a (cl.
Thisinventlon relates to improvements in shell A and tube type heat exchangers and more particularly to an internal baiile construction therefor.
.been provided to more nearly obtain true countercurrent'flow of the two fluids and to increase the distance of flow oi. the external fluid between the inlet and the outlet; and numerous patents have been granted for various types of mechanical devices for assisting in sealing the joint between the edges of the baflle and thewall of the shell. Many of these devices, however are inefiicient and permit objectionable lay-passing of the external fluid from inlet to outlet, and all have proved to be complicated and expensive.
It is the principal object of our present invention to provide a simplified construction for assuring a leak-proof joint between a longitudinal baflle and the interior of the shell and tube heat exchanger, which construction is without mechanical complications and requires the minimum of shell modification.
More specifically, we provide simplified means of a detail of the securing mechanism as would appear from an enlargement of a section taken at the lefthand side of Fig. 1;
Fig. 4 is a cross-section 'taken'substantially along the line 4-4 of Fig. 3; and
Fig. 5 is an end view, with parts broken away,
taken substantially along the line 5-5 of Fig. 4
showing the arrangement of the pacl ring.
' In accordance with our invention, the heat exchanger shell in is generally a cylindrical member (although the construction will be equally as efiective with any other closed shape) containing atubebundle, generally indicated at l2, consisting of a plurality of tubes which at one end are suitably anchored in the fixed tube sheet l4 "and at the other end are fixed to the floating tube sheet 15. As is well understood in the art,
for drawing a 'gasket carried by a longitudinal Y baiile in a shell and tube heat exchanger to the shell wall, which means are operated from the exterior ofthe shellbulrin such a positive manner that tightness can be obtained to the desired degree; I I
Another object 'ofthe invention is to provide a removable longitudinal baflle fora shell and tube type heat exchanger'in which the body portion of the baflle extends substantially across the shelld body and is provided with movable marginal sealing gaskets in sealed relation with the baflle and movable into 'sealedrelatiomwith the shell wall by external positively actuated members.- Further objects and advantages of our inven- "tion will appear from the following disclosure ofa preferred form of embodiment thereof taken in connection withv the attached drawing illustrative thereof, in which;
, Fig. 1 is a substantially horlzontalcross-sec- 1 tion taken substantially along the line l-l of Fig. 2, with parts broken away, showing the internal construction of a heat exchanger provided with our improved balile;
Fig. 2 is a substantially vertical cross -section taken on the line 2 -2 of Fig. 1; r
' Fig. 3 is a plan'vlew, with parts brokenaway,
the fixed tube sheet I4 is generally secured between flanges IT on the shell and on the channel 18, and the floating tube sheet [6 is provided with the floating tube sheet cover l9 secured in any suitable or preferred manner thereto.
Although the openings to the channel l8 are not shown, it is to be understood that'a flow of liquid takes place through,the tubes in the tube bundle I2 and that heat is exchanged with such liquid by the passage of a second fluid across the outside surface of the tubes. This object is ac-- complished by circulation of the second -fluid through the inlet and outlet nozzles 2| and 22., It isthe purpose of the longitudinal baflle, gener-' ally indicated at 24, to provide the desired flow of the external fluid and at the same time to prevent; the by-pass of the external fluid between the nozzles 2| and 22 in the passage of such fluid from one end of the tube bundle to the other.
.The bafile 24 is thus to be understood to be a longitudinally extending battle which, for the purpose of our invention, is also removable in order that the tube bundle can be removedfrom the. shell for cleaning and for repair. It is not necessary, however, that the baflle 26 be located at the major diameter or greatest'widthof the shell; for, if desired, more than one baflle may be used in the same manner, and they may readily be spaced from the plane of the greatest width of the shell. In accordance with preferably comprises two face plates 25 and 28 which are constructed :of relatively thin gage sheet materialgand which are suitably spaced from each other by means of a central spacer bar v 2'! that is suitably welded or otherwise secured to the respective face plates as. at 2la.' 1The bafile 3 24 :is arranged to engage thgipside' of the-flxed our invention, the bafile 24 tube sheet 14 and is suitably cutaway at ms;
the opposite end to provide for the flow. oi the a external fluid.
Although the baflie 24 is normally the full width which can be permitted in the'shell, it is necessary to have adequate clearance for the removal the length or the shell on each edge of the baflie is so great as to allow enough by-passing of fluid between inlet and outlet as to substantially nullify the eifect of the baflle. A considerably higher.
heat exchange eflicie'ncy can be obtained if substantially all by-passing of .the fluid is prevented.
We prevent this by-pas'sing and effectively seal the baiiie to the shell by providing on each side of the baflle along the length thereof a sealing bar or yoke 28 which abuts against a channelshaped gasket-carrying element 29 as shown in Fig. 4. The yoke and channel extendbetween the respective plates25 and 26 of the baflle 24, and a packing 3o secured in the channel 29 as by any suitable means extends outwardly thereof. As hereinafter described, the packing 30 is forced against the inner wall of the shell III for the desired seal.
The yoke 28 is preferably drawn toward the wall "I, of the shell in accordance with our invention by means 01' suitable. studs 32 extending through suitable apertures in the shell wall. These studs e age in blocks 34 which'are suitablvwelded or otherwise secured as at 35 tofithe yoke 23. At the respective locationsoi the studs 32, the plates 25 and 26- are cut away so that the block 34 may beer a sufliciently large'size'to permit tapping for the studs 32. The packing 30 extends up over the block 34, however, and nearly reaches the shank of the studs 32 so that there is little or no possible space through which the external fluid can by-p'ass.
Inasmuch as a similar yoke is provided oneach of the respective sides or the baiiie 24, by
appropriate spacing of the studs 32, it is'p'osslble to apply an effective pressure on each of .the channels 29 carrying the packing 30 to mom-- pllsh the desired seal. The yoke may be slightly tri n ular in shape to afford a good beam structure. 1
Both yoke 23 and channel member 23 are made relatively tightly fitting with respect to face plates 25 and 26. In this manner a substantially leak-proof construction is provided, and the channel member 23 is brought into substantially leak-proof relationwith respect to the longitu .dinal edge or the baiiie as pressure is applied to the yoke 28 through studs 32. At the same time are provided with the usual caps or plates so that, after adjustment or the baiile is made, the nozzles can be hermetically closed to avoid any leaks.
'It will be understood that the studs32 are inserted to the desired point in the heat exchanger shell; and then, by screwing-down. on the studs, the yoke is drawn outward until the seal has been completed.
With such a construction there are no parts that can he objectionably disturbed by changes temperature within the shell, and there are no complicated mechanisms to become out of order; and effective sealing is readily accom-- plished and permanently retained. ;The baflle the studs, and then the from the shell. a v
