Description

Die Erfindung bezieht sich auf einen umlaufenden Regenerativ-Vorwärmer, durch den die Wärme eines gasförmigen Mittels, z. B. Abgase einer Feuerung, auf ein arideres gasförmiges Mittel, z. B. Luft, übertragen wird. Derartige Vorwärmer haben den Nachteil, daß sich der Rotor während des Betriebes unter dem Einfluß der Temperatur verzieht. Es findet dadurch eine Relativbewegung zwischen dem Rotor und dem feststehenden Gehäuse statt, welche eine wirksame Abdichtung des Spaltes zwischen dem Rotor und dem Gehäuse erschwert.The invention relates to a circulating regenerative preheater, by which the heat of a gaseous agent, e.g. B. exhaust gases from a furnace another gaseous agent, e.g. B. air is transmitted. Such preheaters have the disadvantage that the rotor is under the influence of the Temperature warps. Thereby there is a relative movement between the rotor and the fixed housing instead, which effectively seals the gap between the rotor and the housing made more difficult.

Es ist Aufgabe der Erfindung, diesen Nachteil aufzuheben. Dies geschieht dadurch, d.aß der Spalt am Rande des Rotors durch eine Labyrint'hdichtung abgedichtet wird. Diese Labyrinthdichtung wird derart ausgeführt, daß an dem Gehäuse und an dem Rotor je zwei oder mehr konzentrische Ringe vorgesehen sind. Die am Rotor befestigten Ringe greifen in die Zwischenräume der am Gehäuse angeordneten Ringe ein und umgekehrt.It is the object of the invention to overcome this disadvantage. this happens as a result, the gap at the edge of the rotor is sealed by a labyrinth seal will. This labyrinth seal is designed so that on the housing and on the rotor is provided with two or more concentric rings. The ones attached to the rotor Rings engage in the spaces between the rings arranged on the housing and vice versa.

Die Zeichnung stellt in Abb. r Abis 3 ein Ausführungsbeispiel des Gegenstandes der Erfindung dar. In diesen Abbildungen bezeichnet a die Dichtungsleisten, die an den Zwischenwänden des Rotors befestigt sind, b die Ab,dichtplatten im Rotorsektor des Vorwärmers, c die Rollen, die bei einer übermäßigen Verwerfung des Rotors auf den Abdeck.-platten auflaufen, d die Dichtungsleisten für die Rollen, e eine Verzahnung zur besseren Abdichtung der Abdeckplatten b gegenüber dem Gehäuse, f die am Gehäuse befestigten konzentrischen Ringe der Labyrinthdichtung, g die am Rotor befestigten Ringe der Labyrinthdichtung.The drawing shows in Fig. R Abis 3 an embodiment of the subject matter of the invention. In these figures, a denotes the sealing strips that are attached to the intermediate walls of the rotor, b the Ab, sealing plates in the rotor sector of the preheater, c the rollers that are attached to excessive warping of the rotor on the cover plates, d the sealing strips for the rollers, e a toothing for better sealing of the cover plates b against the housing, f the concentric rings of the labyrinth seal attached to the housing, g the rings of the Labyrinth seal.

Da sich der Rotor im Betrieb im wesentlichen in axialer Richtung verzieht, so bewegen sich die konzentrischen Ringe g des Rotors in den Zwischenräumen zwischen den Ringen f des Gehäuses. Die Wirkung der Labyrinthdichtungwird dadurch nicht beeinträchtigt und eine zuverlässige Abdichtung auch bei starken Temperaturänderungen erreicht.Since the rotor is essentially distorted in the axial direction during operation, so move the concentric rings g of the rotor in the spaces between the rings f of the housing. The effect of the labyrinth seal is not impaired and a reliable seal is achieved even with strong temperature changes.
