Verfahren zur Gewinnung von Ammoniaksalzen.
Im Stammpatent Nr. 116369 ist ein Verfahren für die Gewinnung von Ammoniaksalzen beschrieben, nach welchem die zur Reaktion mit dem Ammoniak zu bringende Säure in einer Ammoniakatmosphäre äusserst fein verstäubt wurde. Die entwickelte Reaktionswärme rief die Verdampfung des in der Säure enthaltenen Wassers herbei und der Dampf wurde durch EinfÜhrung in eine Rektifiziersäule entfernt, deren oberer Teil mit einem Kühler versehen war.
Die verdichtete Ammoniaklösung gab beim Herabfallen auf die unteren Flächen und durch Kontakt mit den aus dem Reaktionsraume kommenden heissen Gasen wieder das gasförmige Ammoniak ab, während das erschöpfte Wasser am Boden der Rektifiziersäule abfloss.
Dieses Verfahren erforderte die Verwendung eines Ventilators, um den Umlauf der Gase in der Rektifiziersäule rege zu erhalten.
Die verbesserte Verbesserung bezweckt, den Ventilator sowie die Rektifikationskolonne und den Kühler entbehrlich zu machen.
Das neue Verfahren ist an Hand der in anliegender Zeichnung schematisch dargestellten Anordnung näher erläutert.
Die Säure gelangt durch den Rohrstutzen E in den Behälter B, von wo sie durch den Überlauf F tritt und vermittels eines geeigneten Zerstäubers G in den Reaktionsraum A eingespritzt wird.
Die Säure soll eine derartige Konzentration aufweisen, dass die während der Reaktion mit dem Ammoniak entwickelte Wärme ausreicht, das in ihr enthaltene Wasser vollständig zum Verdampfen zu bringen.
Das sich dabei bildende trockene Salz sammelt sich am Boden der Säule an und wird durch eine Förderschnecke C ausgetragen. Das Ammoniak wird in entwässerter Form in das Rohr H eingebracht und verteilt sich am Boden des Reaktionsraumes.
Der während der Reaktion entwickelte Dampf, der einen merklichen Prozentsatz NH3 enthält, tritt durch das Rohr D aus und wird nach der in die Säure im Behälter B eintauchenden Spritzdüse L gedrückt. Derart wird das vorhandene NH3 durch die Säure gebunden, während der Dampf direkt ins Freie entweicht.
Die Spritzdüse kann auch durch einen Turm ersetzt sein, in welchem die Säure von oben als Regen hineintropft.
Das Manometer 1 dient zur Kontrolle des im Innern des Reaktionsraumes herrschenden Druckes.

Process for the production of ammonia salts.
The parent patent no. 116369 describes a process for the production of ammonia salts, according to which the acid to be reacted with the ammonia was atomized extremely finely in an ammonia atmosphere. The heat of reaction evolved caused the water contained in the acid to evaporate and the steam was removed by introducing it into a rectification column, the upper part of which was provided with a condenser.
The compressed ammonia solution released the gaseous ammonia when it fell on the lower surfaces and through contact with the hot gases coming from the reaction space, while the exhausted water flowed off at the bottom of the rectification column.
This procedure required the use of a fan to keep the gases circulating in the rectification column.
The aim of the improved improvement is to make the fan and the rectification column and the condenser superfluous.
The new method is explained in more detail with reference to the arrangement shown schematically in the attached drawing.
The acid passes through the pipe socket E into the container B, from where it passes through the overflow F and is injected into the reaction chamber A by means of a suitable atomizer G.
The acid should have such a concentration that the heat developed during the reaction with the ammonia is sufficient to completely evaporate the water it contains.
The dry salt that forms in the process collects at the bottom of the column and is discharged by a screw conveyor C. The ammonia is introduced into the tube H in dehydrated form and is distributed over the bottom of the reaction space.
The vapor evolved during the reaction, which contains a noticeable percentage of NH3, exits through tube D and is pushed towards the spray nozzle L, which is immersed in the acid in container B. In this way, the existing NH3 is bound by the acid, while the steam escapes directly into the open.
The spray nozzle can also be replaced by a tower into which the acid drops from above as rain.
The pressure gauge 1 is used to control the pressure inside the reaction chamber.
