Description

Die Erfindung betrifft ein Vernebelungsgerät mit einer vorzugsweise eine Durchflußrate von 1 bis 10 Liter/Stunde aufweisenden und vorzugsweise Tröpfchen mit einem Durchmesser von weniger als 150 µm aussprühenden Düse zur Zerstäubung einer Flüssigkeit die eine Düsenbohrung - vorzugsweise mit einem Durchmesser von weniger als 2 mm, bevorzugt 0,6 mm bis 0,8 mm - aufweist.The invention relates to a nebulizer with a preferably having a flow rate of 1 to 10 liters / hour and preferably spraying droplets with a diameter of less than 150 microns for atomizing a liquid which has a nozzle bore - preferably with a diameter of less than 2 mm, preferably 0.6 mm to 0.8 mm.

Werden mit solchen Vernebelungsgeräten verhältnismäßig viskose Flüssigkeiten, insbesondere Suspensionen zerstäubt, so verstopft sich die der Zerstäubung dienende Düse häufig, was insbesondere bei einer automatischen Steuerung des Vernebelungsgerätes lästig ist. Es müssen regelmäßige Zwischenreinigungen der Düse bei Unterbrechung des automatischen Betriebs erfolgen. Meist dient zur Reinigung der Düse Wasser, für das ein gesonderter Wassertank vorgesehen sein muß. Dennoch treten häufig Blockierungen der Düse mit Schmutzpartikeln auf, die Störungen verursachen.If relatively viscous liquids, in particular suspensions, are atomized with such nebulizing devices, the atomizing nozzle is often blocked, which is particularly troublesome when the nebulizing device is controlled automatically. Regular interim cleaning of the nozzle must be carried out when the automatic operation is interrupted. Water is usually used to clean the nozzle, for which a separate water tank must be provided. Nevertheless, there are often blockages of the nozzle with dirt particles that cause malfunctions.

Aufgabe der Erfindung ist es, Störungen durch Verstopfung der Düse zu vermeiden.The object of the invention is to eliminate disorders caused by constipation To avoid nozzle.

Zur Lösung dieser Aufgabe ist das Vernebelungsgerät dadurch gekennzeichnet, daß in der Düsenbohrung wenigstens eine Leitung mündet, durch die im Betriebszustand der Düse Gas, insbesondere Luft, in die Düsenbohrung gesaugt wird, und daß der Leitung ein Stellventil zur Einstellung der Rate dieses Gases, insbesondere der Luft, zugeordnet ist.To solve this problem, the nebulizer is characterized in that at least one line opens into the nozzle bore through which gas, in particular air, is sucked into the nozzle bore when the nozzle is in operation, and that the line has a control valve for adjusting the rate of this gas, in particular the air.

Daß der Düse zugeordnete Gas, also insbesondere die Luft, nimmt die der Düse zugeführte Flüssigkeit mit und verhindert ein Verstopfen der Düse durch die Flüssigkeit.The gas associated with the nozzle, in particular the air, takes the liquid supplied to the nozzle with it and prevents the nozzle from being blocked by the liquid.

Bei Ausführung der Erfindung kann die Düsenbohrung verhältnismäßig groß sein und einen über ihre Länge gleichbleibenden Querschnitt aufweisen, der praktisch keinen Anlaß zur Verstopfungen ergibt. Durch das Stellventil kann die Durchflußgeschwindigkeit des Flüssigkeits-Gas-Gemisches, also insbesondere des Flüssigkeits-Luft-Gemisches, gesteuert werden.In carrying out the invention, the nozzle bore can be relatively large and have a cross section which is constant over its length and which gives practically no cause for blockages. The flow rate of the liquid-gas mixture, in particular the liquid-air mixture, can be controlled by the control valve.

Einer im Sinne der Aufgabe der Erfindung besonders wirksame konstruktive Lösung ist dadurch gekennzeichnet, daß sich in der Düse ein die Düsenbohrung umschließender Ringraum befindet, in dem die Leitung zur Zuführung des Gases, insbesondere der Luft, mündet und von dem schräg in Richtung zu einem Endabschnitt der Düsenbohrung ein Kranz von in der Düsenbohrung mündenden Seitenbohrungen ausgeht.A constructive solution which is particularly effective in the sense of the object of the invention is characterized in that in the nozzle there is an annular space enclosing the nozzle bore, in which the line for supplying the gas, in particular the air, opens and from which obliquely towards an end section the nozzle bore starts with a ring of side bores opening into the nozzle bore.

Um die Menge des zugeführten Gases einstellen zu können ist bevorzugt vorgesehen, daß das Stellventil ein von Hand einstellbares Nadelventil ist.In order to be able to adjust the amount of gas supplied, it is preferably provided that the control valve is a manually adjustable needle valve.

Zur automatischen Steuerung ist bevorzugt vorgesehen, daß an die der Düse Gas, insbesondere Luft, zuführenden Leitung und/oder an eine der Düse die Flüssigkeit zuführenden Leitung ein Druckmeßgerät angeschlossen ist. Signale des Druckmeßgeräts bzw. der Druckmeßgeräte werden einer Steuerung zugeführt, die die automatische Betriebsweise der Vorrichtung gestattet.For automatic control it is preferably provided that a pressure measuring device is connected to the line supplying gas, in particular air, and / or to a line supplying the liquid to the nozzle. Signals of the pressure measuring device or the pressure measuring devices are fed to a controller which the automatic operation of the device allows.

