Abstract:
1. A device allowing the separation of particles of solid with a diameter in the range of 10 to 100 microns, dispersed in the form of a suspension in a liquid, said device comprising an upper portion which is cylindrical in shape with a ratio H/D in the range of 2 to 6, and a lower conical portion having the same maximum diameter as the cylindrical portion, the cone angle being in the range of 40° to 60°, said device further comprising: a tube (Ta) for admitting the suspension in the form of an elbow, the horizontal portion of said elbow, with diameter (d an upper withdrawal tube (Ts) for clear liquid located at the top of the upper cylindrical portion; a lower withdrawal tube (Ti) for solid particles located at the bottom of the lower conical portion; and an internal baffle (B) making an angle (β) with respect to the vertical, which is substantially equal to the cone half angle (α) of the lower portion of the device, is fixed to the internal wall of the cylindrical portion of the device, at a level substantially identical to the level of the start of the vertical portion of the admission tube (Ta), the height of said baffle (B) being in the range of 0.4 to 0.6 times the height of the vertical portion of the admission tube (hb).
