Description

Tropfenabscheiderprofil und Verfahren zu dessen Herstellung Droplet separator profile and process for its manufacture
Die vorliegende Erfindung betrifft ein als Lamellenprofil ausgebildetes Tropfenabscheiderprofil zur Ausbildung von eine Vielzahl von parallel zueinander und im Abstand voneinander angeordnete Lamellenprofile aufweisenden Tropfenabscheidereinheiten, das mindestens eine Ablösezone zur Abscheidung von Flüssigkeitstropfen aus einem am Lamellenprofil entlangströmenden Gas aufweist. The present invention relates to a droplet separator profile designed as a lamellar profile for the formation of a plurality of parallel and spaced-apart lamellar profiles having droplet separator units, which has at least one separation zone for separating liquid droplets from a gas flowing along the lamellar profile.
Derartige Tropfenabscheider sind bekannt. Sie weisen entsprechende Ablösezonen auf, die von einer Vielzahl von Strukturen gebildet sind. Hierzu gehören beispielsweise Nasen, Fangtaschen, Rinnen, Umlenkungen, Phasentrennkammern etc. Solche Strukturen werden beispielsweise durch Kanten, Knicken, Pressen oder Schweißen der entsprechenden Metallbleche hergestellt. Hierzu ist in der Regel eine Vielzahl von einzelnen Arbeitsschritten erforderlich, so dass die Herstellung von solchen Tropfenabscheiderprofilen zeit- und kostenaufwendig ist. Such droplet separators are known. They have corresponding separation zones which are formed by a large number of structures. These include, for example, noses, catch pockets, channels, deflections, phase separation chambers, etc. Such structures are produced, for example, by edging, folding, pressing or welding the corresponding metal sheets. This generally requires a large number of individual work steps, so that the production of such droplet separator profiles is time-consuming and costly.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Tropfenabscheiderprofil der eingangs beschriebenen Art zu schaffen, das sich besonders einfach und kostengünstig hersteilen lässt. The present invention is based on the object of providing a droplet separator profile of the type described above create that is particularly easy and inexpensive to manufacture.
Diese Aufgabe wird erfindungsgemäß bei einem Tropfenab- scheiderprofil der angegebenen Art dadurch gelöst, dass die Ablösezone mindestens eine durch Walzprofilierung hergestellte Einprägung aufweist. According to the invention, this object is achieved with a droplet separator profile of the specified type in that the detachment zone has at least one embossing produced by roll profiling.
Die erfindungsgemäße Lösung betrifft zwei Aspekte. Zum ei- nen wendet sie sich von den bekannten Herstellverfahren für derartige Strukturen von Ablösezonen ab und schlägt statt- dessen als Herstellverfahren eine Walzprofilierung vor. Zum anderen ersetzt die Erfindung die bekannten Strukturierungen, insbesondere Nasen und Fangtaschen, durch einfache Einprägungen, die durch Walzprofilieren hergestellt werden. Es hat sich gezeigt, dass derartige Einprägungen einfach und schnell hergestellt werden können, andererseits aber die für eine wirksame Phasentrennung gestellten Anforderungen erfüllen, so dass sich insgesamt ein derartiges als La- mellenprofil ausgebildetes Tropfenabscheiderprofil besonders einfach und rasch und somit kostengünstig hersteilen lässt. The solution according to the invention relates to two aspects. On the one hand, it turns away from the known manufacturing processes for such structures of detachment zones and instead proposes roll profiling as the manufacturing process. On the other hand, the invention replaces the known structuring, in particular noses and catch pockets, with simple impressions which are produced by roll profiling. It has been shown that such impressions can be produced easily and quickly, but on the other hand meet the requirements for effective phase separation, so that overall such a droplet separator profile designed as a lamellar profile can be produced particularly easily and quickly and thus inexpensively.
