BOBERT SUCZEK, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO C. H. WHEELER MANUFACTURING COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORA- 'rIoN or; PENNSYLVANIA.

METHOD OF AND APPARATUS FOR COMPRESSING- FLUID.

To all whom it may concern:

Be it known that I, ROBERT SUGZEK, a subject of the Emperor of Austria-Hungary, residing in the city of Philadelphia, county of Philadelphia and State of Pennsylvania, have invented certain newand useful Improvements in Methods of and Apparatus for Compressing Fluid, of which the followin a is a specification.

y invention relates to a method of and apparatus for compressing elastic fluid, such as air, gas, vapor, or a mixture of them, and

, involves the ejector principle in accordance with which a motive fluid entrains the fluid to be compressed, and after entrainment diminishes in velocity while rising in pressure. I

It is the object of my invention to provide elastic fluid compressin apparatus operating upon the aforesai ejector principle, whereby the efficiency shall be materially improved by employment of a plurality of nozzles coiiperating with a diffuser common to them, the nozzles producing closely adjacent parallel or intersecting ets of motive fluid, which may be in the orm of sheets and which are preferably stepped or overlapped, the fluid to be compressed being detive fluid jets an livered toward the motive fluid jets in the form of a jet or sheet, all the jets, being delivered into the difiuser, which is suitably ajined or positioned with respect to the nozz es.

And my invention resides in'a method of compresslng elastic fluid by motive fluid, the latter taking the form of a plurality of closely adjacent parallelor intersecting jets or sheets, the latter preferably stepped or overlapped withrespect to each other as re-,

gards their longitudinal. movement, the elastic fluid to be compressed'beingadmitted in a sheet or jet su erimposed upon the moentrained thereby, the mixture diminishing in velocity and increasing in' pressure; and by preference the jet or sheet of elastic fluid to be compressed is isolated from one side of the motive fluid mass, a jet or sheet of which latter is directe'd along or closely adjacent to a wall of the difiuser.

For an illustration of'some of the forms my apparatus may take, and for an understanding of my method, reference may be Specification of Letters Patent.

Fig. 5 is a fragmentary cross sectional,

view of a discharge casing with adjuncts, for any of the types of apparatus herein described, and for general application wherever suitable, wherever condensing water is admitted.

Fig. 6 is a fragmentary cross sectional view taken at ri ht angles to Fig. 5.

Referring to ig. 1, there is illustrated single stage ejector apparatus in which B and B are circular or annular nozzle passages for the motive fluid, which if elastic, as in the case of steam, is expanded therein. The nozzle passage B is formed between the wall or nozzle member to and the circular nozzle member C and the' passage B is formed by the member G and the circular nozzle member C. The member C is disposed upon the end of the stem a screw threaded at 8 through a wall of the air inlet chamber A rotation of the stem 0 causing adjustment -of the nozzle member C to the right or left. The codperating nozzle member C is disposed upon a stem 0 screw threaded at 8, through a wall of the steam inlet chamber'A, rotation of the stem 7 0 serving for adjustment of the member C to the right or left. The stem 0 is hollow,

at least at the end adjacent the member C and has a plurality of ports ;0 communicating with the steam inlet A, these ports preferably being of ample area so that there shall exist within the stem 0 steam pressure substantially ual to that in the steam inlet chamber A. The stem '0 is supported in the 'de. g supported by a plurality of circum erentially spaced r1bs r, the space v at least great enough so that there shall exist to the left of them a steam pressure substantially equal to that in the steam inlet chamber A. Between the member C and the member w is the annular throatT of the nozzle B. At its center the member G has the throat T for the nozzle annular diffuser compr' B the nozzle member C having a projection t extending toward or into the throat T.

Common to the nozzles B and B, is the the side wall members H and H of WhlCh the latter is shown. straight, as indicated, and wall H is inclined, as shown, the diffuser having a throat at t,. The difl'user delivers into the dischar e casing F. which has the discharge outlet The difi'user'wall H may be inte ral with or suitably joined to the air in et chamber A,, 'which'by its flange f may be connecteddirectly or indirectly through suitable connections to the chamber, as a steam condenser, fronrwhich the compressible fluid, as air or vapor, is to be removed orin which a hi h vacuum is tobe main- A commu- B and B tained. The air lnlet chamber nicates at the left of the nozzles with the common diffuser.

While the-nozzles B and 'B are adjustable independently of each other by the stems-0 and 0,, the crosssectional area of' the diffuser may also be ,changed, as by inserting or removing one or more of gaskets The mode of operation is as follows: With steam at any suitable or desired pressure delivered to the common steam inlet chamber A, steam passes at the same pressure through throats '1 and T into their respective expansion nozzles B and 00' with the air inlet chamber A The air B in and by which it is expanded in jets in the form of sheets moving'substantiall radially outward, in the example illustrate the sheet from the nozzle B passin along the inner wall of the difluser memer H and the sheet from the-nozzle B passing in' arallel plane or direction,

a substantially more or'less conical, as

tance from the outlet or mouth of the nozzle B, that is, the closely are, in the example illustrate diameters.

