Description

Die Erfindung betrifft ein Wetterschutzgitter für Schornsteine, umfassend einen Rahmen und in diesem angebrachte horizontale Wetterschutzlamellen, die in einer Reihe angeordnet sind.The invention relates to a weather protection grille for chimneys, comprising a frame and horizontal weather protection slats arranged in it, which are arranged in a row.

Solche Wetterschutzgitter dienen als Lüftungsgitter für Schornsteine, die mit Rauchgasrohren zur Rauchgasführung bestückt sind. Diese in der Regel aus einem korrosionsfesten Werkstoff bestehenden Rohre weisen eine äußere Isolierschicht auf, damit in den Rauchgasrohren eine Mindesttemperatur des Rauchgases aufrechterhalten wird, die einen Rest an Naturzug gewährleistet.Such weather protection grilles serve as ventilation grilles for chimneys that are equipped with flue gas pipes for flue gas routing. These pipes, which are usually made of a corrosion-resistant material, have an outer insulating layer so that a minimum temperature of the flue gas is maintained in the flue gas pipes, which ensures a residual natural draft.

Der Zwischenraum zwischen den isolierten rauchgasführenden Rohren und dem äußeren Betonschornstein, der als statischer Träger dient, muß belüftet werden. Zu diesem Zweck weist der Betonschornstein Belüftungsöffnungen auf, die mit den Wetterschutzgittern, auch Wetterschutzjalousien genannt, versehen sind. Die Wetterschutzgitter oder -jalousien in den Öffnungen des Betonschornsteins sind notwendig, um Beschädigungen und/oder Versottung der äußeren Isolierschicht der rauchgasführenden Rohre zu verhindern, die sonst infolge Regendurchschlag durch die Belüftungsöffnungen auftreten können. Hierzu ist zu bemerken, daß die Belüftungsöffnungen, die sich teilweise in großer Höhe an den Schornsteinen befinden, starken Einflüssen hinsichtlich Windgeschwindigkeiten, Beaufschlagung mit Regen, Schnee und Hagel ausgesetzt sein können. Bei ungünstigen Witterungsverhältnissen werden die Wetterschutzgitter zudem unbeabsichtigt einem Teil der abzuleitenden Rauchgase ausgesetzt, woraus sich eine starke korrosive Belastung ergeben kann.The space between the insulated flue gas pipes and the outer concrete chimney, which serves as a static support, must be ventilated. For this purpose, the concrete chimney has ventilation openings that are provided with the weather protection grilles, also called weather protection blinds. The weather protection grilles or blinds in the openings of the concrete chimney are necessary to prevent damage and / or sooting of the outer insulation layer of the flue gas pipes, which can otherwise occur as a result of rain break through the ventilation openings. It should be noted that the ventilation openings, some of which are located at high heights on the chimneys, can be exposed to strong influences with regard to wind speeds, exposure to rain, snow and hail. If the weather conditions are unfavorable, the weather protection grilles are also unintentionally exposed to some of the smoke gases to be discharged, which can result in a strong corrosive load.

Bei aus der Praxis bekannten Wetterschutzgittern der eingangs genannten Gattung bestehen daher der Rahmen und von diesem umfaßte horizontal angeordnete mechanische, stabile Wetterschutzlamellen aus hochkorrisionsbeständigem Kunststoff, nämlich Polypropylen. Die Wetterschutzlamellen sind in mindestens einer Reihe angeordnet, wobei jedoch eine einreihige Anordnung den Regendurchschlag bei ungünstigen Witterungsverhältnissen nicht mit Sicherheit verhindert. Daher gibt es auch mehrreihige Gitter, insbesondere drei- bis fünfreihige Gitter, die jedoch in kurzer Bauweise nicht befriedigend funktionieren.In the case of weather protection grilles of the type mentioned at the outset, the frame and the horizontally arranged, stable, mechanical weather protection slats which are encompassed by the latter are therefore made of highly corrosion-resistant plastic, namely polypropylene. The weather protection slats are arranged in at least one row, although a single-row arrangement does not reliably prevent the rain from breaking through in unfavorable weather conditions. Therefore, there are also multi-row grids, especially three to five-row grids, but they do not work satisfactorily in a short design.

Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde, ein Wetterschutzgitter für Schornsteine der eingangs genannten Gattung so weiterzubilden, daß auch bei kurzer Bauweise ein Regendurchschlag mit großer Sicherheit verhindert wird.The present invention is therefore based on the object of developing a weather grille for chimneys of the type mentioned in such a way that even with a short construction a rain breakdown is prevented with great certainty.

