SMOKE SEPARATOR Filed Oct. :5, 1947 IN V EN TOR.
Patented Mar. 18, 1952 UNITED STATES. PATENT OFFICE 2,589,956 SMOKE SEPARATOR Maxim Panteleiefl, New York, N. Y. Application October 3, 1947, Serial No. 177,611
3 Claims. (Cl. 261-118) My invention relates to a chimney smoke dissipating system, particularly to a smoke separator, and has for its primary object to provide an automatic arrangement for separating combustion particles and the like from gaseous parts of smoke.
Another object of the invention is to provide an arrangement for separating smoke particles only when the concentration of such particles is beyond a predetermined amount.
Still another object of the invention is to provide an improved and simple smoke eliminating device that is readily adapted for mounting on chimneys and smoke stacks.
With the above objectsin View, one embodiment of my invention discloses a chimney in the upper portion of which is placed a smoke particle removing device comprising an outer cylindrical member having a funnel shaped lower element disposed within the chimney and an inner cylindrical member having a conical lower portion penetrating into the funnel for guiding the smoke between the two members. A liquid dispensing pipe having predetermined spaced openings is coiled around the inner member for emitting a fine spray of water under high pressure against the smoke, whereby thesmoke particles are forced into a basin, and carried away with the discharged liquid. The liquid pressure is developed by a pump under control of a smoke volume indicator, so that the device is operative only when required.
A more complete understanding of my invention will be obtained from the following description of a preferred embodiment thereof, taken in conjunction with the accompanying drawing in which:
Fig. 1 shows an elevational view partly in section .of my device adapted for mounting onto a chimney;
Fig. 2 shows a top plan view bringing out more clearly the interconnection between the inner and outer cylindrical members; and
Fig. 3 shows an enlarged sectional view of the pipe bringing out more clearly the spray nozzle.
Referring now to the drawing, particularly to Figs. 1 and 2, there is shown a conventional chimney orsmoke stack I connected to a fuel consuming apparatus, such as a furnace H and the like, the products of combustion of which usually pass up through the chimney and into the atmosphere, which is contaminated thereby.
For eliminating the smoke particles from the products of combustion, generally called smoke, I provide at the upper portion of the chimney In a device I2 comprising an outer shell l3 and an; inner shell Hi,- bothof which are preferably cylindrical. It is understood, of course, that both shells may be of any suitable configuration. However, they should conform to the section of 2 the chimney to which they are to bemounted, that is, if the chimney section is oblong, then the shell sections, particularly the outer section, should likewise be oblong. V At the lowerend of the outer shell I2 is shown a tubular element i5, preferably integral therewith, which conforms in diameter or size to the inner dimension of the chimney l0 within which the element I5 is adapted to be disposed. A conically shaped element I6 is rigidly secured in any suitable. manner, as by a weld H, to the upper end l8 of the tubular element, thereby forming in conjunctionv therewith a funnel for upward passage of the smoke. I w g 7 Between the upper end I8 of the tubular element I 5 and the. outer shell [3 is formed an annular basin or trough i9, which is sloped, as shown in Fig. 1, to concentrate thefluid, as will be described hereinafter, at a lowermost portion 20 thereof. A conduitor pipe 2| is connected to an opening provided inthe portion 20 for delivering the fluid to a sewerage system. To prevent the sewer pip'e 2l from beingblocked a filter (not shown) for intercepting large particles may be placed in the. basin l9. 7
The inner shell I4 is constituted by an open upperend and a,closed, conically shaped lower end with walls 22 that converge. to a. point 23, which is disposed within the conicallyshaped element 5. The walls 22 and element l6 are preferably paranei. Forrigidly securing the inner shell I4 to the outer shell I3, I provide flat braces 24', preferably three at the upper open end: and three adjacent the lower end of the inner shell, each group of three being spaced angularly at and all six. braces beingspaced at 605" intervals. These braces may be secured in any suitablema'nner, such as by welds, to i $3 6 1 t6 b m u i ry st u tu a Around the peripheral surface of the inner shell I4 is shown-coiled a conduit or p pe 25, which is connected to another pipe 26 that is run over the upper portion of the outer shell l3 and thence downwardly to a pump 21, The pipes 25 and 26 may be integral and may be supported to the shells in any suitable manner, brackets 28, shown more clearly in Fig. 2, being adapted for supporting the pipe 26 to the outer shell l3. Similar brackets (not shown) may be employed for supporting the pipe 25 to the inner shell I4. The pump 21 may be of a conventional type adapted for developing a high pressure, the pipe 26 being an outlet pipe and the inlet therefor being shown by pipe 29, which may be connected to a water main or suitable liquid source adapted for use therein. V
The pump 2-1, which may be attached t6 the Smokestack H1 or Placed upon a suitable support (not shown) near the upper end thereof, is preferably operated by electricity, being connected by wires 30, 3| to any suitable power supply 32. Serially disposed in the power supply circuit is shown a smoke volume indicator 33 of conventional type for determining the concentration of smoke particles in the smoke emitted by the furnace II. A photoelectric smoke detecting device similar to that shown in Farmer et al. Patent #2,311,374 of February 16, 1943 may be employed to close or energize the electric supply circuit of pump 21 when the smoke particle concentration is too great. The smoke volume indicator 33 is preferably disposed near the bottom of the smoke stack ID, as shown.
Referring now, particularly to Fig. 3, there is shown a nozzle 34, which is provided upon the outer periphery of the coiled pipe 25. These nozzles 34 are spaced circumferentially at suitable intervals to provide an efficient dispersion of liquid spray. The invention is particularly directed to the fact that a high pressure is provided by the pump 21 to develop a very fine spray through the nozzles 34, which, as shown,'comprise a restricted portion 35 with an expanding rim 3B.
In operation, assuming that the smoke volume indicator 33 discloses a concentration of smoke particles above a predetermined o timal amount,
the electric circuit constituting the leads 30, 3|
the pump 27, which upon developing the proper liquid pressure will cause a very fine spray to be discharged from the pipe 25 through the nozzles 34 upon the smoke passing upwardly.
ney I is separated by the conical portion 22 and is forced to pass between the inner and outer shells and through the spray emitted from the nozzles 34. The liquid spray striking the smoke will dislodge the solid smoke particles therefrom and cause them to be dropped into the basin IS with the liquid, which, in turn, will descend through the pipe 2| for disposition in the sewer,
or as desired.
It will thus be readily apparent that with my invention a substantial portion of the solid particles will be removed from the smoke before it passes into the atmosphere, thereby purifying the air with its beneficial health results to the populace. o -While my invention has been shown and de .scribed .as embodying certain features merely for the purpose of illustration, it is clear to anyone that many modifications are possible without departing from the spirit of the invention and.

a sloping basin in said outer shell for catching the discharged liquid and solid particles, said basin having an outlet at the lowermost portion thereof. MAXIM PANTELEIEFR;
