Description

Technical Field

[0001] This utility model relates to the field of ventilation beam technology, specifically an m-shaped ventilation beam structure. Background Technology

[0002] The serpentine tubes in boilers are mainly used to improve heat exchange efficiency. By increasing the length and surface area of ​​the tubes, the serpentine tubes can transfer heat more effectively.

[0003] When the economizer serpentine tubes in a boiler require support beams, forced ventilation is necessary inside the support beams to achieve cooling due to the high temperature of the flue gas. This type of beam is called a ventilation beam.

[0004] Traditional ventilation beams are arranged in parallel, and ventilation adopts a single beam with one inlet and one outlet at both ends. This structure requires sufficient space for the ventilation beam inlet and outlet areas, and requires a large number of supply fans, exhaust fans and ducts, resulting in a waste of space and a waste of the number of fans. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an M-shaped ventilation beam structure. By adopting the M-shaped structure, air can be introduced and discharged on the same side, saving installation space, reducing the number of fans and the length of pipes, and achieving the same cooling effect.

[0006] The purpose of this utility model is achieved through the following technical solution: an M-shaped ventilation beam structure for supporting the economizer serpentine tube in a boiler. The structure includes a longitudinal ventilation beam and multiple transversely arranged transverse ventilation beams. One end of each transverse ventilation beam is sequentially connected to the longitudinal ventilation beam, and both ends of the longitudinal ventilation beam are sealed with partitions to ensure a smooth ventilation channel while preventing air from flowing out from both ends of the longitudinal ventilation beam. The longitudinal ventilation beam and the multiple transversely arranged transverse ventilation beams together form an N-shaped or M-shaped ventilation beam, achieving air intake and exhaust on the same side, saving installation space. The air intake and exhaust ends of the multiple transverse ventilation beams are set according to the needs of the staff. One transverse ventilation beam can be used as a cold air inlet and the others as hot air outlets, or one transverse ventilation beam can be used as a hot air outlet and the others as cold air inlets. The number of air intake or exhaust transverse ventilation beams can be increased or decreased as needed. The transverse ventilation beams can be round tubes, hollow square tubes, or other tube types that can achieve ventilation. The material can be any material that can achieve internal and external heat exchange, facilitating heat exchange between the air inside the tube and the flue gas outside the tube.

[0007] n-type ventilation beam: The transverse ventilation beam includes a first transverse ventilation beam and a second transverse ventilation beam. One end of the first transverse ventilation beam and the second transverse ventilation beam are connected to the longitudinal ventilation beam in sequence. Both ends of the longitudinal ventilation beam are closed by partitions. The longitudinal ventilation beam, the first transverse ventilation beam and the second transverse ventilation beam together form an n-type ventilation beam. An air inlet is provided at the other end of the first transverse ventilation beam and an air outlet is provided at the other end of the second transverse ventilation beam, so as to realize air intake and exhaust on the same side and save installation space.

[0008] M-shaped ventilation beam: The transverse ventilation beam includes a first transverse ventilation beam, a second transverse ventilation beam, and a third transverse ventilation beam. One end of the first transverse ventilation beam, the second transverse ventilation beam, and the third transverse ventilation beam are connected to the longitudinal ventilation beam in sequence. The two ends of the longitudinal ventilation beam are sealed with partitions. The longitudinal ventilation beam, the first transverse ventilation beam, the second transverse ventilation beam, and the third transverse ventilation beam together constitute an M-shaped ventilation beam, realizing air intake and exhaust on the same side, saving installation space. As needed, the number of transverse ventilation beams can be increased, and the number of air inlets and outlets can be adjusted as needed.

[0009] A support beam is placed below the air inlet and outlet ends of the first, second, and third transverse ventilation beams. The support beam is used to support the air inlet and outlet ends of the first, second, and third transverse ventilation beams.

[0010] The partition includes a first partition and a second partition. The first partition is located in front of the connection between the longitudinal ventilation beam and the first transverse ventilation beam, and the second partition is located behind the connection between the longitudinal ventilation beam and the third transverse ventilation beam.

[0011] The connection points between the longitudinal ventilation beam and the first, second, and third transverse ventilation beams are all provided with openings, and the area of ​​the openings is not less than 80% of the ventilation channel area of ​​the first, second, and third transverse ventilation beams.

