The invention relates to improvements in the art of separating Various substances from flowing fluids; Such flowing fluids are known as carriers and the term carrier is to be understood as meaning any fluid that' is' directed or kept in motion between given points whether liquid, gaseous or vaporous and whether hot or cold, or a mixture of such fluids; and, the terms foreigmsubstances l and entrained substances as used herein are to be understood as meaning any and all Carrier conveyed substances, whether solid or fluid or both, and whether of less or great er weight than the .Carrier. I

The invention comprises an improved apparatus for utilizin g the forces of kinetic energy, centrifugal motion and gravity to separate or remove entrained substances from Carrier fluids'.

The invention may be readily understood on reference to the accompanying drawings, in which Fig. 1 is a vertical section of a dust Collector, both embodying and illustrating this invention; Fig. 2 is a plan View thereof on the line 2-2 of Fig. 1; Fig. 3 is a Vertical section illustrating an operation ofthe invention wherein the incoming stream is set into rotation before it'is subjected to the separating Operation within the body of the separator; and Fig. 4 is a sectional view on the line l- 4: of Fig. 3. i

Referringto Fig s. 1 and 2, 2 represents the 1nlet pipe through which the burdened carrier enters the separator. This pipe and the 'body of the separator are coaxial upon a Verr tical axis.' Thebody 3 of the separator is of considerable depth, usually terminating in a hopper 3' and a drain spout 3". The body 3, 'may be rectangular or circular: as here shown. The top 4 thereof containsalarge opening 5, from which the collar 6 rises. This' collar may be cylindrical, butpreferably'is hereinafter explained, The

as the space ll, within the body 3, is called' the accumulation space of the separator. The operation of the apparatus shown in lFigs. 1

' and 2 is as follows: v

The direction arrows in Fig. 1 represent the movement of the difierent parts of the Carrier stream outward and downward into.

the separating space A and as indicated the fluid having discharged its burden of foreign substances and having been completely or largely deprived of its energy attains practically a static pressure condition in the central parts of the accumulation space B.. From that position the unburdened Carrier fluid may escape from the separator only by way of the space A andthe annular passage 7; that is, the unburdened 'Carrier is forced to find its way out through the incoming stream of burdened carrier fluid. Thus the final filtration of the fluid is ensured, the entering stream serving as the filtering medium therefor:

Flowing downward from the pipe 2 the burdened carrierencounters 'the' conical defiector 9 and is thereby expanded into an um brella-like stream which persists in its move ment until interrupted by the collar 6. The centrifugal separation is initiated at that moment and is accentuated by the immediate effort of the Carrier fluid to turn within it- A self and. escape upwardly. The gravity separation proceeds normally at all times. The radial plates 10 successfully defeat inequalities in the stream from the pipe 2 and also defeat the tendency of the particles to defiect laterally within the space A as contrasted with the described general downward or longitudinally of the particles therein. It is to be noted that. the effective cross-sectional loo area of the separating space A is several times that of the pipe 2 and the opening'7, this being a prerequisite to the persisting downward movement of the burdened carrier Within the collar 6.

The structure of Figs. 3 and 4 eXhibits a tangential or whirl-producing tuyre 11 (having a closed top 11') as a means for promoting a Whirling condition in the carrier fluid descending through the pipe 2 The carrier fluid enters the tuyere from the housing 12 and pipe connection 12', supported at a distance above the to of the separating Collar 6 The lower en of the pipe 2 may be fiared outwardl as shown in Fig. 3 or may be straight. t closely approach es the suitably supported spreading cone or defiector 9". The action of the separator is as before described except to the extent that it is modified by the initial separation of the dust particles within the tuyre 11 and the spiral downward movement that the tuyere imparts thereto Within the pipe 2 A The initial separation accomplished by the centrifugal tuyre 11 obviously has the effect of preliminarily Collecting or massing the dust particles against the inner side of the pipe 2, so that they are thrown outward at the lower end of the pipe, and are more certain to be projected against the Collar 6 and to be whirled downward by the carrier stream crossing the separating chamber A.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The herein described process of separation that consists in projecting a burdened carrier stream downward, at one point deflecting said stream laterally and thence downward and thence inward, throughout the circumference of the stream, Collecting the separated foreign substances, and, releasingthe unburdened carrier fluid outward through the first deflected portion of the burdened stream.

2. The separator herein described comprising a separator body having a dischar e opening at the bottom for the foreign su stances, in combination with an annular separating chamber erected on the top of said body and in open communication therewith, said chamber being o en at the top and forming the outlet of t e separator, a defiecting cone centrally positioned in said chamber, a burdened carrier inlet pipe descending vertically nearly to said cone and coaxial therewith, and a plurality of laminating plates radially positioned in said separating chamber, substantially as described.

In testimony whereof I have hereunto set my hand this 26th day of June, A. D. 1926. CHARLES a GILBERT HAWLEY.
