't Application sied July 10,1915. serialNoQaaoca f i To cham 1f/Inail( concjra Be it knownthat I, RAYMOND CARPENTER,

'f a citizen of ytheUnitedStates, residing at East Orange, .county of Essex, and State of New- Jersey,'..have invented certain new and useful Improvements in Steam-Sepatrators.; and Indo hereby declare'the follow.- ing to be a full, clear, and eXact description of thel inventiorn, such as will enable others skilled in the art `to ,Which it appertains to make and `,use `the same.

This invention relates to steam sepa'- \`rator.s f orI usein extracting particles of upon jwhich the liquidv particles impinge so as to become @separated from the steam. Also, ith'as been commonto cause the steam toassume a circular .lofw inorder that the liquid particles-wil-lbe thrown off by centrifugal force: 'i- The separator constructed accordance-.with the present invention differs from theseprior types primarily in that `it is so constructed as to cause the steam to be. divided fs-into two or more streams which are subsequently caused vto vflow into each other. As aI result of this, the particles.offliquidfinzthe steam drop to the bottom yof the separator and then pass o through 4a suitable drip connection. Preferably,xavaneor blade is employed yin the path ofthe incomingsteam adapted to d1- vide: the steam into,l two streams and curved Walls guide-thesektwo. streams in circular paths so as to cause them to flow into each other. ,while the-Steam is sowing in this manner,l more lfor: less .of the liquid particles contained..'thereinfxare` extracted due vto the impingement of liquid particles upon the fvaneandl also `Ktosthecentrifugal force exertf edvupon the liquidy 'particles while they are flowing the'curved path. Then, when the twoAv streams` meet, they arrest each -other momentarily'as` a result of which particles ofmoisture remaining in them may drop b lgravity and4 liquid-deposited 'upon the Walll of the separator may 'HOW downwardly to the water outlet insteadof carried along by the stream.

Provision fortheflow of steam through the separator in the mannervabove indicated is preferably made'by` providing an .inlet passage for the steam extcndingwithin a casing of substantially cylindrical. l formand located eccentrically with respect to the casing. rThis inlet passage has an opening on o ne side thereof and opposite this openingis a yvane or blade employed for dividing the incoming steam into two streams. .Ihe

opening in the inlet vpassage is locatedgon the side of the passage which is nearestwto the side of the casing, so that the-two paths for the steam flowing from the vane-around the casing to -the outlet are paths ofy con- Specification of Lett'erswPatentf S' 'i '7; 5

stantly increasing area ,As agresult offthis,

the velocity of the steam, in its llow'from lthe vane around to the outlet is greatly defcreased and the separation of" liquid particles from the steam .therefore takes pla-ce more e'ectively. Furt-hermore,the outlet as; 'i

sage for the steam .eXtendsinto the "casing of the'separator. a substantial distanceto more'Y effectively guard against the passage l*of particles of liquid intothe outlet opening, particularly particles which havebeen i thrown yout upon :the wall of .thecasing The preferred1 embodiment of the invention is illustrated in the accompanying drawings, in which Figurer l is a top-view of apparatus embodying my improved form of separator, the separator being shown in horizontal section online 1-1' of Fig. 2, and Fig. 2 is a view partly in central,,vertical section of the apparatus shown-in Fig. l;

Inv the drawings,.I haveillustrated my irnsog proved form of separator as applied to an evaporator of the type adaptedy for use in evaporating salt-water .to obtain Water which is free from salt. The evaporator shown consists of a casing 3 of substantially cylindr-ical form adapted to have saltwater adt mitted thereto. Withinthe casing are `la plurality of coils of pipe Llthrough which steam is caused to How to vaporizel the Water within the casing. The steamris'inghfrom the Water Within the casing passes'arfound ya baffle 5 and into the separator which' is located on top of the casing 3.'

The separator shown is-infthe'forni .Kofa e t; dome mounted on top of the evaporator and consists of a cylindrical casing 6 closed at its.

upper end '7.' The lower end'of the casing 6 is provided with` a flange 8 to facilitate attachment `of the separator to the casing of t wardly, as shown at `1() in Fig. 1. Directly opposite this opening inthe side of the in- `let'passage is a vane or blade 11, V-shaped in horizontal cross section and having the apex of the V located opposite the center of the opening` in the wall of the inlet passage 9. The walls of this V-shapedblade merge into the side walls of the casing 6, the construction being such that l'steam flowing through the opening in the inlet passage 9 is divided by the vane 11 into two streams which aredelected laterally and caused to flow in semi-circularpaths around the side walls of the casing 6.

The outlet for the steam,` from the separator is locatedvupon the side of the inlet passage 9 opposite that in which the opening abovedescribed is provided. This `.outlet consists of a tubular member 12 progecting inwardly from the wall ofv the casing 6 and a pipe 13 forming a continuation of the tubularmeinben Itwill be noted that the tubular member 12 pro]ects inwardly from the wall of the casing 6 a. substantial -distance so that water whic, has impinged upon the sidewall of the separator cannot be carried into the outlet opening.

