Description

Beschreibung description
Nassabscheider Die Erfindung bezieht sich auf einen Nassabscheider nach Anspruch 1. Wet scrubber The invention relates to a wet scrubber according to claim 1.
Die mechanische Abtrennung von Wasser aus Nassdampf in einem Nassabscheider und damit die Reduzierung der Restfeuchte im Dampf ist eine Möglichkeit zur Effizienzsteigerung in Energie- und Prozessanlagen. The mechanical separation of water from wet steam in a wet scrubber and thus the reduction of residual moisture in the steam is one way to increase efficiency in energy and process plants.
Als Wellenabscheider ausgebildete Nassabscheider sind beispielsweise aus der JP 2010038548 A bekannt. Nassdampf, der in einen solchen Wellenabscheider eintritt, wird dort in durch mehrere Wellbleche ausgebildeten parallelen Kanälen geführt und aufgrund des Wellenprofiles mehreren schnellen Richtungsänderungen unterworfen. Trägheitskräfte drängen dabei Wassertröpfchen im Nassdampf gegen die Wellblechwände. Auf der Wellblechoberfläche verbinden sich diese Wassertröpf¬ chen zu immer größeren Tropfen. Die Schwerkraft, die Oberflä¬ chenspannung und der Impuls treiben dann diese Tropfen in entsprechend ausgebildete Taschen der Wellblechwände, wo sie gesammelt und weiter abgeleitet werden. Trained as a wave separator wet scrubbers are known for example from JP 2010038548 A. Wet steam, which enters such a wave separator, is guided there in parallel corrugations formed by a plurality of corrugated sheets and subjected to several rapid changes in direction due to the wave profile. Inertia forces urge water droplets in the wet steam against the corrugated iron walls. On the corrugated metal surface this Wassertröpf ¬ chen combine into larger and larger droplets. The gravity, the Oberflä ¬ voltage and the pulse then drive these drops in appropriately trained pockets of corrugated metal walls, where they are collected and further derived.
Die Abtrennung von Wasser bewirkt, dass der am anderen Ende des Wellenabscheiders ausströmende Dampf gegenüber dem in den Wellenabscheider eintretenden Nassdampf eine geringere Restfeuchte ausweist. Ein so in seinem Feuchtegehalt reduzierter Arbeitsdampf einer Energie- bzw. Prozessanlage führt zu einer Effizienzsteigerung der Anlage. Je geringer dabei der Druckverlust beim Durchströmen des Dampfes durch einen Nassabscheider ist, desto besser ist die Gesamtleistung der Anlage, die einen solchen Nassabscheider enthält. Solche Wellenab- scheider sind jedoch nicht einfach herzustellen und damit teuer . Aufgabe der Erfindung ist es, einen Nassabscheider zu schaffen, der einen möglichst geringen Druckverlust aufweist, ein¬ fach herzustellen ist und damit auch kostengünstig ist. Diese Aufgabe wird durch den Nassabscheider nach Anspruch 1 gelöst . The separation of water causes the steam flowing out at the other end of the wave separator to have a lower residual moisture compared with the wet steam entering the wave separator. A reduced in its moisture content of the working steam of an energy or process plant leads to an increase in efficiency of the plant. The lower the pressure loss when passing through the steam through a wet scrubber, the better the overall performance of the system containing such a wet scrubber. However, such Wellenab- separators are not easy to manufacture and therefore expensive. The object of the invention is to provide a wet scrubber, which has the lowest possible pressure loss, a ¬ is easy to produce and thus is inexpensive. This object is achieved by the wet scrubber according to claim 1.
