Verfahren zum Reinigen von wasserdampfhaltigen Abgasen
Die Erfindung betrifft ein Verfahren zum Reinigen von wasserdampfhaltigen Abgasen zur Bekämpfung der Rauchplage.
Es wurde bereits vorgeschlagen, die Staubteilchen unter gleichzeitiger Wärmeabgabe an ein Kühlmittel auszuschleudern. Dieser Vorschlag setzt eine bestimmte Mindestgrösse der Staubteilchen voraus, weil sonst ihre Masse zu gering für das Auftreten eines Schleudereffektes wäre.
Demgegenüber lässt sich die Erfindung auch dann anwenden, wenn die Abgase so kleine Staubteilchen enthalten, dass deren Ausscheidung mit den bisher bekannten Verfahren und Vorrichtungen nicht möglich war. Es wird dies dadurch erreicht, dass die Abgase vor ihrem Austritt ins Freie einem Unterkühlungssystem zugeführt werden, in welchem der Wasserdampf in Form von Eiskristallen ausfällt, wobei die Schwebeteilchen der Abgase von den Eiskristallen umschlossen und/oder in deren Fallstrom mitgerissen werden. In jenen Fällen, in denen in den Abgasen Wasserdampf nicht in genügendem Ausmass oder überhaupt nicht enthalten ist, wird die erforderliche Menge Wasserdampf in die Abgase vor deren Eintritt in das Unterkühlungssystem eingeblasen. Dazu können an sich bekannte Berieselungseinrichtungen dienen.
Wenn die Abgase giftige Stoffe enthalten, dann kann man bei Zufuhr vort Wasserdampf diesen gasförmige Stoffe zufügen, die diese giftigen Stoffe in unschädliche Verbindungen überführen.
Das erfindungsgemässe Verfahren lässt sich mit allen hiezu geeigneten Vorrichtungen durchführen.
PATENTANSPRÜCHE :
1. Verfahren zum Reinigen von wasserdampfhaltigen Abgasen, dadurch gekennzeichnet, dass die Abgase, denen im Falle ungenügenden eigenen Wassergehaltes Wasserdampf zugeführt wurde, vor ihrem Austritt ins Freie einem Unterkühlungssystem zugeführt werden, in dem der Wasserdampf in Form von Eiskristallen ausfällt, wobei die Schwebeteilchen der Abgase von den Eiskristallen umschlossen und/oder in deren Fallstrom mitgerissen werden.

Process for cleaning exhaust gases containing water vapor
The invention relates to a method for cleaning exhaust gases containing water vapor in order to combat the plague of smoke.
It has already been proposed to eject the dust particles while at the same time giving off heat to a coolant. This proposal presupposes a certain minimum size of the dust particles, because otherwise their mass would be too small for a centrifugal effect to occur.
In contrast, the invention can also be used when the exhaust gases contain dust particles that are so small that it was not possible to separate them with the previously known methods and devices. This is achieved in that the exhaust gases are fed to a supercooling system before they exit into the open air, in which the water vapor precipitates in the form of ice crystals, the suspended particles of the exhaust gases being enclosed by the ice crystals and / or carried along in their downflow. In those cases in which the exhaust gases do not contain enough water vapor or not at all, the required amount of water vapor is blown into the exhaust gases before they enter the supercooling system. Irrigation devices known per se can be used for this purpose.
If the exhaust gases contain poisonous substances, then one can add gaseous substances, which convert these poisonous substances into harmless compounds, if the water vapor is supplied.
The method according to the invention can be carried out with all devices suitable for this purpose.
PATENT CLAIMS:
1. A method for cleaning exhaust gases containing water vapor, characterized in that the exhaust gases, to which water vapor was supplied in the event of insufficient water content of their own, are fed to a supercooling system before they exit into the open air, in which the water vapor precipitates in the form of ice crystals, the suspended particles of the Exhaust gases are enclosed by the ice crystals and / or carried away in their downdraft.
