Description

Technical Field

[0001] This invention belongs to the field of indirect air-cooled towers in thermal power plants, and specifically relates to a cooling triangular unit with an integrated rotating plate-type flow equalization and antifreeze device. Background Technology

[0002] Indirect air-cooled towers rely on ambient wind to cool circulating water. Therefore, the cooling performance of indirect air-cooled systems is easily affected by ambient wind. As the core component of the indirect air-cooled system, the uniformity of airflow into the cooling columns on both sides of the cooling triangle unit and the antifreeze capability of the cooling triangle unit are crucial to its cooling performance. In summer, uneven airflow is very likely to occur on both sides of the cooling triangle unit; in winter, the ambient wind speed is high and the airflow inclination angle is large, causing the ambient wind entering the cooling triangle to directly hit the cooling columns, resulting in excessively low surface temperatures of the cooling columns and severely affecting the overall cooling performance of the cooling triangle unit.

[0003] Chinese Patent No. ZL 2015 1 0055635.6 discloses an air-side flow equalization device for a cooling triangle in an indirect cooling tower. The device comprises at least one set of flow equalization components arranged circumferentially along the indirect cooling tower. Specifically, it includes a cooling triangle. A first flow equalization plate is provided within the cavity of the cooling triangle to change the direction of the incoming airflow. The first flow equalization plate is arranged along the symmetrical plane of the middle of the cooling triangle and extends outward to the outside of the cooling triangle. Second and third flow equalization plates are respectively provided on the outer end faces of the cooling columns on both sides of the cooling triangle to gather and guide the incoming airflow. The second and third flow equalization plates extend outward along the radial line of the indirect cooling tower. The first, second, and third flow equalization plates are all arranged vertically. This invention, through the cooperation of three sets of flow equalization plates, reduces the degree of airflow deviation at the air inlet of the cooling triangle, eliminates the low-speed vortex region of the air within the cooling triangle, and maximizes the airflow equalization effect on the cooling triangle. Patent No. 202111545557.X describes a cooling triangular unit equipped with a flow equalization device with a central jet gap. This unit, based on evenly distributing the airflow into the cooling triangle, eliminates the vortices induced by the incoming air on the leeward side of the flow equalization device through the jets formed by the central jet gaps, thereby improving the cooling performance of the cooling columns on both sides of the cooling triangular unit and its overall cooling performance. Patent No. 202111610358.2 describes a cooling triangular unit equipped with a flow equalization device that alternates between jet flow equalization and cooling performance. This unit, based on balancing the airflow into the left and right sides of the cooling triangle, eliminates the multi-stage vortices formed by the incoming air on the leeward side of the flow equalization device through multi-stage jets formed by multi-stage jet gaps, thereby improving the cooling performance of the cooling columns on both sides. The aforementioned flow equalization devices are all fixed flow equalization devices. When ambient wind enters the cooling triangle unit's air inlet louvers at an angle, they can eliminate air vortices induced on the leeward side of the flow equalization device while balancing or evenly distributing the airflow on both sides of the cooling triangle. However, in winter, when ambient wind enters the cooling triangle unit at an angle, such flow equalization devices cannot prevent the ambient wind from directly impacting the cooling column; instead, they reduce the cooling performance of the cooling triangle unit. This invention applies for a cooling triangle unit with a rotating plate-type integrated flow equalization and antifreeze device. This device can adjust the angle between the rotating plate and the cooling column according to the ambient wind speed and direction, thereby achieving the purpose of flow equalization and antifreeze. In summer, the rotation angle of the rotating plate can be adjusted to coincide with the vertical center symmetry plane of the cooling triangle unit, thus achieving flow equalization for the cooling triangle unit. In winter, when the ambient wind speed is high and the air inlet angle is large, the rotation angle of the rotating plate can be adjusted to prevent the ambient wind from directly impacting the cooling column, thus achieving antifreeze for the cooling triangle unit. Summary of the Invention

[0004] The purpose of this invention is to overcome the problems of uneven airflow in cooling triangular units and excessively low surface temperature of the cooling column caused by ambient wind blowing directly into it during winter. This invention discloses a cooling triangular unit with an integrated rotating plate-type flow equalization and antifreeze device. This device can adjust the angle between the rotating plate and the cooling column according to the ambient wind speed and direction, thereby achieving both flow equalization and antifreeze protection. In summer, the rotation angle of the rotating plate can be adjusted to align with the vertical center symmetry plane of the cooling triangular unit, thus equalizing the flow. In winter, when the ambient wind speed is high and the airflow angle is large, adjusting the rotation angle of the rotating plate prevents the ambient wind from blowing directly into the cooling column, thus preventing the cooling triangular unit from freezing.
