Description

Technical Field

[0001] The utility model relates to the technical field of fluidized bed boiler tube bundles, in particular to a circulating fluidized bed boiler cooling tube bundle assembly. Background Technique

[0002] During the operation of a fluidized bed boiler, efficient heat conduction and dissipation are key factors to ensure the stable operation of the equipment and extend its service life. This is because a large amount of heat is generated when the fluidized bed boiler is working. If this heat cannot be conducted and dissipated in a timely and effective manner, the equipment temperature will be too high, which will in turn affect its normal operation and life. Therefore, for a fluidized bed boiler, having an efficient and reliable cooling system is crucial.

[0003] However, traditional fluidized bed boiler cooling systems often adopt simple heat dissipation structures, which have limited heat conduction efficiency and cannot meet the requirements of modern fluidized bed boilers for efficient heat dissipation. At the same time, due to design deficiencies, these traditional systems are also difficult to uniformly heat-treat the raw materials in the furnace, resulting in poor cooling effects and further affecting the overall performance of the fluidized bed boiler. In view of this, we propose a circulating fluidized bed boiler cooling tube bundle assembly. Content of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a circulating fluidized bed boiler cooling tube bundle assembly.

Through the design of the inlet pipe 4 and the outlet pipe 6, the cooling water can circulate, enhancing the cooling effect. At the same time, through the design of the flange and the connecting pipe 51, it is convenient for the installation and maintenance of the cooling tube bundle assembly. The design of the hollow turntable 54 and the heat conduction pipe assembly further improves the heat conduction efficiency, making the cooling effect of the fluidized bed boiler better. And the hollow turntable 54 can rotate, which not only improves the heat transfer efficiency but also stirs the raw materials in the fluidized bed boiler to improve the heating efficiency of the raw materials.

[0024] As a preference of this embodiment, an annular connecting plate 57 is integrally formed on the hollow turntable 54. The annular connecting plate 57 is rotatably connected to the disc 5 through a second bearing 58. By integrally forming the annular connecting plate 57 on the hollow turntable 54 and rotatably connecting it to the disc 5 through the second bearing 58, the connection stability and rotation flexibility between the hollow turntable 54 and the disc 5 are enhanced, and the structural strength and durability of the entire cooling tube bundle assembly are improved.

[0025] As a preference of this embodiment, teeth are provided on the circumferential outer wall of the hollow turntable 54, and a gear 55 is rotatably installed on the disc 5. The gear 55 meshes with the outer ring wall of the hollow turntable 54. By providing teeth on the circumferential outer wall of the hollow turntable 54 and meshing with the gear 55 rotatably installed on the disc 5, precise rotation control of the hollow turntable 54 is realized, and the uniformity and efficiency of heat conduction are improved.

[0026] Preferably, in this embodiment, an adjustment motor 50 with an output shaft coaxially fixed to a gear 55 is fixedly installed on a disk 5. By fixedly installing the adjustment motor 50 on the disk 5, the rotation of the gear 55 can be precisely controlled by the motor, further improving the automation degree and cooling efficiency of the cooling tube bundle assembly.

[0027] Preferably, in this embodiment, a base 2 is fixedly installed at the bottom of the heat dissipation water tank 1. On both sides of the base 2, an extension plate 20 is integrally formed. Two mounting holes are symmetrically opened on each extension plate 20. By fixedly installing the base 2 at the bottom of the heat dissipation water tank 1 and integrally forming the extension plates 20 on both sides of the base 2, a stable installation foundation is provided.

[0028] Preferably, in this embodiment, a mounting frame 3 is installed on the outer wall of the heat dissipation water tank 1. A mounting plate 31 is fixedly installed inside the mounting frame 3. A plurality of fan motors 33 are fixedly installed on the mounting plate 31. The output shaft of each fan motor 33 is coaxially fixed with a fan blade 32. By installing the mounting frame 3 on the outer wall of the heat dissipation water tank 1 and fixedly installing the mounting plate 31 and the fan motors 33 inside the mounting frame 3, active heat dissipation of the heat dissipation water tank 1 is achieved, further improving the cooling effect.

[0029] Preferably, in this embodiment, a protective net 30 is fixedly connected to the outer wall of the mounting frame 3 by bolts. By fixedly connecting the protective net 30 to the outer wall of the mounting frame 3, effective protection for the fan motors 33 is provided, preventing damage to the fan motors 33 by external debris, and improving the safety and durability of the entire assembly.

[0030] Preferably, in this embodiment, a water pump 40 is installed on the water inlet pipe 4. By installing the water pump 40 on the water inlet pipe 4, forced circulation of the cooling water is achieved, further improving the cooling efficiency and ensuring the stable operation of the fluidized bed furnace.

[0031] When the circulating fluidized bed furnace cooling tube bundle assembly of the present utility model is in use, it includes the following processes:

[0032] Cooling water circulation: The cooling water is introduced into the heat dissipation water tank 1 through the water inlet pipe 4. The water pump 40 installed on the water inlet pipe 4 provides power to achieve forced circulation of the cooling water. After absorbing heat in the heat dissipation water tank 1, the cooling water flows out through the water outlet pipe 6 to complete a cycle.

[0033] Heat conduction:

[0034] During the circulation process of the cooling water, heat exchange is carried out with the heat in the fluidized bed furnace through the heat conduction tube assembly. The heat conduction tube assembly includes a mounting tube 53 connected to two hollow turntables 54, and vertical tubes 52 between the mounting tubes 53. These pipe structures effectively conduct the heat from the fluidized bed furnace to the cooling water.

[0035] Rotation and agitation of the hollow turntable 54: The hollow turntable 54 is rotatably connected to the mounting pipe 53 through the first bearing 56 and can rotate freely on the disc 5. The teeth on the outer circumferential wall of the hollow turntable 54 are engaged with the gear 55 on the disc 5, and the gear 55 is driven by the adjustment motor 50 to achieve precise rotation control of the hollow turntable 54. The rotation of the hollow turntable 54 not only improves the efficiency of heat conduction but also agitates the raw materials in the fluidized bed furnace, improving the heating efficiency of the raw materials.

[0036] Active heat dissipation of the radiator tank 1: The mounting plate 31 and the fan motor 33 are fixed inside the mounting frame 3 installed on the outer wall of the radiator tank 1. A fan blade 32 is coaxially fixed on the output shaft of the fan motor 33, and the rotation of the fan blade 32 generates an air current to actively dissipate heat from the radiator tank 1, further improving the cooling effect.

[0037] Installation and maintenance of the components: The base 2 fixedly installed at the bottom of the radiator tank 1 provides a stable installation foundation, and the mounting holes on the extension plates 20 on both sides of the base 2 facilitate the fixed installation of the entire component. The ends of the water inlet pipe 4 and the water outlet pipe 6 far from the radiator tank 1 are connected to the connecting pipe 51 through flanges, and this design facilitates the installation and maintenance of the cooling tube bundle assembly.

[0038] Safety protection: The protective net 30 fixedly connected to the outer wall of the mounting frame 3 by bolts provides effective protection for the fan motor 33, preventing damage to the fan motor 33 by external debris.

[0039] In summary, the circulating fluidized bed furnace cooling tube bundle assembly of the present utility model realizes efficient cooling effect and uniform heating of the raw materials in the fluidized bed furnace through designs such as the circulation of cooling water, heat conduction, rotation and agitation of the hollow turntable 54, active heat dissipation of the radiator tank 1, and convenient installation and maintenance, ensuring the stable operation of the fluidized bed furnace.
