Patented March 12, 1907.
To all Awhom it may concern:
Be it known that I, ERNST KOERTING, a subject of the Emperor of Germany, and a resident of Pegli, Italy, haveinvented cer- ,tainA new and useful Improvements in Jetv Qondensera of which' the following, taken in .conjunction with .the accompanying drawing., is a full and truespecification.
ity is increased and the discharge ofthe con-4 The invention herein described relates to jet'jeondensera and consists 1n certain 1mprovements upon l previous constructions whereby the vacuu-m fand the cooling capacdensed or cooled ma'terialsfacilitated, as will be presently described in detail and. 'more particularly pointed out in the claims.
Referring to the drawing, Figure 1 is a central axial section through a jet-'condenser embodying-one form of my invention. Figs.
' 2 and 3 are res ectiyely transverse sections of y the condenslng-tube on lines IIA II and III III, respectively, of Fig. 1 and'in the direction of the arrows. side elevation of the nozzle oi' a modied-form ofcondenser. Fig. 5 is a Vtransverse section of said nozzle on line V V on Fig. 6, and Fig. 6 is an axial section through the nozzle and condensing-tubes of said modifiedform.
The device comprises a main steam-casing from which the steam or. other gas is to be exhausted, and contained within this casing is'a condensing-tube c, which is perforated by a multiplicity of steam-passages d, inclined toward` the discharge opening, as shown in the'drawing'. At its upper end the said tube is held betweenflugs a on the casing and in line with an opening in the up er end thereof, at which oint there'is provi ed a'water-nozzle a, an at its lower end the tube is 4provided with a tail-tube c', passing through a lower opening in the casing, from which the condensed steam and gases may b e discharged to atmosphere. The nozzle al 1s -formed as a chamber located in the opening of the casing at the end of the tube and is adapted to be connected with a water-supply in any suitable manner. The partition between the chamber-and the tube is provided with-a number of small j et-holes b, which are so arranged that the water-jets emitted therefrom are directed along the wall of the condensing-tube, past the openings d thereof, and converge at or near the junetlon of appended .for the steam, and in addition to this increased cooling effect' the permanent gases Fig. 4 is a detail in` water-nozzle; as shown, for guiding the jets.
The said jet-holes b are preferably arranged inone or more circles concentric with the axis of. the tube, so that the waterfjets -occupy the surface .of an imaginary cone', which has its axis coincident with that of the tube. The condensing-tube also is tapered so that' its erforated wall is substantially .parallel Wit the convergent jets. L
In operation the convergent jets create a partial or'comparative vacuum Within the condensing-tube, andthe steam entering the tube through the inclined passages d encounters the water and is thereby cooled and carried outthrou h the tail-tube.. By virtue of the multipicity of jets a maximum water area is provided as a cooling-surface 'always contained in the steam are attracted into the space inside the bundle of jets, where theyv become imprisoned in the Water at the point of im ingement and are from thence carried off wlth .the water in a manner which I find to be superior to the previous method. of allowing them to pass between a single solid jet and the Wall o the tube. At the same time a greater vacuum is secured..
In,the form of condenser shown in Fi s'.
steam directly into the space inside the bundle of jets, which means may be employed either with or without the condensing-tube c, and comprehends in the present case a series of lateral steam-passages d in 'the nozzle interlocated between the jetholes b therein and opening centrally of them.
`For .the purpose of conducting the steam 95 from these passages into intimate contact with the'water a tapered chamber or tube e is formed onA the nozzle, which has inclined steamassagesf, like those of the tube c, and
takes t e place of the central guide of Fig. ,1. roo
The convergent water-jets pass alongside of the wall of this tube and draw the steam out of it in the same manner'as in the casefof the tube c. When this tube is employed in conjunction with the tube c, its effect is obviously 1o 5 supplemental thereto. In the case of either tube ltheinclined steam-passages are interlocated between the water-jets, so that the steam issuing from said passages does not impinge directly upon said jets or distort 11o vzo them. This relation Will be observed in Fig. 2, which shows the steampassages d alternated in position With the jet-holesb.
While the tail-tube is shown 4herein as an 5 lntegral part of the condensing-tube it will*` dunderstood that this form of construction,`
'i 5 Waternozzle`-adapted teemit a number .ot convergent Water-jets past' the` openings of 'said perforations."