[0012] The opening is round, oblong, or elliptical. The airflow from the second transverse ventilation beam enters the longitudinal ventilation beam through the opening in the middle of the longitudinal ventilation beam, and then splits. Half of the airflow enters the first transverse ventilation beam through the opening at the top of the longitudinal ventilation beam, and the other half enters the third transverse ventilation beam through the opening at the bottom of the longitudinal ventilation beam.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] In one embodiment of this application: like Figures 1 to 3As shown, an M-shaped ventilation beam structure is used to support the economizer serpentine tube in a boiler. This structure includes a longitudinal ventilation beam 4, a first transverse ventilation beam 1, a second transverse ventilation beam 2, and a third transverse ventilation beam 3 arranged laterally. One end of each of the first, second, and third transverse ventilation beams is flush with the longitudinal ventilation beam 4 (i.e., their upper surfaces are flush). Both ends of the longitudinal ventilation beam 4 are sealed with partitions to ensure a smooth ventilation channel and prevent air from flowing out from either end. A cold air inlet is located at the other end of the second transverse ventilation beam 2, and hot air outlets are located at the other ends of the first and third transverse ventilation beams 1 and 3. Together, the longitudinal ventilation beam 4, the first transverse ventilation beam 1, the second transverse ventilation beam 2, and the third transverse ventilation beam 3 form an M-shaped ventilation beam. Cold air enters through the cold air inlet at the right end of the middle second transverse ventilation beam 2. After exchanging heat with the flue gas, the cold air temperature rises and flows to the left end of the second transverse ventilation beam 2 before entering the longitudinal ventilation beam 4. Figure 2 As shown, the air, after its temperature rises, is split at the left end of the second transverse ventilation beam 2. Half of it flows upward along the longitudinal ventilation beam 4 and enters the first transverse ventilation beam 1. After exchanging heat with the flue gas again, its temperature rises to form hot air, which then flows out from the hot air outlet at the right end of the first transverse ventilation beam 1. The other half flows downward along the longitudinal ventilation beam 4 and enters the third transverse ventilation beam 3. After exchanging heat with the flue gas again, its temperature rises to form hot air, which then flows out from the hot air outlet at the right end of the third transverse ventilation beam 3. This M-shaped ventilation beam structure can achieve three heat exchanges between cold air and flue gas, improving cooling efficiency.

[0020] The n-type ventilation beam structure is achieved by removing either the first transverse ventilation beam 1 or the third transverse ventilation beam 3.

[0021] In the second embodiment of this application: Based on the previous embodiment, this embodiment improves the partition. The other ends (i.e., air inlet and air outlet) of the first transverse ventilation beam 1, the second transverse ventilation beam 2, and the third transverse ventilation beam 3 are placed on the upper surface of the support beam 7. The support beam 7 is used to support the air inlet and air outlet ends of the first transverse ventilation beam 1, the second transverse ventilation beam 2, and the third transverse ventilation beam 3.

[0022] The partition includes a first partition 5 and a second partition 6, such as Figure 2 As shown, the first partition 5 is located above the connection between the longitudinal ventilation beam 4 and the first transverse ventilation beam 1, and the second partition 6 is located below the connection between the longitudinal ventilation beam 4 and the third transverse ventilation beam 3, to prevent air from flowing out from the upper or lower port of the longitudinal ventilation beam 4.

[0023] In the third embodiment of this application: Based on the first or second embodiment, this embodiment improves the longitudinal ventilation beam 4 and the three transverse ventilation beams. The connection points between the longitudinal ventilation beam 4 and the first transverse ventilation beam 1, the second transverse ventilation beam 2, and the third transverse ventilation beam 3 are all set as openings, and the area of ​​the openings is not less than 80% of the ventilation channel area in the first transverse ventilation beam 1, the second transverse ventilation beam 2, and the third transverse ventilation beam 3.

[0024] The opening can be round, oblong, or oval, such as... Figure 3 As shown, the opening is a vertical elliptical hole. The air from the second transverse ventilation beam 2 enters the longitudinal ventilation beam 4 through the opening, and then splits. Half of the air enters the first transverse ventilation beam 1 through the opening at the top of the longitudinal ventilation beam 4, and the other half enters the third transverse ventilation beam 3 through the opening at the bottom of the longitudinal ventilation beam 4.
