In a process for separating mixtures of matter in the liquid phase and a device suitable therefor, liquid (12) absorbs heat during its passage through a first cavity (3), said heat having been generated during the condensation yielding the condensate (13) at the upper wall portion (5) of the first cavity. The thus preheated liquid is passed to a third cavity (9), the upper wall portion (10) of which is liquid-tight and gas-tight and absorbs the thermal radiation (11). Part of the liquid further heated by said process evaporates and penetrates in vapor form through the liquid-tight, steam-permeable upper wall portion (8) of the third cavity (9) into a second cavity (6), the upper wall portion (8) of which is one and the same as the lower wall portion (9) of the third cavity. This steam condenses under the cooling action of the first cavity (3). The condensate (13) so formed is withdrawn from the second cavity. The cavities (1) and (3) are advantageously contained in double fabrics provided with adequate coatings and the two fabrics of which are spaced apart by means of spacers in the form of filaments. |
