摘要： Polymer activation apparatus for activating a liquid polymer emulsion in dilution water includes a first processing zone in which the polymer solution is subjected to a high mean shear rate for a predetermined period of time, and a second processing zone in which the polymer solution is subjected to a low mean shear rate for a longer period of time. The shear rates and residence times in the zones are selected to produce maximum activation in less total processing and aging time than that required in known apparatus.

摘要： The apparatus includes a frame in which a vessel is mounted. Water is delivered into the vessel through one inlet, polymer is delivered into the vessel through a second inlet, and a further liquid is delivered into the vessel through a further inlet. A pulsating pump delivers the polymer to the vessel and a continuously operated pump delivers the further liquid into the vessel. Either pump can be energized separately or both pumps can be energized depending upon the situation. For example, the polymer pump is energized when it is desired to deliver an emulsion polymer to the vessel and the other pump is energized when one wants to deliver a solution polymer.

摘要： Polymer activation apparatus includes an impeller in a mixing chamber having inlets for polymer and dilution water, and an outlet for removing the resulting solution. The impeller includes a circular disk having a plurality of internal channels which extend from an eye at the axis of the impeller to the impeller edge. The eye extends through the top surface of the impeller, and a shaft is secured to the bottom surface of the impeller to rotate it.A polymer inlet and a water inlet are provided within about 1 inch of the impeller eye, and are oriented so that the polymer and water are placed directly into the eye of the impeller, within about 11 milliseconds of the initial mixing of the polymer and water.

摘要： Dry polymer is fed from a hopper into the funnel-shaped path of a mixing structure which has upper and lower nozzle portions cooperating to define a frustoconical nozzle opening or eductor which provides communication between the path and a surrounding annular chamber. Water is delivered along the side of the chamber so that it swirls through the nozzle opening and is ejected into the funnel-shaped path in a conical swirling stream which mixes with dry powder falling along the path and forms a Venturi to draw the powder along the path. The swirling mixture is injected into the top of a vertical rotating tube which extends down into a container and carries an elongated hollow impeller at its lower end. The water polymer mixture is further mixed in the tube and sprayed through the impeller into an upper mixing compartment of the container. Liquid is drawn through openings in the bottom of the impeller to facilitate the mixing action. The mixture is then passed to a lower aging compartment, from which it is fed to auxiliary mixing and diluting means. Control means prevents feeding of the dry polymer in the absence of the conical water stream.
