Die Erfindung hat eine Zerstäubungsvorrichtung zum Gegenstand, welche insbesondere·, aber nicht ausschließlich zur sofortigem Trocknung von Lösungen oder z. B. zum Spritzen mit Pistole oder zürn Abspritzen vorn Pflanzen mit zerstäubten Flüssigkeiten benutzt werden kann. Für diese Anwendungen muß die gespritzte Flüssigkeit in möglichst feine Tröpfchen zerteilt werden, um insbesondere die Überdeckung einer bestimmten Fläche mit einer ίο Minimalmenge der benutzten Flüssigkeit zu ermöglichen oder um eine fast augenblickliche Trocknung zu erreichen.The subject of the invention is an atomizing device which, in particular, but not exclusively for the immediate drying of solutions or z. B. can be used for spraying with a gun or zürn spraying in front of plants with atomized liquids. For these applications the sprayed liquid must be divided into as fine droplets as possible, in particular to reduce the To enable a certain area to be covered with a ίο minimum amount of the liquid used or to achieve almost instant drying. Es sind bereits Vorrichtungen dieser Art bekannt, welche einen mit eimer engen Öffnung versehenen Behälter aufweisen und in den die zu zerstäubende Flüssigkeit tangential zugeführt wird; diese Flüssigkeit nimmt dann eine kreisende Bewegung an und tritt aus. der ,öffnung in Form feinverteilter Tröpfchen aus;, es ist aber festgestellt worden, daß bei mittlerem oder schwachem Druck die dadurch erreichte Zerstäubung ungenügend ist.Devices of this type are already known which have a container with a narrow opening and into which the to be atomized Liquid is supplied tangentially; this liquid then assumes a circular motion and leave. the opening in the form of finely divided droplets from;, but it has been found that with medium or low pressure this reached Atomization is insufficient. Es ist auch vorgeschlagen worden;, Zerstäubungsvorrichtungen aus zwei gleichachsigen, mit tangentialen Einlaß versehenen Behälter herzustellen, wobei die Flüssigkeit in einen der Behälter unter einem hohen Druck von mehreren kg/cm? geschickt wird; durch ihr Entweichen- aus "der öffnung verursacht die Flüssigkeit einen Sog, die Luft entweicht dann ihrerseits durch die konzentrische Öffnung des zweiten Behältersi, so daß. bedeutend feinere Tröpfchen dadurch erreicht werden.It has also been proposed; atomizing devices composed of two equiaxed, with tangential Establish inlet provided container, the liquid in one of the containers under a high pressure of several kg / cm? is sent; When the liquid escapes from the opening, it creates a suction and the air then escapes in turn through the concentric opening of the second container, so that. significantly finer droplets can thereby be achieved. Die zuletzt beschriebene Vorrichtung ist aber auch nicht ohne Nachteile: Die Vorrichtding benötigt die Zuführung der Flüssigkeit unter hohem Druck, so daß die dazu notwendigen Druckerzeugungsmittel· vorgehalten werden müssen; außerdem ist die Ausspritzöffnung für die Flüssigkeit notwendigerweise eng, so daß die zerstäubte Menge ungenügend werden kann; endlich ist die durch' die Flüssigkeit her- -vorgerufene Sogwirkung nicht ausreichend, um eine zweckmäßige Zerteilung der Tröpfchen'zu bewirken. Die Vorrichtung nach der Erfindung weist diese Nachteile nicht auf. DieZerstäubungsvorrichtung besteht aus zwei gleichachsig ineinander angeordneten, mit tangentialen und einander entgegengesetzt gerichteten Einführungsleitungen versehenen Kammern. Der inneren [Kammer wird die zu zerstäubende Flüssigkeit ohnie Druck und der äußeren Kammer Druckluft zugeführt. Die am entgegengesetzten Ende befindliche Düsenöffnungen 5, 10 der vorzugsweise aus einem zylindrischen und einem konischen Teil bestehenden beiden Kammern 1, 6 sind gleichachsig angeordnet und liegen in derselben Ebene oder nahezu derselben Ebene.The device last described is also not without disadvantages: the Vorrichtding requires the supply of the liquid under high pressure, so that the necessary pressure generating means must · be kept available; also is the ejection opening for the liquid necessarily narrow, so that the atomized amount becomes insufficient can; Finally, the suction effect caused by the liquid is not sufficient to create a appropriate division of the droplets' to bring about. The device according to the invention has this Disadvantages do not arise. The atomization device consists of two coaxially arranged one inside the other, chambers provided with tangential and oppositely directed introduction lines. The inner [chamber becomes the one to be atomized Liquid without pressure and compressed air supplied to the outer chamber. The one on the opposite end located nozzle openings 5, 10, which preferably consists of a