Description
Mehrstufige, mit einer Lauge- als Kältemittel betriebene Vakuum-Kältemaschine. In der chemischen Industrie sind häufig Kühlprozesse erforderlich, die bezwecken, durch Kühlung irgendeiner Lauge bestimmte Salze auszuscheiden.Multi-stage vacuum refrigeration machine operated with a lye as refrigerant. In the chemical industry, cooling processes are often required with the aim of to excrete certain salts by cooling some lye.
Für diesen Kühlprozeß kann man Wasserdampfkältemaschinen, und zwar am besten mehrstufige Anlagen, verwenden, d. h. also, man kühlt die Lauge erst bis zu einer- bestimmten Temperatur ab, die einem bestimmten Vakuum entspricht, läßt die Lauge sodann überfließen in einen zweiten Apparat und kühlt hier auf eine tiefere Temperatur, entsprechend einem höheren Vakuum wie im ersten Apparat usw.For this cooling process you can use steam chillers, namely it is best to use multi-stage systems, d. H. So, you first cool the lye until to a certain temperature, which corresponds to a certain vacuum, can the lye then overflows into a second apparatus and cools here to a lower one Temperature, corresponding to a higher vacuum than in the first apparatus, etc.
Bei allen diesen Prozessen ist das Produkt, das aus der Anlage abfließt, ein Gemisch von Salz und Lauge, die sogenannte Endlauge, die zwar eine tiefe Temperatur besitzt, aber für den weiteren chemischen Prozeß wertlos ist. Diese Endlauge soll nun für die Niederschlagung des Brüdens, der in einer Stufe höherer Temperatur erzeugt worden ist, dienen.In all of these processes, the product that flows out of the system is a mixture of salt and lye, the so-called final lye, which has a low temperature possesses, but is worthless for the further chemical process. This final liquor should now for the suppression of the vapors, which produce a higher temperature in a stage has been serving.
In der Zeichnung sind vier Verdampfer V, bis v4 angenommen.In the drawing, four evaporators V to v4 are assumed.
Die Lauge fließt. bei o in den ersten Ver-Flampfer v,, kühlt sich beim Eintreten in den Apparat ab, läuft durch das Verbindungsrohr r, in den zweiten Apparat v2, in welchem das Vakuum besser ist als in v1 und also entsprechend auch die Abkühlung eine noch weitergehende wird. Von v2 gelangt die Flüssigkeit weiter durch r2 in den nächsten Verdampfer vß. Hier wird die Kühlung noch weitergetrieben usf. Der Brüden aus dem letzten Verdampfer v4, also demjenigen Verdampfer, aus dem die Endlauge direkt durch das Rohr i in das Gefäß 92 läuft, wird durch den Dampfstrahlapparat s4 - verdichtet und durch das Rohr b4 in den Oberflächenkondensator k1 gedrückt. In k1 wird der Wasserdampf durch Oberflächenkondensation niedergeschlagen und die Luft auf irgendeine Weise abgesaugt.The lye flows. at o in the first evaporator v ,, cools on entering the apparatus, runs through the connecting pipe r, into the second Apparatus v2, in which the vacuum is better than in v1 and therefore also accordingly the cooling becomes even more extensive. The liquid continues from v2 through r2 into the next evaporator vb. Here the cooling is carried out even further etc. The vapors from the last evaporator v4, i.e. the evaporator from which the final liquor running directly through tube i into vessel 92 is through the steam jet apparatus s4 - compressed and pushed through the pipe b4 into the surface capacitor k1. In k1 the water vapor is deposited by surface condensation and the Air evacuated in some way.
Der Brüden aus dem Verdampfer vs gelangt durch das Rohr b3 in einen Gegenstrommischkondensator m3. Der größte Teil des Brüdens aus v3 wird nun durch die Endlauge, die von der Pumpe p abgesaugt und durch das Rohr c in den Mischkondensator in, gehoben wird, niedergeschlagen. Der Rest des Brüdens, zusammen mit der nichtkondensierbaren Luft, wird durch den Dampfstrahlapparat s3 in eine Sammelleitung gedrückt, die zu einem Oberflächenkondensator k2 führt. Hierin wird der Restbrüden, zusammen mit dem Betriebsdampf, kondensiert und die Luft auf irgendeine Weise abgesaugt.The vapor from the evaporator vs passes through the pipe b3 into a Countercurrent mixing condenser m3. Most of the brother from v3 is now through the final liquor that is sucked off by the pump p and through the pipe c into the mixing condenser in, is lifted, dejected. The rest of the brothers, along with the non-condensable Air is pressed through the steam jet device s3 into a collecting line that closes a surface capacitor k2 leads. The remaining vapors are here, together with the operating steam, condenses and the air is sucked off in some way.
Der Strahlapparat s3 braucht nur einen Bruchteil der Leistung des Strahlapparates s4 zu besitzen, da, wie schon ausgeführt, der größte Teil des Brüdens durch Mischkondensation bereits niedergeschlagen ist.The jet device s3 only needs a fraction of the power of the To own the jet apparatus s4, as already stated, is the largest part of the brother has already been precipitated by mixed condensation.
Die aus ins abfließende Lauge gelangt durch ein Rohr hl in den Mischkondensator in2, der den Brüden von v2 niederschlägt. Wegen des Vakuumunterschiedes zwischen in , und in, ist h.1 schwanenhalsartig ausgebildet.The liquor flowing out into the outflow reaches the mixing condenser in2 through a pipe hl, which precipitates the vapors from v2. Because of the vacuum difference between in , and in, h.1 is designed like a gooseneck.
Der Restbrüden von m2 wird wiederum durch den Strahlapparat s2 in die Sammelleitung s1 gedrückt und gelangt in den Oberflächenkondensator k2, wo die Kondensation stattfindet. Bezüglich der Größe von s2 gilt das über s$ Gesagte.The remaining vapors of m2 are again through the jet machine s2 pressed into the collecting line s1 and gets into the surface capacitor k2, where the condensation takes place. With regard to the size of s2, what has been said about s $ applies.
Aus in 2 gelangt schließlich die Endlauge in den Mischkondensator ml, der den Brüden aus v1 niederschlägt. Der Restbrüden wird wiederum zusammen mit der Luft in die Sammelleitung l durch einen Strahlapparat s, gedrückt, für den wiederum das gleiche wie für s2 und s3 gilt.From in 2 the final liquor finally reaches the mixing condenser ml, which precipitates the vapors from v1. The residual vapor is again pressed together with the air into the collecting line 1 by a jet device s, for which the same applies as for s2 and s3.
Aus ml läuft die Endlauge schließlich angewärmt durch das Fallrohr f in das Gefäß g'.From ml the final liquor finally runs warmed up through the downpipe f into the vessel g '.
Die Dampfstrahlapparate s. bis s" lassen sich natürlich genau so gut durch rotiernde Luftpumpen ersetzen. Es muß nur darauf geachtet werden, daß die Schleuderflüssigkeit nicht Wasser, sondern eine Flüsigkeit mit tiefliegendem Siedepunkt; ist.The steam jet devices s. To s "can of course be used just as well replace with rotating air pumps. You just have to make sure that the Centrifugal liquid not water, but a liquid with a low boiling point; is.
