Abstract
Description
Die Erfindung richtet sich auf eine Vorrichtung zum Wärmetausch, insbesondere zwischen Synthesegas- und Kesselspeisewasser, mit einer Speisewasservorwärm- und einer Dampferzeugungszone.The invention is directed to a device for heat exchange, in particular between synthesis gas and boiler feed water, with a feed water preheating zone and a steam generation zone.
Derartige Vorrichtungen werden in der Regel als sogenannte Rohrbündelwärmetauscher ausgebildet mit einem Druckbehälter, einem Rohrboden und einer Vielzahl von Rohrschlangen, die im wesentlichen U-förmig gebogen sind und deren Ein- und Austritt im gleichen Rohrboden vorgesehen ist. Bei Festbodenapparaten dagegen kommt es wegen der unterschiedlichen Temperaturen zwischen der Apparatewand und den WAT-Rohren in den Verbindungen von Rohren und Platten zu in der Regel unzulässig hohen Spannungen, was hier durch die unterschiedliche Temperaturlage in der Speisewasservorwärmzone und der Verdampferzone noch verstärkt wird. Damit verschließt sich eine derartige Vorrichtung einer Konstruktion, bei der die Wärmetauscherrohre an zwei gegenüberliegenden Rohrböden befestigt sind, d.h. bei der z.B. das Synthesegas von einer Kammer quer durch den Wärmetauscher hindurch zu einer anderen Kammer am gegenüberliegenden Ende geleitet wird und auf diesem Weg wenigstens einen Teil seiner Wärme an Wasser bzw. Dampf abgibt. Die unterschiedlichen Temperaturen würden zu ganz unterschiedlichen Ausdeh nungen der Rohre und/oder der Wand des Wärmetauschers führen, hier müssen dann insbesondere bei diesen Hochdruckapparaten entsprechende technisch aufwendige Vorkehrungen getroffen werden, un diese Spannungen und unterschiedlichen Dehungen auszugleichen.Such devices are usually designed as so-called tube bundle heat exchangers with a pressure vessel, a tube sheet and a plurality of tube coils, which are bent essentially in a U-shape and whose entry and exit is provided in the same tube sheet. In the case of fixed-floor appliances, on the other hand, because of the different temperatures between the apparatus wall and the WAT pipes in the connections of pipes and plates, there are generally inadmissibly high voltages, which is exacerbated here by the different temperatures in the feed water preheating zone and the evaporator zone. This closes such a device of a construction in which the heat exchanger tubes are fastened to two opposite tube plates, ie in which, for example, the synthesis gas is passed from one chamber across the heat exchanger to another chamber at the opposite end and in this way at least a part gives off its heat to water or steam. The different temperatures would lead to very different expansion of the pipes and / or the wall of the heat exchanger, here, in particular with these high-pressure devices, corresponding technically complex precautions must be taken to compensate for these tensions and different expansions.
Aufgabe der Erfindung ist die Schaffung einer Lösung, mit der mit vergleichsweise einfachen Mitteln erreicht wird, daß die genannten unzulässigen Spannungen vermieden werden.The object of the invention is to provide a solution with which it is achieved with comparatively simple means that the impermissible tensions mentioned are avoided.
Mit einer Vorrichtung der eingangs bezeichneten Art wird diese Aufgabe der Erfindung dadurch gelöst, daß die gasführenden Wärmetauscherrohre in zwei Festböden integriert sind, wobei das Rohrbündel im Bereich des Kesselwassereintrittes von einem den Kesselspeisewassereintritt mit umschließenden Mantel auf Abstand zur Behälterwand umgeben ist.With a device of the type mentioned, this object of the invention is achieved in that the gas-carrying heat exchanger tubes are integrated in two hard floors, the tube bundle in the area of the boiler water inlet being surrounded by a jacket feed water inlet with a surrounding jacket at a distance from the tank wall.
Mit der Erfindung wird erreicht, daß das im Prinzip kalte Kesselspeisewasser zunächst nicht die Behälterwand berührt und damit diese kühlt, sondern in der Speisewasservorwärmzone durch den Mantel von der Behälterwand abgehalten wird. Damit ist es möglich, daß sich der Ringraum zwischen Mantel und Behälterwand durch zirkulierendes Kesselwasser durchströmt wird, so daß sich eine definierte hohe Temperatur über die gesamte Länge der Behälterwand einstellt. So wird es durch die Wahl der Länge des Mantels möglich, die genanten Spannungen zu minimieren. Die Erfindung erlaubt somit, die U-Rohr-Konstruktionen zu vermeiden, die auf der Basis gleichen gasseitigen Druckverlustes doppelt so viele Rohre im Rohrboden unterbringen müssen wie der Festbodenapparat. Die Ersparnis an Wandstärken, der Behälterwände und der Rohrböden sind erheblich.With the invention it is achieved that the boiler feed water, which is in principle cold, does not initially touch the container wall and thus cool it, but is kept away from the container wall by the jacket in the feed water preheating zone. It is thus possible for circulating boiler water to flow through the annular space between the jacket and the container wall, so that a defined high temperature is established over the entire length of the container wall. So The choice of the length of the jacket makes it possible to minimize the stresses mentioned. The invention thus makes it possible to avoid the U-tube constructions which, based on the same gas-side pressure loss, have to accommodate twice as many tubes in the tube sheet as the fixed-floor apparatus. The savings in wall thicknesses, the container walls and the tube sheets are considerable.
