Abstract
Description
Die Erfindung betrifft einen Rohrbündelwärmeaustauscher mit Rohrböden aus Kunststoff, in die gegebenenfalls eine Metallplatte eingelegt ist und in denen die Rohre in Bohrungen angeordnet und jeweils mit Hilfe einer das Rohr umgebenen Dichtung eingedichtet sind.The invention relates to a tube bundle heat exchanger with tube plates made of plastic, in which optionally a metal plate is inserted and in which the tubes are arranged in bores and sealed in each case by means of a pipe surrounding the seal.
Wärmetauscher für den hochkorrosiven Einsatz werden heutzutage aus Materialien wie Glas, Graphit, PTFE oder Siliziumcarbid für die Rohre bzw. Glas, Email- oder PTFE-Auskleidungen für Stutzen, Verteilerraum und Mantelraum hergestellt.Nowadays, heat exchangers for highly corrosive applications are manufactured from materials such as glass, graphite, PTFE or silicon carbide for the pipes or glass, enamel or PTFE linings for nozzles, distributor space and jacket space.
Im Gegensatz zu herkömmlichen Wärmeaustauschern aus Metall, bei denen die Rohre mit den Rohrböden durch Einlöten, Schweißen oder Bördeln verbunden sind, ist dieses bei Einsatz von Glas- oder Siliziumcarbidrohren nicht möglich. Hierzu werden aufwendige Systeme zur Abdichtung benötigt. Insbesondere führt die vertikale Ausdehnung und die Kontraktion der Heizrohre zu Problemen.Unlike conventional heat exchangers made of metal, in which the tubes are connected to the tubesheets by soldering, welding or crimping, this is not possible when using glass or silicon carbide tubes. For this purpose, complex systems are required for sealing. In particular, the vertical expansion and the contraction of the heating pipes leads to problems.

Der Nachteil hieran ist, daß die beiden Rohrböden mit Fasen an den Durchgangsbohrungen ausgeführt sind und der O-Ring sich nicht stopfbuchsenartig verpressen läßt.The disadvantage of this is that the two tubesheets are designed with chamfers on the through holes and the O-ring can not compress stuffing box.

Die vorbekannten Lösungen haben den Nachteil, daß sie einen konstruktiv hohen Aufwand erfordern und dabei auch zeitaufwendig für die Montage der Wärmeaustauscher sind.The previously known solutions have the disadvantage that they require a constructively high effort and are also time-consuming for the installation of the heat exchanger.
Aufgabenstellung task
Die Aufgabe der Erfindung liegt darin, daß bei einem Rohrbündelwärmeaustauscher der eingangs genannten Art die Abdichtung der Rohre, vorzugsweise SiC-Rohre, in den zweigeteilten Rohrböden weiter zu verbessern, wobei eine Abdichtung nach dem Stopfbuchsenprinzip ermöglicht werden soll.The object of the invention is that in a shell-and-tube heat exchanger of the type mentioned, the sealing of the tubes, preferably SiC tubes, in the two-part tube plates to further improve, with a seal according to the stuffing box principle to be made possible.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die beiden Rohrbodenplatten baugleich ausgeführt sind und zwischen diesen eine Zwischenplatte angeordnet ist, diese mit Durchgangsbohrungen zur Aufnahme der Rohre versehen sind, wobei die Durchgangsbohrungen in der Zwischenplatte größer als die Durchgangsbohrungen in den Rohrbodenplatten ausgebildet und in diese Compoundhülsen einsetzbar sind. Die Compoundhülsen sind mit einer Bohrung und diese an ihren Endbereichen mit einer konusförmigen Erweiterung versehen.According to the invention the object is achieved in that the two tubesheet plates are designed to be identical and between them an intermediate plate is arranged, they are provided with through holes for receiving the tubes, wherein the through holes formed in the intermediate plate larger than the through holes in the tubesheet plates and in these compound sleeves can be used. The compound sleeves are provided with a bore and this at their end with a cone-shaped extension.
Durch die Compoundhülsen wird das Rohr, vorzugsweise ein SiC-Rohr, hindurchgeführt, wodurch sich auf beiden Seiten ein konusförmiger Raum zur Aufnahme einer Dichtung ergibt. Die Dichtungen sind in Form eines Dichtringes mit quadratischem, rechteckigem, trapezförmigem, rundem oder ovalem Querschnitt ausgebildet.Through the compound sleeves, the tube, preferably a SiC tube, passed through, resulting in a conical space for receiving a seal on both sides. The seals are in the form of a sealing ring with square, rectangular, trapezoidal, round or oval cross-section.
Bei der Montage des Rohrbündelwärmeaustauschers werden die Bodenplatten mit der Zwischenplatte und den eingesetzten Rohren zwischen Mantel- und Haubenflansch eingesetzt. Bei der abschließenden Verschraubung werden die Platten zusammengepreßt. Durch die Pressung werden die Dichtungen in den konusförmigen Raum stopfbuchsenartig eingeprellt und somit die Dichtheit der SiC-Rohre gegenüber den Rohrbodenplatten hergestellt.When mounting the tube bundle heat exchanger, the bottom plates with the intermediate plate and the tubes inserted between the jacket and hood flange are used. At the final screwing the plates are pressed together. As a result of the pressure, the gaskets are crimped into the cone-shaped space in the manner of a gland, thus producing the tightness of the SiC pipes in relation to the tubesheet plates.
Die Tiefe der konusförmigen Erweiterung ist derart ausgeführt, daß bei eingepreßter Dichtung ein Restraum ergibt, der zur Aufnahme von Quell- und/oder Wärmedehnungsvolumina der Dichtung dient.The depth of the cone-shaped extension is designed so that when pressed seal results in a residual space, which serves to accommodate the swelling and / or thermal expansion of the seal.
Durch die Ausführung der konusförmigen Erweiterung auf beiden Seiten der Compoundhülse zur Aufnahme der Dichtungen wird gewährleistet, daß diese immer mehr oder weniger gepreßt werden und sich so das Dichtverhalten verbessert.By carrying out the conical enlargement on both sides of the compound sleeve for receiving the seals ensures that these are always more or less pressed and thus improves the sealing behavior.
