Die vorliegende Erfindung bezieht sich auf solche Einrichtungen zur Beseitigung bzw. zum Geruchlosmachen der Auspuffgase Von Verbrcnnungskraftmaschincn, bei denen did Gase einer Filtration und Waschung iin'terj-; liegen. Einfache Ol>crlegungen zeigen indes, daß das nach dieser Richtung hin bisher bekannte gewöhnliche Filtrieren der Gase und ebenso ein Waschen durch Berührung mit Wasser usw.The present invention relates to such devices for removing or to make the exhaust gases odorless From Combustion power machines in which the gases of filtration and washing were interfered with; lie. Simple oil explanations, however, show that the usual filtering of the gases in this direction, known up to now, and the same washing by contact with water, etc.

eine hinreichende Reinigung der Gase nicht herbeizuführen vermag; Durch solche Filtra^ tion können nur die rein mechanischen Verunreinigungen, die in den Gasen sich befinden, zurückgehalten werden. Die Gase enthalten nun aber in erheblichem Grade noch unverbrannte, aber vergaste Bestandteile des Schmierr Öles, das nach allgemeinen Feststellungen in erster Linie den äußerst unangenehmen Gerucji der Auspuffgase herbeiführt. Gemäß vorlie'-unable to achieve adequate purification of the gases; Through such filtra ^ tion can only be the purely mechanical impurities that are in the gases, be held back. The gases contain but now to a considerable extent still unburned but gasified components of the lubricant Oil that is generally found in primarily causes the extremely unpleasant odor of the exhaust gases. According to the present

ao gender Erfindung soll daher die Filtration der ■'.-.■ Gase in ganz bestimmtem Sinne erfolgen, derart, daß neben der rein mechanischen Einwirkung auf die Gase hoch eine chemische Beeinflussung stattfindet, und zwar soll dies in der Ao gender invention should therefore be the filtration of the ■ '.-. ■ gases in a very specific sense, in such a way that, in addition to the purely mechanical effect on the gases, there is a high degree of chemical influence, namely in the

*$ Weise geschehen, daß die Auspuffgase im Filter zunächst einer Oxydation unterworfen werden, um nach Möglichkeit die unverbrannten, den Motor verlassenden Gasreste naclvträglich noch einer Verbrennung zu unter-ziehen, worauf dann die an sich bekannte mechanische Reinigung folgt und schließlich innerhalb des Filters eine Desodoration vor sich geht, dadurch, daß die in der beschriebe^ nen Weise vorgereinigten Gase mit an sich bekannten Mitteln, wie z. B. Knochenkohle, innig in Berührung gebracht werden. Die auf diese Weise filtrierten Gase werden dann gewaschen, aber nicht mit gewöhnlichem Wasser, sondern mit solchen Lösungen, welche geeignet sind, die etwa noch in den Gasen enthaltenen ölreste zu verseifen, so daß schließlich die Gase völlig gereinigt den Apparat verlassen müssen. * Happen $ manner that the exhaust gases initially an oxidation be in the filter subjected to drag under-naclvträglich possible, the unburned, leaving the engine gas remains still a combustion, whereupon it follows the per se known mechanical cleaning, and finally inside the filter a Desodoration goes on, in that the gases pre-cleaned in the manner described ^ NEN with means known per se, such as. B. charcoal, are brought into intimate contact. The gases filtered in this way are then washed, but not with ordinary water, but with solutions that are suitable for saponifying any oil residues still contained in the gases, so that finally the gases have to leave the apparatus completely cleaned.

Der Gcgcgenstand der Erfindung ist auf beiliegender Zeichnung zur Veranschaulichung gekommen, und zwar ist:The subject of the invention is on the accompanying drawing for illustration, namely:

Die Vorrichtung besteht aus einem geeignet gestalteten, zweckmäßig zylindrischen Gehäuse, welchem an dem einen Ende durch den Stutzen r' die vom Motor kommenden Auspuffgase zugeleitet werden. Innerhalb dieses Zylinders ist ein Filter.'2 angeordnet, das zweckmäßig die Gestalt einer fabrikatorisch herzustellenden Patrone· hat und frei nach Abnahme eines der Deckel in den Zylinder eingeschoben werden kann. Gemäß vorliegender Erfindung besteht nun dieses Filter aus drei Schichten, die bezüglich der Durchgangsrichtung der Gase hintereinander liegen. Die erste Schicht, die aus Mangänsuperoxyd bestehen kann, veranlaßt eine energische Oxydation, d.h. eine weitere Verbrennung der vom Motor direkt kommenden Verbrennungsprodukte mit der Folge, daß gerade die Ölreste, die infolge über- · mäßigen Schmierens zürn erheblichen Grade ah der Bildung des unangenehmen Geruches teilhaben, infolge dieser Oxydation beseitigt werden. Die hier notwendige chemische Reak-The device consists of a suitably designed, expediently cylindrical housing, which at one end the exhaust gases coming from the engine through the connection r ' be forwarded. A filter. '2 is arranged within this cylinder, which is expediently the The shape of a cartridge to be manufactured in a factory and free after one of the Cover can be pushed into the cylinder can. According to the present invention, this filter now consists of three layers that relate to the direction of passage of the gases lie one behind the other. The first layer that may consist of manganese peroxide, causes an energetic oxidation, i.e. a further combustion from the engine directly coming combustion products with the result that precisely the oil residues, which as a result of over- Moderate smearing leads to a considerable degree of formation of the unpleasant odor be eliminated as a result of this oxidation. The chemical reaction required here

tion is due to the high degree of heat of the gases much favored. Behind this oxidation filter follows an ordinary sand filter, that causes purely mechanical cleaning. The third filter, made of charcoal or similar substances is supposed to cause the deodorizing of the gases. One Such a filter cartridge composed of these three layers is expediently supported against a porous wall 3 and is supported by the

. other side by a _(same porous wall is limited. The resulting before the filter cavities 4 allows a uniform distribution is through the port i 'incoming gases. The caution due to this space 4 may be equipped with a safety valve 5. After the filter now the scrubbing liquid is provided for the gases which have lost a considerable amount of temperature after they have passed through the filter 2. This scrubbing liquid is expediently stored in porous materials or walls

Appropriately, there is a certain distance between the two containers, the * from one perforated rings 9 / is taken to prevent axial displacement.

From these inflows 8, the liquid supplied is then distributed laterally into the sponges enclosed by perforated walls. For easy insertion and replacement of these sponges, each container 6 or 7 is composed of two parts connected by a bayonet lock (FIG. 2), and each of these containers is also hand-held. ^: handle 10 provided, through which an easy insertion. lead and removal of this container from the cylinder 1 is made possible after one of the lids, for example the lid 11, is removed. Instead of sponges

Can of course asbestos wool or other fiber ■ material, also porous. Stone mass, come to the application. However, sponges or fiber material are recommended because they can be washed out very easily and then used again. The washing liquid, which is used here and is expediently stored in such porous walls, but can also act as an ordinary liquid bath, according to the present invention has such a nature that it exerts chemical reactions on the gases coming from the filter, namely hl the That it causes saponification of any of the substances still contained in the gases. For this purpose this liquid consists expediently of lime water, but it can also be made of any other alkaline or carbonate solution.
If it turns out that the series connection of the different filters and the washing bath causes the resistance to the exit of the exhaust gas to be too great, then within the same cylinder 1 (an impeller 12 can be arranged, which is driven by a shaft moved by the motor is driven in such a way that this impeller sucks in or presses out the exhaust gases and thus considerably reduces the resistance of the cleaning devices wheel 12. 1
