VERFAHREN ZUR WEISSEREGELUNG FÜR DIE DRUCKFARBENENTFERNUNG IN DEINKING-ANLAGEN UND EINE DEINKING-ANLAGE MIT EINER FLOTATIONSZELLE ZUR DRUCKFARBENENTFERNUNG |
摘要 |
<p>The invention relates to a method for regulating whiteness for removal of printing ink in deinking installations, whereby printing ink particles in a fiber suspension are removed in a flotation cell (20) by means of gas bubbles. Said removal is carried out by removing the foam produced in a foam gutter (11), the amount of foam removed being adjusted. The method comprises the steps of measuring (24) a feed whiteness (ZW) of the fiber suspension added; determining an adjustable variable (SRN) as a function of the feed whiteness (ZW) and a predetermined desired value (SW) for an acceptor whiteness of the removed fiber suspension (26); adjusting the quantity of the removed foam subject to the adjustable variable (SRN).</p> |
