Static mixer assembly with deflection elements

A static mixer assembly, comprising:

• a flow duct having a given transverse extent and an axis of symmetry;
• and
• a static mixer being disposed in said flow duct and defining a free piece of said flow duct disposed downstream of said static mixer as seen in flow direction through said static mixer;
• said static mixer including:
• a) a multiplicity of deflection elements;
• b) said deflection elements being disposed in a plane being aligned at an angle relative to said axis of symmetry and in mutually parallel rows being aligned transversely to said axis of symmetry;
• c) said rows of said deflection elements are two directly adjacent pairs of rows disposed tightly next to each other;
• d) said deflection elements of each of said pairs of rows being inclined in the same direction along one side of said pair of rows and being inclined in a direction opposite to said deflection elements of a respective other side of said pair of rows;
• e) two adjacent pairs of rows being spaced apart by a given distance;
• f) said deflection elements being small in relation to the given distance between adjacent ones of said mutually parallel pairs of rows;
• and
• g) said given distance being small in relation to said given transverse extent.
