7 Claims.
This invention relates to new and useful iinprovements in apparatus for' separating foreign particles from a gaseous stream in which they are carried.- I I I I II I I An object of theinvention is to provide an efiicient apparatus of simple and rugged construc-' tion.
Another object is to provide a separator which is particularly adapted for cooperation with the boiler or heating apparatus of a power plant, for
example- W Another object is to provide an apparatus for collecting the fQreign par t icIes carried in the gaseous stream and removing them therefrom.
The invention consist's in the cooperative arrangement and combination of parts to be more fully described hereinafter and the novelty of which will be particularly pointed out and distinctly claimed.
In the accompanying drawings, to be taken as a part of this specification; there are fully and clearly illustrated several preferred embodiments of the invention in which drawings:
Figure 1 is a view in front elevation of a power unit such as an industrial boiler having inter calated in the stack a separator or cinder collector, II
Fig- 2 is a detail side elevation; looking from right to left of Fig} l; of the cinder collector.
Fig. 3 is a detail side elevation, looking from left to right of Fig; 1, of the cinder collector, I
Fig. 4 is a view in section on the line 4-4 of Fig. 2 but showing aportion of the boiler and of the stack, I
Fig. 5 is a plan view of the interior of the collector with an outlet plate or tube sheet removed,
Fig. 6 is a view in vertical section through the collector, generally similar to that of Fig 4,
I Fig. 7 is a detailed view in section on the line 1-1 of Fig. 6 and looking in-the direction of the arrows, and I Fig. 8 is a diagrammatic view of a separator or collector showing the invention.
Referring to th drawings by characters of reference, the numeral l indicates generally a boiler or furnace such as might be employed in industrial power apparatus and which has a chimney stack or outlet flue 2 for the producing of combustion. The stack includes a portion 3 intercalated between the chimney and the boiler I, this portionbeing a casing of generally truncated triangular form in front elevation as seen in Fig 1- and of generally rectangular form in plan view as seen in Fig. 5. Theboiler flue outlet 4;see Fig. 4, discharges upwardly into the casing into a 2 space 5 aving upwardly inclined converging walls 6, 1 forming the roof or the chamb r 5 and separating the chamber 5 from laterally r ds'i; honed cinder collecting chambers a, 9. twm be apparent that the upper wall or roof of the chambers might be formed by" a single inclined wan or that there might be more thantwb walls;
converging up ardly and joined at their marginal side edges. The collecting chamber a discharges:
downward through a chute or duct I'll which may be divided as seen' m Fig. 3f and have" we outlets" which feed nto a closed hopperli, a portion only of which is shown. The chamber 9 likewise discharges through a chut or duct l3 which feed through an outlet l4, see Fig. 4.1m a closed bin or hopper l5, apart on y of which is shown. It may be noted that the lower portion of the easing 3 has upward diverging front and rearf'walls I6, I! to accommodate the enlarged cross section of the upper casing portion containing the chairibers 8 and9. I I I I I The casing 3 is made u'pof a plurality of identi calupper sectio s or portions l8}; l9 and each of which contains th inclined. roof walls 6, i and a pair cfspaced collecting chambers similar to thecha'nibers'd and 9, these sections being sepa rated from each other by partition walls 2|, 22 extehdmgverncany rrbm side" to side f the toner l. Thesesec'tion' s l8, isalnd'idisch rge into a hood or the'lik'e 3' which is tapered to join the chimey st'ack 2. The sections 18, I 9 and 20 being similar: to each other a description of one will sufiice for all. I I
The walls Sand 1 each have a plurality of equispaeed elliptical apertures 24 therethrough whichar' rowsat right angles to each other. Extend ing downward through each of the apertures 24; and sealed therein there is a tube or conduit 25 extending vertically upward and each of which terminates slightlybelow the walls 6 and 1 andwithin the chamber 5. The upper ends of the tube 25 terminate ina substantially common hor'- izontal plane so that the tubes 25 are of varying lengths, decreasing toward the center line of the chamber 5. The upper ends of the tubes 25are' rigidly supported by a grill work or grid formed by bars 26 extending radially from and joining the tubes to each other and to the side walls of the casing 3. These bars may be secured in position by welding or the like. In the upper outlet end' portion of each of the tubes 25 there is a gas ro tating' means or spinner 2"! which serves to direct the outlet flue gases into a predetermined en'- nular path. Each spinner has a central cylin d'rical body portion" 28 concentric with its re- 3 spective tube and which supports spiral vanes 29 which cause the rotation of the gas stream so that the particles of foreign material such as cinders in the flue gases are impelled laterally or radially outward toward the side walls of the tubes 25.
