Abstract
Die Erfindung bezieht sich auf eine Anlage zur Entsalzung von Wasser z. B. aus unterirdischen Lagerstätten mit einem hohen Anteil an gelösten Salzen oder von Meerwasser unter Ausnutzung der Sonneneinstrahlung dadurch gekennzeichnet dass die Sole (5) innerhalb eines dicht an den Boden (6) angeschlossenen, vorzugsweise halbrunden Tunnels (1) in einer flachen Verdunstungsrinne (4) durch die tagsüber auftretende Sonneneinstrahlung erwärmt wird und somit das Wasser aus dieser Sole (5) zur Verdunstung gebracht wird, weiter dadurch gekennzeichnet, dass der Boden (6) unterhalb dieser Abdeckung nur teilweise von der Verdunstungsrinne (4) abgedeckt wird, weiter dadurch gekennzeichnet, dass der freibleibende Teil des Bodens (6) aus einer Masse besteht, welche die Fähigkeit besitzt, Feuchtigkeit zu speichern und wieder abzugeben, weiter dadurch gekennzeichnet, dass der Anschluss (1a) der transparenten Abdeckung an den Boden (6) zumindest teilweise durch eine Sammelrinne (2) gebildet wird, in der sich das während der Nacht an der nun kühlen Abdeckung (1b) bildende Destillat (3) sammeln kann.The invention relates to a system for the desalination of water z. B. from underground storage facilities with a high proportion of dissolved salts or from sea water using solar radiation, characterized in that the brine (5) within a preferably semicircular tunnel (1) connected closely to the ground (6) in a shallow evaporation channel (4 ) is heated by the daytime solar radiation and thus the water from this brine (5) is brought to evaporation, further characterized in that the bottom (6) below this cover is only partially covered by the evaporation channel (4), further characterized that the remaining part of the base (6) consists of a mass which has the ability to store moisture and release it again, further characterized in that the connection (1a) of the transparent cover to the base (6) at least partially by a Collecting channel (2) is formed, in which the dest illat (3) can collect.
Description
Stand der TechnikState of the art
Es sind Anlagen bekannt, die mittels Sonnenstrahlung salzhaltiges Wasser unter einer Folie bzw. unter Glas verdunsten und die so entstehende Luftfeuchtigkeit an einer gekühlten Innenfläche kondensieren und von dort in ein Sammelsystem ableiten.Systems are known which evaporate salt-containing water by means of solar radiation under a film or under glass and condense the resulting moisture on a cooled inner surface and from there into a collecting system.
Kritik am Stand der TechnikCriticism of the state of the art
Diese Anlagen dienen ausschließlich der Entsalzung von Meer- oder Brackwasser bzw. der Gewinnung von destilliertem Wasser aus Abwasser. Ferner funktionieren diese Anlagen nur dann, wenn die Temperatur der Kondensationsfläche den Taupunkt unterschritten hat, also entweder nur nachts oder mittels aktiver Kühlung und z. T. aufwändiger Technik. Auch sind Kleinanlagen bzw. mobile Anlagen bekannt, die mittels transparenter Abdeckungen in einer Schale oder in einem Behälter eingebrachtes Salzwasser verdunsten und in einer am unteren Rand der Abdeckung entlang laufenden Rinne sammeln. Auch geht durch die ausschließlich transparenten Abdeckungen, die aus dem Gewächshausbau und dem damit verbundenen Bedarf an Sonnenlicht herrühren, sehr viel Sonneneinstrahlung wieder verloren.These plants are used exclusively for the desalination of seawater or brackish water or the recovery of distilled water from wastewater. Furthermore, these systems only work if the temperature of the condensation surface has fallen below the dew point, ie either only at night or by means of active cooling and z. T. elaborate technology. Small plants or mobile plants are also known, which evaporate by means of transparent covers in a shell or in a container introduced salt water and collect in a running along the bottom of the cover along the gutter. Also goes through the exclusively transparent covers, which stem from the greenhouse and the associated need for sunlight, lost a lot of sunlight again.
Aufgabenstellungtask
Es ist die Aufgabe der Erfindung, Anlagen zur Entsalzung von Wasser bereitzustellen, mit denen es möglich ist, in der Hauptsache nur durch Sonnenenergie so großem Maßstab sowohl Trinkwasser herzustellen wie auch gleichzeitig ohne großen zusätzlichen technischen Aufwand Pflanzbereiche so zu bewässern, dass dadurch besonders im Landesinneren wasserarmer Länder oder in abgelegenen Wüstenregionen die notwendige Infrastruktur geschaffen wird, um dort einerseits Lebensraum für Mensch und Tier zu erhalten bzw. zu schaffen. Weiter liegt der Erfindung die Aufgabe zugrunde, in diesen jetzt vegetationslosen Regionen soviel Biomasse zu erzeugen, dass sich durch die damit verbundene CO2-Bindung und die erhöhte Umwandlung von Sonnenenergie in Biomasse ein positiver Effekt gegen den Klimawandel ergibt. Als wichtige ökosoziale Auswirkung kann eine erhebliche Verbesserung der Lebensbedingungen in diesen Regionen dazu beitragen, Hunger zu mildern, Arbeitsplätze zu schaffen und soziale Gegensätze und Spannungen abzubauen. Auch durch die Gewinnung von hochwertigem Meersalz oder anderen Rückstandsprodukten der Verdunstung sollen wirtschaftliche Gewinne erzielt werden.It is the object of the invention to provide plants for the desalination of water, with which it is possible to produce drinking water as large scale in the main only by solar energy as well as at the same time irrigate without much additional technical effort plant areas so that thereby particularly in the interior in water-scarce countries or in remote desert regions, the necessary infrastructure is created, on the one hand, to preserve or create living space for humans and animals. It is a further object of the invention to generate so much biomass in these now vegetationless regions that a positive effect against climate change results from the associated CO2 binding and the increased conversion of solar energy into biomass. As a major eco-social impact, significant improvements in living conditions in these regions can alleviate hunger, create jobs, and reduce social conflict and tensions. Also by the extraction of high quality sea salt or other residue products of the evaporation economic profits are to be achieved.
