STEAM AND OIL SEPABATOR.

Specification of Letters Patent. Patented Nov. 30 1920 Application filed April 21, 1920. Serial No. 375,885.

ticularly adapted to remove oil or otherliquids from steam and has for its object the provision ofa simple and effective device in which the passing steam is deflected in various directions prior to its exit from the device, thereby causing the oil or other liquid therein to be separated from the steam and collected in a receptacle provided for this purpose.

The invention consists primarily in a collecting receptacle combined with an inlet chamber and an outlet compartment both communicating with said receptacle and in which the inlet compartment is provided with means for deflecting the incoming steam outwardly in helical paths prior to its admission to the outlet compartment which contains means for converging the steam inwardly prior to its exit from said casing.

The invention further consists in certain novel features of construction and arrangement of parts which will be understood readily by the description of the drawings and to the claims to be hereinafter given.

For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results although it is to be understood that the various instrumentalities of which the invention consists can be variously arran ed and organized and the invention is not 11mited to the precise arrangement and organization of these instrumentalities as herein shown and described, except as required by the scope of the appended claims. 4

Of the drawings:

Figure 1 represents a vertical longitudinal section of a device embodying the principles of the present invention.

Fig. 2 represents a transverse vertical sec tion of the same on line 2, 2 on Fig. 1.

Fig. 3 represents a transverse vertical section of the same on line 3, 3 on Fig. 1, and

.Fig. 4 represents a transverse vertical section of the same on line 4, 4 on Fig. l.

Similar characters indicate like parts throughout the several figures of the drawin s.

n the drawings, 10 is a casing having a chamber 11 and a compartment 12 alined therewith, said casing also having'a recepta'cle 13 beneath said compartment 12.

Between the chamber 11 and the compartment 12 is a partition 14: having a plurality of passages 15 extending therethrough' and forming a means of communication between said chamber 11 and compartment 12.

The .wall 14 is provided with an annular flange 16 extending into the inner enlarged end of the chamber-11, the end of said flange 16 being provided with a bead 17 on the periphery t ereof. l

The partition or wall 14 is also provided with a flat-sided depression 18in which is positioned a flat-sided projection 19 formed upon the inner end of a cylindrical member 20 having a plurality of helical blades 21 extending therefrom, the outer edges of said blades contacting with the inner wall of the chamber 11 near the outer end thereof.

The casing 10 has an. annular flange 22 agalnst the outer face of which is secured, by bolts 23, the member 24 having a spider 25 therein as indicated in Fig. 1 of the drawin The spider 25- has mounted therein a threaded member 26 having a reduced end 27 positioned in a depression in the outer end of the member 20.

This member 26 is adapted to be adjusted to retain the member 20 111 position and the squared projection thereof positioned in the flat-sided depression 18 prevents the member 20 from rotating about its axis.

To the opposite end of the casing 10 and in axial alinement with the chamber 11 and member 24 is secured a member 28 having a tubular depression 29 extending into the compartment 12 with its inner end positioned in acup-shaped projectionBO formed upon the wall 14 between the passages15.

The member 28yhas an outlet passa e31 therethrough and in the periphery 0 said tubular projection 29 is a curved flange 32 between the outer end of the cup-shaped member 30 and the wall 33 of the casing 10.

ceptacle 13 is a partition 34-curved downwardly at 35 thus leaving a passage 36 adjacent the wall, 33, said passage 36 providing a means whereby any liquid in the compartment 12 will flow downwardly through said passage 36 into the receptacle 13.

The receptacle 13 is provided with the usual gage 37 to indicate the amount of li uid Hi the receptacle 13.

he liquid collected in the receptacle 13 may be drawn oil as desired through the discharge pipe 38.

The enlarged inner end of the chamber ill is connected to the receptacle 13 by means of passages 39.

The helical blades 21 are provided on one side thereof with curved surfaces 40.

In operation the steam enters the device through the inlet passage 41 and having passed through the openings in the spider 25 strikes against the cone-shaped end 42 at the outer end of the member 20 thus forcing the steam outwardly into the helical grooves formed by the blades 21.

As a result of this construction the steam is subdivided as it passes through the chamber 11 and contacting. with the surfaces 40 is forced outwardly against the walls of said chamber 11.

This action causes a portion of the oil or liquid in the steam to be separated therefrom and pass downwardly into the bottom of the enlar ed end of the chamber 11 and then throug the passages 39 into the collecting receptacle 13.

Any liquid separated from the steam in the chamber 11 and dropping from the walls of said chamber onto the periphery of the tubular flange 16 will be retained on said flange by the bead 17 and pass downwardly through the passages 39 into the said collecting receptacle 13.

The steam passing through the outlet passages 15 from the chamber 11 into the compartment 12 will be at first forced outwardly by the curved outer surface of the cup-shaped member 30 and then will be converged within said cup-shaped member prior to its passage from the compartment 12 through the outlet passage 31.

Any liquid separated from the steam and collecting on the walls of said compartment 12 will pass downwardly onto the upper surface of the partition 34 and pass therefrom through the passage 36 into said collecting receptacle 13.

In like manner any liquid separated from the steam which may be on the periphery of the tubular projection 39 will pass downwardly therefrom through the passage 36 into the collecting receptacle 13.

It will be seen therefore that as the steam passes from the inlet 41 to the outlet 31 through the chamber 11 and compartment 12, said steam will first be forced outwardly in helical paths against the walls of the chamber 11 and then into the compartment 12 where it will be converged prior to its exit from the casing 10.

By this means any oil in the steam will be thoroughly separated therefrom and collected in the receptacle 13 provided for this purpose.

In like manner steam having other liquid contained therein will have said liquid eliminated therefrom and collected in the receptacle 13 thereby providing a means whereb when it passes through the outlet 31 it Wlll be free from moisture.

The present device is simple in construction, easily assembled and cheaply made.

It is believed that the operation of the device and its many advantages will be thoroughly understood without further descri tion.
