Description
Verfahren zur Aufbereitung für die Warmwasserbereitung bestimmten Wassers Das zur Speisung von Warmwasserbereitungsanlagen zur Verfügung stehende Wasser enthält in der Regel Sauerstoff und aggressive Kohlensäure, die auf Behälter und Zeitungen, welche aus unedlen Metallen, z. x3. Stahl, bestehen, korrodierend wirken. Die Korrosionswirkung ist umso stärker, je höher das Wasser erhitzt wird.Process for preparation for hot water production Water That which is available to feed water heating systems Water usually contains oxygen and aggressive carbonic acid, which on containers and newspapers made of base metals, e.g. x3. Steel, made of, corrosive works. The higher the temperature of the water, the stronger the corrosion effect.
Es sind eine ganze Reihe brauchbarer Verfahren bekannt, um Kesselspeisewasser derart aufzubereiten, daß es keine korrodierende Wirkung mehr hat. Diese Verfahlen sind aber für die Aufbereitung von Wasser, das nur mäßig, jedenfalls unter 100 00 zu erwärmen ist, zu aufwendig.A number of useful methods are known to provide boiler feed water to prepare in such a way that it no longer has any corrosive effect. These miscarriages but are for the treatment of water that only moderately, at least below 100 00 heating is too expensive.
Auch solche Verfahren, bei denen zwar die freie Kohlensäure beseitigt wird, jedoch nicht der Sauerstoff, oder mit denen eine Aufhärtung des Wassers verbunden ist, kommen in vielen Fällen nicht infrage. Auch solche Verfahren müssen ausscheiden, die den Salzgehalt des* Wassers erhöhen, oder bei denen Verbindungen zugegeben werden, die wegen ihrer Giftigkeit, z. B. bei Badewässern, nichtzulässig sind. Es ist das Ziel der Lrfindung, ein für die Warmwasserbereitung bestimmtes Wasser mittels eines Verfahrens aufzubereiten, das in verhältnismäßig einfachen Apparaten mit billigen Mitteln durchzuführen ist.Also, such processes in which although the excess carbon dioxide is eliminated, but not the oxygen, or with which a hardening of the water is connected, do not come into question in many cases. Processes must also be eliminated that increase the salt content of the water, or where compounds are added that, because of their toxicity, e.g. B. in bathing waters, are not permitted. It is the aim of the invention to prepare water intended for hot water preparation by means of a process that can be carried out in relatively simple apparatus with inexpensive means.
Gemäß der Erfindung begast man das für die Warmwasserbereitung bestimmte Wasser mit einem Inertgas, dab selbst auf das Zeitungssystem nicht korrodierend wirkt, und zwar in solchem Maße, dab der im Wasser enthaltene Sauerstoff und die freie Kohlensäure dabei praktisch entfernt werden. Als geeignetes Inertgas hat sich Stickstoff erwiesen. Die Verwendung von Stickstoff bietet sich besonders in Betrieben an, die einen höheren Bedarf an mehr oder weniger reinem Sauerstoff haben und infolgedessen über eine Luftzerlegungsanlage verfügen, besonders dann, wenn der sonstige Stickstoffverbrauch des Betriebes geringer ist als der entsprechende Verbrauch an Sauerstoff.According to the invention, the water intended for hot water preparation is fumigated with an inert gas that does not even have a corrosive effect on the newspaper system, to such an extent that the oxygen contained in the water and the free carbonic acid are practically removed. Nitrogen has proven to be a suitable inert gas. The use of nitrogen is particularly useful in companies that have a higher demand for more or less pure oxygen and consequently have an air separation plant, especially when the other nitrogen consumption of the company is less than the corresponding consumption of oxygen.
