Description
Vorrichtung zur Rückgewinnung der Schwadenwärme In Zellstoff- und Papierfabriken und ähnlichen Betrieben kommen bei den Arbeitsprozessen große Wassermengen zur Verdampfung, die durch Abluftschlote ins Freie entweichen; oder es werden Einrichtungen verwendet, die dem Dampfluftgemisch die Wärme entziehen und damit aus dem Freien genommene gefilterte Luft erwärmen. Solche Anlagen, durch die große Wärmemengen zurückgewonnen werden, arbeiten folgendermaßen: Ein Abluftventilator saugt durch eine Batterie von Wärmeaustauschzellen das Dampfluftgemisch an und befördert die abgekühlte Schwadenluft ins Freie. Im OOuerstrom wird durch den Wärmeaustauscher Frischluft gesaugt, die nach entsprechender Erwärmung durch einen Ventilator einem Verwendungszweck zugeführt wird. Während die Frischluft waagerecht durch die Wärrneaustauschzellen geführt wird, muß das Dampfluftgemisch senkrecht durch die Zellen strömen, damit das sich bildende Kondensat in die unter dem @Ä'ärmeaustauscher angebrachte Wanne abfließen kann. Bei bekannten Ausführungen solcher Batterien sind zur seitlichen Begrenzung der Kanäle die Kanten der Platten abgewinkelt und die abgewinkelten Kanten durch Umfalzen mit den Kanten der benachbarten Platten verbunden. Demgegenüber besteht die vorliegende Erfindung darin, daß an jeder Platte jeweils zwei zusammenstoßende Kanten abgewinkelt sind. Durch eine derartige Maßnahme wird einerseits die Herstellung vereinfacht und verbilligt, andererseits werden die Stoß- bzw. Dichtungsstellen auf ein Mindestmaß herabgesetzt.Device for the recovery of steam heat in pulp and Paper mills and similar companies use large amounts of water during the work processes for evaporation, which escape into the open through exhaust air ducts; or there will be bodies are used, which extract the heat from the steam-air mixture and thus from the open air heat the filtered air taken. Such systems, due to the large amounts of heat are recovered work as follows: An exhaust fan sucks through a battery of heat exchange cells to the steam air mixture and transports the cooled vapor air into the open air. In the OOuerstrom is through the heat exchanger Fresh air is sucked in, which after appropriate heating by a fan a Purpose is supplied. While the fresh air passes horizontally through the heat exchange cells is performed, the vapor-air mixture must flow vertically through the cells so that the condensate that forms in the pan under the heat exchanger can drain. In known designs of such batteries are to the side Bounding the channels the edges of the angled panels and the angled edges connected by crimping to the edges of the adjacent panels. In contrast, there is the present invention is that on each plate two colliding Edges are angled. Such a measure, on the one hand, the production Simplified and cheaper, on the other hand, the joints or sealing points reduced to a minimum.
Es ist weiterhin bekannt, an den vier Ecken des Plattenpakete;, welches die Kanäle bildet, Distanzbolzen durch zwei zwischen den Platten liegende Distanzhülsen hindurchzufiihren. Bei der vorliegenden Erfindung werden dabei zwei zwischen denselben Trennwänden liegende Hülsen durch einen mit dem Gehäuserahmen des Plattenwärmeaustauschers verschraubten Arm miteinander verbunden. Durch diese Konstruktion wird die Montage vereinfacht und der Plattenaustauscher in seiner Festigkeit wesentlich verbessert.It is also known, at the four corners of the plate pack ;, which Forms the channels, spacer bolts through two spacer sleeves between the plates to lead through. In the present invention, there are two between the same Partition walls lying sleeves through a with the housing frame of the plate heat exchanger bolted arm connected together. This construction makes the assembly simplified and the plate exchanger significantly improved in its strength.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen Fig. 1 bis 3 verschiedene Ansichten des Wärmeaustauschers, Fig.4 und 5 die Zusammenfügung der einzelnen Zellenplatten zli fertigen Zellen, die mit A und I' bezeichnet sind und die Strömungsrichtung angeben, Fig.6 in schaubildlicher Darstellung eine Zellenwand mit Abwinkelung, Fig.7 einen senkrechten Schnitt durch eine Batterie mit Distanzhülsen und Distanzbolzen, Fig. $ einen Versteifungsarm. Jede Zellenplatte 1 wird durch Umkantung der benachbarten Seiten 2 und 3 nach Fig. 6 mit der nächsten Zellenplatte verbunden und durch weitere Umkantung von 4 und 5 und Umbördeln luftdicht mit dieser geschlossen, so daß Kanäle im Kreuzstrom entstehen. Zwischen den Zellwänden 6, 7, 8 (Fig. 7) liegen Distanzhülsen 9, durch welche an den Ecken der Zellen Distanzbolzen 10 hindurchgeschoben sind. Einige dieser Distanzhülsen 11 sind verstärkt ausgeführt und durch Arme 12 miteinander verbunden. Die Arme sind mittels Schrauben 13 an dem Gehäuserahmen 14 angeschraubt.An exemplary embodiment of the invention is shown in the drawing. 1 to 3 show different views of the heat exchanger, FIGS. 4 and 5 the assembly of the individual cell plates zli finished cells, which are denoted by A and I 'and indicate the direction of flow, FIG. 6 is a diagrammatic representation of a cell wall with angled, 7 shows a vertical section through a battery with spacer sleeves and spacer bolts, FIG. $ A stiffening arm. Each cell plate 1 is connected to the next cell plate by folding the adjacent sides 2 and 3 according to FIG. 6, and by further folding 4 and 5 and flanging it, it is closed airtightly with this, so that cross-flow channels are created. Between the cell walls 6, 7, 8 (FIG. 7) there are spacer sleeves 9 through which spacer bolts 10 are pushed at the corners of the cells. Some of these spacer sleeves 11 are reinforced and connected to one another by arms 12. The arms are screwed to the housing frame 14 by means of screws 13.
