STATES PATENT OFFICE DANIEL PERRIER, F UNI E'U'X, FRANCE, ASSIGNOR 0F ONE-HALF T0 SOCIETE ANONYME FRANCAISE D'ITE: COMPAGNIE INDUSTRIELLE DES MOTEURS A EXPLO- SIONS C. I. M. 11., OF PARIS, FRANCE CENTRIFUGAL SEPARAIOR Original application filed January 23, 1928, Serial No. 248,945, and in Germany January 22, 1927. Divided and this application filed November 15, 1928. Serial No. 319,644.
liquid (or gaseous fluid) to be treated is suhj ected during its path through the apparatus,
twice, three times or a numberof times which may be practically as large as desired, to the same centrifugal forces as that developed in the outer annular chamber. I Various embodiments of the improved centrifugal separator forming the subject of the invention are illustrated diagrammatically and simply by way of example in the accompanying drawing.
In this drawing Fig. 1 illustrates a first embodiment of a separator according to the invention in which an equal centrifugal force is obtained in two adjacent chambers. 4
Fig. 2 illustrates another embodiment according to the invention in which an equal centrifugal force is obtained in four annular chambers but in which the volume reserved for the heavy solid sediments to be sparated from the liquid or gaseous fluid is increased.
According to the invention the rotary distributor is formed by a series of concentric ribs 1, 2, 3, 4 and 5 inclined to the general axis of the apparatus at an angle 0: which varies essentially according to the results to be obtained. These ribs form cone frustums which are assembled by their large bases with other ribs 6, 7, 8, 9 and 10 also inclined to the general axis of the apparatus at an angle B which will generally be equal to the angle a; but this is not an essential feature of the invention, and the angles on and ,8 may be different.
The inclined ribs 2 and 4 are open at their ends in the neighbourhood of the small bases of the cone frustums so that the annular chambers 11 and 12, 13 and 14 communicate with each other at their upper parts. Similargly, the ribs 8 and 10 are open at their ends located in the neighbourhood of the small bases of the cone frustums so that the annular chambers 12 and 13, 14 and 15, communicate with each other at their lower parts.
If the liquid or the gaseous fluid to be treated contains no other liquid or gaseous element which it is desired to remove these orifices 17 willbe closed. Their arrangement may, moreover, be different. In the embodiment shown in 2 they are pierced upon the inclined "rib 1 in the neighbourhood of thelargejr base of the cone frustum, that is to say in the zone in which the centrifugal force is a maximum. y
The operation of the apparatus is then as follows a The liquid or the gaseous fluid to be treated enters'thro'ugh a duct 19 and penetratesinto a distributing chamber 20in which it under,- goes a first separation, the. most dense solid element being deposited upon the outer wall of this chamber.
The liquid (or gaseous fluid) then enters the chamber 11 through the orifices 16. A eparation by order of density is produced in this chamber. The solid elements which are the heaviest become deposited in the part of the chamber where the centrifugal force is maximum, that is to say, in the zone near the arge assembly base of the ribs 6 and 1, the heavy liquid elements (or gaseous) remaining along the inner wall of the rib 1 in order to pass out through theorifices 17.
The remainder of the liquid (or of the gaseous fluid) then enters the chamber 12 in which it undergoes a new separation, and so on in the chambers 13 and 14. It then entersthe chamber 15 in which it may again undergo a last separation. It is then collected through the orifices'18.
As will be seen, the liquid to be treated is subjected in its passage through the rotary distributor toan equal centrifugal force in four different annular chambers (cases shown in Figs. 2 and 3). In the zones ab and 5: of the chamber 11; be and i of the chainr 12; 0d and cf of the chamber 13; de of the chamber 14. Similarly, an equal centrifugal force is obtained in the zones ij and 01) of the chamber 12, jh and no of the chamber 13, kl and ma 'of the chamber 14, lm of the central chamber 15. i
The rotary distributor shown in the accompanying drawing with five concentric ribs may also be constructed according to the invention with any number of ribs." i
What I claim is:
1. In a centrifugal separator, a rotary distributor, comprising a casing, upper and lower concentrically arranged assemblages of batfles of frusto'conical form within said casing, the corresponding baflies' or the two assemblages being connected to each other at their major ends, relatively adjacent bafiles defining, between them,' circulation chambers concentrically arranged and concentric to the axis of rotation of the distributor, the said baffles being arranged alternately with respect to one another, to establish communication between said chamhers, means for admitting the fluid to be separated into the casing at one point for delivery into the outermost one of said chamhas, means arranged substantially at' the goint of greatest centrifugal force for conuct ngthe heavier of the separated fluids from said distributor, and means for conducting the refined from the distributor at a eg p i l. h
"QlIn aceiitrifugal separator, a rotary distributor, comprising a casing, upper andl owercoiicentric*a1ly' arranged assemblages of Bafl ies of'frusto-conicaI form within said casthe'correspondi'ng baflies of the two as blages being connected to each other at their major ends, relatively adjacent baffles defining, between them, circulation chambers concentrically arranged and concentric to the axis of rotation of the distributor, the said battles being arranged alternately with re spect to one another, to establish communica' tion between said chambers, means for admitting the fluid to be separated into the easing at one point for delivery into the outermost one of said chambers, the outermost one of said upper assemblages of battles having a plurality of openings therein for conducting the heavier of the separated fluids from said distributor, and means for conducting the refined fluid from said distributor at another point.
3. In a centrifugal separator, a rotary distributor, comprising a casing, upper and lower concentrically arranged assemblages of bafiles of frusto-conical form within said casing, the coresponding bafiies of the two assemblages being connected to each other at their major ends, relatively adjacent baflles defining, between them, circulation chambers concentrically arranged and concentric to the axis of rotation of the distributor, the said baffles being arranged alternately with re spect to one another, to establish communication between said chambers, means for admitting the fluid to be separated into the casing at one point for delivery into the outermost one of said chambers, the outermost ones of said upper assemblages of battles having a plurality of openings therein arranged close- 1y adjacent the point of greatest centrifugal force, for conducting the heavier of the separated liquids from the distributor and means for conducting the refined fluid from the distributor at another point.
In testimony whereof I have signed my name to this specification.
DANIEL PERRIER.
