Abstract

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/cn<SP>3</SP>, the gas entering at a pressure of 10 bars.

Description

The initial flow through the nozzle 2 enters the chamber / where it acquires rotational motion due to the blades of the selected configuration installed inside the chamber and is evenly distributed along the taps 6 with a uniform powder content in all secondary streams.

Claims (2)

Thus, due to the chamber being made in the form of a truncated cone with a smaller base downwards with a source feed supply nozzle obliquely mounted on the side, lids and a bottom with spherical reversed concavity inside the chamber, as well as supplying the cone with blades having an S-shaped configuration and placed between the secondary flow nozzles By making a truncated cone with a taper angle of 4-12, a uniform separation of one main flow, containing the powder in suspension, is achieved. For several secondary streams with the same powder concentration in them as the initial stream. Claims An apparatus for dividing a fluidized stream into several secondary streams, comprising a chamber with a bottom lid, a source feed inlet pipe and secondary stream outlet nozzles, evenly placed on the bottom, characterized in that, in order to ensure an even distribution and uniform separation of secondary streams, the chamber is made in the form of a truncated cone directed by a smaller base with an obliquely installed lateral branch pipe for supplying the initial flow, and the lid and the bottom are made spherical, facing inwards into the chamber. . 2. A device for dividing the fluidized stream into several secondary streams POP.1, from which it is necessary that the truncated cone is equipped with blades that have an S-shaped configuration and are located between branch pipes of the secondary flows, and the truncated cone is made with an angle cones equal to 4-12.