Die Erfindung besteht nun darin, in einem Nassabscheider jeweils zwei einstückige Wellbleche mit unterschiedlichen Wel- lenformen und perforierten Flanken entsprechend so zu Wellblechwänden zu verbinden und diese Wellblechwände so anzuord¬ nen, dass zum einen für den einströmenden Nassdampf mehrere parallele Kanäle entstehen in denen der Nassdampf wiederkehrend einer Richtungsänderung unterworfen wird und dieser da- bei trotzdem möglichst reibungsarm diese Kanäle durchströmen kann, indem die perforierten Flanken der Wellbleche für den Nassdampf eine Art von "Trampolines" bilden, mit denen der Nassdampf in Richtung der nachfolgenden Wellblechflanke weiter beschleunigt wird, und zum anderen der Feuchtegehalt des Nassdampfes effektiv reduziert wird, indem schwerere Wasser¬ tröpfchen durch die perforierten Flanken von Nassdampf abgetrennt und in einzig durch die Verbindung zweier Wellbleche mit nahezu gleicher Wellenlänge aber verschiedenen Wellenbie¬ gungen entstehenden Taschen aufgefangen werden. Durch die er- findungsgemäße Ausbildung und Anordnung von über die gesamte oder nahezu gesamte Kanallänge einstückig ausgebildeten und parallel angeordneten Wellbleche und der sich aus jeweils zwei solcher regelmäßig miteinander verbundener Wellbleche hergestellten Wellblechwände zur Feuchtigkeitstrennung können so mit geringem Aufwand kostengünstige Nassabscheider mit ho¬ hem Wirkungsgrad einfach und schnell hergestellt werden. The invention now consists in a wet scrubber two-piece corrugated sheets having different WEL lenformen and to connect the perforated edges corresponding to corrugated metal walls so and these corrugated metal walls so anzuord ¬ NEN, on the one hand for the flowing wet steam plurality of parallel channels are formed in which the wet steam recurrently subjected to a change in direction and this while still possible low-friction flow through these channels by the perforated flanks of the corrugated sheets for the wet steam form a kind of "trampolines" with which the wet steam is further accelerated in the direction of the subsequent corrugated metal flank, and other of the moisture content of the wet steam, is effectively reduced by heavier water droplets ¬ separated by the perforated edges of wet steam and resulting in only by joining two corrugated sheets with nearly the same wavelength but different Wellenbie ¬ conditions Bags are caught. As a result of the construction according to the invention and arrangement of corrugated sheets formed in one piece over the entire or nearly entire channel length and the corrugated metal sheets produced from two such regularly interconnected corrugated sheets, cost-effective wet separators with high efficiency can be produced with little effort and be made quickly.
Besonders einfach lässt sich ein Nassabscheider herstellen, wenn die Wellenkämme Biegekanten sind und die Biegekanten der beiden Wellbleche unterschiedliche Biegewinkel aufweisen und die zwischen den Biegekanten liegenden Flanken nahezu ebene Flächen bilden. Dies kann auf einfachste Art und Weise durch regelmäßig wiederkehrendes Biegen eines planen Blechs erfol- n. Vorteilhafte Ausführungsformen sind den Unteransprüchen und 4 zu entnehmen. A wet scrubber can be produced particularly simply if the wave crests are bending edges and the bending edges of the two corrugated sheets have different bending angles and the flanks lying between the bent edges form almost flat surfaces. This can be done in the easiest way by regularly bending a flat sheet. n. Advantageous embodiments are given in the dependent claims and 4.
Die Erfindung soll nun anhand der nachfolgenden Figuren beispielhaft erläutert werden. Es zeigen: The invention will now be explained by way of example with reference to the following figures. Show it:
Fig. 1 zwei erfindungsgemäße Wellblechquerschnitte und de¬ ren Anordnung zu einer Wellblechwand, 1 shows two inventive corrugated metal cross sections and de ¬ ren arrangement to a corrugated metal wall,
Fig. 2 ein Querschnitt durch einen durch zwei Wellblechwände ausgebildeten Kanal zum Führen von Nassdampf, 2 shows a cross section through a channel formed by two corrugated metal walls for carrying wet steam,
Fig. 3 perspektivisch ein erfindungsgemäßer Nassabscheider . Fig. 3 in perspective an inventive wet scrubber.
