CONDENSING APPARATUS.

Original application iiled March 8, 1917, Serial No. 153,454. Divided and this Serial No. 195,904.

To all 'whom z't man concern.'

Be it known tat I, Roiiiinr SUCZEK, a subject of the Emperor of Austria-Hungary, residing in the city of Philadelphia, county of Philadelphia, and Stute of Pennsylvania, have invented certain new and useful Improvements in Condensing Ap aratus, of which the following is n specification.

My invention relates to jet condenser apparatus wherein, as well understood in the art, cooling water comes into direct contact with the steam or other vapor which is to be condensed.

In such ap aratus it is common to employ n centriiiigal pump for removing all the liquid, comprising both the injection cooling water and the condensed vapor or steam, the pump generally being submerged in the water in the bottom of the apparatus. Such a removal pump removes not only the water referred to, but also considerable air existent in the injection water and in part, the air entering the condenser with the steam. In association with such apparatus it is common also to employ an air pump of any suitable type for removing air or uncondensable gases to maintain n vacuum higher than would be possible by the einployment of the removal pump alone.

It is the object of my invention to cause the removal ump to remove n greater proportion of t e nir and tuereby reduce the amount of air to be removed by the nir pump. To this end I provide one or more ducts, conduits or pipes communicating with the Suction inlet of the pro eller of the ccntrifugal pump and extending into the liquid collecting chamber of the condenser to a point well above the level of the liquid therein.

For an illustration of one of the various forms my invention may take, reference is to be had to the accompanying drawin,

Referring to the drawing, J is the bo` y of the jet condenser which receives through the opening E the steam or other'vapor bo be condensed. Surrounding the body .I is the water distributing chamber C receiving the cooling or injection 'water through the connection W. ln the Wall of the body J is formed n series of nozzles or openings .N through which the cooling water is in- Specication of Letters Patent.

application lllol October 1l,

jected into contact with the steam entering at E. The steam in contact with the I6 cooling water is condensed into water, and the in'etion water und condensate fall throng the cone, guide passage or difusor D into the bottom of the body J, when i3 risesto a level maintained above the uppeb M most level of the suction of the submcef impeller I of the centrifugal removal I. The impeller I is driven by tha S rotatin, in bearings B and drifen any suitabyle motor, as n steam turbine op C8 electric motor, not shown. The implltl I discharges into the volute discharge (Ilsing V, which delivers to any suitable point outside of the apparatus.

'ithin the body J are provided the tubes, ducts or nir conduits T extending above the variable liquid level A und communicating at their upper ends refernbly above the lower end of member ll) with the air spoed within the condenser and at their lower ends being deflected laterally at L and deliver ing at K into the suction orifices of and on opposite sides of the impeller I.

*ixtending into the lateral tubes L to a point approximatehtheir orifices K nre the pipes P2 terminating in the nozzles P.

Communicating with the nir space of the condenser is an opening O connecting through the pipe Q with an air removing pump G'of any type, as an entrainment pump, iin ejector, or the like.

The operation is as follows:

The im eller I by its rotutioin'iis well understood1 in the art, withdraws water from the bottoni of the bod J and delivers it into the volute or diedi/arge casing V, from which it is delivered to any suitable point exterior to the u paratus.

This water has entrained therein air originally entering with the injection wete! und u some of the air entering the condenser with the steam to be condensed.

More air may be removed, however, b use of the conduits or tubes T os indica in which case the impeller suction will draw nir from the air space of the condenser through the tubes T, thereby producing or assisting in producing n vacuum in the c0ndenser, and the air will pass into the impeller I with the water and be removed 105 therewith. By this action more air is Iomoved, and there is accordingly less load upon the air removing device connected This application is a division from my a plication Serial Number 153,454, lfiled arch 8, 1917.
