Description

Verfahren und Einrichtung zur entfernung vori Stick@toff aus Wasser Grundwasser ist oft und Oberflächenwasser fnst in e @@it otickstoffgas gesättigt. Bei einer evtl. Aufbereitung das Wassers ist es nur. oftmals notwendi@, das Wasser nit Saners toff anzureloh£rn, was durch Zumischung von Luft geschieht. Tn offener Anlage macht dieL keine Schwierigkeiten. Anders ist dies aber bei Anlagen, die in geschlossener Form unter Druck ar@eitan, Wegen des hohen Stickstoffanteiles in der Luft treten bekanntlich nach der Luftbehandlung des Was@ers beim Entspannen des Wassers Gastrübungen auf, weil das zur Auf@ereitung gelangende Wasser mei@t schon vor der Luftzumischung stickstoffgesättigt was (bei Atmosphärendruck gerechnet) und bei der Luttschandlung weiterer Sticksoff aufgenommen wurde. Eine solche an ich und hygienisch unbedenkliche Stickstoffgastrübung beim Wasserzapfen macht beim Konsumenten einen optischen nachteili;;£n Eindruck und wird daher abgelehnt. Method and device for removing stick @ toff from water Groundwater and surface water are often saturated in nitrogen gas. If the water is possibly treated, it is only. often necessary, the water It is not possible to use sanitizers to teach what happens when air is mixed in. Tn more open The plant does not cause any problems. This is different, however, for systems that are in closed form under pressure ar @ eitan, because of the high nitrogen content in the It is well known that air occurs after the water has been treated with air when the Water gas cloudiness, because the water that is being treated is already nitrogen-saturated before the air is added (calculated at atmospheric pressure) and further nitrogen was absorbed during the Luttschlung. Such at I and hygienically harmless nitrogen gas opacity when tapping water makes when Consumers a disadvantageous visual impression and is therefore rejected.

L?.r diese Schwierigkeiten bei geschisssenen Anlagen und in anderen Fällen, wo dieo nachteilig sein könnte, abzustellen, @ieht die Erfindung vor, das Vakuum, welches beim Fördern von Was@er vor der Pumpe auftritt, für eine Entgasung auszunutzen, Zu diesem Zweck wird zwischen Brunnen und Förderpumpe ein Entgnssungskessel eingeschaltet, der 1.) eine zweckmässige Innenausstattung zur möglichst weitgehenden Entgasung erhält, 2.) eine zweckmässige Grösse erhilt, damit das zu entgasende Was@er cine genägende Zeit zur Entgasung besitzt, 3.) in seiner Ordinatenhöhe so zur Fumpe aufgestellt wird, dass er bei geringen baulichem Aufwand und bei den gegebenen örtlichen Verhiltnissen ein möglichst hohes Vakuum zeigt.L? .R these difficulties in closed systems and in others Cases where this could be disadvantageous, @ the invention provides that Vacuum that occurs when conveying Was @ er the pump occurs, to use for degassing, for this purpose between the well and the feed pump a degassing boiler switched on, the 1st) a functional interior for the greatest possible degassing, 2.) is given an appropriate size, so that the water to be degassed has sufficient time for degassing, 3.) in its ordinate height is set up in such a way to the pump that it is at low structural Effort and with the given local conditions a vacuum as high as possible shows.

Aus dem Entgasungsraum wird das ausgeschiedene Gas mittels einer geeigneten Vorrichtung, beispielsweise einer Vakuumpumpe entfernt.The separated gas is removed from the degassing chamber by means of a suitable one Device, such as a vacuum pump removed.

Die Innenausstattung des Entgasungebehälters kann in einer-Kaskadenanordnungoder einer Verdüsung bestehen; auch an@ere Möglichkeiten, wie z. B. Ausbreitung des Wassers in dänner Schicht, sind anwendbar.The interior of the degassing vessel may be in a cascade arrangement or consist of an atomization; also at @ ere possibilities, such as B. Propagation of water in a thin layer are applicable.

In der Zeichnung ist die Erfindung beispielsweise veranschaulicht, wobei in allen Fällen das Wasser aus dem Brunnen oder Senkbehälter 1 über die Förderleitung 2 in den Entgasungsbehälter 3 gelangt, aus dem eu über die Pumpeleitung 4 mittels der Waswerpumpe b abgesaugt wird, wä@rend die aubge3c'siedenen Gase am Kopf des Entgasungsbchälters 3 über die Gasleitu g 6 mittels des Gaspumpe 7 abgezogen werden. Unterschiedlich ist jeweile die Innenausstattung des Entgasungsbehilters 3. lieser Behilter enthält gemäss Fig. 1 kaskadenar@ig angeordtc Überlanfwehre 8 oder gemäss Fig. 2 über einander liegende Auffang- und Verrieselungstöpfe 9. In Fig. 3 ist eine Spräh-oder Verdisungsanordnung 13 und in Fig. 4 eine schrage Ablauffläche 11 zur Verteilung des Was cro in einer dünnen Schicht vorreschen. Druckverlust das Entgrsung bshälters, @sers, legel im Brunnen bzw. Ansaugebehälter, optigale Saughöhe der Förderpumpe, Wassertemperatur, usw. mässen @atürlich einander angepasst sein.In the drawing, the invention is illustrated, for example, in all cases, the water from the well or sump 1 via the delivery line 2 enters the degassing tank 3, from the eu via the pump line 4 by means of the water pump b is sucked off, while the boiling gases at the head of the Entgasungsbchälters 3 are withdrawn via the Gasleitu g 6 by means of the gas pump 7. Is different the interior of the degassing filter 3. According to FIG. 1, this container contains cascading weirs 8 or according to FIG. 2 overlying collecting and trickling pots 9. In FIG. 3 is a spraying or disintegration arrangement 13 and in FIG. 4 an inclined drainage surface 11 to distribute the Was cro in a thin layer. Pressure loss that Degassing bshalteers, @sers, legel in the well or suction container, optional suction height the feed pump, water temperature, etc. must of course be adapted to each other.