Wie in FIG 1 dargestellt, besteht jede Wellblechwand des er¬ findungsgemäßen Nassabscheiders aus zwei gebogenen und perfo¬ rierten Wellblechen PI und P2, wobei die beiden Wellbleche hier Biegekanten mit unterschiedlichen Biegewinkeln al und a2 aufweisen. Zwischen den einzelnen Biegekanten eines Wellblechs befinden sich dabei die sogenannten Flanken. Diese bilden bei den hier dargestellten Wellblechen ebene, nicht gewölbte Flächen. Durch entsprechende Verbindungstechniken wie Punktschweißen oder Kleben werden jeweils zwei Wellbleche mit unterschiedlichen Biegewinkeln al und a2 zu einer Wellblechwand W miteinander verbunden. Die Taschen T zum Sammeln der abzuscheidenden Feuchtigkeit ergeben sich dabei beim Verbinden der beiden Wellbleche PI und P2 aus deren Geometrien mit den unterschiedlichen Biegewinkeln al und a2. Im Gegensatz zu den aus dem Stand der Technik bekannten Wellenabscheidern kann durch die erfindungsgemäße Anordnung von einstückigen Wellblechen auf eine aufwändige Konstruktion zur Ausbildung der Taschen verzichtet werden, so dass solche erfindungsgemäß hergestellten Nassabscheider einfach, schnell und kostengünstig herzustellen sind. Wie in FIG 2 angedeutet durchströmen die im Nassdampf D enthaltenen Wassertröpfchen zusammen mit diesem einen jeweils durch zwei Wellblechwände W ausgebildeten nahezu glatten Ka¬ nal K. Aufgrund ihrer Trägheit treffen sie dabei beim Durch- strömen des Kanals K wiederkehrend auf die perforierten Flan¬ ken der Wellblechwände W und bilden dort eine dünne Wasser¬ schicht, die dann durch eine Perforation Q im Wellblech W in der zwischen zwei Wellblechen W ausgebildeten Tasche T eintritt, und somit der DampfStrömung entzogen werden. As shown in Figure 1, each corrugated sheet metal wall of he ¬ inventive wet scrubber of two bent and perfo ¬ tured corrugated sheets PI and P2, wherein the two corrugated sheets here have bent edges with different bending angles al and a2. Between the individual bending edges of a corrugated sheet are the so-called flanks. These form flat, non-curved surfaces in the corrugated sheets shown here. By appropriate joining techniques such as spot welding or gluing two corrugated sheets with different bending angles al and a2 are connected to a corrugated metal wall W with each other. The pockets T for collecting the moisture to be deposited thereby arise when connecting the two corrugated sheets PI and P2 from their geometries with the different bending angles al and a2. In contrast to known from the prior art Wellenabscheidern can be dispensed with a complex design for the formation of the pockets by the inventive arrangement of one-piece corrugated sheets, so that such inventively produced Naßabscheider are simple, fast and inexpensive to produce. As indicated in FIG 2, the water droplets contained in the wet steam D flow through together with this one formed by two corrugated metal walls W almost smooth Ka ¬ nal K. Due to their inertia they encounter when passing flow of the channel K recurring to the perforated Flan ¬ ken the Corrugated metal walls W and there form a thin layer of water ¬ , which then enters through a perforation Q in the corrugated metal W in the formed between two corrugated sheets W pocket T, and thus the steam flow are withdrawn.
FIG 3 zeigt perspektivisch eine erfindungsgemäße Anordnung aus mehreren Wellblechwänden W, die eine Vielzahl paralleler Kanäle K für einen Nassabscheider zur Abtrennung von Wasser aus einem in den Nassabscheider eintretenden und die Kanäle K durchströmenden Nassdampf D ausbilden. Die Wellbleche der3 shows in perspective an inventive arrangement of a plurality of corrugated metal walls W, which form a plurality of parallel channels K for a wet scrubber for the separation of water from an entering into the wet scrubber and the channels K flowing through wet steam D. The corrugated sheets of
Wellblechwände W weisen jeweils Biegekanten mit zwei unter¬ schiedlichen Biegewinkeln und zwischen den Biegekanten liegenden ebenen Flächen als Flanken auf. Die zum eintretenden Nassdampf hin gerichteten Flanken der Wellbleche weisen dabei Perforationsflächen Q auf, durch die Wasser aus dem in den Kanälen K strömenden Nassdampf D mechanisch herausgetrennt und in entsprechend zwischen den zwei Wellblechen einer Wellblechwand ausgebildeten Taschen T gesammelt werden kann. Corrugated metal walls each have W bending edges on two underlying ¬ different union bending angles and between the bending edges flat surfaces as flanks. The flanks of the corrugated sheets directed towards the entering wet steam in this case have perforation surfaces Q, through which water can be mechanically separated from the wet steam D flowing in the channels K and collected in correspondingly formed pockets T between the two corrugated sheets of a corrugated iron wall.
