[0026] Next, in combination with the implementation manners of the present utility model, the technical solutions in the implementation manners of the present utility model will be clearly and completely described.

[0027] Such as Figure 1 And Figure 2As shown in the figure, a heat exchange heat storage device includes a steam accumulator 1, a medium accumulator 2, and a number of steam generating tubes 3. The steam accumulator 1 is surrounded by a feed inlet 11, and the medium accumulator 2 is surrounded by a discharge outlet 21. One end of the steam generating tube 3 is connected to the steam accumulator 1 and surrounds the feed inlet 11. The other end of the steam generating tube 3 is connected to the medium accumulator 2 and surrounds the discharge outlet 21. It further includes a feed baffle 5. The feed baffle 5 is arranged around the feed inlet 11 and is fixedly arranged on the steam accumulator 1. At least one expansion joint 51 is arranged on the feed baffle 5. A medium that can absorb and release heat is filled in the medium accumulator 2. In this embodiment, the medium filled in the medium accumulator 2 is water. High-temperature substances enter the interior of the heat exchange heat storage device from the feed inlet 11. The high-temperature substances heat the medium in the steam generating tube 3. The heated medium gradually vaporizes to form steam. The steam moves upward into the steam accumulator 1, converting the energy from fossil energy or solid materials into the energy stored in the medium, realizing the energy exchange, and storing it in the medium for further utilization. When fossil energy or solid materials enter the feed inlet 11, in order to improve the seal of the feed inlet 11, the feed baffle 5 is designed. However, the feed baffle 5 is fixedly arranged on the steam accumulator 1. When high-temperature materials enter from the feed inlet 11, the feed baffle 5 and the steam accumulator 1 heat up and expand simultaneously. There is cooling of the steam-water mixture in the steam accumulator 1. Therefore, the temperature difference between the feed baffle 5 and the steam accumulator 1 is relatively large. As a result, the expansion amounts of the feed baffle 5 and the steam accumulator 1 are quite different, leading to weld cracking. By arranging at least one expansion joint 51 on the feed baffle 5, the weld cracking caused by different expansion amounts is offset by the expansion joint 51, increasing the overall service life.
[0028] A guard plate 4 is arranged between adjacent steam generating tubes 3. The main functions of the guard plate 4 are: first, to enhance heat exchange; second, to enhance the overall structural strength; third, to seal the solid heat exchanger, preventing high-temperature materials from contacting the air and causing ablation or explosion due to the volatile components remaining in the materials.
[0029] This embodiment takes two expansion joints 51 as an example. As Figure 3 and Figure 4 shown, one of the expansion joints 51 is arranged on one side of the feed inlet 11, and the other expansion joint 51 is arranged on the other side of the feed inlet 11. Figure 4 Among them, one of the expansion joints 51 is arranged on one side of the feed inlet 11, and the other expansion joint 51 is arranged on the other side of the feed inlet 11. Figure 3 Among them, the two expansion joints 51 are symmetrically arranged with respect to the feed inlet 11. At this time, the two expansion joints 51 are symmetrically arranged, and the feed baffle 5 is more evenly stressed when heated and expanded.
[0030] As Figure 6As shown, the expansion joint 51 is provided at one end of the feed inlet 11, and the expansion joint 51 is provided at the other end of the feed inlet 11. In order to improve the sealing effect of the feed inlet 11 and play a role in installation and fixation, the expansion joint 51 is provided at the end of the feed inlet 11. At this time, only a small part of the high-temperature material enters the feed inlet 11 from the end of the feed inlet 11.
[0031] As Figure 5 shown, the expansion joint 51 is provided on the same side of the feed inlet 11. Since the high-temperature fossil energy or solid material enters the feed inlet 11 along the feed inlet 11, in order to prevent the high-temperature fossil energy or solid material from leaking out through the expansion joint 51, the expansion joint 51 can also be provided on the same side of the feed inlet 11, and the high-temperature fossil energy or solid material enters the feed inlet 11 from the other side of the feed inlet 11.
[0032] To increase the strength of the feed baffle 5 and avoid the low strength of the feed baffle 5 due to the existence of the expansion joint 51, the connecting plate 52 is used to connect the feed baffles 5 on both sides of the expansion joint 51. The connecting plate 52 covers the expansion joint 51, and bolts 53 are provided between the connecting plate 52 and the feed baffle 5. One bolt 53 is connected to the feed baffle 5 on one side of the expansion joint 51, and the other bolt 53 is connected to the feed baffle 5 on the other side of the expansion joint 51.
[0033] The connecting plate 52 is used to connect both sides of the expansion joint 51. Since the feed baffle 5 will expand after being heated, in order to reserve expansion space for expansion, bolts 53 and the connecting plate 52 are selected to fill the gap between the expansion joints 51. The gap can also be filled by connecting one side of the connecting plate 52 to the feed baffle 5 by bolts 53 or welding and leaving the other side unfixed. Both ends of the connecting plate 52 can also be fixed to both sides of the expansion joint 51 by bolts 53 or welding. The connecting plate 52 connects the expansion joint 51, and the connecting plate 52 facilitates the filling of sealing materials in the expansion joint 51 to achieve an overall sealing effect.
[0034] Figure 1 It is given that the connecting plate 52 is below the feed baffle 5. The connecting plate 52 can also be on the side of the expansion joint 51, or it is also feasible to have the connecting plate 52 on the side and below at the same time.
[0035] A number of expansion notches 54 are provided on the periphery of the feed baffle 5. The expansion notches 54 are evenly arranged on the periphery of the feed baffle 5. The expansion notches 54 increase the contact area between the feed baffle 5 and the air, accelerate the heat exchange rate between the feed baffle 5 and the air, and prevent the feed baffle 5 from deforming due to excessive temperature.
[0036] The expansion joint 51 is communicated with one of the expansion notches 54.
[0037] It further includes a discharge baffle 6, which is arranged around the discharge port 21 and fixedly arranged on the medium aggregator 2. One or more expansion joints can also be provided on the discharge baffle 6 in imitation of the feed baffle 5, and the function is similar to that of the expansion joint 51 on the feed baffle 5, so it will not be elaborated here.
[0038] It further includes a medium water inlet 22 and a steam outlet 12. The medium water inlet 22 is communicated with the medium aggregator 2, and the medium enters the medium aggregator 2 through the medium water inlet 22; the steam outlet 12 is communicated with the steam aggregator 1, and the generated steam after heating is collected by the steam aggregator 1 and discharged through the steam outlet 12, and is used in actual industrial production after being separated by a steam-water separator.
[0039] As Figure 7 described above, the expansion joint 51 includes one, and the number of expansion joints 51 is selected according to the temperature of the feed baffle 5 in actual production. The higher the temperature of the feed baffle 5 in actual production, the more the number of expansion joints 51, so as to avoid the normal use of the feed baffle 5 being affected by the thermal expansion and contraction phenomenon at high temperature.
[0040] Among them, the expansion joint 51 can be perpendicular to the edge of the discharge port 21 or not perpendicular to the edge of the discharge port 21. The inclination angle of the expansion joint 51 can be set according to needs. If there are multiple expansion joints 51, several expansion joints 51 can be arranged parallel to each other or not parallel.
[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
