Stand der TechnikState of the art
Zur Entfernung von Stickoxiden im Abgasstrom von Verbrennungsmotoren wird ein Reduktionsmittel in den Abgasstrom eingespritzt, um die Stickoxide mittels eines Katalysators in elementaren Stickstoff und Wasser umzuwandeln. Hierzu wird flüssiges Reduktionsmittel verwendet, in dem die aktive Substanz, beispielsweise Harnstoff, in Wasser gelöst ist. Das Reduktionsmittel wird in einem Tank gelagert, aus dem es mit einer Förderpumpe entnommen wird.to Removal of nitrogen oxides in the exhaust gas stream of internal combustion engines a reducing agent is injected into the exhaust stream to the nitrogen oxides by means of a catalyst in elemental nitrogen and water convert. This is liquid Reducing agent is used in which the active substance, for example Urea, dissolved in water is. The reducing agent is stored in a tank from which it is with a feed pump is removed.
Um das Einfrieren des flüssigen Reduktionsmittels zu verhindern, wird Anti-Frostschutzmittel zugesetzt, so dass übliche flüssige Reduktionsmittel zwischen –11C° und -40C° gefrieren. Da auch bei tiefen Temperaturen die Stickoxide reduziert werden müssen, muss das Reduktionsmittel zunächst aufgetaut werden. Dazu ist am Tankboden eine Heizung angebracht, die das gefrorene Reduktionsmittel auftaut. Das Mittel wird zunächst in dem heizungsnahen Bereich verflüssigt, wobei dieses aufgetaute Reduktionsmittel noch von einer dicken Eishülle umgeben ist. Das Absaugen des so eingeschlossenen flüssigen Reduktionsmittels würde zu einem Vakuum führen, so dass mit der Förderung des Reduktionsmittels erst begonnen wird, wenn die Heizung den Grossteil der gefrorenen Masse und die Eisdecke aufgetaut hat. Daher wird der Betriebsstart des Entstickungssystems deutlich verzögert.Around the freezing of the liquid Reducing agent to be added, antifreeze is added so that conventional liquid reducing agents between -11C ° and -40C ° freeze. Since even at low temperatures, the nitrogen oxides must be reduced, must the reducing agent first be thawed. For this purpose, a heater is mounted on the tank bottom, which thaws the frozen reducing agent. The agent is initially in liquefied in the area close to the heating, wherein this thawed reducing agent is still surrounded by a thick eggshell. The aspiration of the thus included liquid reducing agent would become a Lead vacuum, so with the promotion of the reducing agent is only started when the heating of the majority of frozen mass and the ice has thawed. Therefore, the Start of operation of Entstickungssystems significantly delayed.
Vorteile der ErfindungAdvantages of the invention
Mit der vorliegenden Erfindung ist es möglich, auch bei anfangs gefrorenem Tankinhalt das Entstickungssystem nach sehr kurzer Zeit zu starten. Erfindungsgemäß kam mit der Förderung des Reduktionsmittels begonnen werden, sobald sich eine ausreichende Menge an Reduktionsmittel gesammelt hat, wobei eine noch geschlossene Eisdecke und somit der hermetische Einschluss des flüssigen Reduktionsmittels den Betrieb des Systems nicht behindert. Erfindungsgemäß wird zusätzlich zur Tankheizung eine Belüftungsheizung vorgesehen, die so angeordnet ist, dass durch den Eispanzer hindurch ein Druckausgleich stattfinden kann. Mithilfe der Erfindung ist es möglich, einen entsprechenden Kanal vorzusehen, der zur Belüftung dient und somit die Volumenverminderung durch das geförderte flüssige Reduktionsmittel ausgleicht. Auf diese Weise ist es nicht erforderlich, mit dem Start des Entstickungssystems zu warten, bis die Tankheizung das Reduktionsmittel soweit aufgetaut hat, dass die Eisdecke eine Lücke aufweist, durch die ein Druckausgleich stattfinden kann.With of the present invention, it is possible, even at the beginning of frozen Tank contents start the denitrification system after a very short time. According came with the promotion of the reducing agent, as soon as a sufficient Amount of reducing agent has collected, with a still closed Ice cover and thus the hermetic inclusion of the liquid reducing agent the operation of the system is not hindered. According to the invention, in addition to Tank heating a ventilation heating provided, which is arranged so that through the ice sheet through Pressure equalization can take place. By means of the invention it is possible to have a appropriate channel, which serves for ventilation and thus the volume reduction through the sponsored liquid reducing agents balances. That way, it's not necessary to start the denitrification system to wait until the tank heating the reducing agent so far thawed that the ice cover has a gap through which a Pressure equalization can take place.