Die Erfindung sieht auch vor, daß der Kesselspeisewassereintritt im Bereich eines Rohrbodens angeordnet und der Mantel zwischen diesem und dem Rohrboden dicht befestigt ist.The invention also provides that the boiler feed water inlet is arranged in the region of a tube sheet and the jacket is tightly fastened between the tube sheet and the tube sheet.
Wie oben bereits ausgeführt, soll mit der Erfindung erreicht werden, daß die Wandtemperatur des Druckbehälters im Bereich des Wärmetauschers möglichst gleich und hoch gehalten wird und zwar über die gesamte Länge, um die beschriebenen Belastungen zu vermeiden. In einer besonderen Ausgestaltung sieht die Erfindung daher vor, daß im Bereich des Mantels eine Zuführung für umlaufendes Kesselwasser zur Beaufschlagung des Ringraumes zwischen Behälterwand und Mantel vorgesehen ist.As already stated above, the aim of the invention is to keep the wall temperature of the pressure vessel in the area of the heat exchanger as constant and high as possible over the entire length in order to avoid the loads described. In a special embodiment, the invention therefore provides that a supply for circulating boiler water is provided in the area of the jacket to act upon the annular space between the tank wall and jacket.
Mit dieser Gestaltung ist es möglich, durch umgewälztes oder bzw. umlaufendes Kesselwasser die Wandtemperatur der Vorrichtung in diesem Bereich eben auf der Temperatur des umlaufenden Kesselwassers zu halten, wobei dies mit kon struktiv einfachen Mitteln erreichbar ist. Der Mantel dient dabei als Verteiler bzw. Leitblech für das in den Ringraum einströmende Kesselwasser, dadurch ist gewährleistet, daß die Behälterwand immer mit Kesselwasser benetzt ist, der Mantel hält das kalte eintretende Kesselspeisewasser von diesem Bereich fern.With this design it is possible to keep the wall temperature of the device in this area exactly at the temperature of the circulating boiler water by circulating or circulating boiler water, this with con structurally simple means is achievable. The jacket serves as a distributor or baffle for the boiler water flowing into the annular space, this ensures that the tank wall is always wetted with boiler water, the jacket keeps the cold incoming boiler feed water away from this area.
In Ausgestaltung sieht die Erfindung vor, daß am Mantel zwischen den gasführenden Rohrschlangen Schikanen für das Kesselspeisewasser angeordnet sind, um eine möglichst gute Führung des vorzuwärmenden Kesselspeisewassers zu erreichen.In an embodiment, the invention provides that baffles for the boiler feed water are arranged on the jacket between the gas-carrying coils in order to achieve the best possible guidance of the boiler feed water to be preheated.
Um zu verhindern, daß der Mantel auf das ihn umspülende Kesselspeisewasser abkühlend wirkt, ist vorgesehen, daß der Mantel aus einem isolierenden Material gefertigt ist. Dies ist, wie oben bereits angesprochen, zweckmäßig, um zu verhindern, daß die Temperatur des kalten Kesselspeisewassers, welches in den Mantelinnenraum eingespeist wird, das den Mantel umströmende Kesselwasser abkühlt, so daß es dann mittelbar zu einer Abkühlung der Behälterwand käme, und/oder den Wirkungsgrad des Wärmetauschers herabsetzt, was es zu verhindern gilt.In order to prevent the jacket from cooling down on the boiler feed water flowing around it, it is provided that the jacket is made of an insulating material. As already mentioned above, this is useful in order to prevent the temperature of the cold boiler feed water, which is fed into the jacket interior, from cooling the boiler water flowing around the jacket, so that the tank wall would then indirectly cool, and / or reduces the efficiency of the heat exchanger, which must be prevented.
Eine Möglichkeit nach der Erfindung, die isolierende Wirkung des Mantels zu erreichen, besteht darin, daß er in Sandwichbauweise aus einem Metallgitter zwischen zwei dün nen Blechen gebildet ist, wobei die Zwischenräume des Metallgitters mit einem Gasbeton o. dgl. ausgefüllt sind. Dabei wird die hauptisolierende Wirkung vom Gasbeton oder einer anderen keramischen Masse bewirkt, trotz der Sandwichbauweise wird durch das Ausfüllen der Hohlräume mit Gasbeton erreicht, daß der Mantel auch hohen Beanspruchungen, insbesondere Druckbeanspruchungen, stand hält.One way according to the invention to achieve the insulating effect of the jacket is that he sandwiched from a metal grid between two thin NEN sheet is formed, the spaces between the metal grid are filled with a gas concrete or the like. The main insulating effect is caused by gas concrete or another ceramic mass. Despite the sandwich construction, filling the cavities with gas concrete ensures that the jacket can withstand high loads, especially pressure loads.
