To all ywhom it may concern.'

Be it known that I, OTTO C. Buss, a citizen of the Republic of Switzerland, and a resident of Havre, France, have made a new and useful Invention in Jet-Condensers, of which the following is a specification.

This invention relates to condensers and more particularly to condensers of the ejecltor type.

In British Patent 8452 of 1905, Maurice Le Blanc discloses a novel fluid translating device applied to an ejector condenser, and an object of this invention is to produce an improved ejector condenser utilizing said Le Blanc translating device. This as well as other objects which Will readily appear to those skilled inthis art I attain by means of the device described in the specification and illustrated in the drawings accompanying the same and forming a part hereof, and throughout which Similar elements are denoted by like characters.

Figure 1 is a view in sectional elevation of a device embodying this invention taken on line 1 1 of Fig. 3; Fig. 2 is a view in elevation with a portion thereof taken in section on the line 2-2 of Fig. 1; Fig. 3 is a view of the device partially in plan and partially in section on the line 3-3 of Fig. 1; Fig. 4 is a top plan view of the device shown in Fig. 1; Fig. 5 is a view in sectional elevation of a modification of this invention; Fig. 6 is a view in elevation with a portion thereof shown in section and taken on line 6--6 of Figm; Fig. 7 is a view partially in plan and partially in section on the line 7 7 of Fig. 5 looking down upon the device shown in Figs. 5 and G.

In carrying out this invention I employ the fluid translating device invented by Maurice Le Blanc and disclosed in said British patent. This consists of a rotatable irnpeller provided with an annular row of blades and a water or other liquid distributer having a delivery nozzle for delivering or distributing water to a number of the blades of the impeller in such a way that, at any given instant water is delivered to less than the total number of blades, thereby making the impeller a partial injection or partial influx impeller, or it may be described as a partial ejection or partial ellux impeller. As shown in Figs. 1 to 5,y water is delivered to not more than three of the blades of the impeller at any given instant. The water delivered by the distributer to the impeller is minutely subdivided on account of the high rotational speed given to the impeller by outside means, such as a motor or steam turbine, and projected therefrom in the form of films or leaves of relatively high velocity.

I have found that when Le Blancs fluid translating device is utilized in a condenser such as disclosed in said British patent while it is highly efficient as a condenser it is not capable of taking care of the noncondensable vapors which enter`the condenser. In the condenser of the said British patent the leaves or lms of liquid projected by the impeller are projected or discharged into a relatively large chamber and therein are allowed to spread out so as to present a greatly extended surface for condensing purposes. Condensers of this type are largely used in connection with steam turbines as well as in connection with reciprocating steam engines and while turbines are not as liable to have air leaks as reciprocating engines the piping between the turbine and the condenser is always more or less a source of trouble in this regard.

The device illustrated in Figs. 1 to 4 consists of a body portion 8 having formed in one side thereof a chamber for the rotatable impeller 9. The chamber is provided with end plates 10 and 11 through which the shaft 12 of the impeller 9 passes. End plate 10 is provided with a stuling box 13 for the shaft, and end plate 11 is extended so as to form a water chamber 14 having a flanged opening 15 and is also provided with a stuling box 16 for said shaft.

Between the body porti'on 8 and end plate 11 a flange of a water distributer 17 is adjustably secured and said distributer is formed so that it projects withnlthe ring of impeller blades 18 which are arranged in an annular row projecting from one side of the impeller disk. The distributer is provided with an outlet nozzle 19 which by means of turning the distributer 17 may be adjusted to the proper position desired in order that water may be fed or distributed to the blades of the `impeller at just the proper point.

