Abstract An apparatus for putting a gas into contact with a liquid, especially for separating solid or liquid particles in suspension in said gas or for eliminating certain gaseous constituents, said apparatus comprising a space in the form of a diffuser adapted to effect intimate mixing of the gas and liquid by means of the formation of a turbulent and dense suspension of drops forming a kind of semi-stationary fluidized bed. The gas and liquid pass together into the bottom of the diffuser which has the form of a divergent conduit in which is created a closed circulation of liquid effecting a continuous renewal of the bed, the impurities of the gas being treated during this circulation by physical collection with or without chemical reaction, followed by a centrifugal action which separates the gas from the drops of liquid, the liquid thus recovered being wholly or partly recycled.
Gas-liquid contact apparatus comprising a closed housing having a lower portion providing a container for liquid, means for supplying liquid to said container portion, means for introducing gas to be contacted with liquid above and in contact with the surface of liquid in said container portion, a pair of upright planar upwardly diverging walls defining between them a narrow vertical mixing compartment in said housing and having a lower inlet end disposed above said surface of liquid, one of said walls being a side wall of said housing and the other of said walls being spaced from said one wall within said housing, and means for conveying gas from the upper end of said compartment, said walls cooperating with gas rising in said compartment to create in said compartment a substantially stationary but internally circulating vertical contact zone for prolonging contact between the liquid droplets and gas, said compartment having at least one transverse vertical partition therein extending between said walls and dividing said compartment into a plurality of sections.
