Description

Verfahren zum Durchmischen oder Durchperlen von Gasen oder Dämpfen durch geschichtete pulverförmige Stoffe Die Erfindung bezieht sich auf ein Verfahren zum Durchmischen von Gasen oder Dämpfen mit geschichteten pulverförmigen Materialien zwecks Ausführung von chemischen oder physikalischen Prozessen.Process for mixing or bubbling gases or vapors by layered powdery substances The invention relates to a method for mixing gases or vapors with layered powdery materials for the purpose of performing chemical or physical processes.

Es ist bereits versucht worden, Gase oder Dämpfe auf pulverige Stoffe in der Weise physikalisch oder chemisch einwirken zu lassen, daß man die Stoffe mittels eines Rührwerkes verrührt und unter gleichzeitiger Einwirkung von durchströmenden Gasen oder Dämpfen auflockerte. Das neue Kennzeichen der vorliegenden Erfindung besteht hingeben darin, daß man für die Auflockerung der pulverigen 1Ias'se, wie sie durch das Hindurchströmen von Gasen oder Dämpfen erfolgt, einen Mischraum benutzt, der abwechselnd verengten und erweiterten Durchlaßquerschnitt besitzt. Die Dämpfe oder Gase «-erden dabei so durch diesen Mischraum hindurchgeleitet, daß sie durch das geschichtete Material sozusagen wie Luft durch eine Flüssigkeit hindurchperlen.Attempts have already been made to apply gases or vapors to powdery substances to act physically or chemically in such a way that the substances are allowed to act stirred by means of an agitator and with the simultaneous action of flowing through Gases or vapors. The new feature of the present invention consists in indulging in the need for loosening the powdery 1Ias'se, like it takes place through the flow of gases or vapors, uses a mixing room, the alternately narrowed and widened passage cross-section. The fumes or gases «earths passed through this mixing space in such a way that they pass through bubbling the layered material through a liquid, so to speak, like air.

In der Abbildung ist ein derartiger Dlischraum dargestellt; er besteht im wesentlichen in einer in beliebiger Lage aufwärts gerichteten Rühre mit abwechselnd verengten und erweiterten Durchlaßquerschnitten. Werden beispielsweise die unteren Kammern a, ai usw. einer derartigen Röhre mit dem pulverförmigen Stoff c gefüllt und läßt man von unten her einen Gas- oder Luftstrom in die Röhre eindringen, dann perlen oder glucksen Teilchen der Gase oder Dämpfe, wie es in der Abbildung dargestellt ist, durch die pulverige lIasse hindurch, letztere verteilt sich auf die darüberliegenden Kammern 2. 3 usw., indem sie jeweils an den verengten Stellen Schichten bildet, die von den nach oben aufströmenden Gasen oder Dämpfen ständig durchdrungen werden.Such a Dlischraum is shown in the figure; he exists essentially in a stirrer directed upwards in any position with alternating narrowed and widened passage cross-sections. For example, the lower ones Chambers a, ai, etc. of such a tube are filled with the powdery substance c and if a gas or air stream is allowed to enter the tube from below, then Particles of gases or vapors pearl or gurgle, as shown in the picture is, through the powdery passage, the latter is distributed to the one above Chambers 2, 3, etc., by forming layers at the narrowed points, which are constantly penetrated by the gases or vapors flowing upwards.

Während die mit Rührwerk versehenen Apparate sehr umständlich zu handhaben und auch schwer dicht zu halten sind, andererseits die Rührwerke auch einen erheblichen Teil des Innenraumes beanspruchen und dazu noch tote Räume bilden, ergibt sich bei der beanspruchten Einrichtung bei voller Ausnutzung des Innenraumes lediglich nur durch die Einwirkung der durchströmenden Gase und Dämpfe eine bisher unerreichte Mischung. lIan hat es hier=bei ohne weiteres in der Hand, die Gase oder Dämpfe unter beliebiger Verweilzeit unter den Pulverteilchen hindurchzuleiten, so daß sowohl physikalische gis auch chemische Prozesse in höchst -wirksamer ZVeise durchgeführt werden können.While the apparatus provided with a stirrer is very cumbersome to handle and are also difficult to keep tight, on the other hand the agitators also have a significant impact Claiming part of the interior space and also creating dead spaces results in the claimed facility with full utilization of the interior only due to the effects of the gases and vapors flowing through it, an unprecedented level Mixture. lIan has it here = at hand, the gases or vapors underneath to pass any dwell time under the powder particles, so that both physical gis also chemical processes carried out in a highly effective way can be.

