MULTI-EFFECT DISTILLATION WATER DESALINATION SYSTEM WITH COLD SOURCE REUSE AND METHOD THEREOF

摘要

The main object of the invention is a water desalination system (1) by multi-effect distillation, comprising at least: a first effect (E1; E1 '; E1 ") of hot source inlet; a cold source inlet heat (Cn; Cn '; Cn "); central effects in series, each comprising a heat exchanger; a distribution circuit (D; D '; D ") of water to be desalinated; a fresh water outlet (ED; ED'; ED '') configured to recover the fresh water obtained, characterized in that at least a portion of the heated water (ER; ER '; ER' ') at the outlet of said at least one cold source inlet heat exchanger forms an additional cold source (SF'; SF '') supplying at least one heat exchanger additional heat (Cn '; Cn "), itself supplying water to desalt a plurality of effects to increase the production of fresh water.
