US 2020/0368701 A1 · STATIC MIXER WITH CURVED FINS

Abstract

A static mixer includes a tubular body having a sidewall with an upstream end, a downstream end opposite the upstream end, and an inner surface. The upstream end has a surface defining an upstream opening into the body. The downstream end has a surface defining a downstream opening exiting the body. The upstream opening, the downstream opening, and inner surface define a passageway through the body for transport of a first fluid therethrough. A primary fin may depend from the inner surface of the body and into the passageway. The primary fin may have a curved fin with a flow surface. A secondary fin may extend into the passageway adjacent to the primary fin, the secondary fin may have a curved flow surface that curves opposite to the flow surface of the primary fin. The secondary fin may be offset upstream or downstream from the primary fin.

Dependent claims

A static mixer, comprising:

a tubular body having a sidewall with an upstream end, a downstream end opposite the upstream end, and an inner surface;
a passageway extending between the upstream end and downstream end constructed and arranged to transport a first fluid therethrough and including a central axis;
a primary fin comprising:
a spine supported on the inner surface of the sidewall and extending into the passageway towards the central axis;
a first fin and a second fin each comprising:
a support edge disposed on opposite sides of the spine;
a tip;
a leading edge;
a trailing edge;
and
a curved flow surface that curves away from the sidewall;
wherein the first fin and second fin are positioned on the spine so that the leading edge is positioned upstream from the trailing edge.
