Description

Verfahren zur Enthärtung von Kesselspeisewasser. Die Erfindung betrifft ein Verfahren zur Enthärtung von Kesselspeisewasser und besteht an erster Stelle darin, daß der in einer Kesselanlage entwickelte Dampf in hochüberhitztem Zustande zur Mischung des Dampfes mit dem für den Kesselbetrieb erforderlichen Zusatzspeisewassers einer Einrichtung zugeführt wird, in welcher die Verdampfung des Zusatzwassers zu Hochdrucktrockendampf unter gleichzeitiger Ausfällung der Härtebildner erfolgt.Process for softening boiler feed water. The invention relates to a process for softening boiler feed water and consists in the first place in the fact that the steam developed in a boiler system is in a highly superheated state for mixing the steam with the additional feed water required for boiler operation is fed to a device in which the evaporation of the make-up water High-pressure dry steam takes place with simultaneous precipitation of the hardness components.

Daß Enthärten von Wasser durch Einleiten von überhitztem Wasserdampf in das Wasser ist bekannt. Von diesem bekannten Verfahren unterscheidet sich das angemeldete dadurch, daß das Zusatzwasser in den überhitzten Betriebsdampf eingeführt und dabei verdampft wird.That softening of water by introducing superheated steam in the water is known. This differs from this known method registered by the fact that the make-up water is introduced into the superheated operating steam and is vaporized in the process.

Der ganze hier entwickelte, mit dem Kesseldampf gemischte ' Hochdrucktrockendampf geringerer Spannung als die des Kesseldampfes wird dann zu den Maschinen abgeführt, nachdem er noch einer Reinigung vor den mitgeführten Staubteilchen unterzogen ist.All of the high-pressure dry steam developed here, mixed with the boiler steam lower voltage than that of the boiler steam is then discharged to the machines, after it has been subjected to a cleaning before the dust particles carried along.

Abb. i und z zeigen eine zur Ausführung des neuen Verfahrens geeignete Vorrichtung im Höhenschnitt und in einem Querschnitt nach A-B der Abb. i.Figs. I and z show one suitable for carrying out the new method Device in vertical section and in a cross section according to A-B of Fig. I.

Der in einem Behälter a angeordneten Mischeinrichtung i, z, 3 wird durch den Stutzen 6 hocherhitzter Kesseldampf zugeführt, um mit durch den Stutzen 7 hinzutretenden Zusatzspeisewasser gemischt zu werden. Der hierbei entwickelte, mit dem Kesseldampf gemischte Hochdrucktrockendampf, durchströmt. ein über der Mischeinrichtung angeordnetes Siebblech q., welches eine nochmalige Durcheinandermischung des gesamten neuerzeugten Dampfes bewirken soll. Die Dampfgeschwindigkeit ist vor und hinter dem Siebblech eine geringe und soll o,i m nicht überschreiten. In den Bohrungen des Bleches ist aber die Geschwindigkeit eine bedeutend höhere, und es tritt daher beim Austreten aus ihnen eine Wirbelung des Dampfes ein, die bezweckt, eine etwa ungleichmäßige vorherige Mischung des Wassers mit dem im Kessel erzeugten Dampf auszugleichen.The mixing device i, z, 3 arranged in a container a is through the nozzle 6 highly heated boiler steam supplied to with through the nozzle 7 to be mixed with the additional feed water. The developed here, high-pressure dry steam mixed with the boiler steam, flows through it. one above the mixer arranged sieve plate q., which a repeated mixing of the entire to cause newly generated steam. The steam speed is in front and behind the sieve plate a small and should not exceed o, i m. In the holes of the sheet, however, the speed is significantly higher, and therefore it occurs when emerging from them a whirling of the steam, which is intended, for example uneven previous mixing of the water with the steam generated in the boiler balance.

Die hierauf folgende Reinigung des Dampfes von noch mitgeführten Staubteilchen geschieht dadurch, daß der Dampf weiter in dünnen Schichten über die Dampfkämme 5 geleitet wird, wobei die Gesch-,vindigkeit des Dampfes 0,05 m nicht überschreiten soll. Da auch die feinsten Staubteilchen schwerer als Dampf sind, so fallen sie aus der Dampfschicht heraus und legen sich hinter den in kurzen Abständen aufrecht hintereinander angeordneten kammartig wirkenden Stegen 5 nieder, indem dem Dampf zugleich die Möglichkeit genommen ist, den einmal niedergelegten Staub wieder aufzunehmen. Der gereinigte Hochdrucktrockendampf verläßt den Behälter a bei B.The subsequent cleaning of the steam from dust particles that are still carried along takes place in that the steam is passed on in thin layers over the steam combs 5, the speed of the steam not exceeding 0.05 m. Since even the finest dust particles are heavier than steam, they fall out of the steam layer and lie down behind the comb-like-looking webs 5, which are arranged upright one behind the other at short intervals, while at the same time the steam is deprived of the possibility of absorbing the dust once it has been deposited. The cleaned high-pressure dry steam leaves container a at B.
