Das neue Verfahren besteht darin, daß die vom Zellstoffkocher abfließende heiße Lauge in einem Behälter durch ihren eigenen Druck zerstäubt wird, so daß sich die schweflige Säure abspaltet und nach oben abzieht. Die abziehende schweflige Säure kann dann zur Bereitung von Frischlauge verwendet werden, während die entsäuerte Lauge aus dem Behälter unten abfließt.The new process consists in the hot liquor flowing off from the digester is atomized in a container by its own pressure, so that the sulphurous Splits off acid and withdraws upwards. The withdrawing sulphurous acid can then be used Preparation of fresh liquor can be used while the deacidified liquor from the container drains below.
ίο Die neue Vorrichtung besteht in einem in die Ablaugenleitung der Zellstoffkocher eingebauten Behälter, der mit Zerstäubungsvorrichtungen für die Lauge und oben mit einem Gasabzugsrohr versehen ist.ίο The new device consists of an in the waste liquor line of the digester built-in container, the one with atomizing devices for the lye and is provided with a gas exhaust pipe at the top.
Die Zeichnung stellt die Vorrichtung zur Ausführung des neuen Verfahrens durch die Fig. i, 2 und 3 im Aufriß, in der Seitenansicht und im Grundriß dar; die Fig. 4 und 5 geben andere Ausführungsformen der Vorrichtung wieder; Fig. 6 zeigi den Entgaser in Verbindung mit dem Zellstoffkocher und der Laugenbereitung.The drawing represents the device for carrying out the new method by the Figures i, 2 and 3 show in elevation, side view and plan; FIGS. 4 and 5 show other embodiments of the device; Fig. 6 shows the degasser in connection with the cellulose digester and the lye preparation.
Die Lauge wird nach beendeter Zellstoffkochung abgelassen, strömt unter einem Druck von ι bis 2 Atm. mit einer Temperatur von 120 bis 130 ° C. aus dem Zellstoffkocher k durch das Rohr c und wird nun in dem Behälter α zerstäubt. Dabei spaltet sich die schweflige Säure ab, welche durch das Rohr h weitergeführt wird, und zwar durch einen Kühler m nach dem Laugenbottich n, wo sie zur Bildung oder Verstärkung von Frischlauge dient. Was von der Säure in dem Bottich η nicht absorbiert wird, zieht durch durch das Rohr 0 nach den Türmen f ab, -35 um hier vollends aufgesogen zu werden. Die entsäuerte Lauge fließt aus dem Behälter a durch das Rohr i nach unten ab, um mit den übrigen Fabrikwässern vermischt in den Fluß geführt zu werden.The lye is drained off after the pulp boiling has ended and flows under a pressure of ι to 2 atm. at a temperature of 120 to 130 ° C. from the digester k through the pipe c and is now atomized in the container α. The sulphurous acid is split off, which is carried on through the pipe h , namely through a cooler m after the caustic tub n, where it is used to form or strengthen fresh caustic. What is not absorbed by the acid in the vat η is drawn off through the pipe 0 to the towers f -35 in order to be completely absorbed here. The deacidified liquor flows down from the container a through the pipe i to be mixed with the rest of the factory water in the river.
Das Zerstäuben der Lauge geschieht in dem schmalen Behälter a. In demselben liegt unten das Rohr b, dem' die Ablauge der Kocher durch das Rohr c zufließt. Auf dem Verteilungsrohr b sitzen die Zerstäuber, die aus oben geschlossenen Rohren d mit gegen die Wände e des Behälters α gerichteten Spritzlöchern f bestehen. Die Lauge tritt durch die Löcher f aus und zerstäubt sich an den Wänden e. Die sich dabei abspaltende schweflige Säure füllt den oberen Raum des Behälters α aus, tritt in den Gassammler g und zieht durch Rohr h ab. Die entsäuerte Lauge fließt an den Wänden e ab, sammelt sich im unteren Teil des Behälters a an und fließt durch Rohr i ab.The lye is atomized in the narrow container a. In the same is below the pipe b, to which 'the waste liquor from the digester flows through the pipe c . On the distribution pipe b sit the atomizers, which consist of pipes d closed at the top with spray holes f directed against the walls e of the container α . The lye exits through the holes f and is atomized on the walls e. The sulphurous acid which is split off in the process fills the upper space of the container α , enters the gas collector g and is withdrawn through tube h . The deacidified lye flows off the walls e , collects in the lower part of the container a and flows off through pipe i .
Das gewonnene Gas kann man in der Weise trocknen, daß man das Gas, wie in Fig. 1 gestrichelt angedeutet, auf dem Wege zur Laugenbereitung das Zuleitungsrohr für die heiße Lauge umspülen läßt.The gas obtained can be dried in such a way that the gas, as in FIG. 1 indicated by dashed lines, on the way to the caustic preparation the supply pipe for the hot lye to wash around.
Das Gefäß α kann auch zylindrisch, wie Fig. 4 zeigt, oder sternförmig nach Fig. 5 ausgeführt werden. Die Größe der Entgaser-The vessel α can also be designed to be cylindrical, as shown in FIG. 4, or in a star shape according to FIG. 5. The size of the degasser
einrichtung richtet sich nach der Menge der von den Kochern abgehenden Lauge.The set-up depends on the amount of lye leaving the cookers.
