Abstract

1. Filling material for the heat exchange of substances, in particular for the cooling of water by air in cross- and/or counter-current in cooling towers, comprising superposed plates which are joined together at the contact points and in which open ducts polygonal in cross-section are formed, characterized in that the ducts (2) have twisted wall surfaces (1).

Description

Die Erfindung betrifft einen Füllkörper für den Wärmeaustausch von Stoffen, insbesondere für die Abkühlung von Wasser durch Luft im Kreuz- und/oder Gegenstrom in Kühltürmen, bestehend aus aufeinandergeschichteten und an den Berührungsstellen miteinander verbundenen Platten.The invention relates to a packing for the heat exchange of substances, in particular for the cooling of water by air in cross-flow and / or countercurrent in cooling towers, consisting of plates which are stacked and connected to one another at the contact points.

Derartige Füllkörper sind z.B. aus der DE-PS 28 15 343 bekannt. Aus der DE-PS 21 22 537 ist ein Füllkörper bekannt, der zur Erzeugung einer Turbulenz der Wärmeaustausch-Medien in den Wänden der senkrechten, parallel zur Anströmungsrichtung der Medien verlaufenden Kanäle spiralförmige Führungsflächen in Form von Einkerbungen aufweist. Wie sich gezeigt hat, reichen diese spiralförmigen Einkerbungen nicht aus, um eine zur Verbesserung des Wärmeaustausches ausreichende Turbulenz der strömenden Medien zu bewirken.Such fillers are e.g. known from DE-PS 28 15 343. From DE-PS 21 22 537 a packing is known which has spiral guide surfaces in the form of notches for generating turbulence of the heat exchange media in the walls of the vertical channels which run parallel to the flow direction of the media. As has been shown, these spiral indentations are not sufficient to cause sufficient turbulence of the flowing media to improve the heat exchange.

Die der Erfindung zugrundeliegende Aufgabe besteht demgemäß darin, Mittel anzugeben, durch die eine stärkere Turbulenz zur Verbesserung des Wärmeaustausches zwischen den Medien und gleichzeitig eine Erhöhung der Steifigkeit des Füllkörpers erreicht werden kann.The object on which the invention is based is accordingly to provide means by means of which greater turbulence can be achieved to improve the heat exchange between the media and at the same time increase the rigidity of the packing.

Zur Lösung dieser Aufgabe wird ein Füllkörper mit den im Anspruch 1 gekennzeichneten Merkmalen vorgeschlagen.To achieve this object, a packing with the features characterized in claim 1 is proposed.

Der Füllkörper wird durch Schichten und Verbinden von Platten in der üblichen Weise hergestellt. Wesentliches Merkmal der Erfindung ist die verwundene (in sich verdrehte) Ausformung der Wandflächen der Strömungskanäle, die im Gegensatz zu bisher bekannten Füllkörpern beim Aufeinanderlegen von gewellten oder gefalteten Platten Wellenberg gegen Wellental nicht rundherum geschlossen, sondern mindestens teilweise offen sind, so daß freie Durchlässe quer zu den geformten Kanälen zwischen benachbarten Platten vorhanden sind und die Strömungsmedien aus Kanälen in einer Platte in die benachbarter Platten übertreten können. Dies hat eine Reihe von Vorteilen.The packing is made by layering and joining plates in the usual way. An essential feature of the invention is the twisted (twisted) shape of the wall surfaces of the flow channels, which, in contrast to previously known fillers, when corrugated or folded plates wave crest against wave trough are not closed all around, but are at least partially open, so that there are free passages transverse to the shaped channels between adjacent plates and the flow media from channels in one plate can pass into the adjacent plates. This has a number of advantages.

Durch den verwundenen Verlauf der Kanalwandflächen wird einmal eine turbulente Rotation der Strömung erreicht, durch die eine fortlaufende Umschichtung innerhalb des Strömungsmediums beim Entlangströmen an den verwundenen Wandflächen erfolgt, die immer wieder andere Teilchen an die aktive Wärmeaustausch-Oberfläche führt. Dies ist bei der aus der DE-PS 21 22 537 bekannten Ausführung eines Füllkörpers nicht im gleichen Maß gewährleistet.Due to the twisted course of the channel wall surfaces, a turbulent rotation of the flow is achieved, through which there is a continuous redeployment within the flow medium as it flows along the twisted wall surfaces, which always leads other particles to the active heat exchange surface. This is not guaranteed to the same extent in the embodiment of a packing known from DE-PS 21 22 537.

