Description
Die Erfindung betrifft eine Vorrichtung zur Reinigung eines Partikelfilters nach dem Oberbegriff von Anspruch 1 und ein Verfahren zur Reinigung eines Partikelfilters nach dem Oberbegriff von Anspruch 7.The invention relates to a device for cleaning a particulate filter according to the preamble of
Bekannt ist es, den Partikelfilter bei einer Verunreinigung zu tauschen und aufwendig in einer Spezialeinrichtung durch Verbrennen oder einer großen Menge Reinigungsflüssigkeit zu reinigen, was häufig ein nicht zufriedenstellendes Ergebnis liefert.It is known to replace the particulate filter in an impurity and consuming to clean in a special facility by burning or a large amount of cleaning liquid, which often provides an unsatisfactory result.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zum Reinigen eines Partikelfilters bereitzustellen, die einen sicheren, wartungsarmen Betrieb mit einem hohen Wirkungsgrad ermöglicht.The object of the present invention is to provide a device for cleaning a particulate filter, which enables safe, low-maintenance operation with high efficiency.
Die Aufgabe wird gelöst durch eine Vorrichtung zur Reinigung eines Partikelfilters von Verbrennungsmotoren, mit einem Mittel zur Bevorratung von flüssigem Reinigungsmittel unter Druck, mit einem Druckminderer bis auf einen Druck von etwa 2 bar, mit einem Mittel zum Transport des Reinigungsmittels bis zu einer Öffnung eines Innenraums des Partikelfilters, mit einem Mittel zum Erzeugen einer schaumartigen Konsistenz des Reinigungsmittels, insbesondere durch Übergang und/oder Ausdehnung in einen Bereich mit vergrößertem Volumen, nach Eintritt des Reinigungsmittels in die Öffnung des Innenraums des Partikelfilters.The object is achieved by a device for cleaning a particle filter of internal combustion engines, with a means for storing liquid detergent under pressure, with a pressure reducer to a pressure of about 2 bar, with a means for transporting the detergent to an opening of an interior of the particulate filter, with a means for producing a foam-like consistency of the cleaning agent, in particular by transition and / or expansion in an area with increased volume, after the entry of the cleaning agent in the opening of the interior of the particulate filter.
Durch die erfindungsgemäße Vorrichtung wird der Partikelfilter Reinigungsmittel, das im Mittel zur Bevorratung flüssig ist und sich dann im Innenraum des Partikelfilters zu einem Schaum ausdehnt, nahezu vollständig gefüllt und somit mit einer geringen Menge Reinigungsmittel vollständig benetzt und somit in allen Bereichen gesäubert.By means of the device according to the invention, the particulate filter cleaning agent, which is liquid in the reservoir for storage and then expands in the interior of the particulate filter into a foam, is almost completely filled and thus completely wetted with a small amount of cleaning agent and thus cleaned in all areas.
Die Erzeugung des Schaums kann auf einfache Weise einfach durch die physikalische Ausdehnung aus einem Überdruckbereich im Mittel zum Transport in einen größeren Bereich mit niedrigerem Druck im Innenraum des Partikelfilters geschehen. Das Mittel zum Transport reicht nur bis vor den Innenraum und wird somit nicht verschmutzt oder kann nicht eventuell im Innenraum abbrechen und somit den Partikelfilter in seiner Funktion gefährden. Der einzusetzende Druck ist relativ gering und durch den Druckminderer abgesichert, so dass keine Gefährdung beim Bedienen entstehen kann.The generation of the foam can be done simply by the physical expansion of an overpressure area in the means for transport in a larger area with lower pressure in the interior of the particulate filter in a simple manner. The means of transport extends only to the interior and is therefore not polluted or may not break off in the interior and thus jeopardize the function of the particulate filter. The pressure to be used is relatively low and secured by the pressure reducer, so that no danger can arise during operation.
Vorteilhaft ist es, wenn das Mittel zur Bevorratung einen Druckbecher mit einer Druckbecherpistole umfasst.It is advantageous if the means for storing comprises a pressure cup with a pressure cup gun.
Vorteilhaft ist es, wenn das Mittel zum Transport einen Anschlussschlauch mit einem Mindestdurchmesser aufweist, der größer als die Öffnung ist, die in den Innenraum des Partikelfilters führen, so dass der Anschlussschlauch nicht in den Innenraum des Partikelfilters zu führen ist.It is advantageous if the means for transport has a connection hose with a minimum diameter which is larger than the opening, which lead into the interior of the particulate filter, so that the connection hose is not to be led into the interior of the particulate filter.
Vorteilhaft ist es, wenn das Mittel zum Transport mit einer Schnellkupplung an dem Druckbecher zu befestigen ist.It is advantageous if the means for transport with a quick coupling is to be attached to the pressure cup.
Vorteilhaft ist es, wenn das Mittel zum Transport einen versiegelten Schlauch zur Leitung zu einem Eingang eines Differenzdrucksensors an dem Partikelfilter umfasst, insbesondere dem Vordereingang des Differenzdrucksensors, bezogen auf die Strömungsrichtung von Partikeln durch den Partikelfilter.It is advantageous if the means for transport comprises a sealed hose for conducting to an input of a differential pressure sensor on the particle filter, in particular the front input of the differential pressure sensor, based on the flow direction of particles through the particle filter.
Vorteilhaft ist es, wenn das Reinigungsmittel in schaumartige Konsistenz umgewandelt den Innenraum des Partikelfilters im Wesentlichen füllt.It is advantageous if the cleaning agent, converted into a foam-like consistency, essentially fills the interior of the particle filter.
Die Aufgabe wird ebenfalls gelöst durch ein Verfahren zur Reinigung eines Partikelfilters, insbesondere unter Verwendung einer Vorrichtung nach einem der Ansprüche 1 bis 6, wobei in eine Öffnung vor dem Einströmen des Partikelstromes in den Partikelfilter eine Reinigungsmittel unter einem Druck von kleiner/gleich 2 bar aus einem Mittel zur Bevorratung durch ein Mittel zum Transport bis vor die Öffnung geliefert wird und sich dann im Innenraum des Partikelfilters zu einer schaumartigen Konsistenz ausdehnt.The object is also achieved by a method for cleaning a particulate filter, in particular using a device according to one of
Vorteilhaft ist es, wenn das Reinigungsmittel in einen Vordereingang eines Differenzdrucksensors eingefüllt wird.It is advantageous if the cleaning agent is filled in a front input of a differential pressure sensor.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen und der nachstehenden Beschreibung, in der Ausführungsbeispiele des Gegenstands der Erfindung in Verbindung mit den Zeichnungen näher erläutert sind.Further features and advantages of the invention will become apparent from the claims and the following description in which embodiments of the subject invention in conjunction with the drawings are explained in more detail.
