Description

Die Erfindung betrifft einen Einbau für einen Kühlturm sowie einen Kühlturm, in dem mehrere Einbauten hängend angeordnet sind.The invention relates to an installation for a cooling tower and a cooling tower, in which several installations are arranged hanging.

Die Kühlung von tropfenförmigen ("rieselnden") Medien im Gegenstrom in einem Kühlturm (Rieselkühlung) ist grundsätzlich bekannt. Hierzu werden Einbauten verwendet, die als Pakete bzw. Stapel aus gewellten Kunststofflagen ausgebildet sind. Benachbarte Kunststofflagen sind mit ihren Wellungen winklig zueinander angeordnet zu einem Stapel zusammengesetzt, wobei die so hergestellten Einbauten derart in den Kühlturm eingebaut werden, dass das von oben in den Kühlturm eingebrachte zu kühlende Medium (beispielsweise Wasser) in die Kanäle zwischen benachbarte Kunststofflagen der Stapel gelangt und von unten durch diese Kanäle Luft nach oben strömt, Mit anderen Worten sind die Einbauten also im Kühlturm derart ausgerichtet, dass ihre einzelnen Kunststofflagen vertikal verlaufen.The cooling of drop-shaped ("trickling") media in countercurrent in a cooling tower (trickle cooling) is basically known. For this purpose, internals are used, which are formed as packages or stacks of corrugated plastic layers. Adjacent plastic layers are arranged with their corrugations arranged at an angle to one another to form a stack, the internals produced in this way being installed in the cooling tower such that the medium to be cooled (for example water) introduced from above into the cooling tower enters the channels between adjacent plastic layers of the stacks and from below through these channels air flows upwards, In other words, the internals are thus aligned in the cooling tower so that their individual plastic layers are vertical.

Beispiele für derartige Einbauten finden sich beispielsweise in DE-A-42 41 859 , DE-C-197 33 480 , DE-C-198 19 945 und DE-B-103 25 723 .Examples of such installations can be found for example in DE-A-42 41 859 . DE-C-197 33 480 . DE-C-198 19 945 and DE-B-103 25 723 ,

Die zuvor beschriebenen Einbauten werden innerhalb der Kühltürme übereinanderliegend untergebracht, wobei die gesamte Anordnung auf einer Stützkonstruktion des Kühlturms ruht, wie es beispielhaft in DE-A-10 2005 010 462 beschrieben ist. Durch die Stützkonstruktion verteuert sich die Montage und erhöht sich der konstruktive Aufwand, was nachteilig ist. Aus EP-A-1 703 041 ist es bekannt, übereinander gestapelte Gittermattenstapel hängend in einen Rieselkühler anzuordnen.The internals described above are housed one above the other within the cooling towers, the entire assembly resting on a support structure of the cooling tower, as exemplified in US Pat DE-A-10 2005 010 462 is described. Due to the support structure increases the cost of assembly and increases the design effort, which is disadvantageous. Out EP-A-1 703 041 It is known to arrange stacked grid mesh stack hanging in a trickle cooler.

Aufgabe der Erfindung ist es, einen Einbau für einen Kühiturm zu schaffen, dessen Unterbringung im Kühlturm vereinfacht ist.The object of the invention is to provide an installation for a Kühiturm whose housing is simplified in the cooling tower.

Zur Lösung dieser Aufgabe wird mit der Erfindung ein Einbau für einen Kühlturm vorgeschlagen, der versehen ist mit

