Description

Technical Field

[0001] This invention relates to the field of power plant facility technology, and specifically to a cooling triangular support system. Background Technology

[0002] Indirect air-cooled towers, also known as indirect cooling towers, are generally hyperbolic towers. They are indispensable main structures in thermal power plants. Existing cooling triangular supports have cooling triangular legs of a certain height at the bottom, with the radiator placed above these legs. The top of the radiator is connected to a widened platform. The cooling triangular legs bear the weight of the radiator and the horizontal load. The top of the cooling triangular support is supported by the side of the widened platform, which in turn is supported by the X-shaped column embedded parts of the indirect cooling tower. When the windward side of the radiator is subjected to wind load, part of the load is transferred to the cooling triangular legs at the bottom, and another part is transferred to the widened platform at the top. The indirect cooling tower participates in the overall stress distribution, resulting in complex connections and unclear force transmission paths. With the continuous expansion of power plant scale, larger heat exchange areas and taller indirect cooling towers are required. Current methods increase the heat exchange area by increasing the height of the radiator. As the height of the radiator increases, the requirements for overall rigidity also increase. Auxiliary components need to be set up to increase lateral rigidity. The indirect cooling tower participates in the overall stress, making the connection more complex and the force transmission path more unclear, which significantly increases the design difficulty. Summary of the Invention

[0003] In view of this, the present invention provides a cooling triangular support system to solve the problems that, as the scale of power plants continues to expand, the method of increasing the heat exchange area by increasing the height of the radiator increases the overall rigidity requirements, requiring the installation of auxiliary components to increase lateral rigidity, the participation of the indirect cooling tower in the overall stress, the complex connection, the unclear force transmission path, and the significant increase in design difficulty.

Beneficial effects: This application adopts the above technical solution, integrating the cooling triangular support and the extended platform into a single structure, completely independent of the indirect cooling tower structure. The cooling triangular support system has a simple structural connection and a clear force transmission path, ensuring the structural safety of the cooling triangular support system; at the same time, it simplifies the design difficulty of the indirect cooling tower, significantly saving design time and costs. Furthermore, mounting the radiator on the cooling triangular support significantly improves the overall rigidity of the radiator, overcoming the height limitations of traditional radiators and enabling ultra-high radiator installation.

[0018] like Figures 1 to 7 One specific embodiment of the cooling triangular support system shown includes: a cooling triangular support 1, an extended platform 2, and a radiator. The cooling triangular support system described in this application is used in power plants, particularly thermal power plants.

[0019] like Figure 1 As shown, the cooling triangular brackets 1 are arranged at intervals around the indirect cooling tower, forming a closed circular structure. The extended platform 2 is cantilevered to the top of the inner ring of the cooling triangular brackets 1, and the extended platform 2 and the cooling triangular brackets 1 form an integrated structure. The radiator is installed on the cooling triangular brackets 1, significantly improving the overall rigidity of the radiator, which is suitable for ultra-high cooling tower heat dissipation systems. The extended platform 2 is detached from the existing X-shaped column embedded parts of the indirect cooling tower, that is, it is disconnected from the indirect cooling tower. The structural connection is simple, the force transmission path is clear, and the safety of the cooling triangular bracket system is ensured. At the same time, it simplifies the design difficulty of the indirect cooling tower and significantly saves design time and costs. Specifically, the radiator can be hung inside the cooling triangular brackets 1 to meet the cooling requirements.

[0020] Furthermore, a displacement gap for lateral deformation is reserved between the widening platform 2 and the intercooling tower.

[0021] Furthermore, such as Figure 3 and Figure 7 As shown, a louver 3 is hung on the outside of the cooling triangular bracket; the cooling triangular bracket system has a first state in which the cooling triangular bracket 1 and the indirect cooling tower form a closed whole when the louver 3 is closed; and a second state in which air is introduced into the indirect cooling tower when the louver 3 is open.

[0022] Furthermore, such as Figure 1 As shown, the expansion platforms 2 are spaced apart. When the expansion platforms 2 are made of steel, the amount of steel used is significantly reduced.

[0023] Specifically, such as Figure 4 and Figure 7 As shown, a purlin structure 4 is provided between adjacent widening platforms 2, and a first enclosure structure 16 is laid on the widening platforms 2 and the purlin structure 4.

[0024] Specifically, a second enclosure structure is provided at the bottom of the cooling triangular bracket 1.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, the cooling triangular bracket 1 includes: multiple inner main chords 5, multiple outer main chords 6, multiple transverse supports 9, and diagonal web members 11. The cooling triangular bracket 1 is installed in segments. The multiple inner main chords 5 are arranged vertically in the inner ring; adjacent inner main chords 5 are connected by inner web members 7. The multiple outer main chords 6 are arranged vertically in the outer ring of the cooling triangular bracket 1; adjacent outer main chords 6 are connected by outer web members 8; the louvers 3 are hung on the outer web members 8. The multiple transverse supports 9 connect the inner main chords 5 and outer main chords 6 horizontally; the transverse supports 9 are double-layered and are suitable for supporting the cooling tube bundle 10 of the radiator. The diagonal web members 11 connect adjacent transverse supports 9 at different heights along the inclined direction.

[0026] Furthermore, such as Figure 2 As shown, the cooling triangular support system described in this application further includes: multiple support members 12, which are connected along the inclined direction to the position of the widened platform 2 near the cantilever end and the inner main chord 5.

[0027] Specifically, such as Figure 5 and Figure 6 As shown, the inner main chord 5 and the outer main chord 6 are collectively referred to as chords; the number of chords is determined by the number of radiators. The outer web 8 and the inner web 7 are collectively referred to as webs; the chords are connected to the horizontal portion of the irregular connecting plate 13 by fasteners 14; the transverse support 9 is connected to the chords via the vertical portion of the irregular connecting plate 13 using fasteners 14; the webs are connected to the chords via the vertical portion of the irregular connecting plate 13 using fasteners 14. The fasteners 14 can be bolts.

[0028] Furthermore, such as Figure 5 As shown, several stiffening plates 15 are provided on both the irregular connecting plate 13 and the chord.

[0029] The cooling triangular support system described in this application can be prefabricated in the factory and installed on site using bolts, which significantly speeds up the construction cycle.
