PATENTAMT.PATENT OFFICE.

Der Gegenstand vorliegender Erfindung betrifft ein Verfahren zur Nutzbarmachung der beim Rösten schwefelhaltiger Erze entstehenden schwefligen Säure, um den darin enthaltenen Schwefel zu gewinnen.The subject matter of the present invention relates to a method for utilizing the When roasting sulfur-containing ores, the sulphurous acid formed in order to reduce the amount contained in them To gain sulfur.
Die schweflige Säure wird zuerst in bekannter Weise durch Reduction vermittelst Kohlenstoffes und Wasserstoffes in Schwefelwasserstoff umgesetzt. Die. beim Rösten entstehenden Gase enthalten zwar aufser dem Schwefligsäureanhydrid, dem Stickstoff und freiem Schwefel auch Schwefelarsen und Schwefelantimon, welche wahrscheinlich an den chemischen Vorgängen theilnehmen, was indessen wenig zu bedeuten hat, da die Arsen- und Antimonverbindungen, welche sich später in einem Ueberschufs von feuchtem Schwefelwasserstoff verdichten können, nur als Schwefelverbindungen vorhanden sind.The sulphurous acid is first imparted in a known manner by reduction Carbon and hydrogen converted into hydrogen sulfide. The. resulting from roasting In addition to sulfurous acid anhydride, gases contain nitrogen and Free sulfur also includes arsenic and sulfur antimony, which are likely to have take part in the chemical processes, which, however, has little significance since the Arsenic and antimony compounds, which are later found in an excess of moist Hydrogen sulfide can compress only when sulfur compounds are present.
Auf den so gewonnenen.Schwefelwasserstoff wird eine frisch zugeführte, von Arsen und Antimon freie Menge Schwefligsäureanhydrit zur Einwirkung gebracht:On the hydrogen sulfide obtained in this way a freshly added amount of sulfurous acid anhydrite free of arsenic and antimony is added brought into effect:
SO2 + 2 K2 S = 3 S+ 2 H2O. SO 2 + 2 K 2 S = 3 S + 2 H 2 O.
Diese Reaction ist nicht unbekannt, konnte jedoch bis jetzt nicht praktisch durchgeführt werden; eine praktische Durchführung wird jedoch durch das vorliegende Verfahren erzielt, bei welchemThis reaction is not unknown, but has not yet been carried out in practice will; however, practical implementation is achieved through the present procedure, in which
1. die Mischung der Gase im trockenen Zustande geschehen mufs, 1. the gases must be mixed in the dry state,
2. der Wasserdampf erst dann zugefügt wird, wenn eine homogene Mischung erzielt worden ist,2. The steam is only added when a homogeneous mixture has been achieved is,
3. die Temperatur wenigstens ioo° beträgt.3. the temperature is at least 100 °.
Hiernach werden die Gase, welche Schwefelwasserstoff und event, flüchtige Arsen- und Antimonverbindungen, sowie Staub enthalten, zuerst abgekühlt, wodurch die verdichtbaren Verbindungen sich zugleich mit dem Staub niedersetzen. Zum Hervorbringen dieser Abkühlung macht man Gebrauch von Cementleitungen, welche in Wasser eingetaucht sind und welche während ihrer Thätigkeit durch Wasserstöfse gereinigt werden.According to this, the gases, which hydrogen sulfide and eventual, volatile arsenic and Antimony compounds, as well as containing dust, are first cooled, making the compressible Connections sit down at the same time as the dust. To bring about this cooling use is made of cement pipes which are immersed in water and which are passed through during their operation Hydrogen must be cleaned.
Die so abgekühlten Gase gehen sodann in einen oder mehrere Thurmbehälter über, welche mit Chlorcalcium in porösen Stücken und von genügendem Durchschnitt, damit die Schnelligkeit der Gase 50 cm pro Secunde nicht übertrifft, angefüllt sind, um so ein hinlängliches Trocknen, sowie zugleich Filtriren der Gase zu bewirken.The gases cooled in this way then pass into one or more tower containers, which with calcium chloride in porous pieces and of sufficient size to allow rapidity of gases not exceeding 50 cm per second, are filled so as to be sufficient To effect drying, as well as filtering the gases at the same time.
Die nunmehr getrockneten und filtrirten Gase werden mit Schwefligsä'ureanhydrit gemischt. Vorzuziehen ist das Schwefligsäureanhydrit, welches beim Rösten reiner Erze entsteht, d. h. weder Arsen noch Antimon enthält.The gases, now dried and filtered, are mixed with sulphurous anhydrite. Sulfurous anhydrite, which is produced when roasting pure ores, is preferable. H. contains neither arsenic nor antimony.
Das Schwefligsäureanhydrit wird zuerst abgekühlt, getrocknet und filtrirt, indem es durch Thurmbehälter geht, welche mit von cone. Schwefelsäure berieseltem Koks angefüllt sind. Das Schwefligsäureanhydrit wird sodann dem Schwefelwasserstoff, welcher ebenfalls, wie oben angegeben, gereinigt worden ist, hinzugefügt; die gemischten Gase werden sodann in eine Serie abwechselnd auf- und absteigender Kanäle geleitet, welche zugleich einen Recuperator bilden und die Temperatur des Gemisches auf ioo° C. oder etwas höher bringen.The sulfurous anhydrite is first cooled, dried, and filtered by pouring it through Tower container goes, which with cone. Sulfuric acid sprinkled coke are filled. The sulfurous anhydrite is then the hydrogen sulfide, which also, as above indicated, has been cleaned, added; the mixed gases are then converted into a Series of alternating ascending and descending channels, which at the same time have a recuperator and bring the temperature of the mixture to 100 ° C. or a little higher.
