A gas dispersion system may include a drive mechanism, a drive shaft having a proximal end operably coupled to the drive mechanism, extending to a distal end, and configured to transfer rotational motion and torque, a mixing element arranged at or near the distal end of the drive shaft including a hub and multiple blade pairs, each blade pair including an upper blade and a lower blade secured to the hub and cantilevering freely and generally radially away from the hub.

Gas dispersion system

A mixer impeller having high efficiency blades. The impeller may include a central hub and a plurality of blades attached to and extending radially outwardly from the hub such that leading edges thereof are inclined upwardly from trailing edges thereof. Each of the blades may include a root attached to the hub, a tip, a first crease extending along substantially an entire length of the blade dividing the blade into a leading portion and a trailing portion, the leading and trailing portions meeting at the first crease such that the leading portion is angled downwardly from the trailing portion, and a second crease extending from a portion of the leading edge of the leading portion between the root and the tip diagonally along the leading portion to the tip, the second crease intersecting the tip at a point spaced from a point where the first crease intersects the tip, the second crease forming a tip portion of the leading portion that needs a remainder of the leading portion such that the tip portion is angled downwardly from the leading portion.

High efficiency mixer-impeller

A static mixer element and a method for mixing first and second (or more) fluids using a static mixer element. The static mixer element includes a directional flow axis which points in an intended downstream direction opposite to an intended upstream direction. The static mixer element also includes interdigitated static mixer blades. The blades each have a concave side which faces generally in the intended upstream direction at an acute angle with respect to the intended upstream direction. The static mixer element is placed in a pipe with the directional flow axis of the static mixer element pointing downstream. The first and second fluids are introduced into the pipe upstream from the static mixer element. Optionally, other static mixer elements can be added downstream, wherein even-numbered elements are rotated ninety-degrees about the directional flow axis from odd-numbered static mixer elements.