Diese Aufgabe wird gemäß dem kennzeichnenden Teil des Anspruchs 1 dadurch gelöst, daß hinter der Reihe Wetterschutzlamellen wenigstens ein Tropfenabscheidepaket in das Wetterschutzgitter eingebaut ist. Dies bedeutet, daß die Reihe Wetterschutzlamellen in dem Wetterschutzgitter, welches in die Schornsteinöffnung eingesetzt werden kann, sich weiter außen befindet, um den Winddruck abzuhalten und den größeren Teil der Feuchtigkeit - Regenwasser - abzuscheiden, das Tropfenabscheidepaket hingegen weiter innen, um auch die restliche Feuchtigkeit mit Sicherheit aus dem Luftstrom durch das Wetterschutzgitter zu entfernen. Damit ist eine kurze Bauweise realisiert, da die eine Reihe Wetterschutzlamellen in Verbindung mit dem Tropfenabscheidepaket genügt, um die gewünschte Abscheidewirkung mit Sicherheit zu erzielen.This object is achieved according to the characterizing part of claim 1 in that at least one droplet separating package is installed in the weather protection grille behind the row of weather protection slats. This means that the series of weather protection louvres in the weather protection grille, which can be inserted into the chimney opening, is located further outside to keep the wind pressure out and the greater part of the moisture - rainwater - to be separated, while the droplet separation package is located further inside to also remove the remaining moisture safely removed from the airflow through the weather grille. This results in a short design, since a series of weather protection slats in conjunction with the drop separation package is sufficient to achieve the desired separation effect with certainty.

Hierzu trägt nach Anspruch 2 die vertikale Anordnung der Tropfenabscheidelamellen in dem Tropfenabscheidepaket wesentlich bei, da der Luftstrom in der Reihe Wetterschutzlamellen zunächst vertikal, in dem Tropfenabscheidepaket jedoch horizontal umgelenkt wird. Durch die Umlenkung in verschiedenen Richtungen wird die Abscheidungswirkung optimiert.According to claim 2, the vertical arrangement of the droplet separating lamella in the droplet separating package contributes significantly to this, since the air flow in the row of weather protection slats initially vertically, but is diverted horizontally in the drop separation package. The separation effect is optimized by the deflection in different directions.

Je nach Einsatzzweck des Tropfenabscheidepakets in dem Wetterschutzgitter und dem erforderlichen freien Querschnitt können die Tropfenabscheidelamellen zweckmäßig mit einem gegenseitigen Abstand in dem Bereich von 25 bis 33 mm angeordnet sein, wozu eine Halterung dient.Depending on the intended use of the droplet separator package in the weather protection grille and the required free cross section, the droplet separating lamellae can expediently be arranged at a mutual distance in the range from 25 to 33 mm, for which purpose a holder is used.

Im einzelnen sind die Tropfenabscheidelamellen so ausgeformt, daß sie einlagige, gekrümmte Prallflächen bilden, auf denen die Regentropfen bei Auftreffen zu größeren Tropfen koagulieren. Zur Abführung auch großer Regenmengen sind die Wetterschutzlamellen innen und/oder außen mit je einer Fangnase geformt, welche die Abführung des aus den größeren Tropfen entstandenen Flüssigkeitsfilms durch Schwerkraft nach unten hin gewährleistet.Specifically, the droplet separating lamellae are shaped in such a way that they form single-layer, curved baffles, on which the raindrops coagulate to form larger droplets. To remove even large amounts of rain, the weather protection slats are formed on the inside and / or outside with a catch nose, which ensures that the liquid film formed from the larger drops is discharged downwards by gravity.

Zum Auffangen des abgeschiedenen und nach unten geleiteten Regenwassers weist das Wetterschutzgitter einen Sammelkasten auf, in den die Tropfenabscheidelamellen münden. Dabei erstreckt sich der Sammelkasten vorteilhaft bis unter die Reihe Wetterschutzlamellen. Ein in den Sammelkasten eingelassenes Ableitungsrohr dient zur Ableitung des gesammelten Wassers nach innen oder außen, je nach der bevorzugten Anordnung des Ableitungsrohrs an dem Sammelkasten.To collect the rainwater that has been separated and directed downwards, the weather protection grille has a collecting box into which the droplet separating lamellae open. The collecting box advantageously extends below the row of weather protection slats. A drain pipe embedded in the collection box serves to drain the collected water inwards or outwards, depending on the preferred arrangement of the drain pipe on the collection box.

