Abstract

Part of the fluid delivered by the pump (1) is branched off and used to drive a piston pump (12). This pump (12) is coupled to a compressor (17) or highpressure pump and in this way produces compressed air or highpressure fluid. Components in the flow include branch point tee-piece (5) and control valve (6) which uses an adjuster (7) to pass the branched fluid to the jet (8). The main flow is routed along pressure lines (10,11) to the piston pump (12) whose piston rod (15) is coupled to the compressor piston (16,17).

Description

Stand der TechnikState of the art

Es besteht der Trend, die Zerstäubungsgüte bei Verbrennungseinrichtungen für flüs­ sige Brennstoffe zu verbessern. Um dieses Ziel zu erreichen, sind zwei Verfahren möglich. Zunächst ist bekannt, die Zerstäubung mittels Druckluft durchzuführen. Die üblichen Kompressoren sind aber relativ groß und teuer. Die andere Möglichkeit be­ steht darin, den Zerstäubungsdruck des Brennstoffs deutlich anzuheben.There is a trend towards the atomization quality in combustion devices for rivers sige fuels to improve. There are two ways to achieve this goal possible. First of all, it is known to carry out the atomization by means of compressed air. The Common compressors are relatively large and expensive. The other way be is to raise the atomization pressure of the fuel significantly.

Serienmäßig gibt es jedoch für beide Verfahren keine preiswerten Pumpen und Luft­ verdichter. Ein Ölbrenner müsste z. B. mit einem wesentlich größeren Elektromotor ausgerüstet werden, um einen Kompressor oder eine Hochdruckölpumpe anzutrei­ ben. Unter Umständen wäre sogar ein zusätzlicher Motor erforderlich, was die Kos­ ten für solche Geräte drastisch erhöhen würde.However, there are no inexpensive pumps and air for both processes as standard compressor. An oil burner would need e.g. B. with a much larger electric motor be equipped to drive a compressor or a high pressure oil pump ben. Under certain circumstances, an additional engine would be required, which the Kos would drastically increase for such devices.

Aufgabe der ErfindungObject of the invention

Der Erfindung liegt die Aufgabe zugrunde, mit einem einfachen Verfahren kosten­ günstig beide Varianten zur Verbesserung der Zerstäubung zu ermöglichen.The invention has for its object to cost with a simple method cheap to enable both variants to improve the atomization.

Das Verfahren macht es möglich, auf preiswerte Art und Weise Druckluft zu erzeu­ gen, oder einen wesentlich höheren Flüssigkeitsdruck zu erzielen. The object is achieved by the characterizing features of the main claim. The process makes it possible to produce compressed air in an inexpensive manner gene, or to achieve a much higher fluid pressure.

Beschreibung des ErfindungsbeispielsDescription of the invention example

Nachstehend ist das Schema beschrieben, mittels des in größerer Menge geförder­ ten Brennstoffs eine zusätzliche Kolbenpumpe zu betreiben, mit angekoppeltem Kompressor zur Drucklufterzeugung, insbesondere bei Ölbrennern. Brenner dieser Bauart, und auch solche, wie sie bei Gasturbinen verwendet werden, oder auch Ver­ brennungsmotoren, sind in der Regel mit einer Kraftstoffpumpe ausgestattet. Diese Pumpen sind in der Lage, eine große Menge Fluid anzusaugen und auf den erforder­ lichen Zerstäubungsdruck zu bringen. So hat z. B. die Pumpe eines Ölbrennerns kleiner Leistung bei 10 bar Zerstäubungsdruck eine Düsenleistung von ca. 25 l/h, ob­ wohl vielleicht nur 1,5 l/h für die Verbrennung benötigt werden. Dieses überschüssi­ ge Drucköl steht zur Verfügung, um entweder einen Kompressor anzutreiben, wel­ cher z. B. 250 l/h Druckluft von 1 bar erzeugt, oder auch eine Hochdruckölpumpe, welche 1 l/h Heizöl mit ca. 200 bar fördert. Auf diese Weise ist es möglich, mit dem beschriebenen Verfahren ohne großen technischen Aufwand die benötigte Menge Druckluft zu erzeugen, oder auch einen wesentlich höheren Öldruck. Dadurch kön­ nen auch Einstoffdüsen ein deutlich feineres Tropfenspektrum bilden, als dies bei den üblichen Zerstäubungsdrücken von 10-15 bar der Fall ist.Below is a description of the scheme by means of which is funded in large quantities ten fuel to operate an additional piston pump, with coupled Compressor for generating compressed air, especially for oil burners. Burner this Design, and also those used in gas turbines, or Ver internal combustion engines are usually equipped with a fuel pump. This Pumps are able to draw a large amount of fluid and to the required bring atomization pressure. So z. B. the pump of an oil burner low output at 10 bar atomization pressure a nozzle output of approx. 25 l / h, whether maybe only 1.5 l / h are needed for the combustion. This surplus Pressure oil is available to either drive a compressor, which cher z. B. 250 l / h of compressed air of 1 bar, or a high pressure oil pump, which pumps 1 l / h heating oil at approx. 200 bar. This way it is possible to use the described method without much technical effort the required amount To generate compressed air, or a much higher oil pressure. This allows single-component nozzles also form a much finer drop spectrum than this the usual atomization pressures of 10-15 bar is the case.

