摘要： 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).
A turbine assembly (14) is arranged in relation to said first end (4) of the enclosure (2) and at least partly within said central tube (12), comprising a turbine provided with turbine vane members (16) structured to provide steam flow in an axial direction, i.e. along the longitudinal axis, within said central tube (12) from said second end (6) to said first end (4) of the enclosure (2). The turbine assembly (14) comprises a motor (20) for rotating said turbine at a variable rotational speed.-

摘要： An energy system (1) arranged to generate and to use thermal energy is described. The energy system (1) comprises a mechanical vapor recompression (MVR) unit (3). Thermal energy of a working liquid is obtained during an MVR process performed by said MVR-unit (3) and is utilized externally outside of said energy system, preferably for heating processes, spaces, or objects. Preferably, the MVR unit comprises a primary heat exchanger (5), a compressor (9), a primary vapor line (11) and a condenser (13). The MVR-unit (3) preferably also comprises at least one liquid line (15) arranged in connection to the condenser (13) and to the primary heat exchanger (5) for transport of the condensed working liquid back to the primary heat exchanger (5) for re-evaporation in the primary heat exchanger (5). The energy system (1), in one embodiment, comprises at least one secondary heat exchanger (17) arranged for heat exchange between the condensed working liquid flowing in the at least one liquid line (15) and an external working fluid flowing in at least one external fluid line (19) to use thermal energy generated by the MVR-unit (3).
