Technical Field
The utility model belongs to the technical field of pressure vessel heat transfer portion connection structure technique and specifically relates to a shell side and tube side barrel and support shell's connection structure.
Background
The heat exchanger of the pressure vessel comprises a shell side and a tube side. The shell side refers to the distance of fluid flowing along the gaps among the shell, the tube bundle and the baffle plates of the heat exchanger, the tube side refers to the distance of fluid flowing along the tube bundle of the heat exchanger, and the shell side cylinder and the tube side cylinder are spaces where the fluid flows through the shell side and the tube side respectively. The shell side and the tube side of the heat exchanger need to be welded in a sealing mode and can bear certain pressure, so that the connecting structure has high requirements.
As shown in fig. 1, the existing connection structures of the shell-side cylinder and the tube-side cylinder and the support shell are all flat fillet welds, that is, a flat plate is arranged between the outer wall of the shell-side cylinder and the outer wall of the tube-side cylinder, and the flat plate can also play a role in sealing the shell-side cylinder. When the pressure requirement constantly improves, dull and stereotyped thickness can increase by a wide margin, causes a large amount of losses to the material, not only connects inconveniently, and intensity also is difficult to guarantee moreover.
In addition, as shown in fig. 2, a circle of supporting shell needs to be welded inside the tube pass cylinder, the original connection mode is similar to the connection mode of the shell pass cylinder and the tube pass cylinder, a flat plate is used for connection and is reinforced by fillet welding, and the problem of high material consumption and low strength is also faced.
SUMMERY OF THE UTILITY MODEL
The applicant provides a connecting structure of a shell pass and a tube pass cylinder body and a support shell aiming at the defects in the prior art, and an arc-shaped girth welding structure is used for replacing flat fillet welding, so that the material consumption is reduced, the production cost is reduced, and meanwhile, the welding strength is improved.
The utility model discloses the technical scheme who adopts as follows:
the utility model provides a connection structure of shell side and tube side barrel and support shell, includes shell side barrel and tube side barrel, supports the shell and sets up in the tube side barrel, the bottom sharing tube sheet of the top of shell side barrel and tube side barrel, the shell side barrel upwards extends along tube side barrel periphery and forms the toroidal cavity of parcel tube side barrel, the toroidal cavity top is the arcuation structure, still sets up the annular weld who is used for encircleing tube side barrel outer wall in the top of arcuation structure, support shell and annular member body coupling and weld in the inner wall of tube side barrel.
The further technical scheme is as follows:
the surface of the annular welding line is an inclined plane, and the inclined plane inclines towards the other end of the annular welding line connected with the tube pass cylinder along one end of the annular welding line connected with the outer wall of the shell pass cylinder;
one end of the ring-shaped piece is connected with the inner wall of the tube pass cylinder body, and the other end of the ring-shaped piece is connected with the top end of the supporting shell.
The utility model has the advantages as follows:
the utility model discloses a change the connected mode of shell side and tube side barrel and support shell to the dull and stereotyped fillet weld of boxing replacement has saved the welding consumptive material, and reduction in production cost has also improved connection structure's intensity simultaneously.

Fig. 2 is a schematic view of a connection manner of a conventional tube-side cylinder and a support shell (only the connection of the tube-side cylinder and the support shell is illustrated).
FIG. 3 is a schematic diagram of the upper section of the heat exchanging part of the oxidizer.
Wherein: 1. the upper section of the heat exchange part of the oxidizer; 101. a shell-side cylinder; 102. an annular cavity; 103. an arc-shaped structure; 104. an annular member; 105. a support housing; 106. a tube pass cylinder; 107. a bevel; 108. an annular weld; 109. a tube sheet.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 3, the utility model discloses a shell side barrel 101 and the tube side barrel 106 that are located oxidizer heat transfer portion upper segment 1, it sets up in tube side barrel 106 to support shell 105, the bottom common tube sheet 109 of the top of shell side barrel 101 and tube side barrel 106, shell side barrel 101 upwards extends the toroidal cavity 102 that forms parcel tube side barrel 106 along tube side barrel 106 periphery, toroidal cavity 102 top is ARC structure 103, still set up the annular weld 108 that is used for encircleing tube side barrel 106 outer wall in ARC structure 103's top, support shell 105 and ring member 104 body coupling and weld in the inner wall of tube side barrel 106. The surface of the annular welding line 108 is an inclined plane 107, the inclined plane 107 inclines towards the other end of the annular welding line 108 connected with the tube pass cylinder 106 along one end of the annular welding line 108 connected with the outer wall of the shell pass cylinder 101, one end of the ring-shaped element 104 is connected with the inner wall of the tube pass cylinder 106, and the other end of the ring-shaped element 104 is connected with the top end of the support shell 105.
The utility model discloses need not use the flat board, when welding shell side barrel 101 and tube side barrel 106, welding material upwards fills in the clearance of shell side barrel 101 and tube side barrel 106 gradually from the outer wall of shell side barrel 101 in, forms smooth transition's inclined plane 107 to the direction shrink of tube side barrel 106 outer wall simultaneously. When the tube side cylinder 106 and the support shell 105 are welded, the strength requirement is lower than that of the connection structure of the shell side cylinder 101 and the tube side cylinder 106, so that the clad connection is not needed, only the two ends of the ring piece 104 are required to be firmly welded to the inner wall of the tube side cylinder 106 and the upper end of the support shell 105 respectively, and the connection surface of the support shell 105 and the ring piece 104 is ensured to be vertical to the horizontal plane after the welding is completed.
The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made within the scope of the invention.