  • einer Vielzahl von gewellten Kunststoff-Gittermatten, die zur Bildung eines Pakets aneinander liegen, wobei jede Gittermatte mindestens ein erstes und ein zweites Durchgangsloch aufweist und wobei die ersten Durchgangslöcher sowie die zweiten Durchgangslöcher sämtlicher Gittermatten des Pakets jeweils zumindest bereichsweise miteinander fluchten,
  • zwei strangförmigen Durchdringungselementen, die sich durch die ersten bzw. zweiten Durchgangslöcher der Gittermatten hindurch erstrecken, wobei die beiden einander abgewandten Enden der Durchdringungselemente beidseitig des Pakets überstehen, und
  • Aufhängungselementen, die mit den überstehenden Enden der Durchdringungselemente zur herabhängenden Anordnung des Pakets in einem Kühlturm in Eingriff bringbar sind.
To solve this problem, an installation for a cooling tower is proposed with the invention, which is provided with
  • a plurality of corrugated plastic mesh mats adjacent each other to form a package, each mesh mat having at least first and second through holes, and wherein the first through holes and the second through holes of all the mesh mats of the package are at least partially aligned with each other,
  • two strand-like penetrating members extending through the first and second through holes of the grid meshes, respectively, the two opposite ends of the penetrating members projecting on both sides of the packet, and
  • Suspension members engageable with the projecting ends of the penetrating members for suspending the package in a cooling tower.

Erfindungsgemäß ist vorgesehen, die an sich bekannten Kunststoff-Gittermatten-Pakete nicht mehr auf einer Stützkonstruktion innerhalb eines Kühlturms übereinander aufliegend sondern von oben herabhängend im Kühlturm anzuordnen. Hierzu sind die Pakete von Durchdringungselementen (Stangen o.dgl.) durchzogen, deren Enden beidseitig der Pakete aus diesen herausragen und damit geeignet sind, über Aufhängungselemente im Turm aufgehängt zu werden. In dieser Position befindet sich dann jedes Paket in seiner Einbau- und Funktionslage, in der es von sich kreuzenden Kanälen in vertikaler Richtung durchzogen wird. Diese Kanäle entstehen durch die gewellten Kunststoff-Gittermatten, wobei ein Medienaustausch von Kanal zu Kanal auf Grund der Gitterstruktur der Kunststoffmatten möglich ist.According to the invention, it is no longer arranged on a support structure within a cooling tower superimposed but to hang from above in the cooling tower the known per se plastic mesh mats packages. For this purpose, the packages are penetrated by penetrating elements (rods or the like), the ends of which protrude on both sides of the packages from these and are thus suitable to be suspended via suspension elements in the tower. In this position, each package is then in its installation and functional position, in which it is crossed by intersecting channels in the vertical direction. These channels are created by the corrugated plastic mesh mats, with a media exchange from channel to channel due to the lattice structure of the plastic mats is possible.

Durch die erfindungsgemäß vorgesehene hängende Anordnung eines Kunststoff-Gittermatten-Pakets entfällt die Stützkonstruktion im Kühlturm, wie sie gegenwärtig bei den bekannten Konzepten erforderlich ist.The inventively provided suspended arrangement of a plastic grid mesh package eliminates the support structure in the cooling tower, as currently required in the known concepts.

Als strangförmige Durchdringungselemente bieten sich in vorteilhafter Weiterbildung der Erfindung grundsätzlich sämtliche Profil- o.dgl. Stangenelemente an. Diese können im Querschnitt kreisrund oder aber auch mehreckig sein.As strand-like penetrating elements, in an advantageous development of the invention, basically all profile or the like are available. Rod elements. These may be circular in cross-section or else polygonal.

Die Durchgangslöcher in den Gittermatten weisen eine Form auf, die es erlaubt, dass sie die Durchdringungselemente aufnehmen. Auf Grund von Toleranzen o,dgl, Fertigungsungenauigkeiten sollten die Durchgangslöcher eine Form und Größe aufweisen, die es erlaubt, dass die Durchgangslöcher der Gittermatten eines Pakets zumindest bereichsweise in einem Ausmaß miteinander fluchten, dass ein "Durchgangskanal" entsteht, der geeignet ist, das Durchdringungselement aufzunehmen. Hier ist es zweckmäßig, wenn sich die ersten und zweiten Durchgangslöcher in Richtung der herstellungstechnisch größten zu erwartenden Fertigungsabweichungen erstrecken, und zwar in einem größeren Ausmaß als die Querschnittsform der Durchdringungselemente, Insbesondere ist es von Vorteil, wenn die Durchgangslöcher bzw. zumindest die ersten oder die zweiten Durchgangslöcher als Langlöcher ausgebildet sind.The through holes in the grid mats have a shape that allows them to receive the penetrating elements. Due to tolerances of manufacturing inaccuracies, the through-holes should have a shape and size that allow the through-holes of the lattice mats of a package to be at least partially aligned with one another to an extent that creates a "through-channel" suitable for the penetrating element take. Here, it is expedient for the first and second through holes to extend in the direction of the production-related greatest expected production deviations, to a greater extent than the cross-sectional shape of the penetrating elements. In particular, it is advantageous if the through-holes or at least the first or the second through-holes second through holes are formed as slots.

