. T I SMOKE-TREATING APPARATUS.

Application filed July 27, 1921.- Serial No. 488,045.

but such methods are either too costly or.

too inefiicient for general use.

The object of my invention is to avoid the disadvantages referred to and to provide an apparatus adaptable for use with small heating plants as well as larger installations and use a minimum amount of power to produce a substantiallyromplete elimination of the solid matter from the gases resulting from combustion.

Further objects of my invention will appear in the course of the following descrip tion.

To thev accomplishment of the foregoing and related ends, said invention, then; consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexe-d drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however but one of various mechanical forms in which the principleof my invention may be used.

In said annexed drawing Fig. 1 is a diagrammatic view in side clevation of my apparatus applied to a furnace showing the several'units of my construction connected with a vent pipe for the discharge of the treated gases and the outlet for the liquid employed to remove the solid particles;

Fig. 2 is a transverse sectional View of the mixing chambers showing the mixing wheel;

And Fig. 3 is a detail perspective view of one form of spraying device used.

As shown in Fig. l of the drawing, the furnace 1,-shown beneath a steam boiler 2 has fine 3 connected by means of a pass; as t with a 5; ope l iduit '7. into the lower part of a .'.liXi

from a suitable source of power, shown as an electric motor 6, which may also drive the other moving parts of my apparatus. The fan discharges the gases of combustion, crawn from the furnace throu h a condrum 8, within which is rotatablv mounted a shaft 9, ha ing rigidly secured thereto series of mi nheels'lC'. These wheels are shown as of two sizes, the smaller ones alternating with those of larger diameter and permitting clearance for the spray rings or circular pipes 11 arranged transversely at intervals within the interior of the drum. The spray rings are provided. with suitable orifices for the exit of the liquid used to intercept and carry away the solid particles intermingled with the gases. For all ordinary purposes the liquid employed will be water anda supply of the'same is conveyed to the spray rings from a main 12, by a connecting branch pipe 13, having a valve l i conveniently located. The branch pipe enters the mixing chamber near its upper por tion and is connected in turn with each of the spray rings (see Fig.

On the side of the drum opposite that at which the inlet pipe for the furnace gases is located, an outlet conduit 15, for the treated gases is connected, and near a central posiion at the base of the mixing chamber, an outlet pipe 16 for the liquid flowing from the drum is supplied. This last named pipe is provided with a. valve 17 inclined downwardly and discharges into a receiving chamber or tank 18, which is open at the top and may be connected with a sewer or any other final place of discharge. Within the receiving chamber below the point of discharge of the outlet pipe a screen 19 of suitable mesh may be secured to remove from the water such agglomerated matter as is carried away from the mixing chamber.

The outlet conduit for the gases is connected with the mixing chamber near its upper portion, and leads thence to the lower portion of a secondary mixing chamber 21 of substantially the same construction as that of the mixing chamber first described although ordinarily of smaller size. Thus, as shown in Fig. 1 of the drawing, the shaft 9 may be extended longitudinally through the secondary chamber and secured thereto a plurality .1 m shown as of uniform size and more widely spaced than in the first-named drum. The spray rings 23 may be located between alternate pairs of wheels. An inlet pipe 24: provided with a suitable valve, 24, adjacent the upper portions of the drum admits water to the spray rings, and an outlet pipe 25 at the base of the drum permits the water passed therethrongh to reach the receiving chamber 18 above the position of the screen. A valve is provided in the outlet pipe so that the rate of flow through the chamber may be controlled.

An outlet conduit 27 for the gases treated in the secondary chamber is connected near the upper portions of said chamber and leads to a. discharge chamber 28 provided with a vent pipe 29. This discharge chamber may be provided, as shown in Fig. 1, with a nozzle 31 connected with a steam line 32 from the boiler to assist in dissipating any remaining obnoxious qualities of the gases under treatment. An outlet plug at the base of the discharge chamber permits of the removal of any accumulation of liquid or solid matter whenever necessary.

As shown in Fig. 2, the mixing wheels in the first mixing chamber are of two sizes and have broad blades 33, presenting an almost continuous surface when viewed in line with their axes. The blades of the smaller wheels are preferably staggered with respect to the larger wheels.

The operation of the apparatus is apparent from the description. The fan is driven at a speed to secure the desired rate of combustion in the furnace, and the gases discharged into the mixing drum are subjected to a beating action by combined effect of the spray jets and the rapidly revolving wheels. The inlet and discharge valves for the water may be regulated in accordance with the character of the fuel employed and the quantity and quality of the gases to be treated. A residue of liquid may be thus maintained in the base of the drum, when desired, to be agitated by the larger wheels as they rotate. A check valve 3a in the line of the gas inlet pipe will prevent water reaching the fan in the event of accident thereto.

The secondary chamber may not under all circumstances be necessary but experiment has disclosed that with the use of such chamber more perfect elimination may be secured with smaller units and economy of operation thus effected. There is also the advantage of having a different character and degree of treatment of the gases in the two chambers.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mecnanism herein disclosed, provided the means stated by any of the fol lowing claims or the equivalent of such stated means be employed. I

I therefore particularly point out and distinctly claim as my invention 1. An apparatus for treating smoke comprising, a mixing chamber, a plurality of liquid spraying rings located in said mixing chamber and a plurality of different sized mixing wheels rotatably mounted and alternately arranged in said mixing chamber the smaller wheels being adapted for rota tion within the confines of a corresponding number of said rings, the larger of said wheels being adapted for rotation between said rings.

2. In an apparatus of the class described, the combination of a mixing chamber, a driving shaft in said chamber, a laterally extending row of upright spray rings encircling said shaft in said chamber, said rings being spaced apart in an axial direction and adapted inwardly to direct radial streams, mixing wheels on said shaft, a fluid inlet passageway connected with the said mixing chamber adjacent the upper'portion thereof, fluid outlet passageways at the base of said mixing chamber, and means in said inlet and outlet passageways for controlling the amount of liquid maintained in the mixing chamber.

Signed by me this 5th day of July, 1921.
