Derartige Wärmeübertrager sind aus der EP-A-0 729 772 bekannt. Sie haben sich insbesondere in der Zuckerindustrie als dampfbeheizte Eindicker bewährt.Such heat exchangers are known from EP-A-0 729 772. they have themselves Proven especially in the sugar industry as steam-heated thickeners.

Der Erfindung liegt die Aufgabe zugrunde, derartige Wärmeübertrager mit dem Ziel einer einfacheren Wartung und gegebenenfalls Reparatur sowie eines baukastenartigen Aufbaus zwecks einfacherer Anpassung an unterschiedliche Gegebenheiten und Leistungsgrößen weiterzuentwickeln.The invention has for its object to further develop such heat exchangers with the aim of easier maintenance and, if necessary, repair and a modular structure for the purpose of easier adaptation to different circumstances and output sizes.

Die Lösung dieser Aufgabenstellung ist dadurch gekennzeichnet, daß der Plattenstapel an einer das Gehäuse in einen Dampfzuführraum und einen den Plattenstapel enthaltenden Brüdenraum unterteilenden Tragwand mit Öffnungen zu den Kanälen für das andere medium befestigt ist, wobei das Gehäuse mit mindestens einem Eintrittstutzen und mindestens einem Austrittstutzen für das eine, die zwischen benachbarten Plattenpaaren gebildeten Kanäle beaufschlagende Medium versehen ist, und daß die Einzelplatten jeweils mit mindestens einer Eintrittsöffnung und mindestens einer Austrittsöffnung versehen sind, die mit den entsprechenden Öffnungen der Einzelplatten des benachbarten Plattenpaares zur Bildung von Zu- und Abströmstutzen für das andere Medium abgedichtet verbunden sind.The solution to this problem is characterized in that the plate stack is fastened to a supporting wall with openings to the channels for the other medium, dividing the housing into a steam supply space and a vapor space containing the plate stack, the housing having at least one inlet connection and at least one outlet connection for the one acting on the medium formed between adjacent pairs of plates is provided, and that the individual plates are each provided with at least one inlet opening and at least one outlet opening, which correspond to the corresponding openings in the individual plates of the adjacent plate pair to form inflow and outflow connections for the other Medium are connected in a sealed manner.

Diese erfindungsgemäße Weiterbildung der bekannten Wärmeübertrager ermöglicht auf einfache Weise die Herstellung eines den jeweiligen Gegebenheiten angepaßten Wärmeübertragers, wobei die Plattenstapel aus der jeweils benötigten Anzahl von Einzelplatten hergestellt und an der Tragwand befestigt werden, die zugleich das Gehäuse in einen Dampfzuführraum und einen den Plattenstapel enthaltenden Brüdenraum unterteilt. Das in den Kanälen zwischen benachbarten Plattenpaaren strömende Medium, beispielsweise die Zuckerlösung, wird dem Gehäuse über einen Eintrittstutzen zugeführt; der eingedickte Saft wird der Unterseite des Gehäuses durch einen Austrittstutzen entnommen. Der zur Beheizung verwendete Dampf wird über Zuströmstutzen und durch die Tragwand hindurch den Eintrittsöffnungen der zu Plattenpaaren zusammengefügten Einzelplatten zugeführt, die jeweils mit mindestens einer Austrittsöffnung versehen sind, aus denen der Restdampf bzw. das Kondensat abgezogen wird. Beim Durchströmen der Plattenstapel wird die Zuckerlösung durch den innerhalb des Plattenstapels strömenden Dampf eingedickt.

