Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mit der mit einfachen und räumlich kleinbauenden Mitteln ein wirksames Vermischen und Reagieren eines Gases und/oder einer Flüssigkeit mit einem flüssigen Medium erreicht werden kann.The invention has for its object to provide a device with which with simple and physically small-scale means an effective mixing and reacting a gas and / or a liquid can be achieved with a liquid medium.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is solved by the features of patent claim 1.
Bei der erfindungsgemäßen Vorrichtung ist ein aufrechter Behälter, beispielsweise in Zylinderform, vorgesehen, mit einem unteren Zulauf für das flüssige Medium und mindestens einem oberen Ablauf. Das flüssige Medium kann z. B. gereinigtes Abwasser sein oder Wasser, das von schädlichen oder unerwünschten Substanzen, wie z. B. Phosphaten, weitgehend befreit ist. Der Zulauf ist mit mindestens einem Injektionsanschluß versehen, über den Gas und/oder Flüssigkeit, z. B. über ein Kegelventil, in das zuströmende flüssige Medium eingegeben werden kann, z. B. zu Entkeimungszwecken. Das Gas oder die Flüssigkeit enthält z. B. eine Substanz, mit der Keime in dem flüssigen Medium durch Reaktion oder auf andere Weise abgetötet werden können.In the apparatus according to the invention, an upright container, for example in the form of a cylinder, is provided, with a lower inlet for the liquid medium and at least one upper outlet. The liquid medium may, for. As purified waste water or water, the harmful or undesirable substances, such as. As phosphates, is largely exempt. The inlet is provided with at least one injection port, via the gas and / or liquid, for. B. via a cone valve, can be entered into the inflowing liquid medium, z. B. for sterilization purposes. The gas or liquid contains z. B. a substance with which germs in the liquid medium can be killed by reaction or otherwise.
An den Zulauf schließt sich eine Mischkammer an, die auch eine ruhige Mischzone bildet und die in ihrer Größe an die jeweils erforderlichen Reaktionszeiten angepaßt werden kann. Oberhalb der Mischkammer befinden sich statische Mischelemente, mit welchen eine intensive Vermischung des Gases und/oder der Flüssigkeit mit dem flüssigen Medium sowie eine Verlangsamung der Strömungsgeschwindigkeit erfolgt. Oberhalb der statischen Mischelemente ist in einer zweiten Mischkammer ein Rührwerk vorgesehen. Über die Mischelemente wird die Strömung verlangsamt bzw. aufgestaut, wodurch sich die Reaktionszeit verlängert und außerdem eine weitere intensive Vermischung der injizierten Flüssigkeit bzw. des injizierten Gases mit dem flüssigen Medium erfolgen kann.At the inlet is followed by a mixing chamber, which also forms a quiet mixing zone and which can be adapted in size to the respective required reaction times. Above the mixing chamber are static mixing elements, with which there is an intensive mixing of the gas and / or the liquid with the liquid medium and a slowing down of the flow velocity. Above the static mixing elements, a stirrer is provided in a second mixing chamber. About the mixing elements, the flow is slowed or dammed, which extends the reaction time and also can be carried out a further intensive mixing of the injected liquid or the injected gas with the liquid medium.
Abhängig von der erforderlichen Prozeß- und Reaktionszeit kann die Menge der Dosierung von Gas und/oder Flüssigkeit stufenlos geregelt und bei Bedarf auch komplett abgestellt werden. Die erfindungsgemäße Vorrichtung erlaubt die Vermischung von Medien über eine größtmögliche Phasengrenzfläche.Depending on the required process and reaction time, the amount of metering of gas and / or liquid can be regulated steplessly and completely switched off, if necessary. The device according to the invention allows the mixing of media over the largest possible phase interface.
Bei der Erfindung sind die statischen Mischelemente so ausgebildet, dass die Strömung im Behälter in einer ersten Drehrichtung stattfindet und der Rotor des Rührwerks in entgegengesetzter Richtung dreht. Vorzugsweise werden die statischen Mischelemente von mehreren übereinander im Abstand angeordneten Lochplatten gebildet, die in begrenzten Sektoren eine Lochanordnung aufweisen, wobei die Lochsektoren jeweils in einem Winkel gegenüber den Lochsektoren der benachbarten Platten angeordnet sind. Beim Durchströmen der im Winkel versetzten Lochanordnungen der Lochplatten wird der Strömung ein Drall erteilt, der dem Drall, der vom Rührwerk erzeugt wird, entgegengesetzt gerichtet ist. Auf diese Weise wird die Vermischung intensiviert. Außerdem wird mit Hilfe der Lochplatten ein längeres Verweilen der Medien im Behälter erzielt.In the invention, the static mixing elements are designed so that the flow takes place in the container in a first direction of rotation and rotates the rotor of the agitator in the opposite direction. Preferably, the static mixing elements are formed by a plurality of spaced-apart perforated plates which have a hole arrangement in limited sectors, wherein the perforated sectors are each arranged at an angle to the hole sectors of the adjacent plates. As it flows through the angularly offset hole arrangements of the perforated plates, a swirl is imparted to the flow which is directed opposite to the swirl produced by the agitator. In this way the mixing is intensified. In addition, a longer retention of the media in the container is achieved by means of the perforated plates.
Die erfindungsgemäße Vorrichtung ist insbesondere geeignet zum Entkeimen von geklärten Abwässern oder von gereinigtem Wasser, das seinem Ursprungszweck wieder zugeführt werden soll, beispielsweise gereinigtes Wasser in ein Gewässer oder dergleichen. Die Erfindung wird nachfolgend anhand eines in einer Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The device according to the invention is particularly suitable for the sterilization of clarified effluents or of purified water which is to be returned to its original purpose, for example purified water into a body of water or the like. The invention will be explained in more detail with reference to an embodiment shown in a drawing.
