Description

Die Erfindung betrifft eine Kondensationsanlage mit den Merkmalen im Oberbegriff des Patentanspruchs 1.The invention relates to a condensation plant having the features in the preamble of patent claim 1.

Insbesondere bei größeren Kraftwerkseinheiten und bei Gebäuden im unmittelbaren Nahbereich luftgekühlter Kondensationsanlagen muss bei ungünstigen Windverhältnissen zum Teil mit deutlicher Warmluftrezirkulation gerechnet werden. Die Warmluftrezirkulation findet in begrenzten Bereichen, insbesondere in den Eckbereichen einer Kondensationsanlage statt. Die naheliegendste Lösung wäre es, die Höhe der die Wärmetauscherelemente umgebenden Windschutzwände zu erhöhen. Grundsätzlich wäre dies nur in den kritischen Bereichen erforderlich. Kostengründe, die Statik der Kondensationsanlage sowie Umweltauflagen und wechselnde Intensitäten der Warmluftrezirkulation sprechen jedoch gegen diese Vorgehensweise und verlangen nach einer kostengünstigeren und effektiven Maßnahme, um auch temporär, das heißt nur bei konkretem Vorliegen des tatsächlichen Problems die Warmluftrezirkulation zu verringern.Especially with larger power plant units and buildings in the immediate vicinity of air-cooled condensation systems must be expected in unfavorable wind conditions partly with significant warm air recirculation. The warm air recirculation takes place in limited areas, especially in the corner areas of a condensation plant. The most obvious solution would be to increase the height of the windbreak walls surrounding the heat exchanger elements. Basically, this would only be necessary in the critical areas. Cost reasons, the statics of the condensation plant and environmental requirements and changing intensities of warm air recirculation speak against this approach and call for a more cost-effective and effective measure to temporarily, that is to reduce only in the actual existence of the actual problem, the hot air recirculation.

In der DE 34 21 200 A1 wird zur Reduzierung der Warmluftrezirkulation eine zwangsbelüftete Kondensationsanlage mit einer aerodynamischen Wand vorgeschlagen. Die Strömungsgeschwindigkeit der aerodynamischen Wand soll höher sein als die Austrittsgeschwindigkeit der Kühlluft aus den Wärmetauscherelementen. Hierbei wird auf die leicht bauenden Windschutzwände verzichtet und stattdessen eine relativ großvolumige Düsenanordnung vorgeschlagen, wobei die Düsen oberhalb oder seitlich der Wärmetauscherelemente angeordnet sein können. Es sind auch besonders ausgestaltete Schlitzdüsen denkbar, welche an dem Rand der Kondensationsanlage angeordnet werden und die mit kalter oder auch mit warmer Luft beschickt werden können.In the DE 34 21 200 A1 In order to reduce the warm air recirculation, a forced-ventilation condensation system with an aerodynamic wall is proposed. The flow velocity of the aerodynamic wall should be higher than the exit velocity of the cooling air from the heat exchanger elements. Here is dispensed with the easy-to-build wind walls and instead proposed a relatively large-volume nozzle assembly, the nozzles can be arranged above or to the side of the heat exchanger elements. There are also particularly designed slot nozzles conceivable, which are arranged at the edge of the condensation plant and which can be charged with cold or hot air.

Da das Problem der Warmluftrezirkulation stark von der vorherrschenden Windrichtung und den lokalen Windgeschwindigkeiten abhängig ist, stellt eine ausschließlich als aerodynamische Wand ausgebildete Barriere einen hohen apparativen Aufwand dar, der keineswegs an allen Randbereichen einer Kondensationsanlage zwingend erforderlich ist. Auch wenn es grundsätzlich möglich ist, einen Teil des Randbereichs der Kondensationsanlage mit einer aerodynamischen Wand zu versehen, ist es aufgrund der Änderung der Windverhältnisse schwierig vorherzusehen, ob nicht temporär auch andere Abschnitte des Randbereichs von erhöhter Warmluftrezirkulation betroffen sind. Ein schnelles Umrüsten ist in einem solchen Fall nicht möglich. Vorsorglich müsste man den gesamten Randbereich mit einer aerodynamischen Wand ausrüsten, was allerdings aus Kostengründen nicht sinnvoll ist.Since the problem of warm air recirculation is highly dependent on the prevailing wind direction and the local wind speeds, a barrier formed exclusively as an aerodynamic wall represents a high expenditure on equipment, which is by no means compulsorily required on all marginal areas of a condensation plant. Although it is basically possible to provide a part of the edge region of the condensation plant with an aerodynamic wall, it is difficult to predict due to the change in wind conditions, whether temporarily not other sections of the edge area are affected by increased warm air recirculation. Fast conversion is not possible in such a case. As a precaution, you would have to equip the entire edge area with an aerodynamic wall, which, however, does not make sense for cost reasons.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Kondensationsanlage mit einer aerodynamischen Wand bereitzustellen, die ohne große bauliche Veränderungen im Bedarfsfall zumindest bereichsweise zuschaltbar ist.Proceeding from this, the present invention seeks to provide a condensation plant with an aerodynamic wall, which is at least partially switchable without major structural changes in case of need.

