Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Verbesserung der Wasserqualität von Wasser in Fischtransport behältern.The invention relates to a method and an apparatus for Improving the water quality of water in fish transport containers.
Fische atmen, wie fast alle Lebewesen, Sauerstoff ein und Kohlensäure aus. Befinden sich zu viele Fische über einen längeren Zeitraum in einem Fischtransportbehälter, dann besteht die Gefahr, daß die Fische die Kohlensäure, die sie ausatmen müssen, nicht mehr an das Transportwasser abgeben können. Das Wasser ist mit der ausgeatmeten Kohlensäure so gesättigt, daß es nichts mehr aufnehmen kann. Die Folge davon ist, daß die Fische zu Grunde gehen.Like almost all living things, fish breathe in oxygen and Carbonic acid. There are too many fish over one longer period in a fish transport container, then there is a risk that the fish will carbonate them have to exhale, no longer give up to the transport water can. The water is like this with the exhaled carbonic acid saturated that it can no longer absorb anything. The consequence of this is that the fish perish.
Aus des DE-OS 30 07 783 ist es auch bekannt, das Wasser aus Fischtransportbehältern abzuziehen, dann einer Begasungseinrichtung zuzuführen und schließlich das Wasser zurück zum Fischtransportbehälter zu leiten. Dabei erfolgt aber nur eine unzureichende Verbesserung des Sauerstoffgehaltes, da der CO2-Anteil nicht wesentlich verringert wird.From DE-OS 30 07 783 it is also known that the water from fish transport containers subtract, then feed to a fumigation facility and finally the water back to the fish transport container conduct. However, there is only an inadequate one Improve the oxygen content since the CO2 content is not is significantly reduced.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Verbesserung der Wasserqualität von Wasser in Fischtransportbehältern zu schaffen, bei dem der CO2-Anteil möglichst vollständig entfernt wird. The invention is therefore based on the object of a method to improve the water quality of water in To create fish transport containers in which the CO2 content is removed as completely as possible.
Das wird dadurch erreicht, daß das Transportwasser einem Unterdruckbehälter zugeführt wird, worauf das so entgaste Wasser in einen Druckbehälter eingeleitet wird, dem Sauerstoff zugeführt wird.This is achieved in that the transport water one Vacuum tank is supplied, whereupon the degassed Water is introduced into a pressure vessel, the Oxygen is supplied.
Das bedeutet, daß mit Hilfe des Unterdruckbehälters das mit CO2 angereicherte Transportwasser entgast wird, so daß praktisch CO2-freies Transportwasser dem Druckbehälter zugeführt wird, in dem eine Anreicherung mit Sauerstoff erfolgt.That means that with the help of the vacuum tank CO2-enriched transport water is degassed so that practically CO2-free transport water to the pressure vessel is supplied in which an enrichment with oxygen he follows.
Damit eine möglichst gute Entgasung des mit CO2 angereicherten Transportwassers erfolgt, wird das dem Unterdruckbehälter zugeführte Transportwasser im Behälter versprüht.So that the best possible degassing with CO2 enriched transport water takes place, that is the Vacuum tank supplied transport water in the tank sprayed.
Auch das dem Druckbehälter zugeführte Wasser wird versprüht, um eine möglichst große Oberfläche für die Aufnahme von Sauerstoff zu erhalten.The water supplied to the pressure tank is also sprayed, to have as large a surface as possible for the reception of To get oxygen.
Die Vorrichtung zur Durchführung des Verfahrens ist gekennzeichnet durch einen mit Steigrohr versehenen Unterdruckbehälter, dessen oberer Bereich mit der Saugseite einer Unterdruckpumpe verbunden ist, und durch einen Druckbehälter, der über eine Leitung und eine Pumpe mit dem Unterdruckbehälter verbunden ist, wobei im Druckbehälter ein Steigrohr für die Zufuhr des entgasten Transportwassers angeordnet ist, und wobei ein Zufuhrrohr für die Sauerstoffzufuhr vorgesehen ist. The device for performing the method is characterized by a pipe with a riser Vacuum tank, the upper area with the suction side a vacuum pump is connected, and by one Pressure vessel, which is connected via a line and a pump to the Vacuum tank is connected, being in the pressure tank Riser pipe for the supply of the degassed transport water is arranged, and wherein a feed pipe for the Oxygenation is provided.
Damit eine möglichst gute Versprühung erfolgen kann, weisen die Steigrohre sowohl des Druckbehälters als auch des Unterdruckbehälters im oberen Bereich düsenförmige Öffnungen auf.So that the best possible spraying can take place, show the risers of both the pressure vessel and the Vacuum tank in the upper area nozzle-shaped openings on.
In der Zeichnung ist eine beispielsweise Ausführungsform dargestellt.In the drawing is an example embodiment shown.
Mit 1 ist der Transportbehälter bezeichnet, in dem das Transportwasser für die Fische enthalten ist. Über eine im oberen Bereich des Transportbehälters angeschlossene Leitung 2 wird das Transportwasser einem Unterdruckbehälter 3 zugeführt, in dem das Steigrohr 4 angeordnet ist. Das Transportwasser gelangt dabei in das Steigrohr 4 und wird im oberen Bereich mit Hilfe von Düsen 5 versprüht. Gleichzeitig ist der Unterdruckbehälter im oberen Bereich mit der Saugseite 6 einer Pumpe 7 verbunden. Mit Hilfe dieser Unterdruckpumpe wird das beim Versprühen des Transportwassers freiwerdende CO2 abgesaugt.With 1 the transport container is designated, in which the transport water for the fish is contained. Via a line 2 connected in the upper region of the transport container, the transport water is fed to a vacuum container 3 , in which the riser pipe 4 is arranged. The transport water gets into the riser pipe 4 and is sprayed in the upper area with the help of nozzles 5 . At the same time, the vacuum container is connected in the upper region to the suction side 6 of a pump 7 . With the help of this vacuum pump, the CO2 released when the transport water is sprayed is extracted.
Das so CO2-freie Transportwasser wird über eine Leitung 8 zunächst einer Pumpe 9 und dann mittels einer Leitung 10 dem Steigrohr 11 zugeführt, das in dem Druckbehälter 12 angeordnet ist. Auch das Steigrohr 11 besitzt im oberen Bereich Düsen 5, so daß eine möglichst gute Versprühung zum Zwecke der Erzielung einer möglichst großen Oberfläche erreicht wird. Über eine Leitung 13 wird Sauerstoff zugeführt, so daß sich das versprühte Wasser mit Sauerstoff anreichert, das dann über die Leitung 14 dem Transportbehälter wieder zugeführt wird. The CO2-free transport water in this way is first fed to a pump 9 via a line 8 and then to the riser pipe 11 via a line 10 , which is arranged in the pressure vessel 12 . The riser pipe 11 also has nozzles 5 in the upper region, so that the best possible spraying is achieved for the purpose of achieving the largest possible surface area. Oxygen is supplied via a line 13 , so that the sprayed water is enriched with oxygen, which is then returned to the transport container via line 14 .
Mit 15 ist ein Schwimmschalter bezeichnet, der entsprechend der Wasserhöhe im Unterdruckbehälter die Pumpe 7 ein- bzw. ausschaltet. 15 denotes a float switch which switches the pump 7 on or off in accordance with the water level in the vacuum container.
