 deren Rand niedriger ist als der äussere Schalenrand, damit die auf ihrem Wege über das ganze Schalensystem vorkonzentrierte Säure aus der Mitte der untersten Schale ablaufen könne. 



   Bei der in Fig. 1 veranschaulichten Anordnung umspülen die aus dem Kessel a entweichenden heissen Säuredämpfe die Schalen f im wesentlichen nur von aussen, bei der Anordnung gemäss Fig. 2 sind sie dagegen ihrer ganzen Masse nach gezwungen, durch die zentrale Öffnung der untersten Schale /hindurchzutreten und auch den Boden der auf dieser ruhenden   nächsthöheren   Schale zu bestreichen. 



   Um die Leistungsfähigkeit des Apparates zu erhöhen, kann allenfalls ein heisser Luftstrom durchgeblasen bzw. durchgesaugt werden. Gewünschtenfalls kann auch, obzwar sich die ganze Konzentration in einem einzigen Kessel   durchführen lässt,   eine Kombination mehrerer nebeneinander oder hintereinander geschalteter Kessel hiefür in Verwendung kommen. 



   Der Einlauf der schwachen Säure, die in dem Apparat zur Konzentration gelangen soll, erfolgt bei k auf die oberste   Schale,/'.   Die Säuredämpfe von der ganzen Konzentration entweichen aus dem Apparat durch d und können entweder in bekannter Weise einem Kühler zugeführt oder behufs weiterer Ausnutzung ihrer Wärme der vorliegenden Erfindung gemäss in einen neben dem Apparat angeordneten Turm aus säurefestem Material, der mit kalter Säure berieselt wird, geleitet werden. Man erhält dann von diesem Turm die zur Berieselung verwendete schwache Säure, vermehrt um das kondensierte Destillat in heissem Zustande.

 the edge of which is lower than the outer edge of the bowl, so that the acid that has been pre-concentrated on its way over the entire bowl system can run off from the middle of the lowest bowl.



   In the arrangement illustrated in FIG. 1, the hot acid vapors escaping from the boiler a wash around the bowls f essentially only from the outside; in the arrangement according to FIG. 2, on the other hand, their entire mass is forced through the central opening of the lowest bowl / to step through and also to coat the bottom of the next higher bowl resting on this.



   In order to increase the efficiency of the device, a stream of hot air can be blown or sucked through. If desired, although the entire concentration can be carried out in a single tank, a combination of several tanks connected next to one another or one behind the other can be used for this.



   The weak acid, which is to be concentrated in the apparatus, enters the uppermost bowl at k, / '. The acid vapors from the entire concentration escape from the apparatus through d and can either be fed to a cooler in a known manner or, for further utilization of their heat, according to the present invention, passed into a tower made of acid-resistant material next to the apparatus, which is sprinkled with cold acid will. The weak acid used for sprinkling is then obtained from this tower, plus the condensed distillate in a hot state.

PATENT-ANSPRUCH : Verfahren zum Konzentrieren von Schwefelsäure in gusseisernen Apparaten, dadurch gekennzeichnet, dass die im Vorkonzentrator Zlr Konzentration gelangende, im Gegenstrom zu den abziehenden heissen Säuredämpfert einlaufende Säure über ein System von übereinander angeordneten Schalen (f) oder über ei aus einem Stück hergestellte Kaskade läuft und der aus Gusseisen bestehende Mantel des Vorkonzentrators zur Verhinderung der Kondensation der das Eisen angreifenden schwachen Säuredämpfe von aussen durch Heizgase erhitzt wird. PATENT CLAIM: Process for concentrating sulfuric acid in cast-iron apparatus, characterized in that the acid coming into the pre-concentrator Zlr concentration and entering in countercurrent to the hot acid dampers that are drawn off runs over a system of bowls (f) arranged one above the other or over a cascade made from one piece and the The cast iron jacket of the pre-concentrator is heated from the outside by heating gases to prevent condensation of the weak acid vapors attacking the iron.
