Abstract

A two-stage gas scrubber has the two stages mounted on top of a common fluid sump. The fluid is circulated from the sump in two separate branches to an acid and an alkaline injection station. The latter branch also includes a dust absorption mat where dust and other contaminants are flushed off. A droplet separator is included upstream of the exhaust fan. The gas scrubber is simple and inexpensive, and removes contaminants requiring both acid and alkaline treatment.

"2-Stuten-Gaswäscher" Zur Waschung von Schadstoffen aus Abgasen, die mit unterschiedlichen Schadstoffen belastet sind, die sich a) partiell nur im sauren Bereich oder b) im alkalischen Bereich auswaschen lassen, ist es erforderlich, 2-Stufen-Waschanlagen zu verwenden."2-mare gas scrubber" For scrubbing pollutants from exhaust gases are contaminated with different pollutants, which a) partially only in the acidic Area or b) wash out in the alkaline area, it is necessary to use 2-stage washing systems to use.

Um diese ?-Stufen-Waschtechnik in sehr einfacher und preiswerter Bauweise zu gestalten, wird erfindungsgemäß eine Bauweise entsprechend beiliegender Zeichnunq vorgeschlagen.About this? -Step washing technology in a very simple and inexpensive design to design, according to the invention, a construction according to the accompanying drawing suggested.

In der beiliegenden Zeichnung ist dargestellt: mit 1) die erste Waschstufe, die z. B. im sauren Waschflussigkeitsbereich betrieben wird; mit 2) die zweite Waschstufe, die z. B. im alkalischen Waschbereich betrieben wird; mit 3) eine Staub- und Absorptionsmatte, die im Gas befindliche Stäube aus dem Gasstrom abscheidet und mit Wasser bespühlt wird, wobei gleichzeitig nicht nur die Staubbelastung aus dem vorgereinigten Gas abgeschieden wird, sondern auch gleichzeitig die Restschadstoffe; mit 4) der für beide Waschstufen zuständige Flüssigkeitssumpf; mit 5) die Pumpenstation, die für die erste und zweite Waschstufe zuständig ist und gleichzeitig eine Teilwassermenge der Neutralisation (11) zuführen kann.The accompanying drawing shows: with 1) the first washing stage, the z. B. is operated in the acidic washing liquid range; with 2) the second washing stage, the z. B. is operated in the alkaline washing area; with 3) a dust and absorption mat, separates the dust in the gas from the gas stream and rinsed it with water at the same time not only the dust pollution from the pre-cleaned gas is deposited, but also the residual pollutants at the same time; with 4) the liquid sump responsible for both washing stages; with 5) the pump station, which is responsible for the first and second washing stage and at the same time a partial amount of water can supply the neutralization (11).

mit 6) z. B. eine aure Impfstation, mit 7) z. B. die alkalische Impfstation, mit 8) ein ph-Wert-Meßgerät, mit 9) der Ventilator, nit 40) ein Tropfenabscheider.with 6) z. B. an aure vaccination station, with 7) z. B. the alkaline vaccination station, with 8) a ph-value measuring device, with 9) the fan, with 40) a droplet separator.