Die Einrichtung, wie sie in der Abbildung dargestellt ist, kann eine beliebige Anzahl von erweiterten und verengten Querschnitten besitzen, sie kann beliebig hoch sein und je nach der Zweckv envendung in entsprechenden anderen Apparaturen angeordnet werden. Was die Gestaltung der Rohre anbelangt, so kommt es natürlich im wesentlichen nur auf die inneren Querschnittsveränderungen an, so daß die Apparatur im übrigen beliebige äußere Gestaltung haben kann.The device as shown in the figure can be a any number of widened and narrowed cross-sections own, it can be of any size and, depending on the intended use, in corresponding others Apparatus are arranged. As for the design of the tubes, so come of course, it essentially only depends on the changes in the internal cross-section, so that the apparatus can otherwise have any external design.

als physikalische oder chemische Prozesse kommen in Betracht z. B. die Absorption oder Trennung von Gasen und Dämpfen oder Dampfgemischen von festen pulverigen Stoffen, ferner Reaktionen. wie sie bei der Aktivierüng oder Reaktivierung kohlenstoffhaltiger Substanzen, ferner aktivierter Kieselsäure usw. vorgenommen werden, die gegebenenfalls auch mit einer Veränderung der festen pulverigen Substanz verbunden sein können.as physical or chemical processes come into consideration z. B. the absorption or separation of gases and vapors or vapor mixtures from solids powdery substances, furthermore reactions. as in the case of activation or reactivation carbon-containing substances, also activated silica, etc. made be that possibly also with a change in the solid powdery substance can be connected.

Selbstredend kann das Verfahren auch dazu benutzt -werden', katalytische Prozesse durchzuführen, bei welchen die pulverige Substanz eine aktivierte oder aktivierende sein kann. um chemische Veränderungen oder Umsetzungen zu bewirken.Of course, the process can also be used for catalytic purposes Perform processes in which the powdery substance is an activated or can be activating. to cause chemical changes or conversions.

So kann beispielsweise mittels eines Katalysators, den man dadurch herstellt, daß man Nickelhydrat mit Tonerdehydrat durch Soda ausfällte. danach wusch, reduzierte und fein pulverisierte, oder daß man eine 1Lischung von Natron-Wasserglas-Lösung und atriumaluminat durch eine Mischung von Nickelnitratlösung und Salpetersäure koagulierte, ebenfalls auswusch, trocknete, reduzierte und pulverte, danach fein gesiebt über die gasdurchlässige Wand o. dgl. brachte und unter Erhitzung auf 25o° ein Gasgemisch von Kohlenoxyd und überschüssigem Wasserstoff hindurchleitete, Methan gewonnen werden. 31s Beweis für die innige -Mischung ist hervorzuheben, daß bei Versuchen dieser Art in der Regel keine Spur von hohl: noxyd nachzuweisen ist.So, for example, by means of a catalyst, which one thereby produces that one precipitated nickel hydrate with alumina hydrate by soda. afterwards washed, reduced and finely pulverized, or a mixture of soda-waterglass solution and atrium aluminate by a mixture of nickel nitrate solution and nitric acid coagulated, also washed out, dried, reduced and powdered, then fine sifted over the gas-permeable wall or the like and brought with heating to 25o ° a gas mixture of carbon monoxide and excess hydrogen passed through, methane be won. 31s proof of the intimate mixture is to be emphasized that with Attempts of this kind as a rule do not show any trace of hollow: noxyd.

Eine in den Apparat gebrachte, fein gepulverte aktive Kieselsäure ergab, nachdem in der beschriebenen --"eise ein acetonhaltiger Luftstrom hindurchgeschickt war, Restgase, die praktisch frei waren von Aceton.A finely powdered active silica placed in the apparatus revealed after a stream of air containing acetone was sent through in the described - "ice was, residual gases that were practically free of acetone.

In derselben Weise lassen sich auch Reaktionen ausführen, die mit einem Verbrauch der festen Stoffe verbunden sind, wie z. B. die Wassergasbildung aus Kohlenstaub und Wasserdampf oder die Aktivierung oder Reaktivierung von kohlenstoffhaltigen Substanzen, ferner die Wiedergerinnung von durch Absorptionsstoffe aufgenommenen Gasen oder Dämpfen, ebenso aber auch die Regenerierung von Katalysatoren usw.In the same way, reactions can also be carried out with a consumption of solid substances are associated, such as. B. the formation of water gas from coal dust and water vapor or the activation or reactivation of carbonaceous Substances, as well as the coagulation of those absorbed by absorption substances Gases or vapors, but also the regeneration of catalysts, etc.
