GEORGE DE LAVAL, OF EAST ORANGE, NEW JERSEY, ASSIGNOR '10 HENRY R.
IORTHINGTON. A CORPORATION OF NEW JERSEY.
JET-CONDENSER.
Specification of Letters Patent.
Application led September 17, 1910. Serial No. 582,431.
1 as centrifugal condensers, although the broader features of the invention may be applied with discharge pumps of other forms, the object of the invention being to provideesimple and efficient means for removing the air thc condenser.
In the accompanying drawings forming a part of this specification, t-he invention is illustrated as applied in its preferred form, in connection with a counter-current con` denser, and this condenser will now be described in detail and the features forming the invention then particularly pointed out in the claims.
In the drawing, which is a vertical central elevation of the condenser, there is shown a countercurrent condenser of the general type of United States Letters Patent No. 899,063, in which A is the condenser shell, B the exhaust steam inlet, C the discharge outlet or tailpipe, D the injection or condensing water inlet, and E a series of inner and outer water spray forming trays through which the water passes downward from the inlet D to the tail pipe C at the bottom of the condenser and through which sprays the steam passes upward ior condensation. The tail pipe C terminates in the suction of the centrifugal discharge pump F having the impeller a and delivery chamber t) and preferably being direct driven by a small steam turbine G on the impeller shaft o. drawn in through pipe D by the condenser vacuum, and a force injection pipe D is shown for use in starting the condenser, or when otherwise required.
Referring now to the means for removing from the condenser the air and uncondensed vapor, II is a small pump, preferably a ccntrifugal pump with its impeller driven from the shaft c, as shown, which delivers water and uncondensed vapor from The injection water isl through a pipe I extending to and entering the top of the condenser, where it connects 1 Patented Nov. 1e, 1912.
with a pipe K extending downward centrally through the condenser. This pipe K has a contracted portion e which forms a water ejector, and 1s provided with openings l through which the air and uncondensed vapor 1s drawn .in-'tothe pipe K from the upper part of the condenser and y the water from pipe I downward through pipe K. Within the ejector e is shown and preferably used a small pipe d perforated within the ejector and communicating at its upper end with the space above the injection water openings 2, so that the ejector e through this pipe d will draw oil' any air collecting above the injection water inlet.
The pipe K in the preferred coiistruction shown delivers to the centrifugal pump F, so that the discharge water from the tail pipe C andthe water from air pipe K are delivered by a single pump. In the construction shown, the pipe K communicates with a chamber f surrounding impeller a and the impeller' is provided with outside vanes 3 which discharge the water and air from pipe K and chamber f into the `discharge chamber b with the discharge Water from tail pipe C.
It will be understood that the invention is applicable to injector or jet condensers generally, including parallel flow condensers as well as counter-current condensers, and that various modifications may be made in carrying out the invention.
What I claim is l. The combination with a jet condenser and its condensing water supply and discharge pipe, of an ejector within the condenser for drawing off air and uncoudensed vapor, and an ejector discharge pipe separate from the condenser discharge.
Q. The combination with a jct condenser. and its condensing water supply and discharge pipe, of a liquid ejector' in the upper part of the condenser forV drawing off air and uncondenscd vapor, and a discharge pipe through which .the ejector delivers eX- tending downward through the condenser and clcsed to the condensing chamber.
3. The combination with a jet condenser, its condensing` water supply, discharge pipe and discharge pump, of a liquid ejector within the condenser for drawing off air and uncondensed vapor, and a discharge pipe carried by separate froni the condenser discharge pipe through which the ejector delivers to the` condenser discharge pipe throughwhich the ejector delivers to the condenser .discharge pump.
5. The combination with a jet condenser, its condensing water supply, discharge pipe and centrifugal discharge pump, of a liquid ejector within the condenser for drawing ofi' airI and uncondensed Vapor, a discharge pipe separate from and arranged within the condenser discharge pipe through which dthe' ejectorv delivers to the condenser discharge pump, and a centrifugal .pump` supplying water to said ejector.` j j 6. The combination with a jet condenser, ot' water ejector e, a Water supply for said ejector, ejector discharge pipe K, and centrifugal condenser discharge pump F having separate lnlets and impelling Vanes for the ldischarge from pipe K and the condenser.
7. -The combination with a jet4 condenser,
itsl condensing water supply, discharge pipe and discharge ump, .of a liquid ejector -within the con enser for drawing oii air and uncondensed vapor, and a discharge pipe separate from the condenser discharge pipe through which the ejector delivers.
8. The combination with a jet condenser and' itscondensing water supply and discharge means, of a liquid ejector within the j condenser for drawing off air and uncondensed vapor, and a pump and connections independent of said condensing water suppljT and discharge for supplying water to sa1d ejector.
