Drossel für WärmeaustauscherThrottle for heat exchanger

Die Erfindung betrifft Drosseln zur Erzeugung eines Druckverlustes in einem //ärmeaustauscher, welche in Sammler oder j Lochplatten der Mediumzuführung eingebaut sind.The invention relates to throttles for generating a pressure loss in a // heat exchanger, which is in collector or j Perforated plates of the medium supply are installed.

Der "Vorgang der Drosselung in Rohren von Wärmetauschern und Dampferzeugern ist allgemein bekannt. Häufig werden hierfür Ringdrosseln verwendet, welche in die Rohre eingeschweißt werden. Bei geringen Wandstärken und Durchmessern der Rohre, wie sie beispielsweise bei Wärmeaustauschern für Kernreaktoren auftreten, ist das übliche Einschweißen der erwähnten Ringdrosseln oder Ringblenden nicht möglich, weil die Schweißstellen nicht mehr so gut zugänglich sind, um eine gute Verarbeitung zu gewährleisten. Pur derartige Fälle sind bereits einsteckbare Drosseln bekannt, welche in Rohre eingesteckt sind. IThe "process of throttling in tubes of heat exchangers and Steam generators is well known. Often ring throttles are used for this, which are welded into the pipes will. With small wall thicknesses and diameters of the tubes, such as those used in heat exchangers for nuclear reactors occur, the usual welding of the aforementioned annular throttles or annular diaphragms is not possible because the welds are no longer so easily accessible in order to guarantee good workmanship. There are already such cases insertable chokes known which are inserted into pipes. I.

Es ist bereits eine einsteckbare Drossel bekannt (US-Patentschrift 2 664 109)» welche aus mehreren Elementen besteht und in die, zu drosselnde Leitung eingesetzt ist. Jedoch sind diese einzelnen Elemente der Drossel fertigungstechnisch sehr aufwendig und entsprechen nicht immer den gestellten Anforderungen. Dies trifft insbesondere für Wärmeaustauscher zu, die nach dem Prinzip -des Zwangsdurchlaufkesseis arbeiten. Hierbei liegt der Nenndurohsatz bei verschiedenen Lasten im instabilen Bereich, so daß die MengenA plug-in throttle is already known (US patent specification 2 664 109) »which consists of several elements and is inserted into the line to be throttled. However these individual elements of the throttle are very complex to manufacture and do not always correspond to those provided Requirements. This is especially true for heat exchangers that operate on the principle of forced flow boiler work. Here, the nominal flow rate is different Loads in the unstable area, so the quantities

des Arbeitsmedium^ in den einzelnen Rohren unzulässige Abweichungen voneinander haben wurden.of the working medium ^ inadmissible in the individual pipes There have been deviations from each other.

Die Erfindung hat es sich zur Aufgabe gemacht, Drosseln zur Erzielung einer stabilen Strömung zu schaffen, in welcher weder bleibende noch periodische, Durchsatzabweichungen auftreten. Es müssen daher in die Eintrittsrohre Drosseln mit einem bestimmten Druckverlust bei Vollast eingebaut werden. Die Lösung der gestellten Aufgabe besteht darin, daß die einsteckbare Drossel stufenartig ausgebildet ist. mit Trennwänden und jeweils um 180 Winkelgrade am Umfang der Trennwände vorsetzt zueinan- der liegenden Einfräsungen. Eine derartige Ausbildung der Rohrdrossel gewährleistet, wie sich aus Versuchen ergeben hat, einen bestimmten Druckverlust und ist auch nicht so störanfällig gegen Verschmutzung, wie dies von anderen Bauarten einsteckbarer Drosseln her bekannt ist»The invention has set itself the task of creating throttles to achieve a stable flow, in which neither permanent nor periodic, throughput deviations occur. There must therefore be throttles with a certain pressure loss in the inlet pipes To be installed at full load. The solution to the problem is that the insertable throttle is stepped is trained. with dividing walls and each facing each other by 180 degrees on the circumference of the dividing walls lying millings. Such a design of the pipe throttle ensures, as shown by tests has a certain pressure loss and is not as susceptible to pollution as other types plug-in chokes is known »

in mehrere Kammern 3 unterteilt ist. Diese Kammern sind durch _jinfr3Düngen 4 miteinander verbunden, die am Umfnnö der Trennwände 2 so angeordnet sind, daß sie je-'.'cils um 130 V/inkelgrade versetzt in i3ezuo auf dio n.ichfclgende Kammer liegen. Durch diese Ausbildungsform -:ird ein optimaler Druckabfall erreicht, da des durchströmende /..edium nacheinander die einzelnen Kammern 3 passiert und dabei durch die versetzt angeordneter. Einfrr'sungen 4 mehrere Umlenkungen erfährt.is divided into several chambers 3. These chambers are interconnected by _jinfr3Düngen 4, which are on the partition walls 2 Umfnn ö arranged so that they each - are cils 130 V / inkelgrade offset in i3ezu o on dio n.ichfclgende chamber '.'. With this form of embodiment, an optimal pressure drop is achieved, since the medium flowing through passes through the individual chambers 3 one after the other and through the staggered ones. Einfrrr'sungen 4 experiences several diversions.

