Abstract

The heat exchanger has a cylindrical shell closed at top and bottom by flanged lids or domed ends. It has a set of tubes running vertically between upper and lower tube plates (4, 5) which leave upper and lower headers for the liquid flowing through the tubes. Both tube plates are inclined to the horizontal at the same angle in the same direction. This secures the known advantages of an inclined upper plate and at the same time makes possible the use of tubes which are all of the same length. This simplifies in all tubes. The heating medium can be steam or water and can flow through the shell or tubes.

Stehender, dampf- oder umsserbeheizter Wärmeaustauscher.Vertical, steam or externally heated heat exchanger.

Die Erfindung betrifft einen stehenden Wärmeaustauscher, bei dem das Heizmittel, Dampf oder Heißwasser, durch die Rohre oder den niantelraum des Apparates geführt werden kann, dessen Rohre in zwei, oben und unten angeordneten schrägstehenden Rohrplatten befestigt sind.The invention relates to an upright heat exchanger in which the Heating medium, steam or hot water, through the pipes or the niantel room of the apparatus can be guided, its tubes in two, above and below arranged inclined tube plates are attached.

An solche Wärmeaustauscher werden bestimmte Anforderungen gestellt, die sich vor allem auf ein geräuschfreies Arbeiten des Wärmeaustauschers bei der Beheizung mittels Dampf beziehen. Wie die Erfahrung lehrt, arbeiten stehende Wärmeaustauscher mit waagerechten oberen Rohrplatten, bei denen der Heizdampf durch die Rohre geführt wird nicht geräuschlos, uienn der Dampfdruck im Heizbündel größer ist, als der Druck das zu erbarmenden Wassers! In diesem Falle weist die Heizfläche, besonders der obere Rohrboden, in dem die Heizrohre befestigt sind, eine Temperatur auf, die höher ist, als die Siedetemperatur des zu erwärmenden Wassers. Dadurch entstehen auf der Wasserseite Dampfblasen, welche starke Geräusche beim Kondensieren verursachen. Auch bei Heißwasser als Heizmittel kenn dies der Fall sein, wenn die Temperatur des Heißwassers höher ist, als die Siedetemperatur des aufzuheizenden Wassers» Bei der Regelung eines dampfbeheizten Wärmeaustauschers durch Anstauung des Kondensats und eine dadurch hervorgerufene Abdeckung der Heizfläche, macht sieh die geschilderte Erscheinung besonders unangenehm bemerkbar, weil, anders als bei der dampfseitigen Regelung, der volle Dampfdruck mit seiner entsprechend hohen :..' Temperatur an der oberen Rohrplatte ansteht.Certain requirements are placed on such heat exchangers especially on a noise-free operation of the heat exchanger the heating by means of steam. As experience shows, upright heat exchangers work with horizontal upper tube plates in which the heating steam passed through the pipes is not noiseless, however Vapor pressure in the heating bundle is greater than the pressure to be pitied Water! In this case, the heating surface, especially the upper tube sheet, in which the heating pipes are attached, to a temperature that is higher than the boiling temperature of the water to be heated. Through this vapor bubbles arise on the water side, which cause loud noises when condensing. This also applies to hot water as a heating medium be the case when the temperature of the hot water is higher than the boiling temperature of the water to be heated »when regulating a steam-heated Heat exchanger by accumulation of the condensate and a cover of the heating surface caused by it, makes the described phenomenon particularly noticeable because, unlike the steam side Regulation, the full steam pressure with its correspondingly high: .. 'temperature is applied to the upper tube plate.

austauschers traten bei Kondendatanstauung an der oberen horiaontalen Rohrplatte Geräusche auf, meil sich, durch den notwendigen Abstand des Dampfeintrittsstutzans von dar Rohrplatte, zwischen dem Stutzen und der : Rohrplatte ein Hohlraum befindet, der bei voller Anstauung des Kondensate ebenfalls zu geräuschvollen Kondansationsschlägen führt.Exchanger occurred when condensation accumulated on the upper horiaontal Tube plate noises on, meil themselves, through the necessary distance of the Steam inlet nozzle from the tube plate, between the nozzle and the : Tube plate a cavity is located, which with full accumulation of the condensate also leads to noisy condensation beats.

