Description

Verfahren zum Auswaschen der Kohlensäure aus Faulgasen innerhalb des Schlammfaulraums. Die aus Faulräumen entweichenden Gase bestehen hauptsächlich aus Methan und Kohlensäure. Der größte Teil der Kohlensäure läßt sich durch Auswaschen beseitigen. Am bequemsten geschieht dies in den Faulräumen selbst, indem man das über dem faulenden Schlamm -stehende Wasser erneuert. Die Waschwirkung des im Faulraum befindlichen Wassers ist um so stärker, je weniger Kohlensäure in dem Wasser enthalten ist, und zwar kommt es darauf an, daß namentlich die oberste Wasserschicht, die von den aufsteigenden Gasblasen zuletzt durchlaufen wird, am wenigsten. Kohlensäure enthält. Dieser Forderung wird man am besten dadurch gerecht, daß man das Waschwasser von oben aus unmittelbar unter der Haube des Gas,-fängers in der Nähe des Wasserspiegels in den Faulraum einführt und das mit Kohlensäure angereicherte Waschwasser an einer tieferen Stelle des Faulraumes wieder abfließen läßt.Process for washing out the carbon dioxide from digester gases within the Sludge digestion. The gases escaping from septic tanks mainly consist of Methane and carbonic acid. Most of the carbonic acid can be washed out remove. The most convenient way to do this is in the septic tanks themselves, by doing the The water standing above the rotting mud is renewed. The washing effect of the septic tank The lower the amount of carbon dioxide in the water, the stronger it is is, and what matters is that the uppermost layer of water, the is passed through last by the ascending gas bubbles, least of all. carbonic acid contains. The best way to meet this requirement is to use the washing water from above directly under the hood of the gas trap near the water level introduces into the digester and the carbonated wash water to one can drain away from the deeper part of the septic tank.
