Patent attributes
A static mixing device for use within an open channel includes a mixing section with at least one set of stationary mixing vane members and at least one conical section. In one example, the at least one conical section is an inlet section positioned upstream of the mixing section, while in another embodiment the at least one conical section includes both an inlet section positioned upstream and an outlet section positioned downstream of the mixing section. A plurality of vane members are also supported within the mixing section to promote fluid mixing. When used in an open channel, the static mixer having at least one conical section has a lower head loss in a shorter distance downstream from the mixing device than other conventional static mixers. In addition, the mixer is self-contained and is easy to mount, lightweight, and less expensive to manufacture and maintain than conventional open channel mixers.