Aus der FR-A-2 523 287 war zwar ein im Kreuzstrom betriebener Plattenwärmetauscher bekannt, bei dem das beispielsweise Wärme abgebende Medium durch eine Öffnung Kanälen zugeführt wird, die voneinander durch einen weiteren Kanal getrennt sind, dem das Wärme aufnehmende Medium durch eine weitere Öffnung zugeführt wird. Jeder zweite Kanal wird somit vom Wärme abgebenden und die dazwischen liegenden Kanäle vom Wärme aufnehmenden Medium durchströmt. Hierzu ist es erforderlich, daß die Einzelplatten mit entsprechenden Stutzen versehen sind, welche verhindern, daß das jeweilige Medium in jeden Kanal einströmen kann. Das Plattenpaket des aus der FR-A-2 523 287 bekannten Plattenwärmetauschers ist von einem Gehäuse umgeben, das keinerlei medienführende Eigenschaften besitzt. Insoweit handelt es sich um einen bekannten Wärmeübertrager, nicht jedoch um einen insbesondere als dampfbeheizten Eindicker bestimmten Wärmeübertrager mit den Merkmalen der EP-A-0 729 772.From FR-A-2 523 287 was a cross-current operated Plate heat exchanger known in which, for example, the heat emitting Medium is supplied through an opening channels that are separated from one another by a are separated by another channel to which the heat absorbing medium is separated by a further opening is fed. Every second channel is therefore from the heat emitting and the intermediate channels from the heat absorbing Medium flows through. For this it is necessary that the individual plates with corresponding nozzles are provided, which prevent the respective Medium can flow into each channel. The disk package from the FR-A-2 523 287 known plate heat exchanger is of a housing surround that has no media-carrying properties. So far acts it is a known heat exchanger, but not one especially as a steam-heated thickener with the heat exchanger Features of EP-A-0 729 772.

Während die Einzelplatten zur Bildung eines Plattenpaares an ihrem Rand miteinander umlaufend verschweißt sind, ist es gemäß weiteren Merkmalen der Erfindung möglich, die Einzelplatten des Plattenstapels entweder am Rand ihrer Öffnungen miteinander zu verschweißen oder durch ausschließlich die einzelne Öffnung umgebende Dichtungen gegeneinander abzudichten, d. h. demontierbar auszuführen. Außer einem vollverschweißten Plattenstapel ist somit auch die Herstellung eines Plattenstapels möglich, dessen einzelne Plattenpaare beispielsweise zur Wartung auseinandergenommen werden können.While the individual plates to form a pair of plates at their edge with each other are welded all around, it is according to further features of the Invention possible, the individual plates of the plate stack either on the edge of their Weld openings together or by only the individual Seals around the opening to seal against each other, d. H. removable to execute. In addition to a fully welded plate stack, this is also the Production of a plate stack possible, the individual plate pairs can be taken apart for maintenance, for example.

Sofern der Wärmeübertrager als dampfbeheizter Eindicker verwendet wird, kann jede Einzelplatte gemäß einem weiteren Merkmal der Erfindung außer mindestens einer Eintrittsöffnung für den Dampf und mindestens einer Austrittsöffnung für das Kondensat mindestens eine Zusatzöffnung für den Austritt von Inertgasen aufweisen. Die Verbindung benachbarter Einzelplatten des Plattenstapels erfolgt hierbei auch bezüglich der Zusatzöffnungen entweder durch Verschweißen der Öffnungsränder oder durch ausschließlich die einzelne Öffnung umgebende Dichtungen.If the heat exchanger is used as a steam-heated thickener, each individual plate according to another feature of the invention except at least an inlet opening for the steam and at least one outlet opening for the Condensate at least one additional opening for the discharge of inert gases exhibit. The connection of adjacent individual plates of the plate stack takes place here also with respect to the additional openings either by welding the Opening edges or by only surrounding the individual opening Seals.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Einzelplatte zu beiden Plattenachsen symmetrisch ausgebildet. Hierdurch ergibt sich der Vörteil, daß der Plattenstapel aus identischen Einzelplatten hergestellt werden kann, so daß nur ein Werkzeug für die Herstellung der Einzelplatten erforderlich ist und für die Herstellung der Wärmeübertrager nur ein Plattentyp auf Lager gehalten werden muß.According to a preferred embodiment of the invention, the single plate is closed two plate axes are symmetrical. This gives the advantage that the plate stack can be made from identical individual plates, so that only one tool is required for the production of the individual plates and for the manufacture of heat exchangers only kept one type of plate in stock must become.

