Energiesparende Entsalzungsanlage / Siedetrennung BeschreibungEnergy-saving desalination plant / boiling separation Description
Das Problem der Süßwassergewinnung durch vorhandene Siedetrennungs- und Entsalzungsmethoden ist bis heute weltweit unzureichend gelöst. Das Manko all dieser Anlagen ist ihr sehr hoher Energieverbrauch.The problem of fresh water production using existing boiling separation and desalination methods has not yet been adequately solved worldwide. The disadvantage of all these systems is their very high energy consumption.
Der Erfindung liegt die Aufgabe zugrunde, eine solche technische Lösung einer Entsalzungsanlage vorzuschlagen, die gegenüber den bestehenden Anlagen bedeutend energiesparender und in ihrem Aufbau einfach ist und damit eine kostengünstige Massenproduktion ermöglicht.The invention is based on the object of proposing such a technical solution for a desalination plant which is significantly more energy-efficient than existing plants and is simple in its construction, thus enabling cost-effective mass production.
Die Aufgabe wird dadurch gelöst, daß die in der Verdampfungskammer 1 für die Verdampfung aufgebrachte Wärmeenergie durch die Verwendung eines wärmeisolierten (Vakuum in Rohr 9) und im Gegenlauf arbeitenden Wärmeaustauschers 16 größtenteils wiedergewonnen wird. Da trotzdem Wärmeverluste unvermeidlich sind, wird die zusätzliche Energie durch einen Sonnenkollektor (auf Fig. 1 nicht gezeigt) und/oder einen extern gespeisten elektrischen Erhitzer (auf Fig. 1 nicht gezeigt) gewonnen.The object is achieved in that the heat energy applied in the evaporation chamber 1 for the evaporation is largely recovered by using a heat-insulated (vacuum in pipe 9) and counter-current heat exchanger 16. Since heat losses are nevertheless unavoidable, the additional energy is obtained by a solar collector (not shown in Fig. 1) and/or an externally powered electric heater (not shown in Fig. 1).
Die Dampfsättigung hängt jeweils von der Art der Flüssigkeit, der Temperatur und dem Druck ab. Deshalb beinhaltet die hier vorgesehene technische Lösung eine sich gegenseitig bedingende Steuerung der Temperatur und des Druckes in der Verdampfungskammer 1. Für die Steigerung des Kondensationsprozesses im von der Dampf-Luftgemischpumpe 2 abgehenden Kondensationsrohr 5 ist außerdem eine steuerbare Druckerhöhung bezogen auf den Druck in der Verdampfungskammer vorgesehen. Diese Druckerhöhung wird durch das Zusammenwirken der Dampf-Luftgemischpumpe 2 und der Luftzuführpumpe 14 erreicht. Im Kondensationsrohr 5 erfolgt durch das Niederschlagen des Kondensats auf der Innenfläche des Rohres 5 die Trennung der Flüssigkeit von der Luft. Außerdem erfolgt hier eine permanente Wärmeübertragung durch die Rohrwand an das hinführende Rohr 10 Als Wärmeträger wird heiße, unter Überdruck (durch Pumpen 2 und 14) stehende Luft eingesetzt, die sich in einer Zirkulation von dem Trennbehälter 12 über dem Rohr 10, wo sie vorgewärmt wird, dann durch den Sonnenkollektor (auf Fig. 1 nicht gezeigt) und/oder elektrischen Lufterhitzer (auf Fig. 1 nicht gezeigt) bewegt. Die erhitzte Luft kommt in das Rohr 9, wo sie über Luftdüsen in das Salzwasserzuführrohr 8 eingeblasen wird. Die Luft in Form von Luftbläschen nimmt die Wasserdämpfe auf und transportiert sie in die Verdampfungskammer 1, die durch die Glaskappe 3 und das Vakuum 4 wärmeisolirt ist, gleichzeitig auf ihrem Weg im oberen Abschnitt des Rohres 8 wird das umgebene Salzwasser aufwärmt und außerdem über die Rohrkante befördert. DamitThe steam saturation depends on the type of liquid, the temperature and the pressure. Therefore, the technical solution provided here includes a mutually dependent control of the temperature and pressure in the evaporation chamber 1. To increase the condensation process in the condensation pipe 5 leading from the steam-air mixture pump 2, a controllable pressure increase based on the pressure in the evaporation chamber is also provided. This pressure increase is achieved by the interaction of the steam-air mixture pump 2 and the air supply pump 14. In the condensation pipe 5, the liquid is separated from the air by the condensate depositing on the inner surface of the pipe 5. In addition, there is a permanent heat transfer through the pipe wall to the incoming pipe 10. Hot air under excess pressure (by pumps 2 and 14) is used as the heat carrier, which circulates from the separating container 12 above the pipe 10, where it is preheated, then through the solar collector (not shown in Fig. 1) and/or electric air heater (not shown in Fig. 1). The heated air enters the pipe 9, where it is blown into the salt water supply pipe 8 via air nozzles. The air in the form of air bubbles absorbs the water vapor and transports it into the evaporation chamber 1, which is thermally insulated by the glass cap 3 and the vacuum 4. At the same time, on its way in the upper section of the pipe 8, the surrounding salt water is heated up and also transported over the edge of the pipe. This
wird eine ständige Salzwasserförderung und die Verhinderung der Salzablagerung erreicht.A constant supply of salt water and prevention of salt deposits are achieved.
Zusätzliche Verdampfung erfolgt von dem Salzwasserstandsniveau 6 des Salzwasserabfuhrrohr 17. Durch ständiges Nachfüllen aus dem Rohr 8 bewegt sich erwärmtes Salzwasser in das Salzwasserabfuhrrohr 17 herunter und erwärmt über die Rohrwand das im Gegenlauf steigende Salzwasser im Salzwasserzuführrohr 8.Additional evaporation occurs from the salt water level 6 of the salt water discharge pipe 17. By constantly refilling from the pipe 8, heated salt water moves down into the salt water discharge pipe 17 and heats the salt water rising in the opposite direction in the salt water supply pipe 8 via the pipe wall.
