Description

Einrichtung zur Auslösung eines chemischen Vorgangs in einer Flüssigkeit durch ein Gas unter Zuhilfenahme eines Mischgasflüssigkeithebers (Rlammut-PLimpe).Device for triggering a chemical process in a liquid by a gas with the help of a mixed gas liquid lifter (Rlammut-PLimpe).

Für die Auslösung eines chemischen Vorgangs in einer Flüssigkeit durch ein Gas eignen sich im besonderen Maße Mischgasflüssigkeitsheber, sogenannte » Mammut-Pumpein«. For triggering a chemical process in a liquid mixed gas liquid lifters, so-called "Mammoth Pump".

Die Wirkungsweise der sogenannten Mammut-Pumpen beruht, wie bekannt, darauf, daß aus Flüssigkeit und eingeführtem Gas eine Emulsion gebildet wird, die infolge ihres spezifisch leichteren Gewichtes im Förderrohr hochsteigt. Verwendet man nun zum Betrieb einer derartigen Mammut-Pumpe das betreffende Gas, das auf die Flüssigkeit chemisch einwirken soll, so zeitigt die Verwendung der Mammut-Pumpe den doppelten Vorteil daß einerseits Gas und Flüssigkeit innigst miteinander in Berührung gebracht wird, anderseits der gesamte Inhalt des Behälters eine gründliche Durchrührung erfährt. The mode of operation of the so-called Mammut pumps is based, as is known, that an emulsion is formed from the liquid and the gas introduced, which due to their specifically lighter weight rises in the delivery pipe. Used you now to operate such a mammoth pump, the gas in question, which is on the If the liquid is to have a chemical effect, the use of the Mammut pump is the starting point the double advantage that on the one hand gas and liquid are intimately intertwined Contact is brought, on the other hand, the entire contents of the container a thorough Experienced agitation.

Soweit nun Gase verwendet werden, die Metalle nicht angreifen, hat man, wie allgemein bei Mammut-Pumpen üblich, das Gas auf den zum Betrieb der Einrichtung notwen'digen Druck mit Hilfe von Kompressoren o. dgl. komprimiert. As far as gases are used that do not attack metals as is generally the case with Mammut pumps, the gas on the to Operation of the device necessary pressure with the help of compressors or the like. Compressed.

Handelt es sich aber um Gase, die die Metalle angreifen, beispielsweise Chlorgas, so war bisher die Verwendung der Mammut-Pumpen im Rahmen der Durchführung eines chemischen Vorgangs, bei dem eine Flüssigkeit mit einem Gas innigst in Berührung gebracht werden mußte, ausgeschlossen. But if it is a question of gases that attack the metals, for example Chlorine gas, this is how Mammut pumps were used in the implementation a chemical process in which a liquid comes into intimate contact with a gas had to be brought, impossible.

Die Herstellung beispielsweise von Calcium-Chlorat, wobei Chlorgas in Kalkmilch geleitet und unter Bindung des Chlorgases Chlorat erzeugt wird, mußte daher auf andere Weise erfolgen, indem man durch mechanische Rührwerke oder Rieseltürme das Gas mit der Flüssigkeit in Berührung brachte. The production, for example, of calcium chlorate, taking chlorine gas led into milk of lime and chlorate is produced by binding the chlorine gas, had to therefore done in a different way, by moving through mechanical agitators or trickle towers brought the gas into contact with the liquid.

Ausbeute sowohl als auch Wirtschaftlichkeit infolge erheblicher Zeitdauer waren daher sehr gering. Both yield and economy due to considerable length of time were therefore very low.

Der Zweck der Erfindung ist es nun, eine Einrichtung zu schaffen, die es ermöglicht, auch bei Verwendung von Gasen der bezeichneten Art die Mammut-Pumpe verwenden zu können, und zwar geschieht dies erfindungsgemäß dadurch, daß das zum Betrieb der Mammut-Pumpe benötigte Gas anstatt mit einem Kompressor mit Hilfe eines Strahlapparates auf den notwendigen Überdruck verdichtet wird. Ein derartiger Strahlapparat, der ohne Schwierigkeit aus säurebeständigem Material hergestellt werden kann, gibt die Möglichkeit, das betreffende Gas durch Preßluft, Dampf oder eine beliebige Druckflüssigkeit anzusaugen und so weit zu verdichten, wie es der Betrieb der Mammut-Pumpe verlangt. Bekanntermaßen genügt hierfür ein verhältnismäßig geringer Überdruck. Es wird infolgedessen bedeutend weniger Kraft verbraucht, als notwendig ist, um das Mischen des Gases mit der betreffenden Flüssigkeit, wie es auch bereits vorgeschlagen ist; ~ mit Hilfe von Mischdüsen zu bewirken, abgesehen davon, daß hierbei stets noch die Frage offen bleibt, wie das betreffende Gas auf den notwendigen Überdruck zur Inbetriebsetzung der Mischdüsen komprimiert wird. The purpose of the invention is now to create a device which makes it possible to use the Mammut pump even when gases of the specified type are used to be able to use, and this is done according to the invention in that the for Operation of the Mammut pump required gas instead of a compressor with the help of a Jet apparatus is compressed to the necessary overpressure. Such a jet machine, which can be made of acid-resistant material without difficulty the possibility of the gas in question by compressed air, steam or any pressure fluid suction and compress as much as the operation of the Mammut pump requires. As is known, a relatively low overpressure is sufficient for this. It will as a result Consumes significantly less power than is necessary to mix the gas with the liquid in question, as has already been suggested; ~ with help by mixing nozzles, apart from the fact that here the question is still open remains, like the gas in question, to the necessary overpressure for start-up the mixing nozzle is compressed.

