Abstract

Vorrichtung zum Ausbringen von Flüssigkeit (2) in Form von elektrisch aufgeladenen Tropfen über ein Spritzsystem, z. B. eine rotierende Scheibe (7), aus einem Vorratsbehälter (1), wobei der Vorratsbehälter (1) und alle Einrichtungen zur Förderung der Flüssigkeit (2), wie Pumpe (3) und Absperr­ ventil (4) ungeladen sind, dadurch gekennzeichnet, daß
a) die Flüssigkeit (2) in Form von Tröpfchen oder in einem intermittierenden Strahl, z. B. durch eine Düse (5), über eine Luftstrecke (6) von 3 bis 30 cm, vorzugsweise von 5 bis 20 cm, auf eine rotierende Scheibe (7) gefördert wird,
b) an der rotierenden Scheibe (7) Hochspannung von 10 bis 150 kV, vorzugsweise von 50 bis 100 kV, angelegt ist,
c) die Flüssigkeit an der rotierenden Scheibe (7) aufgela­ den und abgeschleudert wird und
d) das Gehäuse des Rotationszerstäubers (11) so aus­ gebildet ist, daß elektrische Kraftwirkungen auf Personen oder benachbarte Anlagenteile verhindert werden. Device for dispensing liquid (2) in the form of electrically charged drops via a spray system, e.g. B. a rotating disc (7) from a storage container (1), the storage container (1) and all devices for conveying the liquid (2), such as pump (3) and shut-off valve (4) are uncharged, characterized in that that
a) the liquid (2) in the form of droplets or in an intermittent jet, e.g. B. is conveyed through a nozzle (5), over an air gap (6) of 3 to 30 cm, preferably from 5 to 20 cm, onto a rotating disc (7),
b) high voltage of 10 to 150 kV, preferably of 50 to 100 kV, is applied to the rotating disk (7),
c) the liquid on the rotating disc (7) is charged and flung and
d) the housing of the rotary atomizer (11) is formed in such a way that electrical force effects on people or neighboring system parts are prevented.