In korrosionsbeständiger Ausführung des Wetterschutzgitters kann das Tropfenabscheidepaket vorteilhaft aus Kunststoff, insbesondere Polypropylen bestehen. Damit kann das gesamte Wetterschutzgitter aus einem einheitlichen hochkorrosionsbeständigen Werkstoff hergestellt werden.In the corrosion-resistant design of the weather protection grille, the droplet separation package can advantageously consist of plastic, in particular polypropylene. This means that the entire weather protection grille can be made from a uniform, highly corrosion-resistant material.

In vorteilhafter Weise eignet sich das Wetterschutzgitter mit den angegebenen Merkmalen für einen modularen Aufbau.The weather protection grille with the specified features is advantageously suitable for a modular construction.

Ein Ausführungsbeispiel des erfindungsgemäßen Wetterschutzgitters wird im folgenden anhand einer Zeichnung mit drei Figuren beschrieben. Es zeigen:

An embodiment of the weather protection grid according to the invention is described below with reference to a drawing with three figures. Show it:

the weather protection grille in a view from the front,
Fig. 2
the weather protection grille in a longitudinal section in the section plane BB according to FIG. 1 and
Fig. 3
the weather protection grille in a cross section as a plan view of the section plane AA in Fig. 2nd

In Fig. 1 ist ein in eine Öffnung eines Betonschornsteins einsetzbarer Rahmen mit 1 bezeichnet. Er weist auf seiner dargestellten Vorderseite im Abstand zueinander angeordnete vertikale Rundstäbe 2 auf, die als Vogelschutz dienen. Die Rundstäbe sind mit strichpunktierten Linien angedeutet.In Fig. 1, a frame which can be inserted into an opening of a concrete chimney is designated by 1. On its front side shown, it has vertical round bars 2 which are arranged at a distance from one another and serve as bird protection. The round bars are indicated with dash-dotted lines.

In Seitenwänden 3, 4 - siehe Fig. 3 - sind horizontal Wetterschutzlamellen 5 - 11 in einer vertikalen Reihe eingelassen.In side walls 3, 4 - see FIG. 3 - weather protection slats 5 - 11 are embedded horizontally in a vertical row.

Die Form und die Anordnung der Wetterschutzlamellen ergibt sich am besten aus Fig. 2. Hier ist auch zu sehen, wie die Form der Wetterschutzlamelle in eine obere Fangnase 12 bzw. 13 übergeht. Die übrige Form der Wetterschutzlamelle ist in der Praxis als Krümmung realisiert, anstatt der in Fig. 2 vereinfachend gezeigten geradlinig-abgeknickten Form.The shape and the arrangement of the weather protection slats can best be seen in FIG. 2. Here it can also be seen how the shape of the weather protection slat merges into an upper catch lug 12 or 13. In practice, the remaining shape of the weather protection lamella is realized as a curvature, instead of the straight-angled shape shown in a simplified manner in FIG. 2.

Aus Fig. 2 kann weiterhin ersehen werden, wie in Durchströmungsrichtung des Luftstroms von außen nach innen, die mit einem Pfeil 14 angedeutet ist, hinter der Reihe Wetterschutzlamellen ein Tropfenabscheidepaket 15 in dem Rahmen bzw. zwischen dessen Seitenwänden und oberer sowie unterer Wand 16, 17 angebracht ist. Unter der Reihe Wetterschutzlamellen befindet sich ein Sammelkasten 18, von dem ein Ableitungsrohr 19 hier nach innen reicht. (Innen und außen bezieht sich auf die Einbaulage des Wetterschutzgitters in dem nicht dargestellten Schornstein.) Der Sammelkasten hat eine obere Öffnung 20, um das von den Wetterschutzlamellen abgeschiedene und nach unten strömende Regenwasser zu sammeln und durch das Ableitungsrohr 19 abzuführen. Der Sammelkasten nimmt auch das von dem Tropfenabscheiderpaket aufgefangene und abgeleitete restliche Regenwasser auf, da vertikal angeordnete Tropfenabscheidelamellen direkt in den Sammelkasten münden.From FIG. 2 it can also be seen how in the direction of flow of the air flow from the outside inwards, which is indicated by an arrow 14, behind the row of weather protection slats, a droplet separating packet 15 in the frame or is attached between the side walls and upper and lower wall 16, 17. Under the row of weather protection slats is a collecting box 18, from which a discharge pipe 19 extends inwards. (Inside and outside refers to the installation position of the weather protection grille in the chimney, not shown.) The collecting box has an upper opening 20 in order to collect the rainwater separated from the weather protection slats and flowing downwards and to discharge it through the discharge pipe 19. The collecting box also receives the remaining rainwater collected and drained off by the drop separator package, since vertically arranged drop separating lamellae open directly into the collecting box.

