, Sprühdüse für flüssige Medien., Spray nozzle for liquid media.
Sprühdüsen üblicher Bauart weisen einen Hauptdüsenkörper für das gasförmige Medium auf, in dessen Inneren sich die Düse für das flüssige Medium befindet. Die Innendüse befindet vor der Austrittsbohrung im Inneren des Hauptdüsenkörpers und ist nicht koaxial in ihm befestigt.Spray nozzles of the usual design have a main nozzle body for the gaseous medium, inside which is the nozzle for the liquid medium. The inner nozzle is located in front of the outlet hole inside the main nozzle body and is not attached coaxially to it.
Das flüssige Medium wird mit Hilfe des gasförmigen Mediums nach dem Injektionspnnzip im Inneren des Hauptdüsenkörpers vernebelt und tritt an der Hauptdüsenbohrung aus.The liquid medium is nebulized with the help of the gaseous medium according to the injection principle inside the main nozzle body and exits at the main nozzle bore.
Der Nachteil dieser üblichen Bauart besteht darin, daß sich durch dieses Düsenprinzip kein gleichmäßiger reproduzierbarer, mikrofeiner Sprühkegel erzeugen läßt.The disadvantage of this conventional design is that this nozzle principle does not produce a uniform, reproducible, microfine spray cone.
Ein weiterer Nachteil besteht darin, daß sich bei Nichtbenutzung der Sprühdüse im Hauptdüsenkörper Tröpchen des flüssigen Mediums bilden und dadurch bei Inbetnebnahme der Sprühdüse sich anfangs ein Undefinierter Sprühkegel bildet, welcher sich erst nach einer Anlaufphase normalisiert. A further disadvantage is that when the spray nozzle is not in use, droplets of the liquid medium form in the main nozzle body and as a result, when the spray nozzle is put into operation, an undefined spray cone is initially formed, which only normalizes after a start-up phase.
Der im Schutzanspruch 1-2 angegebenen Erfindung liegt das Problem zugrunde, eine Sprühdüse zu entwickeln, mit der sich ein gleichmäßiger, optimal reproduzierbarer, mikrofeiner Sprühkegel erzeugen läßt, welcher ohne Anlaufphase bei Inbetriebnahme der Sprühdüse vorhanden ist.The invention specified in claims 1-2 is based on the problem of developing a spray nozzle with which a uniform, optimally reproducible, microfine spray cone can be produced, which is present without a start-up phase when the spray nozzle is put into operation.
Dieses Problem wird mit den im Schutzanspruch 1-2 aufgerührten Merkmalen gelöst.This problem is solved with the features set out in claims 1-2.
Mit der Erfindung wird erreicht, daß durch die koaxiale Positionierung der inneren Düse unter Verwendung einer Zentrierhülse und deren Überstand zur Austrittsbohrung des Hauptdüsenkörpers ein gleichmäßiger, optimal reproduzierbarer, mikrofeiner Sprühkegel entsteht, welcher bei Inbetriebnahme der Sprühdüse sofort ohne Anlaufphase vorhanden ist.The invention achieves that the coaxial positioning of the inner nozzle using a centering sleeve and its projection to the outlet bore of the main nozzle body creates a uniform, optimally reproducible, microfine spray cone, which is immediately present when the spray nozzle is put into operation without a start-up phase.
