Description

Die Erfindung betrifft eine Vorrichtung zur Behandlung von karbonathaltigem Wasser mit Säure. Bei der Aufbereitung von Wasser ist es je nach der Höhe der Karbonathärte und nach dem dadurch bedingten Verfahren der chemischen Aufbereitung oft notwendig, durch Zusatz von Säure die Alkalitätszahl zu regeln. Durch die Säureeinwirkung entsteht freie Kohlensäure, welche aus dem Wasser möglichst schnell wieder ausgeschieden werden muß, weil sie alle Eisenteile angreift. Gemäß der Erfindung wird deshalb in die Rohrleitung, welche das mit Säure versetzte Wasser führt, ein Gasabscheider eingebaut, aus welchem das C02 abgeleitet wird. Erst nachdem das CO2 entfernt ist, wird das Wasser zu dem Wasserbehälter oder dem thermischen Entgaser weitergeleitet.The invention relates to a device for the treatment of carbonate Water with acid. When treating water, it depends on the level of carbonate hardness and often necessary according to the chemical processing process that this entails, to regulate the alkalinity number by adding acid. The effect of the acid arises free carbon dioxide, which is excreted from the water as quickly as possible must be because it attacks all iron parts. According to the invention, therefore A gas separator is placed in the pipeline that carries the acid-mixed water built in, from which the C02 is derived. Only after the CO2 has been removed the water is passed on to the water tank or the thermal degasser.

Der Gasabscheider wird vorteilhaft als Prallflächenabscheider ausgebildet, wenn die Mischrohrstrecke kurz ist, damit in dem Abscheider noch die Reaktion beendet und das CO, vollständig ausgeschieden wird. Ist eine Mischung nicht mehr notwendig, dagegen eine wirkungsvolle und raumsparende Abscheidung erwünscht, so wird ein Fliehkraftabscheider vorzuziehen sein. Der Abscheider wird zweckmäßig mit einem säurefesten inneren Belag versehen, damit er durch die Säure nicht angegriffen wird. Das gleiche gilt für die Mischrohrleitung.The gas separator is advantageously designed as a baffle separator if the length of the mixing tube is short so that the reaction in the separator is still terminated and the CO 2 is completely eliminated. If a mixture is no longer necessary, but an effective and space-saving separation is desired, a centrifugal separator is preferable. The separator is expediently provided with an acid-proof inner coating so that it is not attacked by the acid. The same applies to the mixing pipeline.

In der Zeichnung ist die Anordnung schematisch dargestellt. Das aus einer chemischen Wasserreinigungsanlage kommende Wasser, das reichlich Na H C 03 mit sich führt, fließt durch das Rohr i in der Pfeilrichtung. Ihm wird durch das Rohr 2 in vorher bestimmter Menge eine Säure, etwa H2 S 04, zugesetzt. Beim weiteren Durchströmen des hinter dem Impfpunkt liegenden Rohrteiles 3 tritt die Mischung und die chemische Umsetzung ein nach der Formel 2NaHC03 + H2S04= Na2S04 + H20 + C02. Das Gemisch gelangt in den Gasabscheider 4 und trifft.auf die Prallwand 5. Daher scheidet sich das CO, ab und strömt durch das Rohr 6 ab, während das Wasser durch das Rohr 7 in den thermischen Entgaser 8 fließt, in welchem es mittels Wasserdampf in bekannter Weise auf etwa 1o3° C erhitzt und dadurch auch von dem Restgehalt an Gasen praktisch befreit wird.The arrangement is shown schematically in the drawing. The water coming from a chemical water purification plant, which carries plenty of Na HC 03 with it, flows through the pipe i in the direction of the arrow. An acid, such as H2 S 04, is added to it through the pipe 2 in a predetermined amount. As the flow continues through the pipe part 3 located behind the inoculation point, the mixture and the chemical conversion occur according to the formula 2NaHC03 + H2S04 = Na2S04 + H20 + C02. The mixture enters the gas separator 4 and hits the baffle 5. Therefore, the C O separates and flows out through the pipe 6, while the water flows through the pipe 7 into the thermal degasser 8, in which it is vaporized Heated in a known manner to about 1o3 ° C and thereby also practically freed from the residual gas content.
