Description

Vorrichtung zum Fällen eines hochbasischen Bleicarbonats hoher Deckkraft Bei dem bisher üblichen Fällen von Blei-( basischem Bleicarbonat) aus Bleilaugen durch Einleiten von Kohlenoxyd unter Rühren wurde ein einheitliches Erzeugnis liöclistmöglichei- Deckkraft nicht erreicht. lin Gegensatz flazu führt die neue Vorrichtung zu einem einheitlich zusammengesetzten hochbasischen Bleicarbonat, das dem liislierigrit l-'ällungslileiweif an Declzkraft überlegen ist.Device for felling a highly basic lead carbonate with high opacity In the previously common cases of lead (basic lead carbonate) from lead lye by introducing carbon oxide with stirring, a uniform product was possible. Opacity not reached. lin unlike flazu, the new device leads to a uniformly composed highly basic lead carbonate, the liislierigrit l-'ällungslileiweif is superior to Declzkraft.

Die neue Fällvorrichtung besteht au: einem die Bleilauge aufnehmenden Behälter, zweckmäßigerweise in Form eines senkrecht stehenden 7"-linders, in dem, zweckmäßigerweise konzentrisch, ein ebenfalls senkrchter, zylindrischer: um seine Längsachse drehbarer Gitterkorb angeordnet ist. Der Gitterkorb kann z. B. durch senkrechte, den Gas- und Laugendurchtritt gestattende Stäbe gebildet werden. Er ist mit Füllkörpern in Form kurzer Rohrstücke beschickt. Günstige -Maße für die Rohrstücke sind z. B. etwa ro bis i; cnt Länge bei 3 bis 3 cm Durchmesser und o,@ bis 3 nUn Wandstärke. In et«-a halber Hölie des Bleilaugenbehälters bzw. des Gitterkorbes befinden sich die bei!len feststehenden Kohlendio-",-,-dzuführttngsrolire, deren erweiterte, düsen- oder brausenartig ausgebildeten Enden bis an den Gitterkorb heranreichen und diesen an zwei diametral entgegengesetzten Stellen seines Umfanges backenartig bedecken bz«-. sich an ihm anlegen. Durch den rotierenden, mit Füllkörpern beschickten Gitterkorb wird eine gleichmäßige Verteilung des zugeführten 1%olilendiolvds und eine @-erl<in- gerung dessen Einz%-irl:un-sdauer auf die Blei- lauge erreicht, so daß man nicht, wie bisher, mit einem großen 1@olilendioxvdiiiierscliul:l arbeiten muß. Demzufolge erhält inan ein gleichförmiges, einheitlich zusammengesetz- tes hochbasisches I3leicarbonat, das, als Blei- weiß verwendet, eine bessere Deckkraft als die bisher üblichen Bleiweile zeigt. Die Abbildung zeigt schematisch die neue Vorrichtung. In dein die Bleilauge a aufneh- inenden Behälter h befindet sich der mit Füll- körpern c beschickte und z.

The new felling device consists of: a container holding the lead lye, expediently in the form of a vertical 7 "linder, in which, expediently concentrically, a likewise vertical, cylindrical mesh basket is arranged which can be rotated about its longitudinal axis. are formed by vertical rods that allow gas and alkali to pass through. It is filled with fillers in the form of short pipe pieces. Up to 3 mm wall thickness. In half the hollow of the lead-lye container or the mesh basket are the fixed carbon dio - ", -, - dzuführtngsrolire, whose extended, nozzle-like or shower-like formed ends reach up to the mesh basket and cover it like a cheek at two diametrically opposite points of its circumference. mess with him.