Beim Walzprofilieren (auch Rollformen oder Kaltwalzen von Profilen) wird beispielsweise ein ursprünglich ebenesIn roll profiling (also roll forming or cold rolling of profiles), for example, an originally flat
Blechband durch mehrere hintereinander angeordnete und angetriebene Walzenpaare geleitet, bis die gewünschte Profilform gebogen ist. Auf diese Weise können beliebige Profilformen hergestellt werden, wobei zu jedem Profilquerschnitt ein eigener Rollensatz erforderlich ist. Bei der durch Walzprofilierung hergestellten Einprägung handelt es sich vorzugsweise um eine Rundprägung. Derartig rund bis oval ausgebildete Einprägungen lassen sich besonders einfach aus flachen Blechstücken herstellen und haben darüber hinaus den Vorteil, dass sie weniger anfällig gegen Verschmutzungen sind als beispielsweise Umlenkungen, die scharfe Kanten aufweisen. Vorzugsweise ist eine derartige Walzprofilierung (Rundprägung) im Schnitt teilkreisförmig oder halb-oval ausgebildet. Sheet metal strip passed through several driven roller pairs arranged one behind the other until the desired profile shape is bent. In this way, any profile shapes can be produced, with a separate set of rollers being required for each profile cross-section. The embossing produced by roll profiling is preferably a circular embossing. Such round to oval shaped embossments can be produced particularly easily from flat pieces of sheet metal and also have the advantage that they are less susceptible to contamination than, for example, deflections that have sharp edges. Such a roll profiling (round embossing) is preferably designed in the form of a partially circular or semi-oval section.
Eine derartige Ablösezone kann erfindungsgemäß eine Einprägung oder mehrere Einprägungen aufweisen. Insbesondere finden mehrere hintereinander angeordnete Einprägungen Verwendung, die sich in gleiche oder in unterschiedliche Richtungen erstrecken können. So kann das Lamellenprofil beispielsweise abwechselnd Einprägungen in verschiedene Richtungen aufweisen. According to the invention, such a detachment zone can have one or more impressions. In particular, a number of embossings arranged one behind the other are used, which can extend in the same or in different directions. For example, the lamellar profile can have alternating impressions in different directions.
Auch wird eine Ausführungsform bevorzugt, bei der das Lamellenprofil Einprägungen nach Art einer Welle, insbesondere Sinuswelle, besitzt. Derartige wellenförmig ausgebildete Bereiche können beliebig lang ausgestaltet sein, um die gewünschte Phasentrennung bzw. Strömungsablösung zu erreichen. An embodiment is also preferred in which the lamella profile has impressions in the manner of a wave, in particular a sine wave. Such undulating areas can be of any length in order to achieve the desired phase separation or flow separation.
Auch kann das Lamellenprofil nach einer Einprägung eine Richtungsänderung aufweisen. So kann beispielsweise anstelle einer herkömmlich hergestellten scharfen Kante eine Einprägung, insbesondere eine Rundprägung, vorgesehen sein, wobei die Schenkel dieser Einprägung miteinander einen von 180° abweichenden Winkel bilden. Insgesamt wird eine Lösung bevorzugt, bei der das Tropfenabscheiderprofil überhaupt keine scharfen Biegekanten aufweist und diese durch entsprechende Rundprägungen ersetzt sind, so dass sämtliche Richtungsänderungen des Lamellenprofiles durch Rundprägungen gebildet sind. Diese Rundprägungen haben den Vorteil, dass die Verunreinigungsgefahr von derartigen Lamellenprofilen geringer ist als beim Stand der Technik und dass sich bessere Reinigungsmöglichkeiten ergeben. The lamellar profile can also have a change in direction after being impressed. For example, instead of a conventionally produced sharp edge, an embossing, in particular a round embossing, can be provided, the legs of this embossing with one another forming an angle other than 180 °. Overall, a solution is preferred in which the droplet separator profile has no sharp bending edges at all and these are replaced by corresponding circular embossings, so that all changes in direction of the lamellar profile are formed by circular embossings. These round embossings have the advantage that the risk of contamination of such lamellar profiles is lower than in the prior art and that there are better cleaning options.
