Description

Herstellung von Phosphorsäure. Bei der Herstellung von Phosphorsäure durch Verbrennung von Phosphor oder phosphorhaltigen Gasgemischen mit Luft findet durch die großeWärmeentwicklung einstarker Angriff der Ausmauerung der Verbrennungskammer statt.Production of phosphoric acid. In the manufacture of phosphoric acid by burning phosphorus or gas mixtures containing phosphorus with air A strong attack on the lining of the combustion chamber due to the large amount of heat generated instead of.

Es wurde gefunden, daß man diesen Angriff wirksam vermeiden kann, wenn man die Wand der Verbrennungskammer mit Phosphorsäure ständig berieselt, wobei gleichzeitigwenigstens eine teilweise Absorption des bei der Verbrennung entstehenden Phosphorpentoxyds stattfindet. Man kann die Berieselung in verschiedener Form -ausführen, z. B. in der Art, daß man die Verbrennungskammer als horizontal liegendes Drehrohr ausbildet, in dem aus einem Vorrat von Phosphorsäurelösung ein Teil durch die Bewegung des Rohres, gegebenenfalls unter Verwendung an sich bekannter Hilfsmittel, immer mit hochgenommen wird. Eine andere Ausführungsart besteht darin, daß man die Reaktionsgase, gegebenenfalls als Flamme, in einen senkrechten Schacht von unten oder von oben hineinführt, dessen Wände mit der Phosphorsäurelösung bespült werden.It has been found that this attack can be effectively avoided by if the wall of the combustion chamber is continuously sprinkled with phosphoric acid, whereby at the same time at least a partial absorption of the combustion produced Phosphorus pentoxide takes place. The sprinkling can be carried out in different ways, z. B. in the way that the combustion chamber as a horizontally lying rotary tube forms, in which a part from a supply of phosphoric acid solution by the movement of the pipe, if necessary using aids known per se, always is picked up with. Another embodiment is that the reaction gases, possibly as a flame, into a vertical shaft from below or from above leads into it, the walls of which are rinsed with the phosphoric acid solution.
