Description
DEUTSCHESGERMAN
Die Erfindung betrifft einen Röhrenwärmeaustauscher mit in Rohrboden wärmebeweglich eingesetzten Rohren, insbesondere mit nichtmetallischen Rohren. Bei derartigen Wärmeaustauschern ist eine Ausführungsform bekannt, bei der der Rohrboden aus zwei hintereinanderliegenden, mit Bohrungen für die hindurchgesteckten Rohrenden versehenen Platten besteht, zwischen denen sich ein Druckmittel befindet, das elastische Dichtungen aus Gummi oder gummiähnlichem Stoff an Rohr und Platten anpreßt. Es ist auch bekannt, das Druckmittel, beispielsweise Wasser, nicht nur zum Andrücken der elastischen Dichtungen, sondern auch zum Kühlen derselben zu benutzen, indem es eine niedrigere Temperatur besitzt als die Wärmeaustauschmedien und mit einer gewissen Menge den Druckmittelraum durchfließt.The invention relates to a tubular heat exchanger which is inserted in a heat-movable manner in the tube sheet Pipes, in particular with non-metallic pipes. In such heat exchangers is a Embodiment known in which the tube sheet consists of two consecutive, with holes for the there are plates with inserted pipe ends, between which there is a pressure medium, that presses elastic seals made of rubber or rubber-like material onto the pipe and plates. It is also known, the pressure medium, for example water, not only for pressing the elastic seals, but also to use it for cooling it by having a lower temperature than that Heat exchange media and flows through the pressure medium space with a certain amount.
Bei dieser Anordnung besteht eine gewisse Gefahr darin, daß der Druck des Kühlmittels beispielsweise infolge Versagens der Förderpumpe plötzlich wegfallen kann und damit nicht nur der Dichtungsdruck, sondern auch die Kühlung der wärmeempfindlichen elastischen Dichtungsmittel nicht mehr vorhanden ist. Um diese Gefahr zu vermeiden, wird nach der Erfindung für die Steuerung des Heizmittels ein besonderes Ventil benutzt, das durch den Druck des dichtenden und kühlenden Druckmittels im Rohrboden offengehalten wird. Dabei kann dieser Druck entweder nur als Impuls für eine indirekte, beispielsweise hydraulische Steuerung des Ventils für das Heizmittel dienen oder direkt den Kraftkolben des Heizmittelventils beaufschlagen.With this arrangement there is a certain risk that the pressure of the coolant, for example can suddenly drop out due to failure of the feed pump and thus not only the sealing pressure, but also the cooling of the heat-sensitive elastic sealant is no longer available. In order to avoid this risk, according to the invention, a special one is used for the control of the heating means Valve used that kept open by the pressure of the sealing and cooling pressure medium in the tube sheet will. This pressure can either only be used as a pulse for an indirect, for example hydraulic Control the valve for the heating medium or directly the power piston of the heating medium valve apply.
Die Zeichnung zeigt eine beispielsweise Ausführungsform der Erfindung. Das zur Dichtung und Kühlung dienende Druckmittel befindet sich in dem Raum 4 zwischen den beiden Platten 1 und 2 des Rohrbodens, in dem die Enden der Austauschrohre 3 mit den Dichtungen 6 abgedichtet sind. Die Dichtungen 6 sind in dem dargestellten Beispiel Platten aus Gummi oder gummiähnlichem Stoff, die an den Stellen der Rohrdurchtritte die Rohre mit kragenartigen Stulpen abdichten, die durch das Druckmittel angedrückt werden. Es können aber auch andere, beispielsweise die Rohre umgebende Einzeldichtungen verwendet werden. Das Druckmittel fließt durch die Leitung 5 zu und bei 9 ab. Das heißere der Wärmeaustauschmedien, genannt das Heizmittel, strömt bei 11 zu und bei 12 ab. In der Zuleitung zu 11 befindet sich das Ventil 13, das durch eine Stange von dem Kraftkolben 14 geöffnet bzw. geschlossen wird. Zum Schließen wirkt auf den Kolben eine Druckfeder 15. Der öffnungsdruck unter dem Kolben wird über die Verbindungsleitung 16 aus der Druckmittelleitung 5 entnommen.The drawing shows an exemplary embodiment of the invention. That about poetry and Cooling pressure medium is located in the space 4 between the two plates 1 and 2 of the Tube sheet in which the ends of the exchange tubes 3 are sealed with the seals 6. The seals 6 are plates made of rubber or rubber-like material in the example shown, which are attached to the Make the pipe penetrations seal the pipes with collar-like cuffs that are exposed to the pressure medium be pressed. However, other individual seals, for example surrounding the pipes, can also be used be used. The pressure medium flows through line 5 to and from 9. The hotter of the heat exchange media, called the heating medium, flows in at 11 and out at 12. Located in the feed line to 11 the valve 13, which is opened or closed by a rod of the power piston 14. To the Closing acts on the piston a compression spring 15. The opening pressure under the piston is about the Connecting line 16 taken from pressure medium line 5.

Versagens der Pumpe oder irrtümlichen Absperrens eines Ventils wegfällt, so schließt die Feder 15 über den Kolben 14 das Ventil 13 für das Heizmittel. Dadurch ist die Gefahr einer zu starken Erwärmung der elastischen Dichtung 6 beseitigt. Die Leitung 16 kann anstatt an die Zufuhrleitung 5 auch direkt an den Raum 4 des Druckmittels zwischen den beiden Platten 1 und 2 des Rohrbodens angeschlossen werden. An Stelle des Ventils 13 kann auch irgendein anderes Absperrorgan, beispielsweise ein Schieber oder eine Klappe, Verwendung finden, die über ein Verbindungsglied durch einen Kraftkolben oder ein entsprechendes von dem Druckmittel beaufschlagtes Organ verstellt werden.If the pump fails or a valve is accidentally shut off, the spring 15 closes over the piston 14 the valve 13 for the heating medium. This creates the risk of excessive heating of the elastic seal 6 eliminated. The line 16 can instead of the supply line 5 also directly to the Space 4 of the pressure medium can be connected between the two plates 1 and 2 of the tube sheet. Instead of the valve 13, any other shut-off device, for example a slide or a Flap, find use, which has a connecting link through a power piston or a similar one the organ acted upon by the pressure medium can be adjusted.
Die Schutzvorrichtung kann nicht nur dazu dienen, bei einem Wegfall des Druckes im Dichtungsraum des Rohrbodens die Heizmittelzufuhr vollständig abzusperren, sondern auch so eingestellt sein, daß bei absinkendem Druck des Dichtungsmittels und damit abnehmender Durchflußmenge desselben auch der Druck des Heizmittels und dessen Menge so herabgesetzt werden, daß wieder ein genügender Überdruck im Dichtungsraum und eine genügende Durchsatzmenge für die Kühlung durch das Druckmittel gegeben sind. Wesentlich für die Erfindung bleibt, daß der Impuls oder die Kraft für die Steuerung des Heizmittelventils von dem Druck des kühlenden Druckmittels im Rohrboden genommen wird.The protective device can not only serve in the event of a loss of pressure in the sealing chamber of the Tube sheet to shut off the heating medium supply completely, but also be set so that when falling Pressure of the sealant and thus, with a decreasing flow rate of the same, also the pressure of the heating medium and its amount are reduced so that again a sufficient overpressure in Sealing space and a sufficient flow rate for cooling by the pressure medium are given. It remains essential for the invention that the pulse or the force for controlling the heating medium valve is taken from the pressure of the cooling pressure medium in the tube sheet.
