Description

Verfahren zur kontinuierlichen Herstellung von wasserfreiem Natriumsulfat. Es ist bekannt, daß Glaubersalz (Na. SO, - i o H, 0) bei Erhitzung auf 32,4' wasserfreies Natriums,alfat (Na.S0,) ausscheidet. Diese Tatsache wird benuizt zu nachstehendem Verfahren: Bei an sich bekannten rotierenden Filtern wird in dem Filtertrog, aus dem sich die Filtertrommel ihr Material saugt, das kontinuierlich eingetragene Glaubersalz mit üb- lichen Mitteln erhitzt, oder es wird ihm bereits crhitzt zugeführt. Das sich über 32,4' C ausscheidende wasserfreie Natriumsulfat wird durch ein im Filtertrog an sich bekanntes Rührwerk verhindert, sich zu Boden zu setzen. Dieses Gemenge von Mutterlauge und wasserfreiem Natriumsulfat wird auf dem rotierenden Filter abgesaugt. Der Filterkuchen, bestehend aus wasserfreiem Natriumsulfat, wird in bekannter Weise entfernt nach gegebenenfalls vorherigem Waschen mit heißer Mutterlauge, wie dies bei rotierenden Filtern in bekannter Weise geschieht.Process for the continuous production of anhydrous sodium sulfate. It is known that Glauber's salt (Na. SO, - 10 H, 0 ) is excreted when heated to 32.4 'anhydrous sodium, alfate (Na SO,). This fact is used for the following process: In the case of rotating filters known per se , the continuously introduced Glauber's salt is heated in the filter trough from which the filter drum sucks its material by conventional means, or it is supplied to it already heated. The anhydrous sodium sulphate which separates out above 32.4 ° C. is prevented from settling on the ground by an agitator known per se in the filter trough. This mixture of mother liquor and anhydrous sodium sulfate is sucked off on the rotating filter. The filter cake, consisting of anhydrous sodium sulfate, is removed in a known manner after, if necessary, previous washing with hot mother liquor, as is done in a known manner with rotating filters.
