Description

Verfahren zur Abscheidung von Phosphor aus Phosphordämpfen. Bei den für die Herstellung von Phosphor üblichen Verfahren bietet die Abscheidung des Phosphors aus den entstehenden Phosphordämpfen große Schwierigkeiten; die hauptsächlich in Nebelform vorhandenen Phospharteilchen setzen ihrer Abscheidung unter Wasser einen solchen Widerstand entgegen, daß man gezwungen ist, die Kondensation in komplizierten Apparaten, die mit einem sauerstofffreien Gas angefüllt sind, vorzunehtnen.Process for separating phosphorus from phosphorus vapors. Both The usual process for the production of phosphorus is the deposition of phosphorus great difficulties from the resulting phosphorus fumes; which are mainly in Phosphate particles present in the form of a mist begin their deposition under water such opposition that one is forced to turn the condensation into complicated ones Apparatus filled with an oxygen-free gas must be used.

Es hat sich nun gezeigt, daß man an Stelle dieser komplizierten und kostspieligen Verfahren auf verhältnismäßig einfache Weise die Abscheidung der Phosphornebelteilchen beuzrken kann, wenn man den Phosphordampf der ein- oder mehrmaligen elektrostatischen Einwirkung unterwirft, zweckmäßig, nachdem man ihn mit einer geeigneten Flüssigkeit (beispielsweise Wasser) in innige Berührung gebracht hat.It has now been shown that instead of these complicated and costly process in a relatively simple manner the separation of the phosphorus mist particles beuzrken, if one or multiple electrostatic phosphorus vapor Subjects to action, expediently, after having him with a suitable liquid (for example water) has brought into intimate contact.

Zu diesem Zwecke werden die heißen Phasphordämpfe einer geeigneten Waschvorrichtung zugeführt, die sie entgegen der Rieselt' durchströmen, um am anderen Ende gekühlt auszutreten, während sich die durch die Waschvorrichtung gehende Rieselfiüssigkeit dabei erhitzt. Der aus der Flüssigkeit aufsteigende Dampf umgibt, indem er sich im gekühlten Gebiet kondensiert, die Nebelteilchen als Flüssigkeitshülle, vergrößert sie und befähigt sie dadurch zur leichteren Abscheidung. Durch diese Vorbehandlung der Phosphordämpfe wird erzielt,- daß schon bei einmaligem Durchgang durch eine elektrostatische Abscheidungsvorrichtung eine rasche und vollständige Abscheidung der PhosphDrnebelteilchen erfolgt. Ausführungsb eispiel. Die von der Hauptkondensatiorisanlage des Phosphors kommenden Gase, die die schwer abscheidbaren Phosphornebel enthalten, treten in einen Tonturm, der mit Quarzitsteinen ausgefüllt ist, mit Wasser berieselt und auf einer Temperatur von über q.5° gehalten wird, unten ein und durchströmen hierauf einen zweiten Turm, der die Anordnung zur elektrostatischen Abscheidung der im Quarzitturm vergrößerten Phosphornebelteilchen enthält. Die elektrastatische Anordnung kann in bekannter Art geschehen, indem lediglich eine Anzahl gespannter Drähte oder Netze, die abwechselnd mit dem positiven und negativen Pol eines entsprechenden Hochspannungsnetzes verbunden sind, zur Abscheidung benutzt werden.For this purpose the hot phasphore vapors are a suitable one Washing device supplied, which they flow through against the trickle 'to the other Exit cooled at the end while the trickle liquid passing through the washing device is flowing heated in the process. The vapor rising from the liquid surrounds itself by itself condenses in the cooled area, the fog particles as a liquid envelope, enlarged them and thereby enables them to be separated more easily. Through this pre-treatment of phosphorus vapors is achieved - that already with a single passage through a electrostatic deposition device enables rapid and complete deposition of the phosphate mist particles takes place. Execution example. The one from the main condenser the gases coming from the phosphorus, which contain the phosphorus mist, which is difficult to separate, step into a clay tower filled with quartzite stones, sprinkled with water and is kept at a temperature of over q.5 °, flow in below and through then a second tower, which is the arrangement for electrostatic deposition which contains phosphorus mist particles enlarged in the quartzite tower. The electrostatic Arrangement can be done in a known manner by simply adding a number of tensioned Wires or nets alternating with the positive and negative pole of a corresponding one High voltage network are connected to be used for separation.
