Description
Speisewasservorwärmer mit auf glatteü Röhren befestigten Rippenschalen Die Erfindung betrifft einen Wärmeaustauscher, insbesondere einen Speisewasservorwärmer mit auf glatten Rohren befestigten Rippen. Es ist bekannt, auf glatten Rohren gußeiserneRippenrohrstücke mittels Schrumpfen oder plattenförmige Stücke unter Verwendung eines wärmeleitenden Zwischenmittels durch Klemmschrauben zu befestigen. Auch ist es bekannt, Rippen auf glatte Rohre aufzuschweißen.Feed water preheater with ribbed bowls attached to smooth tubes The invention relates to a heat exchanger, in particular a feed water preheater with ribs attached to smooth tubes. It is known to use finned cast iron tubes on smooth tubes by means of shrinking or plate-shaped pieces using a thermally conductive To be fastened intermediate means by clamping screws. It is also known to have ribs to be welded onto smooth pipes.
Erfindungsgemäß werden diese aufzubr ingenden Rippenrohrstücke derart bemessen, daß sie zwei Rohre umfassen und nach der gemeinsamen Achsenebene in zwei Schalen geteilt. Diese Aufteilung ermöglicht es, Glattrohrvorwärmer ohne Zerstörung der Hauptrohrverbindungen nachträglich mit Rippen zu versehen und beschädigte Rohre auszuwechseln.According to the invention, these finned pipe pieces to be applied are in this way dimensioned so that they include two tubes and according to the common axis plane in two Shells divided. This division enables smooth tube preheaters without destruction retrofitting of the main pipe connections with ribs and damaged pipes to replace.
In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel veranschaulicht, und zwar stellt dar: Abb. i zusammengebaute Vorwärmerrohre mit Rippenschalen in Vorderansicht und zum Teil im Schnitt, Abb. 2 und 3 Einzelheiten der Rippenschale, und zwar Abb. 2 Schnitt durch die Linie B-B der Abb. 3, Abb. 3 Schnitt durch die Linie C-.C der Abb. q., Abb: 4 Vorderansicht der Rippenschale, Abb. 5 Teilschnitt durch die Linie D-D der Abb. i und seitliche Teilansicht der Vorwärmerelemente, Abb. 6 Teilschnitt durch die Linie F-F der Abb. 5.In the drawing, the invention is illustrated in an exemplary embodiment, namely shows: Fig. i assembled preheater pipes with ribbed shells in Front view and partly in section, Fig. 2 and 3 details of the ribbed shell, namely Fig. 2 section through the line B-B of Fig. 3, Fig. 3 section through the Line C-.C of Fig. Q., Fig: 4 Front view of the ribbed bowl, Fig. 5 Partial section through the line D-D of Fig. i and a partial side view of the preheater elements, Fig. 6 Partial section through the line F-F in Fig. 5.
Zwei zu einer Rohrschleife verbundene parallele glatte Rohre i werden von zwei nach der gemeinsamen Achsenebene der Rohre geteilten Schalen 2 umfaßt. Jede Schale besteht aus dem Mantel 3 und den Rippen Die Schalen werden an den Innenflächen mit einer plastischen Wärmeleitmasse, wie Graphitkitt, bestrichen und mit Hilfe von versenkt angeordneten Schrauben 5 auf die Rohre i aufgeklemmt. Damit eine gut wärmeleitende Verbindung erzielt wird, sind in den Innenflächen der Schalen 2 Kanäle 6 und Öffnun-gen 7 angebracht, durch die der überschüssige Kitt und die Luft entweichen können.Two parallel smooth tubes i connected to form a tube loop are encompassed by two shells 2 divided according to the common axis plane of the tubes. Each shell consists of the jacket 3 and the ribs. The inner surfaces of the shells are coated with a plastic heat-conducting compound, such as graphite putty, and clamped onto the tubes i with the aid of countersunk screws 5. In order to achieve a good heat-conducting connection, channels 6 and openings 7 are made in the inner surfaces of the shells 2, through which the excess cement and the air can escape.
Die Rohre werden auf ihrer geraden Länge mit solchen aneinandergereihten Schalen versehen. Die Endschalen haben kräftige Tragrippen 8 an den Enden, mit denen die Rohre aufeinandergelagert werden. Die Rohre tragen an den Enden Flanschen g zur Verbindung mit den Krümmern io.The pipes are lined up with such on their straight length Shells provided. The end shells have strong support ribs 8 at the ends with which the pipes are stacked on top of each other. The pipes have flanges g at the ends for connection with the manifolds io.
Der freibleibende Wandraum zwischen den Tragrippen wird mit Einsatzstücken i i ausgefüllt. Nach Herausnehmen dieser Stücke kann bei der in Abb. 5 dargestellten versetzten Anordnung die Rohrschleife so weit nach vorn herausgezogen werden, bis die Tragrippen frei sind und dann um 9o° gedreht werden, wodurch reichlich Spielraum für das Ausziehen in der Längsachse geschaffen wird.The remaining wall space between the support ribs is made with inserts i i filled out. After removing these pieces, the one shown in Fig. 5 can be used staggered arrangement, the pipe loop can be pulled out to the front until the support ribs are free and can then be rotated 9o °, creating ample leeway is created for pulling out in the longitudinal axis.
