Description
Bei Anwendung von Filtern mit in Strömungsrichtung der Luft. engmaschiger werdenden Gewebelagen hat sich herausgestellt, daß es nicht zweckmäßig ist, die gesamte Staubmenge durch die untereinanderliegenden Gewebeschichten abzufangen und aufzunehmen, weil dabei in verhältnismäßig kurzer Zeit eine starke Verschmutzung eintritt und die Filter oft gereinigt werden-müssen. When using filters with in the direction of air flow. closer layers of fabric has turned out that it is not expedient to use the to intercept the entire amount of dust through the layers of tissue lying one below the other and take up, because a heavy pollution in a relatively short time occurs and the filters have to be cleaned often.
Es sollen deshalb mindestens zwei in gewissem Abstand voneinander angeordnete Filterplatten Verwendung finden, und zwar die zuerst beaufschlagte, mit in bekann,tef Weise in der Strömungsrichtung abnehmender Maschenweite. Diese Grobfilterplatte fängt die größeren Staubteilchen ab, sie ist herausnehmbar ausgebildet und kann in einfachster Weise durch Aufstoßen mit einer Kante auf eine feste Unterlage oder mit Hilfe eines Staubsaugers gereinigt werden. Diese Filterplatte fängt erfahrungsgemäß bereibs 80 bis goO/o des Staubes je nach dessen Beschaffenheit und Korngröße ab. There should therefore be at least two at a certain distance from each other arranged filter plates are used, namely the first acted upon, with, in a known, tef manner, mesh size decreasing in the direction of flow. These Coarse filter plate catches the larger dust particles, it is designed to be removable and can be done in the simplest way by pushing an edge on a solid surface or cleaned with the help of a vacuum cleaner. Experience has shown that this filter plate catches Above 80 to 100 / o of the dust, depending on its nature and grain size.
Anschließend wird die Luft erfindungsgemäß durch eine zweite in Abstand von der ersten angeordnete Filterplatte hindurchgeführt, die in an sich bekannter Weise aus Geweben mit weiter abnehmender Maschenweite besteht. Die Gewebefäden sollen in an. sich bekannter Weise ölbenetzt sein. Then, according to the invention, the air is spaced by a second passed by the first arranged filter plate, which is known per se Way consists of fabrics with a further decreasing mesh size. The fabric threads are supposed to in on. be oil-wetted in a known manner.
Von dieser Platte werden die restlichen Feinstaubteilchen abgefangen und aufgespeichert. Die Filterplatten werden von Zeit zu Zeit in üblicher Weise durch Tauchen in Filteröl gereinigt und neu benetzt.The remaining fine dust particles are caught on this plate and stored. The filter plates are from time to time in the usual way cleaned by immersion in filter oil and re-wetted.
Insbesondere in Geräten usw., die auf ganz niedrigen Filterwiderstand angewiesen sind, ist es jedoch wichtig, daß durch die Verwendung der doppelten Filterplatten der Widerstand der Filterkombination nicht zu groß wird. Da der Filterwiderstand sich mit der Luftgeschwindigkeit erhöht, besonders bei der nachgeschalteten benetzten Filterplatte, soll deren Fläche gegenüber der vorgeschalteten trockenen Grobfilterpiatte vergrößert werden, z. B. durch winklige Anordnung zur Fläche des ersten Filters oder durch gewölbte Ausbildung. Especially in devices etc. that have a very low filter resistance however, it is important that by using the double filter plates the resistance of the filter combination does not become too great. Because the filter resistance increases with the air speed, especially with the downstream wetted The area of the filter plate should be opposite the upstream dry coarse filter plate be enlarged, e.g. B. by angled arrangement to the surface of the first filter or by arched training.
Die Ausscheidung des Feinstaubes wird trotzdem in der olbenetzten feinporigen Platte nicht verringert, weil das feinporige Maschengewebe mit Ölbenetzung auch bei niedriger Luftgeschwindigkeit einen hohen Reinheitsgrad der gefilterten Luft bewirkt.The excretion of fine dust is still in the oil-wetted Fine-pored plate is not reduced because the fine-pored mesh fabric with oil wetting a high degree of purity of the filtered air even at low air speeds Air causes.
In der Zeichnung sind einige Ausführungsbeispiele dargestellt. Some exemplary embodiments are shown in the drawing.
Fig. I zeigt eine Bauart mit ebener Grobfilter-und dachförmiger Feinfilterpiatte, Fig. 2 eine weitere Bauform mit dachförmiger Grobfilter- und sägeförmiger Feiufilterplatte. -Das zunehmende Verhältnis der Feinfilterfläche zu der des Grobfilters ist- aus den Figuren ohne weiteres erkennbar. In allen Figuren slind mit I die trockene Grobfilterplatte, mit 2 die ölbenetzte Feinfilterplatte und mit 3 das Gehäuse bezeichnet. Fig. I shows a design with a flat coarse filter plate and a roof-shaped fine filter plate, 2 shows a further design with a roof-shaped coarse filter plate and a saw-shaped fine filter plate. -The increasing ratio of the fine filter area to that of the coarse filter is off easily recognizable from the figures. In all figures, the dry coarse filter plate is indicated by I, with 2 the oil-wetted fine filter plate and with 3 the housing.
PATENTANSPROCHE: I. Gewebefilter für Luft- oder Gasreinigung mit zwei oder mehr hintereinander angeordneten Filterplatte.n, die in Strötnungsrichtung -engmaschiger werdende Gewebelagen aufweisen, von denen die zuerst beaufschlagte Platte aus trockenen Gewebelagen und die zweite aus Gewebelagen besteht, die ölbenetzt sind, dadurch gekennzeichnet, daß die znveite (dritte usw.) Filterplatte (2') bei gleichbleibender Größe des Kanalquerschnitts eine größere Oberfläche aufweist als die vorhergehende Filterplatte. PATENT CLAIM: I. Fabric filter for air or gas cleaning with two or more filter plates arranged one behind the other, in the direction of flow - have more closely meshed layers of fabric, of which the first acted upon Plate consists of dry fabric layers and the second consists of fabric layers that are oil-wetted are, characterized in that the second (third etc.) filter plate (2 ') at constant size of the channel cross-section has a larger surface than the previous filter plate.