Bei einer bevorzugten Ausführungsform der Erfindung ist jede Einzelplatte im wesentlichen rechteckig ausgebildet und mit zwei an ihren Schmalseiten angeordneten Eintrittsöffnungen sowie in der Mitte ihrer Längsseite mit jeweils einer als Austritts- bzw. Zusatzöffnung dienenden Öffnung versehen. Durch diese erfindungsgemäße Ausbildung tritt bei dem als dampfbeheizter Eindicker eingesetzten Wärmeübertrager der Dampf von der Seite her zweiflutig in die Plattenpaare ein und kondensiert zur Mitte hin, wobei im Bereich der Mitte unten das Kondensat und oben das Inertgas aus dem jeweiligen Plattenpaar abgezogen wird.In a preferred embodiment of the invention, each individual plate is in the designed essentially rectangular and with two arranged on their narrow sides Entry openings and in the middle of their long sides with one each provided as an outlet or additional opening.

Der im Gehäuse angeordnete Plattenstapel wird bei einer bevorzugten Ausführungsform der Erfindung in senkrechter Richtung von dem dem Gehäuse über Einund Austrittstutzen zu- bzw. abgeführten Medium durchströmt. Bei einer derartigen Ausgestaltung können gemäß einem weiteren Merkmal der Erfindung mehrere Plattenstapel vorzugsweise im Abstand übereinander angeordnet werden. Während bei unmittelbar übereinander liegenden Stapeln die Brüden seitlich austreten müssen, können bei im Abstand übereinander liegenden Stapeln zusätzlich auch aus dem Raum zwischen den Stapeln Brüden austreten.The plate stack arranged in the housing is in a preferred embodiment the invention in the vertical direction from that of the housing via Einund Medium flows through the outlet port. With such a According to a further feature of the invention, several configurations Plate stacks are preferably arranged one above the other at a distance. While the stacks are directly on top of each other, the vapors are on the side must emerge, with stacks lying one above the other at a distance also leave the space between the stacks of vapors.

Um eine konstruktiv einfache Befestigung der Plattenstapel an der Tragwand zu schaffen, wird mit der Erfindung weiterhin vorgeschlagen, den oder die Plattenstapel mittels Spannelementen und einer Druckplatte zu befestigen.To ensure a structurally simple fastening of the plate stack to the supporting wall create, is further proposed with the invention, the or Fasten the plate stack using clamping elements and a pressure plate.

Wenn erfindungsgemäß in der Tragwand den Eintritts- und Austrittsöffnungen sowie gegebenenfalls Zusatzöffnungen der Einzelplatten entsprechende Öffnungen vorgesehen sind, ergibt sich eine besonders einfache Anordnung der Plattenstapel an der Tragwand, wobei die mit den Austritts- und gegebenenfalls Zusatzöffnungen korrespondierenden Öffnungen mit einer Kondensat- bzw.

Der anhand eines Ausführungsbeispieles in den Figuren 1 und 2 dargestellte Wärmeübertrager ist als dampfbeheizter Eindicker für Zuckerlösungen ausgeführt. Er besitzt ein Gehäuse 1, das beim Ausführungsbeispiel als senkrecht stehende zylindrische Trommel ausgeführt ist, die mit einer in Achsrichtung verlaufenden Tragwand 2 versehen ist, welche den Innenraum des Gehäuses 1 gemäß Fig. 2 in einen Dampfzufuhrraum 1a und einen Brüdenraum 1b unterteilt. Im Bereich des Dampfzufuhrraumes 1a ist das Gehäuse 1 mit einem Eintrittstutzen 3 für den Dampf versehen.The one shown in FIGS. 1 and 2 using an exemplary embodiment The heat exchanger is designed as a steam-heated thickener for sugar solutions. It has a housing 1, which is vertical in the exemplary embodiment standing cylindrical drum is designed with an axial direction extending support wall 2 is provided, which the interior of the housing 1 according to FIG. 2 divided into a steam supply space 1a and a vapor space 1b. In the area of the steam supply chamber 1 a, the housing 1 has an inlet connection 3 provided for the steam.

Auf der Vorderseite der Tragwand 2 sind beim Ausführungsbeispiel drei Plattenstapel 4 angeordnet, die beim Ausführungsbeispiel nach den Figuren 1 und 2 jeweils durch vier Spannelemente 5 unter Verwendung einer Druckplatte 6 befestigt sind. Die drei Plattenstapel 4 liegen im Abstand übereinander.In the exemplary embodiment, three plate stacks are on the front of the support wall 2 4 arranged, which in the embodiment of Figures 1 and 2 each by four clamping elements 5 using a pressure plate 6 are attached. The three plate stacks 4 are spaced one above the other.

