststoffen, insbesondere glasfaserverstärkten Kunststoffen (GFK) oder Holz bestehen. Stahlkonstruktionen sind möglich. Während die aus mehreren Flächensegmenten gebildeten Tropfenabscheider unmittelbar auf den Riegeln angeordnet werden, befinden sich die Verteilerrohre unterhalb der Riegel. Bei der Montage der Verteilerrohre ist es somit notwendig, sie mittels geeigneter Hebezeuge nach unterhalb der Riegel zu verlagern und dann an diesen mit Spannbändern oder Schellen zu befestigen. Im Hinblick auf die Querschnittsabmessungen eines Kühlturms und darauf, dass die Verteilerrohre über mehrere Abhängungspunkte gehalten werden, ist ein erheblicher Montageaufwand erforderlich. Außerdem können die Verteilerrohre nur nacheinander eingebracht werden, da sie eine begrenzte Länge haben und daher eine Vielzahl von Kuppelstellen vorgesehen werden müssen. Beim Kuppeln müssen die hängend montierten Verteilerrohre auch noch horizontal verschoben werden.The support framework for the trickle installations, the distribution pipes and the droplet separators is usually formed of vertical uprights and horizontal bars. The stands and bars may consist of concrete, fiber-reinforced plastics, in particular glass fiber reinforced plastics (GRP) or wood. Steel structures are possible. While the droplets formed from several surface segments are placed directly on the bars, the manifolds are below the bars. When mounting the distribution pipes, it is therefore necessary to move them by means of suitable lifting equipment below the bolt and then attach to this with straps or clamps. In view of the cross-sectional dimensions of a cooling tower and that the distribution pipes are held over several suspension points, a considerable installation effort is required. In addition, the manifolds can be introduced only one after the other, since they have a limited length and therefore a plurality of coupling points must be provided. When coupling, the hanging mounted distribution pipes must also be moved horizontally.

Die mehrlagig ausgebildeten Rieseleinbauten unterhalb der mit den Sprühdüsen versehenen Verteilerrohre werden mittels insbesondere glasfaserverstärkten Kunststoffträgern und entsprechenden Aufhängemitteln, welche ebenfalls an den Riegeln befestigt werden, lageorientiert.The multilayer Rieseleinbauten below the distribution nozzles provided with the spray nozzles are by means of particular glass fiber reinforced plastic carriers and corresponding suspension means, which are also attached to the bars, position-oriented.

Sind Reparaturarbeiten an den Verteilerrohren erforderlich, können sie aufgrund der Rieseleinbauten nur von oben demontiert und anschließend wieder montiert werden. Man muss sie hierbei zunächst provisorisch fixieren, um danach unter Aufhebung der Fixierungen die einzelnen Verteilerrohre zwischen den Riegeln hindurch nach oben zu entfernen. Es ist deshalb erforderlich, die Verteilerrohre entsprechend kurz zu halten, wodurch der Demontage- und Montagaufwand im Hinblick die Kupplungen zwischen zwei Verteilerrohren noch weiter erhöht wird.If repair work on the distribution pipes is required, they can only be disassembled from above and then re-assembled due to the trickle installations. First of all, you have to provisionally fix them in order to then remove the individual distribution tubes between the transoms by lifting the fixations upwards. It is therefore necessary to keep the manifolds short accordingly, causing the Disassembly and assembly costs in terms of the clutches between two manifolds is further increased.

Bekannt ist es ferner, die Verteilerrohre durch Löcher in den Riegeln zu schieben und miteinander zu koppeln. Dies bedeutet, dass vergleichsweise kurze Verteilerrohre zum Einsatz gelangen, die entsprechend viele Kuppelstellen aufweisen müssen. Auch dies ist montage- und kostenaufwendig. Solche Riegel werden zumeist aus Beton gebildet.It is also known to push the distribution pipes through holes in the bars and to couple with each other. This means that relatively short distribution pipes are used, which must have a corresponding number of coupling points. Again, this is easy to install and expensive. Such bars are usually made of concrete.

Zum Stand der Technik ist die US 4 543 218 A zu nennen, die eine Anordnung zur Rückkühlung von Kühlwasser offenbart, welche von horizontalen Riegeln getragene Verteilerrohre mit Sprühdüsen und Tropfenabscheidern aufweist. Die Riegel sind mit nach oben offenen Lagerstellen zur Eingliederung der Verteilerrohre versehen. Eine solche Anordnung ist auch aus der GB 1 566 922 A bekannt.The state of the art is the US 4,543,218 A to be mentioned, which discloses an arrangement for the re-cooling of cooling water, which has supported by horizontal bars distribution pipes with spray nozzles and droplet separators. The bars are provided with upwardly open bearings for the integration of the distribution pipes. Such an arrangement is also from the GB 1 566 922 A known.

