Description
Vorrichtung zum Zerteilen von Gasen in Flüssigkeiten Bei der Abwasserreinigung mit anorganischen Katalysatoren und Luft wie auch bei der Paraffinoxydation durch Sauerstoff enthaltende Gase, bei der Hefebelüftung, bei der Flotation usw. kommt es darauf an, große Gasmengen in feiner Verteilung in die Flüssigkeit zu bringen und gleichzeitig für eine gute Durchmischung zu sorgen. Dabei tritt der überstand ein, daß das Gas an die Rührvorrichtung gelangt und dadurch deren Wirksamkeit stark herabsetzt.Device for dividing gases into liquids in wastewater treatment with inorganic catalysts and air as well as with paraffin oxidation Oxygen-containing gases, where yeast aeration, flotation, etc. come it is important to bring large amounts of gas in fine distribution into the liquid and at the same time to ensure good mixing. The protrusion occurs one that the gas reaches the stirrer and thereby its effectiveness is strong belittles.
Dieser Nachteil wird gemäß der Erfindung dadurch vermieden, daß der z. B. von einer Umwälzschraube durch ein lotrecht angeordnetes Leitrohr von oben nach unten geförderte Flüssigkeitsstrom gegen die Spitze eines unterhalb der Umwälzschraube angeordneten Prall bleches gefördert wird, an dem die Flüssigkeitsströmung umbiegt und alle Gasblasen mitnimmt. Die Gaszufuhr erfolgt zweckmäßig durch Öffnungen in dem kegelförmigen Prallblech, die gegebenenfalls derart ausgebildet sind, daß an der Gaszuführungsstelle ein Venturieffekt auftritt. Damit keine Luftblasen zu der die Umwälzung bewirkenden Schraube gelangen können, werden die Öffnungen in dem kegelförmigen Prallblech außerhalb der lotrechten Projektion des die Umwälzschraube umgebenden Rohres auf das Prallblech angeordnet. Der aus dem Rohr austretende Flüssigkeitsstrom trifft also zunächst auf den oberen Teil der Prallfläche, die nicht durchlöchert ist, und strömt dann erst an den Luftzufuhröffnungen vorbei. This disadvantage is avoided according to the invention in that the z. B. from a circulation screw through a vertically arranged guide tube from above downward flow of liquid against the top of one below the circulating screw arranged baffle plate is promoted, on which the liquid flow bends and takes all the gas bubbles with it. The gas is expediently supplied through openings in the conical baffle plate, which are optionally designed such that on a Venturi effect occurs at the gas supply point. So that there are no air bubbles the circulation causing screw can get, the openings in the conical baffle outside the perpendicular projection of the circulation screw surrounding pipe arranged on the baffle plate. The flow of liquid emerging from the pipe so first hits the upper part of the impact surface, which is not perforated is, and only then flows past the air supply openings.
Zwei besonders vorteilhafte Ausführungsformen der Erfindung sind in den Fig. 1 und 2 dargestellt. Der Motor 1 treibt über eine Welle 2 den Rührer 3 an und fördert damit die Flüssigkeit in dem Rohr 4 in der Pfeilrichtung. Gemäß Fig. 1 wird die Luft durch Rohre 5 dem kegelförmigen Prallblech 6 zugeführt, das mit öffnungen 7 derart ausgerüstet ist, daß beim Vorbeiströmen der Flüssigkeit ein Venturieffekt auftritt Diese Ausführungsform ist immer dann vorteilhaft, wenn in ein bereits vorhandenes Gefäß ein Gaszerteiler eingehängt werden soll und, z. B. sur Reinigung, eine schnelle Entfernung des Gaszerteilers aus der Flüssigkeit erwünscht ist. In Fig. 2 ist eine ortsfeste Anlage dargestellt, bei der das kegelförmige Prallblech 6 mit Luftzufuhröffnungen 7 am Behälterboden vorgesehen ist. Die Luft wird durch die Hauptleitung 5, die sich in zvei oder mehr Äste teilt, der Flüssigkeit zugeführt. Two particularly advantageous embodiments of the invention are shown in Figs. The motor 1 drives the stirrer via a shaft 2 3 and thus promotes the liquid in the tube 4 in the direction of the arrow. According to Fig. 1, the air is fed through tubes 5 to the conical baffle 6, which is equipped with openings 7 in such a way that when the liquid flows past Venturi effect occurs This embodiment is always advantageous when in an already existing vessel a gas divider is to be hung and, for. B. sur cleaning, a quick removal of the gas splitter from the liquid is desirable is. In Fig. 2, a stationary system is shown in which the conical baffle 6 is provided with air supply openings 7 on the container bottom. The air gets through the main line 5, which divides into two or more branches, supplied to the liquid.
Gaszerteiler mit einer in einem lotrechten Leitrohr angeordneten Förderschraube. die die Flüssigkeit gegen ein kegelförmiges Prallblech fördert, das mit Öffnungen für die Gas zufuhr versehen ist, sind zwar schon bekannt. Gas splitter with one arranged in a vertical guide tube Conveyor screw. which conveys the liquid against a conical baffle plate, which is provided with openings for the gas supply are already known.
Bei diesen bekannten Anordnungen treten aber die in der Einleitung beschriebenen Nachteile auf, die erst dadurch vermieden werden, daß gemäß der Erfindung die offnungen in dem kegelförmigen Prallblecht außerhalb der lotrechten Projektion des die Förderschraube 3 umgebenden Rohres 5 auf das Prallblech angeordnet sind.In the case of these known arrangements, however, those appearing in the introduction described disadvantages, which can only be avoided that according to the invention the openings in the conical baffle outside the perpendicular projection of the pipe 5 surrounding the conveyor screw 3 are arranged on the baffle plate.
