Description

Gewinnung von Salzsäure aus den Chloridendlaugen der Bleicherdefabriken und ähnlicher Industrien. Die Erfindung betrifft eine Ausführungsform des durch Patent 449 993 geschützten Verfahrens, wonach die Rückgewinnung der Salzsäure aus den Chloridendlaugen . der Bleicherdefabriken in mindestens zwei sich grundsätzlich voneinander unterscheidenden Abschnitten durchgeführt wird: und der erste Abschnitt der möglichst weitgehenden. Eindickung der Endlauge, der zweite dagegen der eigentlichen Rückgewinnung der Säure durch Zersetzung dient.Extraction of hydrochloric acid from the final chloride liquors in the bleaching earth factories and similar industries. The invention relates to an embodiment of the by Patent 449 993 protected process, according to which the recovery of hydrochloric acid from the final chloride liquors. the bleaching earth factories in at least two in principle different sections is carried out: and the first section the most extensive. Thickening of the final liquor, the second, on the other hand, the actual The acid is recovered by decomposition.

Das vorliegende Verfahren ist dadurch gekennzeichnet, daß die Endlauge im Verdampfung s- bzw. Zersetzungsraum oder in beiden zugleich durch. eine Koksschicht verteilt wird, die in dem Maß, wie sie sich beim Betrieb mit einer Kruste von Oxyden oder festen C'hJcriden überzieht, von oben. her erneuert wird, während die unterste Schicht durch einen geeigneten Rost in die Feuerung fällt oder nach Art des Füllafensystems selbst, tätig im Maße des Abbrandes in die Feuerung nachsinkt, um daselbst die zur Durchführung des Verfahrens nötige Wärme ganz oder teilweise zu liefern.The present process is characterized in that the final liquor in the evaporation or decomposition space or in both at the same time. a layer of coke that is distributed to the extent that it becomes when operating with a crust of oxides or solid C'hJcriden coated, from above. forth is renewed while the lowest Layer falls through a suitable grate into the furnace or according to the type of filling tube system himself, active to the extent of the burn, sinks into the furnace, around the to the To carry out the process to deliver the necessary heat in whole or in part.