Die EP 0 437 133 A und die Veröffentlichung "PRADON D: "ECONOMIE D 'ENERGIE: UN NOUVEAU TYPE DE REFRIGERANT SCAM" TECHNIQUES CEM, PARIS, FR, Nr. 117, 1. November 1983 (1983-11-01), Seiten 36 - 45, offenbaren ebenfalls Riegel, auf welchen die Tropfenabscheider liegen.The EP 0 437 133 A and the publication "PRADON D:" ECONOMY D 'ENERGY: UN NOUVEAU TYPE DE REFRIGERANT SCAM "TECHNIQUES CEM, PARIS, FR, No. 117, November 1, 1983 (1983-11-01), pages 36-45, also disclose bars on which the mist eliminators lie.

Der Erfindung liegt die Aufgabe zu Grunde, eine Anordnung zur Rückkühlung von Kühlwasser zu schaffen, welche eine einfachere Montage der Verteilerrohre gewährleistet sowie den Aufwand bei späteren Reparaturen der Verteilerrohre deutlich herabsetzt.The invention is based on the object to provide an arrangement for re-cooling of cooling water, which ensures a simpler installation of the manifolds and significantly reduces the cost of subsequent repairs of the manifolds.

Die Lösung dieser Aufgabe besteht nach der Erfindung in den Merkmalen des Anspruchs 1.The solution to this problem consists according to the invention in the features of claim 1.

Dementsprechend sind nunmehr die Riegel mit nach oben offenen, sich vorzugsweise über ihre gesamte Breite erstreckenden Lagerstellen zur Eingliederung der Verteilerrohre versehen. Zwei in Längsrichtung der Riegel aufeinander folgende Lagerstellen sind mittels einer Stütze für die Tropfenabscheider voneinander getrennt.Accordingly, now the bars are provided with upwardly open, preferably extending over its entire width bearing points for incorporation of the manifolds. Two consecutive in the longitudinal direction of the bolt bearings are separated by means of a support for the mist eliminator.

Die Erfindung ermöglicht es folglich, dass die Verteilerrohre auch in größerer Anzahl problemlos von oben in die Lagerstellen eingegliedert werden können. Das Kuppeln der Verteilerrohre kann erfolgen, wenn sich die Verteilerrohre in den Lagerstellen befinden. Besondere Hilfsmittel zum Verlegen der Verteilerrohre sind nicht mehr erforderlich, da diese liegend und nicht hängend angeordnet sind.The invention thus makes it possible that the distribution pipes can be easily incorporated from above into the bearings in larger numbers. The coupling of the distribution pipes can take place when the distribution pipes are located in the bearings. Special tools for laying the distribution pipes are no longer necessary because they are horizontal and not hanging.

Nachdem alle Verteilerrohre verlegt und miteinander gekuppelt sind, können die Tropfenabscheider auf die Stützen gelegt und ordnungsgemäß fixiert werden.After all distribution pipes have been laid and coupled with each other, the droplet separators can be placed on the supports and fixed properly.

Müssen Verteilerrohre repariert werden, ist es lediglich erforderlich, die Flächensegmente der Tropfenabscheider in den entsprechenden Bereichen zu entfernen. Die Verteilerrohre liegen dann frei in den nach oben offenen Lagerstellen. Sie können anschließend ohne Weiteres nach oben entfernt und gegen neue Verteilerrohre ausgetauscht werden.If distribution pipes have to be repaired, it is only necessary to remove the surface segments of the droplet separators in the corresponding areas. The distribution pipes are then free in the upwardly open bearings. They can then be easily removed upwards and replaced with new distribution pipes.

Gemäß den Merkmalen des Anspruchs 2 bilden die Stützen einstückige Bestandteile der Riegel. Dies ist unabhängig von Werkstoffen möglich (Beton, faserverstärktem Kunststoff, Holz, Faserzement, Stahl).According to the features of claim 2, the supports form integral parts of the bolt. This is possible regardless of material (concrete, fiber-reinforced plastic, wood, fiber cement, steel).

Vorstellbar ist es entsprechend Anspruch 3 aber auch, dass die Stützen mit den Riegeln koppelbar sind. Das heißt, die Stützen und die Riegel werden getrennt hergestellt und lösbar oder unlösbar so miteinander verbunden, dass die Lagerstellen entstehen.It is conceivable according to claim 3 but also that the supports can be coupled with the bars. That is, the supports and the bars are made separately and releasably or permanently connected together so that the bearings arise.

Erfindungsgemäß ist es ferner von Vorteil, wenn entsprechend den Merkmalen des Anspruchs 4 kopfseitig der Stützen sich in Längsrichtung der Riegel erstreckende taschenartige Aufnahmen für die Tropfenabscheider tragende Leisten vorgesehen sind. Danach werden die Tropfenabscheider nicht unmittelbar auf die Stützen, sondern auf die sich kopfseitig der Stützen erstreckenden Leisten gelegt. Die Aufnahmen kopfseitig der Stützen sorgen dafür, dass die Leisten eine einwandfreie seitliche Führung haben. Die Leisten für die Aufnahme der Tropfenabscheider können auch Bestandteil der Tropfenabscheider selbst sein. Dabei wird an den Tropfenabscheiderpaketen quasi kopf- oder stirnseitig eine Halteleiste angebracht, die dann zur Längsunterstützung der Tropfenabscheider oberhalb der Riegel dient.According to the invention it is also advantageous if according to the features of claim 4 head-side of the supports are provided in the longitudinal direction of the latch extending pocket-like receptacles for the droplets carrying strips. Thereafter, the droplet are not placed directly on the supports, but on the head-side of the supports extending strips. The recordings on the head of the supports ensure that the strips have a perfect lateral guidance. The strips for receiving the droplet separators may also be part of the droplet separator itself. It is the mist eliminator packages quasi head or front side attached to a retaining strip, which then serves for longitudinal support of the mist eliminator above the bars.