Die vorliegende Erfindung betrifft des Weiteren ein Verfahren zur Herstellung eines mindestens eine Ablösezone aufweisenden, als Lamellenprofil ausgebildeten Tropfenabscheiderprofils der vorstehend beschriebenen Art. Das Verfahren ist dabei durch die folgenden Schritte gekennzeichnet: The present invention further relates to a method for producing a droplet separator profile, which has at least one detachment zone and is designed as a lamellar profile, of the type described above.

Unterziehen des Blechbandes mindestens einem Walzprofilierungsvorgang zur Ausbildung mindestens einer als Ablösezone dienenden Einprägung im Blechband. Subjecting the sheet metal strip to at least one roll profiling process to form at least one impression in the sheet metal strip serving as a detachment zone.
Erfindungsgemäß werden somit Strukturierungen des Tropfenabscheiderprofils, die als Ablösezone dienen, durch Walz profilieren (Biegen und Prägen) hergestellt, wobei hiermit mindestens eine Einprägung im Bereich der Ablösezone im Blechband geformt wird. Insbesondere werden dabei sämtliche Verformungsschritte des Blechbandes, die zur Herstellung eines als Tropfenabscheiderprofil dienenden Lamellenprofils erforderlich sind, überwiegend durch entsprechende Walzpro- filierungsschritte ausgeführt, wobei insbesondere mehrere Walzprofilierungsvorgänge nacheinander durchgeführt werden, um die mindestens eine Einprägung herzustellen und ggf. weitere Verformungen durchzuführen. According to the invention, structures of the droplet separator profile, which serve as a detachment zone, are produced by rolling profiling (bending and embossing), with at least one indentation being formed in the area of the detachment zone in the sheet metal strip. In particular, all deformation steps of the sheet metal strip that are required to produce a lamellar profile serving as a droplet separator profile are predominantly carried out by appropriate rolling processes. executed filing steps, wherein in particular several roll profiling processes are carried out one after the other in order to produce the at least one embossing and, if necessary, to carry out further deformations.
Die mindestens eine Einprägung wird bevorzugt als Rundprä gung oder Ovalprägung hergestellt, was die bereits vorste hend erläuterten Vorteile mit sich bringt. Weiter bevorzugt werden mehrere Einprägungen, insbesondere in verschiedenen Richtungen, durch Walzprofilieren hergestellt, die dann entsprechende Ablösezonen bilden. The at least one embossing is preferably produced as a round embossing or oval embossing, which brings the advantages already explained above. It is further preferred that several impressions, in particular in different directions, be produced by roll profiling, which then form corresponding release zones.
Bei einer speziellen Ausführungsform des erfindungsgemäßen Verfahrens wird die Einprägung durch Walzprofilieren (Bie- gen und Prägen) im ebenen Blechband hergestellt, wonach das mit der Einprägung versehene Blechband zur Herstellung des Lamellenprofils ggf. mehrfach gebogen wird. Auch die ent sprechenden Biegevorgänge können durch Profilieren durchgeführt werden. Insbesondere sieht die Erfindung vor, dass die Herstellung eines derartigen Lamellenprofils auf einer einzigen Walzprofilierungsmaschine erfolgt, die von dem entsprechenden Blechband durchlaufen wird, um die entsprechenden Verformungsvorgänge durchzuführen, die vorzugsweise durch Einprägungen gebildet sind. In a special embodiment of the method according to the invention, the embossing is produced by roll profiling (bending and embossing) in the flat sheet metal strip, after which the sheet metal strip provided with the embossing is bent several times to produce the lamellar profile. The corresponding bending processes can also be carried out by profiling. In particular, the invention provides that such a lamellar profile is produced on a single roll forming machine through which the corresponding sheet metal strip passes in order to carry out the corresponding deformation processes, which are preferably formed by embossing.
