ATOHIZEB.

Application filed August 3, 1926, Serial No.

For all reactions between gases and liquids a large contact surface between the gas and the liquid is necessary. Such large surface is frequently produced by atomization.

. The present invention refers to an atomizer which, without any essential consumption of power, will atomize liquids, emulsions, dispersions, solutions and the like, and this so finely that the surface becomes enormously great so that the physical or chemical reactions or both aimed at, such as the generation of steam, evaporation, moistening of air, condensation, drying,emulsification and the like will proceed with great rapidity.

The invention is based on the fact that a liquid wills read on a rapidly revolving surface and suc liquid will leave in the form of a film or several films which thereuponfwill be diffused by the air surrounding the revolving surface, while this air is either stationary or travelling'at a velocity which is different from that of the said surface.

In theaccompanying drawing a constructional form of an atomizer according to the present invention is shown by way of exig. 1 is a vertical longitudinal section through an atomizer.

Fig. 2 is a horizontal section through the atomizer.

Fig. 3 is a vertical longitudinal section showing a vane in detail and the spreading of the material over the same.

Fig. 4 is a top view of a section of the surface of the vane. with arrows indicating the fanlike spreading of the material.

Figs. 5, 6, 7, 8 and 9 represent sectional views of various forms of vanes taken on the line AB of Fig. 1.

An at om zer may, for example, be constructed in the following manner, see Fig. 1. On the top of-a rapidly revolving disc 7) which is suspended on the thin shaft 1 ided, in the bearing 3-are fittedeither per orated' .45 vanes 6 of. wire netting (Fig. 8) or'im'per ,forate vanes 6 which may take the form. shown .Rogesgfitlforth. wherein thevanes are perforated, substan- I tially as and for thepurposes set forth.

in Figs. 5, 6, 7 or 9. The upper edges of these i are covered witha plate 5 and astationary plate 8 which prevents the revolvingvanes siderably increase the consumption of power. The liquid is supplied to the vanes through "upper surface cut away to leave an annular arranged-radially thereo tion with each other, an annular plate con- 12e,a1s, and in Denmark October 13, 1925.

the pipe and the distributing case -'l.

The tubular support 9 is arranged about the shaft 1 and pipe 2 and carries and supports the stationary plate 8 in addition to serving to protectthe shaft 1 and pipe 2.

In .connection with the plate 8 it should be observed that the same prevents a current of air from being sucked into the chamber below the nozzles leading from the distributing case 4 and thereby prevents powdered material emanatin from the vanes 6 from clogging between he tube 9' and the plate 5 as it would be ,when entrained by the said current of air.

A speciallycharacteristic feature of the atomizer is the shape of the vanes which can be made convex, plane or concave towards the one side which is overspread with the luguld (Figs. 3 and 4.) that is to say' the front si e of the vanes with reference to their direction of rotation, as it is intended that the liquid should spread out thinlyover the whole vane while it travels along over it.

In Fig. 3 a certain way of the spreading over a vane is shown, and in Fig. 4 is shown the fanlike form in which the material will leave the vanes.

Having now described my invention, what so I claim as new and desire to secure by Letters Patent is-:,

1. atomizer consisting of a rapidly revolving disc having the outer portion of the all supporting surface, a plurality of vanes carried on the annular supporting surface and and'in spaced relanected with the upper edges ofthe vanes, a stationary disc arranged in spaced relation fto the revolving disc and in close relation to the plate on the vanes for preventing the air surrounding the vanes from being drawn along by the revolution thereof, 'and means mounted in the stationary disc for su plying material to atom i'zed tojthe space )etwccn e' di scs, substantially as and for the pur- ..An }atomizer"as claimed in claim 1,
