Application filed October 8, 1917. Serial No. 195,315.
To all whom it may concern: g
Be-lt known that'I, RAY onD .LT. Enunner, a cltlzen of the Unltedstates, and a resident ofEdgewood Park, inthe county of Allegheny and State of Pennsylvania, have made a new and useful Invention in Ejectors, of which the following is a specifi cation. 7
This invention relates to ejectors andhas steam actuated ejector 'in which a simple condenser or intercooler is employed between stages and improvedmean s are employed for withdrawing the cooling witer employed in said intercooler.
A further object is to produce a multistage ejector in which a new and improved condenser and separator are employed between stages for condensing the condensable fluids discharged from one stage and for separating and withdrawing thecondensed fluids so that the subsequent stage of the ejector handles only non-condensable fluids and vapors. V
These and otherobjects are attained by means of an ejector embodying the features herein described, and illustrated in the; drawings accompanyingand forming a part hereof.
At the outlet or divergent end of the diffuser 12,1 have shown an intercooler or condenser of the jet type having a centrally located group of nozzles 13 which receive cooling water through an inlet pipe or passage 14 and which discharge it in finely divided form into and through a combining cone 15. The mixture of fluid and steam discharged by the initial stage 5 is intimately mixed with the cooling water in the combining cone l5, and the steam and other condensable fluids are condensed.
The coolingwater, the condensate and the uncondensed fluids and vapors pass through the combining cone 15 into a separator or trap 16 which, as shown, comprises, an open receptacle serving as a baths and receiver in which the liquids are brought to rest so that the air and other non-condensablc fluids andvapors may separate out. The receptacle 'l6tis surrounded by a casing 17 which. forms an open and tree means of communication between the outlet of the first stage 5 and the inlet to the second stage 7.' As shown, a passageway 18 is formel between the receptacle and the casing which establishes communication between the outlet of the combining cone l5 and inlet to in the condenser and the intercooler.
at the inlet to the second stage and are in clined so as to discharge a conical jet of steam into the converging end of a converging diverging diifuser 22, which forms a portion of thesecond stage. The fluids issuing from the first stage are entrained by the conical jet of steam issuing from the nozzle 19, and the velocity energy of the mixture of steam and entrained fluid is converted into pressure energy in the passage through the diffuser 22, which is so designed that the pressure of the mixture raised to that existing at the outlet of the difi'user.
As illustrated, the water and condensate collected in the receptacle 16 may be withdrawn through a lateral conduit 23 by any suitable means.
ll here the ejector is employed for removing air or non-condensa-ble fluids from a condenser, I preferably discharge the cooling or condensed water employed in the intercooler into the condenser by taking ad vantage of the differences in pressures with- In order to prevent air or non-condensable fluids from passing into the condenser from the intercoolcr, I employ a manometric connection 23 between the intercooler and the condenser which is capable of delivering water to the condenser and of preventing the delivery of air or non-condensable fluids from the intercooler to the condenser. In the drawings I have illustrated the ejector in connection with a portion of a condenser 24?. The inlet 8 of the ejector connnunicates with the air oiitake port of the condenser and th receptacle 16 of the inter-cooler communicates with a U-shaped pipe or passage 23 which, in turn, comn'uinicates with a port formed in the shell of the condenser. The pipe so formed that the legs of the U- shaped portion are of suflicient length to provide for a column of water of sufiicient head to counterbalance the diflerences in pressure which may exist within the intercooler and the condenser 24. lVith this arrangement, the water collected by the receptacle 16 is delivered to the condenser 24: and forms a seal between the condenser and the intercooler which prevents air or non-condensable gases entering the condenser from the intercooler.
In the ejector illustrated the work of the second stage is reduced to a minimum because the quantity of fluids it must compress is reduced substantially to the quantity of non-condensable fluids and vapors initially drawn into the ejector. As a result the second stage may be small as compared with the second stage of an ejector not provided with an inter-stage condenser. The condenser and the trap are simple, compact and eliicient. in the inter-cooler or condenser 6 may ad- The cooling water employedvantageously be condensate withdrawn from the main condenser 2st.
lVhile I have illustrated and described but one embodiment of my invention, it will be apparent to those skilled in the art that various changes, nodifications, additions and omissions may be made in the appa atus illustrated without departing from the spirit and scope of the invention as set forth in the appended claims.