Die Erfindung ist nachstehend anhand der Zeichnung beispielsweise näher erläutert. Diese zeigt in der einzigen Figur den Querschnitt durch eine Vorrichtung nach der Erfindung in vereinfachter Darstellung.The invention is explained below with reference to the drawing, for example. In the single figure, this shows the cross section through a device according to the invention in a simplified representation.
Die allgemein mit 1 bezeichnete Vorrichtung besteht aus einem Druckbehälter 2, in welchem zwei Rohrböden 3 und 4 als sogenannte Festböden eingebaut sind, an denen ein Wärmetauscherrohrbündel 5 befestigt ist. Die Festböden 3 und 4 trennen den Wärmetauscherinnenraum 6 von einer Vorkammer 7 und einer Abströmkammer 8, z.B. für Prozeßgas etwa für die Abkühlung dieses Gases aus einer Dampfreformierungssektion bzw. CO-Konvertierungssektion.The generally designated 1 device consists of a
Dem Wärmetauscherraum 6 wird kaltes, frisches Kesselspeisewasser durch einen angedeuteten Rohrstutzen 9 im Bereich des Rohrbodens 3 zugeführt. Funktionsmäßig ist dabei der Wärmetauscher in zwei Bereiche eingeteilt, nämlich eine Speisewasservorwärmzone, in der Fig. mit VZ bezeichnet, und eine Dampferzeugungszone, in der Fig. mit DZ bezeichnet.Cold, fresh boiler feed water is supplied to the
Für die Erfindung ist wesentlich, daß das Rohrbündel 5 etwa im Bereich der Vorwärmzone VZ von einem Mantel 10 umschlossen ist, der in einem Abstand zur mit 11 bezeichneten Behälterwand angeordnet ist, derart, daß sich ein Ringraum 12 bildet.It is essential for the invention that the
Wie aus der Fig. ersichtlich, wird das kalte Kesselspeisewasser über den Stutzen 9 berührungsfrei zu dem Medium, welches sich im Ringraum 12 befindet, dem Rohrbündel 5 zugeführt, so daß es in dem Bereich des Mantels 10 nicht mit der Behälterwand 11 in Berührung kommen kann. Durch in diesen Bereich eingebaute Schikanen 13 wird das Kesselspeisewasser im Kreuz/Gegenstrom zu dem die Wärmetauscherrohre 5 durchströmenden Medium geführt, was mit einem Pfeil 14 angedeutet ist.As can be seen from the FIG., The cold boiler feed water is supplied via the connector 9 without contact to the medium which is located in the
Über einen weiteren Rohrstutzen 15, der allerdings direkt in den Ringraum 12 zwischen Behälterwand 11 und Mantel 10 mündet, wird umlaufendes Kesselwasser zugeführt, derart, daß der Ringraum 12 von diesem Kesselwasser umspült wird, womit erreicht wird, daß dieser Wandbereich der Vorrichtung 1 die Temperatur des umgewälzten Kesselwassers hat. Da auch in der Dampferzeugungszone keine wesentlich anderen Bedingungen herrschen, wird erreicht, daß die Wand 11 des Druckbehälters einer vergleichsweise gleichen Temperatur über ihrer Gesamtlänge unterworfen ist. Die Kesselwassersteigrohre sind der Vollständigkeit halber noch mit 16 bezeichnet, der Prozeßgaseintrittsstutzen mit 17, der Austrittsstutzen mit 18. Im Bereich DZ vereinigen sich der Kesselwasserstrom und der erwärmte Speisewasserstrom.Circulating boiler water is supplied via a
Der Mantel 10 ist im dargestellten Beispiel im wesentlichen dreilagig ausgebildet, und zwar mit einem inneren Metalligitter 10a etwa als hexadiagonales Wabengitter, auf welches äußere Bleche 10b aufgelegt sind. Die durch das Metallgitter gebildeten Hohlräume sind mit z.B. Gasbeton ausgefüllt.In the example shown, the
Natürlich sind die beschriebenen Ausführungsbeispiele der Erfindung noch in vielfacher Hinsicht abzuändern, ohne den Grundgedanken zu verlassen. So kann die dargestellte Vorrichtung 1 auch als doppelt ausgebildeter Wärmetauscher gestaltet sein u. dgl. mehr.Of course, the described exemplary embodiments of the invention can be modified in many ways without departing from the basic idea.
