 die an den Prellblechen   9   zerstäubten Dampf- und Laugengemische von diesen in divergenten Richtungen   n zurückgeworfen werden,   wird erreicht, dass die sich bildenden Ablaugen sich bei dem Entweichen aus dem   Entspannungsgefäss   c nicht gegenseitig behindern, und somit der Bildung eines Überdruckes in dem   Entspannungsgefäss   e entgegentreten. Die Verdampfung der   zerstäubten   Lauge wird ferner dadurch begünstigt, dass durch Leitung h heisse Luft in die das Entspannungagefäss anfüllende Lauge hineingedrückt und hiedurch eine Wirbelung der Lauge hervorgerufen wird ; bei sauren Laugen (z.

 EMI2.1
 the vapor and alkali mixtures atomized on the baffle plates 9 are thrown back by these in divergent directions n, the result is that the waste liquors that are formed do not interfere with each other when they escape from the expansion vessel c, and thus counteract the formation of an overpressure in the expansion vessel e . The evaporation of the atomized liquor is further promoted by the fact that hot air is forced through line h into the liquor filling the expansion vessel, thereby causing the liquor to swirl; with acidic alkalis (e.g.

   Sulphite waste liquor) also leads to oxidation
 EMI2.2
 Lich the waste liquor remains in the vessel c in a highly concentrated state and is then drained off through line e for further treatment.

Claims (1)

PATENT-ANSPRÜCHE : 1. Verfahren zur Konzentrierung von Laugen, insbesondere von Sulfitablaugen, die kochend und unter Druck aus Kochern abgelassen werden, dadurch gekennzeichnet, dass die Laugen in geschlossenen Behältern unter Bildung von Abdampfen zunächst entspannt und dann der Einwirkung von Injektoren unterworfen werden, welche die mit Dampf vermischten Laugen zer- stäuben, 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die Laugen während der Entspannung durch Einführung heisser Druckluft in Wirbelung versetzt werden. PATENT CLAIMS: 1. A method for concentrating alkalis, in particular sulphite waste liquors, which are drained from boilers under pressure and boiling, characterized in that the alkalis are initially relaxed in closed containers with the formation of evaporation and then subjected to the action of injectors, which the steam dust mixed lye, 2. The method according to claim 1, characterized in that the alkalis are caused to swirl during the relaxation by introducing hot compressed air. 3. Vorrichtung zur Ausübung des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass das die entspannte Lauge aufnehmende geschlossene Gefäss (c) mit Injektorsaugleitungen (k) m Verbindung steht, und die Druckleitungen (in) der letzteren mit ihren düsenaltigen Ausmündungen (a) gegen im oberen Teil des Gefässes (c) vorgesehene Prellbleche (g) derart gerichtet sind, dass die an den Prellblechen (g) zerstaubten Dampf- und Laugengemische von den EMI2.3 3. A device for performing the method according to claim 1, characterized in that the closed vessel (c) receiving the expanded liquor is connected to injector suction lines (k) and the pressure lines (in) of the latter with their nozzle-like openings (a) against The baffle plates (g) provided in the upper part of the vessel (c) are directed in such a way that the steam and lye mixtures atomized on the baffle plates (g) from the EMI2.3
