Abstract

A mechanical vapor recompression (MVR) liquid purification system, in particular an MVR water desalination system, comprising a pressure-tight enclosure (2) provided with a first end (4) and a second end (6), having an essentially circular cylindrical elongated shape along a longitudinal axis A, and numerous evaporation compartments E1-E3, arranged within said enclosure (2) along the longitudinal axis A. Each evaporation compartment is provided with a plurality of longitudinal pipes (10) running from one sidewall (8) to the other sidewall (8), and that the circular sidewalls are provided with openings for said plurality of pipes. The system further comprises a central tube (12) running along the longitudinal axis A of the enclosure (2) through the centers of said evaporation compartments E1-E3, and configured to allow steam to flow from the second end to the first end of the enclosure. The number of pipes (10) is preferably highest in the first evaporation compartment E1, then gradually fewer in the second E2 and third E3. The pipes are configured to allow steam to flow from the first end (4) to the second end (6) of the enclosure (2).