Das Blechband kann nach Durchführung des mindestens einen Walzprofilierungsvorganges bzw. von mehreren Profilierungs vorgängen zur Herstellung von einzelnen Lamellenprofilen durchtrennt werden. Es versteht sich, dass sich mit dem erfindungsgemäßen Ver¬ fahren sämtliche Merkmale der eingangs beschriebenen Tropfenabscheiderprofile verwirklichen lassen. Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen in Verbindung mit der Zeichnung im Einzelnen erläutert. Es zeigen: The sheet metal strip can be severed after performing the at least one roll profiling process or several profiling processes for the production of individual lamellar profiles. It goes without saying that all the features of the droplet separator profiles described at the beginning can be implemented with the method according to the invention. The invention is explained in detail below using exemplary embodiments in conjunction with the drawing. Show it:
Figur 1 zwei Lamellenprofile einer Tropfenabschei dereinheit nach dem Stand der Technik im Schnitt; Figure 1 shows two lamellar profiles of a droplet separator unit according to the prior art in section;
Figur 2 zwei Lamellenprofile einer Tropfenabschei dereinheit nach der Erfindung im Schnitt; Figure 2 shows two lamellar profiles of a droplet separator unit according to the invention in section;
Figur 3 eine schematische Darstellung der Herstellung eines erfindungsgemäß ausgebildeten La mellenprofils; Figur 4 eine weitere Ausführungsform von zwei erfin dungsgemäß ausgebildeten Lamellenprofilen einer Tropfenabscheidereinheit im Schnitt; und Figur 5 drei Stufen der Herstellung eines erfin dungsgemäßen Lamellenprofiles. FIG. 3 shows a schematic representation of the production of a lamella profile designed according to the invention; FIG. 4 shows a further embodiment of two lamella profiles of a droplet separator unit designed according to the invention in section; and FIG. 5 three stages in the production of a lamella profile according to the invention.
Figur 1 zeigt zwei parallel zueinander angeordnete Lamellenprofile 1 einer Tropfenabscheidereinheit des Standes der Technik im Vertikalschnitt. Die Lamellenprofile bilden zwischen sich Strömungswege, die von einem Gas durchströmt werden, um im Gas mitgeführte Flüssigkeitstropfen abzu scheiden. Der Abscheidevorgang findet hierbei an entsprechende Ablösezonen bildenden CJmlenkstellen statt, die von Kanten 2 gebildet werden, welche durch Kantung von ebenen Blechprofilen hergestellt werden. FIG. 1 shows two lamellar profiles 1, arranged parallel to one another, of a droplet separator unit of the prior art in vertical section. The lamellar profiles form flow paths between them, through which a gas flows be in order to separate droplets of liquid carried along in the gas. The deposition process takes place here at deflection points which form corresponding detachment zones and which are formed by edges 2 which are produced by folding flat sheet metal profiles.
Figur 2 zeigt zwei erfindungsgemäß ausgebildete Lamellenprofile 10 im Vertikalschnitt. Hierbei werden die entsprechenden Umlenkstellen nicht von scharfen Kanten, sondern von Rundprägungen 11, 12, 13, 14 gebildet, die durchFIG. 2 shows two lamella profiles 10 designed according to the invention in vertical section. Here, the corresponding deflection points are not formed by sharp edges, but by circular embossings 11, 12, 13, 14, which through
Walzprofilierung hergestellt werden. Diese Rundprägungen erstrecken sich in verschiedene Richtungen, wobei die bei den Rundprägungen 12, 13 nebeneinander angeordnet sind und eine Richtungsänderung des Profils bewirken. Dies ist auch mit den Rundprägungen 11, 14 der Fall. Auch hier bilden die entsprechenden Schenkel miteinander einen von 180° abweichenden Winkel. Roll forming are produced. These round embossments extend in different directions, the circular embossments 12, 13 being arranged next to one another and causing a change in direction of the profile. This is also the case with the round embossments 11, 14. Here, too, the corresponding legs form an angle other than 180 ° with one another.
