Description
Aufhängevorrichtung für ärrxaenuscher, insbesondere überhitzer Die Erfindung betrifft die besondere Ausgestaltung einer Aufhängevorrichtung für Wärmeaustauscher, insbesondere für überhitzer sowie für Verdampfungsvorwärmer, Zwangsumlaufdampferzeuger u: dgl. Sie geht dabei: von den bekannten Aufhängevorrichtungen aus, bei denen Hülsen verwendet werden, die durch Stege miteinander verbunden sind. Durch die Hülsen sind die in nebeneinander angeordneten Reihen und in der Höhe versetzt zueinander liegenden Rohre der Wärmeaustauscher hindurchgesteckt. Beieiner -derartigen Aufhängevorrichtung können die beheizten Rohre sich unabhängig voneinander ausdehnen, so daß die Verbindungsstege selbst und ihre Befestigungsstellen nicht beansprucht werden.Hanging device for arrxaenuscher, especially superheater die The invention relates to the particular configuration of a suspension device for heat exchangers, especially for superheaters as well as for evaporation preheaters, forced circulation steam generators u: like. It is based on: from the known suspension devices in which sleeves be used, which are connected to one another by webs. Through the pods are those in rows arranged next to one another and offset in height from one another Pipes of the heat exchangers pushed through. With such a suspension device the heated tubes can expand independently of each other, so that the connecting webs themselves and their attachment points are not claimed.
Die Erfindung besteht darin, daß die Stege seitlich so weit ausgebogen sind, daß sie einen Anschlag für die Hiilsen der benachbarten Rohrreihen bilden. Durch das Ausbiegen der Stege wird der Abstand zwischen den Rohrreihen gewahrt, und es wird durch das Anlegen der ausgebogenen Verbindüngsstege gegen die Hülsen der benachbarten Reihen verhindert, daß diese Stege an den Rohren selbst scheuern und sie dadurch schwächen: Um ein zu weites Verschieben der Hülsen auf den Rohren zu verhindern, bringt man vorteilhaft in üblicher Weise zu beiden Seiten der Hülsen kleine Schweißtropfen an, die als Anschlag für den Verschiebungsweg der Hülsen dienen.The invention consists in that the webs are bent laterally so far are that they form a stop for the sleeves of the adjacent rows of tubes. By bending the webs, the distance between the rows of tubes is maintained, and it is created by placing the curved connecting webs against the sleeves of the adjacent rows prevents these ridges from rubbing against the pipes themselves and thereby weaken them: To move the sleeves too far on the pipes to prevent, one brings advantageous in the usual way on both sides of the sleeves small drops of sweat that serve as a stop for the displacement path of the sleeves.
In der Zeichnung ist die Erfindung in einem Beispiel dargestellt. Abb. i zeigt einen Teil gebogener Rohre, .die z. B.. einem überhitzer angehören können, in Seitenansicht; Abb.2 zeigt einen Schnitt durch diese Rohre nach der Linie A-A der Abb. i.In the drawing, the invention is shown in an example. Fig. I shows a part of bent tubes. B. belong to a superheater can, in side view; Fig.2 shows a section through these pipes according to the line A-A of Fig. I.
Auf die Rohre a sind Hülsen b geschoben, die durch angeschweißte Stege c miteinander verbunden sind. Der Verschiebungsweg der Hülsen b auf den Rohren a wird durch kleine aufgeschweißte Höcker d begrenzt. Die Stege c sind, wie Abb. 2 zeigt; nach der Seite ausgebogen, so daß die Stege der Rohrreihe e sich gegen die Hülsen der Rohrreihe f legen; während die Stege der Rohrreihe f sieh gegen die Hülsen der Rohrreihe g legen usw. Dadurch wird der seitliche Abstand der Rohre gewahrt, und es wird vermieden, daß sich die Rohre infolge der Beheizung krümmen und ineinanderbiegen.Sleeves b , which are connected to one another by welded-on webs c, are pushed onto the tubes a. The displacement path of the sleeves b on the tubes a is limited by small welded-on humps d. The webs c are, as Fig. 2 shows; bent to the side so that the webs of the tube row e lie against the sleeves of the tube row f; while the webs of the row of tubes f see against the sleeves of the row of tubes g, etc. This maintains the lateral spacing of the tubes and prevents the tubes from bending and bending as a result of the heating.
Wie in Abb.2 bei lt gezeigt ist; können die Stege an den Rohrenden, an welchen die Rohre sich U-förmig umbiegen, in bekannter Weise fortgelassen werden, da hier der kurze U-Bogen der Rohre genügend Festigkeit besitzt. Dagegen ist die Anzahl der Hülsen-Steg-Verbindungen über die Länge der Rohre unbegrenzt.As shown in Fig.2 at lt ; the webs at the pipe ends, at which the pipes bend in a U-shape, can be omitted in a known manner, since the short U-bend of the pipes has sufficient strength here. In contrast, the number of sleeve-web connections is unlimited over the length of the tubes.
Als Baustoff wird man selbstverständlich einen solchen wählen, der den Wärmebeanspruchurigen durch die Beheizung gewachsenist.As a building material you will of course choose one that is able to cope with the heat demands due to the heating.