Die Zeichnung veranschaulicht durch die Abb. I bis 4 drei Ausführungsbeispiele einer derartigen Einrichtung. The drawing illustrates three exemplary embodiments by means of FIGS such a facility.

Bei dem Ausführungsbeispiel nach Abb. I ist a ein Injektor aus säurebeständigem Material, dem durch das Rohr b ein beliebiges Druckmittel zugeführt wird, das durch das Rohr c das betreffende Gas ansaugt und verdichtet. Dieses wird durch das Rohr d dem Mischgasfiüssigkeitsheber, der aus dem Förderrohre und Saugstutzeng besteht, bei 1 zugeführt. Über dem Förderrohr kann in bekannter Weise eine Haubeh vorgesehen sein, um das Herausschleudern der Flüssigkeit aus dem Behälters zu verhindern. In the embodiment according to Fig. I, a is an injector made of acid-resistant Material to which any pressure medium is fed through the pipe b which is passed through the pipe c sucks in the gas in question and compresses it. This is through the pipe d the mixed gas liquid siphon, which consists of the delivery pipe and suction nozzle, fed at 1. A hood can be provided over the conveyor pipe in a known manner to prevent the liquid from being thrown out of the container.

Der Behälter kann aus Zweckmäßigkeitsgründen einen trichterförmigen Boden k bekommen, damit die ganze Flüssigkeit an der Bewegung teilnimmt und sich keine Ablagerungen bilden können. For convenience, the container can be funnel-shaped Get floor k so that all the liquid participates in the movement and becomes no deposits can form.

Um zu vermeiden, daß durch das Gas das die zusammengesetzten Rohre abdichtende Material zu stark angegriffen wird, empfiehlt sich ein Aufbau im Sinne des Ausführungsbeispiels nach Abb. 2, wobei das Rohr d achsial in das Förderrohr e einmündet, so daß keinerlei Dichtungen erforderlich sind. Man kann das Rohr d mit dem ganzen Injektoraufbau auch oberhalb der in Reaktion tretenden Flüssigkeit bzw. außerhalb des Behälters aufhängen bzw. stützen. In order to avoid that the assembled pipes through the gas If the sealing material is attacked too strongly, a structure in the sense is recommended of the embodiment according to Fig. 2, wherein the pipe d axially into the conveyor pipe e opens, so that no seals are required. One can use the pipe d with the whole injector structure also above the reacting liquid or hang or support outside of the container.

Die Haube h kann unmittelbar an dem Rohr d sitzen. Sollte der Weg vom unteren Ende des Rohres bis zum oberen Ende des Förderrohres vornehmlich für die Mischung und auch für die Reaktion nicht ausreichen, dann kann man diesen Weg dadurch verlängern, daß man im Förderrohr e und an dem Gasmischrohr d gegeneinander versetzte Widerstände m und n anordnet, so daß das Gemisch aus Gas und Flüssigkeit gezwungen ist, einen Zickzackweg zu beschreiben.The hood h can sit directly on the pipe d. Should be the way from the lower end of the pipe to the upper end of the conveyor pipe primarily for the mixture and also not sufficient for the reaction, then you can go this way by lengthening the fact that one in the delivery pipe e and on the gas mixing pipe d against each other staggered resistors m and n arranged so that the mixture of gas and liquid is forced to describe a zigzag path.

Läßt es sich aus baulichen oder anderen Gründen nicht einrichten, dem Gefäß einen konischen Boden und engen Querschnitt zu geben, dann kann man auch mehrere solcher Mischvorrichtungen im Sinne der Abb. 3 und 4, durch welche die Einrichtung im Schnitt und in der Oberansicht dargestellt ist anordnen und hierbei entweder jedes der Rohre d mit einem eigenen Injektor a und Gaszuführungsrohr c versehen, oder man baut die Teile a und c in das gemeinsame Zuführungsrohr r ein. Die Wirkung an sich bleibt für jede einzelne Mischvorrichtung wie bei der Abb. 2. If it cannot be set up for structural or other reasons, To give the vessel a conical bottom and narrow cross-section, then you can too several such mixing devices in the sense of Fig. 3 and 4, through which the device in section and shown in the top view is to arrange and here either each of the pipes d is provided with its own injector a and gas supply pipe c, or parts a and c are built into the common feed pipe r. The effect per se remains for each individual mixing device as in Fig. 2.
