1489119 Flow mixers CREUSOT-LOIRE and E SPRUNCK 11 March 1975 [26 April 1974] 10173/75 Heading B1C [Also in Division B8] Apparatus for maintaining the homogeneity of a fluid flow during division into secondary flows comprises a chamber 2 having symmetry of revolution about a longitudinal axis 3, and having a part-spherical dome 5 into which a single inlet 1 opens laterally, obliquely and tangentially to induce helicoidal flow in the chamber, a truncated conical portion 8 of decreasing cross-section, and a terminal surface 9 concave towards the chamber and having a plurality of outlets 10 symmetrically disposed round the axis 3. There may be twisted vanes 14 to assist the helicoidal flow; the chamber may have an internal abrasion resistant coating 4, and a stopper 6 carrying a replaceable wear-measuring rod 7. The apex half-angle of the portion 8 is preferably 4‹-12‹; as described there are five outlets of which are as on the axis 3; relative flow rates through the outlets are dependant on the areas of the outlets and their angles with the surface 9. The outlets may have convergent or convergentdivergent velosity-increasing portions. The apparatus is especially applicable to a suspension of powder in a gas or liquid and specifically to a suspension of lime in pure oxygen at a density of 2 kg/cnSP3/SP, the gas entering at a pressure of 10 bars.
