Pulsating column with packing in baskets.

摘要

The packing of the pulsed column permits an extended exchange of the solid phase with the liquid phase.
<??>This packing consists of a stack of baskets (20) and of crown rings (22) provided with a central hole (24).
<??>In addition to rapid low-energy pulsation, the interior of the column is subjected, at a very low frequency, to a high-energy pulsation to remove a proportion of the solid phase present in a basket and to make it descend towards a lower basket.
<??>Application to all pulsed columns operating with a divided solid phase and a liquid phase.