Diese Aufgabe ist bei einer Kondensationsanlage mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved in a condensation plant with the features of claim 1.

Vorteilhafte Weiterbildungen des Erfindungsgedankens sind Gegenstand der Unteransprüche.Advantageous developments of the inventive concept are the subject of the dependent claims.

Die erfindungsgemäße Kondensationsanlage weist an ihrem Rand eine aus Plattenelementen aufgebaute Windschutzwand auf, wobei die Plattenelemente eine Vielzahl von sich in Hochrichtung erstreckenden Hohlkammern aufweisen. Die Hohlkammern dieser Windschutzwand werden dafür genutzt, einen Luftstrom zur Schaffung einer aerodynamischen Wand oberhalb der Windschutzwand auszubilden. Der wesentliche Vorteil der erfindungsgemäßen Kondensationsanlage ist, dass keine zusätzlichen Schlitzdüsen oder aufwendige Düsenschächte installiert werden müssen, da die ohnehin vorhandene Windschutzwand zur Ausbildung einer aerodynamischen Wand genutzt wird.The condensation plant according to the invention has at its edge a windbreak wall constructed from plate elements, wherein the plate elements have a multiplicity of hollow chambers extending in the vertical direction. The hollow chambers of this windbreak wall are used to form an air flow to create an aerodynamic wall above the windbreak wall. The essential advantage of the condensation plant according to the invention is that no additional slot nozzles or complex nozzle shafts must be installed, since the already existing windbreak wall is used to form an aerodynamic wall.

Der eingeleitete Luftstrom ist insbesondere ein Kaltluftstrom, der sich mit der erwärmten Kühlluft vermengt und allein aufgrund der Vermengung die negativen Auswirkungen der verbleibenden Warmluftzirkulation mindert. Numerische Überprüfungen ergaben bei geeigneten Geschwindigkeiten des Luftstroms eine deutliche Reduzierung der lokalen Warmluftrezirkulationsrate um einige Prozentpunkte. Dies führt zu einer Verbesserung der Kondensationsleistung und damit zu einer Steigerung des Kraftwerkwirkungsgrads. Die Förderung des beschleunigten Luftstroms kann mit einem separaten, z.B. mit einem mobilen Gebläse erfolgen oder auch durch Abzweigen eines Teilstroms von den Kühlluft fördernden Ventilatoren, welche den randseitigen Wärmetauscherelementen zugeordnet sind. Aufgrund des relativ geringen Querschnitts der Hohlkammern würde zwar ein Druckverlust entstehen, allerdings ist die Förderleistung der Ventilatoren sehr hoch, so dass der Volumenstrom im Bereich der aerodynamischen Windwand relativ hoch ist und die Druckverluste kompensiert. Durch Nutzung der vorhandenen Windschutzwände lässt sich temporär und auch dauerhaft eine flexible und gleichzeitig effektive Lösung zur Reduzierung der Warmluftrezirkulation mit relativ geringem technischem Aufwand und auch mit geringen Kosten erreichen.The introduced air flow is in particular a cold air flow, which mixes with the heated cooling air and alone due to the mixing reduces the negative effects of the remaining warm air circulation. Numerical checks showed a significant reduction of the local warm air recirculation rate by a few percentage points at suitable air flow rates. This leads to an improvement in the condensation performance and thus to an increase in power plant efficiency. The promotion of the accelerated air flow can be accomplished with a separate, e.g. be done with a mobile fan or by branching a partial flow of the cooling air-promoting fans, which are associated with the peripheral heat exchanger elements. Although due to the relatively small cross section of the hollow chambers, a pressure loss would occur, however, the delivery rate of the fans is very high, so that the volume flow in the aerodynamic wind wall is relatively high and compensates the pressure losses. By using the existing wind walls can be temporarily and permanently a flexible and effective solution to reduce warm air recirculation with relatively little technical effort and also achieve low costs.

Die Erfindung wird nachfolgend anhand der in den Zeichnungen dargestellten Ausführungsbeispiele näher erläutert. Es zeigen:

The invention will be explained in more detail with reference to the embodiments illustrated in the drawings. Show it:

in the side view of a condensation plant with a plurality of roof-shaped heat exchanger elements arranged in series, which are positioned between marginal windshields;
FIG. 2

