Description

Mit Flüssigkeit zu berieselndes Luftbefeuchtungselemet für Luftbefeuchtungsvorrichtungen Die Erfindung betrifft ein mit Flüssigkeit zu berieselndes BuStbefeuchtungselement für Luftbefeuchtungsvorrichtungen, das aus einem porösen, plattenförmigen bzw. gitterförmigen Gebilde besteht.Air humidification element to be sprinkled with liquid for air humidification devices The invention relates to a brush moistening element to be sprinkled with liquid for air humidification devices, which consists of a porous, plate-shaped or grid-shaped Structure consists.

Bekannt sind selbstansaugende, in Blüssigkeit eintauchende Verdunstungselemente aus Löschpapier, Schwammtuch od. dgl. und ferner berieselte Verdunstungselemente in Form von Holzwollpressplatten, Metallgittern (Streckmetall), gehärtetem und geschnittenem Schaumgummi und Kunststoff-Fasermatten. Die bekannten selbstansaugenden Elemente haben den Nachteil, dass ihre Saughöhe und die Saugmenge begrenzt sind und dass sie geschlossene Oberflächen besitzen, die infolge Grenzschichtbildung nur eine begrenzte Verdunstung pro Flächeneinheit und vorbeigefuhrter Ltiftvolumeneinheit zulassen. Die begrenzte Saugmenge und begrenzte spezifische Verdunstung.lassen daher nur eine niedrige Verdunstungsleistung pro Flächeneinheit zu.Self-priming evaporation elements immersed in liquid are known from blotting paper, sponge cloth or the like and also sprinkled evaporation elements in the form of wood wool pressed panels, metal grids (expanded metal), hardened and cut Foam rubber and plastic fiber mats. The well-known self-priming elements have the disadvantage that their suction height and suction volume are limited and that they have closed surfaces which, as a result of boundary layer formation, only have one limited evaporation per unit area and unit volume of lift passed by allow. The limited Allow suction volume and limited specific evaporation therefore only a low evaporation rate per unit area.

Die berieselten Holzwöllpressplatten haben, bezogen auf eine Flächeneinheit, einen sehr hohen Luftwiderstand und neigen zur Bildung von Algen und Geruchzerscheinungen, so dass ihre Anwendung wegen ihrer hygienischen, energiemässigen und geräuschmässigen Nachteile bzulehnen ist. Mit Rücksicht darauf wurden bereits Verdunstungsgitter aus Streckmetall, gehärtetem Schaumgummi oder Kunstfasermatten in Befeuchtungsvorrichtungen eingesetzt. Diese Elemente haben jedoch den Nachteil, dass darüberrieselndes sser infolge der Oberflächenbeschaffenheit in Bahnen und Tropfen über diese Elemente nach unten läuit und die an sich zur Verfügung stehende grosse Oberflache nichtgleichmässig benetzt und entsprechend wirksam wird. Das hat zur Folge, dass ebenfalls nur eine begrenzte Verdunstungsleistung pro Flächeneinheit erreicht werden kann. Bei kalkhaltigem Wasser setzen sich zudem Kalkablagerungen entlang der bevorzugten Wasserbahnen ab, was zu einer weiteren Reduktion der gleichmässigen Beaufschlagung und damit der spezifischen Verdunstungsleistung führt.The sprinkled wood pellet press boards have, based on a unit area, very high air resistance and tend to form algae and odor phenomena, so that their application because of their hygienic, energy-related and noisy properties Disadvantages is to be rejected. With this in mind, there were already evaporation grids Made of expanded metal, hardened foam rubber or synthetic fiber mats in humidifying devices used. However, these elements have the disadvantage that sser due to the nature of the surface in tracks and drops over these elements downwards and the large surface available per se is not uniform wetted and becomes effective accordingly. As a result, only one limited evaporation capacity per unit area can be achieved. With calcareous Water also deposits limescale deposits along the preferred waterways, which leads to a further reduction in the uniform application and thus the specific evaporation capacity.

Der Erfindung liegt demgemäss die Aufgabe zugrunde, Verdunstungselemente zu-schaffen, mit denen die oben erwähnten Nachteile vermieden sind, d.h. die bei einem Minimum an Luftwiderstand ein Maximum an Verdunstungsleistung pro Flächeneinheit des Elementes und Volumeneinheit der vorbeigeführten Luft gewährleisten.The invention is accordingly based on the object of evaporation elements to-create, with which the above-mentioned disadvantages are avoided, i.e. the at a minimum of air resistance a maximum of evaporation capacity per unit area of the element and the unit of volume of the air passed by.

Diese Aufgabe ist mit einem Luftbefeuchtungselement der genannten Art gelöst, das nach der Erfindung dadurch gekennzeichnet ist, dass es aus einem an sich bekannten, gitterartigen tTragkörper, wie Drahtgeflecht, Streckmetallgitter, Kunststoffgeflecht, Keramikgitter odOdgl. besteht, dessen allseifige Oberflache mit einer dünnen Schicht aus saugfähigem Material gleichmässig überzogen ist.This task is with an air humidifier of the mentioned Type solved, which is characterized according to the invention in that it consists of a known, lattice-like t-support bodies, such as wire mesh, expanded metal lattice, Plastic mesh, ceramic grid or the like. exists whose all-soap surface is evenly covered with a thin layer of absorbent material.

Als s&ugfähige Materialien kommen dabei Scherbentone, gebramltes Caolin, hochsaugfähige Filtermassen, saugfähige Faserstoffe auf Kunststoffbasis tod. dgl in Frage.As absorbent materials, there are broken clay, crumbled Caolin, highly absorbent filter media, absorbent fibers based on plastic death. like in question.