Die Leisten können aus Kunststoff, insbesondere aus einem faserverstärktem Kunststoff, insbesondere GFK, Holz, Faserzement oder Stahl bestehen. Der Querschnitt ist zweckmäßig so gestaltet, dass an beiden Längsrändern der ansonsten als Flachleisten ausgebildeten Leisten sich nach oben erstreckende konvexe Längswulste vorgesehen sind, welche die Tropfenabscheider tragen.The strips may be made of plastic, in particular of a fiber-reinforced plastic, in particular GRP, wood, fiber cement or steel. The cross section is expediently designed so that upwardly extending convex longitudinal beads are provided on both longitudinal edges of the strips otherwise formed as flat strips, which carry the droplet separators.

Mit Rücksicht auf den Sachverhalt, dass die Verteilerrohre in den Lagerstellen der Riegel liegen, ist es zur Verkürzung des Abstands zwischen den Sprühdüsen und den Rieseleinbauten nach Anspruch 5 vorgesehen, dass die Sprühdüsen mittels sich vertikal erstreckender Überbrückungsrohre zu den Verteilerrohren distanziert sind. Die Überbrückungsrohre haben dann eine Länge, die etwa der vertikalen Dicke der Riegel unterhalb der Lagerstellen entspricht.With regard to the fact that the distribution pipes lie in the bearing points of the bars, it is provided to shorten the distance between the spray nozzles and the Rieseleinbauten claim 5 that the spray nozzles are spaced by means of vertically extending bridging pipes to the distribution pipes. The bridging pipes then have a length that corresponds approximately to the vertical thickness of the bolt below the bearings.

Hiervon sind die Riegel 3, wie auch die Figuren 2 und 3 erkennen lassen, mit nach oben offenen, sich über ihre gesamte Breite B erstreckenden Lagerstellen 5 zur Eingliederung von Verteilerrohren 6 für rückzukühlendes Kühlwasser versehen. Jeweils zwei in Längsrichtung der Riegel 3 aufeinander folgende Lagerstellen 5 sind mittels einer Stütze 7 für oberhalb der Verteilerrohre 6 vorgesehene Tropfenabscheider 8 voneinander getrennt. Die Tropfenabscheider 8 bestehen aus in der Vertikalen gekrümmten Kunststofflamellen und sind in mehrere Flächensegmente 9 gegliedert. In Figur 1 handelt es sich um eine Explosionsdarstellung, bei welcher die Tropfenabscheider 8 in Abstand zu den Stützen 7 dargestellt sind. Die unterbrochenen Linien deuten an, dass sich ein Flächensegment 9 immer von Riegel 3 zu Riegel 3 erstreckt. Die Stützen 7 können einstückige Bestandteile der Riegel 3 bilden (Figur 1) oder mit den Riegeln 3 lösbar oder unlösbar verbunden sein (Figur 2).The arrangement 1 comprises a plurality of vertical uprights 2 as well as longitudinal bars 3, 4 extending in the longitudinal and transverse directions. Of these, the bars 3, as well as the FIGS. 2 and 3 let recognize, with upwardly open, over its entire width B extending bearings 5 for incorporation of distribution pipes 6 provided for rückzukühlendes cooling water. In each case two successive bearing points 5 in the longitudinal direction of the bolt 3 are separated from each other by means of a support 7 for above the distributor pipes 6 provided droplet separator 8. The droplet 8 consist of curved in the vertical plastic lamellae and are divided into several surface segments 9. In FIG. 1 it is an exploded view, in which the droplet 8 are shown at a distance from the supports 7. The broken lines indicate that a surface segment 9 always extends from bar 3 to bar 3. The supports 7 can form integral parts of the bolt 3 ( FIG. 1 ) or be connected to the bars 3 detachably or permanently ( FIG. 2 ).

Wie die Figuren 2 und 3 näher zu erkennen geben, sind kopfseitig der Stützen 7 sich in Längsrichtung der Riegel 3 erstreckende taschenartige Aufnahmen 10 für die Tropfenabscheider 8 tragende Leisten 11 vorgesehen. Die Leisten 11 bestehen in diesem Ausführungsbeispiel aus Kunststoff. Sie sind überwiegend als Flachleisten ausgebildet und besitzen an den Längsrändern nach oben abstehende konvexe Wulste 12, auf welche die Enden der Flächensegmente 9 der Tropfenabscheider 8 gelegt werden.As the FIGS. 2 and 3 give more detail, head-side of the supports 7 are in the longitudinal direction of the latch 3 extending pocket-like receptacles 10 for the droplet 8 carrying strips 11 is provided. The strips 11 are made in this embodiment of plastic.
