Abstract
The static mixing element in a flow channel (7) has at least two deflectors (30) disposed on mountings (20) at a distance from the channel wall. The deflectors form an angle W of from 10.degree. to 45.degree. to the main flow direction Z. They have different orientations and the projection FZ of the deflectors in the main flow direction amounts to from 5% to 50% of the channel cross-section F. Cross-flows providing very efficient transverse mixing are therefore produced in a simple manner. When dispensing tubes (20, 21) are used as mountings a very effective mixing device is provided.
Claims13
A static mixing element in a flow channel, comprising:
- a flow channel having a channel cross-sectional area and a channel wall defining a main flow direction;
- an injection system including at least one directed dispensing tube for injecting another [liquid] fluid into the flow channel, the at least one directed dispensing tube including an outlet orifice having a tube axis;
- and
- at least two deflectors each being attached to a mounting at a distance from the channel wall, the at least two deflectors forming an angle of between 10.degree. to 45.degree. relative to the main flow direction, a projection of the at least two deflectors in the main flow direction being 5% to 50% of the channel cross-sectional area;
- the at least one dispensing tube being said mounting for at least one of the at least two deflections, the at least one of the at least two deflectors being disposed at the outlet orifice of the dispensing tube.
A static mixing arrangement, comprising:
- a flow channel having a channel cross-sectional area and a channel wall defining a main flow direction;
- a plurality of mountings positioned in the flow channel and extending in the main flow direction;
- a plurality of cylindrical deflectors mounted to the plurality of mountings, the plurality of deflectors having an axis forming an angle of between 10.degree. to 45.degree. to the main flow direction, wherein each of the plurality of mountings have a group of the plurality of deflectors mounted thereon the deflectors on each mounting being staggered so that adjacent deflectors are oriented in opposing directions relative to the main flow direction.
