Abstract
Description
Um eine gesundheitlich unbedenkliche Wasserversorgung der Bevölke rung zu gewährleisten, wird von Seiten der Wasserwerke häufig mit Chlorgas gearbeitet. Die Zugabe von Chlorgas zum Trinkwasser garan tiert einen keimfreien Transport des Trinkwassers zum Verbraucher.A safe water supply for the people Ensuring this is often done by the waterworks Chlorine gas worked. The addition of chlorine gas to the drinking water guarantees germ-free transport of drinking water to the consumer.
Ein genaues bzw. nicht überhöhtes Anreichern mit Chlor gelingt nicht oft. Häufig wird gerade in Entwicklungsländern wegen defekter Versor gungsleitungen stark überchlort.Accurate or not excessive enrichment with chlorine is not possible often. It is common in developing countries because of defective supply supply lines heavily over-chlorinated.
Das unter Druck in großen Mengen gelöste Chlor wird beim Verlassen der Druckleitung aus der Flüssigkeit teilweise freigesetzt. Das Ergebnis ist ein milchig erscheinendes Trinkwasser, welches sich erst nach eini gen Minuten durch Aufsteigen der kleinen Chlorgasbläschen reinigt.The chlorine dissolved in large quantities under pressure is exited the pressure line is partially released from the liquid. The result is a milky-looking drinking water that only settles in after minutes by rising the small bubbles of chlorine gas.
Das ist nicht nur optisch unschön, es führt auch zu einem unangeneh men Geruch des Trinkwassers. Nicht zuletzt ist Chlorgas giftig. Wün schenswert von Seiten des Verbrauchers wäre die Versorgung mit keimfreiem Trinkwasser, das ohne Trübung, völlig geruchsneutral und frei von allen (Ammoniak, Chlor, CO2 etc.) Gasen ist.This is not only visually unattractive, it also leads to an unpleasant one men smell of drinking water. Last but not least, chlorine gas is toxic. Wu it would be worthwhile for the consumer to supply with germ-free drinking water that is completely turbid and odorless is free of all gases (ammonia, chlorine, CO2, etc.).
Dies kann durch die im folgenden beschriebene Vorrichtung gewährlei stet werden. This can be ensured by the device described below be steady.
Nach Anlieferung des Trinkwassers über die vorhandenen Druckleitun gen zum Haus des Verbrauchers wird die Freisetzung und Abtrennung des Chlorgases dadurch erreicht, indem das unter Druck stehende Trinkwasser vor der Entnahme durch einen Behälter (1) fließt, worin es mit Ultraschall behandelt wird. Die Methode der Flüssigkeitsentgasung in offenen Behältern mit Ultraschall ist hinlänglich bekannt. Die vorge stellte Anlage hingegen ist geschlossen und arbeitet unter üblichem Leitungsdruck.After delivery of the drinking water via the existing pressure lines to the house of the consumer, the release and separation of the chlorine gas is achieved by the pressurized drinking water flowing through a container ( 1 ) before it is drawn off, in which it is treated with ultrasound. The method of liquid degassing in open containers with ultrasound is well known. The system presented, however, is closed and works under normal line pressure.
Der Ultraschall erzeugt Sog und Druckimpulse welche auf das fließende Trinkwasser wirken. Die auftretende Kavitation bewirkt eine Freisetzung von gasförmigen gelösten Stoffen aus dem Wasser. Die Einwirkung von Ultraschall erniedrigt die Löslichkeit von Gasen in Flüssigkeiten.The ultrasound creates suction and pressure impulses which are flowing Drinking water work. The cavitation that occurs causes a release of gaseous solutes from the water. The action of Ultrasound lowers the solubility of gases in liquids.
Das Gemisch von nun sich gebildeten Gasblasen und Wasser wird in einen zweiten Behälter (2) geleitet, in welchem die Gasblasen nach oben aufsteigen und sich somit vom Wasser abtrennen.The mixture of gas bubbles and water now formed is passed into a second container ( 2 ), in which the gas bubbles rise upwards and thus separate from the water.
