   Bei Einhaltung der vorstehend erläuterten Arbeitsweise wird die an sich bekannte Erzeugung von Schwefelsäure in mit nitroser Schwefelsäure berieselten   Reaktionstürmen   erst wirtschaftlich gestaltet und die Intensität des Prozesses derart gesteigert, dass die Leistung eines gegebenen Reaktionsraumes etwa das Zehnfache von derjenigen eines entsprechenden Bleikammerraumes beträgt. 



   PATENT-ANSPRÜCHE : 
1. Ausführungsart des Verfahrens zur raschen Erzeugung von Schwefelsäure ohne Anwendung von   Bloikammern   durch Einwirkung von schwefliger Säure auf nitrose Schwefelsäure gemäss Stammpateni Nr. 3 6098, dadurch   gekennzeichnet, dass man die schwefligsäure-   hältigen Gase durch eine Reihe von   Reaktionsturmen   leitet, welche mit nitroser Schwefelsäure intensiv berieselt werden, wobei zum Heben und Zerstäuben der nitrosen Säure   Säure-Emulseure   dienen, die teils mit komprimierten Kiesofengasen, teils mit Luft betrieben werden und so eingerichtet sind, dass sie auch das für den Prozess nötige Wasser bezw. die Salpetersäure mit auf die Türme befördern, und dass das in ihnen enthaltene Säuregemisch durch Luft oder Wasser gekühlt werden kann.

   If the procedure described above is adhered to, the production of sulfuric acid, known per se, in reaction towers sprinkled with nitrous sulfuric acid is first made economical and the intensity of the process is increased in such a way that the output of a given reaction chamber is about ten times that of a corresponding lead chamber.



   PATENT CLAIMS:
1. Type of execution of the process for the rapid production of sulfuric acid without the use of Bloi chambers by the action of sulfurous acid on nitrous sulfuric acid according to Stammpateni No. 3 6098, characterized in that the gases containing sulfuric acid are passed through a series of reaction towers which are filled with nitrous sulfuric acid intensely sprinkled, whereby acid-emulsifiers are used to lift and atomize the nitrous acid, which are operated partly with compressed gravel furnace gases, partly with air and are set up in such a way that they also have the water or water required for the process. transport the nitric acid to the towers and that the acid mixture they contain can be cooled by air or water.

2. Zur Durchführung der unter Anspruch 1 angegebenen Ausführungsart, des Verfahrens nach Stammpatent Nr. 36098 die Anordnung mehrerer (vorteilhaft 46) miteinander zu einem Turmsystem verbundenen Reaktionstürme, welche derart zusammenarbeiten, dass in dem betreffenden Turmsystem den der Eintrittsseite der schwefligsäurehältigen Gase näher gelegenen Reaktionstürmen die von den anderen Türmen erzeugten nitrosen Säuren zugeführt werden, während die erstgenannten Türme ihrerseits wieder einen Teil der in ihnen gebildeten Schwefelsäure an die im Sinne der Strömungsrichtung der Reaktionsgase eut f nteren Türme abgeben, um in diesen die Absorption des bei der Schwefelsäurebildung frei gewordenen Stickoxyds bezw. 2. To carry out the embodiment specified under claim 1, the method according to parent patent no. 36098, the arrangement of several (advantageously 46) reaction towers connected to one another to form a tower system, which work together in such a way that the reaction towers located closer to the inlet side of the gases containing sulfuric acid in the tower system concerned the nitrous acids produced by the other towers are fed in, while the first-mentioned towers in turn release part of the sulfuric acid formed in them to the towers further farther in terms of the direction of flow of the reaction gases in order to absorb the nitrogen oxide released during the formation of sulfuric acid respectively der aus demselben durch Oxydation entstandenen salpetrigen Säure herbeizuführen. the nitrous acid produced from it by oxidation. 3. Weitere Ausbildung des aus mehreren miteinander verbundenen Reaktionstürmen bestehenden Turmsystems nach Anspruch 2, dadurch gekennzeichnet, dass dem zu verwendenden Turmsystem behufs Nutzbarmachung der bei dem Prozess freiwerdenden Wärme ein Konzentrationstunu zur Erzielung von piger Schwefelsäure vorgeschaltet ist. 3. Further formation of the tower system consisting of several interconnected reaction towers according to claim 2, characterized in that the tower system to be used is preceded by a concentration step to achieve piger sulfuric acid in order to utilize the heat released during the process.
