Abstract

The soot filter is used to clean the exhaust gases of a Diesel engine. The exhaust gases are scrubbed by flowing through a container (3) filled with a washing liq. (4). The washing liq, which may be water or a low viscosity mineral oil, catches the soot particles so that they are deposited as a sediment which can from time to time be removed. USE/ADVANTAGE - Diesel engine exhaust system which can be used in vehicles of all kinds as well as in stationary plants.

Description

Gegenstand der nachstehend beschriebenen Erfindung ist eine Einrichtung, die den Zweck hat, Rußpartikel aus den Abgasen von Dieselmotoren vollständig zu entfernen. Das geschieht dadurch, daß die Auspuffgase in eine Waschflüssigkeit geleitet werden. Nachdem sie diese durchströmt haben, gelangen sie gereinigt ins Freie.The invention described below is a Device that has the purpose of soot particles from the exhaust gases completely remove from diesel engines. This happens characterized in that the exhaust gases are passed into a washing liquid will. After flowing through them, they arrive cleaned outdoors.

Die bisher angewandten Abgasrußfilter sind Festkörperfilter mit gitter- oder netzartiger Struktur von großer Oberfläche. In ihnen sollen die Rußpartikel der hindurchströmenden Aus­ puffgase zurückgehalten werden.The exhaust soot filters previously used are solid-state filters with a lattice or net-like structure with a large surface. In them, the soot particles are supposed to flow out puff gases are retained.

Die Wirkung dieser Filter ist unbefriedigend, da ein erheblicher Anteil an Rußpartikeln nicht zurückgehalten wird. Die Folge ist, daß größere Mengen Ruß weiterhin in die Luft gelangen.The effect of these filters is unsatisfactory because of a considerable one The proportion of soot particles is not retained. The result is, that larger amounts of soot continue to get into the air.

Das Filterverfahren, welches Gegenstand der Erfindung ist, wird in folgender Apparatur durchgeführt:The filtering method which is the subject of the invention is carried out in the following apparatus:

Die Abgase des Dieselmotors (1) werden zunächst in einen Gas­ kühler (2) geleitet, wo sie von ca. 600°C auf eine Temperatur, die zwischen 80°C und ca. 250°C liegt, abgekühlt werden. Die Abkühlung ist notwendig, weil ohne diese die Waschflüssigkeit durch das heiße Abgas zu stark aufgeheizt würde. Als Wasch­ flüssigkeiten kommen in Frage: Wasser, dünnflüssige Mineralöle oder Flüssigkeiten, deren Zusammensetzung die Kohlenstoff­ partikel chemisch bindet. Nachdem das Gas den Kühler passiert hat, gelangt es über eine Rohrleitung in den Filterbehälter (3). Dieser ist ein aufrecht stehendes zylindrisches Gefäß, das zum größten Teil mit Filterflüssigkeit (4) gefüllt ist. Das ruß­ haltige Gas wird an der Unterseite des Behälters in die Filter­ flüssigkeit geleitet und durchströmt diese von unten nach oben, wobei die Rußpartikel ausgewaschen werden. Sie sammeln sich im Bodenteil (5) des Filterbehälters als schlammige Ablagerung. Der Bodenteil ist abnehmbar, so daß er von Zeit zu Zeit gerei­ nigt werden kann. Ein trichterförmiger Verteiler (6), der auf seiner Oberseite mit einer großen Zahl von feinen Öffnungen versehen ist, sorgt dafür, daß das Abgas möglichst gleichmäßig über den größten Teil des Behälterquerschnitts verteilt wird. The exhaust gases from the diesel engine ( 1 ) are first passed into a gas cooler ( 2 ), where they are cooled from approx. 600 ° C to a temperature between 80 ° C and approx. 250 ° C. Cooling is necessary because without it the washing liquid would be heated up too much by the hot exhaust gas. Possible wash liquids are: water, low-viscosity mineral oils or liquids whose composition chemically binds the carbon particles. After the gas has passed the cooler, it reaches the filter container ( 3 ) via a pipe. This is an upright cylindrical vessel, which is largely filled with filter liquid ( 4 ). The soot-containing gas is passed at the bottom of the container into the filter liquid and flows through it from the bottom up, the soot particles being washed out. They collect in the bottom part ( 5 ) of the filter container as a muddy deposit. The bottom part is removable so that it can be cleaned from time to time. A funnel-shaped distributor ( 6 ), which is provided with a large number of fine openings on its top, ensures that the exhaust gas is distributed as evenly as possible over most of the cross-section of the container.

Das entrußte Gas entweicht über ein Rohr (7) in die Luft. Füll- (8) und Entleerungsventile (9) dienen zum Ablassen der verschmutzten Filterflüssigkeit und zum Wiederauffüllen des Filterbehälters. Liegt der Filterbehälter einbaubedingt höher als der Gaskühler, ist in die Rohrleitung, die beide mitein­ ander verbindet, ein Rückschlagventil einzubauen. Damit wird verhindert, daß Filterflüssigkeit in den Gaskühler und in die Auspuffleitung des Motors gelangt.The soot-released gas escapes into the air via a pipe ( 7 ). Filling ( 8 ) and emptying valves ( 9 ) serve to drain the dirty filter liquid and to refill the filter container. If the filter container is installed higher than the gas cooler, a non-return valve must be installed in the pipeline that connects the two. This prevents filter fluid from getting into the gas cooler and exhaust pipe of the engine.

Das beschriebene Abgasreinigungsverfahren kann überall wo Dieselmotoren eingesetzt werden, zur Anwendung kommen, also in Straßen-, Schienen-, Luft- und Wasserfahrzeugen sowie in stationär betriebenen Anlagen.The described exhaust gas purification process can be used anywhere Diesel engines are used in road, rail, air and water vehicles as well as in stationary systems.
