SEPARATOR Filed Aug. 14, 1959 INVENToR. Je-PH Pfam/da ilnite hlifill Fatt-interi Nov. 20, 1952 3,664,411 SEPARATGR .ioseph Breslove, Jr., Commonwealth Bldg., Pittsburgh 22, Pa. Filed Aug. 14, 1959, Ser. No. 833,734 4 Claims. (Cl. 55-457) This invention relates to the art of separating solids from iluids in which the solids are entrained and more particularly relates to an improved means for etiiciently separating solid particles from gases such, for instance, as the removal of cinders and fly ash from boiler iiue gas or the removal of impurities, such as finely divided particles in exhaust systems and the like. I
This invention, furthermore, is an improvement 1n structures, for instance, such as are disclosed, described and claimed in my Patent No. 2,487,633, granted Nov. S, 1949 wherein an axially moving high rotational velocity stream of uid carrying entrained materials is caused to pass between axially aligned spaced apart conduits, thus permitting entrained particles to be thrown out of the stream tangentially through the space and into the receiver chamber.
'It is one of the objects of the present invention to produce a high rotational velocity in an axially moving gas stream in which particles of material, such as ily ash or other solids are entrained and to provide means of separating the entrained material, including the minutest particles, from the rotating stream with a very high degree of eticiency.
Another object of the invention is to overcome the reentrainment of particles after they have been separated from the main axially moving stream rotating at high velocity and to direct the separated material to a collector.
Another object of this invention is to provide, in a straight-through cyclone separator construction, whether or not of the regenerative design, a receiver for the separated materials which includes an outer Wall or cylinder spaced radially from the axially moving column of entrainment forming a closed compartment concentric with the axis of the high rotational velocity stream in which means is provided to limit the volume of such compartment outside the high velocity section of the device and inside the concentric wall defining the receiver.
A still further object of the invention is a construction of the type described whereby the axially moving and rotating gas stream will impart a secondary circulation of rotating gas within the receiver in such manner that this outer body of rotating gas Will circulate in the axial direction of the main stream passing axially through the separator where it is close to the main stream and in the opposite axial direction near the outer wall or shell of the receiver concentrically spaced from the main stream.
A still further object of the invention is a device of the type dened in which the circulation of the outer or secondary gas stream Within the receiver is such that it will meet a higher resistance in the area located at the upstream end of the receiver and a lower resistance in the area of the receiver at the downstream end or the receiver.
Another object consists in the application of simple means in the concentric receiver chamber whereby the secondary circulation of fluid and entrained particles in the chamber which were separated from the main axial moving rotating stream, is coniined and maintained in the chamber in such relative axial position with respect to the axial movement of the main stream passing between spaced apart sections of the conduit carrying the same that such secondary circulation will encounter a higher resistance in the chamber at its upstream end, and a lower resistance in the downstream end of the chamber.
Another object is to provide a barrier or end wall deiining the end of the receiving chamber which is in closer proximity to the end of the conduit section defining the upstream portion of the device than the end wall of the chamber which surrounds the spaced end of the conduit section deiining the downstream portion of the device.
Another object is to eliminate the formation of objectionable eddies in the chamber.
A still further object is a device of the kind disclosed which is highly eiiicient over a wide range of flow rates.
Other objects and advantages of this invention will become more apparent as the following description of an embodiment thereof progresses, reference being made to the accompanying drawing in which like reference characters are employed to designate like parts throughout the same.
In the drawings:
FIGURE l is a side view of an apparatus embodying my present invention in which the outer shell and other parts are broken away to illustrate the internal construction of the device, the arrows indicating the direction of movement of the stream containing the entrained material;
l FIGURE 2 is a transverse section taken on line 2-2 ot FIGURE l; and
FIGURE 3 is a view in diagrammatic form of a simplified version of the invention as applied to a straightthrough type of separator.
