Abstract
The device (1) for bringing a gas and a liquid into contact includes an enclosure (E), first means (5) for introducing into the enclosure and circulating therein a gas stream (G), second means (6) for introducing into the enclosure and circulating therein a liquid stream (L) that circulates inside the enclosure (E) in the same direction as the gas stream (G), and means (4A) for mixing the gas stream (G) and the liquid stream (L). These mixing means (4A) are positioned inside the enclosure (E) in the path of the gas stream and liquid stream and are capable of locally deflecting upward, and/or of locally causing to rise, at least one portion of the gas stream and liquid stream, so as to locally create turbulences in the gas stream and in the liquid stream.

A device for bringing a gas and a liquid into contact comprising an enclosure, first means (5) for introducing into said enclosure and circulating therein a gas stream, second means (6) for introducing into said enclosure and circulating therein a liquid stream that circulates inside the enclosure in the same direction as the gas stream, and the enclosure comprising at least a first portion in which the gas stream and the liquid stream descend, the device further comprising mixing means for mixing the gas stream and the liquid stream, said mixing means comprising at least one mixing element, said at least one mixing element being positioned inside the first portion of the enclosure in a path of the gas stream and liquid stream, wherein said at least one mixing element has a concave curved upper surface whose curvature is adapted to locally deflect at least one portion of the descending gas stream and of the descending liquid stream upward, so as to locally create turbulence in the descending gas stream and in the descending liquid stream, wherein said at least one mixing element has a first edge and a opposite second edge and is fixed inside said first portion of the enclosure, wherein the second opposite edge is spaced from a side wall of the first portion of the enclosure to provide a space between said second edge and said side wall and to allow a downward passage of the descending gas stream and of the descending liquid stream and wherein the second edge is located at a level lower than the first edge but at a level higher than a lowest point of the curved upper surface of the at least one mixing element.
A device for bringing a gas and a liquid into contact comprising an enclosure, first means for introducing into said enclosure and circulating therein a gas stream, second means for introducing into said enclosure and circulating therein a liquid stream that circulates inside the enclosure in the same direction as the gas stream, and means for mixing the gas stream and the liquid stream, the means for mixing the gas stream and the liquid stream are positioned inside the enclosure in a path of the gas stream and liquid stream and the means for mixing the gas stream and the liquid stream comprise at least one rotary mixing member, which is adapted when it is rotated to locally deflect upward, at least one portion of the gas stream and the liquid stream, so as to locally create turbulences in the gas stream and in the liquid stream.
A device for bringing a gas and a liquid into contact comprising an enclosure, first means for introducing into said enclosure and circulating therein a gas stream, second means for introducing into said enclosure and circulating therein a liquid stream that circulates inside the enclosure in the same direction as the gas stream, and means for mixing the gas stream and the liquid stream, which are positioned inside the enclosure in the path of the gas stream and liquid stream and which are capable of locally deflecting upward, of locally causing to rise, or a combination thereof, at least one portion of the gas stream and liquid stream, so as to locally create turbulences in the gas stream and in the liquid stream, and wherein the enclosure comprises, downstream from the means for mixing the gas stream and the liquid stream, a horizontal portion inside which is fixed at least one lower vertical internal wall which comprises a free upper edge spaced apart from a wall of this horizontal portion of the enclosure, so as to provide, between the wall of the horizontal portion of the enclosure and said free upper edge, a passage for the gas and the liquid.
