Description
Wasserfördereinrichtung mit SonnenkollektorenWater pumping device with solar panels
Mit der Erfindung soll eine möglichst einfache Einrichtung zur Ausnutzung der Sonnenergie für Wasserförderung gelöst werden.The invention is intended to be as simple a device as possible for utilization the solar energy for water pumping can be solved.
Diese Aufgabe wird dadurch gelöst, daß mit einem Sonnen-Kollektor Dampf mit einem Druck von mehreren atü erzeugt wird, wobei dieser Dampf das Wasser aus einem Pumpbehãlter, der im Wasser (im Brunnen) getaucht ist auf eine höhere Ebene drückt.This object is achieved in that with a solar collector Steam with a pressure of several atmospheres is generated, this steam being the water from a pump container that is submerged in the water (in the well) to a higher one Level presses.
Die Realisierung erfolgt bisher mit wesentlich komplizierteren Einrichtungen. Im Betrieb sind Anlagen, die den mittels Sonnenergie erzeugten Dampf einer Turbine zuführen.The implementation has so far been carried out with much more complicated facilities. There are systems in operation that use solar energy to generate steam from a turbine respectively.
Die dadurch entstehende mechanische Energie dient entweder zum direkten oder indirekten Betrieb einer Pumpe, wobei bein indirekten Betrieb ein Generator und ein Elektromotor zwischengeschaltet ist.The resulting mechanical energy is used either for direct or indirect operation of a pump, with indirect operation a generator and an electric motor is interposed.
Die Einrichtung nach unserem Vorschlag hat den Vorteil, daß sie wesentlich einfacher ist. Sie besteht, die Ventile ausgenommen,nur aus statischen Teilen, wie Druckbehälter und Rohre.The arrangement according to our proposal has the advantage that it is essential is easier. With the exception of the valves, it consists only of static parts, such as Pressure vessels and pipes.
Der Betrieb und die Wartung einer solchen Anlage ist sehr einfach, was für viele Anwendungsfälle von wesentlicher Bedeutung ist.The operation and maintenance of such a system is very easy, which is essential for many use cases.
Beschreibung des Aufbaus und der Funktion der Einrichtung nach dieser Erfindung: (Schema siehe Bild Nr. 1).Description of the structure and function of the device according to this Invention: (scheme see picture no. 1).
Die Anlage besteht grundsätzlich aus: Sonnenkollektor 1, Dampfkessel 2, Pumpbehälter 3, Dampfrohr 4, Steigrohr 5 und Entlüftungsrohr 6..Zusätzlich kann noch ein Wasserbehälter 7 und ein FUllrohr 8 vorhanden sein.The system basically consists of: solar collector 1, steam boiler 2, pump tank 3, steam pipe 4, riser pipe 5 and vent pipe 6..Additionally, can a water tank 7 and a filling pipe 8 may still be present.
Für einen guten Wirkungsgrad ist ein hoher Dampfdruck und damit eine hohe Arbeitstemperatur erforderlich.For a good efficiency is a high vapor pressure and thus a high working temperature required.
Die Temperaturwerte von ca. 2000 C können mit konzentrierenden Kollektoren erreicht werden.The temperature values of approx. 2000 C can be achieved with concentrating collectors can be achieved.
Der ilärmeaustausch Kol len tor-Dampfkessel kann mit einem offenen, d. h. das Wasser im Dampfkessel dient auch zum Wärmetransport, oder in einem geschlossenen System erfolgen.The exchange of heat from the collector steam boiler can be carried out with an open, d. H. the water in the steam boiler is also used to transport heat, or in a closed one System.
Im geschlossenen System fließt in dem Kreis -Kollektor-Wärmetauscher kochsiedendes Ö1. Wenn der Dampfkessel 2 höherliegt als der Kollektor, dann kann ein natürlicher Umlauf des Wärmeträgers, ohne zusätzliche Pumpe, erreicht werden.In the closed system, the collector heat exchanger flows in the circuit boiling oil 1. If the steam boiler 2 is higher than the collector, then can a natural circulation of the heat transfer medium can be achieved without an additional pump.
Bei einem konzentrierenden Kollektor ist es erforderlich, daß die Sonnenstrahlung möglichst senkrecht einfällt.With a concentrating collector it is necessary that the Solar radiation is incident as vertically as possible.