Die Drossel 1 v/eist am-Eintritt einen Ansatz 5 auf, so daß sie, wie aus den Fig. 5 und 6 zu ersehen ist, an dem Rohr 11 anliegt. Pur die Befestigung der Drosseln ist ein 3-ev/indezapfen 6 vorgesehen, welcher gemäß den Pig. 5 und 6 in der Prallplatte 7 durch eine Kutter S gehalten wird. Stattdessen kann das ^ev.inde des G-ewindezapfens auch direkt in eine (Jev.1 indebohrung der Prallplatte 7 eingedreht sein.The throttle 1 v / eist an extension 5 at the inlet, so that, as can be seen from FIGS. 5 and 6, it rests against the pipe 11. A 3-ev / indezapfen 6 is provided for the attachment of the throttles, which according to the Pig. 5 and 6 is held in the baffle plate 7 by a cutter S. Instead, the thread pin can also be screwed directly into a Jev. 1 hole in the baffle plate 7.

In Pig. 3 ist eine andere AusfUhrunjsform der Drossel gezeigt, wobei unmittelbar kammer art ige Einfräsungeii 4' in wechselnder Höhenlage vorgesehen sind, die durch Bohrungen 9 miteinander verbunden sind. Diese Ausführung ist besonders wirtschaftlich in fertigungstechnischer Hinsicht, da bei der Herstellung nur einfache Arbeitsgänge auszuführen sind.In Pig. 3 shows another embodiment of the throttle, where immediately chamber-like milling egg 4 'in alternating Elevation are provided, which are connected to one another by holes 9. This design is particularly economical in terms of manufacturing technology, since only during manufacture simple operations are to be carried out.

In Pig. 5 ist eine Drossel der erfindungsgemäßen Art - wie in Pig. 1 gezeigt - in den Rohrboden 10 eines Wärmetauschers eingebaut gezeigt. Aus. Pig. 6 ist die in Pig. 3 gezeigte Drossel ebenfalls in eingebautem Zustand erkennbar. Die Drosseln 1 sind in die Rohre 11 eingesetzt, welche in dem Rohrboden 10 angeordnet sind. Die Halterung der Drosseln erfolgt mittels der Irdllplatte 7, die durch Stiftschrauben 12 auf dem Rohrboden befestigt ist. Das Medium tritt in Pfeilrichtung durch Strömungslöcher 13 in den Raum zwischen der Prallplatte 7 und dem Rohrboden 10 und gelangt sodann durch die Einfräsung 4 am Ansatz 5 in die erste Kammer, von wo es nach einer Umlenkung In Pig. 5 is a choke of the type according to the invention - as in Pig. 1 - shown installed in the tube sheet 10 of a heat exchanger. The end. Pig. 6 is the one in Pig. 3 shown throttle can also be seen in the installed state. The reactors 1 are inserted into the tubes 1 1, which are arranged in the tubesheet 10th The throttles are held by means of the Irdllplatte 7, which is fastened by studs 12 on the tube sheet. The medium enters the space between the baffle plate 7 and the tube sheet 10 in the direction of the arrow through flow holes 13 and then passes through the milled recess 4 at the attachment 5 into the first chamber, from where it is deflected

die weiteren Kammern passiert und dabei mehrmals umgelenkt wird.the other chambers passed and redirected several times will.

¥±ß. 7 zeigt dann einen Teil einer in der Praxis .verwirklichten Anlage, in der die erfindungsgemäßen Drosseln eingesetzt worden sind. Es handelt sich um den Speisewassereintrittsstutzen für einen Wärmetauscher, v/ie sie beispielsweise in Kernreaktoren Verwendung finden. Die Drosseln 1 sind in die Lochplatte 10 eingesetzt. Das Speisewasser strömt dabei durch den Kanal 14 ein und dringt durch die mit Bohrungen versehene Prallplatte.in die Drosseln ein. ¥ ± ß. 7 then shows part of a system which has been implemented in practice and in which the throttles according to the invention have been used. It is the feed water inlet connection for a heat exchanger, which is used, for example, in nuclear reactors. The throttles 1 are inserted into the perforated plate 10. The feed water flows in through the channel 14 and penetrates the throttles through the baffle plate provided with holes.

Die erfindungsgemäßen Drosseln zeichnen sich auch noch dadurch aus, daß sie in einfacher Weise entfernt oder ausgetauscht werden können.The chokes according to the invention are also distinguished by this from that they can be easily removed or replaced.

Außerdem können die Druckverluste in ein und derselben Anlage in einfacher \7eise dadurch variiert werden, daß Drosseln gleicher Bauart, jedoch mit einer mehr oder weniger großen Anzahl von Kammern oder Trennwänden eingebaut werden. Es ist also auf einfache .'/eise durch den Einbau unterschiedlich langer Drosseln möglich, unterschiedliche Druckverluste in den Rohren eines Dampferzeugers oder Wärmetauschers auszugleichen.In addition, the pressure losses in one and the same system can be varied in a simple manner by using throttles of the same design, but with a more or less large number of chambers or partitions. It is in other words, in a simple way, thanks to the installation of different lengths Throttles possible to compensate for different pressure losses in the pipes of a steam generator or heat exchanger.