Bearings 20 and 21 are provided for the impeller shaft 12 and while bearing 20 is carried on a bracket 22 secured to end plate 10, bearing 21 is carried on the extension of end plate 11. Impeller shaft 12, it will be understood, is adapted to be rotated at the desired speed by any suitable means such as a reciprocating engine, an electric motor or a steam turbine and the shape and angularity of the blades, as well as the position of the nozzle 19, will be determined'by the peripheral speed given to the impeller by the motor which drives it. .i

Body portion 8 is provided with a top or capmember 23 which has an inlet 24 arranged in the side thereof and an inlet covered by cap 25 arranged in the top. This is done in order that the condenser may be connected in either way desired;

Body portion 8 4is secured to a bed plate 26 which has downwardly projecting walls 27. Below the body portion 8 and bed plate 26 and within the walls 27 a converging tube or collecting and combining tube 28 is 1ocated, and to the lower end of the walls 27 a divergent transformer or diffuser 29 is secured. Between the outlet end 30 of the collecting tube 28 and the inlet to the diffuser 29, a steam cone 31, for the purpose of priming the condenser, is located and this cone which lis formed so as to leave an annular' passage 32 between it and the diffuser shell is adapted to be supplied with steam through an inlet 33.

All this portion Qf the device thus far described, it will be found, is substantially the same as th'edevice shown in the Le Blanc British patent before referred to and I have improved said device bv adding thereto a 4device such, for example, as a collecting f thev apparatus refer to the cone 34 as a stabilitator for the reason that it insures a more uniform, operation of the apparatus and causes the condenser to hold a more stable or uniform vacuum.

Operation: Assuming that either the inlet 24 or the inlet shown closed by the cover plate 25 is connected to a source of fluid or steam to be condensed; that the water inlet 15 is connected to a suitable source of water supply; that the steam inlet 33 is connected by means of a valved connection to a suit-g able source of steam supply; and that the impeller 9 is rotated at'the desired speed in a direction such that its blades 18 move downwardly past the discharge end of the nozzle 19. Under such conditions, priming, by admitting steam to the port 33, will fill the dis'- tributer chamber with water. If the water is delivered under pressure to the distributer chamber, the priming will not be necessary. This will cause water to rise and fill the distributing chamber and flow out through distributer nozzle 19. The, blades carried by the impeller moving past the distributing nozzle 19 will cut off the water, so to speak, andproject it in the form of films into and across stabilitator 34 and these films of water will move at high velocity through the stabilitator, and on account of its convergence, will be compressed into amore or less' compact stream which will issue vfrom the outlet thereof and move toward and through the collecting tube 28 in the form of a stream having a high velocity. The stream on issuing from the outlet 30 of collecting tube 28 passes into and through the diffuser`- 29 and therein the Huid velocity is transformed into pressure in the well-known manner, on account of the divergence of the walls of the diffuser. The steam within the body 8 will be condensed in a two-fold manner; that is, a portion of it will be condensed by means of the films of Water projected into the stabilitator and a portion thereof will be condensed by contacting with the stream issuing from .the outlet of the stabilitator and traversing the collecting tube 28. The non condensable vapors within the body portion 8 will be confined between the leaves or films of water and will be carried by them through the stabilitator and into and through the tube 28 and will be discharged therefrom into the diffuser in which the -velocity thereof will be transformed into pressure. A portion of the non-condensable vapors, of course, will be carried through the tube 28 and into the diffuser by means of the friction between the stream made up of the leaves of 'Water and the non-condensable vapors. As the tension of the fluid in the immediate vicinity of the inlet of the stabilitator will be less than the rtension of the fiuids in the other portions of the body8, the non-condensable vapors as well as the condensable vapors, will have a. tendency to i How into the stabilitator, and, will b f means of the leaves of water, be carried therethrough and compacted by the walls of the stabilitator into a more or less solid stream.

While the condenserI shown in Figs. 1 to 4 are arranged axially in line and adapted to operate in series. The leaves of water pro jected by the impeller are projected into and across stabilitator 36, and, after being compacted therein into a more or less solid stream, pass through stabilitator 37 and then through a combining tube 39, of slightly different form than combining tube 28. By means of these two stabilitators 3G and 37, the stream issuing from the upper stabilitator 36 is kept in contact with the fluids within body portion 8 for a longer time and in this manner I am enabled to handle more non-condensable vapors thann by the use of a single stabilitator.

In accordance with the provisions of the patent statutes, I have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the apparatus shown is only illustrative and that the invention can be carried out by other means.
