Process for cleaning the openings in the form of charters of tube distribution and collection on an ion exchange column

摘要

A method of and device for cleaning the slot-like openings of distribution and collection pipes of a continuously operating ion exchanger column. During the treatment phase, the ion exchange particles within the ion exchanger bed do not exchange places, and the bed has an axial movement without temporal interruption. The medium stream which flows through the distribution and collection pipes undergoes a flow reversal for a limited time in periodic succession with initial reduction of the rate of flow.
