Application filed November 23, 1905. Serial No. 288,701.

France, have invented a new and useful' Improvement in Condensers,.of which the following is a specification.

rI"his invention relates to condensers, and more particularly to the type known as jet condensers.

The object of this invention is to produce a simple apparatus of the class above inentioned which is extremely eiiicient and adapted to awide range of application.

A further object has been to produce a rotary jet condenser in which simple mechanical means are utilized for breaking up the flow of condensing liquid and causing it to be ejected from the condenser at a high velocity so -that it will -condense and carry away the vapor or gas to which it is exposed and. thereby create 'and maintain a desired vacuum. attain in a condenser embodying in its make up the elements herein described and illustrated' in the accompanying drawings, throughout the several views of which like parts are designated by corresponding characters. I

Figure 1 is a vertical section of a condenser embodying this invention. In Fig.

`2 the condenser is shown' partially in elevation and partially in'scctionlfor convenience of description. Fig. 3 is a diagrannnatic representation of a reversely rotated water embodyingl adetail of this inven` turbine tion. A

yThe essential features of this invention are a condensing chamber communicating with the exhaust uid passages of an engine or with other sources of vapor lto be'condensed, to which the condensing liquid is admitted through a rotating nozzle which is adapted to break up the flow of 1iiquid into a mass of separate drops; a reversely` rotated water turbine arranged to lreceive the condensingliquid issuing from the-condensing chamber and discharge it at a high velocity into the exterior passages of the condenser or into*` the atmospher'eand therebyV create and maintain a vacuuml within the condenser, as will be more fully described mhercinafter.

This and other objects I Fig. 8, the water leaving the a turbine wheel 6 through ag passa e 7 with an absolute velocity The turbine wheel 5 is rotated by some mechanical means in the direction of the feathered arrows so that the blades 5 have a'peripheral velocity V. The water entering the turbine is acted 0n by the blades and the absolute velocity tv of the water combines with the peripheral -velocity Vcf the blades to form a velocity "W relative to the blades. The relative velocity l/V is overcome by the centrifugal force occasioned by the rotation of the turbine and the water' is then projected radially by this centrifugal force and tends to leave the wheel with a velocity approximately equal to and of opposite sign from the velocity YV( This velocity combines with the peripheral velocity V of the blades and forms an absolute velocity c, superior to the' velocity 'w of the water at its entrance to the wheel. The blades 6, as in all analo gous cases, are so arranged that the water is received and discharged by them with as This angle varies of course for different ve.

locities of the turbine and of the entering water. f

Referring to Fig. 1: YThe vapor to be condensed enters a condensing chamber 9,

through an inlet opening 10. The walls of' the condensing chamber 9 gradually converge, forming a passa-ge or combiningtube 7. Condensing 1i uid` is introduced into the "chamber l9 throng a supply pipe-12 and is fili'acharged into a jrotary distributer 13 mounted on brackets 14 which are supported by walls 11. Thedistributer 13 consists 0f two or more branch pipes 15 connected to a 'main pipe 16 and is adapted toghe rotated by the water passing through it so that the'v issuing jets of water flow successively through all parts of the lower portion of the chamber-9. The combining tube 7 connects with-a collecting or pump chamber 19.

in which the reversely vrotated water' turbine 6 islocated. The portionireferre'dto as the reversely rotated turbine is in reality a pump impeller and will be so termed throughout the following description. The nnpeller 6 is mounted on the shaft 8 which is suitably journaled in thevframe portion 17 of the condenser and is provided with an operating pulley 18. The condensing liquid, discharged from the combining tube 7, is received by the blades of the impeller and dischargedfrom the chamber 19 through a converging nozzle 21. nects with a diffuser spout 23, to which is connected the exterior passage 24 of the con-I denser. The pump chamber 19 besides being connected to chamber 9 by the passage 7 is also connected to said chamber 9 by means introduced into the chamber 25 through the passage 26. The steam in vdischarging through` the passage '27 'and the diffuser spout 23 into the atmosphere acts as an ejector and the air or other non-condensable fluid contained within the condensing chamber is drawn through the passage 20 and opening 22 in the discharge, nozzle 21 and carried by means of the stream passing through the discharge nozzle through the diffuser andmuaygayufrom the apparatus. -By

v...fthistm'iisvthe air in lthe steam lentering the condenser, as well as the air liberated from the condensing water, 1s removed from the apparatus. By creating a partial vacuum in the condenser, the condensing liquid is caused to enter the chamber 9 through the supply pipe,12 with a velocity corresponding to the diHerence in the pressure between the condensing chamber and the atmosphere. After a desired entrance velocity vof the condensing liquid has been attained, the steam supplied to the chamber 25 is shut off, since the water in passing through and out of the condensing apparatus will maintain the vacuum. The condensing water issuing from the supply pipe 1'2'enters and rotates the distributer 13 from which it is discharged in a shower of' spray into the chamber 9. The shower of condensing water, in passing through and out of the condensing chamber, condenses and carries with it the vapor, air or other gas to which it visexposed. The converging walls of the combining tube7 collect the spray and form it; into al stream which is discharged onto the rotating blades of the impeller. The condensing water discharged from the impeller 6, because'of its high velocity, passes through the nozzle 21 andl the diffuser spout 23 intothe atmosphere or exterior passages pf the condenser. The water or condensing 'iqu'id in passing through the condensing apparatus, because of its condensing action and The nozzle 21 con-4 tained without increasing the diameter ofv the reversely rotated turbine.