Jeder Plattenstapel 4 ist aus einer Mehrzahl von Einzelplatten 7 gebildet, beispielsweise gemäß der Ausführungsform nach den Figuren 3 und 4. Bei dieser Ausführungsform ist die Einzelplatte 7 im wesentlichen rechteckig ausgebildet und mit zwei an ihren Schmalseiten angeordneten Eintrittsöffnungen 7a versehen. Weiterhin besitzt jede Einzelplatte 7 im Bereich der Mitte ihrer Längsseiten eine Austrittsöffnung 7b und eine Zusatzöffnung 7c. Wie insbesondere Fig. 3 erkennen läßt, ist die Einzelplatte 7 bezüglich ihrer Eintritts-, Austrittsund Zusatzöffnung 7a, 7b, 7c zu beiden Plattenachsen symmetrisch ausgebildet.Each plate stack 4 is formed from a plurality of individual plates 7, for example according to the embodiment of Figures 3 and 4. In this Embodiment, the single plate 7 is substantially rectangular and provided with two inlet openings 7a arranged on their narrow sides. Furthermore, each individual plate 7 has in the region of the center of its long sides an outlet opening 7b and an additional opening 7c. How in particular Fig. 3 shows, the single plate 7 is in terms of their entry, exit and Additional opening 7a, 7b, 7c formed symmetrically to both plate axes.

Auf diese Weise ist es möglich, aus zwei identischen Einzelplatten 7 ein Plattenpaar zu bilden, indem die Einzelplatten 7 sowohl an ihren Längsrändern als auch an ihren Querrändern miteinander verschweißt werden. Derartige Plattenpaare werden anschließend gemäß Fig. 4 zu einem Plattenstapel zusammengefügt, wobei jede der Öffnungen 7a, 7b und 7c von einer Dichtung 8 umgeben ist, so daß beim Zusammenfügen der Plattenstapel 4 aus aus Einzelplatten 7 gebildeten Plattenpaaren die Einzelplatten 7 benachbarter Plattenpaare gegeneinander im Bereich jeder Öffnung 7a, 7b und 7c gegeneinander abgedichtet sind.In this way it is possible to make a pair of plates from two identical individual plates 7 to form by the individual plates 7 both at their longitudinal edges can also be welded together at their transverse edges. Such plate pairs 4 are then assembled to form a stack of plates, each of the openings 7a, 7b and 7c by a seal 8 is surrounded so that when assembling the plate stack 4 from individual plates 7 formed plate pairs, the individual plates 7 of adjacent plate pairs against each other in the area of each opening 7a, 7b and 7c are sealed.

Beim Ausführungsbeispiel nach den Figuren 1 bis 4 steht jede Eintrittsöffnung 7a der Plattenstapel 4 über eine entsprechende Öffnung in der Tragwand 2 mit dem Dampfzufuhrraum 1a des Gehäuses 1 in Verbindung. Auf diese Weise tritt über den Eintrittstutzen 3 zugeführter Dampf in die Kanäle ein, die zwischen den Einzelplatten 7 jedes Plattenpaares gebildet sind. Dieser Dampf dient der Eindickung der dem Gehäuse 1 zugeführten Zuckerlösung; der Restdampf bzw. das Kondensat wird über die Austrittsöffnungen 7b (siehe Fig. 3) abgezogen, die durch eine entsprechende, in der Tragwand 2 ausgebildete Öffnung an eine Kondensatleitung 9 angeschlossen sind. Die in den Einzelplatten 7 ausgebildeten Zusatzöffnungen 7c stehen über eine entsprechende Öffnung in der Tragwand 2 mit einer Inertgasleitung 10 in Verbindung. Diese beiden Leitungen 9 und 10 sind schematisch sowohl in Fig. 1 als auch in Fig. 2 eingezeichnet.In the exemplary embodiment according to FIGS. 1 to 4, each inlet opening is located 7a of the plate stack 4 via a corresponding opening in the supporting wall 2 with the steam supply chamber 1a of the housing 1 in connection. In this way steam supplied via the inlet connection 3 enters the channels between the individual plates 7 of each pair of plates are formed. That steam serves to thicken the sugar solution supplied to the housing 1; the residual steam or the condensate is discharged through the outlet openings 7b (see FIG. 3) deducted by a corresponding, formed in the support wall 2 Opening are connected to a condensate line 9. The one in the single plates 7 formed additional openings 7c are above a corresponding opening in the support wall 2 with an inert gas line 10 in connection. These two Lines 9 and 10 are schematic both in FIG. 1 and in FIG. 2 drawn.