Bekannt ist es bereits, zur Erziehlung eines geräuschlosen Arbeitens bei dampfbeheizten Röhranwärmeaustauschern, die obere Rohrplatte schräg anzuordnen, damit sich die an dar obBren Rohrplatte in dem beheizten Wedium bildenden Dampfblasen leicht ablösen» Z.B. D.Gm 1981862It is already known to teach people how to work silently In the case of steam-heated tubular heat exchangers, the upper tube plate is inclined to be arranged so that the vapor bubbles forming on the upper tube plate in the heated wedge easily detach »e.g. D.Gm 1981862

In allen diesen bekanntgewordenen Vorschlägen ist nur die obere Rohrplatte schräg angeordnet, während die untere Rohrplatte, bei aer die Schräglage nicht unbedingt erforderlich ist, waagerecht eingebaut wird« Dies macht erforderlich, daß praktisch alle Einzelrohre eine verschiedene Länge besitzen müssen, uias natürlich bei der Fertigung eines derartigen Apparates äußeret unerwünscht ist. UJeiter haben die Rohre, bedingt durch ihre unterschiesliche Länge, auch unterschiedliche Druckverluste, was zu einer ungleichmäßigen Strömungsverteilung führt.In all of these known proposals, only the top tube plate is arranged obliquely, while the lower tube plate, aer the inclined position is not absolutely necessary, it is installed horizontally «This makes It is necessary that practically all individual tubes must have a different length, uias, of course, in the manufacture of such an apparatus is outwardly undesirable. The pipes also have, due to their different Length, also different pressure losses, which leads to an uneven flow distribution.

Der Erfindung liegt die Aufgabe zugrunde, die geschilderten Nachteile auf eine möglichst einfache Art zu verhindern.The invention is based on the described disadvantages in the simplest possible way to prevent.

Diese Aufgabe wird erfindungsmäßig dadurch gelöst, daß nicht nur dia obere,-sondern auch die untere Rohrplatte schräg angeordnet wird. Diese einfache Maßnahme bringt eine ganze Reihe von Vorteilen. Der wichtigste Vorteil besteht darin, daß alle einzubauenden Rohre von gleicher Länge sind, was die Fertigung naturgemäß sehr erleichtert. Bedingt durch die gleiche Rohrlänge hat jedes Einzelrohr auch gleichen Druckverlust. Bai dar Fertigung können die Rohrplatten in vielen Fällen gemeinsam bearbeitet warden, so z,B. beim Drehen und Bohren. Dies ist jedoch nur möglich bei gleicher Form, wie sie die Beiden schrägen Rohrplatten besitzen. Überraschend wurde weiter festgestellt, daß bei einem Apparat mit zwei schrägen Rohrplatten die BauhBhe, bei gleicher Rohrlänge, gegenüber einem Apparat mit zwei geraden Rohrplatten reduziert wird. Da aus thermodynamischen Gründen die Rohrlänge möglichst groß sein soll, die Bauhöhe des Apparates jedoch durch den Aufstellungsort begrenzt ist, ist dieser Vorteil oft von besonders gjoßer Bedeutung.This object is achieved according to the invention in that not only dia upper, but also the lower tube plate is arranged at an angle. This simple measure has a number of advantages. The most important The advantage is that all the pipes to be installed are of the same length, which of course makes production much easier. Due to the the same pipe length, each individual pipe also has the same pressure loss. Bai In many cases, the tube plates can be processed together during production be, so z, B. when turning and drilling. However, this is only possible with the same shape as the two inclined tube plates. Surprisingly, it was also found that in an apparatus with two inclined tube plates the overall height, with the same pipe length, is reduced compared to an apparatus with two straight pipe plates. Because for thermodynamic reasons the pipe length should be as large as possible, but the overall height of the apparatus is limited by the place of installation, this advantage is often of particular advantage great meaning.