In vorteilhafter Weiterbildung der Erfindung ist vorgesehen, dass die ersten Durchgangslöcher jeweils eine Form aufweisen, die im wesentlichen gleich der Querschnittskontur der Durchdringungselemente sind, und dass die zweiten Durchgangslöcher eine Form aufweisen, die in Richtung einer beide Durchgangslöcher einer Gittermatte verbindenden gedachten Linie eine größere Erstreckung aufweist als die Querschnittskontur des Durchdringungselements in Richtung der gedachten LinieIn an advantageous embodiment of the invention it is provided that the first through-holes each have a shape which are substantially equal to the cross-sectional contour of the penetrating elements, and that the second through-holes have a shape which, in the direction of an imaginary line connecting both through-holes of a grid mat, has a greater extent has as the cross-sectional contour of the penetrating element in the direction of the imaginary line

Als Aufhängungselemente bieten sich Seile, Drähte oder Ketten an, die insbesondere als Schlaufen ausgebildet sind, so dass in die Aufhängungselemente die Enden der Durchdringungselemente einhängbar sind. Die Aufhängung der Aufhängungselemente am Kühlturm erfolgt zweckmäßigerweise durch eine entsprechende einzelne Quertraverse o,dgl, Verstrebungen aufweisende Konstruktion bzw. durch Haken.As suspension elements, ropes, wires or chains offer, which are designed in particular as loops, so that in the suspension elements, the ends of the penetrating elements are suspended. The suspension of the suspension elements on the cooling tower is advantageously carried out by a corresponding individual cross-beam o, the like, struts having construction or by hooks.

Damit die einzelnen Pakete nicht unbeabsichtigt auseinanderfallen können, ist bei einem weiteren vorteilhaften Ausführungsbeispiel der Erfindung vorgesehen, dass die Pakete von Zugankerelementen durchdrungen sind und/oder dass jeweils benachbarte Gittermatten der Pakete kraftschlüssig (beispielsweise durch Zapfen-Loch-Verbindungen) miteinander gekoppelt sind.So that the individual packages can not unintentionally fall apart, in a further advantageous embodiment of the invention it is provided that the packages are penetrated by tie rod elements and / or that adjacent grid mats of the packages are non-positively coupled (for example by pin-hole connections).

Mit dem erfindungsgemäßen Konzept ist es möglich, die Pakete innerhalb verschiedener untereinanderliegender Ebenen im Kühlturm jeweils von oben herabhängend anzuordnen. Hierbei können sich sämtliche Aufhängungselemente ausgehend von einer gemeinsamen "Aufhängungsebene" im oberen Bereich des Kühlturms bis in Höhe der einzelnen Paket-Ebenen erstrecken. Alternativ ist es möglich, dass die in unterschiedlichen Ebenen übereinander angeordneten Pakete durch Aufhängungselemente aneinanderhängen, wobei nur die Pakete in der obersten Ebene ihrerseits über Aufhängungselemente von der "Aufhängungsebene" herabhängend angeordnet sind.With the concept according to the invention, it is possible to arrange the packages within different levels lying in the cooling tower in each case hanging from above. Here, all suspension elements can extend from a common "suspension level" in the upper region of the cooling tower up to the level of the individual package levels. Alternatively, it is possible for the packets stacked on different levels to be suspended from one another by suspension elements, with only the top-level parcels in turn being suspended above suspension elements from the "suspension plane".

