Förfarande och anordning för reglering av gränsytan mellan två kontrollerat strömmande och från varandra separerbara lösningar samt av ledning av båda lösningarna ut separeringsutrymmet |
摘要 |
<p>The invention relates to a method for adjusting the boundary surface between the two mutually separable solutions in liquid-liquid extraction at the discharge end of the separation part and for preventing the aeration of the solutions when discharging them from the separation part, so that the overflow height of the settled, lighter organic solution is maintained constant. In order to adjust the boundary surface in between the mutually separable solutions, the overflow height of the heavier aqueous solution is adjusted by conducting the settled aqueous solution from down upwards through tubular elements, in which case the height of these overflow pipes can be adjusted. The aeration of the solutions when discharging them from the separation part is prevented by conducting the solutions into transfer pipes through covered, shaft-like weir boxes that are deeper than the discharge end. The invention also relates to an apparatus whereby the boundary surface between the solutions is adjusted and the aeration prevented.</p> |
