| 摘要 |
The invention relates to a facility which comprises an evaporation device (1′), which comprises an evaporation chamber (10) intended for containing water (11) in liquid form and allowing only a portion of the water contained in the evaporation chamber (10) to be evaporated, and gas-supply means (12) for injecting a gas into the water (11) contained in the evaporation chamber (10), such as to form gas bubbles in said water, and a heat exchanger (3), which comprises cooling means (300, 310, 311/300, 301) and which allows at least the water vapour from the evaporation chamber (10) to be condensed. The facility comprises water-supply means (14), which make it possible to pump water in liquid form (L) in a natural environment, to send said water pumped in a natural environment through said cooling means (300, 310, 311/300, 301) or to bring said water into contact with said cooling means (300, 310, 311/300, 301), such as to allow the cooling of the water vapour from the evaporation chamber (10), and to supply the evaporation chamber (10) with said water after said water has been heated, having passed through or been brought into contact with said cooling means (300, 310, 311/300, 301). The evaporation chamber (10) comprises means (10c; 143) for discharging a portion of the water in liquid form (L) contained in the chamber which, in combination with the water-supply means (14), make it possible to renew the water inside the chamber such that the temperature of the water contained in the chamber (10) is kept at a temperature that is sufficient for maintaining the evaporation of a portion of the water contained in the evaporation chamber (10). |

1. A facility for treating water pumped in a natural environment by evaporation and condensation, said facility including an evaporation device (1′), which comprises an evaporation chamber (10) intended to contain water (11) in liquid form, and allowing only a portion of the water contained in the evaporation chamber (10) to be evaporated, and gas supply means (12) making it possible to inject a gas into the water (11) in liquid form contained in the evaporation chamber (10), so as to form gas bubbles in that water, and a heat exchanger (3/3′/3″), which includes cooling means (300, 310, 311/300, 301) and which makes it possible at least to condense the water vapor coming from the evaporation chamber (10), said facility comprising water supply means (14), which make it possible to pump water in liquid form (L) in a natural environment, and in particular seawater, lake water or water from a stream, or groundwater, to send said water in liquid form pumped in a natural environment through said cooling means (300, 310, 311/300, 301) or place it in contact with said cooling means (300, 310, 311/300, 301), so as to allow the cooling of the water vapor coming from the evaporation chamber (10), and to supply the evaporation chamber (10) with that water in liquid form (L) pumped in a natural environment after that water in liquid form (L) has been heated while having traversed or been placed in contact with said cooling means (300, 310, 311/300, 301), wherein the evaporation chamber (10) includes means (10c; 143) for discharging part of the water in liquid form (1) contained in the evaporation chamber (10) which, in combination with the water supply means (14), allow a renewal of the water in liquid form (L) inside the evaporation chamber (10), such that the temperature of the water in liquid form (L) contained in the chamber (10) is kept at a sufficient temperature to maintain the evaporation of part of the water contained in the evaporation chamber (10). |