Die Fig. 1 zeigt weiterhin, daß die Zuckerlösung dem Brüdenraum 1b des Gehäuses 1 durch eine Zufuhrleitung 11 zugeführt wird, die in einem Saftverteiler 12 mündet. Aus der Unterseite dieses Saftverteilers 12 tritt die Zuckerlösung in Form feiner Strahlen aus, die auf die Oberseite des obersten Plattenstapels 4 auftreffen und diesen Plattenstapel von oben nach unten durch diejenigen Kanäle durchströmen, die durch benachbarte Plattenpaare gebildet werden. Beim Durchströmen des Plattenstapels 4 wird die Zuckerlösung durch den innerhalb der Plattenstapel strömenden Dampf eingedickt. Die hierbei entstehenden Brüden treten sowohl seitlich als auch oben und unten aus dem Plattenstapel 4 aus. Sie werden an der Oberseite des Gehäuses 1 durch einen Brüdenstutzen 13 abgezogen.Fig. 1 further shows that the sugar solution the vapor space 1b of the housing 1 is fed through a feed line 11 which is in a juice distributor 12 flows. The sugar solution emerges from the underside of this juice distributor 12 in the form of fine rays that hit the top of the top stack of plates 4 hit and stack this plate from top to bottom through those Flow through channels formed by adjacent plate pairs become. When flowing through the plate stack 4, the sugar solution is through the steam flowing inside the plate stack is thickened. The one here emerging vapors emerge from the side as well as above and below Plate stack 4 out. You are at the top of the housing 1 by one Vapor connector 13 deducted.

Die aus der Unterseite des obersten Plattenstapels 4 austretende, eingedickte Zuckerlösung wird aufgrund der Schwerkraft nacheinander den darunter befindlichen Plattenstapeln 4 zugeführt, so daß eine weitere Eindickung stattfindet. Der eingedickte Saft wird schließlich dem Gehäuse 1 an der Unterseite durch einen Saftstutzen 14 entnommen. The thickened emerging from the underside of the top stack of plates 4 Due to the force of gravity, sugar solution becomes the one below it Plate stacks 4 fed so that a further thickening takes place. The thickened juice is finally the housing 1 at the bottom taken through a juice nozzle 14.

Wie am besten die Fig. 1 erkennen läßt, können die übereinander an der Tragwand 2 befestigten Plattenstapel 4 insbesondere zur Reinigung ihrer mit der Zuckerlösung beaufschlagter Kanäle von der Tragwand 2 abgenommen werden, indem die beim Ausführungsbeispiel als Spannschrauben ausgebildeten Spannelemente 5 gelöst und die Druckplatten 6 entfernt werden, so daß die Plattenstapel 4 von der Tragwand 2 entfernt werden können. Da beim Ausführungsbeispiel nach den Figuren 3 und 4 die einzelnen Plattenpaare ausschließlich mit Hilfe der Spannelemente 5 und der Druckplatte 6 abgedichtet zusammengehalten werden, ist eine Demontage der einzelnen Plattenstapel 4 in Plattenpaare möglich, so daß die von der Zuckerlösung beaufschlagten Kanäle problemlos gereinigt werden können.As best seen in Fig. 1, the one above the other Supporting wall 2 attached plate stack 4 in particular for cleaning them with the sugar solution loaded channels removed from the support wall 2 are formed by the clamping screws in the exemplary embodiment Clamping elements 5 released and the pressure plates 6 removed, so that the plate stack 4 can be removed from the support wall 2. Since at Embodiment according to Figures 3 and 4, the individual plate pairs exclusively sealed with the help of the clamping elements 5 and the pressure plate 6 are held together is a disassembly of the individual plate stacks 4 possible in pairs of plates, so that the channels acted upon by the sugar solution can be easily cleaned.

