Description
Verfahren zum Regenerieren von basenaustauschenden Stoffen.Process for the regeneration of base-exchanging substances.
Zusatz znm Patent 397848. Addendum to patent 397848.
Vorliegende Erfindung betrifft eine Verbesserung des durch das Hauptpatent 397 848 bekannt gewordenen Verfahrens zum Regenerieren basenaustauschender Stoffe und besteht im wesentlichen darin, daß die von einer vorhergehenden Regeneration wieder aufgefangene Salzlösung als solche nach Zusatz einer bestimmten Salzmenge zur Regeneration wiederverwendet wird. Zweckmäßig wird bei diesem Verfahren der stark kalkhaltige Teil der Salzlösung abgelassen, hierauf der weniger kalkhaltige Teil in einem Gefäß aufgefangen und durch Zugabe neuen Salzes auf die gewünschte Konzentration angereichert. The present invention relates to an improvement of the main patent 397 848 known method for regenerating base-exchanging substances and consists essentially in that of a previous regeneration recovered saline solution as such after adding a certain amount of salt is reused for regeneration. In this method, the The heavily calcareous part of the salt solution was drained, then the less calcareous part Part caught in a vessel and adjusted to the desired by adding new salt Enriched concentration.
Da bei dem Wiederauffangen der schon gebrauchten Salzlösung und des schwach salzhaltigen Auswaschwassers eine verhältnismäßig große Flüssigkeitsmenge von schwacher Salzkonzentration gewonnen wird, die immer noch einen gewissen Kalkgehalt enthält, so muß die Menge des neu zuzugebenden Kochsalzes derart sein, daß die in der Lösung befindliche Kalkmenge eine voll wirksame Regeneration nicht beeinträchtigt. Als mindest erforderliche Konzentration hat sich hierbei eine etwa 61!2prozentige Lösung erwiesen. Since when the saline solution and the weakly salty wash-out water a relatively large amount of liquid is obtained from weak salt concentration, which still has a certain lime content contains, the amount of salt to be added must be such that the in the amount of lime in the solution does not impair a fully effective regeneration. The minimum required concentration has proven to be about 61! 2 percent Proven solution.
Im übrigen kann der Regenerationsvorgang wie bisher vorgenommen werden, d. h. die Salzlösung wird oben auf das Material geleitet und nach Ablassen des am stärksten kalkhaltigen Teiles unterhalb des Filtermaterials der wiederzuverwendende Teil in das Salzlösegefäß eingeleitet, sei es durch Entleerung des Filters oder durch Verdrängung der Salzlösung mittels Wasser aus der Richtung von oben nach unten. Otherwise, the regeneration process can be carried out as before, d. H. the saline solution is directed onto the top of the material and after draining the am the strongest calcareous part below the filter material that is to be reused Part introduced into the salt dissolving vessel, be it by emptying the filter or by displacing the saline solution with water from the direction from top to bottom.
Die bei der Auswaschung im Porenvolumen noch verbleibende, nur schwach kochsalzhaltige Lösung kann ebenfalls in das Salzlösegefäß geleitet werden. Dieser so gewonnenen Flüssigkeitsmenge wird nun eine bestimmte Menge Kochsalz zugesetzt, so daß der Kochsalzgehalt der Lösung im Salzlösegefaß etwa 6 Prozent beträgt. Andererseits kann aber auch zur Verminderung des Kalkgehaltes der wiedergewonnenen Salzlösung diese aus dem Filtermaterial entgegen der Filtrationsrichtung durch das Filtermaterial geleitet werden, wobei der erste, stärker kalkhaltige Anteil oberhalb der Filterschicht abgenommen und weggeleitet wird. Daraufhinwird die imFiltermaterialnochbefindliche Salzlösung durch Verdrängen mittels Wasser von unten nach oben in einen Salzlösebehälter geleitet und dann das Material, wie gewöhnlich, von oben nach unten entleert und ausgewaschen. Those that remain in the pore volume after leaching are only weak Saline-containing solutions can also be poured into the salt dissolving vessel. This A certain amount of table salt is now added to the amount of liquid obtained in this way, so that the salt content of the solution in the salt dissolver is about 6 percent. on the other hand but can also be used to reduce the lime content of the recovered salt solution this from the filter material against the direction of filtration through the filter material are conducted, with the first, more calcareous portion above the filter layer is removed and diverted away. Then the one that is still in the filter material Salt solution by displacing it with water from bottom to top into a salt dissolving container and then, as usual, emptied the material from top to bottom and washed out.
Ein Teil des Auswaschwassers kann gegebenenfalls auch in das Salzlösegefäß übergeführt werden. Der gesamten wiedergewonnenen Lösung wird dann die entsprechende Menge frischen Salzes zugefügt.Some of the wash-out water can optionally also be placed in the salt dissolving vessel be transferred. The total recovered solution then becomes the corresponding one Lots of fresh salt added.
