This invention relates to a device for unidistributing a liquid over a given formly area and more particularly to a spattering means used in conjunction with a spray nozzle.

The device must be capable of'being easily rodded out in case of stoppage and must be rugged and rigid to prevent distortion while rodding.

as heavy iron, aluminum or acid-proof bronze,

or acid-resisting mater al such ashard rubher. If desired, metals coated with acid-re sisting materials may be employed.

The spattering means which is the subject 1 of this invention fulfills the above requirements. When a particle of liquid strikes a plate of ordinary construction, it

leave the plate along a tangent to of impingement. Therespatter tends to the plate at the point fore, with a plate. having a surface of large radius of curvature, the liquid will be thrown ofi in a nearly horizontal direction and must depend upon gravity for the downward motion. 7

Hence, if liquid velocity, the llOIlZOIltiLl velocity component will be high compared with the vertical com- I ponent and theliquid will tend to strike the An object of this invention is to provide found that in order to obtain j the desired results, a device for the above will be sprayed uniformly over a given 1 Furthermore, the spattering means must have no restricted sections wh ch To resist the effect of corrosion, all the parts are preferably made of metal such strikes the plate at a high sides of the tower before it reachesthetower packing. However, when a spatter means is used having a surface with a small radius of curvature as, for example, a small ball, the

tangent at the point of impingement is more :nearly vertical, which makes the influence of gravity relatively less and the total deflection of the particle more nearly independent of the velocity of the stream orrate of flow. With a ball ofgiven size,even if the size of the nozzle is increased slightly, the outside of the larger stream strikes the ball at a point where the tangent'is still more nearly vertical and the deflection f the liquid is affected correspondingly less.

In :the use of ordinaryspatter plates, a

"considerable area beneath the plate receives no solution'but must depend upon adjacent sprays to supply the solution. With a spatter means of substantially spherical shape, the

combined effect of adhesionand surface tension of the liquid sprayed, or in otherwords, cap1llarity,'causes a part of the solution to follow the surface to the underside and be distributed upon the area directly beneath.

" In theaccompanying drawing:

Figure 1 is a View, partly in elevation and partly in cross-section, of the upper part of a scrubbing tower and showing the application of the device of this invention;

Fig. 2 is a view of the preferred form of sp'attering means;

ig. 3 isa cross sectional view on line lll-III of Fig. 2, I Figs, 4, 5, 6, 7 and 8 illustrate various modifications of the spattering-means and attaching means, Fig. 7 being across-sectional view on line VII-VII of Fig. 6.

The spraying device in general comprises a nozzle '1 I through which liquid is forced, and'a spattering means 2 adapted to be placed ii -theupath of the jet of liquid coming from the nozzle. The spattering means 2 is .supported directly in front of the nozzle 1 by a stirrup '3. The stirrup is so constructedthat the position of the s atterin means2ina beadjustedwith respect to the nozzle. The

endso l and of the stirrup 3 are threaded toreceive nuts 6, 7 ,8 and 9.,byjmeansof which the stirrup is rigidly clamped in place on flange at the end of the nozzle 1.

Fig. 1 shows the use of the device in connection with a scrubbing tower 11 having an outlet 12. Any desired form of nozzle is directed into the top of the tower so as to project the liquid to be treated downwardly therein as, for example, through pipe 13.

The horizontal axial distance through the spattering means is preferably slightlygreater than the diameter of the st of liquid, for example, with a one and onereighth inch nozzle a ball of approximately two inches in diameter and supported about four inches from the nozzle gives the desired result.

With this arran ement li uid rates of from 1000- gallons per hour to 4000 gallons per hour give satisfactory distribution;

The spattering means is preferably of spherical. form and comprises a ball of corrosion-resisting material with a hole passing through the center thereof through which is passed a rod of relatively small diameter, such. as rod 3., of similar material. The ball is welded to the rod and held in the middle thereof. The rod is bent on either side of the ball and the ends passed throughthe holes in. the'fiange 10. The rod may be bent in,

the ball, it may be flattenedfora short distance on either side, as shown in Figs. 2 and 53, or it may be shaped as shown in Figs. 6

and 7. This, however, provides only a slight improvement over the use of a round rod.

The spattering means shown in Fig. 4 is .so shaped that the upper halfof a cross-sectional view through the vertical axis is sub stantially similar to a Gothic archand likewise the lower half in whichlatter case, the arch would be inverted.

In Fig. 5,.a sputtering means is shown with a flattened portion or belt 14, the upper and lower portions of the Said means being portions-of a sphere.

The spattering means shown in Figs 6 and 7 is so shaped thatthe upper. and the lower halves are substantially bullet-shaped with the free ends pointing in opposite directions.

When the device is in use, the liquid impinges on the upper substantially sperical surface and is so deflected that a relatively small amount of the said liquid reaches the sides of the tower and the entire area directly below the spattering means and the immediate vicinity is uniformly sprayed with the liquid,thereby insuring proper distribution.

I claim as my invention: In apparatus for treating gases with finely divided liquid, in combination, a shell, a

, liquid supply pipe passing through the upper portion of the saidshe-ll, the said pipe terminating in a downwardly directed nozzlew ithin the said shell and adapted to prothe said shell directly beneath the said bafile.

Intestimony whereof, I have hereunto subscribed my name this 23rd day of March,
