SOLAR DESALINATION APPARATUS Russian patent published in 1997 - IPC

FIELD: solar-energy engineering, continuous-action solar water desalination equipment. SUBSTANCE: proposed apparatus comprises heat insulating casing having lower darkened panel and plurality of inclined intermediate panels 5 with condensate collectors. Panels are formed with flanged edges in form of trays and they are provided with drainage pipes extending between adjacent panels. Upper cut ends of drainage pipes are disposed in horizontal planes lying over surface of panels and below their flanged edges, while lower cut ends of drainage pipes lie below identical planes of low-lying panels. Salted water admission pipe connected to surface of upper intermediate panel and lower ends of pipes are formed with side outlet openings. Pipes of panels are communicated with collector, to which excess brine is discharged. Upper panel and intermediate panels are made transparent for solar radiation. Intermediate panels are made of heat conductive glass or of glass reinforced with heating elements. Structural arrangement of apparatus ensures optimum level of filling panels with salted water and discharge of excess brine. EFFECT: improved efficiency and reliability in operation; salinization of panels is ruled out; maximum utilization of solar radiation energy. 3 cl, 1 dwg
