c:4v c. CHEVNEY AIR WASHER Filed Octv 9. 1929 CHARLES CCHEYNEY Patented Mar. 8, 1932 UNITED STATES CHARLES C. CHEYNEY, F BUFFALO, NEW 'YORK AIR WASHER Application led October 9, 1929. Serial No. 398,531.

It is well known to those skilled in the art that the most effective way of washing air is to provide wet surfaces over which the air is caused to pass. Heretofore, such washers '5l have been made of stationary scrubber plates which were kept wet by spray roses or water jets. The disadvantages of such a stationarily arranged washer is that numerous nozzles or spray roses with much extra equipment in the nature of piping must be provided, and

the minute orifices of the spray roses or j ets become easily clogged, requiring repairs with attendant interruption of operation. Moreover, such stationary washers require considerable space, as well as a relatively great quantity of water to keep their surfaces Wet.

Furthermore, such devices require pumps and outside mechanism to keep the liquid in circulation. i

It has been an object of my invention to overcome the disadvantages above pointed out, by providing a washer having scrubber plates mounted upon a rotating drum and dipping into a water pan, thereby occupying but relative small space and eliminating the elements which usually cause trouble.

Another object has been to provide a scrubber plate having means for maintaining the surfaces of the plate in a wet condition while they are being rotated from the point where they leave the surface of the water to a point where they are again emersed therein.

Moreover, my device is of such a nature that the air being treated, in passing through the drum, causes the drum to rotate, without the use of any outside means.

Moreover, in my device no water circulating means are necessary since the scrubber plates are moistened by dipping into the water.

Furthermore, my device is of such a nature that the air is caused to pass twice through the scrubber plates, thus greatly increasing tlgeiciency of the device.

The above objects and advantages have been accomplished by the device shown in the accompanying drawings, of which:

Fig. 1 shows-a side, sectional elevation of my complete device.

Fig. 2 is a fragmentary, sectional view, taken on line 2-2 of Fig. 1. f

Fig. 3 is an enlarged, fra entary, sectional view of one of the scru ber plates.

Fig. 4 is a similar view of a modliied form 5,. of scrubber plate.

My device is designed primarily to wash air that is drawn through a heating unit. Such a heating unit is shown in Fig. 1 at 5, and comprises a suitable heating coil 6, through which steam is passed, and a blower 7 which takes air out of the casing 5 through an inlet 8 formed at each side thereof, into the fan casing 9, thence upwardly in the direction of the dotted arrows and through an outlet 10 which projects it into the room being heated. My device is preferably placed below such a heating' unit, as shown in Fig. 1, and comprises a casing 15. The casing may have a solid back wall 16 and an opening 17 formed in its front wall 18. The opening 17 provides an inlet for the air. The wall 18 extends upwardly, thus forming the front of a water tank 19. The height of the wall 18 is preferably somewhat greater than the depth of water contained in the trough. Obviously, if desired, instead of the tank formed by he casing, a separate water pan may be use A washer drum 20 is mounted within the 80 casing 15 and is supported by suitable bearings 21 in which the shaft 22 of the drum rotates. The drum is preferably provided with an end plate 23 at each end thereof to which are secured the ends of the scrubber plates 24. Each of these scrubber plates eX- tends from end to end of the drum, and each has its

longitudinal sides

25 and 26 bent at any suitable angle to each other with the inner apex 27 facing the direction of flow of the air entering the drum, whereby the scrubber plates form buckets or v anes for the air, so that its contact with such buckets or vanes cause the drum to rotate. The side 25 of each scrubber plate is provided with a scupper 28, and the side 26 is provided with a scupper 29. The scupper 28 is formed by a fiange 30 which is arranged so that it occupies a position in respect to the side 25 which is in front of this side when the drum is rotating, and

the scupper 29 is formed by a flange 31 which is so arranged that it occupies a position in respect to the side 26 which is behind this side when the drum is rotating.

A division plate 35 is arranged above the drum and preferably extends forwardly to the front side of the casing at the top of the opening 17, whereby the air will be directed downwardly and caused to pass through the scrubber plates of the drum which are exposed to the opening.

It will be obvious from the foregoing that when the fan 7 is being operated, air will be drawn in through the inlet opening 17 of my device and will be impinged against the trough-shaped scrubber plates 24 and cause the drum to rotate in the direction of the arrow. After the drum is caused to rotate, the scrubber plates will be drawn through the water contained in the tank 19, which will cause their surfaces to be Wet and alsovcause the

scuppers

28 and 29 to be filled with water. rIhe velocity of the incoming air striking against the side 26 of the plate will serve to retain the water within the scupper 29. The air will be defiected between the surfaces of the adjacent platesand caused to enter the center of the drum. After the drum is ro` tated and the side 25 of the scrubber plate 30 reaches a horizontal plane, the water which is held by the scupper 28 carried by this side will be spilled over the outside surface of this side of the scrubber plate and also over the outside surface of the side 26 thereof, thus wetting such surfaces. The air after having entered the center of the drum is caused to move to the opposite side of the drum where it again passes through the scrubber plates. Obviously, the air in coming in contact with the Wet surfaces of the plates is cleaned, such cleaning being more eiicient because of the double passage of the air through the drum. When the plates are rotated still farther, the water carried by the scupper 29 is spilled over the inner surface of the plate, thereby also maintaining this surface in a wet condition.

In some cases, it might be that the air passing through the scrubber plates will carry with it drops of water from the underside of the side 26 of the scrubber plates, and at the outer edges thereof. In many cases such drops of Water would be carried up with the air and be deposited on thel heated surfaces. thereby impairing the heating'v efficiency of such surfaces. In order to avoid the possibility of such entrained water, I have provided an auxiliary scupper 36 attached to the side 25 of each scrubber plate at a point opposite the scupper 28, as shown in Fig. Il. It will be seen that any solid particles of water which would be carried up along the inner surface of the side 25 will be caught by the auxiliary scupper 36 and prevented from leaving the edge of the scrubber plate. This scupper is preferably in the form of a U shaped section which is welded or otherwise secured to the side 25 of the scrubber plate.

While I have referred to water as the liquid for wetting 'the plates, it is obvious that oil or any other liquid suitable for cleaning purposes may be used. In cases where the liquid used is so viscous that the passage of air through the device will not create sufficient power to rotate the drum, it may be necessary to provide some suitable means of positively driving the drum, whichl may be in the nature of any well known and common form of motive power or connectionto the motor which drives the Wheel of the fan. Furthermore, while I have shown the side 25 of the scrubber plate as being provided with a scupper 28 formed by a forwardly turned flange 30, and the side 26 as being provided with a scupper formed with a rearwardly turned flange 31, it is obvious that these flanges may be turned in a number of various directions and somewhat the same results obtained. However, I have found that the arrangement of scuppers shown in Fig. 3 to be the most cthcient. p

These and other modifications of the details herein shown and described may be made without departing from the spirit of my invention or the scope of the appended claims, and I do not, therefore, wish to be limited to the exact embodiment herein shown and described, the form shown being merely a preferred embodiment thereof.