The casing 5 has a top wall having a plurality of apertures therethrough alined one with each of the tubes 25 and each containing a conduit or tube member 3| which projects downward but terminates short of and in spaced relation above its alined tube or conduit 25. The tubes 3| are each of smaller flow area or diameter than the tubes 25 and these tubes each have their geometrical individual elements positioned substantially parallel to each other so that the walls of the tubes 3| and 25 are parallel to each other. Each of the tubes or conduits 3| is separated from the other by shield or partition members 32 in theform of a grid, see Fig. '7, which are welded or otherwise rigidly secured to the underface of the top wall or plate 30. These shield members 32 extend downward below the outlet ends of the tubes 25 and provide a pocket or recess 33 around each of the tubes 3|. The shield members 32 are also spaced laterally from the tubes 25 as at 34 to provide a down flow space for discharge of the cinders or foreign particles carried in the outlet flue gases. It may be noted that in a practical commercial installation, solely for purposes of illustration, with a casing section as l9 having horizontal dimensions of say 5 x 11 feet, the conduits 25 might have an internal diameter of substantially 8 inches and the conduits 3| an internal diameter of about 6 inches, the spinner cylinder 28 being of about 4 inches diameter.
In the operation of this separator or collector it will be apparent that an induced draft fan may be employed for combustion air or flue gas exhaust and also when the furnace or boiler is under natural or forced draft that the flue gases containing particles of foreign material such as the cinders will discharge upward into the chamber 5. The main gas stream in the chamber 5 will be split into branch gas streams fiowing upwardly through the tubes 25 from below the walls 6 and 1. These gas streams will be directed into predetermined annular paths by the central cylindrical portions 28 of the deflecting members 2? and this annular stream will be caused to whirl or rotate by the spinner blades or fins 29. In addition to the conduits 3| being of less diameter than the conduits 25 and such that the cylindrical portions 21 cause the annular stream to discharge into the pockets or cells 33 and not directly into the conduits 3|, there is also the lateral or-radial discharge of the cinder particles toward the side walls of the conduits 25 so that these particles discharging from the tubes 25 will be prevented from direct flow through the top plate or wall apertures by the depending portions of the conduits 3|. The foreign particles or cinders collecting in the pockets 33 will be thrown out of the air stream and will fall by gravity through the annular channels or passageways 34 which surround the upper ends of the tubes 25 and will deposit on the upper inclined faces of the walls 6 and thence flowing by gravity down the wall surfaces and through the duct members l0 and I3 into the collecting bins or hoppers l2 and 5. The cleaned gases will discharge upward through the conduits 3| into the hood 23 and thence flow to atmosphere through the chimney stack.
It is also contemplated that the walls 6, 1
4 might converge downward so as to form a V-shaped trough which would be accomplished by mere transposition of the portion of the collector of the vertical plane of the wall I to a position at the left of the portion of the vertical plane of the wall 6 as viewed in Fig. 6.
Referring to Fig. 3, it is a diagrammatic illustration of the above described separator in somewhat diiferent form or arrangement of parts. Here the boiler or furnace is designated 55 and is contained Within a housing or casing 5| of which the lower portion 52 forms a bin or collecting chamber having a clean-out door 53. The upper wall 54 of the combustion chamber of the furnace has an outward and downward inclined surface so that the cinders or foreign particles falling thereupon will flow therefrom into the bin 52. The furnace 50 has a combustion gas outlet flue or conduit 55 opening upwardly from the combustion chamber through the wall 54. The conduit 55 contains a gas rotating means or spinner 58 positioned substantially in the outlet end portion of the conduit 55 and which throws or whirls the discharging gases into a predetermined annular path. The spinner 56 also causes the foreign cinder particles to discharge radially or laterally into the outer annular portion of the discharging gas stream such that these particles will be directed into the annular recess or pocket 51 formed between the conduit or tube 58 and the cylindrical shield member 59. The conduit 58 projects up ward through and is sealed in the top casing wall 68 and leads to or forms part of the usual chimney stack. The shield member 59 which is sealed to and descends from the inner surface of the top wall 60 extends downward around the conduit '55 in spaced relation thereto to provide an annular flow passageway 6| for the discharge of the cinder particles into the bin 52.
The operation of this form of the invention will be apparent from the foregoing description of this Fig. 8 taken in connection with the foregoing description of the invention as shown in 7 Figs. 1 to 7 inclusive.
What is claimed and is desired to be secured by Letters Patent of the United States is:
1. Apparatus for separating particles of material from a gaseous stream in which they are carried, comprising a casing defining a chimney stack portion, upward converging inclined walls separating said casing internally into an inlet chamber and laterally spaced particle collecting chambers, a plurality of closely adjacent vertical conduits extending through said walls and terminating at their lower ends adjacent said walls and at their upper ends substantially in a horizontal plane, grid bar means extending across said casing and rigidly supporting the upper ends of said conduits, spinner members, one spinner member being positioned in the outlet end portion of each conduit, a top wall On said casing, a plurality of outlet conduits extending through and sealed in said top wall, said outlet conduits being alined one with each of said first-named conduits and terminating at their inlet ends above said first-named conduits, and vertically positioned wall members extending downward from said top wall and terminating above said inclined walls, said vertical wall members being laterally spaced from and surrounding said firstnamed and said second-named conduits to provide a separating chamber around each of said outlet conduits and a downfiow passageway around each of said first-named conduits,
