Description

Technical Field

[0001] This invention relates to the field of heat regenerator technology, and more specifically, to a horseshoe flame kiln heat regenerator. Background Technology

[0002] During the production of medium and high borosilicate glass and medium and high alkali silicate glass, a large amount of volatiles are generated during the melting stage due to the composition characteristics of the glass raw materials. These volatiles have extremely strong brick-melting properties, and their melt viscosity increases significantly at low temperatures, making them very easy to adhere to the surface inside the heat storage chamber and form a firmly bonded deposit with the brick surface inside the heat storage chamber.

[0003] Currently, the industry standard practice is to introduce fuel through a channel at the bottom of the regenerator, using the high-temperature flame generated by combustion to burn off the brick surface inside the regenerator and remove deposits. However, because the flame propagation path of the bottom-burning regenerator is concentrated in the lower part of the regenerator, the flame cannot evenly cover the upper middle and side areas of the regenerator, resulting in incomplete removal of deposits and thus reducing the cleaning effect of the regenerator, failing to meet the cleaning requirements of the regenerator. Summary of the Invention

[0004] The problem addressed by this invention is how to improve the cleaning effect of the heat storage chamber.

[0005] To address the above problems, the present invention provides a horseshoe flame kiln regenerator.

[0006] In a first aspect, the present invention provides a horseshoe-flame kiln regenerator, comprising: a first wall and a second wall disposed opposite to each other along a first direction, and a third wall and a fourth wall disposed opposite to each other along a second direction, wherein the first wall, the second wall, the third wall and the fourth wall together enclose a receiving cavity, wherein the first direction and the second direction are perpendicular to each other and both are parallel to the horizontal direction; and a heating element, which is penetrated and connected to at least one of the first wall, the second wall, the third wall and the fourth wall to heat the inner wall of the receiving cavity.

[0007] The beneficial effects of the heat storage chamber of this invention are: By setting up the above structure, the first wall, the second wall, the third wall, and the fourth wall enclose and form a cavity. On the one hand, this provides a stable installation and working space for the bricks inside the heat storage chamber, ensuring the basic heat storage function of the heat storage chamber. On the other hand, the cavity avoids airflow turbulence caused by irregular space, creating uniform spatial conditions for heat transfer of subsequent heating elements.

[0008] Secondly, the first direction is perpendicular to the second direction and parallel to the horizontal direction, so that the first wall, the second wall, the third wall and the fourth wall form a symmetrical structure on the horizontal plane, which makes it easy for the heating elements to be evenly arranged on different walls, laying the foundation for subsequent multi-directional heating and avoiding heating dead corners caused by improper spatial direction design.

[0009] Furthermore, the heating element is directly connected to the wall, allowing heat to be supplied directly into the cavity from the side walls of the first, second, third, and fourth walls. This makes the heat transfer path of the heating element shorter and more direct, enabling precise application to the inner wall of the cavity. Heating elements can be installed on any one or more walls to achieve multi-directional and multi-angle heating, thus covering the upper middle and side areas of the heat storage chamber. This ensures that heat is evenly distributed throughout the cavity, allowing deposits adhering to various locations on the inner wall of the cavity to be burned off by high temperatures, completely decomposed, or removed. This significantly improves the deposit cleaning effect, thereby meeting the cleaning requirements of the heat storage chamber.

[0010] Optionally, at least one of the first wall, the second wall, the third wall, and the fourth wall is provided with an opening, and the heating end of the heating element extends into the receiving cavity through the opening.

[0011] Optionally, the heating element is a spray gun.

[0012] Optionally, the opening has a square cross-section in the vertical direction.

[0013] Optionally, the vertical extension length of the opening is between 110mm and 120mm, and the horizontal extension length of the opening is between 135mm and 145mm.

[0014] Optionally, it also includes a partition wall disposed between the third wall and the fourth wall to divide the receiving cavity into two independent chambers along the first direction.

[0015] Optionally, the first wall, the second wall, and the third wall are each provided with a plurality of openings, and the plurality of openings located on the same wall are arranged at intervals in the horizontal direction.

[0016] Optionally, the center distance between two adjacent openings located on the same wall is between 1m and 1.5m.

[0017] Optionally, each of the walls is provided with four of the openings.

[0018] Optionally, the heating element is provided with a control valve, which is used to control the opening or closing of the heating element. Attached Figure Description

[0024] It should be noted that the terms "a" and "a plurality of" used in this invention are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0025] like Figures 1 to 3 As shown, the horseshoe-flame kiln regenerator provided by the present invention includes: a first wall 11 and a second wall 12 arranged opposite to each other along a first direction, and a third wall 13 and a fourth wall 14 arranged opposite to each other along a second direction. The first wall 11, the second wall 12, the third wall 13 and the fourth wall 14 together enclose a receiving cavity 15. The first direction and the second direction are perpendicular to each other and both are parallel to the horizontal direction. A heating element 20 is connected to at least one of the first wall 11, the second wall 12, the third wall 13 and the fourth wall 14 to heat the inner wall of the receiving cavity 15.