Die Zeichnung zeigt schematisch die Ölpumpe 1 mit der Saugleitung 2, der Drucklei­ tung 3 und der Rücklaufleitung 4. Die Druckleitung 3 ist mit dem T-Stück 5 versehen, wodurch eine Abzweigung zum Steuerventil 6 und dem Stellglied 7 zustande kommt. Über das Stellglied 7 wird ein geringer Teilstrom des von der Ölpumpe 1 geförderten Brennstoffs der Düse 8 zugeführt. Der Hauptstrom gelangt über den Anschluss 9 zum Steuerventil 6, welches über die Druckleitungen 10 und 11 zu der doppelt wir­ kenden hydraulischen Kolbenpumpe 12 führt. Der von der Pumpe 1 geförderte Brennstoff treibt über das Steuerventil 6 die Kolbenpumpe 12 an. Abwechselnd wird die Verbindung zwischen dem Steuerventil 6 und der Kolbenpumpe 12 über die Druckleitungen 10 und 11, sowie den Rücklaufleitungen 13 und 14 hergestellt. Der mit der Kolbenstange 15 verbundene Kolben 16 des Luftverdichters 17 fördert bei der Bewegung der Kolbenpumpe 12 Druckluft zur Düse 8. Über die Leitungen 18 und den hier nicht dargestellten Ansaugventilen wird die Luft angesaugt, über die Leitungen 19 wird die Druckluft zur Düse 8 gefördert. Die Druckventile sind wegen der besseren Übersichtlichkeit ebenfalls nicht dargestellt.The drawing shows schematically the oil pump 1 with the suction line 2 , the Drucklei device 3 and the return line 4th The pressure line 3 is provided with the T-piece 5 , whereby a branch to the control valve 6 and the actuator 7 is achieved. A small partial flow of the fuel delivered by the oil pump 1 is fed to the nozzle 8 via the actuator 7 . The main flow passes through the connection 9 to the control valve 6 , which leads via the pressure lines 10 and 11 to the double-acting hydraulic piston pump 12 . The fuel delivered by the pump 1 drives the piston pump 12 via the control valve 6 . The connection between the control valve 6 and the piston pump 12 is alternately established via the pressure lines 10 and 11 and the return lines 13 and 14 . The piston 16 of the air compressor 17 connected to the piston rod 15 conveys compressed air to the nozzle 8 when the piston pump 12 moves. The air is drawn in via the lines 18 and the suction valves (not shown here), and the compressed air is conveyed to the nozzle 8 via the lines 19 . The pressure valves are also not shown for better clarity.

Bei der Verwendung von Hochdruckdüsen bleibt die hydraulisch angetriebene Kol­ benpumpe gleich. Anstatt des Luftverdichters wird eine Hochdruckkolbenpumpe vor­ gesehen, welche mit einem wesentlich kleinerem Kolben ausgestattet ist als dies beim antreibenden Koben der Fall ist.When using high-pressure nozzles, the hydraulically driven piston remains  ben pump the same. Instead of the air compressor, a high-pressure piston pump is used seen, which is equipped with a much smaller piston than this is the case with driving koben.

In der beschriebenen Weise kann das überschüssige Fluid der Brennstoffförderpum­ pe die Kraftquelle sein, um die gestellten Aufgaben zu bewältigen.In the manner described, the excess fluid of the fuel pump can pe be the source of strength to master the tasks.
