Description

Filter für strömende Gase Es ist bekannt, zur Entfernung von feinverteilten, festen oder flüssigen Beimengungen aus strömenden Gasen faserige Stoffe in Form von textilen Gebilden, wie Geweben, Gewirken oder auch in Form von einer Wirrlage von Stapelfasern auf Cellulosebasis zu verwenden. Filters for flowing gases It is known to remove finely divided, solid or liquid admixtures from flowing gases fibrous substances in the form of textile structures, such as woven, knitted or also in the form of a random layer of cellulose-based staple fibers.

Gegenstand der Neuerung ist ein Filter zur Entfernung von feinverteilten, festen oder flüssigen Beimischungen aus strömenden Gasen oder Dämpfen, der dadurch gekennzeichnet ist, dass der Filter ganz oder zum Teil aus wirren Fasern aus synthetischen, linearen Hochpolymeren besteht, wobei die Fasern vorwiegend einen Durchmesser zwischen 1 Mikron und 6 Mikron haben.The subject of the innovation is a filter for the removal of finely divided, solid or liquid admixtures from flowing gases or vapors that result is indicated that the filter is wholly or partly made of tangled fibers made of synthetic, linear high polymers, the fibers predominantly having a diameter between 1 micron and 6 micron.

Die bisher verwendeten Filter enthalten in der Hauptsache Fasern aus Naturfasern oder auch Fasern auf Kunststoffbasis, die jedoch ausnahmslos wesentlich dicker sind als die Filter des neuer-ungsgemässen Filters. In der nachstehenden Tabelle sind einige für die Filterherstellung gebräuchlichen Fasern mit dem dazugehörigen Durchmesser angegeben : Faserart : von bis -- Wolle * 17 ca. 100 Mikron Zellwolle.............. 20 ca. 50 Mikron Celluloseacetat....... 20 ca. 50 Mikron Polyamide, 18 30 Mikron Polyester.............. 15 30 Mikron \ Der Grad der Filterwirkung hängt in erster Linie von der Grösse der inneren Oberfläche dieser Gebilde ab, die ihrer- seits wieder bestimmt wird vom Durchmesser der in dem Filter enthaltenen Faser.The filters used so far mainly contain fibers made from natural fibers or also fibers based on plastic, which, however, are without exception much thicker than the filters of the newer-compliant filter. The following table shows some of the fibers commonly used in filter manufacture and their diameter: Fiber type: from to - Wool * 17 approx. 100 micron rayon .............. 20 approx. 50 micron cellulose acetate ....... 20 approx. 50 micron Polyamides, 18-30 microns Polyester .............. 15 30 microns \ The degree of filtering effect depends primarily on the Size of the inner surface of these structures, which their- on the other hand is determined by the diameter of the fiber contained in the filter.

Wie aus der Tabelle zu entnehmen ist, ist der Durchmesser der bisher-für Filterzwecke verwendeten Fasern zwischen 15 Mikron und 100 Mikron. Demgegenüber enthält der neuerungsgemässe Filter Fasern von 1-6 Mikron, vorzugsweise sogar von 2-3 Mikron Durchmesser.As can be seen from the table, the diameter is the previous one for Filtration purposes used fibers between 15 microns and 100 microns. In contrast The filter according to the invention contains fibers of 1-6 microns, preferably even of 2-3 microns in diameter.

Die Filterwirkung derartiger Filter beträgt ein'Vielfaches von derjenigen der bisher gebräuchlichen Filter. Die ideale Wirrlage der verwendeten Mikrofasern für die Herstellung der neuartigen Filter ist ein wesentliches zusätzliches Element für die Verbesserung der Filterwirkung.The filter effect of such filters is a multiple of that the filters commonly used up to now. The ideal random layer of the microfibers used for the production of the novel filter is an essential additional element for improving the filter effect.

Für die Anwendung dieser neuartigen Filter bestehen viele Möglichkeiten. Für die Reinigung von grossen Gasmengen, z. B. von Luft oder für die Filtration von Rauchgasen können Filter in Form grossflächiger Matten zur Anwendung kommen, wobei die Faserwirrlage zweckmässig zur mechanischen Stützung mit bisher gebräuchlichen Textilgeweben oder Geweben aus Metall oder Kunststoffdrähten verbunden werden (siehe Abbildung). In der gleichen Weise können derartige grosse Filter auch Anwendung finden zur Reinigung der Abluft von Kernreaktoren von radioaktiven staub-oder nebelförmigen Bestandteilen. l Für besondere Zwecke eignen sich Filter aus einer Mischung von verschiedenen Mikrofasern aus linearen Hochpolymere Die neuerungsgemässen Filter können ferner aus Mischungen von bisher verwendetem Fasermaterial z. B. Acetatfasern oder Papierfasern und ferner Fasern (Mikrofasern ? aus linearen Hochpolymeren bestehen.There are many possibilities for using this new type of filter. For cleaning large amounts of gas, e.g. B. from air or for the filtration of flue gases, filters in the form of large-area mats can be used, whereby the fiber tangle is conveniently connected to the previously used textile fabrics or fabrics made of metal or plastic wires for mechanical support (see figure). In the same way, such large filters can also be used for cleaning the exhaust air from nuclear reactors from radioactive dust or mist-like components. l Filters made from a mixture of different microfibers from linear high polymers are suitable for special purposes. B. acetate fibers or paper fibers and also fibers (microfibers? Consist of linear high polymers.

Schließlich hat es sich auch als vorteilhaft erwiesen, die zu reinigenden Gase,' : zuerst durch einen Filter aus Mikrofasern und anschliessend durch einen Filter aus normalen bisher verwendeten Fasern oder umgekehrt zu leiten.Finally, it has also proven advantageous to clean the Gases, ': first through a microfiber filter and then through a To conduct filters from normal previously used fibers or vice versa.
