Mixing apparatus and method

摘要

A mixing apparatus includes a housing having an inner chamber, an inlet, and an outlet; an outlet conduit having a first and second end, the second end providing communication between the inner chamber and the outlet; and one or more dispersion members configured to mix one or more fluids, the one or more dispersion members extending between the outlet conduit and the housing. The dispersion members include a plate having a first and second side, a first opening in the plate for receiving an outlet conduit of the mixing device, and a plurality of second openings in the plate. The plurality of second openings has a first and second side. The first and second sides of the plurality of second openings have chamfered edges.

1. A method of mixing and diluting a concentrated fluid in a mixing device, the method comprising:
delivering the concentrated fluid into a stream of dilution fluid outside a housing of the mixing device, wherein the concentrated fluid comprises a plurality of polymers; supplying the concentrated fluid and the dilution fluid into the housing through an inlet; mixing the concentrated fluid and the dilution fluid in an inner chamber of the housing, wherein the mixing comprises:
passing the concentrated fluid and the dilution fluid through a plurality of openings in one or more dispersion members in the inner chamber of the housing to blend the concentrated fluid and the dilution fluid to form a mixed fluid; andpassing the concentrated fluid and the dilution fluid over a chamfered surface bounding a first opening to the plurality of openings to inhibit shearing of the plurality of polymers in the mixed fluid; discharging the mixed fluid through an outlet conduit from the inner chamber of the housing to an outlet of the housing, wherein a pressure of the concentrated fluid and the dilution fluid at the inlet forces the mixed fluid out of the housing through the outlet conduit and the outlet; and flowing the mixed fluid through a plurality of openings in a cap on an end of the outlet conduit in the inner chamber.
