Der der vorliegenden Erfindung zugrunde liegende Gedanke. besteht darin, daß die überführung des zur Anwendung gelangenden pulverförmügen Stoffes in den flüssigkeitsähnlichen ' Zustand in verhältnismäßig dünner. Schicht in einem Adsorptionsraum auf unterer;:nander angeordneten . waagerechten Lochböden erfolgt und der pulverförmige Stoff nach beendeter Adsorption vermittels einer-' Transportvorrichtung in einen zweiten in gleicher Weise ausgestatteten Desorptionsraum geführt wind und im Kreislauf wleder dem ersten Adsorptionsraum zufließt. Dabei ist der Querschnitt des Gasdurchganges in den siebartigen Böden je'nach der Korngröße und dem Raumgewicht der pulverförmigen Stoffe derartig zu gestalten, daß die Aufwirbe-Iung über dem ganzen über den siebartigen .-''Böden vorhandenen freien Querschnitt erfolgt.The idea on which the present invention is based. consists in that the overpass of the powder form used Substance in the liquid-like 'state in relatively thinner. layer in an adsorption space on the lower;: nander arranged. horizontal perforated shelves takes place and the powdery substance after the end of adsorption by means of a- ' Transport device into a second desorption room equipped in the same way guided wind and in the circuit that flows into the first adsorption chamber. Included is the cross-section of the gas passage in the sieve-like bottoms depending on the grain size and to shape the density of the powdery substances in such a way that the whirling-up takes place over the entire free cross-section existing over the sieve-like - '' bottoms.
Bei Benutzung des Verfahrens zur Adsorption von Eohlenwasserstoffen
aus Gasen vermittels Aktivkohle ergeben sich z. B. folgende Abhängigkeiten
Nach stattgefundener Adsorptian kann das pulverförn-dge Gut in bekannter Weise, z. B. pneumatisch. oder mittels Transporteiniichtungen, wie Schnecken einer Drsorptionsvorrichtung zugeführt werden. Die Desorption kann hierin in ähnlicher Weise wie die Adsorption durchgeführt werden. Das Gut gelangt nach der Desorption wiederuni in dien Adsbrptionsraum zurück, wodurch der Kreislauf geschlossen ist.After adsorption has taken place, the powdery material can be used in known Way, e.g. B. pneumatic. or by means of transport devices, such as screws Drsorptionsvorrichtung are supplied. The desorption can be carried out in a similar manner herein Way how adsorption can be carried out. The goods arrive after desorption again in the adsorption space, whereby the cycle is closed.

In dein Behälter i, in welchem .die Adsörption durchgeführt werden soll, sind die Siebböden a übereinander in gewissem Abstand angeordnet. Diese Siebböden erstrecken sich nicht über den ganzen Querschnitt, sondern lassen seinen überlaufraum 3 frei, dessen Wandung 4. im gewissen Abstand von dem nächst darunterbefindlichen Sieb endet. Das der Ads.orption zu unterwerfende Gut gelangt durch den Fülltrichter 5 auf den obersten Siebboden 2. Dabei ist bei. Inbetriebnalune der Apparatur dafür Sorge zu tragen, daß die freien überlaufräume 3 nacheinander von oben nach unten mit dem Gut durch die dafür vorgesehenen Stutzen 6 beschickt werden, damit das unten üi den.Adsorptionsbehälter durch den Stutzen 7 eingeleitete Gas gezwungen, ist, durch die Löcher der Siebböden durchzutreten und nicht durch die freienüberlaufräume 3. Der Gasaustritt ist mit S bezeichnet. Der durch die Siebböden tretende Gasstrom bewirkt ein sofortiges horizontales Einstellen der auf den Siebböden befindlichen Schichten des pulverförmigen Stoffes, der dabei, wie bekannt, iti -;einen flüssigkeitsähnlichen, 'leicht fließbaren Zustand versetzt wird. Dieser Zustand bewirkt, daß die pulverförmige Masse je nach der am unteren Siebboden abgezogenen Menge sich in horizontaler Richtung auf den einzelnen Böden bewegt, wobei die Schichthöhe nach oben durch den Abstand der unteren Kante der Trennwand q vom darunterbefindliehen Boden begrenzt ist. Das am unteren Siebboden bei. 9 abgezogene Gut gelangt durch eine Transportvorrichtung, z. B. eine Schnecke i o, in den oberhalb des Adsorptionsraumes ' angeordneten Desorptionsbehälter i i. In diesem Behälter sind in genau der gleichen Weise,- wie dies ,beim Adsorptionsbehälter geschehen ist, siebattig gestaltete Böden 2, die im vorliegend gezeichneten Ausführungsbeispiel kleinere Ausmaße aufweisen; angeordnet, die ebenfalls überlaufräume 3 und diese begrenzende Wandungen q. aufweisen. Auch hierbei sind Füllstutzen 6 vorgesehen, um bei Inbetriebnahme das Gas zu zwingen, durch die Löcher des Siebbodens zu streichen.- Das zur Desorption- zur Verwendung kommende Gas strömt in den Behälter bei i2 ein und tritt bei 13 aus. Das durch den Desorptionsbehälter i i wandernde Gut gelangt über den Ausfallstutzen i¢ wieder auf den ersten Siebboden des Adsorptionsbehälters i.In your container i, in which the adsorption are carried out should, the sieve trays a are arranged one above the other at a certain distance. These sieve trays do not extend over the entire cross-section, but leave its overflow space 3 free, its wall 4. at a certain distance from the next one below it Sieve ends. The material to be subjected to adsorption passes through the filling funnel 5 on the uppermost sieve tray 2. It is at. Commissioning of the equipment for this To ensure that the free overflow spaces 3 one after the other from top to bottom can be charged with the goods through the nozzles 6 provided for this purpose, so that the bottom üi den.Adsorptionsbehälter is forced through the nozzle 7 introduced gas, to pass through the holes in the sieve trays and not through the free overflow spaces 3. The gas outlet is labeled S. The gas flow passing through the sieve trays causes an immediate horizontal adjustment of those on the sieve bottoms Layers of the powdery substance, which, as is known, iti -; a liquid-like, 'easily flowable state is added. This condition causes the powdery Depending on the amount drawn off at the lower sieve bottom, the mass moves horizontally Moved on the individual floors, the layer height upwards through the distance the lower edge of the partition q is bounded by the floor below. That at the bottom of the sieve. 9 withdrawn goods pass through a transport device, z. B. a screw i o, in the above the adsorption 'arranged desorption container i i. In this container are in exactly the same way - as this in the adsorption container has happened, Siebattig designed floors 2, which in the presently drawn embodiment have smaller dimensions; arranged, the also overflow spaces 3 and this delimiting walls q. exhibit. Here, too, filler nozzles 6 are provided, in order to force the gas to pass through the holes in the sieve bottom when starting up. The gas used for desorption flows into the container at i2 and exits at 13. The material migrating through the desorption container i i arrives via the outlet nozzle i ¢ back to the first sieve bottom of the adsorption container i.
