Description
Verfahren zur Reinigung und Entgasung von Rohwasser unter Auskochung des Wassers. Es ist bekannt, Wasser zu reinigen, indem man es bei über 1400 C kocht. Es werden dadurch die gelösten Gase ausgetrieben. Durch das Entweichen der Kohlensäure fällt der wesentlichste Teil der vorübergehenden Härtebildner aus, während gleichzeitig der Gips in Anhydrid umgebildet und abgeschieden wird.Process for the purification and degassing of raw water with decoction of the water. It is known to purify water by boiling it above 1400 C. The dissolved gases are thereby expelled. By the escape of the carbonic acid the most essential part of the temporary hardeners precipitates while at the same time the gypsum is transformed into anhydride and deposited.
In den meisten Fällen ist man nicht in der Lage, das gereinigte Wasser mit etwa 15o1 C verwenden zu können. Es soll deshalb nach der Erfindung das Heißwasser stufenweise entspannt und der entstehende Brüden zur Vorwärmung des Rohwassers in mehreren hintereinander geschalteten Mischvorwärmern benutzt werden.In most cases one is unable to use the purified water to be able to use with about 15o1 C. It should therefore according to the invention the hot water gradually relaxed and the resulting vapor to preheat the raw water in several mixer preheaters connected in series can be used.
Die Vorteile der stufenweisen Entspannung gegenüber der Abkühlung, z. B-, im Gegenstrorn mit dem Rohwasser, liegen in der Vermeidung der großen, sonst nötig werdenden Austauschflächen, die zudem schnell verkrusten würden. Der Vorzug der stufenweisen Entspannung gegenüber der einmaligen geht aus Folgendem hervor: Wollte man z. B. das Heißwasser einstufig auf 5o1 C abkühlen, so könnte man das Rohwasser auch nur auf höchstens 5o1 C bringen. Bei stufenweiser Entspannung und Vorwärmung dagegen kann man die Vorwärmung beliebig nahe an die Heißwassertemperatur herantreiben.The advantages of gradual relaxation over cooling, z. B-, in countercurrent with the raw water, lie in avoiding the large, otherwise necessary exchange surfaces, which would also quickly become encrusted. The privilege the gradual relaxation compared to the one-off can be seen from the following: If you wanted to z. B. cool the hot water in one stage to 5o1 C, you could do that Bring raw water only to a maximum of 5o1 C. With gradual relaxation and Preheating, on the other hand, can be preheated as close as desired to the hot water temperature drive up.
Das Verfahren nach der Erfindung soll an Hand der schematischen Zeichnung näher erläutert «-erden.The method according to the invention should be based on the schematic drawing explained in more detail «-erden.
Das Rohwasser mit etwa 20' C Temperatur durchläuft zuerst die beiden Mischvorwärmer 1 und 2, in denen Luftleere herrscht, fließt dann der Pumpe 3 zu und wird von ihr in den Mischvorwärmer ,4 geschafft, der unter geringem Überdruck steht. Aus diesem strömt es vorgewärmt zur Pumpe 5, die es in den Reiniger 6 drückt, wo es auf 15o1 C erwärmt und bei dieser Temperatur gekocht wird.The raw water with a temperature of about 20 ° C first runs through the two Mixing preheaters 1 and 2, in which there is no air, then flows to pump 3 and is carried by it into the mixing preheater, 4, which is under slight overpressure stands. From this it flows preheated to the pump 5, which pushes it into the cleaner 6, where it is heated to 15o1 C and cooked at that temperature.
Das gereinigte Wasser steigt - wenn nötig durch einen Koksfilter - in den Entspannungsbehälter ;, «-o es im bezeichneten Falle in drei Stufen entspannt und dadurch abgekühlt wird. Der entstehende Dampf dient zur Beheizung der Mischvorwärmer. Das abgekühlte Reinwasser fließt zur Pumpe 8, die es in die. Kessel bzw. in gasgeschützte Behälter schafft.The purified water rises - if necessary through a coke filter - into the expansion tank; "-o it relaxes in three stages in the case described and thereby cooled down will. The resulting steam is used for heating the mixer preheater. The cooled pure water flows to the pump 8, which it in the. Creates boiler or in gas-protected container.
Die Luftleere erzeugt die Wasserstrahlpumpe 9, die von der Strahlwasserpumpe io mit Aufschlagwasser versorgt wird. Die Entlüftung des Rohwassers geht in den Vorwärmern i und a vor sich. Die Pumpen 3 und 5 werden von dem gleichen Motor angetrieben.The air void is generated by the water jet pump 9, which is operated by the jet water pump io is supplied with whipping water. The deaeration of the raw water goes into the Preheating i and a in front of you. The pumps 3 and 5 are driven by the same motor.
Ein nicht gezeichneter Schwimmer im Reiniger 6 regelt durch ein Ventil den Rohwasserzulauf nach dem Mischvorwärmer i. Das Schwimmerventil 1z steuert die dem Entspannungsbehälter 7 zufließende Reinwassermenge nach Maßgabe der Förderleistung der Pumpe B.A float, not shown, in the cleaner 6 controls through a valve the raw water inlet after the mixer preheater i. The float valve 1z controls the the expansion tank 7 flowing amount of pure water according to the delivery rate the pump B.
Die in die Zeichnung eingetragenen Temperaturen und Drücke sind nur beispielsweise zu verstehen. Die Druck- und Temperaturunterteilung kann natürlich auch anders erfolgen. Das gereinigte Wasser kann selbstredend nur mit chemisch gereinigtem, nicht aber mit destilliertem Wasser in Wettbewerb treten.The temperatures and pressures entered in the drawing are only for example to understand. The pressure and temperature subdivision can of course can also be done differently. The purified water can of course only be mixed with chemically purified, but do not compete with distilled water.
