To @ZZ wwm it may concern:

Be it known that l, ROBERT Suomen, a citizen of the CzechdSlova-lr Republic, residL ing in the city and county of Philadelphia,

t State of Pennsylvania, have invented certain new and useful improvements in Fluid- Compressing Apparatus, of which the iollowing isa specification.

My invention relates to apparatus for comm pressing fluid, such as air, gas, vapor, or a mixture of any of them, by ejector action, that is, by the action of motive Huid, such as steam or other elastic fluid under pressure, which is allowed to expand and entrain the M fluid to be compressed, the mixture of Huids travelling at high velocity losing its kinetic energy and increasing in pressure.

My invention relates more particularly to apparatus for compressing duid in a plu- 2@ rality of stages by'action thereon of motive fluid in one stage, the condensable Huid from that stage being condensed, the condensate removed, and the compressed liuid, as air, being acted upon in a later stage by any 2U suitable pump, as a second ejector, further to raise its pressure.

ln accordance with my invention an ejector delivers into the condenser in which there are provided means for ensuring sat- 3@ isfactory and substantially complete separation of condensate from the fluid, as air, undergoing compression. A Jfurther feature of my invention is a structure of the condensing structure in relation with'the ejector VE wherein the mixture discharged from the ejector is passed through a plurality of tubes or passages, extending vertically or substantially so, the condenser having a plurality of passes, permitting the apparatus to taire au larger diameter or'shorter vertical length or height.

A further feature of my invention is the withdrawal of condensate from the end of each pass or group of'condenser tubes.

i5 A further feature of my invention resides in an arrangement whereby condensate at the upper end of a pass ongroup of condenser' tubes is prevented from passing downwardly through the tubes conducting' the air or other Huid which has undergone compressiong-and a further feature resides in the application of drain pipes as hereinafter described and in the structure of such drain pipes and the* A ture.

Referring to the drawing, T. is an ejector oi any suitable type or structure, Vand in the example here illustrated is a tubular ejector comprising the motive duid en ending noszles N, the tubular converging iverging dit user D, and the suction chamber t having the suction port al through which enters the air or other duid to be compressed, as for example, from a steam condenser or irom any other chamber or region trom which the air or other compressible iluid is to be withdrawn. Steam or other suitable motive duid is supplied to the nozzles N through the pipe o; controlled by valve l and delivering into the chamber c with which the nozzles lil communicate. The ejector L@ is mounted upon boi: or chest B which is divided by the walls or partitions CZ and e into the three chambers f, g and iz. These chambers have a wall formed by the tube sheet or plate e held between the bon B and one end or" the condenser shell C. Within the shell G are the downwardly extending plates or baes i and and the upwardly extending plate or baille l, these plates or baos dividing the interior of the condenser shell C into tour. passes in which are disposed tour groups of tubes m, ot brass or other suitable material secured by terrines n in the tube sheet a' and the lower tube sheet o held between the condenser shell U and the lower chest or box B1. The condenser structure is supported upon legs L, L, extending downwardly from box B1. By pipe threaded into the con denser shell 'C at p is delivered cooling Huid, as water, Howing' downwardl to the left et the plate or bams j',under its lower edge then upwardly around the next group ci tubes over the upper edge oi the plate or titl 'lll

baffle Z, then downwardly between the next group of tubes under the lower edge of the baffle or ,plate lo and thence upwardly through the next group of tubes and outV through a pipe connecting to the condenser shell at g. With each of the second, third and fourth groups of tubes is associated one of openings o communicating with the space between the cap u and the exterior of the tube t.

The ferrules employed in connection with the upper ends of the condenser tubes lof the second, third and fourth groups are, as indicated in Fig. 1, at lw, of substantial length, thereby extending a substantial distance above the upper surface of the tube sheet i to prevent any water or condensate accumulat-ing from entering the condenser t'ubes m.

In the lower chest or box B1 is the dividing partition or diaphragm a: preventing equalization of pressure or other conditions as between the lower ends of the tubes of the first two groups and the lower ends of the tubes of the third and fourth groups. Communicating with the two chambers in the chest B1 are the pipes g/ and z, controlled, respectively, by the valves a1 and b1 and delivering into any suitable pipe or draw off c1 to deliver the condensate to any suitable device or region, as for example,

delivering the condensate into the steam or` condensate space of the steam condenser with which the ejector apparatus may be associated for withdrawing air or uncondensable gases or fluids therefrom.

In order that the chambers in the box or chest B1 on opposite sides of the partition m shall remain sealed from each other, the pipe c1 with which the pipes y and z communicate rises to any suitable level, as c2, whereby there is formed a U tube structure in which water is retained to such level as to rise somewhat above the lower ends or outletsof the pipes y and a, that is, to height somewhat above the level c3, so that a mass of water is continuously maintained in the pipes y and z sealing them against each other and thereby preventing communication through pipes y and a between the two chambers on opposite sides of the partition m in box or chest B1.v

The chamber k in the chest B communicates through the conduit d1 and the divided passages e1 with the suction of the radial ow ejector E1, comprising the nozzle struc- Lecoas ture N1, producing a disk-shaped jet, and the surrounding annular diifuser structure D1 delivering into the discharge passage f1 having the discharge outlet g1. The ejector E1 may be wholly or partially supported by the condenser structure through its connection therewith. Steam is delivered to the nozzle structure N1 through the passage k1 communicating with the steam delivery pipe 1, with which communicates also the aforesaid steam pipe a.

The operation is as follows: Y

The air or other fluid to be compressed enters -at A1 into the suction chamber A of the ejector E, where it is acted upon in known manner by the steam issuing in jets from the nozzles N and delivered at high speed into the diffuser D where kinetic energy is converted into pressure, the mixture of motive fluid and steam and the air arriving inthe chamber f at a pressure higher than that of the air entering at A1. The mixture paes downwardly through the condenser tubes m around which is flowing the cooling water, causing condensation of the steam, the condensate or water together with the partially compressed air flowing downwardly through the pipes m intoone of the chambers in the chest or box B1, the condensate remaining in such chamber and passing oi through the pipe z while the air continuesv its paage upwardly through the condenser tubes m of the second group, where it is further 'cooled and more steam or motive fluid condensed, the. air passlng on upwardly into the chamber.

g while the condensate drips downwardly through the pipes m into the aforesaid chamber in the box or chest B1, passing .off

through the pipe z, as described. The air and remaining steam vthen descend throu h the tubes m of the third group from t e chamber g into the left hand chamber in the box or chest B1, the condensate then passing olf through the pipe y. Finally the air ascends again through the fourth group of tubes m, any remaining motive fluid or condensable vapor being condensed and running downwardly through the tubes m of the fourth group intothe chamber of the box B1, and passing oli' through the aforesaid pipe y. The air arriving in the chamber 71. is free or substantially free of motive fluid or moisture or vapor and passes to the suction chamber of the second stage ejector E1, whereby the action of the' steam from the nozzle N1 it is further compressed in the annular diiuser structure D1 and delivered at higher pressure into the discharge casing f1 and thence through the outlet g1 to atmosphere or into a chamber or region at any other suitable pressure.

While an ejector E1 is shown in the second stage, it will be understood that my invention is not limited tothe use of an ejec- 8.
