Description

TECHNICAL FIELD

[0001] The present application belongs to the field of natural draft indirect air cooling tower of thermal / nuclear power station, and particularly relates to a cooling triangular unit with vertically adjustable flow uniformizing device module. BACKGROUND

[0002] The natural draft indirect air cooling system draws ambient wind by natural convection of the air cooling tower, and cools the circulating water in the cooling triangular unit, and has the characteristics of water and energy saving and low noise, and is widely used in thermal power plants in the northwest of China where water resources are scarce. The cooling triangular unit is a core component of the indirect air cooling system, and its performance is directly related to the economy, safety and stability of the generator unit operation. Ambient wind is one of the main factors affecting the cooling characteristics of the natural draft indirect air cooling tower. In the ambient wind, the cooling columns on both sides of the cooling triangular unit are prone to uneven air intake and large cooling performance deviation, and the airflow distribution inside the cooling triangular unit is also greatly affected, which seriously affects the heat exchange effect of the cooling triangular unit, and further reduces the cooling performance of the indirect air cooling tower.

[0003] Chinese patent, patent number ZL 2015 1 0055635.6, discloses a gas side flow uniformizing device of an indirect cooling tower cooling triangle, which is composed of at least one group of flow uniformizing components arranged along the circumference of the indirect cooling tower, specifically including a cooling triangle, a first flow uniformizing plate for changing the flow direction of the cooling triangle is arranged in the cavity of the cooling triangle, and the first flow uniformizing plate is arranged along the middle symmetry plane of the cooling triangle and extends outward to the outside of the cooling triangle; the outer end face of the cooling column on both sides of the cooling triangle is respectively provided with a second and a third flow uniformizing plate for converging and guiding the incoming air, and the second and third flow uniformizing plates are respectively arranged outward along the radial line of the indirect cooling tower, and the first, second and third flow uniformizing plates are all arranged in the vertical direction. The invention reduces the deviation of the incoming air at the air inlet of the cooling triangle by the cooperation of the three groups of flow uniformizing plates, eliminates the low-speed vortex area of the air in the cooling triangle, and maximizes the flow uniformizing effect of the incoming air of the cooling triangle. Patent No. 202111545557.X, a cooling triangle unit installed with a flow uniformizing device with a middle jet gap, on the basis of uniformizing the incoming air of the cooling triangle, the jet flow formed by the middle jet gap eliminates the vortex induced by the incoming air at the leeward side of the flow uniformizing device, thereby improving the cooling performance of the cooling columns on the left and right sides of the cooling triangle unit and the overall cooling performance. Patent No. 202111610358.2, a cooling triangle unit installed with a flow uniformizing device with jet flow alternating action, on the basis of balancing the incoming air on the left and right sides of the cooling triangle, the multi-stage jet flow formed by the multi-stage jet gap eliminates the multi-stage vortex formed by the incoming air at the leeward side of the flow uniformizing device, thereby improving the cooling performance of the cooling columns on the left and right sides. The flow uniformizing devices of the above-mentioned patents all belong to fixed flow uniformizing devices. When the environmental wind obliquely enters the air inlet louvers of the cooling triangle unit, the air vortex induced at the leeward side of the flow uniformizing device can be eliminated on the basis of balancing or uniformizing the incoming air on the left and right sides of the cooling triangle. However, when the environmental wind with high speed obliquely enters the cooling triangle unit, the flow uniformizing device has a large resistance effect, which may reduce the cooling performance of the cooling triangle unit. The present application applies a cooling triangle unit with vertically adjustable flow uniformizing device modules. The vertically adjustable flow uniformizing device modules can adjust the opening degree of the roller blinds according to the environmental wind speed and direction: when the environmental wind speed is small, the roller blinds of the flow uniformizing modules can be completely unfolded to realize the gas side flow uniformizing effect of the cooling triangle; when the environmental wind speed is large and the incoming air is oblique, the opening degree of the roller blinds of the flow uniformizing device modules can be adjusted to optimize the coupling effect of the incoming air resistance and the gas side flow uniformizing of the cooling triangle unit.