Man erkennt, dass bei dieser Ausführungsform sämtliche Richtungsänderungen des Profils durch Rundprägungen erzeugt werden, wobei diese Rundprägungen in Bezug auf die ge wünschte Phasentrennung eine gute Wirkung zeigen und beispielsweise mit einer entsprechenden Walzprofilierungsmaschine (Rollformmaschine) besonders einfach und rasch her- stellbar sind. It can be seen that in this embodiment, all changes in direction of the profile are produced by circular embossing, these circular embossing having a good effect with regard to the desired phase separation and being particularly easy and quick to produce, for example with a corresponding roll forming machine (roll forming machine).
Figur 3 zeigt schematisch die Herstellung eines mit Rundprägungen 11 versehenen Lamellenprofils 10. Die in der Mit te dargestellte Rundprägung 11 wird durch eine mit einem entsprechenden Profil versehene Rolle 16 hergestellt, die beispielsweise mit dem Metallband einen Winkel von 90° bil- det. Die beiden seitlichen Rollen 15, 17 sind schräg zur Ebene des Metallbandes angeordnet und erzeugen entsprechen de Rundprägungen mit gleichzeitiger Abwinklung des Bandes. Figur 4 zeigt eine weitere Ausführungsform von Lamellenprofilen 20 im Schnitt. Die jeweiligen Profile besitzen zwei Rundprägungen 21, 22, wobei die Rundprägung 22 taschenför mig angeordnet ist, während die Rundprägung 21 im Schnitt etwa halbkreisförmig ausgebildet ist und eine Richtungsän- derung des Profils bewirkt. FIG. 3 shows schematically the production of a lamellar profile 10 provided with round embossings 11. The round embossing 11 shown in the middle is produced by a roller 16 provided with a corresponding profile which, for example, forms an angle of 90 ° with the metal strip. det. The two lateral rollers 15, 17 are arranged obliquely to the plane of the metal strip and produce corresponding de circular embossing with simultaneous bending of the strip. FIG. 4 shows a further embodiment of lamellar profiles 20 in section. The respective profiles have two circular embossings 21, 22, the circular embossing 22 being arranged in a pocket shape, while the circular embossing 21 is approximately semicircular in section and effects a change in the direction of the profile.
Figur 5 zeigt schematisch drei Stufen zur Herstellung eines Lamellenprofils. Die obere Darstellung a zeigt ein ebenes Metallband 30 im Querschnitt. Die mittlere Darstellung b zeigt, wie im ebenen Metallband eine Rundprägung 31 durch eine Rolle 33 einer entsprechenden Walzprofilierungsmaschine erzeugt wird. In einem weiteren Schritt (untere Darstellung c) werden dann zwei weitere Rundprägungen 32 mit abge winkelten Metallbandbereichen über zwei schräggestellte Rollen 34 erzeugt. Figure 5 shows schematically three stages for the production of a lamella profile. The upper illustration a shows a flat metal strip 30 in cross section. The middle illustration b shows how a round embossing 31 is produced in the flat metal strip by a roller 33 of a corresponding roll forming machine. In a further step (lower illustration c), two more circular embossings 32 with abge angled metal strip areas over two inclined rollers 34 are then generated.
Es versteht sich, dass die in Figur 5 schematisch dargestellte Vorgehensweise nur ein Ausführungsbeispiel für die Herstellung eines Lamellenprofils ist. Wesentlich ist, dass ein Lamellenprofil hergestellt wird, das mindestens eine Ablösezone zur Abscheidung von Flüssigkeitstropfen aus einem Gasstrom aufweist, welche mindestens eine durch Walzprofilierung hergestellte Einprägung aufweist. It goes without saying that the procedure shown schematically in FIG. 5 is only one exemplary embodiment for the production of a lamella profile. It is essential that a lamellar profile is produced which has at least one detachment zone for separating liquid droplets from a gas flow, which has at least one impression produced by roll profiling.
