COOLER'AND SEPARATOR.

Application filed December 26, 192.2. Serial No. 609,162.

To all whom t may concern:

' Be it known that I, WILLIAM L. R. EM-

4 MET, a citizen of the'United Statesgfresidingat Schenectady, in the county of Schenectady, State of New York, have invented certain new and useful Improvements vin Coolersand Separatore, of -which the fol-A lowing vis `a speciication. The present invention relates tov an aprparatus for cooling a mixture of c ondensible and non-condensible vapors and separating the condensate formed from the non-condensible vapors.

, An application of my invention is 1n connection with mercury turbine systems wherein in connection vwith the shaft packingsof the'turbinethere is some leakage of mercury vapor which it is desired to condense and save. This mercury vapor is taken from the packing in the form ofl a mixture of the vapors with air Vor other non-condensible gas, `there being ofcourse, some liquid particles of mercury, :and the object of my 1nvention 4is to provide a combined coolerand separator. which will-function to' cool the 'mixture so as to condense the vapors andseparate the condensate from the air orfj other gas.

-4 For a consideration of what'I believe to be noveland my invention, attention is directed to the vaccompanying' description and the claims appended thereto.

In the drawing, v4Fig. 1 1s a longitudinal Vsectional view `of a cooler and separator mbodying my invention, and Fig. 2 a perspectiveview' of certain parte..`

Referring to the drawing, 5 lndicates a lcylindrical casingprovided with a ilange' 6 atl its upper end to which is 'fasteneda head 7 by bo ts'8. Casing '5 is'made of relatively thin vmaterial and fiangeu which is much terminates short ,of thev top thicker sformcd advantageously by welding` 4a collar to the end of the casing. 'Suit- :ab y

fastened to head 7 and dependlngxfrom it 1s an inner cylinder 9 which termlnates Short-of the bottom of casing 5. Ihelower end of casing 5 is closed by a head 10 which may be-welded to the casin as indicated vat 1&1.- Supported on head 10 y suitable spacing blocks 12 is an intermediate cylinder 13 `w ich is closed at its lower end by ,a headli. The upper end of cylinder' 13 is open and There is thus formed in 'casing a/centra'l chamber 1 5 surrounded by two .concentric mediuminlet conduit 'conduit 37. 1 The apparatus may be of casing 5.

annular chambers 16 and 17. In ychamber -17 is a spiral deflecting strip 18 which extends from the lower end of the chamber to the upper end. In central 'chamber 15 are .a number of cone-shaped screens 19 preferably made lfrom cloth. Screens 19 are fastened between pairs of rings 20 at their larger ends and to a central' post 21 -at their apices.` Rings 20' are carried byrods 22 which at their upper ends are fastened to head 7 and at their lower ends to a spider 23. The rings are spaced by sleeves'24 on Projecting up through the, bottom of well -25 is a .discharge plpe 27;' the upper end of which terminates a suitable distance above such bottom.. `Over the'end of pipe 27 lis van inverted cup 28 which is fastened to the side ofthe pipe and depen-ds to a point well below its top. Atthe central ortion of llead 14 is an opening 29 to whlch is connected a depending sleeve .30 which extends well down linto well 25. This arrangement provides anannular passage lthrbugh.

which yannular chamber 17 is connected to well 25 and an annular passage 32 through vwhich' annular' chamber 16 and centralA chamber -1 5'are connected towell 25. lThe -inner'surface of head 10 is beveled to pro. '.vide a wall which Vslopes toward central opening 24". .At thelower lend of'casing 5 is. an admission conduit 33' and at the centery ofhead'? is a' discharge con-duit 34..

Surrounding casing 5. is a wall 35. which forms a cooling jacket having a cooling 36 and a discharge suitable manner. In the present instance it is shown as being fixed to .angle irons 38 carried by posts 89.

j In `operation, the vapor mixture, forexample; vair and mercury vapor, enters through conduit 3 3 and flows upwardly through annular chamber 17 beingdirected in a spiralcourse around casing 5 by deiecting strip 18. At the same time cooling medium Hows in through conduit 36 through supported in any the cooling jacket and out through conduit 37. Ordinarily, water is used as thecooling l medium. The vapor lmixture is cooled in passing up through annular chamber 17, the deflectingstrip ser-vingto bring it into engagement with the cooled outer wall of the chamber and this Vefi'ectsthe condensation of the condensible vapors in the mixture. The major. portion of the condensate will fall down on to head and flow through open-- ing 24a into well 25. Some liquid particles, however, will be carried along with the non-condensible vapors which .vapors after reaching the top of chamber 17 are directed down through annular chamber 16 and thence upwardly again through chamber 15 to discharge conduit 34. In owing from chamber 16 to chamber l5 a considerable portion of any liquid particles will be deposited on head 14 from which'the'y will run down through opening 29 and annular passage 32 to well 25.l Any particles carried on into chamber 15 will be caught by. screens and iind their way down to well 25. Everyparticle of condensate is thus removed from the vapors and directed to well,

Discharge pipe 27 projects above the bottom of well 25 a distance suiiicient to maintain a predetermined level of liquid in the Welland cup 28 and sleeve 30 dip down into such liquid so as to form a liquid seal at the bottoml of casing 5.

-My invention has particular utility as a separator for mercury since mercury is relatively expensive and it is important that every particle be saved. By theI use of my invention the incoming vapor mixture is thoroughly cooled and the mercury or other condensate-'efficiently separated out. YAt the Y same time the apparatus is simple in strucby Letters Patent of the United States, is
