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.
Claims20
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 huh and cantilevering freely and 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.
The gas dispersion system of claim I, wherein the upper blade and the lower blade of the plurality of blade pairs extend along substantially parallel radial lines.
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 cantilevering freely and 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.