Bei dem in den Figuren 5 und 6 dargestellten Ausführungsbeispiel werden die wiederum rechteckigen und hinsichtlich ihrer Eintritts-, Austritts- und Zusatzöffnungen 7a, 7b, 7c zu beiden Plattenachsen symmetrisch ausgebildeten Einzelplatten 7 über den gesamten Umfang zu Plattenpaaren verschweißt. Bei diesem Ausführungsbeispiel werden benachbarte Einzelplatten 7 des Plattenstapels 4 im Bereich ihrer Öffnungen 7a, 7b und 7c miteinander verschweißt, wie die Schweißnähte 15 in Fig. 6 erkennen lassen. Die Fig. 5 zeigt, daß bei diesem Ausführungsbeispiel einer Einzelplatte 7 die Eintrittsöffnung 7a für den Dampf mittig und die Austrittsöffnung 7b für das Kondensat sowie die Zusatzöffnung 7c für die Inertgase paarweise an der Schmalseite der rechtekkigen Einzelplatte 7 ausgebildet sind.In the embodiment shown in Figures 5 and 6, the again rectangular and with regard to their inlet, outlet and additional openings 7a, 7b, 7c formed symmetrically to both plate axes Individual plates 7 welded to plate pairs over the entire circumference. At In this embodiment, adjacent individual plates 7 of the plate stack 4 welded together in the area of their openings 7a, 7b and 7c, how the welds 15 in Fig. 6 can be seen. Fig. 5 shows that at this embodiment of a single plate 7 for 7a the steam in the middle and the outlet opening 7b for the condensate and the Additional opening 7c for the inert gases in pairs on the narrow side of the rectangular one Single plate 7 are formed.

Die in den Figuren 5 und 6 dargestellte Ausführung ergibt somit Plattenstapel 4 aus vollverschweißten Einzelplatten 7, die jedoch ebenso wie die Plattenstapel 4 aus den in den Figuren 3 und 4 dargestellten Einzelplatten 7 von der Tragwand 2 abgenommen und außerhalb des Gehäuses 1 gereinigt werden können.The embodiment shown in FIGS. 5 and 6 thus results in a stack of plates 4 from fully welded individual plates 7, which, however, just like the plate stack 4 from the individual plates 7 shown in FIGS. 3 and 4 from the Support wall 2 removed and cleaned outside of the housing 1 can.

Die in Fig. 7 dargestellte dritte Ausführungsform einer Einzelplatte 7 zeigt eine dem ersten Ausführungsbeispiel nach den Figuren 3 und 4 ähnliche Ausbildung. Auch hier werden die Öffnungen 7a, 7b und 7c der Einzelplatten 7 benachbarter Plattenpaare durch Dichtungen 8 gegenüber den von der Zuckerlösung durchströmten Kanälen abgedichtet, wenn die Plattenpaare mit Hilfe der Spannelemente 5 und der Druckplatte 6 lösbar an der Tragwand 2 befestigt werden. Die Fig. 7 zeigt, daß es bei dieser Ausführungsform möglich ist, innerhalb der Eintrittsöffnungen 7a Führungslöcher 7d in den Einzelplatten 7 auszubilden. Mit diesen Führungslöchern 7d werden die zu Plattenpaaren verschweißten Einzelplatten 7 auf die Spannelemente 5 aufgefädelt, so daß diese Spannelemente 5 zugleich als Führungen für die Einzelplatten 7 dienen, wenn diese lösbar an der Tragwand 2 befestigt werden. The third embodiment of a single plate 7 shown in FIG. 7 shows one the first embodiment of Figures 3 and 4 similar training. Here, too, the openings 7a, 7b and 7c of the individual plates 7 become more adjacent Plate pairs through seals 8 compared to that of the sugar solution flowed through channels sealed when the plate pairs using the Clamping elements 5 and the pressure plate 6 releasably attached to the support wall 2 become. Fig. 7 shows that it is possible in this embodiment, inside of the inlet openings 7a, guide holes 7d in the individual plates 7 to train. These guide holes 7d are used to weld the plate pairs Individual plates 7 threaded onto the clamping elements 5 so that they Clamping elements 5 also serve as guides for the individual plates 7 when these are releasably attached to the support wall 2.
