Abstract
The utility model discloses a connecting structure between a heat exchange tube head and tube plates in a waste heat boiler which is good in sealing performance and not prone to leak. The connecting structure comprises a heat exchange tube head, an inner tube plate and an outer tube plate; the heat exchange tube head penetrates through the inner tube plate and the outer tube plate, and then the end portion of the head exchange tube head is welded with the outer tube plate; the periphery of the inner tube pipe stretches to the outer tube plate and is attached to the outer tube plate, a discharging cavity is formed between the inner tube plate and the outer tube plate, a discharging hole for communicating the outside with the discharging cavity between the inner tube plate and the outer tube plate is arranged on the inner tube plate, and the heat exchange tube head is welded with the inner tube plate. The connecting structure between the heat exchange tube head and tube plates in the waste heat boiler has the advantages that welding connections among the heat exchange tube head, the inner tube plate and the outer tube plate are utilized, tightness among the three is improved, and normal operation of the waste heat boiler is guaranteed.
Description
Technical field
The utility model relates to the syndeton between the heat exchanger tube tube head and tube sheet in a kind of waste heat boiler.
Background technology
As shown in Figure 1; Syndeton in the waste heat boiler that present chemical equipment industry is adopted between heat exchanger tube tube head and the tube sheet; Comprise internal tube plate 1, outer tube plate 2 and heat exchanger tube tube head 3; Heat exchanger tube tube head 3 passes internal tube plate 1 and outer tube plate 2 its ends, back and outer tube plate 2 welding; Be provided with Hough pipe nipple 6 between internal tube plate 1 and the outer tube plate 2, form atria 4 between internal tube plate 1, outer tube plate 2 and the Hough pipe nipple 6, internal tube plate 1 is provided with the porus excretorius 5 that is communicated with atria 4 between the external world and internal tube plate 1, the outer tube plate 2.Expanded joint between heat exchanger tube tube head 3 and the internal tube plate 1.As occurring leaking (great majority are bond opens) between heat exchanger tube tube head 3 and the outer tube plate 2; Because heat exchanger tube tube head 3 is when passing outer tube plate 2; Between heat exchanger tube tube head 3 and the outer tube plate 2 gapped (technological requirement), the medium of leakage can get into atria 4 through this gap, discharges from porus excretorius 5 then; As can guarantee the isolation fully of two kinds of heat transferring mediums.Owing to adopted Hough pipe nipple 6 between internal tube plate 1 and the outer tube plate 2, caused between internal tube plate 1 and the outer tube plate 2 apart from becoming big.It is long that heat exchanger tube tube head 3 stretches out the length of internal tube plate 1, and can't adopt the mode that is welded to connect between the internal tube plate 1, and can only adopt expanded joint to connect.Because internal tube plate 1 is excessive with heat exchanger tube tube head 3 ends distance, can only adopt deep hole hydraulic pressure to expand (the leakage probability of this method is higher than welding), and the sealing property less reliable of expanded joint is easy to generate the seepage phenomenon, thereby causes equipment fault.
The utility model content
The utility model technical problem to be solved is: the syndeton in the waste heat boiler that a kind of good seal performance is provided, is not easy to leak between heat exchanger tube tube head and the tube sheet.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: the syndeton in a kind of waste heat boiler between heat exchanger tube tube head and the tube sheet; Comprise heat exchanger tube tube head, internal tube plate and outer tube plate; The heat exchanger tube tube head passes its end and outer tube plate welding behind internal tube plate and the outer tube plate, extends and fits with outer tube plate to outer tube plate around the said internal tube plate, forms atria between internal tube plate and the outer tube plate; Internal tube plate is provided with the porus excretorius that is communicated with atria between the external world and internal tube plate, the outer tube plate, and the heat exchanger tube tube head is also with the internal tube plate welding.
The beneficial effect of the utility model is: all adopt between heat exchanger tube tube head and internal tube plate, the outer tube plate to be welded to connect, improved the sealing between the three, guaranteed the operate as normal of waste heat boiler.
Description of drawings
Fig. 1 is the structural representation of the syndeton between heat exchanger tube tube head and the tube sheet in the waste heat boiler in the background technology;
Fig. 2 is the structural representation of the syndeton between heat exchanger tube tube head and the tube sheet in the utility model waste heat boiler.
Among the figure: 1, internal tube plate, 2, outer tube plate, 3, the heat exchanger tube tube head, 4, atria, 5, porus excretorius, 6, the Hough pipe nipple.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
As shown in Figure 2; Syndeton in the described a kind of waste heat boiler of the utility model between heat exchanger tube tube head and the tube sheet; Comprise heat exchanger tube tube head 3, internal tube plate 1 and outer tube plate 2; Heat exchanger tube tube head 3 passes internal tube plate 1 and outer tube plate 2 its ends, back and outer tube plate 2 welding, fits to outer tube plate 2 extensions and with outer tube plate 2 around the internal tube plate 1, forms atria 4 between internal tube plate 1 and the outer tube plate 2; Internal tube plate 1 is provided with the porus excretorius 5 that is communicated with atria 4 between the external world and internal tube plate 1, the outer tube plate 2, and heat exchanger tube tube head 3 is also with internal tube plate 1 welding.The quantity of heat exchanger tube tube head 3 can require to set according to actual production.After adopting said structure between heat exchanger tube tube head 3 and the internal tube plate 1; Because after all the employing mode of welding is connected between heat exchanger tube tube head 3 and the internal tube plate 1 and between heat exchanger tube tube head 3 and the outer tube plate 2; Guarantee the sealing of atria 4, reduced the maintenance of equipment, improved production efficiency.Even between heat exchanger tube tube head 3 and the internal tube plate 1 or the bond open between heat exchanger tube tube head 3 and the outer tube plate 2; Promptly leak; Medium after the leakage all can get into atria 4 through gap between heat exchanger tube tube head 3 and the internal tube plate 1 or the gap between heat exchanger tube tube head 3 and the outer tube plate 2; Discharge the operate as normal of the medium influence equipment of avoiding leaking at last from porus excretorius 5.
Claims (1)
1. the syndeton between heat exchanger tube tube head and the tube sheet in the waste heat boiler; Comprise heat exchanger tube tube head, internal tube plate and outer tube plate; The heat exchanger tube tube head passes its end and outer tube plate welding behind internal tube plate and the outer tube plate, it is characterized in that: extend and fit with outer tube plate to outer tube plate around the said internal tube plate, form atria between internal tube plate and the outer tube plate; Internal tube plate is provided with the porus excretorius that is communicated with atria between the external world and internal tube plate, the outer tube plate, and the heat exchanger tube tube head is also with the internal tube plate welding.