Der zweite Behälter ist notwendig, da sich die gebildeten Gasblasen un ter Ultraschalleinwirkung nur schlecht aus Flüssigkeiten entfernen.The second container is necessary because the gas bubbles formed un Remove ultrasound exposure from liquids poorly.
Im oberen Teil des Behälters befindet sich ein selbsttätiger Verschluß wie er aus der Heizungstechnik bekannt ist. Hier entweicht nun nahezu das gesamte, zuvor gasförmig gelöste Chlorgas über den wartungs freien selbsttätigen Entlüfter aus dem Trinkwasser. Das Chlorgas kann alkalisch absorbiert werden oder ins Freie geleitet werden.There is an automatic closure in the upper part of the container as it is known from heating technology. Here almost escapes all the chlorine gas previously dissolved in gaseous form above the maintenance free automatic deaerator from the drinking water. The chlorine gas can be absorbed alkaline or discharged outdoors.
Die Steuerung bzw. das Einschalten des Ultraschallgenerators wird durch die Wasserentnahme gesteuert. Die Anlage arbeitet kontinuierlich und kann in ihrer Leistung beliebig geregelt werden. Wenn das Wasser nach dieser Behandlung die Druckleitung verläßt, werden keine Gase mehr freigesetzt. The control or switching on of the ultrasonic generator is controlled by water withdrawal. The plant works continuously and can be regulated in their performance arbitrarily. If the water after this treatment leaves the pressure line, no gases released more.
Die beschriebene Anlage ist auch anwendbar bei industriellen Verbrau chern. Sie benötigt nur wenig Energie und arbeitet wartungsfrei.The system described can also be used for industrial consumption chern. It requires little energy and is maintenance-free.
Insbesondere Anlagen zum Erzeugen analytisch reinen Wassers wer den durch Vorschalten der Entgasungsanlage entscheidend wirkungs voller, da z. B. Chlorgas durch vorgeschaltete Aktivkohlefilter nicht zu rückgehalten wird. Auch nachfolgende Ionenaustauscher Harze sind wirkungslos und das Chlor verbleibt im angeblich reinen Endprodukt.In particular plants for the production of analytically pure water the decisive effect by connecting the degassing system upstream fuller because B. chlorine gas through upstream activated carbon filter is withheld. Subsequent ion exchangers are also resins ineffective and the chlorine remains in the supposedly pure end product.
Gerade in Entwicklungsländern mit üblicherweise starker Überchlorie rung stellt das Erstellen analytisch reinen Wassers bisher ein großes Problem dar.Especially in developing countries with usually high levels of overchlorine So far, the creation of analytically pure water has been a major task Problem.
Da die vorgestellte Anlage sehr preisgünstig zu erstellen ist, wäre sie gerade für solche Länder von hohem Nutzen. Since the system presented is very inexpensive to build, it would be of great benefit especially for such countries.
Nach Anlieferung des Trinkwassers beim Verbraucher wird die Anlage an den Hausanschluß (3) angeschlossen. Das Wasser durchläuft Behäl ter (1), an diesem befindet sich ein Ultraschallgenerator (4), welcher überschüssig gelöste Gase aus dem Wasser freisetzt.After delivery of the drinking water to the consumer, the system is connected to the house connection ( 3 ). The water passes through container ( 1 ), on which there is an ultrasonic generator ( 4 ), which releases excess dissolved gases from the water.
Das Wasser gelangt danach in Behälter (2), hier trennen sich die ent standenen Gasblasen vom Wasser ab und entweichen am Entlüfter (5).The water then enters the tank ( 2 ), where the gas bubbles are separated from the water and escape at the breather ( 5 ).
Das gasfreie Wasser durchläuft einen Sensor (6), der die Leistung des Ultraschallgenerators in Abhängigkeit zum Wasserdurchsatz steuert. Die Entnahme des gasfreien Wassers erfolgt nun über die im Haus be findlichen Wasserhähne (7).The gas-free water passes through a sensor ( 6 ) which controls the output of the ultrasound generator as a function of the water throughput. The gas-free water is now removed using the taps ( 7 ) in the house.