Die Figuren 1 und 2 zeigen eine Kondensationsanlage 1 mit mehreren in Reihe angeordneten Wärmetauscherelementen 2, denen über Ventilatoren 3 Kühlluft K zugeführt wird. Dadurch kondensiert der über eine Dampfverteilleitung 4 zugeführte Wasserdampf innerhalb der Wärmetauscherelemente 2. Die Wärmetauscherelemente 2 sind insgesamt von einer am Rand 5 der Kondensationsanlage 1 angeordneten Windschutzwand 6 umgeben, die eine sofortige und ungehinderte Warmluftrezirkulation verhindert. Der Grad der Warmluftrezirkulation ist stark abhängig von der lokal vorherrschenden Windrichtung. Insbesondere im Eckbereich einer Kondensationsanlage kann es zu starker Warmluftrezirkulation kommen, welche die Kondensationsleistung und damit den Kraftwerkwirkungsgrad negativ beeinflusst. Im Rahmen der Erfindung ist vorgesehen, dass oberhalb der Windschutzwand 6 eine aerodynamische Wand 7 ausgebildet wird, die eine zusätzliche Barriere zwischen der aus den Wärmetauscherelementen 2 abströmenden Warmluft W und der von unten angesaugten Kühlluft K darstellt. In Figur 1 ist beispielhaft eingezeichnet, dass lediglich im Bereich der in der Bildebene linken Windschutzwand 6 eine solche aerodynamische Wand 7 ausgebildet ist. Entsprechende Randabschnitte 8 einer aerodynamischen Wand 7 sind ebenso beispielhaft in der Draufsicht der Figur 2 eingezeichnet. Eine solche aerodynamische Wand ist in der Regel nur lokal erforderlich, insbesondere wenn ganz bestimmte Windverhältnisse vorherrschen. Entscheidend ist, dass die aerodynamische Wand 7 an jedem beliebigen Randabschnitt 8 ausgebildet werden kann, ohne dass wesentliche bauliche Veränderungen an der Kondensationsanlage erforderlich sind.The Figures 1 and 2 show a condensation plant 1 with several arranged in series heat exchanger elements 2, which is supplied via fans 3 cooling air K. As a result, the water vapor supplied via a steam distribution line 4 condenses within the heat exchanger elements 2. The heat exchanger elements 2 are surrounded overall by a windbreak wall 6 arranged on the edge 5 of the condensation plant 1, which prevents immediate and unhindered warm air recirculation. The degree of warm air recirculation is highly dependent on the locally prevailing wind direction. In particular, in the corner region of a condensation plant, there may be strong warm air recirculation, which negatively affects the condensation performance and thus the power plant efficiency. In the context of the invention, it is provided that an aerodynamic wall 7 is formed above the windbreak wall 6, which constitutes an additional barrier between the hot air W flowing out of the heat exchanger elements 2 and the cooling air K drawn in from below. In FIG. 1 By way of example, it is shown that such an aerodynamic wall 7 is formed only in the area of the windscreen wall 6 left in the image plane. Corresponding edge portions 8 of an aerodynamic wall 7 are also exemplary in the plan view of FIG. 2 located. Such an aerodynamic wall is usually only local necessary, especially if very specific wind conditions prevail. It is crucial that the aerodynamic wall 7 can be formed at any desired edge portion 8, without significant structural changes to the condensation plant are required.

Der zur Ausbildung einer aerodynamischen Wand 7 erforderliche Luftstrom L wird durch Hohlkammern 9 der Windschutzwand 6 geführt. In diesem Ausführungsbeispiel sind die Hohlkammern 9 trapezförmig konfiguriert (Figur 5). Windschutzwände 6 können insbesondere aus selbsttragenden Plattenelementen errichtet werden, die z.B. eine Trapez- oder Wellenform haben. Figur 5 zeigt ein Beispiel, bei welchem ein mittleres Plattenelement 10 mit trapezförmigen Hohlkammern 9 beidseitig von ebenen Plattenelementen 11, 12 verschlossen ist, so dass sich die erforderlichen Hohlkammern 9 bilden.The air flow L required for forming an aerodynamic wall 7 is guided through hollow chambers 9 of the windbreak wall 6. In this embodiment, the hollow chambers 9 are trapezoidally configured ( FIG. 5 ). Wind protection walls 6 can be erected in particular from self-supporting plate elements, for example, have a trapezoidal or waveform. FIG. 5 shows an example in which a central plate element 10 with trapezoidal hollow chambers 9 is closed on both sides by flat plate elements 11, 12, so that form the required hollow chambers 9.

Die Figuren 3 und 4 zeigen, wie der Luftstrom L in die Hohlkammern 9 eingeleitet wird. Figur 3 zeigt, dass im unteren Randbereich der Windschutzwand 6 eine Stellklappe 13 angeordnet ist, die einen Teilluftstrom L1 von dem Kühlluftstrom K abzweigt. Die Stellklappen 13 können nach Bedarf geöffnet und geschlossen werden. Zusätzlich zu den Stellklappen 13 oder auch optional kann der Luftstrom L zumindest anteilig von Zusatzlüftern 14 erzeugt werden. Das Ausführungsbeispiel der Figur 4 zeigt, dass sich der Luftstrom L aus den Teilströmen L1 und L2 zusammensetzt, die durch den Zusatzlüfter 14 bzw. den Lüfter 3 aufgebracht werden.The FIGS. 3 and 4 show how the air flow L is introduced into the hollow chambers 9. FIG. 3 shows that in the lower edge region of the windbreak wall 6, an adjusting flap 13 is arranged, which branches off a partial air flow L1 from the cooling air flow K. The butterfly valves 13 can be opened and closed as needed. In addition to the butterfly valves 13 or optionally, the air flow L can be generated at least proportionally by additional fans 14. The embodiment of FIG. 4 shows that the air flow L from the partial flows L1 and L2 is composed, which are applied by the additional fan 14 and the fan 3.