Kurze Beschreibung der ZeichnungenBrief description of the drawings
Anhand der Zeichnungen wird die Erfindung nachstehend erläutert.Based of the drawings, the invention will be explained below.
Es zeigen:It demonstrate:
Die
Ausführungsformembodiment
Gemäß einer
ersten Ausführung
der Erfindung wird eine Fluidleitung für einen Reduktionsmitteltank
vorgesehen, die mittels einer Belüftungsheizung beheizt werden
kann. Die Fluidleitung ist dafür vorgesehen,
das von der Tankheizung
In
einer bevorzugten Ausführung
ist die Heizung durchgehend über
einen Längsabschnitt
der Förderleitung
In einer bevorzugten Ausführungsform wird als Belüftungsheizung eine elektrische Heizeinrichtung verwendet. Vorzugsweise ist die elektrische Heizeinrichtung ein Draht, der um die Fluidleitung gewickelt ist, und so die Fluidleitung umfänglich umgreift. Statt Draht kann auch eine Heizfolie oder eine Heizschicht verwendet werden. Alternativ umfasst die Fluidleitung eine Belüftungsheizung, die sich zu der Fluidleitung längs erstreckt, parallel neben diese angeordnet ist und mit dieser wärmeleitend verbunden ist, beispielsweise durch mechanischen Kontakt. In diesem Fall kann die Belüftungsheizung aus einem Träger bestehen, beispielsweise ein stabförmiges Rohr, welches über einen Heizdraht, eine Heizfolie oder eine Heizschicht verfügt. Eine besonders einfache Herstellung ergibt sich, wenn die Belüftungsheizung über eine Länge der Fluidleitung vorgesehen ist, die dem gesamten im Tank befindlichen Abschnitt der Fluidleitung entspricht. Alternativ erstreckt sich die Belüftungsheizung entlang der gesamten Fluidleitung.In a preferred embodiment is used as ventilation heating used an electric heater. Preferably, the electric heater is a wire that wraps around the fluid line is, and so the fluid line circumferentially embraces. Instead of wire can also be a heating foil or a heating layer be used. Alternatively, the fluid line comprises a ventilation heater, extending longitudinally to the fluid line extends, is arranged parallel to this and with this heat-conducting is connected, for example by mechanical contact. In this Case can be the ventilation heater from a carrier exist, for example, a rod-shaped tube, which over a Heating wire, a heating foil or a heating layer features. A Particularly simple production results when the ventilation heater over a Length of Fluid line is provided, which is the entire in the tank Section of the fluid line corresponds. Alternatively, the extends Heating ventilation along the entire fluid line.
Erfindungsgemäß wird auch ein Reduktionsmitteltank vorgesehen, bei dem die mit der Belüftungsheizung ausgestattete Fluidleitung, wie oben beschrieben, eine Ansaugöffnung aufweist, die in der Nähe der Tankheizung angeordnet ist. Da in dem Bereich nahe der Tankheizung das Reduktionsmittel als Erstes schmilzt, erlaubt dies den Betrieb des Entstickungssystems bereits kurz nach Aktivierung der Tankheizung und der Belüftungsheizung.Also according to the invention a reducing agent tank provided in which the with the ventilation heating equipped fluid line, as described above, having a suction port, the nearby the tank heater is arranged. Because in the area near the tank heater the reducing agent melts first, this allows the operation the denitrification already shortly after activation of the tank heating and the ventilation heating.
Die Belüftungsheizung kann einteilig mit der Fluidleitung ausgeführt sein, beispielsweise indem diese in die Wand der Fluidleitung eingebettet ist. Alternativ ist die Belüftungsheizung rohrförmig und bildet eine innere Passage, in der die Fluidleitung angeordnet ist.The Heating ventilation can be made in one piece with the fluid line, for example by these embedded in the wall of the fluid line. Alternatively, the Heating ventilation tubular and forms an internal passage in which the fluid conduit is disposed is.
