摘要
The cell includes an enclosure having, at the top, a main inlet for the pulp to be de-inked and, at the bottom, a main outlet for the de-inked pulp. The pulp from the top to the bottom, passes through successive stages provided with bubble passageways introduced into the lower portion of the enclosure, and the bubbles rise to the top, to form a foam. The cell includes pulp a guiding mechanism forming a guiding path and in which the bubble passageways are provided for. The guiding mechanisms are, on their lower face, inclined upwards in order to guide the bubbles towards the bubble passageways.
