Static mixer

A mixing element for a static mixer configured to be installed into a tubular mixer housing, comprising:

• a plurality of installation bodies arranged in series along a longitudinal axis of the mixing element including
• a first installation body having a first wall element extending in a direction of the longitudinal axis, a first side wall and a second side wall arranged opposite the first side wall, a deflection element arranged adjacent to the first wall element,
• the deflection element having a deflection surface extending in a transverse direction to the first wall element at both sides of the wall element,
• the deflection surface having a first opening at a side facing the first side wall of the first wall element, a second wall element and a third wall element arranged adjacent to the first opening,
• the second and third wall elements extending in the direction of the longitudinal axis, each of the second and third wall elements having an inner wall and an outer wall extending substantially in the direction of the longitudinal axis,
• each of the inner walls and outer walls including an angle between 20° and 160° with one of the first and second side walls of the first wall element,
• the first opening of the deflection surface being arranged between the inner walls of the second and third wall elements, a second opening arranged outside one of the outer walls of one of the second and third wall elements,
• the second opening being disposed on the deflection surface at a side facing the second side wall of the first wall element,
• a first wall element of a second installation body adjoining the second and third wall elements,
• the first installation body being connected to the second installation body via a common bar element;
• and
• at least two separation elements connected to the bar element, the separation elements being located next to one another with respect to the longitudinal axis of the mixing element, and being formed as a projection extending only partially circumferentially around an inner wall of the mixer housing, each separation element of the separation elements defining a plane that is substantially perpendicular to the bar element.
