. w. E. GREENAWALT APPARATUS FOR TREATING LIQUIDS WITH GASES Filed June 9, 1922 Patented Feb. 17, 1925.
UNITED STATES PATENT OFFICE.
APPARATUS FOR TREATING LIQUIDS WITH'GASES.
Applicationiflled. June a,
To all whom it may concern:
Be it known that I, WILLIAM E. GREENA- WALT, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Apparatus for Treating Liquids with Gases, of which the following is a specification.
The invention has for its object the effective atomization, or fine subdivision, of gas in liquid, to accomplish certain results, as for example, the a plication of gas to liquids to facilitate esired chemical reactions, and in the flotation treatment of ores.
The invention may be considered as an improvement, or modification, of patents issued to William E. Greenawalt, No. 1,374,500; April 12. 1921'; No. 1,374,446, April 21, 1921: and No. 1,374,445, April 12, 1921.
In the operation of the apparatus as described in the above patents, it was found that excellent results can be obtained under some conditions and for some purposes by the use of a serrated periphery of the hollow rotary gas distributor with gas discharge passages arranged so that their outlets terminate in the peripheral serrations.
The invention can best be described by referring to the accompanying drawings,
in which, Fig. 1 shows a vertical section of the apparatus in which the air, or gas, is introduced into the hollow rotary member through a hollow shaft: Fig. 2, is a modification of Fig. 1, in which the air is introduced through a stationary pipe; Fig. 3 is a horizontal section of the rotary gas distributor, or atomizer:-Fig. 4: a detail vertical section of the atomizer as shown in Fig. 1: and Fig. 5 a detail vertical section of the atomizer as shown in Fig. 2.
Referring to Fig. 1 of the drawings, 1 is a tank adapted to contain the liquid to be treated, 2 is a rotary atomizer suspended within the tank by means of the hollow shaft 3 and submerged in the liquid. The atomizer has a hollow interior communicating with the hollow shaft, and is provided with dischar e passages 4 extending outwardly, prefera lv from the centrol portion toward the riphery. These discharge passages are ormed by the curved vanes, or partitions, 5, and are adapted to discharge the g or gas n q r m he n r r 1922. Serial No. 567,225.
of the atomizer toward its periphery and into the surrounding liquid in the tank.
When the atomizer is rotated at a proper speed, the air will be sucked down through the hollow shaft. This speed will usually range from 250 to 800 R. P. M., depending tion 9 of the modified atomizer 7, through a stationary pipe 10, so arranged that air will flow into the interior of the atomizer either by suction, or by pressure from the outside, and liquid from the tank will flow into the interior of the atomizer through the annulus 12 formed by the pipe 10 and the lower portion 9 of the atomizer.
In either arrangement as shown by Figs. 4 or 5 it has been found that better results are obtained under some conditions and for some purposes by terminating the exterior of the discharge passages 4 at approximately a right angle, as shown by 16, Fig. 3, than by the acute an le formed by the peripheral circle 14. is condition may be regarded as formed by recessing, or cutting away, a portion of the periphery as shown by 15, so that the periphery of the atomizer will have a serrated appearance, as shown in horizontal section in Fig. 3.
The ejecting of a mixture of gas and liquid from the interior of the atomizer into the surrounding liquid in the tank gives a finer atomization than when only gas is ejected. In Figure 5 this may conveniently be realized by introducing the air throu h the pipe 10 1n regulable amounts and t e liquid through the annulus 12. In Fig. 4 it may conveniently be realized by havingan opening 6 in the lower portion of the atomizer, so arranged that it may be closed with'a plug, so that'if desired only air will be ejected. r
I claim:
1. In apparatus for treating liquids with gases, a tank adapted to contain liquid, a hollow rotary member journaled on a vertical axis suspended within the tank and submerged in the liquid, said rotary memher having discharge passages arranged so that two adjacent ischarge passages have a common partition and so that the outlet of one discharge passage is recessed relative to the common partition, said common partition of one discharge passage being adapted to deflectliquid away from the outlet of the other discharge passage and a tubular member adapted to deliver gas to the interior of said rotary member.
2. In apparatus for treating liquids with gases, a tank adapted to contain liquid, a hollow rotary member journaled on a vertical axis suspended within the tank and submerged in the liquid, said rotary member having discharge passages with divergent partitions toward the outlets and with the outlets of the discharge passages arran ed so as to form a serrated periphery e rotary member, and atubular member adapted to deliver gas to the interior of said rotary member.
3. In apparatus for treating liquids with gases, a tank adapted to contain liquid, a hollow rotary member journaled .on a vertical axis suspended within the tank and submerged in the liquid, said rotary memher having a serrated periphery and discharge passages arranged with divergent sides extending outwardly and terminating in the serrations, and a tubular member adapted to deliver eras to the interior of said rotary member.
