FLUID-COMPRESSING APPARATUS.

Application 'mea May a,

compressing fluid in a plurality of stages by action thereon by ejector apparatus'in one stage employing elastic motive fluid, as steam, the condensable fluid discharged by the first stage ejector apparatus being condensed, and the remaining fluid, as air, being acted upon in a later stage by any suitable pump, as ejector apparatus.

My invention resides in apparatus of the character referred to wherein the interstage condensing apparatus is of a structure making possible utilization of independent streams of cooling medium, as water, and more particularly, making possible utilization of streams of'cooling medium frem'different sources, as from the cooling system of a large or main condenser and from the condensate therefrom.

My inventionresides further in ejector apparatus combined with structure for condensing the condensable component of the discharge from the ejector passing through tubes subjected from within and without to cooling action; and my invention resides further in such apparatus in which the condensing structure employs independent streams of cooling medium.

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

For an illustration of some of the various 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 in-- vention.

Fig. 2 is a horizontal sectional view, partly in plan, on the line 2-2 of Fig. -1.

of the character illustrated in Fig. 1 i in combination with a maino r large condenser.

Fig. 5 is a vertical sectional-view, partly in elevation, of amodified structure embodying my invention.

Referring to Fig. 1, E is anejector, ofany prising the shell or body A and. the end boxes or chests 13,13 the aforesaid chamber 6 being one of three in the box B, as indicated in Fig. 2. These three chambers are formed by the transversely extending partition or wall f and the partition or wall 9,

the compartment 6 being formed between the partitions f and g. The compartment or chamber h isformed to one side of the partition f, and the chamber or compartment i is formed between the partitions f and g to the left of the latter, Fig. 2. Between the box 13 and the shell A is the tube sheet 7'; and between the shell A and the box B is the tube sheet is, compartments m and m being formed within the box B by the partition m The discharge from the.

ejector E into the chamber 0 passes through the vertical tubes 77. of the upper right hand group, Fig. 2, terminating at their :upper ends in the tube sheet 9' and at their lower ends in the tube sheet, k. The discharge passes into the chamber m and thence upwardly through the lower right hand group of tubes n, Fig. 2, into the chamber h, and thence downwardly through the lower left hand group of tubes a into the chamber m and thence upwardly through the upper left hand group of tubes 17. into the chamber 2' and outwardly through the discharge conduit 0 to the suction ofany suitable pump, as for example, the second ejector E whose discharge is at p.

Within the shell A between the tube sheets interior of the shell A into completely i11- dependent cooling waterpasses, the pass to the right of the partition 9, Fig. 3, cooling the tubes of the upper and lower right hand groups, while the pass to the left of the partition q cools the tubes of the upper and lower left hand groups, as viewed in Figs. 2 and Intersecting the shell A substantially at right angles to the partition 9 is the second wall or partition 1', whose upper edge forms a tight joint with the tube sheet 7', but

whose lower edge is spaced from the lower tube sheet is. The cooling water for the right hand pass enters at 8, passes around the tubes of thefirst group downwardly under the edge of the partition 1', and upwardly in contact with the tubes of the second group and leaves by the outlet 25. Similarly, the cooling water for the left hand pass enters at u, passes downwardly around the tubes of the fourth group around the lower edge of the partition 1, and upwardly in contact with the tubes of the third group,

and discharges at o.

'- Referring to Fig. 4, C represents a main condenser, indicated as a surface condenser, into which condensable fluid, as exhaust steam from a turbine, engine or other source, enters at w and the condensate is delivered into the hot well or condensate outlet m.

The cooling water for the condenser C is delivered by pump P, driven by any suitable means, as'the electric motor M, through the pipe y to the interior of condenser C, and

is discharged at the cooling water outlet 2.,

Part of the cooling water delivered by the pump P is diverted through the pipe a controlled by valve 0 to the cooling water inlet u of the auxiliary or interstage condenser A, passes through the condenser A as above described. and is discharged through the outlet o into the pipe b which may discharge into the main condenser cooling water outlet 2.

Driven by any suitable means, as by the same motor M, is a condensate pump P which withdraws the condensate from the condensate outlet or hot well an, and all or any suitable fraction of such condensate is delivered by the pump P through the pipe 0 to the cooling water inlet 8 of the interstage condenser A, such condensate passing through the interstage condenser A as above described. and discharges at t into i -piped, which delivers the condensate to the steam boiler feed water heater or pumps,

- ,or to any other suitable or desired destination.

