Abstract
The cell 1 includes an upper cylindrical chamber 2 comprising at its center over its entire height a vertical ink removal pipe 4. A lower lateral pipe 9 receives via an opening 10 a paper pulp feed diluted in water and is fed with air from an upper pipe 12. Injectors placed on the pipe 9 inject the paper pulp and air into the chamber 2. Each injector has the shape of a tube with a constant diameter and opens at its outlet extremity through about twelve honeycomb-shaped orifices, thus ensuring a satisfactory dispersion of the air. The air bubbles lift up the ink particles so as to form a foam evacuated by the pipe 4.
