摘要:
An apparatus and a method for dispersing particulate materials prone to agglomeration, in a liquid. Particulate materials are exposed to a liquid and put into that liquid to form a suspension or a dispersion in a controlled method thereby minimizing agglomerates. The method uses mechanical/hydro mixing that prevents the physical deterioration of the particulate material and inhibits agglomeration of the particles. In many cases, these materials may be nanomaterials. Almost all particulate materials can be handled in this manner. This method has been found to be especially useful for preparing solutions of exfoliated graphene and certain drugs.

An apparatus for manufacturing carbonated water according to the invention can quickly produce carbonated water with a high carbonic acid gas content which does not easily lose carbonic acid gas and hence satisfactorily stimulates the throat with agreeable pungency. Since it has a simple configuration and hence is economic and effective, it can suitably be used in an carbonated beverage supplying apparatus such as an automatic vending machine, an automatic dispenser or the like. With such an arrangement, the apparatus improves its safety and hence can constantly supply delicious carbonated water.

Apparatus and method of hydrating a particulated polymer and producing a well treatment gel includes a mixer for spraying the polymer with water at a substantially constant water velocity and at a substantially constant water spray pattern at all flow rates of the water. A centrifugal diffuser is connected to the mixer for receiving the mixture, centrifugally diffusing the motive energy of the mixture, and hydrating the mixture into a gel. A centrifugal separator and constant velocity jet pump may be connected between the mixer and the centrifugal diffuser. A dilution valve is connected to the discharge of the centrifugal diffuser for mixing water with the gel at a substantially constant mixing energy at all flow rates of the gel and producing a diluted gel. A viscometer may be connected to the discharge of the dilution valve for measuring the viscosity of the diluted gel and regulating the flow of gel from the centrifugal diffuser to the dilution valve in order to control the viscosity of the diluted gel.