Für die Begasung mit dem Inertgas stehen die Apparaturen zur Verfügung, die für das Auswaschen von Bestandteilen aus Gasen mittels Flüssigkeiten durch chemische Bindung oder physikalische Lösung in Gebrauch sind. Die Apparatur kann besonders einfach gewählt werden, wenn Stickstoff in beliebigen Mengen zur Verfügung steht und es auf die Wirksamkeit des huswaschens weniger ankommt. Vorzugsweise erfolgt die Begasung mit dem Inertgas in der Weise, daß am Boden einer langsam absinkenden Wassersäule das Inertgas in Form möglichst feiner Blasen über den ganzen Querschnitt verteilt eingeführt wird. For gassing with the inert gas, the equipment is available that is used for washing out components from gases by means of liquids through chemical bonding or physical dissolution. The apparatus can be chosen particularly easily if nitrogen is available in any quantity and the effectiveness of the washing machine is less important. The inert gas is preferably gassed in such a way that the inert gas is introduced in the form of the finest possible bubbles over the entire cross section at the bottom of a slowly sinking column of water .
Eine Anlage zur Durchführung des neuen Verfahrens ist auf der anliegenden Zeichnung dargestellt; Hier bedeutet A den Vergasungsturm. Demselben wird über die Leitung 1 das aufzubereitende Wasser zugeführt und mittels der Beregnungsdüsen 2 verteilt. Dicht unterhalb derselben liegt der Flüssigkeitsspiegel. Durch die Leitung 3 wird Stickstoff dem als Brausensystem ausgebildeten Gasverteiler 4 zugeführt. Je feiner die Verteilung des Stickstoffs ist, umso größer ist seine Wirksamkeit. Die Größe@des BegaBungsturms A wird im Verhältnis zur aufzubereitenden Wassermenge beispielsweise so bemessen, daß das Wasser in dem Turm langsam absinkt. Der überschüssige Stickstoff zusammen mit dem bei der Entgasung frei werdenden Sauerstoff und dem Kohlendioxyd ziehen durch die Zeitung 5 ab.A system for implementing the new method is shown in the attached drawing; Here A means the gassing tower. The water to be treated is fed to the same via line 1 and distributed by means of sprinkling nozzles 2. The liquid level is just below it. Nitrogen is fed through line 3 to gas distributor 4, which is designed as a shower system. The finer the distribution of nitrogen, the greater its effectiveness. The size of the talent storm @ A is, for example, dimensioned in proportion to the amount of water to be treated, that the water drops slowly in the tower. The excess nitrogen together with the oxygen released during the degassing and the carbon dioxide are withdrawn through the newspaper 5.
Das aufbereitete Wasser verläßt den Begasungsturm A durch die Leitung 6 und wird der in beliebiger Weise ausgebildeten Heizvorrichtung B zugeführt. Der Was- serspeicher C, in den das erwärmte Wasser durch die Zeitung 7 gelangt, ist als Gasabscheider ausgebildet. Durch die Anwärmung des Wassers wird das Lösevermö- gen für Gase herabgesetzt; von dem aufgenommenen Stickstoff zieht also ein Teil durch die Leitung 8 ab. Durch die Zeitung 9 wird das von Sauerstoff und freier Kohlensäure befreite Wasser den Verbrauchern zugeführt.The treated water leaves the gassing tower A through the line 6 and is fed to the heater B, which can be designed in any way. The water reservoir C, into which the heated water passes through the newspaper 7, is designed as a gas separator. By heating the water, the dissolving power for gases is reduced; a part of the nitrogen absorbed is thus withdrawn through line 8. Through the newspaper 9, the water freed from oxygen and free carbonic acid is supplied to the consumers.
Das Verfahren ist für betriebe verschiedenster Art geeignet, insbesondere für die vielen Arten von Naschprozessen, bei denen der Gehalt an dem aufgenommenen Inertgas nicht stört. Das Verfahren hat sich besonders bewährt bei der Irrzeugung von Waru,-wasser für Badezwecke in Fabrikbetrieben und Siedlungen.The process is suitable for a wide variety of companies, in particular for the many types of snacking processes in which the content of the ingested Inert gas does not interfere. The procedure has proven itself particularly well in the case of false generation of waru water for bathing purposes in factories and settlements.
