Abstract
A foam scrubber for removing contaminants from gas comprising first means for entrapping small, discrete volumes of said gas within liquid film enclosures comprising a mass of foam bubbles. Means for maintaining said foam bubbles a selected maximum size and for a selected interval of soaking time permitting the contaminants within the bubbles to diffuse and become entrapped within the surrounding liquid film of the bubbles. Means for collapsing the foam bubbles after the soaking period and separating the contaminant containing liquid thereof from the cleansed gas.
Claims9
Apparatus for removing contaminants from a flowing gas stream comprising foam generator means for entrapping small discrete volumes of said gas within liquid film enclosures forming a mass of foam bubbles, said foam generator means including perforated means for supporting a film of liquid foaming material and forming said film into discrete bubbles filled with said gas moving through the perforations therein, said perforated means comprising a perforated member having formed pleats therein arranged with surfaces angularly intersecting said moving gas flow;
- sizing means for successively reforming said bubbles into smaller bubbles for maintaining a stable mass of small bubbles;
- soak chamber means for containing said mass of foam bubbles for movement away from said sizing means during a substantial soaking period ofor diffusion and collection of contaminants from said gas into said liquid film of the bubble walls;
- and foam breaker means receiving bubbles from said mass in soak chamber means for collapsing said foam bubbles to separate cleansed gas and contaminated liquid of said bubble walls.