In Fig. 3 sind nur zwei äußere Trofpenabscheidelamellen 21 und 22 dargestellt, die zu einer Gruppe von dreizehn Tropfenabscheidelamellen gehören, wobei jeweils zwei Tropfenabscheidelamellen, wie mit kurzen, nicht bezeichneten Strichen an dem Tropfenabscheidepaket 15 angedeutet, in äquidistanten Abständen zueinander angeordnet sind. Die horizontalen Abstände können in Abhängigkeit von dem Anwendungsfall und dem erforderlichen freien Querschnitt in dem Bereich zwischen 25 und 33 mm gewählt werden und durch ein spezielles, im einzelnen nicht dargestelltes Halterungssystem eingehalten sein.In Fig. 3 only two outer Trofpenabscheidelamellen 21 and 22 are shown, which belong to a group of thirteen droplet separating lamellae, two drop separating lamellae, as indicated by short, unspecified lines on the drop separating packet 15, are arranged at equidistant distances from each other. The horizontal distances can be selected depending on the application and the required free cross section in the range between 25 and 33 mm and can be maintained by a special mounting system, not shown in detail.

Die Tropfenabscheidelamellen, z.B. 21, 22, bilden einlagige, gekrümmte Prallflächen, obwohl die stark verkleinerte Darstellung in Fig. 3 nur gradlinige Abschnitte zeigt. Die Abscheidung der Regentropfen erfolgt hier durch Auftreffen der Regentropfen an den Prallflächen bzw. Prallwänden und infolgedessen Koagulation zu größeren Tropfen. Die horizontale Umlenkung des Luftstroms in dem Tropfenabscheidepaket 15 ist mit dem Pfeil 16 angedeutet.The droplet separation lamellae, e.g. 21, 22, form single-layer, curved baffles, although the greatly reduced illustration in FIG. 3 shows only straight-line sections. The raindrops are separated here by the raindrops hitting the impact surfaces or impact walls and, as a result, coagulating into larger drops. The horizontal deflection of the air flow in the droplet separation package 15 is indicated by the arrow 16.

Zur Abführung auch großer Regenmengen ist an den Tropfenabscheidelamellen eine äußere Fangnase 23 bzw. 24 ausgebildet, die zur Abführung des Flüssigkeitsfilms durch die Schwerkraft nach unten in den Sammelkasten 18 dient. Eine zweite innen an jeder Tropfenabscheidelamelle ausgebildete Fangnase, die analog wie die äußere Fangnase wirkt, ist in Fig. 3 nicht hervorgehoben.To remove even large amounts of rain, an outer catch 23 or 24 is formed on the drop separating lamellae, which serves to discharge the liquid film by gravity down into the collecting box 18. A second catch nose formed on the inside of each drop separating lamella, which acts analogously to the outer catch nose, is not emphasized in FIG. 3.

Durch die oberen Fangrinnen 12, 13 der Wetterschutzlamellen erfolgt also eine Grobabscheidung des Regenwassers, während an den inneren Tropfenabscheidelamellen eine Feinabscheidung durchgeführt wird. Somit ist mit nur zwei Reihen Lamellen eine praktisch vollkommene Abscheidung des Wassers bei kurzer Bauweise des Wetterschutzgitters gewährleiset. Dabei stellt sich die praktisch vollkommene Abscheidung durch die Kombination der vertikalen Luftstromumlenkung mit den Wetterschutzlamellen sowie der horizontalen Umlenkung mit den Tropfenabscheidelamellen ein. - Durch die damit mögliche kurze Bauweise des Wetterschutzgitters ist eine einfache Integration in die Schornsteinwand erreichbar.A rough separation of the rainwater takes place through the upper gutters 12, 13 of the weather protection slats, while a fine separation is carried out on the inner droplet separation slats. With only two rows of slats, a practically complete separation of the water is guaranteed with a short construction of the weather protection grille. The practically perfect separation is achieved by the combination of the vertical air flow deflection with the weather protection slats and the horizontal deflection with the drop separation slats. - The short design of the weather protection grille makes it easy to integrate into the chimney wall.
