Description

Verfahren zur Gewinnung von Bleiweiß Im Patent 855 434 ist ein Verfahren zur Herstellung von Bleiweiß geschützt, bei dem Bleiacetatlösungen in feinverteilter Form, z. B. durch Nebeldüsen mit gasförmigem C 02, das ebenfalls durch Düsen zugeleitet wird, reagiert und das ausgefällte Bleiweiß kontinuierlich abgeführt wird. Hierbei können vorgewärmte C 02-Gase verwendet und weitere heiße inerte Gas.-. zugeleitet werden. Es ist auch möglich, die Abscheidung des Bleiweißes durch Ultraschall zu beschleunigen. Das so abgeschiedene Bleiweiß wird zweckmäßig unter Anbringung von Schabern oder Schnecken im Reaktionsgefäß ausgetragen.Process for the production of white lead In the patent 855 434 is a process Protected for the production of white lead, in which lead acetate solutions in finely divided Shape, e.g. B. by mist nozzles with gaseous C 02, which is also fed through nozzles reacts and the precipitated white lead is continuously removed. Here Preheated C 02 gases and other hot inert gas can be used. forwarded will. It is also possible to use ultrasound to separate the white lead accelerate. The white lead deposited in this way is expediently attached by Scrapers or screws discharged in the reaction vessel.

Es wurde nun gefunden, daß eine besonders zweckmäßige Ausführungsform dieses Verfahrens darin besteht, die in bekannter Weise hergestellte Bleiacetatlösung mittels eines Injektors aus dem Aufbewahrungsgefäß abzusaugen, wobei die treibende Kraft in dem Injektor das CO"-Gas ist, welches die Lösung beim Durchfließen durch den Injektor mit sich reißt. Entsprechend dem Druck des Gases und der Größe der Austrittsöffnung wird die Lösung fein verteilt dem Angriff des CO2-Gases ausgesetzt. Der Vorteil dieses Verfahrens besteht in einer besonders innigen Vermischung von Bleiacetat und C02, wodurch sich das Bleiweiß bildet.It has now been found that a particularly useful embodiment this method consists in using the lead acetate solution prepared in a known manner suction from the storage vessel by means of an injector, the driving The force in the injector is the CO "gas that the solution flows through pulls the injector with it. According to the pressure of the gas and the size of the At the outlet opening, the solution is finely distributed and exposed to the attack of the CO2 gas. The advantage of this process is a particularly intimate mixing of Lead acetate and C02, which forms the white lead.

Eine weitere Verbesserung des Verfahrens wird dadurch erreicht, daß die Reaktionsmischung, in der das Bleiweiß gebildet ist, einer Trockentrommel oder einer anderen Trockeneinrichtung zugeblasen wird, aus denen es mit dem erforderlichen Trockengrad entnommen werden kann.A further improvement of the process is achieved in that the reaction mixture in which the white lead is formed, a drying drum or Another drying device is blown, from which it is with the required Degree of dryness can be taken.
