Description
Solarer FlüssigkeitsverdampferSolar liquid evaporator
Solare Fliissigkeitsverdampfer sind seit langem bekannt für die Gewinnung von Süßwasser aus Salzwasser. Verbesserungsmöglichkeiten bestehen in Bezug auf'den Wirkungsgrad; vordringlich ist die Verbilligung entsprechender Anlagen sowie ihre technische Vereinfachung, da beides Voraussetzung für eine breite Anwendung in Entwicklungsländern ist.Solar liquid evaporators have long been known for extracting from fresh water from salt water. There is room for improvement in relation to the Efficiency; The most important thing is to make the corresponding facilities and theirs cheaper technical simplification, as both are prerequisites for widespread use in developing countries is.
Einen Fortschritt in diesem Sinne bedeutete die Verwendung von Kunststoff-Schläuchen, in denen die Verdampfung von Wasser sowie die Erwärmung der im Kreislauf geführten Luft erfolgt. Der Betrieb solcher Anlagen setzt jedoch eine sehr sorgfältige Gestaltung des Untergrundes unter dem Verdampferschlauch sowie eine genaue Dosierung des zugeführten Salzwassers Voraus, da sonst ihr Wirkungsgrad schnell abfällt. Dies gilt insbesondere in solchen Fällen, wo kein horizontales Gelände für die Auslegung des Verdampferschlauchs zur Verfügung steht.The use of plastic hoses was a step forward in this sense. in which the evaporation of water as well as the heating of the circulated Air takes place. However, the operation of such systems requires very careful design of the subsurface under the evaporator hose as well as an exact dosage of the supplied Salt water ahead, otherwise their efficiency drops quickly. This is especially true in those cases where there is no horizontal terrain for the layout of the evaporator hose is available.
Erfindungsgemäss wird ein entscheidender Fortschritt dadurch erreicht, dass die zugeführte Flüssigkeit (beispielsweise Salzwasser) nicht als mindestens mehrere Millimeter starke Schicht über der untersten, als Absorber dienenden schwarzen Kunststoff-Folie steht, sondern sich durch die Kapillaren eines Vlieses oder Gewirkes bewegt, das schwarz eingefärbt ist und als Absorber wirkt. Es bedeckt praktisch die ganze Grundfläche des Folienschlauchs und ist auf der untersten Folie aufgeklebt oder aufgeschweisst. Es kann auch auf eine Folie kaschiert sein, die auf die untere Schlauchfolie aufgelegt, geklebt oder geschweisst ist.According to the invention, a decisive advance is achieved by that the supplied liquid (e.g. salt water) is not considered to be at least several millimeters thick layer above the lowest black one that serves as an absorber Plastic film is available, but is spread through the capillaries of a fleece or knitted fabric moves, which is colored black and acts as an absorber. It practically covers the entire base of the film tube and is glued to the bottom film or welded on. It can also be laminated on a film that is on the lower one Tubular film is placed, glued or welded.
Die Flüssigkeit strömt innerhalb des Vlieses bzw. Gewirkes aufgrund der Wirkung der Schwerkraft bzw. der Kapillarwirkung. Oberhalb des Vlieses bzw.Gewirkes strömt Luft vorbei, die den gebildeten Wasserdampf in bekannter Weise aufnimmt und in einem Kondensor abgibt.The liquid flows within the fleece or knitted fabric the effect of gravity or the capillary effect. Above the fleece or knitted fabric air flows past, which absorbs the water vapor formed in a known manner and emits in a condenser.
Bei günstigen klimatologischen und Gelände-Bedingungen ergibt sich bei dem neuen Prinzip die Möglichkeit, ohne jede Hilfsenergie Wasser (oder eine andere Flüssig-WeiL) zu verdampfen und zu kondensieren. Dazu wird vor den Verdampferschlauch ein zweilagiger Folienschlauch als solarer Lufterhitzer geschaltet und nach dem Verdampferschlauch ein zweilagiger Kondensorschlauch, dessen Oberfolie weiss eingefärbt oder metallisch reflektierend ist. Um eine natürliche Luftströmung durch den Schlauch zu erzielen, wird der erste, zur Lufterhitzung dienende Teil in Richtung der Luftbewegung leicht ansteigend ausgelegt.Der nachfolgende Verdampferteil dagegen wird leicht abfallend ausgelegt, da die ihn durch strömende Luft mit ansteigender Feuchte spezifisch schwerer wird. Die Lage des Kondensatorteils ist von sekundärer Bedeutung, da in ihm Trocknung und gleichzeitige Abkühlung der Luft die änderung von deren Dichte weitgehend kompensieren. Natürliche Luftbewegung in der Umgebung kann für die Luftbewegung im Schlauch zusätzlich genutzt werden.With favorable climatological and terrain conditions results With the new principle, the possibility of using water (or a other liquid white) to evaporate and condense. This is done in front of the evaporator hose a two-layer film tube switched as a solar air heater and after the Evaporator hose is a two-layer condenser hose, the upper film of which is colored white or is metallic reflective. To get a natural flow of air through the hose To achieve this, the first part, which is used to heat the air, is in the direction of air movement designed with a slight incline Evaporator part on the other hand is designed to be slightly sloping, as the air flowing through it increases with it Moisture specifically becomes heavier. The location of the capacitor part is of secondary importance Meaning, because in it drying and simultaneous cooling of the air the change largely compensate for their density. Natural air movement in the area can also be used for air movement in the hose.
