ABSTRACT:
The invention provides a system for thoroughly wetting a dry polymer and mixing it with water, or another electrolyte, to make an electrolyte/polymer mixture. The system uses a funnel which has water introduced along a circumferential pattern therein to form a wall of swirling water over the inner wall of the funnel. The dry polymer is dropped into the eye of the impeller vortex. The spout of the funnel opens directly into the vortex or eye of an impeller of a pump which imparts substantial energy to the mixture. After the dry polymer is thoroughly wetted by the impeller action, the mixture is transferred to a mixing vessel where a large volume of air is blown through the mixture at a relatively low pressure while the mixture ages. The viscosity of the mixture is enhanced by the conformationally structuring of the polymer at the water/air interface of the blown air. After processing in the mixing vessel, the polymer is withdrawn and used for any suitable purpose. It may be sent into a liquid polymer processing system which activates the polymer. Or, it may be sent into a storage container for subsequent shipment to another location.
