Beschreibung und Erläuterung zur Patentanmeldung 'Verfahren zur Neutralisation von entschwefeitern Rauchgas, vorzugsweise in Kühltürmen'.Description and explanation of the patent application 'Process for the neutralization of desulfurizers Flue gas, preferably in cooling towers'.
Es ist in der Literatur und in mehreren Patentanmeldungen beschrieben worden, daß es zweckmäßig ist, das Rauchgas aus Possilkraftwerken, das durch eine Entschwefelungsanlage vorgereinigt wurde, in Kühltürme einzuleiten und mit den Kühlturmabdämpfen der Atmosphäre zu übergeben.It has been described in the literature and in several patent applications that it is useful is, the flue gas from Possil power plants, which has been pre-cleaned by a desulphurisation system, in Initiate cooling towers and dampen with the cooling tower to surrender to the atmosphere.
Bei Trockenkühltürmen ist dieses Verfahren gut machbar, da Entschwefelungsanlagen in der Segel zwischen 80 % - 90 % wirksam das SOo aus dem zu reinigenden Rauchgas abscheiden und die letzten 10 % - 20 % mit dem Vervielfältigungsvolumen der in Thermik begriffenen Abgase des Kühlturms in einem Verhältnis von etwa 1 : 20 bis 1 : 30 gut durchmischt und gut verteilt werden, in die höheren Luftschichten aufsteigen und diffundiert werden.With dry cooling towers, this process is easily feasible, as desulphurisation systems in the sails separate 80 % - 90 % effectively the SOo from the flue gas to be cleaned and the last 10% - 20 % with the multiplication volume of the thermal exhaust gases of the cooling tower in a ratio of about 1:20 to 1:30 should be well mixed and well distributed, ascending into the higher layers of air and being diffused.
Die Mehrzahl aller Kühltürme sind jedoch Naßkühltürme und werden in absehbarer Zeit soweit wie möglich auch aufgrund der günstigeren Preisgestaltung Naßkühltürme bleiben.The majority of all cooling towers, however, are wet cooling towers and will be in the foreseeable future as much as possible due to the cheaper pricing Wet cooling towers remain.

Das Einleiten von teilentschwefelten Abgasen in Naßkühltürme ist jedoch problematisch.The introduction of partially desulphurized exhaust gases into wet cooling towers however, is problematic.
Der Restgehalt von SOp würde mit den nassen Kühlturmabdämpfen Schwefelsäure bilden, die verheerende Wirkungen bei der Kühlleistung durch Korrosin an den Maschinen verursachen.The residual SOp content would be steamed off with the wet cooling tower Form sulfuric acid, which has a devastating effect on the cooling capacity due to corrosin on the Machines cause.
Um dieses zu vermeiden und trotzdem Naßkühltürme verwenden zu können, in denen entschwefeltes Rauchgas direkt eingeführt wird oder in denen Rauchgasentschwefelungsanlagen integriert sind und somit das teilentschwefelte Gas in die Kühldampfmengen diffundieren, insbesondere im Bereich oberhalb der Wasserverteilung, wird erfindungsgemäß vorgeschlagen, in die rohrförmigen Einführungsstrecken der teilentschwefelten Rauchgase zur Neutralisation Ammoniak (NH^) einzublasen.To avoid this and still be able to use wet cooling towers in which desulphurized flue gas is introduced directly or in which flue gas desulphurisation systems are integrated and thus the partially desulphurized gas diffuses into the cooling steam, in particular in the area above the water distribution, it is proposed according to the invention, in the tubular Inlet sections of the partially desulphurized flue gases to neutralize ammonia (NH ^).
Durch diese erfindungsgemäße Verfahrenstechnik wird das SOp zu Ammoniumsulfit bzw. Ammoniumsulfat durch Aufoxidation gewandelt, und somit wirkt es in dem Bereich der nassen Rauchschwaden neutral, d. h. für die rückfließenden Tröpfchen durch Kondensation sogar noch positiv neutralisierend auf das Kühlwasser.This process technology according to the invention turns the SOp into ammonium sulfite or ammonium sulfate Oxidation converted, and thus it has a neutral effect in the area of the wet smoke plumes, i. H. for the returning droplets even through condensation still positively neutralizing on the cooling water.