Der Apparat gemäß dar Erfindung kann ebenso vorteilhaft auch als heißuiasserbeheizter Wärmeaustauscher eingesetzt werden, da auch, bei Heißujasserbeheizung, wie schon ermähnt, Dampfbildung am Rohrbündel und damit Geräuschentwicklung möglich ist.The apparatus according to the invention can also advantageously be used as hot-water heated heat exchangers are used, as also, at Hot water heating, as already warned, formation of steam on the tube bundle and so that noise development is possible.

Bei heißujasserbeheizten Wärmeaustauschern wird das Heizwasser durch die Rohre geführt, damit bei Dampfblasenbildung im aufgeteilten Ulasser, die Dampfblasen an der oberen schrägen Rohrplatte geräuschlos abgeführt werden.In the case of hot water heated heat exchangers, the heating water is fed through the Pipes out so that in the case of vapor bubbles in the split Ulasser, the Steam bubbles can be dissipated silently on the upper inclined tube plate.

Da bei Heißwasserbeheizung im allgemeinen wesentlich längere Wärmeübertragungswege, d.h. größere Rohrlängen, notwendig sind, können mehrere Apparate gemäß der Erfindung in bekannter Weise hintereinander geschaltet werden.Since with hot water heating generally much longer heat transfer paths, i.e. larger pipe lengths are necessary, several apparatuses according to the invention can be connected in series in a known manner will.

Eine Ausführungsform das Erfindungsgegenstandes ist in der Zeichnung beispielsweise und rein schematisch dargestellt, und zwar zeigern Fig. 1t eine bekannte Ausführungsform Fig. 2i eine Ausführungsform gemäß der Erfindung.An embodiment of the subject matter of the invention is shown in the drawing, for example and shown purely schematically, namely Fig. 1t show a known embodiment 2i shows an embodiment according to the invention.

Bei der bekannten Ausführungsform gemäß Fig. 1 ist die obere Rohrplatte (1) schräg und die untere Rohrplatte (2) gerade angeordnet. Die Rohre (3) haben dadurch eine unterschiedliche Länge. Bei der Ausführung gemäß der Erfindung Fig. 2 sind die obere- (4) und untere Rohrplatte (5) schräg angeordnet und gleichförmig. Die Rohre (6) haben dadurch alle die gleiche Länge. Die Zeichnung zeigt auch vergleichsweise die Einsparung an Bauhöhe bei dem Apparat nach der Erfindung gegenüber einem Apparat normaler Ausführung. Ein weiterer wichtiger Vorteil der erfindungsgemäßen Konstruktion ist die Möglichkeit der einfaohen Reinigung der Rohrseite ohne Demontage, der Anschlußleitungen, da zur Reinigung nur die beiden Deckel (7) und (8) abgenommen werden müssen.In the known embodiment according to FIG. 1, the upper tube plate is (1) at an angle and the lower tube plate (2) arranged straight. As a result, the tubes (3) have different lengths. When executing according to the Invention Fig. 2, the upper (4) and lower tube plate (5) are inclined arranged and uniform. As a result, the tubes (6) all have the same length. The drawing also shows comparatively the savings in construction height in the apparatus according to the invention compared to an apparatus of normal design. Another important advantage of the construction according to the invention is the possibility of easy cleaning of the pipe side without dismantling, the connection lines, as only the two covers (7) and (8) are used for cleaning must be removed.

Die Erfindung ist nicht auf die beschriebene und dargestellte Ausführungsform beschränkt, vielmehr können Einzelheiten dem jeweiligen Bedarfsfall angepaßt werden, ohne von grundsätzlichen Erfindungsgedanken abzuweichen.The invention is not limited to the described and illustrated embodiment, but details can be used as required be adapted without deviating from the basic inventive concept.
