1,265,719. Contact gases with liquids. E. H. CARLSSON. 27 Oct., 1969 [31 Oct., 1968], No. 52419/69. Heading B1R. In an apparatus for concentrating a liquid containing dissolved or suspended solid material the liquid is introduced at 21 onto a bed of spherical or polygonal filling bodies circulated within a vessel 9 by a screw-conveyor 18 so that the bodies wetted by the liquid pass downwardly in counter current to a stream of gas, e.g. air, introduced into the vessel 9 through holes 8 from a supply ring 7. Concentrated liquid or dry solid material is withdrawn through a grid 24. Filling bodies discharged at the upper end of the conveyor 18 are spread outwardly by an annular baffle. In another embodiment the filling bodies are wetted by the liquid before being passed upwardly through the screw-conveyor.