Die Turbulenzerhöhung wird durch die erwähnten Durchtrittsöffnungen zwischen Kanälen einer Platte zu den Kanälen benachbarter Platten noch verstärkt, wobei die Verbindungspunkte der Platten den ablaufenden Medienfilm teilen und zusätzliche Turbulenz bewirken. Mit größerer Zahl von Verbindungspunkten wird auch die Turbulenz erhöht. Die Durchlässe zwischen benachbarten Platten ermöglichen auch ein kegelförmiges Auffächern des zu kühlenden Strömungsmediums, was von Bedeutung ist, wenn infolge einer Störung an der Verdüsungsvorrichtung das Medium als Strahl auf den Füllkörper trifft.The increase in turbulence is further increased by the passage openings mentioned between channels of one plate to the channels of adjacent plates, the connection points of the plates dividing the running media film and causing additional turbulence. With a larger number of connection points, the turbulence is also increased. The passages between adjacent plates also allow a conical fanning out of the flow medium to be cooled, which is important if the medium hits the filler body as a jet as a result of a malfunction in the atomizing device.

Durch die verwundenen Wände der Kanäle in den Platten wird ferner die Füllkörpersteifigkeit erhöht, da die Flächenverwindung einen gradlinigen Verlauf von eventuell auftretenden Knicklinien behindert und damit den Widerstand gegen Auffächerung der Platten wesentlich vergrößert.The twisted walls of the channels in the plates further increase the stiffness of the packing, since the surface twisting hinders a straight line of any buckling lines that may occur and thus significantly increases the resistance to fanning out of the plates.

Der Querschnitt der Kanäle kann beliebig groß und drei-oder mehreckig ausgebildet sein. Die Ausformung der offenen Kanäle in den Platten erfolgt in der gleichen Weise wie die bekannter gewellter oder gefalteter Füllkörperplatten in einer entsprechend gestalteten Form.The cross section of the channels can be of any size and triangular or polygonal. The open channels in the plates are shaped in the same way as the known corrugated or folded packing plates in a correspondingly designed form.

Die Verbindung der Platten kann punktweise erfolgen. Gemäß einer vorteilhaften Ausgestaltung der Erfindung können aber auch abstandsweise definierte Verbindungsflächen gebildet sein, an denen die Platten miteinander verbunden werden. Die Festigkeit der Plattenverbindung wird hierdurch verbessert.The plates can be connected point by point. According to an advantageous embodiment of the invention, however, it is also possible to form spaced-apart connection surfaces on which the plates are connected to one another. This improves the strength of the panel connection.

Die Kanäle können geradlinig ausgebildet sein, vorzugsweise aber auch in Medienströmungsrichtung einen abgeknickten Verlauf haben, wodurch eine weitere Verstärkung der Strömungsturbulenz erzeugt und die Formsteifigkeit weiter erhöht wird.The channels can be designed in a straight line, but preferably also have a bent course in the direction of the media flow, as a result of which a further intensification of the flow turbulence is generated and the rigidity is further increased.

Diesem Zweck dienen auch die, vorzugsweise zur Strömungsrichtung geneigt verlaufenden Sicken in den Wänden der vorteilhafterweise aus Kunststoff bestehenden Platten.This purpose is also served by the beads in the walls of the plates, which are advantageously made of plastic, preferably extending inclined to the direction of flow.

Die Kanäle sollen vorzugsweise zur Medien-Anströmrichtung geneigt sein. Das in der Regel als Tropfen in den Füllkörper eintretende Medium wird dann zu einer filmartigen Strömung zusammengefaßt und in den Kanälen definiert geführt. Der Neigungswinkel ist hierbei beliebig.The channels should preferably be inclined to the media flow direction. The medium, which usually enters the packing as a drop, is then combined into a film-like flow and guided in a defined manner in the channels. The angle of inclination is arbitrary.

Gemäß einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Füllkörpers können die Platten so geschichtet .sein, daß die Kanäle in benachbarten Platten kreuzweise zueinander verlaufen. Hierdurch entsteht einmal eine Vielzahl von Kreuzungspunkten, an denen die Platten miteinander verbunden werden können und die die erwähnte Turbulenzerhöhung bewirken. Zum anderen entsteht hierdurch eine weitere Turbulenzerhöhung infolge der Umlenkung des Strömungsmediums beim Übertritt aus Kanälen einer Platte in die benachbarter Platten.According to a further advantageous embodiment of the packing according to the invention, the plates can be layered such that the channels in adjacent plates run crosswise to one another. This creates a large number of intersection points at which the plates can be connected to one another and which cause the aforementioned increase in turbulence. On the other hand, this results in a further increase in turbulence as a result of the deflection of the flow medium when passing from channels in one plate into the adjacent plates.