Dem gleichen Zweck dient auch die Ausbildung, daß das Ventil von einem Durchflußsensor gesteuert ist, der auf die Rate der der Düsenbohrung zugeführten Flüssigkeit anspricht.The same purpose also serves the training that the valve is controlled by a flow sensor which responds to the rate of the liquid supplied to the nozzle bore.

Bevorzugt ist ein - insbesondere von dem Durchflußsensor gesteuertes - Regelgerät vorgesehen, das die Viskosität des der Düsenbohrung 10 zugeführten Flüssigkeits-Gas-Gemisches oder die Durchflussrate des Gemisches durch die Düsenbohrung 10 durch entsprechende Steuerung des Ventils 28 im wesentlichen konstant hält und/oder das eine willkürliche Einstellung der Durchflussrate des Gemisches durch die Düsenbohrung 10 gestattet.A control device, which is controlled in particular by the flow sensor, is preferably provided, which keeps the viscosity of the liquid-gas mixture supplied to the nozzle bore 10 or the flow rate of the mixture through the nozzle bore 10 essentially constant by appropriately controlling the valve 28 and / or the one arbitrary adjustment of the flow rate of the mixture through the nozzle bore 10 allowed.

Die Erfindung wird im folgenden an einem Ausführungsbeispiel unter Hinweis auf die beigefügte Zeichnung beschrieben.The invention is described below using an exemplary embodiment with reference to the accompanying drawings.

Die Zeichnung zeigt eine Düse 2, die der Zerstäubung einer Flüssigkeit 4 dient, die ihr aus einem Tank 6 über eine Leitung 8 zugeführt wird.The drawing shows a nozzle 2, which is used to atomize a liquid 4, which is supplied to it from a tank 6 via a line 8.

Die Düse 2 weist zu diesem Zweck eine Düsenbohrung 10 auf, die sich in einen Endabschnitt 12 konisch erweitert. Der Endabschnitt ist von einer Zerstäuberdose 14 mit einem Wirbelstrom erzeugenden Lamellen 16 umschlossen. Einem stromaufwärtigen radial äußeren Ringbereich 18 der Zerstäuberdose 14 wird in Richtung der Pfeile 20 aus einem Kompressor Druckluft zugeführt. Diese Druckluft tritt vor dem Endabschnitt 12 der Düse 2 durch ein Loch 22 in einen Deckel 24 der Zerstäuberdose 14 aus und übt auf den Endabschnitt 12 der Düsenbohrung 10 einen Sog aus. Durch Steuerung des von dem Kompressor abgegebenen Drucks kann man die Durchflussrate durch die Düse 2 steuern.For this purpose, the nozzle 2 has a nozzle bore 10 which widens conically into an end section 12. The end section is enclosed by an atomizer can 14 with lamellae 16 which generate eddy current. Compressed air is supplied to an upstream radially outer ring region 18 of the atomizer can 14 in the direction of the arrows 20 from a compressor. This compressed air exits the end section 12 of the nozzle 2 through a hole 22 in a cover 24 of the atomizer can 14 and exerts a suction on the end section 12 of the nozzle bore 10. The flow rate through the nozzle 2 can be controlled by controlling the pressure delivered by the compressor.

In der Düsenbohrung 10 mündet in noch zu beschreibender Weise eine Leitung 26, durch die im Betriebszustand der Düse 2 Gas, insbesondere Luft, in die Düsenbohrung 10 gesaugt wird. Das Gas, insbesondere die Luft, kann zur Verbesserung der Vernebelung und/oder der Reinigung der Düse 2 erwärmt sein. In der Leitung befindet sich ein Nadelventil mit einer Nadel 30, deren axiale Lage durch einen Drehgriff 32 zu verstellen ist. In das Nadelventil wird Gas, insbesondere Luft, in Richtung des Pfeils 34 eingesaugt. In der Düse 2 befindet sich ein die Düsenbohrung 10 umschließender Ringraum 36 in dem die Leitung 26 zur Zuführung des Gases, insbesondere der Luft, radial zur Düsenbohrung 10 gerichtet mündet. Von dem Ringraum 36 geht schräg in Richtung zum Endabschnitt 12 der Düsenbohrung 10 ein Kranz von in der Düsenbohrung 10 mündenden Schrägbohrungen 38 aus.In the nozzle bore 10, a line 26 opens in a manner to be described, through which gas, in particular air, is sucked into the nozzle bore 10 when the nozzle 2 is in operation. The gas, especially the air, can help improve nebulization and / or cleaning the nozzle 2. In the line there is a needle valve with a needle 30, the axial position of which can be adjusted by means of a rotary handle 32. Gas, in particular air, is sucked into the needle valve in the direction of arrow 34. In the nozzle 2 there is an annular space 36 which surrounds the nozzle bore 10 and in which the line 26 for supplying the gas, in particular the air, opens radially to the nozzle bore 10. A ring of oblique bores 38 opening into the nozzle bore 10 extends obliquely from the annular space 36 towards the end section 12 of the nozzle bore 10.

Sowohl an die Leitung 8 als auch an die Leitung 26 ist je ein Druckmeßgerät 40 angeschlossen.A pressure measuring device 40 is connected to both the line 8 and the line 26.
