Method and device for static mixture combining a helical movement of the constituents of which has a deviation of the liquid flow and a reduction of the passage section

摘要

Static mixer comprising a cylindrical body 1 equipped at a first end with entries 2-3 for tangential injection of the constituents to be mixed, a tubular helix 6 arranged inside the said body without contact with its wall and coaxial with the latter and forming, on the side of the said first end, an axial exit 5 for the mixture and with a bottom 4 which closes the said body at its second end and forms, facing the corresponding end of the helix, concave surfaces 41 for returning the liquid streams towards the inner channel of the helix.
