Abstract
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.

A gas dispersion system, comprising:
- 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, comprising:
- a hub;
- and
- a plurality of blade pairs, each blade pair including an upper blade and a lower blade secured to the hub and extending generally radially away from the hub, the upper blade and the lower blade each being tapered so as to have a first width at an outer edge and a second narrower width at an inner edge,
- wherein the upper blade and the lower blade each have a trailing edge and the trailing edges of respective upper and lower blades are separated by a gap configured to allow fluid to flow therethrough.
A mixing element for gas dispersion operations, the mixing element comprising:
- a hub;
- and
- a plurality of blade pairs, each blade pair including an upper blade and a lower blade secured to the hub and extending generally radially away from the hub, the upper blade and the lower blade each being tapered so as to have a first width at an outer edge and a second narrower width at an inner edge,
- wherein the upper blade and the lower blade each have a trailing edge and the trailing edges of respective upper and lower blades are separated by a gap configured to allow fluid to flow therethrough.
