Abstract
Description
Die Erfindung betrifft einen Flüssigkeitsverdampfer, insbesondere für eine Brennkraftmaschine eines Kraftfahrzeuges nach dem Gattungsbegriff des Patentanspruchs 1.The Invention relates to a liquid evaporator, especially for an internal combustion engine of a motor vehicle according to the preamble of claim 1
Ein
derartiger Flüssigkeitsverdampfer
ist aus der
Bei dem bekannten Flüssigkeitsverdampfer ist eine Flüssigkeitszufuhreinrichtung vorgesehen, die für eine zum Verdampfer koaxiale Zuführung mittels eines Kapillarrohres sorgt, das durch den Heizstab hindurchgeht und an der dem Körper abgewandten Seite des Heizstabes im Verdampferraum mündet.at the known liquid evaporator a liquid supply device provided for that a coaxial to the evaporator feeder by means of a capillary tube which passes through the heating rod and on the body opposite side of the heating element in the evaporator chamber opens.
Bei einem derartigen Flüssigkeitsverdampfer, der in Form eines Kapillarverdampfers ausgebildet ist, ist es als nachteilig anzusehen, dass der Durchsatz an zu verdampfender Flüssigkeit begrenzt ist und die Gefahr des Verkokens in dem Kapillarrohr besteht.at such a liquid evaporator, which is in the form of a capillary evaporator, it is as disadvantageous to see that the throughput of liquid to be evaporated is limited and there is a risk of coking in the capillary tube.
Die der Erfindung zugrunde liegende Aufgabe besteht daher darin, einen Flüssigkeitsverdampfer nach dem Gattungsbegriff des Patentanspruchs 1 zu schaffen, der eine geringere Verkokungsneigung zeigt und die Flüssigkeit mit einem höheren Durchsatz verdampfen kann.The The object underlying the invention is therefore a Liquid evaporator after to provide the generic concept of claim 1, a shows lower coking tendency and the liquid with a higher throughput can evaporate.
Der erfindungsgemäße Flüssigkeitsverdampfer soll darüber hinaus kompakt ausgebildet sein und sich für verschiedene Flüssigkeiten, wie beispielsweise Wasser, Dieselkraftstoff und Harnstoff eignen.Of the Liquid evaporator according to the invention should over it be made compact and suitable for various liquids, such as water, diesel fuel and urea are suitable.
Diese Aufgabe wird gemäß der Erfindung durch die Ausbildung gelöst, die im Patentanspruch 1 angegeben ist.These Task is carried out according to the invention solved the training, which is specified in claim 1.
Besonders bevorzugte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Flüssigkeitsverdampfers sind Gegenstand der Ansprüche 2 bis 11.Especially preferred embodiments and further developments of the liquid evaporator according to the invention are the subject of the claims 2 to 11.
Der erfindungsgemäße Flüssigkeitsverdampfer hat ersichtlich einen einfachen Aufbau, da insbesondere der Heizstab aus der üblichen Glühkerzen- oder Flammglühkerzenfertigung in Großserie herstellbar ist.Of the Liquid evaporator according to the invention Obviously has a simple structure, since in particular the heating element from the usual Glow plug or flame glow plug production Can be mass produced is.
Der erfindungsgemäße Flüssigkeitsverdampfer ist für verschiedene Flüssigkeiten einsetzbar und zeigt bei der Verdampfung von Dieselkraftstoff eine geringe Verkokungsneigung.Of the Liquid evaporator according to the invention is for different liquids can be used and shows in the evaporation of diesel fuel low coking tendency.
Ein weiterer Vorteil besteht darin, dass der erfindungsgemäße Flüssigkeitsverdampfer gute Regeleigenschaften zeigt und bei einer kurzzeitigen Veränderung des Durchsatzes an zu verdampfender Flüssigkeit keine Flüssigkeit austritt.One Another advantage is that the liquid evaporator according to the invention shows good control properties and a short-term change the flow of liquid to be evaporated no liquid exit.
Gegenstand der Erfindung ist weiterhin eine Verwendung des erfindungsgemäßen Flüssigkeitsverdampfers, die Gegenstand des Anspruchs 12 ist.object the invention furthermore relates to a use of the liquid evaporator according to the invention, which is the subject of claim 12.
Im Folgenden wird anhand der zugehörigen Zeichnung ein besonders bevorzugtes Ausführungsbeispiel der Erfindung näher beschrieben.in the The following is based on the accompanying drawing a particularly preferred embodiment closer to the invention described.
Die einzige Figur zeigt das Ausführungsbeispiel des erfindungsgemäßen Flüssigkeitsverdampfers in einer Schnittansicht.The single figure shows the embodiment the liquid evaporator according to the invention in a sectional view.

Es ist weiterhin vorteilhaft, in der Zuleitung für die zu verdampfende Flüssigkeit ein Rückschlagventil vorzusehen, um Druckwellenrückschläge in Folge von Dampfblasenbildung auf die Zuleitung zu vermeiden.It is also advantageous in the supply line for the liquid to be evaporated a check valve provide to pressure wave setbacks in a row to prevent the formation of steam bubbles on the supply line.
Der erfindungsgemäße Flüssigkeitsverdampfer kann nicht nur für Kraft- oder Brennstoffe, sondern auch für andere Flüssigkeiten wie Wasser, aber auch Harnstoff, eingesetzt werden, der bei einem Dieselkatalysator eines Dieselmotors zur Verbesserung der NOx-Absorption in die Abgasleitung eingebracht wird, was vorzugsweise über einen Harnstoffverdampfer erfolgt.Of the Liquid evaporator according to the invention not only for Fuels or fuels, but also for other liquids such as water, but Also, urea, used in a diesel catalyst a diesel engine to improve the NOx absorption introduced into the exhaust pipe what is preferably over a urea evaporator takes place.
Zu diesem Zweck ist eine Verdampfungsmenge von 0,5 bis 2 Liter Harnstoff pro Stunde erforderlich. Dieser Durchsatz ist bei dem erfindungsgemäßen Flüssigkeitsverdampfer gewährleistet.To For this purpose, an evaporation amount of 0.5 to 2 liters of urea required per hour. This throughput is in the case of the liquid evaporator according to the invention guaranteed.
Bei dem erfindungsgemäßen Flüssigkeitsverdampfer kann über eine lange Lebensdauer Harnstoff verdampft werden, ohne dass Flüssigkeit austritt oder sich der Verdampferraum durch Rückstände zusetzt. Bei einer Veränderung der Durchsatzmenge kann dementsprechend mit der Heizleistung nachgeregelt werden.at the liquid evaporator according to the invention can over A long life urea can be evaporated without any liquid exit or the evaporator compartment is added by residues. In a change The flow rate can be readjusted accordingly with the heating power become.
In
dieser Weise ist bei dem erfindungsgemäßen Flüssigkeitsverdampfer eine kompakte
Bauweise, beispielsweise mit einem Heizstabdurchmesser von 5 mm,
einem Einschraubgewinde M12 und einer Gesamtlänge von weniger als 100 mm
erreicht, die eine Verdampfung von Harnstoff ermöglicht. Durch die Verwendung
von Inconel für
