Die Erfindung bezieht sich auf die Verwendung von Kapillarrohren mit eingearbeiteten Poren als Filtereinsätze für die Aufbereitung und Reinigung von Fluiden.The invention relates to the use of capillary tubes with incorporated pores as filter inserts for the treatment and purification of fluids.

Die derzeit am Markt befindlichen Kapillarrohr-Filter bestehen hauptsächlich aus Kunststoff mit Poren kleiner 1 Mikron und Wandstärken bis zu 1 mm.The capillary tube filters currently on the market consist mainly of plastic with pores smaller than 1 micron and wall thicknesses up to 1 mm.

Diese Kunststoffkapillaren sind nicht eigenstabil und können nur in Verbindung mit einem Gehäuse eingesetzt werden. In Abhängigkeit von der Fluidtemperatur ist die Druckbeständigkeit von innen nach aussen und von aussen nach innen sehr gering. Deshalb werden die Kunststoffmembranen hauptsächlich im Querstrom betrieben.These plastic capillaries are not inherently stable and can only be used in conjunction with a housing. Depending on the fluid temperature, the pressure resistance from the inside to the outside and from the outside to the inside is very low. The plastic membranes are therefore mainly operated in cross-flow.

Die unregelmäßige Porenstruktur erleichtert An- und Einlagerungen von Verunreinigungen und beeinträchtigt die Reinigung dieser Kunststoffkapillaren erheblich.The irregular pore structure facilitates the accumulation and storage of contaminants and significantly impairs the cleaning of these plastic capillaries.

Außerdem ist die weit gefächerte Porengrößenverteilung für viele Praxisanwendungen von Nachteil.In addition, the wide pore size distribution is a disadvantage for many practical applications.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, für verschiedene Randbedingungen einen Filtereinsatz zu schaffen, der neben der Eigenstabilität auch bei höheren Betriebstemperaturen vergleichsweise hohe Druckstabilität in beiden Richtungen aufweist.The present invention is based on the object of creating a filter insert for various boundary conditions which, in addition to its inherent stability, also has comparatively high pressure stability in both directions at higher operating temperatures.

Gleichzeitig soll die spezifische Filteroberfläche hoch sein und die Eignung für die Filtration von kleinen Fluidmengen sowohl im Querstrom als auch Dead-end gegeben sein.At the same time, the specific filter surface should be high and the filter should be suitable for the filtration of small fluid quantities both in cross-flow and dead-end.

Durch die Verwendung von metallischen dünnwandigen Kapillarrohren mit Durchmessern bis 10 mm, in die Poren oder Schlitze geschnitten sind, werden diese gestellten Anforderungen erfüllt.These requirements are met by using metallic thin-walled capillary tubes with diameters of up to 10 mm, into which pores or slots are cut.

Die Porenstruktur ist regelmäßig aufgebaut und die Porenverteilung gegenüber den Kunststoffkapillaren relativ eng. Dadurch eignet sich dieses Kapillarrohr-Filter gut für die definierte Trennaufgabe und gleichzeitig ist die Regenerierfähigkeit des Kapillarrohr-Filters durch Rückspülung stark verbessert.The pore structure is regular and the pore distribution is relatively narrow compared to plastic capillaries. This makes this capillary tube filter well suited for the defined separation task and at the same time the regeneration ability of the capillary tube filter is greatly improved by backwashing.

Bei leicht anhaftentenden Verunreinigungen ist der Kapillarrohr-Filter mit einer Antihaftbeschichtung versehen, die auch die innere Porenoberfläche einschließt. Dadurch haften die abzuscheidenden Verunreinigungen weniger an der Filteroberfläche und in den Poren und sind gleichzeitig durch Rückspülung oder mechanische Reinigung leichter zu entfernen.For easily adhering contaminants, the capillary tube filter is provided with a non-stick coating that also covers the inner pore surface. This means that the contaminants to be separated adhere less to the filter surface and in the pores and are also easier to remove by backwashing or mechanical cleaning.

Insbesondere die Herstellung der Poren unler 100 Mikron bei hohen freiem Durchströmungsquerschnitl bis zu ca. 40% gestattet den Einsatz dieser Kapillarrohr-Filter in Anwendungen, bei denen unter höheren Temperaturen und Drücken auch kleinere Fluidmengen gefiltert werden.In particular, the production of pores below 100 microns with high free flow cross-sections of up to approx. 40% allows the use of these capillary tube filters in applications where smaller quantities of fluid are filtered under higher temperatures and pressures.

Der Kapillarrohr-Füler kann als einzelnes Kapillarrohr oder als Bündel parallel geschalteter Kapillarrohre eingesetzt werden.The capillary tube filler can be used as a single capillary tube or as a bundle of capillary tubes connected in parallel.