Schließlich ist aber auch eine Anordnung der hängenden Einbauten möglich, bei der zumindest einige der Einbauten genutzt werden, um auf ihnen aufliegende Einbauten zu platzieren. Damit entstehen Stapel von mindestens zwei übereinander angeordneten und aufeinanderliegenden Paketen, wobei das unterste Paket an seinen Aufhängungselementen hängt und damit die anderen Pakete trägt.Finally, however, an arrangement of the suspended internals is possible in which at least some of the fixtures are used to place placed on them internals. This creates stacks of at least two superimposed and stacked packages, the lowest package hangs on its suspension elements and thus carries the other packages.

In weiterer vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass die strangförmigen Durchdringungselemente an ihren Enden Vorsprünge o.dgl. aufweisen, die ein Abrutschen der schlaufenförmigen Aufhängungselemente verhindern. Hierbei kann es sich beispielsweise um auf die Enden der Durchdringungselemente aufgesetzte oder auf andere Art und Weise angebrachte Scheiben, Stifte, Bolzen o.dgl. handeln. Auch auf die Enden aufgesetzte Hülsen mit Außenflanschen sind denkbar.In a further advantageous embodiment of the invention it is provided that the strand-shaped penetrating elements at their ends projections or the like. have, which prevent slipping of the loop-shaped suspension elements. This may, for example, to the ends of the penetrating elements patch or otherwise attached discs, pins, bolts or the like. act. Also on the ends patch sleeves with outer flanges are conceivable.

The invention will be explained in more detail with reference to several embodiments and with reference to the drawings. In detail, they show:

Fig. 1 zeigt perspektivisch einen Einbau 10 für einen Kühlturm, wobei der Einbau 10 ein Paket 12 aus mehreren im Gebrauchszustand vertikal angeordneten gewellten Gittermatten 16 aufweist. Benachbarte Gittermatten 16 weisen sich kreuzende Wellungen auf. Hierdurch entstehen in dem Paket 12 sich kreuzende Kanäle, wie es an sich bei Gittereinbauten für Kühltürme bekannt ist. Fig. 1 shows in perspective an installation 10 for a cooling tower, wherein the installation 10 has a package 12 of a plurality of vertically disposed in use wavy grid mats 16. Adjacent grid mats 16 have intersecting corrugations. As a result, in the package 12 intersecting channels, as is known in lattice installations for cooling towers.

Das Paket 12 ist durch zwei Zugankerelemente 18 gegen ein unbeabsichtigtes Auseinanderfallen gesichert. Zusätzlich können benachbarte Gittermatten 16 durch Zapfen-Loch-Verbindungen kraftschlüssig aneinander gekoppelt sein.The package 12 is secured by two tie rod elements 18 against accidental falling apart. In addition, adjacent grid mats 16 may be frictionally coupled to each other by pin-hole connections.

Die Besonderheit des Pakets 12 gemäß Fig. 1 besteht in zwei strangförmigen Durchdringungselementen 20, die in diesem Ausführungsbeispiel als Rohre (vorzugsweiseaus VA-Stahl) ausgebildet sind. Alternativ können auch Vollmaterial-Durchdringungselemente sowie Durchdringungselemente mit anderen als kreisförmigen runden Querschnittsflächen verwendet werden.The peculiarity of the package 12 according to Fig. 1 consists of two strand-shaped penetrating elements 20, which are formed in this embodiment as tubes (preferably made of VA steel). Alternatively, solid-material penetrating elements as well as penetrating elements with other than circular round cross-sectional areas can also be used.

Die beiden strangförmigen Durchdringungselemente 20 ragen mit ihren Enden 22 beidseitig aus dem Paket 12 heraus. Sie erstrecken sich ferner durch erste bzw. zweite Durchgangslöcher 23,24, die beide bzw. von denen mindestens eines als Langloch ausgebildet sein sollten bzw. sollte. Entscheidend ist, dass die Durchgangslöcher eine Größe und Form aufweisen, so dass im montierten Zustand des Pakets 12 sich durch diesen hindurch Durchgangskanäle zur Aufnahme der Durchdringungselemente 20 bilden.The two strand-shaped penetration elements 20 protrude with their ends 22 on both sides of the package 12 out. They also extend through first and second through holes 23,24, both of which should be or at least should be designed as a slot. It is crucial that the through-holes have a size and shape, so that in the mounted state of the package 12 pass through channels for receiving the penetrating elements 20 form.

