FLUID-GUMPR ESSING PATHS.

a lication filedl Na e,

in the city and county of PhiladelphiaJState "of Pennsylvania, have invented certain new and useful Improvements in Fluid-Compressing Apparatus, of which the following is a specification 1 My invention relates to apparatus for compressing fluid in a plurality of stages by action thereon by ejector apparatus, in one stage employing condensable motive fluid, as steam, the condensable fluid discharged by the first stage ejector apparatus. being condensed and the remaining uncondensed fluid, as air, being acted upon in a later stage by any suitable pump, as .an ejector. j

My invention resides in apparatus of the character referred to wherein the interstage ing possible the utilization of independent streams of cooling medium, as water, and. more particularly, making possible utilization of streams of cooling medium from ditterent sources, as from thecooling system'of a main condenser and from the condensate therefrom v My invention resides further in apparatus of the character referred to wherein separate portions or units of the heat transfer structure, as separate groups of condenser tubes, are subjected to independent streams of cooling medium.

My invention resides further in apparatus of the character referred to wherein means are provided for automatically controlling the independent streams of cooling medium andproportioning said streams relatively to each other.

My invention resides in the features at construction and combination hereinafter described and claimed.

For an illustration of one otthe forms my invention may take, reference is to be had to the accompanying drawings, in which:

Fig. 1 is a vertical sectional view, partly in elevation, of. apparatus embodying my invention. 1;

, Fig. 2 is anelevational view of the apparatus illustrated in Fig. ,1, in combination with a main or large condenser.

Referring to Fig. 1, E is an ejector of any 1192c. seriainu. static.

suitable type, here cantata as or the tubular type, whose suction port, a, communisel or region from which elastic fluid is to be withdrawn and compressed. Elastic motive fluid, as steam, is supplied to the nozzle structure of the ejector E, through pipe b, controlled by valve C. .The diffuser 02 ot ejector Fl delivers into the con- -cates with the main condenser or other ves-' densing apparatus Condensing apparatus M comprises two units A and B. Upper unit A comprises upper and lower tube plates 9 and in supporting the condeser-tubes Supported between the tube plates g and h and surroundingitubes leis the cooling Water jacket or shell L having cooling water inlet .m, and. cooling water, outlet at, both communicating with shellli adjacent the 'upper tube plate 9. Extending down wardly from tube plate 9' within shell L is a bathe plate '5, terminating short of tube 7 plate It and dividin the cooling water chamber formed by tu e plates 9 and hand 1 shells L into two compartments 9 and 1".

tubes is, above tube plate g, is a chamber Communicating with the ends of condenser I 'C-divided into compartments 0 and f by apartitionp. Compartment 6 receives the discharge from ejector E and communicates with the condenser tubes 7:: in'chamber r of the cooling water jacket. The chamber 7' communicates with the, condenser tubes It in chamber 4 of the cooling water jacket,

, and through conduit K with a second ejector E I Condenser unit 'B, is similar to unit A.

having upper and lower tube plates 9- and k condenser tubes k cooling water jacket or shell L cooling water inlet and outlet m i and 02 and baflie i dividing the cooling Water jacket into twochambers g and 7.

On the lower end of condenser unit A, secured to lower tube plate It, is a shell 0';

divided into two chambers or conduits sand't communicating, respectively, with the condensertubes 7c in chamber q and the condenser tubes k in chamber 9' of the cooling water jacket or shell L. The upper end of condenser unit B is provided with a shell 0 having two conduits s and t communicating, respectively, with conduits s and t and with condenser tubes 70 in chambers g and at of coolingwater jacket L 0n the lower end of condenser unit B is mostat T subjected to the a chamber C communicating with con denser tubes k and with the condensate conduit j, the latter controlled by valve o.

Referring to Fig. 2, the intake (1 of ejector 1E communicates through pipe a, controlled by valve m, with the large surface condenser D having inlet w for fluids to be condensed and a condensate discharge pipe N. Cooling water is supplied to condenser D through pipe 3/ by means of pump F, operated by motor Cr, and discharges from the condenser through pipe 2.) Communicating with pipe 3 intermediate pump l3 and condenser D, is a cooling water pipe y controlled by hand valve '20 and thermostatic valve V and discharging into cooling water intake m of condenser unit B. The cooling water outlet n or condenser unit B connects through pipe 2 with pipe 2.

Condensate discharge conduit N from condenser D discharges into the intake H, operated it desired or convenient, by motor G. Pump H discharges through pipe N into the cooling water intake m of condenser unit A, the cooling water outlet n discharging to waste, or preferably to the boiler feed water tank.

The condensate discharge conduit j connected with the bottom of condenser unit B leads to the intake ot pump H through a vacuum trap T and pipe N.

Thermostatic valve V is controlled by thercooling water in chamber r of condenser unit A.

The operation is as follows:

W'aste steam mixed with uncondensable gas, as air, from any source, as a steam engine, is discharged into condenser D where the steam is condensed by contact with heat transfer structure cooled by cooling water supplied by pump Gr through pipe 3, and leaving the condenser through pipe 2. The unconden seol fluid from condenser D passes through pipe u to the intake a of ejector E, wherein it is ejected by motive fluid, as steam, supplied through pipe 6, and discharges through diffuser al into compartment e of chamber C on condenser unit A. From compartment e the mixture of uncondensed fluid and motive fluid passes through condenser tubes k in chamber 1 downwardly throu h conduit t of shell 0 and conduit t of she I 0 into condenser tubes of chamber a. .lLeaving the latter tubes 70 the gases pass through chamber C and upwardly through condenser tubes isin chamber g, on through conduits 8 and a in shells 0 and 0 into condenser tubes it in chamber 9' from which they discharge throu h compartment f and conduit K to the inta e of pump or ejector E Condenser tubes k in condenser unit A are cooled by condensate leaving the condenser D through pipe N, said condensate passing of pump.

pump H, pipe i 1 and through chambers g and 1*, respectively, to waste. Condensate from both condenser units A and B collecting in chamber C flows through pipe j and trap ll into pipe N, from which it also is passed through chambers g and r of condenser-unit A. All of the condensate is thus employed as cooling medium for condenser unit A. While I have here shown the use of condensate as cooling medium for unit A, it is to be understood that my invention is not limited thereto, and cooling medium from any other source may be employed.

Cooling medium, as water, is supplied to condenser unit 13 from the discharge of pump F passing through pipe y, chambers and r respectively, of condenser unit B, and discharging through pipe 2 into pipe 2.

In order to save cooling water or use as little thereof as possible, the cooling medium, as condensate water, supplied to condenser unit A is utilized to its fullest extent and only sufficient cooling Water is supplied to condenser unit B to complete the condensation. and thermostat T are adjusted to supply the requisite quantity of cooling water to con denser unit B. If the amount otheat to be absorbed by the cooling medium in condenser unit A decreases, or the supply of condensate water employed as or its temperature decreases, the thermostat T and valve V operate to reduce the supply of cooling Water to condenser unit B. H, on the contrary, the temperature of the cooling medium in condenser unit A increases, then thermostat T and valve V operate to increase the supply of cooling water to condenser unit l8. Thus, the supply of cooling water is always sufi'icient, but not in excess from pipe N through of that necessary to accomplish complete or any desired predetermined degree of condom sation.
