METHOD AND APPARATUS FOR ADJUSTING THE CONCENTRATION OF ACIDS OR LYES

摘要

For adjusting the concentration of acids or lyes, in particular of sulfuric acid, the acid or lye is supplied through an inlet to a mixing chamber, is mixed therein with a medium for adjusting the concentration, and the concentration-adjusted acid or lye is discharged from the mixing chamber through an outlet. To achieve a uniform dilution of the acid or lye and small concentration deviations with low pressure loss, the medium for adjusting the concentration, in particular water, is charged to the acid or lye before the inlet to the mixing chamber and the acid stream or lye stream and the stream of the medium subsequently are deflected preferably by 90°.