The present invention resides in a relatively simple improvement over the type of apparatus illustrated in my Patent No. 2,487,633, granted Nov. 8, 1949 and is particularly adapted to be applied to separators of the straight-through type in which a fluid containing entrainment of particles, such as ily ash or the like, is caused to move in an axial stream through the apparatus at a high rotational velocity and to bridge a gap or space within the apparatus along the path of travel of the stream and through which particles are ejected or dis-entrained in a substantially tangential direction into an outer chamber which is in axial alignment with the axially moving stream. The particles thus dis-entrained into this chamber are eventually collected in a receiver and disposed of.
The present invention constitutes a distinct improvement in the art in that the eiciency of separation is greatly increased due to its ability to separate the very fine particles which, in former devices of this type, have become re-entrained in the axially moving stream because of the presence of undesirable eddy currents or turbulence in the receiving chamber and around the exposed portions of the stream passing through the adjacent spaced ends of the conduits through which the stream is passing.
The drawing illustrates in both practical and diagrammatic form the application of the present invention to a device of the kind disclosed. The apparatus shown in FIGURE l is of the type illustrated in my Patent No. 2,487,633 and its construction and operation is fully disclosed in said patent. However, the application of the present improvement to such a structure may be described as follows:
As illustrated in FIG. l and as disclosed in my Patent No. 2,487,633, the particle or impurity laden iluid column is caused to move axially in the direction of the arrows entering the separator unit A through the tube 1 to the right of the figure.
High rotational velocity is imparted to the axially movying fluid column by suitable means in the unit A, such as shown in my Patent No. 2,487,633, and as this column Vpasses through the tube or cylinder portion 2 of the unit at high rotational velocity, it bridges the space or gap 3 4between the end of the cylinder 2 and the adjacent end of the -axially aligned cylinder 4 in unit B. The cylinder 4 communicates the fluid column with means in the unit B to reduce the rotational velocity and nally impart an axial substantially non-rotational ilow to the unladen fluid column discharged through the conduit 5.
An outer shell 6, constituting a receiver for particles and other solids separated from the laden fluid, houses the cylinders 2 and 4 and is closed to the`outside atmosphere. This shell is concentric with and is spaced from the cylinders 2 and 4 sufficiently to provide an annular chamber 7 between the shell inner surface and the cylinders 2 and 4, into which particles are discharged substantially tangentially from the axially moving rotating uid column as it passes from cylinder 2 into cylinder 4 across the gap 3.
As the whirling iluid body or column enters the cylinder 2 it is rotating at high velocities. Under such conditions, the heavier particles entrained in the whirling'column are caused to run along the inner surfaces of the cylinder wall of the member 2 land as the fluid column advances to the left, as in FIG. l, they are finally discharged substantially tangentially over the free endof the cylinder into the chamber 7. In addition, these heavier particles will be followed or mixed with'the lighter particles which are also separated from the whirling fluid body and, as the Irotating column moves axially, these particles too will be discharged substantially tangentially of the. column into the chamber 7 as the column passes across the gap or space 3` lbetween the cylinders 2 and 4.
Referring now more particularly to FIG. 3, it will be seen that arsecondary circulation is Vset up in the chamber '7 which is indicated generally by the arrows 8, this circulation representing the general movement of the ejected particles as they pass into the chamber 7.
The secondary circulation is confined within the annular chamber 7 which surrounds the end portions of the cylinders 2 and 4V and the axial space or gap 3 therebetween. Since the fluid column entering the cylinder 2 from the right in FIG. 3 is moving axially to the -left at a substantially uniform rate, and since its rotational velocity is high and in the direction indicated by the directional arrows 9, the secondary circulation set up in the chamber 7 will move in clockwise direction, as viewed at the top of FIG. 3, and, of course, will move -in a counter clockwise direction, as viewed at the bottom of FIG. 3. Those areas of the circulation lying close to the outer surface of the exposed portions of the cylinders 2 and 4 Will move in the direction of the axially movingruid column passing through the cylinder 2 and 4, while the areas of the secondary circulation running along the inner surface of the chamber 7 will, of course, be in an opposite direction.
