z claim. (ci. 257-223) My invention relates to the art of heat exchange and has as its principal object the provision of an arrangement requiring a minimum ground space but having high heat eiiiciency and being convenient to a high degree.

It is a common practice in the petroleum re-A lining trade to discharge the highly heated iluid from a tube type heating coil into a talllseparating and/or vaporizing chamber and to conduct the vapors from such chamber to a heat exchanger in which the heat of the vapors is transmitted to a considerable extent ing toward the heating coil. In apparatus within my invention, the separating and/or vaporizing lchamber may be combined with the heat exchange elements in such manner that only one foundation is required and no additional ground space need be used over that above the separating chamber itself. Also, the heat exchange elego ments may be readily inspected and ,cleaned when required.

Inlorder that my invention, together with its objects and advantages may be readily and fully understood, I will now describe by way of example and in connection with the accompanying drawings ai combined separating and/or vaporizing chamber and heat exchanger in accordance with my invention and selected from a number of possible embodimentsA thereof. In the drawings,

Fig. 1 is anelevation, parts being broken away,

of an apparatus within my invention.

Fig. 2 is a plan View oi' a header ring appearing in Fig. 1. 3

through thegcen- Fig. 3 isa transverse section f ter of the ring shown in Fig. 2.

In the installation illustrated in Iiig.'y l, the separating and vaporizing chamber i0- has inlet i2 in its lower end which connects with the discharge of a heating or cracking still of the coil or other type. Mingled vapors and/or liquids of high temperature enter the chamber III from the coil. Within chamber I 6 the pressure is somewhat reduced and the vapors rise to the top of the chamber while the, liquids are taken oi! through outlet I4 and/or through the bottom drain i6. -A

In the arrangement illustrated, the envelope of. the chamber I 0 is extended upward in the form of a ring lila and a casing Ib within -which are mounted a plurality of serpentine tubular liquid conducting I 6, I6, such' units being supported from the said ring. Preferably,

' there are two detachable Joints inthe envelope of. chamber Il, oneioint 2l being at the lower to raw oil mov-v edge of ring Ita and the other joint 22 between ring I 0a and casing Nb.

Ring Ilia is shown as an integral casting within which are two integral manifold chambers 24 and 26 each oi.' which is closed at one end while 5 the other end extends to the outside 0f the ring where it can.be connected to an inlet or outlet pipe by a ilange o'r other type coupling 2,6. The top walls of chambers. and 26 are drilled and countersunk to provide passages 36, 3|! and seats 10 32, 22 whereby the ends of the umts I8 may be coupled by readily breakable joints to the walls of the chambers 24 and 26 in position to receive fluid from or discharge fluid to such chambers. Each unit I6 is formed of a zigzag tube and all 15 the units together form a bundle through which a cooling fluid ows.

Vapors from the lower part and main part of chamber Il passup around the units I6 to heat the liquid therein. For this purpose I have made 20 -ring Ia with a wide aperture therethrough between manifold chambers 24 and 26. However, any form of vapor connection between the lower portions of chambers l0 and the portion-within casing l0b`may'be employed within my inven' 25 tion. In the arrangement illustrated, a horizontal baille 34 is placed below a portion-of the opening. 33 through ring lila and the gases pass up through the other half of such opening into the tube bundle formed of units I6. A vertical 30 baffle 26 extends from the bottom o f the tube bundle part way up the middle of such bundle so that the vapors pass around the upper edge of baille 36 and then downwardly'through the other half ofthel tube bundle and out through open- 35 ing 38 in the ring Ila. However, I do not limit myself to any particular form of path for the vapors through the space occupied by the units I6 and one may use a single or a multiple path arrangement within my invention as desired. 40 condensate formed within the casing Ilib at the left of the central baiiie 36 drains back through4 the opening in the ring Illa into chamber III. Such condensate as is formed within the casing Ilb at the right of central baille 36 may vbe 45 trapped back into the chamber III by suitable means not shown, but preferablyis` permitted to flow out with the gases through the outlet 28 so that it can be trapped out of the line connected to such outlet at any convenient place.

It will be understood that chamber I0 may in practice often be eighty `or so feet high and I have shown means at the top of such chamber for liftingthe casing Illb clear of the units Il to permit inspection and cleaning of the units. Such means comprises a framework II fixed to the upper por- `tion of ing Nb. On the framework Il is a trolley-device l so that, when joint 21 has been broken, the casing Illb can be hoisted by tackle means (not shown) and attached to trolley 4l and held out of the way above the units .I I. By such arrangement the ground space of a plant in which my invention may be use is economized to the maximum degree. However, I do not limit myself to this in all cases. Y

It will be understood further that I do not limit myself in all cases to details of the foregoing description, but wish the following claims to be construed as broadly as their terms of the art permits.

1. The combination in bose ring having a wide side opening, a casing on said ring, a tube bundle supported from said ring and extending into said casing, connections whereby one fluid may pass through said bundle and baiilinl means whereby another fluid passing through tureinsaidringmaypassover out through said side ope 2. The combination as set forth in claim l and in which the ring has header chambers therein on opposite' sides of its central opening.
