Description
Wärmeaustauschapparat. Zur Versteifung der Rohrbündel von Wärmeaustauschapparaten (Vorwärmern, Kondensatoren usw.) wurden seither Stäbe, stabförmige eingeschraubte Anker, Distanzrohre usw. verwendet. Diese Art der Versteifungen haben den Nachteil, daß nicht nur ein Teil der Wärmeaustauschrohre wegfällt und der freie Querschnitt zwischen den Rohren unnötig vergrößert wird, sondern daß sie infolge ihrer Beanspruchung auf h'nickung bei I-löchstdrükken von 3o, 5o, ioo Atm, und mehr auch sehr teuer sind.Heat exchange apparatus. For stiffening the tube bundle of heat exchange devices (Preheaters, condensers, etc.) have been screwed in rods since then Anchors, spacer tubes, etc. used. These types of stiffeners have the disadvantage that not only part of the heat exchange tubes and the free cross-section are omitted between the tubes is unnecessarily enlarged, but that they as a result of their Stress On the other hand, with I-hole pressures of 3o, 5o, 100 atm, and more also very expensive are.
Dieser Übelstand wird durch vorliegende Erfindung bei ZVärmeaustauschapparaten, deren Endkammern unter Höchstdruck stehen, vermieden. Die mit festem und beweglichem Rohrboden ausgerüsteten Rohrbündel werden der günstigen Wärmeübertragung und billigen Herstellung wegen aus dünnwandigen Rohren hergestellt.This drawback is alleviated by the present invention in ZVärmeaustauschapparaten, whose end chambers are under maximum pressure, avoided. The ones with fixed and movable Tube sheet equipped tube bundles are of favorable heat transfer and cheap Manufactured because of thin-walled tubes.
Die Erfindung besteht darin, daß ein Widerlager am Mantel des Wärmeaustauschapparates für den beweglichen Rohrboden einerseits die Ausdehnung des Rohrbündels gestattet, anderseits die auf das Rohrbündel wirkenden achsialen Druckkräfte aufnimmt und das Einknicken der dünnwandigen Rohre verhütet.The invention consists in that an abutment on the jacket of the heat exchange apparatus for the movable tube sheet, on the one hand, the tube bundle can expand, on the other hand absorbs the axial pressure forces acting on the tube bundle and that Prevents the thin-walled tubes from buckling.
Abb. i stellt beispielsweise ein Widerlager dar, bestehend aus dem geteilten stufenförmigen Ring a mit der Stufe b und dem geschlossenen iberschiebering c, welcher den Ring a umfaßt.Fig. I shows, for example, an abutment, consisting of the split step-shaped ring a with the step b and the closed iberschiebering c, which includes the ring a.
Die Ringe a und c haben ihr gemeinsames ZViderlager am Grundring e der Stopfbuchse am Mantel des Wärmeaustauschapparates. Ring a und c sind in den ringförmigen Raum zwischen beweglichem Rohrboden und innerem Stopfbuchsenmantel d eingcpaßt. Sie bilden gleichzeitig und zusammen den Stopfbuchsengrundring und werden dadurch in ihrer Lage gehalten, wobei die Ringstufe b über den beweglichen Rohrboden greift, denselben achsial in der Druckrichtung festlegt und damit das Einknicken des Rohrbündels verhütet.The rings a and c have their common Z-abutment on the base ring e the stuffing box on the shell of the heat exchanger. Ring a and c are in the annular space between the movable tube sheet and the inner gland casing d fitted. At the same time and together they form the gland ring and are thereby held in their position, the ring step b over the movable Grips the tube sheet, fixes it axially in the pressure direction and thus the Prevents the tube bundle from buckling.
Abb.2 zeigt beispielsweise einen geteilten Ring k, welcher zwischen dem Grundring l der Stopfbuchse und dem beweglichen Rohrboden r seitlich durch Schrauben m vorgeschoben wird und das ZViderlager des beweglichen Rohrbodens bildet, den achsialen Druck aufnimmt, die Einknickung des Rohrbündels verhindert und dem Rohrbündel die Ausdehnung gestattet. -Abb.3 zeigt beispielsweise einen beweglichen Rohrboden r. an welchem ringartige Vorsprünge f vorhanden .sind, eine gleiche Anzahl ringartiger Vorsprünge sind am 'Mantel des Wärmeaustauschapparates vorgesehen, die als 'Viderlager dienen. Beim Einführen des Rohrbündels schieben sich die ringartigen Vorsprünge f des beweglichen Rohrbodens zwischen ringart-gen Vorsprüngen g des Mantels hindurch. Alsdann legen sich durch Drehung des Rohrbündels die Vorsprünge/ des beweglichen Rohrbodens über die Vorsprünge g des Mantels so, . daß die Vorsprünge g nun die Widerlager für die Vorsprünge f bilden, welche den achsiahn Druck aufnehmen und das Einknicken des Rohrbündels verhüten.Fig. 2 shows, for example, a split ring k, which is pushed forward laterally by screws m between the base ring l of the stuffing box and the movable tube sheet r and forms the counter bearing of the movable tube sheet, absorbs the axial pressure, prevents the tube bundle from buckling and the tube bundle the Expansion permitted. - Figure 3 shows, for example, a movable tube sheet r. on which ring-like projections f are present, an equal number of ring-like projections are provided on the jacket of the heat exchange apparatus, which serve as counter bearings. When the tube bundle is inserted, the ring-like projections f of the movable tube sheet slide through between ring-like projections g of the jacket. Then, by rotating the tube bundle, the projections / of the movable tube sheet lie over the projections g of the jacket so. that the projections g now form the abutments for the projections f, which absorb the axial pressure and prevent the tube bundle from buckling.
Hinter diesem Widerlager ist die Stopfbuchse angebracht, und zwischen dem Grundring i und dem Widerlager g ist genügend Spielraum für die Ausdehnung des Rohrbündels vorhanden.The stuffing box is attached behind this abutment, and between the base ring i and the abutment g there is enough leeway for the expansion of the Tube bundle present.
Abb.4 zeigt `beispielsweise einen beweglichen Rohrboden r einer Form mit ungleichen Achsen, z. B. elliptisch.Fig.4 shows, for example, a movable tube sheet r of a shape with unequal axes, e.g. B. elliptical.
Der bewegliche Rohrboden :- erhält ein Widerlager, ähnlich wie in Abb. 3 beschrieben. Eingeführt wird das Rohrbündel, indem die großen Achsen beider Teile zusammenfallen. Das Widerlager wird -.-bildet durch eine Drehung des Rohrbündels um 9o@.The movable tube sheet: - receives an abutment, similar to in Fig. 3 described. The tube bundle is introduced by the major axes of both Parts collapse. The abutment is -.- formed by rotating the tube bundle at 9o @.
Die Wärmeausdehnung erfolgt innerhalb einer dem Rohrboden r gleichgeformten Stopfbuchse s, deren Stopfbuchsentopf und Grundring durch überschieben eines im Äußeren runden, im Inneren der Stopfbuchse s gleichgeformten Ringes f gebildet wird.The thermal expansion takes place within a tube plate r shaped identically Stuffing box s, its stuffing box pot and base ring by sliding over an im Outer round, inside the stuffing box s identically shaped ring f is formed.