[0026] In this embodiment, by setting the above structure, the first wall 11, the second wall 12, the third wall 13, and the fourth wall 14 enclose and form a receiving cavity 15. On the one hand, it provides a stable installation and working space for the bricks inside the heat storage chamber, ensuring the basic heat storage function of the heat storage chamber. On the other hand, the receiving cavity 15 avoids airflow turbulence caused by irregular space, creating uniform spatial conditions for the heat transfer of the subsequent heating element 20.

[0027] Secondly, the first direction is perpendicular to the second direction and parallel to the horizontal direction, so that the first wall 11, the second wall 12, the third wall 13, and the fourth wall 14 form a symmetrical structure on the horizontal plane, which makes it easy for the heating element 20 to be evenly arranged on different walls, laying the foundation for subsequent multi-directional heating and avoiding heating dead angles caused by improper spatial direction design.

[0028] Furthermore, the heating element 20 is directly connected to the wall, allowing heat to be supplied directly into the cavity 15 from the side walls of the first wall 11, the second wall 12, the third wall 13, and the fourth wall 14. This makes the heat transfer path of the heating element 20 shorter and more direct, enabling it to act precisely on the inner wall of the cavity. By installing the heating element 20 on any one or more walls, multi-directional and multi-angle heating can be achieved, covering the upper middle and side areas of the heat storage chamber. This ensures that the heat is evenly distributed throughout the cavity 15, allowing the deposits attached to the inner wall of the cavity to be burned by the high temperature, completely decomposed, or removed. This significantly improves the deposit cleaning effect, thereby meeting the cleaning requirements of the heat storage chamber.

[0029] Optionally, at least one of the first wall 11, the second wall 12, the third wall 13, and the fourth wall 14 is provided with an opening, through which the heating end of the heating element 20 extends into the receiving cavity 15.

[0030] like Figure 1By setting openings in the wall, a stable installation and insertion channel is provided for the heating element 20, allowing the heating end of the heating element 20 to extend directly into the cavity 15, rather than indirectly supplying heat from the outside of the cavity. This brings the heating end closer to the inner wall of the cavity, making heat transfer more direct and avoiding heat loss during propagation. This ensures that high-temperature energy acts on the sediment attachment area, improving the efficiency of burning and decomposing the sediment.

[0031] Secondly, the openings can be set on any one or more of the first, second, third, and fourth walls 14. With the through connection of the heating element 20, a multi-directional heating layout from the side and middle of the heat storage chamber is realized. This can cover the upper and side areas of the heat storage chamber that are difficult for the flame to reach, allowing the deposits in these locations to be fully burned by high temperature, significantly improving the overall cleaning effect.

[0032] Optionally, the heating element 20 is a spray gun.

[0033] With the above settings, the spray gun has the function of directional spraying of high-temperature flames. Its flames are highly concentrated and have a high temperature peak, which can accurately target the deposit attachment area on the inner wall of the heat storage chamber. This allows the high-temperature flames to be sprayed directly to the upper middle and side cleaning dead corners, quickly increasing the local temperature and causing the volatile melt with strong melting properties to melt, decompose or fall off rapidly, significantly improving cleaning efficiency.

[0034] Optionally, the vertical cross-section of the opening is square.

[0035] By setting openings in the wall, the square-section openings are adapted to the nozzle structure of the heating element 20, resulting in a higher fit between the heating element 20 and the inner wall of the opening when it is inserted, thus reducing installation gaps. On the one hand, this prevents the heating element 20 from shifting or falling off due to vibration during heating, ensuring that the heating end always accurately acts on the target area inside the receiving cavity 15; on the other hand, it reduces the airflow exchange channel between the cavity and the outside, reduces heat loss, ensures the stability of the high-temperature environment inside the cavity, and improves the efficiency of sediment burning.

[0036] In this embodiment, the vertical cross-section of the opening is rectangular.

[0037] like Figures 1 to 3 As shown, optionally, the vertical extension length of the opening is between 110mm and 120mm, and the horizontal extension length of the opening is between 135mm and 145mm.

[0038] With the above settings, the vertical extension length of 110mm-120mm and the horizontal extension length of 135mm-145mm match the nozzle size of the heating element 20. This provides ample installation space for the heating element 20, ensuring that the heating end can smoothly extend into the receiving cavity 15 and maintain a stable posture, while also preventing the heating element 20 from shaking after installation due to an excessively large opening size. This results in better contact between the heating element 20 and the inner wall of the opening, reducing heat leakage from the gap and ensuring that the high temperature released by the heating end can be concentrated on the deposit area on the inner wall of the cavity, thereby improving the efficiency of combustion decomposition.

