Verfahren und Vorrichtung zum Zerstäuben von FlüssigkeitenMethod and device for atomizing liquids
Es ist bekannt, flüssige· Stoffe mit einem gas- oder dampfförmigen Druckmittel zu zerstäuben. Nach einer noch nicht bekanntgemachten Patentanmeldung B 73 814 Ib/49 1»3 wird hierbei ein Gas durch eine sich kegelförmig verjüngende Kammer tangential mit Drall gegen den senkrecht nach unten ablaufenden Strahl des flüssigen Stoffes geführt. Es ist ferner bekannt, den im Ablaufweg des flüssigen Stoffes angeordneten Düsenkörper zu erwärmen. Diese Heizung kann als Gasheizung, elektrische Widerstandsheizung oder Induktionsheizung eingerichtet sein, wobei letztere sehr wirkungsvoll ist. Nachteilig bei diesen bekannten Heizungsarten ist die Unmöglichkeit, den Düsenkörper in seiner ganzen Länge gleichmäßig zu beheizen, vor allem kann die Spitze des Düsenkörpers nicht beheizt werden.It is known to combine liquid · substances with a gaseous or vaporous To atomize pressure medium. According to a not yet published patent application B 73 814 Ib / 49 1 »3, a Gas through a cone-shaped tapering chamber tangentially with a twist against the perpendicular downward jet of the liquid substance. It is also known to close the nozzle body arranged in the drainage path of the liquid substance heat. This heater can be set up as a gas heater, electrical resistance heater or induction heater, with the latter is very effective. The disadvantage of these known types of heating is the impossibility of removing the nozzle body to be heated evenly over its entire length, especially the tip of the nozzle body cannot be heated.