Durch die erfindungsgemässe Ausbildung wird eine durchgehend gleichmässige Benetzung der gesamten Gitteroberfläche erreicht, was eine maximale Verdunstungsleistung pro Flächeneinheit zur Folge hat. Durchgeführte Messungen haben gezeigt, dass mit den erfindungsgemäss ausgebildeten Elementen überraschenderweise mehr als die doppelte Verdunstungsleistung pro Flächeneinheit und Volumeneinheit der vorbeigeführten Luft im Vergleich zu anderen bekannten Elementen erzielt werden kann.The design according to the invention results in a consistently uniform Wetting of the entire grid surface is achieved, resulting in a maximum evaporation rate per unit area. Measurements carried out have shown that with Surprisingly more than double the elements designed according to the invention Evaporation rate per unit area and unit volume of the air carried past compared to other known elements.

Die überzogenen Gitterelemente weisen vorteilhaft strömungstechnisch-günstige Formen auf, beispielsweise Rundstabelemente, Ovalstabelemente, Flachprofilelemente, wodurch bei einem Maximum der Oberfiäche ein Minimum an Luftwiderstand, bezogen auf eine bestimmte Strömungsgeschwindigkeit, erreicht wird, so dass die Befeuchtungsvorrichtung, in der die erfindungsgemässen Elemente eingesetzt sind, mit energiesparenden, geräuscharm laufenden Gebläsen, die ein Minimum an Aussenabmessungen aufweisen, betrieben werden kann.The coated grid elements advantageously have favorable flow conditions Shapes, for example round bar elements, oval bar elements, flat profile elements, whereby a minimum of air resistance is related to a maximum of the surface on a certain flow rate is reached, so that the humidifier, in which the elements according to the invention are used, with energy-saving, low-noise running blowers, which have a minimum of external dimensions, are operated can.

Weitere Einzelheiten werden nachfolgend an Hand einer zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.Further details are given below on the basis of a graphic Representation of exemplary embodiments explained in more detail.

In dieser Darstellung zeigt Fig. 1 ein unbeschichtetes Gitter im Kreuzverband mit angedeutetem Strömungsverlauf; Fig. 7a dasselbe Gitter gemäss Fig. 1 mit erfindungsgemässer Beschichtung; Fig. 2 ein unbeschichtetes Gitter im Diagonalkreuzverband; Figo 2a dasselbe Gitter gemäss Fig. 2 mit erfindungsgemässer Beschichtung; Fig. 3 einen unbeschichteten Streckmetallverband mit angedeutetem Strömungsverlauf und Fig. 3a denselben Streckmetallverband gemäss Fig. 3 mit Beschichtung.In this illustration, FIG. 1 shows an uncoated grid in a cross connection with indicated flow course; 7a shows the same grid according to FIG. 1 with the one according to the invention Coating; 2 shows an uncoated grid in a diagonal cross bracing; Figure 2a the same grid according to FIG. 2 with a coating according to the invention; Fig. 3 a uncoated expanded metal bandage with indicated flow course and FIG. 3a the same expanded metal bandage according to FIG. 3 with a coating.

Das bekannte Gitter nach Fig. 1 besteht aus einem Ovalstabkreuzverband, an dem die Flüssigkeit vorzugsweise an den Vertikalstäben entlangströmt, während die Querstababsohnitte 7 entweder zu schwach oder zu stark benetzt werden, je nachdem in welcher Weise die Flüssigkeit aufgetropft wird.The known grid according to Fig. 1 consists of an oval bar cross bracing, at which the liquid preferably flows along the vertical rods, while the Crossbar section 7 either too weakly or too heavily wetted, depending on the situation in which way the liquid is dripped on.

Der Rundstabdiagonalkreuzverband gemäss Fig. 2 zeigt ähnliche Strömungsverhältnisse, wobei beispielsweise die Flächen 8 und die Zwickel 9 einer gleichmässigen Flüssigkeitsverteilung nicht zugänglich gemacht werden können, dh. auch bei dieser bekannten Gitterform strömt die Flüssigkeit ohne zureichende gleichmässige Verteilung im wesentlichen vertikal auf kürzestem Wege nach unten. ähnliche Strömungsverhältnisse ergeben sich auch beispeilsweise bei dem bekannten Streckmetallverband 3 gemss Fig. 3.The round bar diagonal cross bracing according to FIG. 2 shows similar flow conditions, whereby, for example, the surfaces 8 and the gussets 9 have a uniform distribution of liquid cannot be made accessible, ie. also with this known grid shape the liquid flows essentially without sufficient uniform distribution vertically in the shortest possible way down. Similar flow conditions result also, for example, in the known expanded metal bandage 3 according to FIG. 3.

Wenn nun erfindungsgemäss diese als Beispiele angeführten bekannten Gitterverbände allseitig mit einer hoch saugfähigen Beschichtung beschichtet werden, wie dies in den Fig. 1a bis 3a dargestellt ist, so ergibt sich aufgrund der Saugfähigkeit des Beschichtungsmateriales eine gleichmässige Flüssigkeitsverteilung in der Beschichtung, und zwar auch in allen Querstegen, Zwickelbereichen und Schichtabschnitten, die gewissermassen im Strömungsschatten liegen.If now, according to the invention, these known as examples Lattice bandages are coated on all sides with a highly absorbent coating, as shown in FIGS. 1a to 3a, it results from the absorbency of the coating material an even distribution of liquid in the coating, including in all transverse webs, gusset areas and layer sections that to a certain extent lie in the shadow of the flow.
