Title
(EN) APPARATUS FOR SOLAR DISTILLATION AND SOLAR DISTILLATION PLANT
(FR) APPAREIL DE DISTILLATION SOLAIRE ET USINE DE DISTILLATION SOLAIRE
Abstract
(EN)
An apparatus (1) for solar distillation is disclosed comprising an evaporation room (2), said evaporation room (2) comprising a sole trough (10) for storing and distributing of primary water (11) provided to be processed on an evaporation surface (9) and a transparent cover (8). The transparent cover (8) is arranged for allowing solar emission passing through the transparent cover (8) onto the evaporation surface (9). Said apparatus (1) further comprising a condensation chamber (3). Said condensation chamber (3) comprising at least one condenser (13) provided for condensing of water vaporised due to solar emission, and comprising a distillate trough (15) for collecting and draining of water condensed after evaporation for collecting distillate. The condensation chamber (3) is located adjacent to the evaporation chamber (2) so that condensation chamber (3) and evaporation chamber (2) are partly separated from each other by a partition wall (4). A passage (5, 6) is provided upside and downside of the partition wall (4). The at least one condenser (13) is arranged in the condensation chamber (3). The evaporation chamber (2) having a height increasing from a closed end (7) towards a condensation chamber (3).

L'invention concerne un appareil (1) de distillation solaire comprenant une chambre d'évaporation (2), ladite chambre d'évaporation (2) comportant une goulotte unique (10) de stockage et de distribution d'eau primaire (11) qui doit être traitée sur une surface d'évaporation (9) et un couvercle transparent (8). Le couvercle transparent (8) est conçu pour laisser passer les rayons solaires jusqu'à la surface d'évaporation (9). Ledit appareil (1) comprend de plus une chambre de condensation (3). Ladite chambre de condensation (3) comprend au moins un condenseur (13) permettant de condenser l'eau vaporisée par les rayons solaires, et une goulotte de distillat (15) permettant de recueillir et de vidanger l'eau condensée après l'évaporation a fin de recueillir le distillat. La chambre de condensation (3) est adjacente à la chambre d'évaporation (2) de façon que la chambre de condensation (3) et la chambre d'évaporation (2) soient partiellement séparées par une cloison (4). Un passage (5, 6) est situé en haut et en bas de la cloison (4). Le ou les condenseurs (13) sont situés dans la chambre de condensation (3). La hauteur de la chambre d'évaporation (2) augmente d'une extrémité fermée (7) vers une chambre de condensation (3).