Similar] the air or elastic fluid to be compresse is drawn in a jet or sheet from a nozzle-like structure whose throat is indicated at the region t,. in communication adjlacent nozzles jet orsheet is in effect superimposed upon the motive fluid jets and is entrained by the latter, the resultant mixture of air and motive fluid advancing through the conthe motive fluid inlet is onthe other, and

- fluid jets from that side.

'celeration of the air,there is 'available,how-

refore intersect the sheetof difierent sultabl verging portion of the common difl'u ser H,

H to 1ts throat t 'with resultant increase in pressure attained at the expense of loss of velocity. The mixture is then discharged into the casing F and delivered at atmospheric pressure or any other desired pressure through the 'outlet'F By the construction illustrated, the air inlet is on one side of the diffuser, while 75. the motive fluid jets are formed between the two, the structure afiording a uni-lateral admission of the airto the motive fluid Ijets, since the jet from the nozzle B passes along the wall H, of the diffuser, and accordmgly' no air is admitted to the motive The auxiliary jet from the nozzle vB is preferably relatively longer than the main jet from nozzle B,giving longer time, and therefore requiring less ener to accelerate the incoming air to: suitably" high velocity before coming into entraining relation with the main jet from nozzle B. Furthermore, while attaining such preliminary acever, forthe final compression a relatively shortnon-dispersing highly penetrating jet from the nozzle B. i

In Fig. 2 two apparatusof the general character illustrated inFi 1 are shown connected in series for dou 1e stage operation, whereby operation is possible at high .total ratio of com ressi on, as for example in excess of 60. din such double stage arrangement the ratios of compression in the different stages may be made equal or unequal as desired as by making the ratio of compression in thefirst stage equal to the ratio of compression in the second, or by making it less or greater.

It will be understood, however, thatthe ejector apparatus of either one of the stages may be of a different type than herein disclosed, and may be of any suitable type in which the motive fluid is elastic or a liquid,

as water. I

There is .illustrated in F' 2 further structure which is also availab e in connection with that shown in Figs. 1 and 4, com- Brising the annular air conducting member the o"ening in which decreases in cross section rom the air inlet chamber A to.- ward the steam jets. This'member may be adjusted toward the right or the left by adjusting the screws 8,, 8,, as by j partial y withdrawing one and advancing the other. By such adjustment the cross sectional area of the annular air throat at t, may be adjusted to'suit various operating conditions. i

The discharge outlet F of the upper orfirst sta e delivers into the intake chamber- A. of t e second stage, the mixture of air and motive fluid then being operated upon in the second stage, 'as described in connection with Fig. 1, and raised in pressure and delivered .to the discharge casing F which has the discharge outlet F 3 to atmospheric pressure or any other desired pressure.

In both Figs. 1 and 2 the nozzles B are of larger diameter or longer than the nozzles 13 and it is preferred that the thickness of the jet from the nozzle B shall exceed that from the nozzle B In Fig. 3 is shown a structure similar to those hereinbefore described, in that the nozzles all discharge into the common "diffuser H Here again the nozzle members are indicated at C and C the motive fluid being delivered to the passages I and I from a common steam inlet as before, if desired, while-the air or fluid to be compressed is drawn in through the passage I In this structure the nozzle members C and C, differ in their diameters to greater extent. And while my invention is not limited thereto, in this structure the annular diffuser H is to some extent conical and in alinement with the nozzles.

In Fig. 4 is shown a single stage apparatus of the same general character in which the nozzles B and B are of substantially the same diameters or lengths, and the jets produced thereby are substantially equal in thickness. And in this case both walls II and H of the diffuser are inclined, the steam inlet A in this instance being at the left and the air inlet A at the right.

As illustrated in Figs. 5 and 6, there may be disposed upon the discharge casing F of any of the ejector apparatus herein disclosed, or any other type of ejector apparatus having similar discharge casing, an annular or circumferentially extending chamber E into which water or other suitable cooling liquid is delivered through one or more passages G. Communicating with the chamber E is a circumferential seriesof injection nozzles n through which cooling liquid 'is delivered into the casing F, where it operates upon the motive fluid, as steam, to condense the same, the latent heat of the steam serving to raise the temperature of the water which may be utilized for any suitable purpose, as for example, the feed water of a steam boiler. I

It will be understood that the proportions of the various nozzles, diffuser, etc., of my apparatus will be varied separately or collectively to suit various operating conditions. I

By the method and structure ofthe character herein described, elastic fluid may be compressed in a single stage apparatus to a pressure whose ratio to the pressure of the fluid before compression is 30 or more; and in double stage the ratio of compression at tainable is and hlgher.

The method and apparatus may be employed for removing air from a steam condenser; in connection with a refrigerating or other suitable liquid; or steam or any other suitable elastic motive fluid, as air, vapor, or gas, or a mixture of them, under suitable pressure. And where steam is employed as the motive fluid, it may be live steam of any suitable pressure; or it may be exhaust steam from engines, turbines, etc., which may be of a pressure even below 1 atmospheric.
