Abstract (en)
[origin: US2006272933A1] The inventive device is embodied in the form of a chamber-oven for diffusing vapour and saturated hot air which circulate in a closed circuit by natural convection. Said device is embodied in the form of a domestic-use solar energy collecting device provided with a greenhouse whose surface is equal to 1 m<SUP>2 </SUP>and produces from 50 to 100 litres/day of distilled water. The device comprises a distillation unit arranged between two furnaces ( 59', 79 ') in a temperature-controlled container ( 48 '). Said distillation unit comprises 100 flat thin hollow plates having a surface of 20 dm<SUP>2 </SUP>by face and an active volume of 200 dm<SUP>3</SUP>. The fine and tensioned walls ( 54 ) of said plates are provided with a hydrophilic coating ( 60 ') and internal ( 56 ') and inter-plate ( 58 ') spaces. The lower chimney ( 59 ') comprises a greenhouse ( 118', 119 ') whose bottom is embodied in the form of an impermeable black layer provided with a thin hydrophilic carpet on the rear part thereof. Saturated hot air at a temperature of 80° C. enters inside ( 56 ') hollow plates from bellow and exits from the top at a temperature of 50° C. A high chimney ( 79 ') is provided with a monoblock heat exchanger ( 84 ') which is transversed by a non-potable water to be distilled which, afterwards is spread warm (40° C.) over the hydrophilic coating ( 60 '). During passage through the heat exchanger ( 84 ) the air is cooled to 30° C. and moved down by gravity to the inter-plate spaces ( 58 ') and exits therefrom at a temperature of 78° C. The distilled water condensed in the plates and by the heat exchanger is collected and removed. Brine is received in the bottom of the inter-plate space and distributed along the thin hydrophilic carpet of the bottom ( 122 ') of the greenhouse. An air current passes along said hot carpet is heated and saturated and enters the plates. The brine liquor finally flows in an air-preheating tank ( 63 ') which is emptied each morning. The greenhouse can be substituted by a heating tube transversed by a heating fluid or associated with another steam-jet tube. The more powerful chamber-ovens can produce at least 200 m<SUP>3</SUP>/day of distilled water for collective consumption. Said invention can be used for salt removal from seawater, co-generating electricity and potable water and for producing food concentrates.
