To all whom it may concern:

* Be it known that 1, ROBERT SUCZEK, a citizen of the Czecho-Slovak Republic, residing in the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements 1n Apparatus for Compression and Condensation, of which the following is a speclfication.

My invention relates to apparatus for condensing fluid, as vsteam, and removmg uncondensable fluid, as air, which may be contained in or in association with the condensable fluid before or after its condensation.

My invention resides in condensing apparatus of any suitable type, more particularly a jet condenser, with which is associated air removing apparatuscomprising an ejector which discharges through a passage or passages within which the con- (lensable fluid from the mixture of the ejector is condensed and the uncondensed fluid cooled by extraction of heat from the walls of said passage or passages by cooling me dium, as water, which is preferably that which has theiretofore efi'ected condensation of steam in the condenser. With such ap- JaratuS may be associated a pump for urther raising the pressure of the uncondensed fluid from the ejector, said pump be ing of any suitable type and is preferably another ejector.

My invention resides in the method and apparatus hereinafter described.

For an illustration of one ofthe various forms my invention ma take, and for an illustration of a mode of practising my invention, reference is to be had to the accompanying drawing, which is a vertical sectional yiew, partly in elevation, through a jet condenser having associated therewith air'removing apparatus. V

Referring to the drawing, J- is the or shell of a condenser of any suitable type, here. illustrated byway of example as a jet condenser. I The fluid to be condensed, as steam-exhausted from a steam turbine, en-

gine or "any other source, is delivered-into the top of'ithe condenser through the opening-'A. -The cooling medium, as water, is

admitted through the opening W into the annular Water box or distributing chamber (1, from which it is delivered through the nozzles or openings N arranged in a cir- 'cular serles 1n the wall of the condenser shell or body. Beneath the nozzles or apertures N isthe cone or diffuser member D..

Within thebody or shell J, or otherwise suitably related therewith, is disposed a centrifugal removal pump P, whose impeller I remains submerged beneath the water collected in the bottom of the body J. The impeller I is secured upon and rotated by the 'shaft S extending through the shell J through'the stufiing boxes a, a and driven externally by any suitable means, as an electr1c motor orsteam turbine, not shown. The impeller I delivers into the pump discharge casing b, which communicates with the exterior of the condenser.

At a suitable point, as 0, above the variable level 03 of the water collected in the shell J, and preferably at a point above the lower end of the cone or diffuser D, a fluid connection with the interior of the shell J is provided and connecting with the valve 6 which delivers to the suction chamber of an ejector E of any Suitable type, here indicated as a downwardly directed tubular ejectorwhose difluser delivers into the pipe ,f. Motive fluid, as live or exhaust steam, is delivered to the nozzle structure of the ejector E through the pipe 9 controlled by the valve 'h. The pipe or fluid connection communicates at its lower end 'with the chamber a, separated b partition 7' from the second chamber is, c ambers i and k being separate compartments within the box or chest BL Connecting the chambers or compartments or k are the tubes Z, of any suitable material, preferably of good heat conductivity, such as cop er, brass, etc. These tubes in the example illustrated have their ends in the tube sheet or plate m which in eflect'forms part of the wall of the shell J, and extend j horizontally ining therebyjfsubmerged within the water collected in; :the condenser shell The tubes Z are preferably'located as Sir a distance below the ejector E as is consistent with their being '.a ways completely or suflil ci'ently submgrged in the water within the shell J-an'd, as indicated,"are accordingly rod preferably as low as the uppermost part of.

the pump impeller I, which is also always kept completely filled or submerged. The

chamber is communicates through a fluid connection, as n, with a pump E of any suitable type, as a reciprocating, rotary, entrainment or other type, but is preferably -a'second ejector, which further raises the pressure of the fluid,.as air, which is not condensed in the tubes Z. The ejector E may be of any suitable type, but is here in-- .dicated as of a type producing a diskshaped jet received into a surrounding annular diffuser, the motive fluid or steam though preferably of the type appearing in.

the' second stage, Fig. 8 of said Letters Patent.

The discharge from the ejector E is at 0, which may'deliver directly into the atmosphere or into any inclosure or region at any suitable or desired pressure.

Communicating with preferably the lowest point in the-chamber k is the pipe ,0 which descends, to form a U-tube water seal,

and then ascends and delivers at g into theinterior of the condenser shell J.

The mode of operation is as follows:

Steam entering at A and generally containing some uncondensable vapor and air, comes into contact with the jets of injection waterissuing from thenozzles or'apertu'res N'and is condensed thereby, the condensate and injection water fallingthrough the member D and collecting in the bottom of the shell J, as well understood in connec- .tion with jet condensers. There is carried with the mixture through the member D.un-

' condensed vapors and air which may be contained in the entering steam, so that within the shell J and above the water level- 03 thereinthere will exist. uncondensable vapors and air, sometimes increased 'b lea kage ofiair into said: space. In order t at the usual vacuum in the condenser. may be produced-and maintained, as Well understood in'connection with steam turbines and condensing engines, the uncondensable fluid must be removed from within the condenser,

and this is accomplished by theejector E,

or the ejector E and the pump or ejector EK' Steam or othersuitable motive fluid is. deiivered-to the ejector E-in well known man ner, and'thesame is expanded in a nozzle ornozzles which produces a jet or'jets entraining the air entering the suction 'chamber of the ejector E through-the opening into the/fluid passage 7' which delivers it into the chamber i," from which it passes through the tubes Z, in which the condensable fluid is condensed, and the condensate and uncondensable fluid, including air, is delivered into the chamber is, in which the condensate separates from the air, the con.- densate passing ofl through the pipe 12, to and. through the water seal therein, and is delivered at 9 into the body of water-within the shell J The uncondensed fluid including air in the chamber is, may now be delivered to any suitable point, and if at or above atmospheric pressure may be delivered directly into the atmosphere... But ordinarily, particularly where a high vacuum is to be maintained Within the condenser, the

' pressure of the uncondensable fluid including airabove the water in the shell J is in the neighborhood of. 28 or 29 inches of vacuum, as referred to the 30 inch mercury barometer. In such case the use of additional compressing means as pump or ejector E is desirable, and the vacuum in the com partment is may be, for example, 20 inches. I

Todeliver the uncondensed fluid or air" from compartment is to atmospheric pressure, it is further acted upon by the pump-or second ejector E which then delivers the air or uncondensed fluid at 0 directly into the atosphere or into any inclosure or region 1 at atmospheric or some other pressure.-

Thecondensing water, after having operated upon steam, may operate to condense the fluid from the ejector E after the water has been removed from the condenser by the pump P. Thus it will readily be understoodthat the tubes Z may be disposed in the path of the water removed and discharged by the pump P from the interior of the shell J.

It will be understood alsothat the tubes I Z may be disposed in the incoming injection water delivered to the chamber C, but such mode of operation, and structure therefor, is not herein claimed,'but is claimed in 'my ap lication Serial Number 271622.