The separated water and other liquid passes downwardly within the separator and 1s deposited upon: the inclined bottom wall y 14 thereof over which it flows to the drip opening 15. This drpopening is extended downwardly by a pipe 16 to a point below the levelI of the liquid within the casing 3 of the evaporator. i f

Inoperation, the steam rising from the water within thecasing 3 passes around the baflle 5 and 'into the tubular'inlet passage 9. From this passage ythe steam passes through the opening and is divided by the vane 11 into two streams which flow in opposite directions around the side walls of the casing.

` 6. As the stream passes but of the inlet o ening and into the separator proper, many o? the particles of liquid carried by the u `steam impinge upon 'the walls of the vane 11 and the adjacent sideV walls` of the separator and these particles Apass downwardly by avity to t theA bottom of the separator.

' 9: aS the steam is flowing around its semi-I circular courses from the vane 11 to the outlet12, the particles of liquid contained therein are subjected to 'centrifugal force which tends to throw them "outwardly and deposit them upon the side walls of the separator upon which they flow downwardly by gravity. It will be noted that by reason of the eccentric location of the inlet conduit 1l with respect to the cylindrical casoutlet opening 12, the two streams of steam l flow into each other and mutually arrest each other so that particles of liquid remaining in the steam are allowed to drop by gravityto the bottom of the separator. The steam itself, then freed from the water contained therein, passes out through the outlet consisting of the tubular member 12 and the piping 13 leading from that member. Since the outlet member 1:2 is extended into the casing 6 of the separator, water which has collected upon the wall of the separator will not be carried by the steam into the outlet opening where it would be again taken up' by the steam. The water separated from the steam collects in the bottom of the separator and passes out through the pipe 16 to the body of water within the evaporator 3.,

It willbenotedby reference to Fig. 2 that the lower end of the inlet opening 9 extends below the bottom wall 141' of the separator.` This extension of the inlet opening serves as'a'baiie to prevent splashing and surging ofthe water within theevaporator and' is of special utility for this purose in apparatus for use on ship board. uch a downward extension of the inlet 9 'below the bottom wall 14 makes it permissible toomit the battle 5 below the separator in' some instances, particularly when the evaporator is of relatively small size so that splashing and surging of the water therein takes place to a less extent. These and other modifications of the construction herein .illustrated and described, I consider within the scope of my invention and I aim to cover a `such modifications by the terms employed in the claims appended hereto.

What I claim is :I`

1. A steam separator comprising a drum 'or analogous vessel having eccentrically supported within it a steaminlet with an 'opening facing the near wall of the drum, means for directing the steam passing from the'i steam `inlet through the opening against. the drum wall in ltwo substantially unob-i' structed streams `of enlarging area and decreasing velocity around the circumfei`v ential face of said wall until they arr arA iso rested by meeting one another, and an outlet passage for the dry steam.

2. A steam separator comprising a drum or analogous vessel having eccentrically supported within it a steam inlet with an opening facing the near wall of the drum, means for directing the steam passing from the steam inlet through the opening against the drum wall in two substantially unobstructed streams of enlarging area and decreasin velocity around the circumferential face 0 said wall until they are arrested by meeting one another, and an outlet passage for the dry steam located at a point opposite the point at which the steam is discharged against the Wall.

8. A steam separator comprising a drum or analogous vessel having a substantiallyY continuous circumferential wall7 means for directing the fluids to be separated against the face of said wall, a projection on said wall substantially opposite the middle of the inlet opening for separating the fluids to be separated into two streams and directing such streams in opposite directions around the Aface of said circumferential wall, and an outlet passage for the steam having its opening at a point within and removed from said circumferential wall.

4. A steam separator comprising a drum or analogous vessel having a substantially continuous circumferential wall, means for directing the fluids to be separated against the face of said wall, a projection on said wall substantially opposite the middle of the inlet opening for separating the fluids to "be 'separated into two streams and directing such streams in opposite directions around the face of said circumferential wall, and an outlet pipe for the steam projecting through the wall of the drum opposite the point at which the fluids to be separated are discharged against the wall with the opening into the pipe away from the wall of the drum.

5.v A steam separator consisting of a drum of substantially circular cross section, an inlet passage for the fluids to be separated projecting longitudinally 4into said drum', said inlet passage opening radially adjacent one side wall of said drum, a projection on said side wall opposite said opening for directing the fluids to be separated in two streams in opposite directions around the inner wall of said drum whereby said streams will come together at the opposite side of said drum, and a discharge pipe for the steam projecting through the wall of the drum opposite the said projection, the opening into the pipe being spaced away from the wall of the drum whereby the water in the two streams will adhere to the wall of said drum through its greater centrifugal force while the steam will be drawn away from the wall by the suction of the discharge pipe.

In testimony whereof I aiiiX my signature.