Bei Kollektoren mit zylinderparabolischen Reflektoren gelten diese Forderungen im wesentlichen nur für eine Achse.These apply to collectors with cylindrical parabolic reflectors Requirements essentially only for one axis.
Werden solche Kollektoren in Nord-Süd-Richtung angeordnet sind erfolgt die Nachführung während des Tages zusammen mit dem Sonnenumlauf, bei Anordnung in West-Ost-Richtung reicht eine tägliche oder gar wöchentliche Nachführung entsprechend der Höhe der Sonnenlaufbahn aus.Such collectors are arranged in a north-south direction tracking during the day together with the sun's orbit, if arranged in In the west-east direction, a daily or even weekly update is sufficient the height of the sun's orbit.
Die wöchentliche Nach führung kann von Hand oder automatisch ausgeführt werden, bei Kollektoranordnung mit Nord-Süd-Richtung ist eine automatische Nachführung sinnvoll. Die Energie zur Bewegung des Kollektors gewinnt man mittels Sollarzellen mit nachgeschaltetem Elektromotor oder durch Ausnutzung des Dampfdruckes, wobei z. B. der tägliche Druckaufbau im Dampfkessel das Weiterschieben eines Zahnrades über eine Kolbenstange bewirkt.The weekly update can be carried out manually or automatically If the collector is arranged with north-south direction, automatic tracking is possible sensible. The energy for moving the collector is obtained from solar cells with a downstream electric motor or by utilizing the steam pressure, whereby z. B. the daily pressure build-up in the steam boiler the further pushing of a gear effected via a piston rod.
Die Kollektorwärme bringt das Wasser des Dampfkessels zum Sieden. Hat der Dampfdruck einen ausreichend hohen Wert erreicht, so öffnet das Ventil 41 und das System kann mit der Arbeit anfangen.The collector heat brings the water of the steam boiler to the boil. When the vapor pressure has reached a sufficiently high value, the valve 41 opens and the system can start working.
Der Pumpbehälter ist zuvor über das Ventil b mit Wasser vollgelaufen. In diesem Zustand ist das Ventil 42 über die Niveaus teuerung geöffnet. Der nun einströmende Dampf verdrängt das Wasser und drückt es über das Steigrohr 51 nach oben, wo es in dem Wasserbehälter 7 fließt.The pump container has previously filled with water via valve b. In this state, the valve 42 is open via the level control. The now Incoming steam displaces the water and presses it down via the riser pipe 51 above, where it flows in the water tank 7.
Bei einer bestimmten Lage der Schwimnplate 31 wird das Ventil 42 gesperrt. Der Wasserdampf expandiert adaiabatisch bis der Druckbehälter 3 leer ist und der Druck bis zu einem Restanteil abgebaut ist. Dieser Restanteil wird je nach Konzeption über das Steigrohr 5 abgebaut oder über ein zusätzliches Entlüftungsrohr 6 , wobei das niveaugesteuerte Ventil 61 die Steuerung übernimmt. D.h. das Ventil 61 wird geöffnet nach Entleerung und geschlossen nach Füllung des Pumpbehälters 3 . Für den Fall, daß Wasser im Steigrohr 5 verbleibt, verhindert das Rücklaufsperrventil 51 das Zurückfließen des Wassers in den Pumpbehälter 3 (hauptsächlich wichtig bei großen Förderhöhen).When the floating plate 31 is in a certain position, the valve 42 is blocked. The water vapor expands adaiabatically until the pressure vessel 3 is empty and the Pressure is reduced to a residual proportion. This remaining portion is depending on the conception dismantled via the riser pipe 5 or via an additional vent pipe 6, wherein the level-controlled valve 61 takes over the control. That is, the valve 61 is opened after emptying and closed after filling the pump container 3. For the non-return valve prevents the event that water remains in the riser pipe 5 51 the water flowing back into the pump container 3 (mainly important for large delivery heads).
Nachdem sich der Druck abgebaut hat, kann sich der Pumpfbehälter 3 wieder über das Einlaufventil 33 füllen.After the pressure has decreased, the pump container 3 Fill again via the inlet valve 33.
