Abstract A system for diaphragm distillation of a liquid, for example for desalination of salt water, comprising a diaphragm, through which vapour, but not liquid can pass, and a condensation surface for condensing vapour having passed through the diaphragm, and necessary passsageways. According to the invention, the system comprises one or several units, each of which comprises a plurality of pipes located one within the other, viz. a first (1) inner pipe, a second (2) pipe located outside thereof and consisting of a diaphragm of the aforesaid kind, and a third (3) pipe located outside the second (2) pipe, which first (1) and third (3) pipes are of a gas-tight material, that said unit is surrounded by a fourth (4) gas-tight pipe, where a first (5) passageway is formed by the first (1) pipe and a second (6), a third (7) and a fourth (8) passageway are formed between said pipes (1,2;2,3;3,4) in successive order in the direction from the inside outward. The said passageways (5,6,7,8) in radial order are intended to transport a warm medium (WW) for the supply of heat, to transport the liquid (SW) to be distilled, to condense gas having passed through the diaphragm (2) and to transport distillate (PW) which has been condensed, where the condensation of the gas takes place against a condensation surface, which consists of the passageway surface opposite to the diaphragm (2), and, respectively, to transport a cold medium (CW) for heat removal. Fig. 1 to be published.
