Description

Zum Zerstäuben von Flüssigkeiten sind bereits Einrichtungen mannigfacher Art .bekannt. Es ist auch bekannt, Flüssigkeiten mittels Schall- oder Ultraschallschwingungen zu zerstäuben. Die Erfindung betrifft eine Einrichtung zum Zerstäuben von Flüssigkeiten, mittels Schall- oder Ultraschallschwingungen, .die sich durch besonders große Leistungs- und Widerstandsfähigkeit auszeichnet. Bei der Einrichtung nach der Erfindung wird -als Schwingungserzeuger ein Hartmann-Generator verwendet, und zwar erfindungsgemäß derart, daß Mittel vorgesehen sind, beispielsweise ein Rohr, die die zu zerstäubende Flüssigkeit dem Hartmann-Generator in dem Raum zwischen Düse und Resonator zuführen. Besonders vorteilhaft ist es, die .die Flüssigkeit zuführenden Mittel derart anzuordnen, daß die Flüssigkeit in den Raum zwischen Düse und Resonator in einem Bereich resultierenden Unterdruckes eintritt. Ein resultierenderUnterdruck entsteht un den Druckknoten der stehenden Welle, also an den .Stellen maximaler ,Schwingbewegung. An Hand eines in der Zeichnung .dargestellten Ausführungsbeispiels sei die Einrichtung nach der Erfindung erläutert.Devices for atomizing liquids are already manifold Art. Known. It is also known to vibrate liquids by means of sonic or ultrasonic vibrations to atomize. The invention relates to a device for atomizing liquids, by means of sonic or ultrasonic vibrations, which are characterized by particularly high power and resilience. In the device according to the invention -A Hartmann generator used as a vibration generator, according to the invention such that means are provided, for example a tube, which is to be atomized Feed the liquid to the Hartmann generator in the space between the nozzle and the resonator. It is particularly advantageous to arrange the means supplying the liquid in such a way that that the liquid in the space between the nozzle and resonator in an area resulting Negative pressure occurs. A resulting negative pressure arises at the pressure knot the standing wave, i.e. at the points of maximum, oscillating movement. On the basis of one In the drawing, the embodiment shown is the device according to the Invention explained.

Eine Düse r und ein Hohlraumresonator 2 stellen in bekannter Weise einen Hartmann-Generatordar. Durch die Düse r wird Luft oder ein anderes Gas in den Resonator 2 mit Überschallgeschwindigkeit hineingeblasen, so daß die Luftsäule in dem Resonator und in dem Zwischenraum zwischen Düse und Resonator in bekannter Weise in Schall- oder Ultraschallschwingungen gerät. Erfindungsgemäß ist ein Rohr 3 vorgesehen, durch das die zu zerstäubende Flüssigkeit in den Raum zwischen Düse und Resonator hineingeführt wird. Unterhalb !der Teile z und 2 ist,die bekannte Pitot-Kurve 4 eingezeichnet, die den statischen Druck in,dem Raum zwischen Düse und Resonator anzeigt, also den resultierenden Druck. Wie -aus der Zeichnung ersichtlich, ist .das Rohr 3 derart angeordnet, daß idie Flüssigkeit in den Raum zwischen Düse und Resonator in dem mit 5 bezeichneten Unterdruckbereich eintritt.A nozzle r and a cavity resonator 2 represent in a known manner a Hartmann generator. Air or another gas is drawn in through the nozzle r the resonator 2 blown in at supersonic speed, so that the air column in the resonator and in the space between nozzle and resonator in a known manner Way in sonic or ultrasonic vibrations. According to the invention is a pipe 3 provided through which the liquid to be atomized into the space between the nozzle and resonator is introduced. Below! The parts z and 2 is the known one Pitot curve 4 is drawn showing the static pressure in, the space between the nozzle and resonator, i.e. the resulting pressure. As can be seen from the drawing, is .das tube 3 arranged in such a way that i the liquid in the space between the nozzle and resonator in the negative pressure area designated by 5 enters.