[0039] In this embodiment, the vertical extension length of the opening can be 110mm, 115mm, 120mm, etc., and the horizontal extension length of the opening can be 135mm, 140mm, 145mm, etc.

[0040] Optionally, it also includes a partition wall located between the third wall 13 and the fourth wall 14 to divide the receiving cavity 15 into two independent chambers along the first direction.

[0041] With the above setup, the partition wall divides the receiving cavity 15 into two independent chambers. The heating element 20 of the corresponding wall can be used to heat the deposits in each chamber according to their distribution. This allows the heat to be applied more concentratedly to the inner wall of a single chamber, improving the accuracy and thoroughness of the cleaning.

[0042] In this embodiment, there are 12 heating elements 20, each heating element 20 corresponds to a control valve 21, and each chamber corresponds to six heating elements 20. The main pipeline of the six heating elements 20 corresponding to each chamber is controlled by a reversing valve 22, and the main pipeline of the two reversing valves 22 is controlled by a gas main valve 23.

[0043] like Figure 1 As shown, optionally, the first wall 11, the second wall 12 and the third wall 13 are provided with multiple openings, and the multiple openings located on the same wall are arranged at intervals in the horizontal direction.

[0044] With the above configuration, multiple openings are simultaneously provided on the first wall 11, the second wall 12, and the third wall 13. This means that the heating element 20 can be connected to the receiving cavity 15 from multiple lateral directions of the heat storage chamber, forming a multi-directional heating layout. This not only covers the upper part of the heat storage chamber but also heats the corresponding inner walls of each wall, ensuring that deposits at any position on the inner wall of the cavity can be burned by high temperature.

[0045] Secondly, the multiple openings on the same wall are distributed horizontally at intervals, so that the heating element 20 forms a uniform multi-point heating unit on the wall. This allows the heat to spread evenly in the horizontal direction, avoiding the situation of heat concentration in local areas on the same wall side, and ensuring that the deposits on the inner wall of the cavity corresponding to the same wall can be fully burned from one end to the other, further improving the comprehensiveness of the cleaning.

[0046] In this embodiment, the heating element 20 is a spray gun, and the high-temperature flame it sprays does not only act on a localized point directly in front, but has a certain radiation range. The single row of horizontally arranged spray guns can cover the area above and below their own installation height through the vertical radiation diffusion of the flame, achieving full coverage heating of the wall without the need for separate openings at the bottom and top.

[0047] Furthermore, when the flame of the spray gun radiates upwards, it can directly reach the surface of the top brick. Even if some heat storage chambers are relatively high and direct flame radiation cannot completely cover them, heat radiation conduction under high temperature conditions can still play a role. After the middle and lower parts are heated, the overall temperature inside the chamber rises, and the top area gradually rises to the temperature of the deposit decomposition temperature by absorbing the heat radiation from the surrounding environment, thus achieving indirect heating for descaling.

[0048] In addition, the hot air inside the heat storage chamber will form natural convection. After the spray gun heats the middle and lower areas, the hot air rises and the cold air sinks, forming a circulating airflow that drives the heat to diffuse to the bottom, further assisting in the cleaning of the bottom deposits.

[0049] like Figure 1 As shown, optionally, the center distance between two adjacent openings on the same wall is between 1m and 1.5m.

[0050] With the above configuration, after two adjacent heating elements 20 extend into the cavity through the opening, their heat radiation areas can connect and overlap, avoiding heating gaps on the same wall side. This ensures that the horizontal area of ​​the corresponding chamber wall on the same wall can be uniformly heated from one end to the other, allowing deposits at any position in the horizontal direction to be fully burned, improving the comprehensiveness of the cleaning.

[0051] In this embodiment, the center distance between two adjacent openings on the same wall can be set to 1m, 1.25m, or 1.5m.

[0052] Optionally, each wall has four openings.

[0053] With the above setup, each wall has four openings, which can form a uniform four-point heating layout in the horizontal direction of the conventional heat storage chamber wall. The heating element 20 corresponding to the four openings can achieve seamless connection of heat radiation, ensuring that the horizontal area of ​​the inner wall of the chamber corresponding to a single wall can be fully covered from one end to the other.

[0054] like Figure 3 As shown, optionally, the heating element 20 is provided with a control valve 21, which is used to control the opening or closing of the heating element 20.

[0055] With the above setup, each heating element 20 corresponds to an independent control valve 21, which can be adjusted according to the differences in sediment distribution in different areas of the heat storage chamber. For example, for areas with dense sediment, the corresponding heating element 20 can be turned on individually to enhance high-temperature burning; for areas where sediment has been cleaned or where there is no sediment, the control valve 21 can be turned off in time to avoid ineffective heating, allowing the heat to be concentrated on the area to be cleaned, thereby greatly improving the targeting and comprehensiveness of the cleaning.

[0056] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
