Kontaktkörper für Flüssigkeit und Gas, vor allem für Anwendung in Luftbefeuchtern und KühltürmenContact body for liquid and gas, especially for use in air humidifiers and cooling towers
Die vorliegende Erfindung betrifft einen Kontaktkörper für Flüssigkeit und Gas gem. dem Oberbegriff des Patentanspruches 1. Die Flüssigkeit und das Gas können aus Wasser bzw· Luft bestehen, und ein wichtiges Anwendungsgebiet der Erfindung sind Luftbefeuchter. Die Erfindung ist jedoch nicht hierauf begrenzt.The present invention relates to a contact body for liquid and gas according to the preamble of claim 1. The liquid and the gas can consist of water or air, and air humidifiers are an important field of application of the invention. the However, the invention is not limited to this.
Zur Anfeuchtung von Luft in Lüftungsanlagen werden gewöhnlich Luftbefeuchter vom sog. Einsatztyp angewendet. Die eingehende Luft wird hierbei dadurch befeuchtet, daß sie an einem Kontaktkörper vorübergeleitet wird, dessen Oberflächen durch kontinuierliches oder unterbrechendes Wasserbegießen naß gehalten werden. Die Luft strömt gewöhnlich horizontal durch den Kontaktkörper, während das Wasser oben am Kontaktkörper zugeführt wird und längs dessen Kontaktflächen abwärts strömt. Die Zuführung des Wassers kann z.B. mit Hilfe eines perforierten Rohrsystemes erfolgen. Eine gute Befeuchtung der Luft setzt voraus, daß das Wasser so gleichmäßig wie möglich über die Flächen des Kontaktkörpers verteilt wird.Air humidifiers are usually used to humidify air in ventilation systems of the so-called insert type. The incoming air is humidified by passing it past a contact body whose surfaces are kept wet by continuous or intermittent pouring of water. The air usually flows horizontally through the contact body, while the water is supplied at the top of the contact body and down along its contact surfaces flows. The water can be fed in using a perforated pipe system, for example. A good humidification of the air assumes that the water is distributed as evenly as possible over the surfaces of the contact body.
Der Kontaktkörper besteht oft aus einer großen Anzahl parallel aufgestellter gefalteter Kontaktplatten, die sich gegeneinander abstützen oder mit Abstandsgliedern versehen sind, so daß Kanäle passender Größe gebildet werden, um den Durchgang der Wasser- und Luftströme · durch den Kontaktkörper zu ermöglichen. Ein Beispiel eines solchenThe contact body often consists of a large number of parallel ones folded contact plates, which are supported against each other or are provided with spacers, so that channels more fitting Size are formed in order to allow the passage of the water and air currents · through the contact body. An example of one

Kontaktkörpers, ist in der schwedischen Patentanmeldung Nr. 7502696-3 beschrieben. Bei Kontaktkörpern dieser Art besteht die Schwierigkeit, bei sehr geringem Wasserfluß, insbesondere bei Anwendung von Platten aus nicht-hygroskopischem, aber auch aus schwach hygroskopischem Material, eine gleichmäßige Wasserverteilung über die Platten zu erhalten. 'Contact body, is in Swedish patent application No. 7502696-3 described. In the case of contact bodies of this type, there is a problem with very little water flow, especially when using Plates made of non-hygroscopic, but also of weakly hygroscopic material, to obtain an even distribution of water over the plates. '
Die vorliegende Erfindung hat die Aufgabe, eine gleichmäßigere Wasserverteilung und bessere Wasserhaltung über dem Kontaktkörper bei geringem Wasserfluß zu bewirken. Die Erfindung ist dadurch gekennzeichnet, daß die Falten, die auf den Platten mit im wesentlichen vertikalen Falten in der Grobstruktur die Feinstruktur bilden, im wesentlichen horizontal sind, während die Falten, die auf den Platten mit im wesentlichen horizontalen Falten in der Grobstruktur die Feinstruktur bilden, im wesentlichen vertikal sind, um eine gute Haftung und günstige Verteilung der Flüssigkeit auf den Platten zu bewirken.The present invention aims to achieve a more even distribution of water and to bring about better water retention over the contact body when the water flow is low. The invention is characterized in that that the folds which form the fine structure on the plates with essentially vertical folds in the coarse structure, essentially are horizontal, while the folds on the panels with essentially horizontal folds in the coarse structure form the fine structure are essentially vertical in order to achieve good adhesion and favorable distribution of the liquid on the plates.
Geeignete Ausführungsformen sind in den beigefügten ühteransprüchen definiert.Suitable embodiments are in the accompanying claims Are defined.
Der Erfindung liegt die Einsicht zugrunde, daß das Wasser, das einer Kontaktplatte zugeführt wird, die mit einer im wesentlichen vertikalen, einer im wesentlichen horizontalen Feinstruktur überlagerten Grobstruktur versehen ist, von der Feinstruktur über die Platte verteilt wird, während es von der Grobstruktur zurückgehalten wird, so daß ein Mitreißen von Wassertropfen im Luftstrom ausgeschaltet wird. Umgekehrt strebt die Grobstruktur auf einer Koritaktplatte, die mit einer im wesentlichen horizontalen, einer im wesentlichen vertikalen Feinstruktur überlagerten Grobstruktur versehen ist, danach, das Wasser zu verteilen, während die Feinstruktur danach strebt, das Wasser zurückzuhalten. Für die Erfindung ist somit wesentlich, daß Faltenhöhe, Wellenlänge und -form einander so·, angepaßt werden, daß die gewünschte Abwägung zwischen Verteilung und Zurückhaltung des Wassers erhalten wird.The invention is based on the insight that the water that one Contact plate is supplied, which has a substantially vertical, a substantially horizontal fine structure superimposed coarse structure is provided, is distributed over the plate by the fine structure, while it is retained by the coarse structure, so that the entrainment of water droplets in the air stream is eliminated. Conversely, the coarse structure strives on a Koritakt plate, which with a substantially horizontal coarse structure superimposed on a substantially vertical fine structure, according to which To distribute water while the fine structure strives to hold the water back. It is therefore essential for the invention that The height of the folds, the wavelength and the shape of the folds are adapted to one another in such a way that the desired trade-off between distribution and retention of water is obtained.
Die Erfindung wird nachstehend unter Bezugnahme auf die beigefügten Zeichnungen näher beschrieben, in denenThe invention is described below with reference to the accompanying drawings Drawings described in more detail in which