cylindrical and a conical Part of the existing two chambers 1, 6 are coaxial arranged and are in the same plane or almost the same plane. Diese Vorrichtung wird auch vorteilhaft für Zerstäubungebrenner angewendet und kann im allgemeinen für alle Flüssigkeitszerstäubungen benutzt werden. ~This device also becomes advantageous for atomizing burners and can generally be used for all liquid atomization. ~ In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.An exemplary embodiment of the subject matter of the invention is shown in the drawing. Abb. ι stellt einen Axialschnitt einer Vorrichtung nach der Erfindung dar;Fig. Ι represents an axial section of a device according to the invention; Abb. 2 ist eine Draufsicht auf eine Vorrichtung nach Abb. 1.FIG. 2 is a top plan view of an apparatus according to FIG. 1. In der in den Abb. 1 und 2 dargestellten Ausführungsform weist die Vorrichtung eine erste, durch einen zylindrischen Teil 2 und einen kegelförmigen Teil 3 gebildete Kammer r auf; dieser Kammer wird die zu zerstäubende Flüssigkeit durch die Leitung 4 zugeführt, die, wie die Abb. 2 zeigt, tangential zum zylindrischen Teil 2 der Kammer 1 angelegt ist. Der kegelförmige Teil 3 endet in einer kreisförmigen Öffnung 5.In the embodiment shown in Figs the device has a first, by a cylindrical part 2 and a conical part Part 3 formed chamber r on; this chamber will the liquid to be atomized fed through the line 4, which, as Fig. 2 shows, tangential to the cylindrical part 2 of the chamber 1 is applied. The conical part 3 ends in a circular one Opening 5. Gleichachsig zur Kammer 1 ist um diese herum eine zweite, auch einen zylindrischen Teil 7 und einen kegelförmigen Teil 8 aufweisende Kammer 6 angeordnet; in diesen zylindrischen Teil 7 mündet die Luftleitung 9, welche, wie die Abb. 2 zeigt, gleichfalls tangential zum zylindrischen Teil 7 angeordnet ist. Der kegelförmige Teil 8 der Kammer 6 endet in einer öffnung 10, welche kreisringförmig und konzentrisch zu der öffnung 5 ist.Coaxial with the chamber 1 is a second, also a cylindrical part 7 and around it a conical part 8 having chamber 6 arranged; opens into this cylindrical part 7 the air line 9, which, as FIG. 2 shows, is also arranged tangentially to the cylindrical part 7 is. The conical part 8 of the chamber 6 ends in an opening 10, which is circular and is concentric to the opening 5. Die eben beschriebene Vorrichtung wirkt folgendermaßen: The device just described works as follows: Die Luft wird unter schwachem Druck durch die Leitung 9 der Kammer 6 zugeführt und nimmt darin eine, kreisende Bewegung an, die durch die Pfeile F angedeutet ist. Sie saugt die in dieJEammer ι durch die Leitung 4 eindringende Flüssigkeit an, die selbst eine durch die Pfeile f angedeutete Kreisbewegung 90 " annimmt!. " * ■The air is supplied under low pressure through the line 9 to the chamber 6 and assumes a circular movement therein, which is indicated by the arrows F. It sucks in the liquid which penetrates into the chamber through the line 4 and which itself assumes a circular movement 90 "indicated by the arrows f!" * ■ In der dargestellten Aüsführungsform sind die Leitungen 4 und 9 derart angeordnet, daß die Luft und die Flüssigkeit entgegengesetzt kreisende Bewegungen, wie durch die PfeileF und/ angezeigt, annehmen. Infolgedessen wird die Flüssigkeit ganz besonders wirksam zerstäubt. *In the embodiment shown, the lines 4 and 9 are arranged in such a way that the air and the liquid assume opposing circular movements, as indicated by the arrows F and /. As a result, the liquid is atomized particularly effectively. * PATENTANSBRUCH:PATENT BREAKDOWN: Zerstäubungsvorrichtung, bestehend aus zwei gleichachsig ineinander angeordneten, mit tangentialen und einander entgegengesetzt gerichteten Zuführungsleitungen versehenen Kammern, dadurch gekennzeichnet, daß. der inneren Kammer (1) die zu zerstäubende Flüssigkeit ohne Druck und der äußeren Kammer (6) Druckluft zugeführt wird und daß die am entgegengesetzten Ende befindlichen Düsenöffnungeni (5, 10) der -. vorzugsweise aus einem zylindrischen und einem konischen Teil bestehenden beiden Kammern (1, "» 6) gleichachsig angeordnet sind und in oder nahezu in derselben Ebene liegen.Atomizing device, consisting of two coaxially arranged one inside the other, with tangential and oppositely directed supply lines provided chambers, characterized in that. the inner chamber (1) the liquid to be atomized without Pressure and the outer chamber (6) compressed air is supplied and that the nozzle openings located at the opposite end (5, 10) of the -. preferably consisting of a cylindrical and a conical part two chambers (1, "» 6) are coaxially arranged and lie in or almost in the same plane.
