ABSTRACT:
The method of circulation according to the invention consists in causing a part of the liquid part to rotate whereby centrifugal forces causes the rotating part of the liquid phase to form a rotating vortical liquid spindle that exerts a suction effect. The liquid to be circulated is then pumped into the spindle by suction, passes through a cavity destined for deposition of solid phase, said cavity being positioned in the space of the spindle, whereafter the liquid passes to the upper part of the spindle and is drawn back into a liquid phase container. The device for effecting this method of circulation consists of a vessel for liquid phase wherefrom the liquid phase is brought to a rotatable hollow body which incorporates a mantle, conveniently cylindrical, and a bottom which houses at least one opening for inlet of the liquid phase to the bottom of the body, or in some configurations a cover, said body being equipped by outlet openings for the exit of the liquid phase and having at least in its part at least one cavity for deposition and anchoring of solid phase, said cavity being provided in its part adjacent the axis of rotation or in its lower part with inlet openings for the liquid phase entering the cavity an incorporating in its part more distant from the axis of rotation or in its upper part outlet openings for the liquid phase leaving the cavity.
