| 摘要 |
The invention relates to a sea-water desanilation facility using multiple effect distillation (MED) with mechanical and thermal vapour compression (MTVC), which facility is intended to be coupled to a thermal power plant and includes (A) a series of distillation cells (stages A, B, C, D, E), each operating at a temperature and at a pressure lower than the preceding stage, and (B) a vapour compression means for compressing the water vapour emitted by the last stage and reinjecting same in the first stage, wherein the vapour compression means consists of a parallel-mounted, alternately operating thermocompressor (6) and mechanical compressor (9) and said facility further includes (a) a heat discharge means (8) and first (11) and second (10) heat recovery means. A sea-water desalination method using such a facility is also described. |
