Description
Die Erfindung betrifft ein Abscheidesystem nach dem Oberbegriff des unabhängigen Anspruchs 1 und ein Ansaugsystem für eine Brennkraftmaschine eines Kraftfahrzeugs.The invention relates to a separation system according to the preamble of independent claim 1 and an intake system for an internal combustion engine of a motor vehicle.
Aus der
Aus der
Das im Stand der Technik beschriebene Ansaugsystem arbeitet in einem bestimmten Durchflussbereich.The intake system described in the prior art operates in a certain flow range.
Der Erfindung liegt die Aufgabe zu Grunde, ein Abscheidesystem zu schaffen, welches eine hohe Abscheideleistung aufweist und auch bei höheren Durchflüssen wirksam ist. Diese Aufgabe wird durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 gelöst.The invention is based on the object to provide a separation system, which has a high separation efficiency and is effective even at higher flow rates. This object is solved by the characterizing features of independent claim 1.
Der wesentliche Vorteil der Erfindung liegt darin, dass mehrere Abscheider parallel zueinander angeordnet sind, wobei die Drallerzeuger der benachbart liegenden Abscheider einen gegensinnigen Drall erzeugen. Dies hat zur Folge, dass die abgeschiedene Flüssigkeit im Austrittsbereich mäanderförmig entlang eines Austragsystems fließt und sich ein gemeinsamer Flüssigkeitsstrom ausbilden kann, welcher zu einem Abfluss geleitet wird. Gemäß einer Ausgestaltung der Erfindung ist vorgesehen, die unmittelbar benachbart liegenden Abscheider so zu gestalten, dass ein gegensinninger Drall entsteht.The essential advantage of the invention is that a plurality of separators are arranged parallel to one another, with the swirl generators of the adjacent separators generating an opposing swirl. This has the consequence that the separated liquid flows in the exit area meandering along a discharge system and a common liquid flow can form, which is passed to a drain. According to one embodiment of the invention, it is provided to make the immediately adjacent separator so that a gegensinninger spin arises.
Eine weitere Ausgestaltung der Erfindung sieht vor, die Abscheider in vertikaler Richtung benachbart anzuordnen. Dies bedeutet, dass die abgeschiedene Flüssigkeit auf Grund der Schwerkraft nach unten fließt und gemeinsam zu einem Sammelbehälter gelangt.A further embodiment of the invention provides to arrange the separator adjacent in the vertical direction. This means that the separated liquid flows downwards due to gravity and arrives together at a collecting container.
Zur Vermeidung eines Druckverlustes ist in einer anderen Ausgestaltung der Erfindung das Außenrohr des Abscheiders mit einem erweiterten Abscheidebereich ausgestaltet. Dies bedeutet, dass der offene Durchmesser zum Durchtritt des Luftstroms nicht verjüngt werden muss. Weiterhin bedeutet dies auch, dass das an der Wand abgeschiedene Wasser bzw. die Flüssigkeit nicht mehr in die Ansaugluft hinein gerissen werden kann. Hierbei können z. B. Erweiterungswinkel von 0° bis 60° realisiert werden, wobei Erweiterungswinkel im Bereich von 20° bis 30° besonders vorteilhafte Abscheidungsgrade erzeugen.To avoid a pressure loss, in another embodiment of the invention, the outer tube of the separator is configured with an extended separation region. This means that the open diameter does not have to be tapered for the passage of airflow. Furthermore, this also means that the water deposited on the wall or the liquid can no longer be torn into the intake air. This z. B. expansion angle of 0 ° to 60 ° can be realized, with extension angles in the range of 20 ° to 30 ° produce particularly advantageous Abscheidungsgrade.
Gemäß einer weiteren Ausgestaltung der Erfindung verfügt das Innenrohr über einen sich erweiternden Verzögerungsbereich, wodurch Druckverluste in der Ansaugluft ausgeglichen werden können. In dem Verzögerungsbereich wird der Querschnitt vergrößert, wodurch die Ansaugluftströmung verlangsamt und ein Druckanstieg erzeugt wird. Für den Austritt der Flüssigkeit ist ein trichterförmiger Auslass vorgesehen. Der Auslass kann mit einem Ventil verschlossen werden, um eventuelle Rückströmungen zu vermeiden. Das Abscheidesystem wird in vorteilhafter Weise angewendet für eine Brennkraftmaschine, wobei das Abscheidesystem in der Rohluftleitung angeordnet ist und dort die Ansaugluft entfeuchtet.According to a further embodiment of the invention, the inner tube has a widening delay region, whereby pressure losses in the intake air can be compensated. In the deceleration region, the cross-section is increased, thereby slowing down the intake air flow and generating an increase in pressure. For the discharge of the liquid, a funnel-shaped outlet is provided. The outlet can be closed with a valve to prevent any backflow. The separation system is advantageously used for an internal combustion engine, wherein the separation system is arranged in the raw air line and there dehumidifies the intake air.
Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und der Zeichnung hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird.These and other features of preferred embodiments of the invention will become apparent from the claims and from the description and the drawings, wherein the individual features are realized individually or in each case in the form of sub-combinations in the embodiment of the invention and in other fields and can represent advantageous and protectable versions for which protection is claimed here.
