. for reissue filed March 11,
The present invention relates broadly to heat exchange, and more particularly to a heat exchanging means in the form of a tubular condenser of the surface type having a conduit leading from the vapor space at the inlet end of the condenser to a chamber below the tube nests for maintaining-a high condensate temperature, as claimed, for exam ple, in my copending application Serial No.
587,196, filed September 9, 1922, although the n specific construction of'the condenser is immaterial, I
This invention has to do particularly with the removal of non-condensable gases, such It'has heretofore been proposed to eflect the removal ofthe air by means of a separate air connection on each side of the condenser. In many cases,
. however, it is desirable to use only one air pumping means, and where such single means must withdraw from both of the air connections an elaborate and expensive pipe layout is required to reach both sides of the condenser. As condensersare frequently as large as twenty feet in diameter, the expense and complication involved in .such an arrange ment become apparent. Furthermore, if the air pumping means is located at a high level I i with respect to the condenser, operating problems are encountered.
It is not feasible to bring the connectionsunderneath the condenser and thento the pumping means, as the piping willform a trap for the collection 'thereby interfering with efficient airremoval. On the other hand, it is often diflicult to bring air pipes over the top of the condenser to obviate this-trapping action, in-
I asmuch as the foundations of the turbine exhaust seriously interfere with such an arrangement.
Also, it has been proposed to withdraw air I ,through a single conduit extending downwardly through substantially centrally thereof. When the air the bottom of the condenser pumping means has been located at a high level, this construction also forms a water collecting trap interfering with the with drawal of the air.
. By the present invention, there is provided an efiicient construction for removing the non 613,367, filed January 18, 1923. Application 1927. Serial No. 174,670.
condensable gases-without the necessity'of employing an expensive piping layout. Also, the objection to water trapping'is eifectively overcome.
In the accompanying drawings, there is illustrated, more or less 7 I embodiment of the present invention, it being understood that the drawings do not define the limits of the invention, andthat changes may be made in the construction and operation disclosed therein without departing from the spirit or scope of my broader claims.
In the drawings v Figure 1 is a vertical sectional view through a condenser constructed in accordance with the present invention; and
Figure 2 is a perspective view, partly brokon away, illustrating a portion of the withdrawing means tor the non-condensah1e gases.
In carrying out the present invention, there may be provided a condenser shell 2 of any usual or well known construction having a vapor receiving opening 3 at its upper end. Formed within the shell Zare a plurality of banks ornests of tubes 4 between which the vapor passes ,during itstravel through the condenser.
Extending from'the vapor space above the tubes 4 and adapted to conduct vapor from such space to a point adjacent the terminus of flow through the condenser, is a conduit 5 in the illustrated-embodiment of the invention, this conduit is formed by spaced plates 6 extending longitudinally of the condenser and located between the tubes. lhe exact construction and location of'theconduit is, however, imm ateriaL. 7
There is preferably formed adjacent-the terminus of flow through the condenser proper, a zone or chamber 7- which is separated from the interior of the condenser proper by aperforated plate 8. The openings in the plate 8 are of such size condensate from the condenser is permitted to readily pass therethrough, and the noncondensable gases fromthe chamber are perand number that the t5 diagrammatically one i mitted to pass upwardly into the condenser wardly densable gases liberated willbe ese non-condensable rected through openin the interior of a cham er 11 formed in any desired manner, or by a suitable casting, and secured in position between the plates 6. It apparent that any desired number of chambers 11 ma be provided and spaced at suitable 'interva s throughout the length of the conduit 5. From these chambers the non- I condenser the tion 13 leadin l'withdrawing means. Irrespective of whether Y this withd condensable gases pass through suitable o into'conduits 12 extending laterally fifths banks of tubes to one side of the on the side of the condenser. From this point effectively withgases may be h a suitable g to an ejector, pump or other drawn throu rawing means is located at a higher or lower point than the condenser there is not provided any plping in which trapping of therein,
' I condensa le gases toa lpiint adjacent the water may occur. The advantages of the invention arise from e provision of a condenser in which it is possible to withdraw the non-condensable gases without the provision of an ex ensive pipin layout and without the culties ca by, the trapping of water.
I claim:
1. In a condenser, a shell having a tube nest a conduit for conducting fluid to a zone below said tube nest,'and means at least partly supported by said conduit for conductnon-condensable gases to a point on the u a tube Bi e of the condenser shell.
2. In a condenser, a shell having nest therein, a conduit for conducting fluid to -a point adjacent the flow'terminus through the tube ported b said nest, and means at least partly supconduit for conducting nona point on one side of the condenser shell. 7
3. In a condenser, a shell having a tube nest therein, a conduit for conducting fluid to apomt adjacent the flow terminus of the tube nest, and means extending from said conduit 1 to said shell" for conducting non-condensable $8118 to'a point e on one side of the condenser having a tube nest Ina'condenser,ashell conducting vapor to therein, a conduit for nest, and means exte ding one side of the condenser shell for withdrawing all of the non-condensable gases.
5. In a condenser, a shell having a tube nest therein, aconduit for conducting vapor to a point adjacent the mg to a point ejecting connec-.
flow terminus of the to a point on flow terminus of the tube nest, and means within the shell and extendon one side of the shell for withdrawing non-condensable gases from the condenser.
6. In a condenser, a shell .having a plurality of banks of tubes therein, a conduit for conducting vapor to a point adjacent the terminus of flow through said banksof tubes, and means extending between certain of said banks of tubes for conducting non-condensable gases from within the condenser to a point on one side thereof. In a condenser, a shell having a tube nest therein, a conduit for conducting vapors to a point adjacent the terminus of flow through said tube nest, means Within said conduit for receiving non-con'densable gases from the condenser, and means for conducting said 'ases from said means to a point on one si e of the condenser.
8; In a surface condenser, a shell having a plurality of tube nests therein, a heating chamber within the shell below the tube nests, means extending between passing steam independently thereof. into the heating chamber, means for permitting the escape of gases from the heating chamber to the tube nests, and means for conducting such gases to a point on one side of the condenser shell.
In testimony whereof I have hereunto set my hand.
