Description

Technical Field

[0001] This utility model belongs to the technical field of heating furnace equipment, and in particular relates to a furnace tube support structure for an organic heat carrier heating furnace. Background Technology

[0002] Organic heat carrier heaters are widely used in many industrial fields such as chemical, petroleum, and textile industries. Their core function is to provide stable heat for various production processes by heating the organic heat carrier. In the structure of an organic heat carrier heater, the support structure of the furnace tube is crucial, as it directly affects the stability, safety, and service life of the heater.

[0003] The existing support structure for the furnace tubes of organic heat carrier heating furnaces is mostly an annular plate with through holes, through which the furnace tubes pass. However, this structure results in poor water flow in the furnace body, leading to significant heating differences. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a furnace tube support structure for an organic heat carrier heating furnace. By fixing a support plate at the same horizontal plane as the return flue inside the furnace, and opening a through hole on the support plate for the return flue to pass through, the space occupied by the support plate is small, and there are gaps between the support plates, which ensures the normal flow of water when boiling inside the furnace and improves the uniformity of heating.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An organic heat carrier heater tube support structure includes a furnace body; a combustion chamber is provided at the bottom of the furnace body, an igniter is provided in the combustion chamber, a water inlet pipe is fixed at the water inlet on the upper side of the furnace body, a drain pipe is fixed at the drain outlet at the bottom left side of the furnace body, several return flue pipes are fixed in the furnace body, the return flue pipes are connected to the inner cavity of the combustion chamber through a flue pipe, an exhaust pipe is fixed at the exhaust outlet of the return flue pipes, and a support plate is fixed on the inner wall of the furnace body at the same horizontal plane as the return flue pipes. Each support plate has a through hole, through which the return flue pipes pass. By fixing the support plate at the same horizontal plane as the return flue pipes in the furnace body and opening the through holes on the support plate for the return flue pipes to pass through, the space occupied by the support plate is small, and there are gaps between the support plates, which ensures the normal flow of water in the furnace body when boiling and improves the uniformity of heating.

[0007] Furthermore, the support plates are fixed together by several equidistant reinforcing ribs. By setting the reinforcing ribs, the overall structural strength of the support plates is enhanced, making the support plates more stable and reliable for the return flue. Even under long-term operation of the furnace and the action of high-temperature flue gas, the position of the return flue can be kept stable, ensuring the smooth progress of the heat exchange process.

[0008] Furthermore, each through hole of the support plate is fitted with a ceramic fiber sleeve, which is fitted onto the return flue. The ceramic fiber sleeve has good heat insulation properties, which can effectively reduce the heat transfer from the return flue to the support plate and prevent the support plate from being damaged due to high temperature.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: By fixing a support plate at the same level as the return flue pipe inside the furnace body, and opening a through hole on the support plate for the return flue pipe to pass through, the support plate occupies little space and there are gaps between the support plates, ensuring normal flow of water when boiling inside the furnace body and improving the uniformity of heating. By setting reinforcing ribs, the overall structural strength of the support plate is enhanced, making the support plate support the return flue pipe more stable and reliable. Even under long-term operation of the furnace body and the action of high-temperature flue gas, the position of the return flue pipe can be kept stable, ensuring the smooth progress of the heat exchange process. The ceramic fiber sleeve has good heat insulation performance, which can effectively reduce the heat transfer from the return flue pipe to the support plate and prevent the support plate from being damaged due to high temperature.

[0015] See appendix Figure 1-2 As shown, an organic heat carrier heating furnace tube support structure includes a furnace body 1; a combustion chamber 2 is provided at the bottom of the furnace body 1, and an igniter 3 is provided in the combustion chamber 2; a water inlet 4 is fixed at the water inlet on the upper side of the furnace body 1, and a drain pipe 5 is fixed at the drain outlet at the bottom left side of the furnace body 1; several return smoke pipes 6 are fixed inside the furnace body 1, and the return smoke pipes 6 are connected to the inner cavity of the combustion chamber 2 through a smoke supply pipe 7; an exhaust pipe 8 is fixed at the exhaust outlet of the return smoke pipes 6; and a support plate 9 is fixed on the inner wall of the furnace body 1 at the same horizontal plane as the return smoke pipes 6. Each support plate 9 has a through hole, through which the return smoke pipes 6 pass. By fixing the support plate 9 at the same horizontal plane as the return smoke pipes 6 inside the furnace body 1 and opening the through hole on the support plate 9 for the return smoke pipes 6 to pass through, the space occupied by the support plate 9 is small, and there are gaps between the support plates 9, which ensures the normal flow of water when boiling in the furnace body 1 and improves the uniformity of heating.

[0016] Each of the support plates 9 is fixed by a number of equally spaced reinforcing ribs 10. By setting the reinforcing ribs 10, the overall structural strength of the support plates 9 is enhanced, making the support plates 9 support the return flue pipe 6 more stable and reliable. Even under the long-term operation of the furnace body 1 and the action of high-temperature flue gas, the position of the return flue pipe 6 can be kept stable, ensuring the smooth progress of the heat exchange process.

[0017] Ceramic fiber sleeves 11 are fitted into the through holes of the support plate 9. The ceramic fiber sleeves 11 are fitted onto the return smoke pipe 6. The ceramic fiber sleeves 11 have good heat insulation performance, which can effectively reduce the heat transfer from the return smoke pipe 6 to the support plate 9 and prevent the support plate 9 from being damaged due to high temperature.

[0018] Working principle: Fluid is added into the furnace body 1 through the water supply pipe 4. The fuel is ignited by the igniter 3 in the combustion chamber 2. The fuel burns in the combustion chamber 2 to produce high-temperature flue gas. This high-temperature flue gas enters the return flue pipe 6 through the flue pipe 7. During the flow in the return flue pipe 6, it exchanges heat with the fluid in the furnace body 1, thus heating it. The support plate 9 fixed to the inner wall of the furnace body 1 plays a key role in supporting the return flue pipe 6. The return flue pipe 6 passes through the through hole on the support plate 9. The ceramic fiber sleeve 11 is sleeved between the return flue pipe 6 and the through hole of the support plate 9. The ceramic fiber sleeve 11 has good heat insulation performance, which can effectively reduce the heat transfer from the return flue pipe 6 to the support plate 9, prevent the support plate 9 from being damaged due to high temperature, and also reduce heat loss. Furthermore, the support plates 9 are fixed together by a number of equidistant reinforcing ribs 10, which enhances the overall structural strength of the support plates 9 and makes the support plates 9 support the return flue pipe 6 more stable and reliable. Even under the long-term operation of the heating furnace and the action of high-temperature flue gas, the position of the return flue pipe 6 can be kept stable, ensuring the smooth progress of the heat exchange process. Finally, the flue gas after heat exchange is completed is discharged from the furnace body 1 through the exhaust pipe 8. When it is necessary to discharge the fluid in the furnace body 1, it can be discharged through the drain pipe 5.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0020] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
