Verfahren zur Regenerierung von künstlichen Zeolithen.Process for the regeneration of artificial zeolites.
Patentiert im Deutschen Reiche vom 13. April 1911 ab.Patented in the German Empire on April 13, 1911.
Es ist bekannt, daß künstliche Natriumzeolithe, welche zur Enthärtung von Wässern Verwendung finden, sobald sie ihr ganzes Natrium gegen Calcium und Magnesium aus den Salzen des Wassers umgetauscht haben, dadurch regeneriert werden, daß man eine Lösung von Kochsalz über die Zeolithschicht bringt und in ruhigem Strome bei einer unten am Filter angeordneten regelbaren. ÖffnungIt is known that artificial sodium zeolites, which are used to soften water as soon as they have all their sodium have exchanged for calcium and magnesium from the salts of the water, be regenerated by placing a solution of common salt over the zeolite layer brings and in a calm stream with a controllable one arranged at the bottom of the filter. opening
ίο durch mehrere Stunden hindurch auslaufen läßt. Hierbei wird wieder das Natrium des Kochsalzes gegen das im Zeolith enthaltene Calcium und Magnesium umgetauscht; dieses Spiel läßt sich beliebig oft wiederholen. Bei dieser Art der Regenerierung verbraucht man, wie sich gezeigt hat, mehr als das Vierfache der theoretisch nötigen Salzmenge.ίο run out for several hours leaves. Here, the sodium in the table salt is again set against that in the zeolite Calcium and magnesium exchanged; this game can be repeated as often as you like. at As has been shown, this type of regeneration consumes more than four times as much the theoretically required amount of salt.
Zweck vorliegender Erfindung ist nun, den Verbrauch an Kochsalz durch dessen bessere Ausnutzung zu verringern, was dadurch erreicht wird, daß man die Kochsalzlösung nicht in ruhigem Strom durch die Zeolithe fließen läßt, sondern hierbei in steter Auf- und Abbewegung erhält, wodurch eine innigere Berührung zwischen Salz und Zeolith und damit die angestrebte günstigere Austauschwirkung erzielt wird. Dies kann nun dadurch erreicht werden, daß man die Salzlösung während des Ablaufens bei einer unten angebrachten regelbaren Öffnung zeitweise oder während der ganzen Regenerierzeit in . eine Auf- und Abwärtsbewegung bringt, z. B. dadurch, daß in einem neben dem Filter befindlichen ' und mit diesem kommunizierenden Gefäß ein Kolben auf und ab geführt wird, durch dessen wechselnde Flüssigkeitsverdrängung die gewünschte Auf- und Abbewegung der Salzlösung im Filter selbst erzielt wird.The purpose of the present invention is now to reduce the consumption of table salt by improving it To reduce utilization, which is achieved by not having the saline solution can flow in a steady stream through the zeolites, but here in constant up and down movement receives, whereby a closer contact between salt and zeolite and thus the desired more favorable exchange effect is achieved. This can now be achieved by keeping the saline solution during the drainage at a lower adjustable opening temporarily or during the entire regeneration time in. brings an up and down movement, e.g. B. in that in a vessel located next to the filter and communicating with it, a piston is guided up and down, through the changing fluid displacement of which the desired Up and down movement of the saline solution in the filter itself is achieved.
