SMOKE-CONSUMING- MECHANISM.

Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed October 14, 1912. Serial No. 725,561.

To all whom; it may concern:

Be it known that I, DELMAR D. KELTNER, citizen of the United States of America, and resident of Des Moines, Polk county, Iowa, have invented a new and useful Smoke- .Consuming Mechanism, of which the folprovide improved means for clarifying products of combustion discharged through a draft flue or chimney.

A further object of this invention is to provide improved means for collecting and precipitating heavy matter carried with the products of combustion through a draft flue or chimney.

Afurther object of this invention is to provide improved means for gathering in solution the heavier elements contained in products .of combustion carried through a draft flue or chimney.

My invention consists primarily in means for subjecting products of combustion through centrifugal action to a mechanical separation of the heavier and lighter elements thereof.

My invention consists further in means for subjecting products of combustion to centrifugal action, to combustion, and to a shower bath, to the end of separating the heavier elements from said products, consuming by heat all of the combustible ele- V ments of said products, and taking insolution and precipitating the non-combustible soluble elements.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which Figure 1 is a side elevation of a mechanism embodying my invention. Fig. 2 is a vertical section of the'same. Figs. 3, l and 5 are cross-sections on the indicated lines in Fig. 2.

In the construction of the apparatus as shown the numeral 10 designates a smoke fiue or chimney leading from a furnace, fire box or combustion chamber not shown. A casing 11 is mounted concentric with and extending above the upper end of the chimto the chimney. The casing 11 wholly surrounds. and is of materially greater diameter than the chimney l0 and a containing vessel, tank or retort 12 is mounted be neath said casing surrounding said chimney V and communicates with the casing through a plurality of pipes 13. The tank 12 is provided with a man-hole and closure 14 of common form in one side and also is provided with a discharge pipe 15 preferably leading from the upper portion thereof. It is the function of the tank 12 to re ceive substance in solution drained through the pipes 13 from the casing 11. A ball race 16 is mounted in the lower portion of the casing 11 and is spaced from the wall of said casing and the bottom thereof and also is arranged concentric with the chimney 10.-

A bowl 17 is mounted within the casing 11 concentric with the chimney 10 and said bowl is formed with a ball race 18 on its lower end parallel with the ball race 16 and spaced therefrom by a gang of balls 19. The bowl 17 is open at its lower end and is reticulated or perforated above its center. A ball race 20 is mounted in the casing 11 and is spaced from the top and walls there of and a ball race 21 is formed on the upper end of'the bowl 17 and is separated from said ball race 20 by a gang of balls22. Thus is the bowl 17 mounted for rotation on a vertical axis within the casing 11. A baffle plate 23 or deflector is mounted transversely ofand spaced from the wall of the bowl 17 above and extending across the open upper end of the chimney 10. It is the function of the baffle plate or deflector to arrest theflow of products of combustion from the chimney 10. The upper end portion ofthe bowl 17 may be entirely closed or it may be provided with an aperture such as '24 at its center, said aperture when em- 'ployed serving to discharge clarified gas from the bowl.

A draft flue or chimney 25 communicates with and rises from the upper end portion of the casing 11 and the entrance to said flue is spaced from the upper end of the bowl 17. The casing 11 also is provided with a manhole and closure 26.

The bowl 17 may be rotated by any desired means but for such purpose there is shown a gear-ring 27 on and surrounding the central portion of said bowl, a spur gear 28 meshing with said ring, a shaft 29.n1ounted for rotation in the casing 11 and carrying said spur gear, and a motor 30 outside the casing and adapted to drive said shaft, said motor being shown as carried on a bracket 31 fixed to the casing. It is the function of the rotating bowl to subject the products of combustion 'to centrifugal action to the end of discharging the heavier elements thereof, such as carry pigment or colored matter, centriIugally through the reticulated portion of the bowl and between said bowl and the wall of the casing. Blasts of hot air, flame or other combustion-producing elements may be discharged within the-casing and within the bowl through a plurality of pipes 32 from a source of supply and serve to inflame and ignite the combustible elements of the products of combustion. The tubes 32 preferably extend upwardly within the bowl 1? to points near the upper end of the chimney 10 so that they may discharge into the smoke and products of combustion as the latter pass into the bowl.

An annular perforated pipe 33 is mounted in the upper portion ofthe casing 11 and is supplied with liquid such as water or steam through a pipe 34. It is the function of the'perforated annular pipe 33 to discharge a shower of liquid on the products of combustion within the casing 11 to the end oftaking into solution the non-combustible soluble elements thereof and draining them through the pipes 13 into the tank 12. The clarified gas remaining after the triple action of centrifugal force, ignition and solution is discharged across the pipe 33 and ball race 20 into and through the chimney 25. This is in addition to such clarified gas as may be discharged centrally and axially from the bowl through the hole 2 1.

I do not desire to be understood as limit- 7 ing myself to the construction and arrangement of parts herein set forth as the same may be modified in numerous particulars without departing from thes'pirit of my invention.

I claim as my invention 1. A smoke consuming apparatus, comprising a reticulated bowl mounted for ro-- tation in the path of travel of and adapted to receive products of combustion, spraying means superposed relative to said bowl, igniting means arranged contiguous to said bowl, and a receiving tank adapted to take drainage from said bowl.

2. A smoke consuming apparatus, comprising a reticulated bowl mounted for rotation in the path of travel of and adapted,

to receive products of combustion, a baflie plate transversely of said bowl, spraying means superposed relative to said bowl, drainage means beneath said bowl, and igniting means contiguous to said bowl.

31A smoke consuming apparatus, comprising a reticulated bowl mounted for rotation in the path of travel of and adapted to receive products of combustion, a bafiie plate transversely of said bowl, spraying means superposed relative to said bowl, drainage means beneath said bowl, igniting means contiguous to said bowl, and a casing inclosing said elements. I

4:. In a device of the class described, a smoke stack, a bowl provided with openings in the upper portion of its side walls and with a comparatively larger opening in its upper end receiving the upper end of said stack and extending above and below said upper end, means for imparting rotary. motion to said bowl, means for injecting fresh air into smoke passing from said stack into said bowl, a casing receiving and spaced from the side walls of said bowl, and means for spraying water between said bowl and said casing. I
