"Vorrichtung zur Mischung von Flüssigkeiten und Gasen mittels Ringsprung der Flüssigkeitsströmung""Device for mixing liquids and gases by means of the ring jump of the liquid flow "
Diese Erfindung betrifft die Mischung von Flüssigkeiten während technologischer Prozesse, bei der Wasseraufbereitung und Wasserreinigung, z. B. bei der Mischung von flüssigen und gasförmigen Flüssigkeiten, bei der Desinfektion und Sterilisation von Wasser mittels Ozon und Chlor, zur Wasserentgasung und Ausscheidung von unerwünschten Verbindungen im Wasser, bei der biologischen und chemischen Reinigung von Abwässern, bei der Schlammeindickung, Flotation usw.This invention relates to the mixing of liquids during technological processes, in water treatment and water purification, z. B. when mixing liquid and gaseous liquids, when disinfecting and sterilizing water by means of ozone and chlorine, for water degassing and the elimination of undesired compounds in water, in biological and chemical cleaning of wastewater, sludge thickening, flotation, etc.
Es ist bekannt, zur Durchgasung von Flüssigkeiten in der technischen Praxis verschiedene Verfahren, wie Berieselung, Zerspritzung, Aufwirbelung des Wasserspiegels, Mischung mittels mechanischer Rührer, Durchperlung, Ansaugung durch EJektionsauswirkung, Eintreibung von Gas in Flüssigkeiten mittels Gebläsen und Kompressoren anzuwenden. Diese Verfahren sind meistenteils wenigIt is known for the gas penetration of liquids in the technical Practice various methods such as sprinkling, spraying, whirling up the water level, mixing by means of mechanical Stirrer, bubbling, suction by ejection effect, drive-in of gas in liquids by means of fans and compressors. For the most part, these procedures are few

wirkungsvoll, weisen viele Nachteile im Betrieb und großen Energieverbrauch auf, wobei die Mischvorrichtung einen großen Raum in Anspruch nimmt. Grundsätzlich wirkungsvoller ist die Mischung, welche die Übergangserscheinungen der Strömung, den Wassersprung in der Rohrleitung und den Ringsprung benützt.effective, have many disadvantages in operation and high energy consumption and the mixing device occupies a large space. The mixture is basically more effective which uses the transition phenomena of the flow, the water jump in the pipeline and the ring jump.
Der Erfindung liegt die Aufgabe zugrunde, die Nachteile der bisher bekannten Vorrichtungen zur Mischung von Flüssigkeiten und Gasen auszuschalten und eine wirkungsvoller billigere und raumsparende Vorrichtung zu schaffen.The invention is based on the disadvantages of the previous turn off known devices for mixing liquids and gases and a more effective cheaper and space-saving To create device.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein sehr hoher Mischungseffekt mit minimalem Energieverbrauch mittels Ringsprung der Flüssigkeitsströmung dadurch erreicht wird, daß deren Hauptteil aus einer Mischrohrleitung besteht, welche beim Einlauf mit einer kreisförmigen, koaxial in der Mischrohrleitung angebrachten Profilplatten versehen ist. Sie weist einen Durchmesser auf, d^ der kleiner als der Innendurchmesser der Mischrohrleitung d. zur Bildung der Ringströmung der Flüssigkeitskomponente ist, und zwar so, daß d^/di =0,75 bis 0,98 ist, wobei die Rohrleitung eine Öffnung zum Zuführen einer weiteren Flüssigkeitskomponente (Gase) in den hohlen Kern der Ringströmung in der Mischrohrleitung vor dem Übergang der Ringströmung in die Strömung durch das ganze Profil aufweist«, Die Übergangserscheinung zwischen den beiden Strömungstypen - der Ringsprung treibt Gas (oder Flüssigkeiten) aus dem hohlen Kern der Ringströmung in die Druckströmung durch das ganze Profil, wobei alle Komponenten in turbulenten Wirbeln perfekt in eine homogene Emulsion vermischt werden,, Das Eintreibvermögen des Rlngsprungs ist beträchtlich, bei einer teilweise« Sättigung dss $tr$mungsk®rn©s ©rschaintThis object is achieved according to the invention in that a very high Mixing effect with minimal energy consumption by means of the ring jump of the liquid flow is achieved in that its main part consists of a mixing pipe which, at the inlet, is connected to a circular profile plate that is coaxially attached to the mixing pipe is provided. It has a diameter that is smaller as the inside diameter of the mixing pipeline d. to form the annular flow of the liquid component, in such a way that d ^ / di = 0.75 to 0.98, the pipeline having an opening for feeding another liquid component (gases) into the hollow core of the annular flow in the mixing pipeline before the transition of the Having annular flow in the flow through the entire profile «, The Transition phenomenon between the two types of flow - the ring jump drives gas (or liquids) out of the hollow core of the ring flow in the pressure flow through the entire profile, with all components in turbulent eddies perfectly in a homogeneous emulsion be mixed, the driving power of the jump is considerable, with a partial "saturation"

hier ein Unterdruck, welcher zum Ansaugen der zusätzlichen Flüssigkeitskomponente ausgenützt werden kann« Die Entstehung des Ringsprunges ist durch die Gleichheit der Druckkraft hinter dem Sprung mit der dynamischen Kraft des Ringsprungs bedingt.here a negative pressure, which is used to suck in the additional liquid component can be exploited «The formation of the ring jump is due to the equality of the pressure force behind the jump with the dynamic force of the ring jump.
Die Mischvorrichtung ist räumlich nicht anspruchsvoll; grundsätzlich handelt es sich um die Anwendung eines zur Bildung der Ringströmung nötigen Konstruktionselementes in der Rohrleitung. Es ist vorteilhaft, daß die agressiven Gase oder agressiven chemischen Stoffe, die in den Kern der Ringströmung zugeführt werden, mit dem Material der Mischrohrleitung ersit mit dei Flüssigkeit vermischt, also in einem sehr verdünnten Zustand, in Berührung kommen.The mixing device is not spatially demanding; basically it involves the use of a construction element in the pipeline that is necessary for the formation of the annular flow. It is advantageous that the aggressive gases or aggressive chemical Substances that are fed into the core of the annular flow are mixed with the material of the mixing pipeline instead of with the liquid, so in a very dilute state, come into contact.
Die Vorrichtung kann bei der Aufbereitung von Trinkwasser, d. h. bei der Ozonisierung, Chlorierung, Belüftung, Entmanganung, Enteisenung, Dekarbonisation etc., bei der Reinigung von Abwässern, bei technologischen Prozessen insbesonders in der chemischen Industrie, Papier-, Zellulose-, Pharmazeutischen-Industrie, bei der Raffination von Mineralölen etc, verwendet werden.The device can be used in the treatment of drinking water, i. H. in ozonation, chlorination, ventilation, manganese removal, iron removal, Decarbonization, etc., when cleaning wastewater, in technological processes, especially in the chemical industry, Paper, cellulose, pharmaceuticals industries Refining of mineral oils etc, can be used.