The suction a of the ejector E communicates through a valve 0 with the air outlet f of the main condenser C. The ejector E lherefore withdraws air or uncondensable elastic fluid from the condenser C for maintaining the usual or desired vacuum thereln. The Withdrawn air in mixture with the steam or other motive fluid from the ejector E is then discharged into the compartment 6 of the interstage condenser, the mixture passing through the groups of tubes as above described, and the uncondensed remainder delivered from the connection 0 to the sec ond stage pump or ejector E The mixture from the ejector E in passing through the interstage condenser is first cooled by the condensate from the main condenser C and then is subjected to further cooling by the water delivered by the pump P through the pipe a Ordinarily, the condensate from the main condenser C will be of higher temperature than its cooling water, and accordingly, in the interstage condenser A the discharge from the ejector E is first brought into heat transfer relation with cooling water of higher temperature and then later with cooling water of lower temperature.

In passing through the groups of tubes in the interstage condenser, the motive fluid or other condensable fluid is 'more or less completely condensed, the condensate collecting in the chambers m and m in the lower box B From these the condensate passes ofl. through'the pipes and h controlled, respectively, by valves '5 and j these pipes delivering into the pipe 12 which delivers into a vacuum trap m which delivers through the pipe 0 into the condensate draw-off or hot well 00, or to any other suitable destination. lVhen the condensate discharged by the pipe p is delivered into the condensate draw-off or hot well :0, it becomes or may become cooling me dium for the interstage condenser entering at s and discharged at 6.

Referring now to Fig. 5, there is shown an interstage condenser structure of modifled form comprising the body or shell D having at its upper and lower ends the tube sheets 7' and 7c, in which terminate the vertical tubes at disposed in four groups. Above the uppertube sheet 7' is a box or chamber F, whose upper wall is formed by the tube sheet 7), which also forms the lower wall of the box or chamber B. Similarly, below the tube sheet is a box or chamber F 1 whose lower wall is the tube sheet 9 which forms also the upper wall of thelower box or chest B condensate being drawn off at 0 0 The upper chest F is divided into three compartments r 8 and t by the partitions a and o. The lower chest F 'is divided into two compartments 10 and m by the partition 3 One stream of cooling water enters the shell D through the inlet u, controlled by valve structure V, and leaves at the outlet 11, it being understood that the connections a and 1) may be in the cooling water system of the main condenser, .as indicated in Fig. 4. In passing through the shell D, the cooling water passes downwardly under the edge of the partition .2 thence upwardly and across the upper edge of the partition (1 thence downwardly and around the lower edge of the partition if, and thence out through the discharge '0.

By this action the tubes a conducting the ejector discharge are cooled on their outer surfaces by the cooling water entering at u and discharging at 'v. The ejector discharge is, however, cooled by the second source of cooling medium which is conducted through the pipes or tubes terminating in their upper ends in the tube sheet f and in their lower ends in the tube sheet 9 The upper chest B is divided into three compartments, d 0 and f by the partitions and k and the lower chest 13 is divided into two compartments and j by the partitiofi'lc". Cooling water, from any suitable source, for example from the condensate pump P of Fig. 4, is delivered into the inlet 8 past the flap valve a into the chamber (Z thence through the tubes 0 extending through the first named tubes n, discharging into the chamber i thence passing upwardly through the second group of tubes 0 into the chamber 6 thence downwardly through the third group of tubes 0 into the chamber thence upwardly through the fourth group of tubes 0 into the chamber f to the discharge outlet 25.

Thus, it will be understood that cooling water in two separate and independent streams, as in Fig. 4, or otherwise, passes through the condenser structure, one stream cooling the outside of the tubes 11 and the second stream cooling the ejector discharge from within the tubes at, the second stream of cooling medium being conducted through .tubes disposed within the first named l'--ll)8S,

and the ejector discharge passing through the annular space between the inner and outer tubes.

Inasmuch as the amount of condensate from the condenser C, Fig. 4, may vary with variations in load, the amount of condensate delivered through the inlet 8, Fig. 5, may vary. To ensure that there shall always be sufficient cooling medium applied to the interstage condenser structure, the flap valve 11?, responding to the incoming current'of condensate through 8, controls the valve structure V, so that as the amount of condensate entering at 8 increases, the valve structure V will be completely closedor moved toward closed position and so diminish the amount of cooling water entering at u; and vice versa, as the condensate from the main condenser diminishes, the valve 'V.

will open or admit more cooling water through the system whose inlet and outlet are u and '12.

It will be understood that in the structure of Figs. 1 to 4 inclusive there maybe disposed in one cooling water conducting system a control member like member a of Fig. 5 controlling a valve, like valve V, Fig. 5,

controlling the cooling medium in the other conducting system.
