SOLAR DESALTER Russian patent published in 1995 - IPC

FIELD: solar-energy technology. SUBSTANCE: solar desalter has air outlet valve installed in the upper part of distillate collector and sun-tracking system including, at least, three cylinders with low-boiling liquid which are symmetrically located relative to concentrator symmetry axis on the upper part of central hollow of evaporating chamber. The cylinders are connected by means of pipelines with hollows of respective hydraulic cylinders corresponding to the number of cylinders secured on the side of their hollows on the nonworking surface of body for orientation of concentrator on supporting device by moving hydraulic cylinder rods rigidly connected to respective floating members, and adjusting valves which connect cylinders by pipelines. Selective coating is made in form of interference coating of two-layer system with high and low refractive indices transmitting infra-red region of solar spectrum or hot-pressed fluoride. EFFECT: higher efficiency. 2 cl, 1 dwg