The secondary circulation will, due Vto Vthe high rotational velocity of the column passing from cylinder 2 to cylinder 4 be caused to rotate in the direction 'of rotation of the column, as indicated by the arrows 10, this rotation being vabout the axis of the rotating column'but within the chamber 7. Y
I have discovered that this secondary circulation Ymay be so controlled that it will notV only produce amore complete separation of entrained particles from the fluid column, Yincluding those of extremely minute size, but will substantially prevent and eliminate re-entrainment of particles in the ud column once they haveV been separated therefrom and delivered to the chamber 7.
-According to my invention, I provide a very Ysimple means for obtaining this control. It will be noted that the secondaryr'chamber 7 lies across the gap 3 separating the adjacent ends of the tubes 2 and 4 and is concentric with the common axis passing along the tubes 2 and 4. It will also be noted in FIG. 3 that the chamber 7 overlies this endof the tube 2, through which high velocity laden column passes, for a greater distance than that which overlies the adjacent end of the tube 4 and that kthis relationship extends circumferentially around the tube ends.
An end Wall 11 defines the longitudinal limit of the secondary chamber 7 at one end while the end wall `or bafe 12 defines the longitudinal limit of the chamber atV its opposite end. Since the end wall or bafe 12 is located closely adjacent the inner end 13 of the tube 4 and the Vend wall 11 is located relatively remote from the inner end 14 of the tube 2, a condition is created in the chamber 7 which offers less resistance to the rotation of the uid in the chamber at the left hand end, as illustrated in FIG. 3, adjacent the baffle 12, than the resistance which -is encountered by the fluid at the right hand end adjacent the Wall or baffle 11 as it continues its rotation Within the chamber 7 in the direction of the arrows 8. By this arrangement, such eddy currents as are produced yand encountered in the rotating uid in the chamber 7 are desirable andtbenecial in the control, efliciency and completeness of separation of particles from the uid because, for example, the eddy currents indicated at 15 occurring at the left end of the chamber 7 adjacent the bathe 12 oier very little resistance to the circulation at the downstream end of the chamber, while the eddy currents, indicated at 16 and occurring at the opposite or upstream end adjacent the end wall 11, oier materially greater resistance to the circulation. The resultant slight differential pressure Vset up produces a highly eiicient circulation in the chamber 7 and consequently assures separation of iine particles, as well as the heavier entrainment materials, while preventing reentry into the main high velocity rotational stream passing through the separator.
The separated matter may be collected in a receiver or hopper indicated generally at 20. As the particles, sepai rated from the main stream, move with the rotating fluid in the secondary chamber, as illustrated by the arrows 1% in FlG. 2, they will be discharged by gravity through an elongated opening 21 formed in the wall 6 and will pass into the hopper which surrounds this opening and closes it off from the outside atmosphere. beingairtight permits circulation of fluid current into and Vout of the space or opening V21 and also permits the solids,
to settle .in the hopper. A sealed connection conduit 22 may lead to a valved outlet through which the collected material may be discharged, without interference with withintthe casing and concentrically spaced from saidA outer casing, a pair of annular end walls separating said conduits from said casing and forming between them a chamber communicating with the space between said conduits and receiving particles separated from said rotating laden fluid stream as it passes from one of the alignedV conduitsto the other aligned conduit, said outer casing Y having a particle discharge opening, Vand collector means communicating with said discharge openingV to receive particles dischargedrfrom said chamber, said chamber constituting an enclosure in which the particles separatedV from the said uid stream are deposited in anV eddy How and caused to travel Vboth circumferentially and axially exteriorly of the laden uid stream, one of the annular end wallsV of the chamber being located in close prox- Y irriity to the inner end of one of the spaced aparttaligned conduits in theV casing andthe other annular end wall being located remote from the inner end of theV other spaced apart aligned conduit in the-casing thereby to substantially eliminate the formation of an eddy ilowVL in the downstream end of the chamber and opposed'to said other eddy how.
