Patented Feb. 7,, 1950 TUBE BUNDLE dSSEIVmLiZ FOR HEM? IEXMHIIANGERS AND THE JLMIE tion oi New Yoi'h Application February 16, 1944, Serial No. 522,603
3 Elaims.
This invention relates generally to heat exchangers but more particularly to certain new and useful improvements in the tube-supporting frame or tube bundle assembly for such exchangers.
It has for one of its objects to provide a tube assembly frame of this character which is so designed and constructed as to permit the ready assemblage of its parts and its handling, interchanging and installation in the shell of the heat exchanger, and which is adjustable and provides for the thermal expansion and contraction of its parts when the exchanger is in operation.
Another object of the invention is to provide a removable and adjustable tube nest assembly frame which has been primarily designed for use in connection with carbon or other non-metallic tubes and tube sheets and wherein maximum protection is aflorded such parts against breakage during interchanging, handling and shipment.
Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.
In the accompanying drawings:
Figure 1 is a. longitudinal section of a heat exchanger in which my improved tube bundle assembly frame is installed. Figure 2 is a cross section taken on line 2--2, Figure 1. Figure 3 is an enlarged sectional detail view showing the adjustable tie rod construction.
Similar characters of reference indicate corresponding parts throughout the several views.
Referring now to the drawings, In indicates the shell or cylinder of a. heat exchanger which is provided at one end with an annular attaching flange H and at its opposite end with a similar flange l2. Adjacent its ends the shell has a fluid inlet I3 and an outlet II. The improved tube nest or bundle assembly frame which is adapted to be removably and adjustably arranged within the shell is preferably constructed as follows:
The numerals I5, I 6 indicate tube head retaining or supporting rings or members which are applied to the opposite ends of the shell I0, the ring i being adapted to be rigidly connected to the shell-flange H by bolts l1, while the retaining ring it has a slide or floating fit with the corresponding end of the shell and a stufllng box it is provided including a gland ring l9 secured to the shell-flange M by bolts 20. Disposed between and connecting these supporting rings and in protective relation about the tube bundle are longitudinal tie rods M which are secured by w screw connections 22 or the like at one end with the ring it while their opposite ends terminate in adjustable rod-sections it removably seated at their outer or free ends in companion seats or sockets it formed in the inner face of such ring it. The opposing ends of each tie rod and its adjustable rod section are threaded and in coupling engagement therewith is an internallythreaded sleeve or nut 25 abutting at its outer end against a shoulder 2% formed on the rodsection 2%. A locking nut 21 applied to the tie rod and engaging the inner end of the adjustable sleeve serves to retain the rod-sections in their adjusted position. By this construction, the assembly frame can be readily adjusted to allow for thermal expansion and contraction of its parts and the separation of the frame at this point, when required, is facilitated for replacement of parts.
Mounted on the tie rods 2| in suitably spaced relation lengthwise thereof are a plurality of batfles 28 in the form of disks which are: provided with alternate openings 29. Spacing sleeves 30 are applied to the rods between the battles to retain them in their proper spaced relation and against endwise relative displacement. The outermost baflle at that end of the assembly frame adjoining the adjustable tie rod sections is held against outward displacement by retaining nuts 3| applied to the threaded portions of the tie rods 2|.
This frame structure has been more particularly designed for use as a protective assembly for carbon or other non-metallic tubes and tube sheets, but is not limited to such use, and in the drawings the tubes are indicated at 32, the tube heads or sheets at 33 and 34, and the head covers at 35 and 36, respectively. The tubes are cemented or otherwise secured at their ends to the tube sheets, the tube sheet 33 being seated in an annular groove 31 in the fixed retaining ring I! and together with its head cover 35 is securely fastened to such ring by a steel head plate 38 and tie bolts 39. The companion tube head or sheet 34 is seated in an annular groove 40 in the sliding or floating retaining ring is and together with its head cover 38 is securely fastened to such ring by a steel head plate 4i and tie bolts 42. In the drawings, the fixed head cover is shown having inlet and outlet nozzles at 43, ll connected thereto and enabling the fluid undergoing treatment to have a multl-pass circulation through the heater, although it is understood that such nozzles may be applied to both head covers.
While manifestly simple, compact and rugged in construction, this tube nest or bundle assembly frame afiords maximum protection to the tubes during handling and shipment, and can be readily assembled in a minimum period of time. Furthermore, the device is so designed that it can be readily adjusted, as desired, to permit the expansion and contraction of the parts in response to varying thermal conditions existing in the heat exchanger. The sectional and adjustable tie rod construction also facilitates the separation of the floating retainer ring l6 from the floating tube head 34 for renewing the gasket between these parts. The whole tube nest or bundle assembly frame also permits quick easy and safe removal or separation of the tube bundle from the heat exchanger shell in for repairing or replacing any of its parts or interchanging it with another bundle of the same size.
In assembling the tubes 32 and in turn the protective frame about the same, prior to installation in the shell M, the tubes are first secured at one end to the tube sheet 33, after which the retaining ring l5 together with the tie rods 2!, baffles 23 and spacing sleeves 3B are properly positioned in the manner shown in Figure 1, with the outermost bafile held against displacement by the nuts 3|. The rod-sections 23 and their adjusting sleeves 25 are then connected to the tie rods, the floating tube sheet retaining ring as is then brought into socket-registering relation with the ends of such rod-sections, and finally the tube sheet 34 is secured in place on the adjoining ends of the tubes 32, suitable packing being provided between the tube sheets 33, 34 and the opposing grooved faces of the companion rings l5, 19. This tie rod and baiile arrangement together with the fixed and floating tube sheet retaining rings form a complete protective cage or enclosure and effective mechanical support for the carbon tubes 32, and in the handling of this tube bundle assembly for insertion or removal from the heat exchanger shell the weight and strain is placed on the steel parts, such as the rings, tie rods, baflies, etc., thereby effectually eliminating any danger of breakage of the tubes, as well as the tube sheets.
The installation of the tube bundle assembly into the shell Ill of the heat exchanger, after making the proper adjustment of the sectional tie rods 2 I, 23 to the predetermined length desired to take care of the difference in thermal expansion in a given installation, is accomplished by inserting the assembly into the shell, bolting the fixed ring i5 thereof to the shell-flange I l and mounting the gland ring I9 in sealing relation to the floating ring l6 and bolting it to the shell-flange l2. Thereafter, the head covers 35, 36 and head plates 38, 4| are mounted in place and securely held by the tie bolts 39, 42 to the respective retaining rings l5, IS. The removal of the tube bundle assembly from the shell is accomplished by the reversal of the steps for installation and in this connection, while the head cover 36 and its head plate 4| are detached from the retaining ring l6, it is not necessary to detach the head cover 35 and its head plate 38 from the companion retaining ring l5. It should be pointed 4 out here that this assembly affords a freedom and flexibility of bafile arrangement depending on the purpose to which the exchanger is to be used.
