[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a flue gas spoiler component for a boiler, such as Figure 1-Figure 4 As shown, it includes a spoiler tube 1, a flue gas spoiler 3 is installed inside the spoiler tube 1, and positioning devices 2 are detachably installed at both ends of the spoiler tube 1. The flue gas spoiler 3 is a spiral structure formed by twisting a thin plate. The positioning device 2 is installed on one end of the spoiler tube 1. The positioning device 2 includes a cover plate 21, and a sealing ring 22 is installed at one end of the cover plate 21 near the spoiler tube 1. The inner wall of the cover plate 21 is provided with a card slot 23, and a card connection end 31 is provided at the end of the flue gas spoiler 3. The card connection end 31 is card-connected with the card slot 23. The flue gas spoiler 3 cleverly installed inside the spoiler tube 1 has a unique thin plate twisted spiral structure, which greatly improves the turbulence of the flue gas in the tube, thereby enhancing the heat exchange effect. At the same time, the positioning devices 2 at both ends not only ensure the stable position of the flue gas spoiler 3 in the spoiler tube 1, but also facilitate the assembly and maintenance of the equipment. In particular, the design of the positioning device 2, in which the cover plate 21 and the sealing ring 22 jointly ensure the sealing of the pipe end, effectively preventing the leakage of smoke. The card slot 23 on the inner wall of the cover plate and the card connection end 31 of the end of the smoke spoiler 3 are closely matched, which not only enhances the stability of the structure, but also simplifies the installation and disassembly process. This design not only optimizes the heat exchange performance, but also improves the overall reliability and operation convenience of the equipment.

[0023] In this embodiment, a plurality of spoiler plates 4 are installed on the inner wall of the spoiler tube 1. The spoiler plates 4 are arranged at equal intervals. A plurality of small holes 41 are opened on the surface of the spoiler plates 4 to facilitate the flow of smoke.

[0024] Specifically, the length of the flue gas spoiler 3 is smaller than that of the spoiler tube 1 , that is, the flue gas spoiler 3 is provided on a partial area of ​​the spoiler tube 1 , which can improve the heat exchange efficiency without increasing the flue gas resistance, thereby completing the function of the spoiler tube 1 smoothly.

[0025] Furthermore, the spoiler tube 1 is a smooth circular tube structure, and the width of the smoke spoiler 3 is adapted to the width of the inner wall of the spoiler tube 1 , which facilitates the installation and positioning of the smoke spoiler 3 .

[0026] Furthermore, the smoke spoiler 3 is arranged near the end of the spoiler tube 1 , and the end refers to the area through which the smoke entering the spoiler tube 1 finally flows.

[0027] Furthermore, the flow-deflecting pipe 1 is arranged between the furnace and the smoke box in the boiler, or between the smoke boxes, so as to facilitate the flow deflection of the smoke.

[0028] Furthermore, the spoiler tube 1 and the positioning device 2 are connected by bolts, positioning pins, or snaps, so that the spoiler tube 1 and the positioning device 2 can be easily assembled and disassembled.

[0029] Furthermore, along the direction of flue gas flow, the pitch of the spiral structure of the flue gas turbulator 3 gradually decreases, and its pitch gradually decreases along the direction of flue gas flow. This unique design not only further intensifies the turbulent mixing of the flue gas, but also allows the flue gas to contact the tube wall more fully during the flow process, thereby greatly improving the heat exchange efficiency. As the pitch gradually decreases, the flue gas will generate stronger vortex and shear force when flowing through the turbulator. These forces work together to make heat transfer more rapid and uniform. Therefore, this design optimization not only improves energy utilization efficiency, but also helps to reduce heat loss, providing strong support for the efficient and stable operation of the boiler.

[0030] When the smoke turbulence assembly for a boiler of the utility model is used, first when the boiler is working, the smoke generated enters the turbulence tube 1. The smoke first encounters the smoke turbulent 3 installed inside, whose unique spiral structure is formed by twisting a thin plate, effectively breaking the laminar flow state of the smoke and enhancing the turbulence. As the smoke flows along the turbulence tube, it will continuously collide and mix with the smoke turbulent 3 with a spiral structure, thereby greatly improving the heat exchange efficiency of the smoke.

[0031] In addition, the design of the smoke spoiler 3 also takes into account the characteristics of smoke flow. Along the direction of smoke flow, the pitch of the smoke spoiler 3 gradually decreases, and this design further intensifies the turbulent mixing of the smoke. As the pitch decreases, the smoke will produce a stronger vortex effect when flowing through the spoiler, making the heat transfer more rapid and uniform, thereby improving energy utilization efficiency.

[0032] Several spoilers 4 are installed inside the spoiler tube 1. These spoilers are arranged at equal intervals and have small holes 41 on their surfaces to facilitate the flow of smoke. These spoilers 4 further enhance the disturbance effect of the smoke and improve the heat exchange efficiency.

[0033] At the same time, the positioning devices 2 at both ends ensure the stable position of the smoke spoiler 3 in the spoiler tube 1. The positioning device 2 includes a cover plate 21 and a sealing ring 22, which ensures the sealing of the tube end and effectively prevents the leakage of smoke. The card slot 23 on the inner wall of the cover plate is tightly matched with the card connection end 31 of the end of the smoke spoiler 3, which enhances the stability of the structure.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
