Abstract
The present invention relates to an improvement for use in a device where a liquid floating on top of another liquid is to be drained to another part of the device, and where these are to be intimately mixed with each other in the form of a vortexinducing structure comprising at least one curved vane located above the exit port of the liquid, the vane extending substantially to the upper level of the liquid system, a lateral inlet being provided along a larger part of the vane structure. Preferably the device comprises a helical vane extending to the top level of the upper liquid, positioned above the outlet port. The invention further relates to an absorption machine of the lithium halide/water (lithium bromide and/or lithium chloride) type, equipped with at least one vortex inducing structure defined above and to a method of thoroughly mixing a lithium halide solution with 2-ethyl-n-hexanol used as additive, which comprises equipping an exit port of a compartment of an absorption machine of this type with a device defined above and draining the lithium halide/additive system through the exit port and circulating it to another part of the machine.