Erreicht der Wasserspiegel das obere Niveau, so öffnet das Ventil 42, der Dampf strömt ein und das Ventil 33 schließt sich durch den Überdruck.When the water level reaches the upper level, the valve opens 42, the steam flows in and the valve 33 closes due to the overpressure.
Der Purflpvorgang wiederholt sich.The purfling process is repeated.
Die Ventile 42 und 61 können auch als Dreiwegventil ausgelegt sein. Wird dieses Ventil 42/61 auf der oberen Ebene angeordnet, so kann das separate Entlüftungsrohr 61 entfallen.The valves 42 and 61 can also be designed as a three-way valve. If this valve 42/61 is arranged on the upper level, the separate vent pipe 61 are not applicable.
Zur Erhöhung des Wirkungsgrades soll die Schwimmplatte 31, der Innenraum des Behälters 3 und das Dampfrohr 4 wärmeisoliert sein.To increase the efficiency, the floating plate 31, the interior of the container 3 and the steam pipe 4 be thermally insulated.
Eine weitere Verbesserung des Wirkungsgrades wird durch Bildung eines Unterdruckes im geschlossenen Wasserbehälter 7 erzielt. Der Unterdruck entsteht bei der Kondensation des Darores, dcr nach dem En1eeren mit einem bestimmten Restdruck im Pumpbehälter 3 vorhanden und über das Lüftungsrohr 6 bzw. das Steigrohr 5 in den Tflasserbehälter 7 geleitet wurde.A further improvement in efficiency is made by forming a Underpressure in the closed water tank 7 achieved. The negative pressure is created during the condensation of the Darores, after emptying with a certain residual pressure present in the pump container 3 and via the ventilation pipe 6 or the riser pipe 5 in the water tank 7 was passed.
Die Kondensation wird durch den Kühler 72 beschleunigt, wobei ein Wärmeaustausch mit dem aufsteigenden Wasser erfolgt.The condensation is accelerated by the cooler 72, with a Heat exchange takes place with the rising water.
Die Nachfüllung mit Wasser kann z. B. jeden Tag erfolgen.The refill with water can, for. B. be done every day.
Hierzu ist zum automatischen ivachfüllen des Dampfkessels 2 das Füllrohr 8 angedeutet. über Nacht sinkt Mer Druck im Dampfkessel 2 bis zur Kondensation des Dampfes.Dadurch kann Wasser von einem äußeren Behälter nachfließen. Sobald ein ueberdruck im Kessel 2 durch die Wirkung des Sonnenkollektors 1 entsteht, schließt das Rücklaufsperrventil, der Arbeitsdruck wird aufgebaut und der Pumpvorgang für einen Tag kann beginnen.For this purpose, the filling pipe is used to automatically refill the steam boiler 2 8 indicated. The pressure in boiler 2 drops overnight until the condensation occurs This allows water to flow in from an outer container. As soon as an overpressure occurs in boiler 2 through the action of solar collector 1, the non-return valve closes, the working pressure is built up and the pumping process for one day can begin.
Für größere Förderhöhen ist auch kaskadenartige Anordnung der PumpSehälter 3 möglich. In dem Fall fördert ein Pumpbehälter das Wasser in einen Zwischenbehälter, woher das Wasser mit anderen Pumpbehältern weiter transportiert wird.The pump container is also arranged in a cascade-like arrangement for greater delivery heights 3 possible. In this case, a pump container conveys the water into an intermediate container, where the water is transported from with other pump containers.
Diese Pumpbehälter können vom gleichen Dampfkessel über ein gemeinsames Dampfrohr angespeistsein.These pump tanks can be shared by the same steam boiler Steam pipe.
Der Vorteil dieser Anordnung besteht darin, daß der notwendige Restdruck kleiner ist; dadurch wird der Wirkungsgrad besser.The advantage of this arrangement is that the necessary residual pressure is smaller; this improves the efficiency.
Die Ventile 42,61 können auch innerhalb des Pumpbehälters 3 angeordnet sein; dadurch können die Durchführungen im Pumpbehälter 3 gespart werden.The valves 42, 61 can also be arranged inside the pump container 3 be; as a result, the bushings in the pump container 3 can be saved.
