AUXILIARY APPARATUS FOR CONDENSERS.

Application filed April 18, 1922 Serial No. 554,512.

Top whom it may concern:

Be it-known that I, ROBERT same, a citizen otthe United States, ,residing in the city and county of Philadelphia, State of Pennsylvania, have invented certain neW i and useful Improvements in Auxiliary Apparatus tor-Condensers, of which the foll'ovvingfis a specification. My invention relates to apparatus for removing from a vessel, particularly one in which there is to be produced or maintained a vacuum, as a condenser or evaporator, elastic fluid, as air or gas, and liquid, as condensate or Water, by separate ejectors which discharge the air or gas and condensate orliqruid, respectively, through different or independent paths, to higher pressure or otherwise.-

My invention resides in apparatus of the character hereinafter described and claimed. For an illustration of one of the various forms my invention may take, reference may be had to the accompanying drawing,

,WlllCll is avertical sectional vieW through a portion of the condenser and associated apparatus for removing air and condensate.

Reter-ring' to the drawing, C represents the shell, of a condenser, for example, the shell of a surface condenser or a marine condenser such as used upon board ship to condense the exhaust steam from the engines or turbines. Both air and condensate are ivithdrawn through the outlet 0. The condensate collects in the hot Well or other receptacle H, the level of the Water or con-- den'sate being indicated at W. In the condensate is submerged an ejector comprising the nozzle N aligned With the combining cone or guide tube B, which in turn is aligned with the diffuser or other tube D communicating with the suction chamber S, of any suitable type, of pump P, which is indicated: as and preferably is a reciprocating Wet air pump. Through the pipe A,

7 controlled the valve -there is delivered undersuitable pressure to the nozzle N any suitable motive fluid, as'elastic motive fluid, as steam, or liquid, as Water. The motive fluidolelivered through the nozzle N causes the liquid or ,condensate to be drawn into themember Bi and to be delivered to the tube or difli'user D and discharged therefrom into the suction chamber S at higher pressure than obtains in the hot ell H.

The leaving the conde'nser'C through the openlng 0 passes upwardly to the ejector Whose nozzle structure is indicated at M and having the diffuser or equivalent D Me,- i

tive fluid of any suitable character, preferably steam of suitable pressure, is delivered by the pipe E, controlled by the valve an,

to the nozzle structure M, which delivers fa j etot' motive fluid which entrains the air, the

mixture being delivered to the ditfuserD at high veloclty. The velocity of the mixture decreases and is converted into pressure in the diffuser D and the mixture of steam and air is delivered either directly to the suction chamber S, or preferably, as in dicatechto a condenser 0 ,111 Which the motivecfiuid steam is more or less completely condensed, the condensate from the condenser C and the air passing onward to the suction chamber S, from Which the con- Vdensate, from both condensers and the air from the condenser C is removed by the pump P The ejectors deliver, respectively, the air and condensate or other liquid against or to I substantially the same pressure, to Wit, that existing n the suction chamber S. The pressures of both the air and the liquid or conden'sateare increased by the ejector's to a substantially equal or common pressure, the air and condensate being then removed "by the pump P upon Which the load ,is correspondingly less because of the preliminary compression ofthe air and increase in pres- A sure of the liquid orconde'nsate. The-ejectors in effect assist the pump P by preliininarily raising the pressure of the air and liquid or condensate.

While the ejectors herein disclosed are ot simple single noz'zlef types, it Will beunderstood that any suitable forms of ejector may be used, as for example, those employing a plurality of steam nozzle's, or ejectors having posed outside of and s'urroundsthe annular nozzle which discharges radially into the diffuser. The apparatus closed in Letters Patent of the United States No. 1,3&2,4t71, granted me JuneYS, 1920. v a i What I claim is z y 1. The combinationwith a annular nozzles and diffusers, or ejectorsofi; the latter type in which the diffuser 1s disherein disclosed is disreceptacle for liquid, of an ejectorsubmerged in the liquid, a second receptacle to which said liquid is delivered by said ejector at higher pressure, and 'a-se'cond ejector delivering fluid at increased pressure to said second receptacle inindependently of said first named ejector.

2. The combination with a receptacle for liquid, of an ejector submerged in the liquid, a second receptacle to which said liquid is delivered by said ejector at higher pressure, and asecpnd ejector delivering air at increased pressure to said second receptacle independently of said first named ejector.

3. The combination with a receptacle for liquid, of an ejector submerged in the liquid, a second receptacle to which said liquid is delivered by'said ejector at higher pressure. 'a. second ejector delivering air at increased pressure to said second receptacle independently of said first named ejector, and means for withdrawing the air and liquid. from said second receptacle and raising them to higher pressure.

4. The combination with a receptacle, of a steam-operated ejector discharging air at higher pressure, a condenser into which the ejector discharge is delivered and in which the steam is condensed, the condensate and air delivered into said receptacle, and a second ejector delivering liquid from lower pressure into said receptacle.

5. The combination with a receptacle, of a steam-operated ejector discharging air at higher pressure, a condenser into which the ejector discharge is delivered and in which the steam is condensed, the condensate and air delivered into said receptacle, a second ejector delivering liquid from lower pressure into said receptacle, and means for withdrawing the air and liquid from said receptacle and raising them to higher pressure.

G. The combination with a condenser, of

a receptacle for the condensate therefrom,
