Abstract
Description
Die Erfindung betrifft das Gebiet der Membranmodule zum Trennen von Stoffen unterschiedlichen Aggregatzustandes. Ein solches Membranmodul umfasst ein langgestrecktes Filterelement, das von wenigstens einem Längskanal durchzogen ist und aus einem porösen Werkstoff besteht, beispielsweise aus Keramik. Das Modul umfasst ferner ein Gehäuse, das das Filterelement umgibt und mit diesem einen Sammelraum bildet.The invention relates to the field of membrane modules for separating substances of different physical state. Such a membrane module comprises an elongated filter element, which is traversed by at least one longitudinal channel and consists of a porous material, for example of ceramic. The module further comprises a housing which surrounds the filter element and forms with this a collection space.
Ein solches Modul arbeitet wie folgt: In das eine Ende eines jeden Längskanals wird das zu behandelnde Medium eingeführt, das sogenannte Unfiltrat. Auf dem Wege des Unfiltrates tritt Filtrat durch die Wandfläche des Längskanals sowie durch das poröse Material des Filterelementes hindurch, gelangt in den genannten Sammelraum zwischen Filterelement und Gehäuse und wird von dort als Filtrat abgeführt. Das Unfiltrat tritt am anderen Ende der Längskanäle aus und wird gegebenenfalls rückgeführt zum erstgenannten Ende des Längskanales, um somit einen Kreislauf zu bilden. Die Wandflächen der Längskanäle sind mit einem Material beschichtet, das ebenfalls in bestimmtem Maße durchlässig ist.Such a module works as follows: In one end of each longitudinal channel, the medium to be treated is introduced, the so-called unfiltered material. Filtrate passes through the wall surface of the longitudinal channel and through the porous material of the filter element on the way of the unfiltrate, passes into said collecting space between the filter element and the housing and is discharged therefrom as filtrate. The unfiltered material exits at the other end of the longitudinal channels and is optionally returned to the first-mentioned end of the longitudinal channel, thus forming a cycle. The wall surfaces of the longitudinal channels are coated with a material which is also permeable to a certain extent.
Es gibt grundsätzlich zwei Bauarten solcher Module. Bei der einen Bauart ist eine Mehrzahl von Filterelementen vorgesehen, die nach Art eines Spaghetti einen einzigen Längskanal aufweisen. Mehrere solcher Filterelemente sind zu einem Bündel zusammengefasst (Spaghetti-Element).There are basically two types of such modules. In one type, a plurality of filter elements is provided which have a single longitudinal channel in the manner of a spaghetti. Several such filter elements are combined into a bundle (spaghetti element).
Bei der anderen Bauart weist ein einziges Filterelement eine Mehrzahl von Längskanälen auf (Multikanal-Element). Dabei ist es auch denkbar, mehrere solcher Multikanal-Elemente zusammenzufassen und daraus ein Membranmodul zu bilden.In the other type, a single filter element has a plurality of longitudinal channels (multi-channel element). It is also conceivable to combine several such multi-channel elements and to form a membrane module.
Die Erfindung betrifft beide Bauarten von Modulen.The invention relates to both types of modules.
Bei beiden Bauarten befindet sich jeweils am stirnseitigen Ende des Filterelementes beziehungsweise der Filterelemente eine stirnseitige Platte. Diese begrenzt den Ringraum zwischen dem Gehäuse und dem Filterelement beziehungsweise den Filterelementen, und zwar derart, dass der Ringraum gegen die äußere Umgebung dicht ist, wenigstens flüssigkeitsdicht. Das Abdichten kann problematisch sein, da Während des Betriebes unterschiedliche Temperaturen herrschen, die zu Expansion und Kontraktion von Bauteilen führen, und zwar in unterschiedlicher Weise. Die stirnseitigen Begrenzungsplatten können beispielsweise aus Edelstahl bestehen.In both types is located at the front end of the filter element or the filter elements an end plate. This limits the annular space between the housing and the filter element or the filter elements, in such a way that the annular space is sealed against the external environment, at least liquid-tight. Sealing can be problematic because during operation there are different temperatures that result in expansion and contraction of components in different ways. The frontal boundary plates may for example consist of stainless steel.
Ausführungsbeispiele sind bekannt geworden aus
Der Erfindung liegt die Aufgabe zugrunde, ein Modul einer der oben genannten Bauarten derart zu gestalten, dass die Verbindung zwischen dem Gehäuse und dem Filterelement absolut dicht ist und auch während des Betriebes dicht bleibt, und dass der Herstellungsaufwand gering ist.The invention has for its object to make a module of the above types such that the connection between the housing and the filter element is absolutely tight and remains tight during operation, and that the production cost is low.
Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst.This object is solved by the features of the independent claims.
Der grundlegende Gedanke der Erfindung besteht darin, dass auf den Endbereich der Filterelemente eine Schmelze aus Kunststoff aufgebracht wird, beispielsweise ein thermoplastischer Kunststoff, insbesondere ein Polymer. Handelt es sich um die oben genannte „Spaghetti”-Bauart, so werden sämtliche einzelnen Filterelemente auf einem Endbereich vom Kunststoff ummantelt. Der Kunststoff sperrt somit die Zwischenräume zwischen den Filterelementen ab. Er bildet einen Montagering, der – wiederum im Endbereich der Filterelemente – diese umgibt.The basic idea of the invention is that a melt of plastic is applied to the end region of the filter elements, for example a thermoplastic, in particular a polymer. If it concerns the above-mentioned "spaghetti" type, then all individual filter elements are encased on one end area by the plastic. The plastic thus blocks the spaces between the filter elements. It forms a mounting ring, which - again in the end region of the filter elements - surrounds them.
Der Ausdruck „Kunststoff” ist im weitesten Sinne zu verstehen. So kommen beispielsweise auch Duroplaste oder Zwei-Komponenten-Kunststoffe wie Epoxide oder Acrylate in Betracht.The term "plastic" is to be understood in the broadest sense. Thus, for example, thermosets or two-component plastics such as epoxies or acrylates into consideration.
Dieses Verfahren wird an den beiden Enden des Bündels von Filterelementen durchgeführt, sodass zwei Montageringe entstehen. Sodann wird das Gehäuse auf die beiden Montageringe und damit auf das Filterelement-Bündel aufgeschoben.This process is performed at the two ends of the bundle of filter elements, resulting in two mounting rings. Then, the housing is pushed onto the two mounting rings and thus on the filter element bundle.
Bei einem Multikanal-Element wird ein Montagering zunächst an einem Ende, und sodann am anderen Ende des Filterelementes aufgebracht, wiederum aus einer Kunststoffschmelze bestehend. Nach dem Aufbringen wird in beiden Fällen die Kunststoffschmelze aushärten gelassen. Gleiches wird am anderen Ende vorgenommen. Sodann wird wiederum das Gehäuse auf die beiden Montageringe aufgeschoben.In a multi-channel element, a mounting ring is first applied at one end, and then at the other end of the filter element, again consisting of a plastic melt. After application, the plastic melt is allowed to cure in both cases. The same is done at the other end. Then, in turn, the housing is pushed onto the two mounting rings.
Bei beiden Bauarten kann das Gehäuse aus demselben Material gebildet werden, wie die Montageringe. Das Gehäuse kann sogar mit einem der beiden Montageringe einteilig sein, und zwar durch Herstellen in einem einzigen Gussvorgang.In both types, the housing may be formed of the same material as the mounting rings. The housing may even be integral with one of the two mounting rings by manufacturing in a single molding operation.
Ein bekanntes Problem bei Filtereinrichtungen der genannten Bauart mit Keramik-Filterelementen besteht in der unterschiedlich starken Ausdehnung bei Wärmeeinwirkung. Das Problem tritt immer auf, wenn Materialien unterschiedlicher Wärmeausdehnungskoeffizienten verwendet werden.A known problem with filter devices of the type mentioned with ceramic filter elements consists in the different degrees of expansion when exposed to heat. The problem always occurs when materials of different thermal expansion coefficients are used.
Deshalb empfiehlt es sich, die Lagerung des Gehäuses wenigstens auf einem der Montageringe als Loslager auszubilden, sodass es nicht zu unzulässigen Wärmespannungen zwischen dem Keramikteil und dem Gehäuse kommt. Therefore, it is recommended to form the bearing of the housing at least on one of the mounting rings as a floating bearing, so that it does not come to unacceptable thermal stresses between the ceramic part and the housing.
Das Gehäuse kann mit Anschlüssen zum Zuführen oder Abführen von Medium versehen sein, zum Beispiel für das zu behandelnde Medium (sogenanntes Unfiltrat) oder für das behandelte Medium (Filtrat). Ist das Gehäuse aus thermoplastischem Material hergestellt, so bietet es sich an, die Anschlussstutzen anzugießen.The housing may be provided with ports for supplying or discharging medium, for example for the medium to be treated (so-called unfiltrate) or for the treated medium (filtrate). If the housing is made of thermoplastic material, it is advisable to apply the connecting pieces.
