Zur Entfernung des giftigen Kohlenoxyds und zum Geruchlosmachen der Auspuffgase von Verbrennungsmotoren (Vergaser und Dieselmotoren) sind Filter vorgeschlagen S worden, die mit körnigen adsorbierend oder katalytisch wirkenden Filtermassen gefüllt sind. Die Wirkungsweise derartiger Filter ist an sich gut. Die Verwendung beider Arten von Filtern wurde aber bisher dadurch unmöglich gemacht, daß sie durch die festen und flüssigen, in Nebel- und Staubform vorhandenen Bestandteile der Auspuffgase (Ruß und unverbranntes, fein zerstäubtes öl) nach ziemlich kurzer Zeit verschmutzt und verstopft wurden. Versuche, diese Verstopfungen durch geeignete Filter zu verhindern, scheiterten bisher daran, daß die ersonnenen Vorrichtungen, wie -. Prallflächen, Umlenkbleche, Filter aus Sand, Koks, Metalldrehspänen, Siebe o.dgl., entweder nicht genügend wirkten oder sich ebenfalls nach kurzer Zeit verstopften. Die Überwachung, Reinigung und Auswechslung dieser genannten Filter verursachten erhebliche Schwierigkeiten. Man hat weiterhin versucht, die unverbrannt austretenden ölnebel durch Kühlung niederzuschlagen, erhielt aber hierbei umfangreiche Apparaturen, die schwerlich an den in Frage kommenden Stellen benutzt werden können.To remove the poisonous carbon monoxide and to make the exhaust gases odorless of internal combustion engines (carburetors and diesel engines) have been proposed with granular adsorbent or S filters catalytically active filter media are filled. How such filters work is good in itself. The use of both types of filters, however, has hitherto been impossible made that they exist through the solid and liquid, in the form of mist and dust Components of the exhaust gases (soot and unburned, finely atomized oil) became dirty and clogged in a fairly short time. Try to get rid of these clogs To prevent it through suitable filters, so far failed because the devised Devices, such as -. Baffles, baffles, filters made of sand, coke, metal turnings, Sieves or the like. Either did not work sufficiently or also after a short time clogged. The monitoring, cleaning and replacement of these filters mentioned caused considerable difficulties. Attempts continued to escape unburned Precipitation of oil mist by cooling, however, was extensive here Apparatus that can hardly be used in the places in question.

Es wurde nun gefunden, daß man zum Ziel kommt, wenn man Vorfilter aus porösem Material, wie z. B. Tuch, Asbestgewebe, porösem Filterstein, verwendet und die Filterfläche nach Art einer Filterpresse in einzelne Kammern zerlegt. Die große Oberfläche setzt die Strömungsdichte so herab, daß der mit öl getränkte Ruß nicht in die Poren der Filterstoffe hineingerissen wird, sondern sich in ganz lockerer Form auf der Oberfläche abscheidet, so daß er den Gasen nur einen äußerst geringen Widerstand bietet. Er kann nach einer gewissen Arbeitszeit des Filters oder andauernd leicht abgeschabt werden. Die zu reinigenden Auspuffgase strömen durch die Filterwände von außen nach innen in diese Kammern. Der Ruß scheidet sich demgemäß auf den Außenflächen der Kammern ab, und die gereinigten Gase strömen aus dem Innern der Kammern in ein Sammelrohr, welches sie dem Filter zuführt, in welchem « die unerwünschten Gasbestandteile des Auspuffs abfiltriert werden. Man kann das Filter mit Schabern versehen, die, vom Motor aus angetrieben, den Ruß kontinuierlich entfernen. Die Bedienung des Filters beschränkt , sich in diesem Fall darauf, daß man ein unter den Filterkammer wänden vorgesehenes Sammelgefäß für Ruß von Zeit zu Zeit durch Öffnen einer Klappe entleert.It has now been found that the goal is achieved if one prefilters made of porous material, such as B. cloth, asbestos fabric, porous filter stone, used and the filter surface dismantled into individual chambers like a filter press. The large surface area reduces the flow density so that the Soot soaked with oil is not pulled into the pores of the filter material, but rather itself is deposited in a very loose form on the surface, so that it is only one of the gases offers extremely low resistance. He can after a certain working time of the filter or be gently scraped off continuously. The exhaust gases to be cleaned flow through the filter walls from the outside inwards into these chambers. The soot separates accordingly on the outer surfaces of the chambers, and the purified gases flow out of the Inside the chambers in a collecting pipe, which leads them to the filter, in which « the unwanted gas components of the exhaust are filtered off. You can use the filter equipped with scrapers which, driven by the engine, continuously remove the soot. The operation of the filter is limited in this case to the fact that one under the filter chamber walls provided collecting vessel for soot from time to time Open a flap deflated.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. An dem Filtergehäuse a ist das Rohr b vorgesehen, welches die Auspuffgase in das Filtergehäuse einleitet. In dem Filtergehäuse α sind die Filterkammern c The drawing shows an embodiment of the invention. On the filter housing a , the pipe b is provided, which introduces the exhaust gases into the filter housing. The filter chambers c are in the filter housing α

angeordnet. Die Strömung der Auspuffgase erfolgt in der durch Pfeile angedeuteten Richtung. Wie aus der Zeichnung ersichtlich, treten die Auspuffgase von außen durch die porösen Wände der Filterkammern c und sammeln sich in dem an die Kammern angeschlossenen zentralen Rohr d, von wo aus sie dem Gasfilter zugeführt werden. In dem Filtergehäuse, und zwar um die Filterkammern herum, ist ein käfigartiges Gerüst e angebracht, das sich mittels der Welle g und dem Triebrad h beispielsweise von dem Motor in drehende Bewegung setzen läßt. Innerhalb des Gestelles e sind spiraligeDrahtfedern f gespannt, von denen in der Zeichnung der Übersichtlichkeit halber nur drei dargestellt sind, welche bei der Drehung des. Gestelles e an den porösen Filterwänden, auf deren Oberfläche der Ruß sitzt, schleifen und somit den Ruß andauernd entfernen. Letzterer fällt herunter und sammelt sich in dem am Boden des Filtergefäßes 0 angebrachten Rußsammler i, von wo aus er durch öffnen eines Schiebers oder einer Klappe k entfernt werden kann.arranged. The exhaust gases flow in the direction indicated by the arrows. As can be seen from the drawing, the exhaust gases pass from the outside through the porous walls of the filter chambers c and collect in the central pipe d connected to the chambers, from where they are fed to the gas filter. In the filter housing, namely around the filter chambers, a cage-like frame e is attached, which can be set in rotary motion by means of the shaft g and the drive wheel h, for example by the motor. Spiral wire springs f are tensioned within the frame e , of which only three are shown in the drawing for the sake of clarity, which grind against the porous filter walls on the surface of which the soot sits when the frame e is rotated and thus continuously remove the soot. The latter falls down and collects in the soot collector i attached to the bottom of the filter vessel 0, from where it can be removed by opening a slide or a flap k .
