Application July 9, 1943, Serial No. 493,962 5 Claims. (01. 183-21) 1 2 the axis, as shown at 29 in Fig. 3, in the direction This invention relates to a device for washing - in which the rotating column of air passes and conditioning air and gases. It is the object through them, so that by their inclination they of this invention to produce an apparatus by tend to maintain the whirling motion of the air which a current of air may be continuously sub column and at the same time distribute the air jected to contact with a moving spray of water, around the periphery of the casing as it proceeds which will give a thorough co-mingling of the upwardly. The most favorable angle we have air and water and then provide a thorough sepa found is about 30° at the bottom, sloping to about ration of the air and water after treatment, with 15° at the top. a maximum simplicity of construction. It is a The hub I8 is provided with a lower conical end further object to produce an apparatus which 10 2|. will maintain the current of air in a circular or The vanes I5 preferably have their upper edges whirling motion while it is being passed through slanting downwardly toward the hub I8 and the spray of water so that it may mingle thor there is attached to the upper end of the hub l8, oughly with the spray and at the same time pro forming substantially an expanding portion of it, 15 ject any particles which may become entrained an inverted conical de?ector 22, upon which is in the air stream outwardly against the interior mounted an upright» conical de?ector 23, the edge of the apparatus. 24 of which extends over the edge of the de?ector The invention accordingly comprises an article 22 so that the air, passing with a whirling motion of manufacture possessing the features, proper upwardly between the vanes I9, is thrown 20 ties and the relation of elements which will be ex smoothly outwardly toward the walls of the casing empli?ed in the article hereinafter described and H] but Without directly impinging thereon.

These parts are similar to the coni Fig. 5 is a vertical section showing a modi?ed cal end 2! and de?ector 22 and 23 already de form of de?ector. scribed. A series of outlets 3|a are provided in In the drawing the numeral I0 designates a the edge of de?ector 3! to permit water to run cylindrical casing having a vertical axis and hav through ba?les 3! into the chamber 21. ing an air inlet II at the lower end attached to The de?ectors 36 and 3'! lie in a separating the casing tangentially (as shown in Fig. 4) so chamber 38, the upper end of which is de?ned by that the entering air is caused to move in a spiral an outlet coupling 39 having a downwardly ex path through the casing.

As it passes upwardly between the pending flange l1. Centrally spaced within this vanes i9, it passes through a sheet of water drip ?ange is a hub l8 supported from the ?ange by ping from the edge 24. Part of this water is im a series of radial vanes l9 which are inclined mediately thrown outwardly against the interior to the vertical and are attached to the ?ange l‘! of the casing IE! or against the ba?le l6 and runs at their outer ends and to the hub H3 at their 60 down between the vanes [9 to be thrown out inner ends. These vanes are set at an angle to 2,409,088 3 wardly by the centrifugal force against the cy lindrical wall, and some of it is carried upwardly by the air current. The air, however, passes smoothly past the edge 24 of de?ector 23—-24, passing inwardly toward the axis of the device . and thus through the path of the water dripping . from the edge 26 of the ba?ie 25, and passes up— wardly through the center to pass this edge 26 moving against the current of water falling from the jets and again being thrown outwardly bythe centrifugal force. Within the chamber 21 the combination of the rotating motion of the air column and the action of the jets causes a very thorough mingling of the air and the water without substantial eddy currents. The particles of water are thrown out wardly against the interior walls of the casing or upon the baiile 25, thus furnishing the sup-ply of water for the sheet which falls from the edge 26. The vanes 36 and the conical de?ectors 36 and El’ serve to eliminate from the air any drops which have been entrained therein, causing these drops to be caught by the vanes 34 or to be thrown » 4 ing the said channel into a plurality of upwardly extending passageways, said vanes being inclined to the vertical to receive the rotating column of air from said inlet chamber and maintain it in ‘ rotation and deliver it smoothly into the spray chamber. 2. ‘In an air washer, in combination, a cylin drical casing having a vertical axis forming a spray chamber and a separating chamber above said spray chamber, means to establish a rotary upwardly moving column of air within said spray chamber, jets within said spray chamber for pro jeoting‘ spray through said air column, an an nular ba?ie extending inwardly from said casing between said chambers and having a central opening, an inverted conical de?ector within and extending down into said opening, and forming with said ba?le an upwardly and outwardly ex tending annular channel, vanes attached along their inner edges to said conical de?ector and ex tending from said point of attachment radially outward and attached along their outer ends to the edges of said opening dividing the said chan nel into a plurality of upwardly extending pas sageways, said vanes being inclined to the vertical to receive the rotating column of air from said the air, as it passes outwardly through the cou spray chamber and maintain it in rotation and pling 39, is substantially free from any entrained deliver it smoothly into the separating chamber. moisture. 3. A device according to claim 2 in which said In the construction, as shown in Fig. 5, the 30 annular baiiie is provided with a drain opening to outwardly to the interior walls of the chamber 38, to be discharged through openings 3%. Thus conical de?ector 23 or 31 is pivoted as at 45 to a bracket 48 extending upwardly from the hubs I8 or 33, and the other edge may be supported by a suitable support 4'5. The chambers 21 and 38 are each provided with an access door ‘if! or 5!] through which the interior parts may be reached, and when the piv oted deflector shown in Fig. 5 is used, the de ?ector may be thrown upwardly to provide access drain into said spray chamber, water flowing down the inside of said separating chamber. 4. An air cleansing device comprising in com bination a cylindrical casing having a vertical axis, comprising an intake chamber at the bot tom; a spray chamber above said intake chamber and a separating chamber above said spray cham ber, said intake chamber having a tangential in let to establish a rotary motion in incoming air to the vanes l9 or 34 to permit proper cleansing of 40 to form a rotating column within said intake the same.
