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 vertically rotatable louvers for equalizing flow. 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. The cooling triangle unit, as the core component of the indirect air-cooled system, has its overall cooling performance determined by the uniformity of airflow into the cooling columns on both sides and the overall ventilation resistance of the cooling triangle. In natural ambient wind, uneven airflow and large deviations in cooling performance are easily observed in the cooling columns on both sides of the cooling triangle unit. The airflow equalization device can distribute the airflow into the cooling triangle unit, balancing the airflow into the cooling columns on both sides and optimizing the overall cooling performance of the cooling triangle unit. However, when the ambient wind speed is high and there is a certain airflow deviation angle, the airflow into the cooling triangle directly impacts the airflow equalization device, which increases the airflow resistance inside the cooling triangle, reduces the overall ventilation volume, and affects 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 the ambient wind enters the cooling triangle unit's air inlet louvers at an angle, they can eliminate the air vortex induced on the leeward side of the flow equalization device while balancing or evenly distributing the air intake on both sides of the cooling triangle. However, when the ambient wind at high speeds enters the cooling triangle unit at an angle, the flow equalization device exhibits significant resistance, which can actually reduce the cooling performance of the cooling triangle unit. This invention provides a cooling triangle unit with vertically rotatable flow equalization louvers, which can be adjusted according to the ambient wind speed and direction: at low ambient wind speeds, the louvers can be closed to achieve airflow equalization on the cooling triangle's air side; at high ambient wind speeds and with a certain air intake deviation angle, the louvers can be opened at a certain angle to reduce the ventilation resistance inside the cooling triangle unit, optimize the ambient wind distribution inside the cooling triangle unit, and improve the heat exchange performance of the cooling triangle unit. Summary of the Invention

[0004] The purpose of this invention is to overcome the problem of increased ventilation resistance inside the cooling triangle unit caused by the addition of a flow equalization device when there is a large ambient wind speed and a certain air inlet deviation angle. This invention applies for a cooling triangle unit with vertically rotating louvered flow equalization louvers. The vertically rotating louvered flow equalization device can be freely adjusted according to the ambient wind speed and the air inlet deviation angle of the cooling triangle unit. At low ambient wind speeds, the louvers can be adjusted to the closed state to achieve airflow equalization on the cooling triangle. At high ambient wind speeds and small air inlet deviation angles, the louvers can be adjusted to open at a certain angle, which can reduce the ventilation resistance of the cooling triangle unit and achieve airflow equalization on the cooling triangle. At high ambient wind speeds and large air inlet deviation angles, the louvers can be adjusted to the fully open state to reduce the ventilation resistance inside the cooling triangle unit, reduce the adverse effects of the flow equalization device, optimize the internal airflow distribution of the cooling triangle unit, and improve the heat exchange performance of the cooling triangle unit.
