Description

Verfahren zur Wiedergewinnung der beim Abgasen von Zellstoffkochern übertretenden Flüssigkeits- und Gasmengen. Es ist bekannt, die schweflige Säure und den Wärmeinhalt der Kocherabgase dadurch nutzbar zu machen, daß man die Abgase in geschlossene Druckbehälter einleitet, die mit einer wässerigen Lösung von doppelschwefelsaurem Kalk beschickt sind, von der die Gase aufgenommen werden. Diese mit SO. angereicherte Lauge wird dann in warmem Zustand zur Füllung neuer Kocher verwendet.Process for the recovery of waste gas from pulp digesters Overflowing liquid and gas quantities. It is known to have sulphurous acid and to make the heat content of the cooker exhaust gases usable by the fact that the exhaust gases in closed pressure vessel, which is filled with an aqueous solution of double sulfuric acid Lime are charged, from which the gases are absorbed. This with SO. enriched Lye is then used in a warm state to fill new cookers.

Nach dem neuen Verfahren werden dagegen die Abgase unter Ersparung aller Zwischenbehälter unmittelbar in einen anderen unter vollem Betriebsdruck stehenden Zellstoffkocher übergeführt. Zu diesem Zweck werden sie mittels Pumpe, Injektor oder durch ein anderes Beförderungsmittel in den zweiten Kocher gedrückt und dadurch sowohl Säuregehalt als Wärmeinhalt unmittelbar verwertet.According to the new process, on the other hand, the exhaust gases are reduced all intermediate containers directly into another one under full operating pressure Pulp digester transferred. For this purpose, they are pumped, injected or pushed into and through the second digester by some other means of conveyance both acidity and heat content are used directly.

Hat man auch früher schon aus Zellstoffkochern entweichende schwefligsaure Dämpfe unmittelbar einem zweiten Kocher zugeführt, so war doch der zweite Kocher in diesen. Fällen entweder gar nicht angeheizt, oder er stand nicht unter vollem Kochdruck. Infolgedessen war man in der Ausnutzung der Anlage beschränkt, während bei dem neuen Verfahren der zweite in Betracht kommende Kocher unter vollem Betriebsdruck steht. Die Kosten für einen oder mehrere geschlossene Zwischenbehälter werden damit erspart.Sulfuric acid escaping from cellulose digesters has also been found in the past If vapors were fed directly to a second cooker, that was the second cooker in these. Cases either not fueled at all or he was not under full Cooking pressure. As a result, one was limited in the use of the facility while in the new process the second digester under consideration under full operating pressure stands. The costs for one or more closed intermediate containers are thus saved.