An den Enden 22 der Durchdringungselemente 20 befinden sich abstehende, umlaufende Sicherungsvorsprünge in Form von Flanschen 25, die in diesem Ausführungsbeispiel als Scheibenkörper ausgebildet sind und gegen ein Ablösen an den Durchdringungselementen 20 gesichert sind.At the ends 22 of the penetration elements 20 are projecting, circumferential securing projections in the form of flanges 25, which are formed in this embodiment as a disk body and secured against detachment at the penetration elements 20.

Die strangförmigen Durchdringungselemente 20 eignen sich nun dazu, mehrere Pakete 12 innerhalb eines Kühlturms so, wie beispielhaft in den Fign. 2 und 3 gezeigt, hängend unterzubringen. Gemäß Fig. 2 sind drei Pakete 26,28,30 in drei verschiedenen Ebenen von oben herabhängend innerhalb eines (nicht dargestellten) Kühlturmmantels angeordnet. In diesem Kühlturmmantel sind im Regelfall mehrere Pakete pro Ebene nebeneinander angeordnet, was in den Fign. 2 und 3 nicht gezeigt ist. Gemäß Fig. 2 hängen die Pakete 26 bis 30 in den verschiedenen Ebenen an Aufhängungselementen 32,34 bzw. 36, die sich von einer gemeinsamen Aufhängungsebene 38 herab erstrecken. Beim Ausführungsbeispiel gemäß Fig. 3 hängt lediglich das oberste Paket 26 über seine Aufhängungselemente 32 von der Aufhängungsebene 38 herab, während das nächst untere Paket 28 mit seinen Aufhängungselementen 34 an den Durchdringungselementen 20 des obersten Pakets 26 aufgehängt ist. In entsprechender Weise ist das unterste Paket 30 über seine Aufhängungselemente 36 an den Durchdringungselementen 20 des mittleren Pakets 28 aufgehängt.The strand-like penetrating elements 20 are now suitable to a plurality of packets 12 within a cooling tower as exemplified in the FIGS. 2 and 3 shown to house hanging. According to Fig. 2 For example, three packages 26, 28, 30 are arranged in three different levels from above in a cooling tower shell (not shown). In this Kühlturmmantel several packages per level are usually arranged side by side, which in the FIGS. 2 and 3 not shown. According to Fig. 2 Hang the packages 26 to 30 in the various levels of suspension elements 32,34 and 36, which extend from a common suspension plane 38 down. According to the embodiment Fig. 3 Only the top package 26 depends on its suspension elements 32 from the suspension level 38 down, while the next lower package 28 is suspended with its suspension elements 34 to the penetrating elements 20 of the top package 26. Similarly, the lowermost package 30 is suspended by its suspension members 36 from the penetrating members 20 of the middle package 28.

In Fig. 2 ist noch eine weitere alternative Ausgestaltung der hängenden Anordnung der Einbauten in einem Kühlturm gezeigt. Auf dem obersten Paket 26 ruht ein (in diesem Ausführungsbeispiel kleiner dimensioniertes) weiteres Paket 40 aus Gittermatten, Das hängend angeordnete oberste Paket 26 trägt also das weitere Paket 40. Eine derartige Anordnung von Paketen ist nicht nur für die oberste Ebene sondern auch für andere Einbau-Ebenen im Kühlturm denkbar.In Fig. 2 Yet another alternative embodiment of the hanging arrangement of the internals is shown in a cooling tower. On the uppermost package 26 rests a (smaller dimensioned in this embodiment) another Package 40 made of mesh mats, the topmost package 26 arranged hanging so also carries the other package 40. Such an arrangement of packages is conceivable not only for the top level but also for other installation levels in the cooling tower.

Fig. 4 zeigt beispielhaft, wie der Sicherungsvorsprung an den Enden 22 der Durchdringungselemente 20 ausgestaltet sein kann. Beispielhaft ist in Fig. 4 eine Hülse 42 aus insbesondere VA-Stahl gezeigt, die einen Außenflansch 44 aufweist.
