Description

Wärmeaustauschvorrichtung. Der Gegenstand der Erfindung ist ein Wärmeaustauschapparat (Abdampfvorwärmer usw.) mit einem festen und einem beweglichen Rohrboden, bei welchem Rohrbündel und Endkammern unter hohem Druck stehen und das Rohrbündel der günstigen Wärmeübertragung und billigen Herstellung halber aus dünnwandigen Rohren besteht. Das Rohrbündel kann dem hohen achsialen Druck nicht widerstehen.Heat exchange device. The subject of the invention is a heat exchange apparatus (Exhaust steam preheater, etc.) with a fixed and a movable tube sheet, in which The tube bundle and end chambers are under high pressure and the tube bundle is cheap Heat transfer and cheap production for the sake of thin-walled tubes. The tube bundle cannot withstand the high axial pressure.

Das Rohrbündel dehnt sich infolge der Erwärmung aus, während die im Rohrbündel und den Endkammern auftretenden Druckkräfte dasselbe auf Knickung beanspruchen.The tube bundle expands as a result of the heating, while the im The tube bundle and the end chambers occurring compressive forces claim the same on kinking.

Die vorliegende Erfindung gestattet achsiale Ausdehnung und verhindert achsiale Zerknickung.The present invention permits and prevents axial expansion axial buckling.

Für diesen Zweck werden ein oder mehrere Versteifungsrohre lose zwischen festem und beweglichem Rohrboden so eingebaut, daß sie den auf den beweglichen Rohrboden wirkenden Achsialdruck aufnehmen und auf den festen Rohrboden übertragen.For this purpose, one or more stiffening tubes are loosely between Fixed and movable tube sheet installed in such a way that it fits onto the movable tube sheet absorb the acting axial pressure and transfer it to the fixed tube sheet.

Gegenüber den bereits bekannten starr mit den Rohrböden verbundenen Versteifungsrohren haben die lose eingesetzten Versteifungsrohre den Vorteil, daß diese Versteifungen unabhängig von der Ausdehnung der Wärmeaustauschrohre die Einknickung derselben verhindern.Compared to the already known rigidly connected to the tube sheets Reinforcement tubes have the loosely inserted reinforcement tubes the advantage that these stiffeners, regardless of the expansion of the heat exchange tubes, the buckling prevent the same.

Die Versteifungsrohre können sämtliche oder auch nur einen Teil der Wärmeaustauschrohre oder auch gar keine Wärmeaustauschrahre umfassen.The stiffening tubes can all or only part of the Include heat exchange tubes or no heat exchange tubes at all.

In den Versteifungsrohren der Abb. i und 2 sind Wärmeaustauschrohre angeordnet. Die Versteifungsrohre werden zweckmäßig, um einen günstigen Wärmeaustausch zu erzielen, auf der ganzen Länge oder teilweise mit Zirkulationsöffnungen versehen. Es liegen beispielsweise innerhalb des Rohres a (Abb. i und 2) mehrere Wärmeaustauschrohre, innerhalb des Rohres b (Abb. 3) zwei Wärmeaustauschrohre und innerhalb des Rohres c gar kein Wärmeaustauschrohr.In the stiffening tubes of Fig. I and 2 there are heat exchange tubes arranged. The stiffening pipes are useful for a favorable heat exchange to achieve, provided over the entire length or partially with circulation openings. For example, there are several heat exchange tubes within tube a (Fig. I and 2), inside tube b (Fig. 3) two heat exchange tubes and inside the tube c no heat exchange tube at all.

PATENTANSPRÜCHE: i. Wärmeaustauschvorrichtung mit einem festen und einem beweglichen Rohrboden, dessen Rohre gegen Knickung durch Einsatzstücke gesichert sind, dadurch gekennzeichnet, daß die in dem Rohrbündel angeordneten Versteifungsstücke von beliebigem Querschnitt lose so eingefügt sind, daß sie den auftretenden Achsialdruck aufnehmen. PATENT CLAIMS: i. Heat exchange device with a fixed and a movable tube sheet, the tubes of which are secured against kinking by insert pieces, characterized in that the stiffening pieces of any cross-section arranged in the tube bundle are loosely inserted so that they absorb the axial pressure occurring. 2. Wärmeaustauschapparat nach Anspruch i, dadurch gekennzeichnet, daß die Versteifungsstücke als durchbrochene Rohre ausgebildet und in deren Innerm Wärmeaustauschrohre angeordnet sind. 2. Heat exchange apparatus according to claim i, characterized in that the stiffening pieces are designed as perforated tubes and are arranged in the innerm heat exchange tubes.
